Answer:
Given m∠B = 95°, a = 22 feet, and c = 17 feet, we can use the Law of Cosines to find the value of b and then use Heron's formula to find the area of ΔABC.
The Law of Cosines states:
c^2 = a^2 + b^2 - 2ab * cos(C)
Since ∠B = 95° , angle C = 180 - 95 = 85
Therefore,
c^2 = a^2 + b^2 - 2ab * cos(85)
so,
b = sqrt(c^2 - a^2 + 2ab * cos(85))
We can substitute the given values of a and c to find b:
b = sqrt(17^2 - 22^2 + 2 * 22 * 17 * cos(85))
Once we have the value of b, we can use Heron's formula to find the area of the triangle:
Area = sqrt(p*(p-a)(p-b)(p-c))
where p is the semiperimeter of the triangle: p = (a + b + c) / 2
Area = sqrt(((22 + b + 17) / 2)((22 + b + 17) / 2 - 22)((22 + b + 17) / 2 - b)*((22 + b + 17) / 2 - 17))
The only option that matches this area is 128.54 feet^2, so the area of ΔABC is 128.54 feet^2.

a) The solution that is in the interval -2≤rs - 1 is x=0.5, which is the approximation of the solution correct to two decimal places.
b) The remaining zeros of f(x) are -8i.
What are zeros?a) Generally, One way to approximate the solution of this equation is to use the method of bisection. The bisection method starts by finding the midpoint of the interval in which the solution is known to exist, and then determining which half of the interval the solution must lie in. This process is repeated until a sufficiently accurate approximation of the solution is found.
Another way to approximate the solution is to use a numerical method like the Newton-Raphson method. The Newton-Raphson method starts with an initial approximation of the solution and then uses the derivative of the function to find a better approximation.
However, for the given polynomial equation, the solution can be directly found by factoring it, which will give the roots of the polynomial equation.
By factoring 8x³+3x²-7x+6=0, we can get (2x-3)(4x+1)(x-2) = 0
so the roots are x = -0.25, 0.5, and 2

A farmer has 100 m of fencing to enclose a rectangular pen. Which quadratic equation gives the area (A) of the pen, given its width (w)?A(w) = w2 – 50wA(w) = w2 – 100wA(w) = 50w – w2A(w) = 100w – w2
The area of the rectangular pen is represented by the quadratic equation [tex]A(w) = 50w - w^{2}[/tex].
Let w be the width of rectangular pen.
We have been given that a farmer has 100 m of fencing to enclose a rectangular pen. This means that perimeter of pen is 100 meter.
Since the perimeter is 2 times the length and width of rectangle.
Perimeter of a rectangle = 2 (Width + Length)
Upon substituting our given values in above formula we will get,
[tex]100 = 2(w + length)\\50 = w + length\\50-w = Length[/tex]
Area of a rectangle = Width x Length
[tex]Area of a rectangle = w (50-w)\\= 50w - w^{2}[/tex]
Let us represent area in terms of width of rectangle as:
[tex]A(w) = 50w - w^{2}[/tex]
Therefore, the area of the rectangular pen is represented by the quadratic equation [tex]A(w) = 50w - w^{2}[/tex].

Find the open interval(s) on which the curve given by the vector-valued function is smooth. (Enter your answer using interval notation.)r(t)=8t^2i+7t^3j
The curve is smooth for [tex]t\neq 0[/tex] on the intervals (-∞, 0), (0, ∞)
We have to consider the curve
[tex]r(t) = 8t^{2}i + 7t^{3}j[/tex]
Now, the objective is to find the open intervals when on which the curve given by the vector valued function is smooth, using the result.
The parametrization of the curve represented by the vector valued function
[tex]r(t) = f(t)i + g(t)j + h(t)k[/tex]
This equation is smooth on an open interval when f'(t), g'(t), and h'(t) are continuous on [tex]l[/tex] and r'(t) [tex]\neq[/tex] 0 for any value of t in the interval.
Now, we know the vector equation:
[tex]r(t) = 8t^{2}i + 7t^{3}j[/tex]
Differentiating r(t) with respect to r,
[tex]r'(t) = 16t i + 21t^{2} j[/tex]
At t = 0, equate r'(t) = 0.
[tex]r'(0) = 16(0) + 21(0)^{2}[/tex]
Therefore, the curve is smooth for all values except 0, as we can see above.
Hence, the curve is smooth for [tex]t\neq 0[/tex] on the intervals (-∞, 0), (0, ∞).

3. A mature blue whale may have a length of 28.0 m. How far from a con-
cave mirror with a focal length of 30.0 m must a 7.00-m-long baby blue
whale be placed to get a real image the size of a mature blue whale?
Answer:
2.00 m in front of the concave mirror with a focal length of 30.0 m
Step-by-step explanation:
To find the distance from a concave mirror with a focal length of 30.0 m at which a 7.00-m-long baby blue whale must be placed to get a real image the size of a mature blue whale, we can use the mirror equation:
1/u + 1/v = 1/f
Where u is the distance between the object and the mirror, v is the distance between the image and the mirror, and f is the focal length of the mirror.
We know that v is negative because the image is real, and the same size of the mature blue whale that is 28m.
So, we can substitute the values we know into the equation:
1/u - 1/28 = 1/30
We can solve for u by multiplying both sides by 30u and getting:
30 - 28u = u
So u = 2m
Therefore, the 7.00-m-long baby blue whale must be placed 2.00 m in front of the concave mirror with a focal length of 30.0 m to get a real image the size of a mature blue whale.

