Answer:
A G.P is a sequence of numbers such that the ratio of any two consecutive terms is a constant, called the common ratio. Given the first term (3) and the common ratio (0.25) of the G.P, we can find the sum of the first 5 terms using the formula:
S_n = a(1 - r^n) / (1 - r)
Where:
S_n is the sum of the first n terms of the G.P.
a is the first term of the G.P.
r is the common ratio of the G.P.
n is the number of terms in the sum.
So, to find the sum of the first 5 terms of the G.P, we can substitute the given values into the formula:
S_5 = 3(1 - (0.25)^5) / (1 - 0.25)
S_5 = 3(1 - (0.25)^5) / (1 - 0.25) = 3(1 - 0.25^5) / (1 - 0.25) = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75
S_5 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75
S_5 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.75 = 3(1 - 0.25^5) / 0.

Square ABCD has a diagonal AC with vertices A(-2, 1) and C(2, 4). Find the coordinates of the remaining vertices. Express your answers as decimals, if necessary.
The coordinates are ( , ) and ( , )
Answer: The diagonal AC of a square bisects the square and the midpoint of the diagonal is the center of the square. Since the center of the square is the midpoint of the diagonal, we can find the midpoint of AC by averaging the x-coordinates and y-coordinates of A and C.
The coordinates of the center of the square is ( (2+(-2))/2 , (4+1)/2) = (0, 2.5)
Since a square is a special case of rectangle, which means all sides are equal, the length of the side of the square is the distance between A and C.
Using the distance formula, we can find the length of the side of the square:
d = sqrt( (2-(-2))^2 + (4-1)^2 ) = sqrt(4^2 + 3^2) = sqrt(16+9) = sqrt(25) = 5
The coordinates of the vertex D can be found by subtracting half of the side length from x and y coordinates of the center point.
D(0-5/2, 2.5 - 5/2) = (-2.5, 0.5)
The coordinates of the vertex B can be found by adding half of the side length from x and y coordinates of the center point.
B(0+5/2, 2.5 + 5/2) = (2.5, 5.5)
So the remaining vertices are (2.5, 5.5) and (-2.5, 0.5)

If you decide to select walking at a normal pace as your only physical daily activity, what would be the rate at
which you will be burning calories? Show how you calculated that rate
A 140-pound person will typically burn 4 calories per mile of walking at a rate of 3 miles per hour.
Do you burn the same amount of calories walking as running?Walking at a pace of 3 miles per hour results in an average calorie burn of 4 for a 140-pound person. This person would therefore burn around 112 calories in a period of 30 minutes. On the other hand, a 200-pound person burns roughly 5 calories per minute, or 159 calories every 30 minutes.
An average walking speed of 3 miles per hour (or 120 steps per minute) is recommended for health reasons. That is a mile that takes 20 minutes. You must increase your pace to 4 miles per hour (135 steps per minute), or a 15-minute mile, to walk for weight loss.
Walking and running have about equal calorie burn rates per minute. Walking at 3.5 mph for 40 minutes for a 160-pound person would take 40 minutes.

In the equation for the exponential function, f ( x ) = P ( 1 + r ) ^ x, how do we find r (rate of change) algebraically?
Answer:
[tex]r=\left(\dfrac{y}{P}\right)^{\frac{1}{x}}-1[/tex]
Step-by-step explanation:
Given exponential function:
[tex]f(x)=P(1+r)^x[/tex]
Replace f(x) with y:
[tex]y=P(1+r)^x[/tex]
Divide both sides by P:
[tex]\dfrac{y}{P}=(1+r)^x[/tex]
Take natural logs of both sides:
[tex]\ln \left(\dfrac{y}{P}\right)=\ln (1+r)^x[/tex]
[tex]\textsf{Apply the power law}: \quad \ln x^n=n \ln x[/tex]
[tex]\ln \left(\dfrac{y}{P}\right)=x \ln (1+r)[/tex]
Divide both sides by x:
[tex]\dfrac{1}{x}\ln \left(\dfrac{y}{P}\right)=\ln (1+r)[/tex]
[tex]\textsf{Apply the power law}: \quad n \ln x=\ln x^n[/tex]
[tex]\ln \left(\dfrac{y}{P}\right)^{\frac{1}{x}}=\ln (1+r)[/tex]
Raise both sides to power of e:
[tex]\large\text{$e^{\ln \left(\frac{y}{P}\right)^{\frac{1}{x}}}=e^{\ln (1+r)}$}[/tex]
[tex]\textsf{Apply the power law}: \quad e^{\ln x}=x[/tex]
[tex]\left(\dfrac{y}{P}\right)^{\frac{1}{x}}=1+r[/tex]
Subtract 1 from both sides:
[tex]\left(\dfrac{y}{P}\right)^{\frac{1}{x}}-1=r[/tex]
Therefore, the equation to find r is:

How do you find the perimeter?The circumference of a shape is known as its perimeter. The lengths of all four sides must be added in order to get a rectangle's or square's perimeter.
The total length of all a polygon's sides is its perimeter. The polygon's sides are PT, TS, SR, RQ, and QP. We apply the distance formula to get a side's length:
d =[tex]\sqrt{(x2-x1)^{2}+(y2-y1)^{2} }[/tex]
There are points that correspond to each vertex in the polygon:
P (-2,11)
T (8, 7)
S (1, 7)
R (2, 0)
Q (-4,5)
So, using the distance formula and the vertex positions of side PT, we can determine its length: The total length of all a polygon's sides is its perimeter. The polygon's sides are PT, TS, SR, RQ, and QP. We apply the distance formula to get a side's length:
d =[tex]\sqrt{(x2-x1)^{2}+(y2-y1)\x^{2} }[/tex] ≤ b r/≥ d=[tex]\sqrt{(8-(-2)^{2})+(7-11)^{2} }[/tex] ≤b r/≥

There are points that correspond to each vertex in the polygon:
P (-2,11)
T (8, 7)

Find the area under the standard normal curve to the right of z = 3.15.
STEP BY STEP SOLUTION REQUIRED
The area under the standard normal curve to the right of Z (3.15) = 0.0008
The total area under the standard normal curve happens to be 1 which is divided between two parts having an area under the curve = 0.5 on each side.
I.e. from 0 to the right side, the area under the curve = 0.5
Similarly, from 0 to the left side, the area under the curve = 0.5
Now, from the standard normal table,
{the table is given in the attachment}
The area under the curve for the value of Z (3.15) = 0.4992
{This value is the area under the curve from 0 to Z (=3.15)}

He would need to sell $
to reach his needed monthly income needs.
The salesman needs to sell $25937.5 to reach his needed monthly income needs.
What is commission?Commission, also known as sales commission, is a payment given to employees based on the sales they make.
Given that, A local salesman receives a base salary of $925 monthly. He also receives a commission of 8% on all sales over $1250.
Monthly salary = fixed part + commission part
The fixed salary is $925.
The commission part is 8% on all sales over $1250
Let x = amount of sales, and x must be greater than $1250.
Then, the amount of sales over $1250 is x - 1250.
He earns 8% on that amount, so the commission part is 8%(x - 1250),
or 0.08(x - 1250).
Monthly salary = fixed part + commission part
Monthly salary = 925 + 0.08(x - 1250)
925 + 0.08(x - 1250) = 2900

Answer: 48 square inches
Step-by-step explanation:
To find the area of an irregular shape, we first break the shape into common shapes. Then we find the area of each shape and add them. For example, if an irregular polygon is made up of a square and a triangle, then: Area of irregular polygon = Area of Square + Area of Triangle.
area of triangle L x W = 6x4=24
area of rectangle LxW =6x4=24
24+24=48