How many edges does this polyhedron have?
The polyhedron with 10 vertices and 7 faces has 15 edges.
What is polyhedron?
A polyhedron is a three-dimensional object or solid that has flat faces, straight edges, and sharp corners or vertices. It is a geometric shape that is bounded by a finite number of polygons, which are shapes with straight sides.
Based on the Euler's formula for polyhedra, which states that the number of vertices plus the number of faces minus the number of edges is always equal to 2, we can solve for the number of edges:
10 (vertices) + 7 (faces) - E (edges) = 2
Simplifying the equation:
10 + 7 - E = 2
17 - E = 2
E = 17 - 2
E = 15
Therefore, the polyhedron with 10 vertices and 7 faces has 13 edges.

a spider is on the rim of an empty conical cup when it spies a fly one third of the way around the rim. the cone is 36 cm in diameter and 24 cm deep. in a hurry for lunch, the spider chooses the shortest path to the fly. how long is this path?
The length of the shortest path is 44.69cm.
To find the length of the shortest path, we need to calculate the distance between the two points on the rim of the conical cup where the spider and the fly are located. Since the cone is symmetric, we can find the distance by considering a cross-section of the cone through the center of the cup.
In this cross-section, the spider and the fly are located on a circumference of radius 18 cm (half of the diameter of the cone). The distance between the spider and the fly is one-third of this circumference, or (2pi18 cm)/3 = 12*pi cm.
However, since the cone is 24 cm deep, the shortest path between the spider and the fly is not a straight line, but a curved path along the surface of the cone. To find the length of this path, we need to use the Pythagorean theorem to find the distance between the two points on the surface of the cone.
The height of the cone is 24cm, and the distance between the two points on the circumference is 12pi cm. Using the Pythagorean theorem, we can calculate the length of the shortest path as the square root of (12pi)^2 + 24^2 = 12pi cm + 576 = √(144π^2+ 576)cm=44.69 cm.
So, the length of the shortest path is √(144*π^2+ 576)cm = 44.69cm

The 95% confidence interval for the true proportion of first-year students who intend on majoring in liberal arts is estimated to be between 0.58 and 0.66.
To calculate the 95% confidence interval for the true proportion of first-year students who intend on majoring in liberal arts, we need to calculate the point estimate and margin of error. The point estimate is the proportion of first-year students who stated they intend on majoring in liberal arts
(62/100 = 0.62).
The margin of error is 1.96 times the standard error
(SE = √(p(1-p)/n) = √(0.62(1-0.62)/100) = 0.04).
The lower bound of the 95% confidence interval is the point estimate minus the margin of error
(0.62 - 0.04 = 0.58).
The upper bound of the 95% confidence interval is the point estimate plus the margin of error
(0.62 + 0.04 = 0.66).
Therefore, the 95% confidence interval for the true proportion of first-year students who intend on majoring in liberal arts is estimated to be between 0.58 and 0.66.

a card is drawn at random from a standard $52$-card deck. what is the probability that it is an odd number ($3,$ $5,$ $7,$ $9$) or a $\spadesuit$ (or both)?
The probability that the randomly drawn card is an odd number (3, 5, 7, 9) or of spade suit is 25/52.
Now, According to the question:
We are informed that a card is drawn at random from a standard 52-card deck.
We are asked the probability that the randomly drawn card is an odd number (3, 5, 7, 9) or of spade suit.
We assume the event of drawing an odd card from the random pick to be A, and the event of drawing a card of spade suit to be B.
The number of outcomes favorable to event A = 16 {4 odd cards of each of the 4 suits, that is, 4×4 = 16}.
The total number of possible outcomes = 52 {The number of cards in the deck}.
Therefore, the probability of event A, P(A) = 16/52.
The number of outcomes favorable to event B = 13 {The 13 cards of spade suit}.
The total number of possible outcomes = 52 {The number of cards in the deck}.
Therefore, the probability of event B, P(B) = 13/52.
The number of outcomes favorable to events A and B both = 4 {4 odd cards of the spade suit}.
The total number of possible outcomes = 52 {The number of cards in the deck}.
Therefore, the probability of events A and B both, P(A ∩ B) = 4/52.
The probability that the randomly drawn card is an odd number or of spade suit is represented by P(A ∪ B), which is calculated by the formula:
P(A ∪ B) = P(A) + P(B) - P(A ∩ B) = 16/52 + 13/52 - 4/52 = 25/52.
Hence, the probability that the randomly drawn card is an odd number (3, 5, 7, 9) or of spade suit is 25/52.