Answer:
A represents f(x) and B represents g(x)
Step-by-step explanation:
choose a value for x, substitute , say x = 1 into both f(x) and g(x) , then check the values obtained on the graph.
f(x) = 100 × [tex](\frac{3}{5}) ^{1}[/tex] = 100 × [tex]\frac{3}{5}[/tex] = 20 × 3 = 60
thus (1, 60 ) is a point on the graph of f(x)
the point (1, 60 ) is on graph A
g(x) = 100 × [tex](\frac{2}{5}) ^{1}[/tex] = 100 × [tex]\frac{2}{5}[/tex] = 20 × 2 = 40
thus (1, 40 ) is a point on the graph of g(x)
the point (1, 40 ) is on graph B

Step-by-step explanation:
[tex]\frac{30x^{3}y^{2} }{42x^{7} y^{-8} }[/tex] to make [tex]y^{-8}[/tex] positive we need to put it in the numerator (top)
[tex]\frac{30x^{3}y^{2}y^{8} }{42x^{7} }[/tex] Now I am going to write it in expanded form
[tex]\frac{2x3x5xxxyyyyyyyyyyyy}{2x3x7xxxxxxx}[/tex] If we cross out what we have on the bottom and the top, we will be left with our answer simplified.

Answer:
95 6/7
Step-by-step explanation:
The perimeter can be found by adding the length and width together and then multiplying the sum by 2.
Perimeter = 2(L + W)
Where L is the length and W is the width.
So, using the given measurements:
Perimeter = 2(33 5/7+ 14 3/14) = 94 26/14
94 26/14 -> 95 12/14 -> 95 6/7
Answer:
The perimeter is [tex]95\frac{6}{7}[/tex] inches.
Step-by-step explanation:
The formula for the perimeter of a rectangle is
[tex]P=2L+2W[/tex]
We are given the length and the width. Lets evaluate the perimeter.
First lets convert the length and width to an improper fraction.
Length: [tex]33\frac{5}{7}[/tex]
To write 33 as a fraction with a common denominator, multiply by [tex]\frac{7}{7}[/tex]. Then simplify.
[tex]\frac{33*7}{7} +\frac{5}{7}[/tex]
[tex]\frac{231}{7} +\frac{5}{7}[/tex]
[tex]\frac{231+5}{7}[/tex]
[tex]\frac{236}{7}[/tex]
Width:
To write 14 as a fraction with a common denominator, multiply by [tex]\frac{14}{14}[/tex]. Then simplify.
[tex]\frac{14*14}{14} +\frac{3}{14}[/tex]
[tex]\frac{196}{14} +\frac{3}{14}[/tex]
[tex]\frac{196+3}{14}[/tex]
[tex]\frac{199}{14}[/tex]
Lets enter the 2 fractions into the perimeter equation.
[tex]P=(2*\frac{236}{7} )+(2*\frac{199}{14} )[/tex]
Simplify each term.
[tex]P=\frac{2*236}{7} +2*\frac{199}{14}[/tex]
[tex]P=\frac{472}{7} +2*\frac{199}{14}[/tex]
Factor 2 out of 14.
[tex]P=\frac{472}{7} +2*\frac{199}{2(7)}[/tex]
Cancel the common factor of 2.
[tex]P=\frac{472}{7} +\frac{199}{7}[/tex]
Combine the numerators over the common denominator.
[tex]P=\frac{472+199}{7}[/tex]
[tex]P=\frac{671}{7}[/tex]
[tex]P=95\frac{6}{7}[/tex]

What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
Anderson multiplies two rational expressions with the given results.
His error is the inequivalent can't be canceled out.
The two rational expressions are given in the question, as follows:
(x² - 16)/(x² - 8x + 16) × (x + 1)/(x² + 2x + 1)
(x² - 4²)/(x² - 2 × 4 × x + 4² ) × (x + 1)/(x² + 2 × 1 × x + 1²)
(x + 4)(x - 4)/(x - 4)² × (x + 1)/(x + 1)²
(x + 4)/(x - 4)(x + 1)
Thus, the required correct product is (x + 4)/(x - 4)(x + 1).