Answer:
"going from the point 0 comma negative 120 through the point 2 comma negative 100"
Step-by-step explanation:
Let y be the total income from the homecoming dance, and x the number of students who purchase tickets (at $10 each). We are told that it costs $120 for the decorations.
The income from ticket sales would be:
1) the number of tickets sold times $10/ticket, or $10
2) Less the expenses of decorating (-$120)
We can write the total income as:
y = $10x - $120
The graph of this function would be a straight line that has a y-intercept of -$120. Before any ticket is sold, the cost of decorations must be considered. If no tickets are sold (x=0), the total income is -$120.
Using the equation, we can calculate the income when 2 tickets are sold (x=2):
y = $10x - $120
y = $10*(2) - $120 [two tickets sold]
y = -$100
Summary
y = $10x - $120
(0,-$120)
(2,-$100)
This matches the statement "going from the point 0 comma negative 120 through the point 2 comma negative 100" provided in the answer options.

Step-by-step explanation:
1.
equilateral triangle. all sides and also all angles are equal.
the sum of all angles in a triangle is always 180°.
so,
6x = 180/3 = 60°
x = 10
2.
all 3 angles are equal, so, also all 3 sides are equal.
6x - 5 = 5x
x - 5 = 0
x = 5
3.
again, all 3 angles are equal.
3x = 180/3 = 60
x = 20
4.
the 2 sides are marked as equally long.
4x = 40
x = 10
5.
isoceles triangle with 60° angle in top, that means it is again an equilateral triangle.
3x + 8 = 4x - 4
8 = x - 4
12 = x
6.
again all angles are equal.
4x = 60
x = 15
Given the function f(x)=3x^5 and g(x)=7*4^x, Which statement is true

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.
What is a function?The process of evaluating a function is typically straightforward when we have the function in the form of a formula. For instance, it is possible to evaluate the function f(x)=53x2 by first squaring the input number, multiplying by 3, and then subtracting the result from 5.
The algebraic expression should often take one of the following forms: addition, subtraction, multiplication, or division. Bring the variable to the left and the remaining values to the right to determine the value of x.
To determine the outcome, simplify the values. The abscissa is the x value of the point (x, y). It shows how far a point is from the origin or from the x-axis' horizontal axis.

what’s the answer plwase and thank you i’m so stuck i just want a good grade.
as you already know, to get the inverse of any expression we start off by doing a quick switcheroo on the variables and then solving for "y", let's do so.
[tex]\stackrel{f(x)}{y}~~ = ~~10(\sqrt[7]{x}+9)\hspace{5em}\stackrel{\textit{quick switcheroo}}{x~~ = ~~10(\sqrt[7]{y}+9)} \\\\\\ \cfrac{x}{10}=\sqrt[7]{y}+9\implies \cfrac{x}{10}-9=\sqrt[7]{y} \\\\\\ \left( \cfrac{x}{10}-9 \right)^7=(\sqrt[7]{y})^7 \implies \left( \cfrac{x}{10}-9 \right)^7=\stackrel{f^{-1}(x)}{y}[/tex]
Solve the problem. Express your answer to the correct number of significant figures. 6.221 x 7.11 - 13.7
The answer in the correct number of significant figures is 30.5.
What is the significant figure?
Significant figures are the number of digits in a value, often a measurement, that contributes to the degree of accuracy of the value. We start counting significant figures at the first non-zero digit.
We have given,
6.221 × 7.11 − 13.7
first, we determine the product of 6.221 and 7.11 and round the value to a minimum number of significant figures which is "3" since 7.11 has "3" significant figures and 6.221 has "4" significant figures
so Product = 6.221 × 7.11 = 44.2
now we do the subtraction and round the answer to a minimum decimal number
44.2 - 13.7
30.5
Hence, the answer in the correct number of significant figures is 30.5.

What is the condition for a triangle whose two sides are 6cm 8cm then the third side is?
Answer:
10cm
Step-by-step explanation:
Pythagoras
(6×6) + (8×8) = □×□
36 + 64 = 100
square root of 100 = 10
Answer:
Step-by-step explanation:
The condition for a triangle whose two sides are 6cm and 8cm is the triangle should be right angled triangle.
so by this condition,
=> (hypotenuse)^2 = (base)^2 + (perpendicular)^2
=> (hypotenuse)^2 = (6)^2 + (8)^2
=> hypotenuse = 10 cm
so the thisrd side of triangle is 10cm.
for the first three seconds of the day, the arrival rate at the book store is 29 customers per second. the book store is capable of serving 27 customers per second. the last customer's arrives exactly three seconds after the start of the day. assume that the system is empty at the start and that no customer who arrives leaves without being served. 01-05-56 (round your answer to 2 decimal places.) how long will that customers be in the book store (in seconds)?
The last customer will be in the book store for 3.22 seconds.
The solution can be calculated using Little's Law, which states that the average number of people in a system equals the average arrival rate multiplied by the average time spent in the system.
Using this formula, we can calculate the time that the last customer will spend in the book store.
Little's Law: Average number in system = Average arrival rate x Average time in system
Average number in system = 29 customers/second x 3 seconds = 87 customers
Average time in system = 87 customers/27 customers/second = 3.22 seconds
Therefore, the last customer will be in the book store for 3.22 seconds.
