(x - 10)² = -12 (y + 4) represents a parabola with a vertical axis of symmetry, vertex at (10, –4), and p = –3 .
What's a vertical parabola?
A vertical parabola has its axis of symmetry at x = h, and the vertex is (h, v). With this information, you can find the focus and directrix. The focus is the distance from the vertex to the focus is 1/(4a), where a can be found in the equation of the parabola (it is the scalar in front of the parentheses).
we know that
If the axis of symmetry is parallel to the y-axis, then we have a vertical parabola
The equation of a vertical parabola is equal to
4p(y - k) = (x - h)²
where
(h,k) is the vertex
In this problem we have
(h,k) = (10, –4)
p= -3
substitute
4*(-3)(y - (-4)) = (x - 10)²
-12 (y + 4) = (x - 10)²
or
(x - 10)² = -12 (y + 4)
Hence , option D is correct.

Tuna can be bought in 12-oz cans for $1.10 each or in 10 oz cans that sell for $0.98 each. Which is a better buy? USE UNIT RATIOS TO ANSWER THIS PROBLEM.
Answer: Option 1
Step-by-step explanation:
I'd say the easiest way would be to find the prize per oz in both options
Option 1: $1.10/12oz = approx 0.092 (so around 9 pennies)
Option 2: $0.98/10oz = 0.098 (also 9 pennies but still slightly more than option 1)
You can check by choosing a random number of oz and multiplying them by the price to see which costs more
ex: 120 oz
option 1 : 10 x 1.10 = $11
option 2: 12 x 0.98 = $11.76

A graphing calculator is recommended. In this problem you are asked to find a function that models a real-life situation and then use the model to answer questions about the situation. Use the guidelines on page 237 to help you. A box with an open top is to be constructed from a rectangular piece of cardboard with dimensions 12 in, by 20 in. by cutting out equal squares of side x at eech corner and then folding up the sides (see the figure). 20 in. 12 in. (a) Find a function that models the volume V of the box. (b) Find the values of x for which the volume is greater than 230 in2. (Rgund your answers to three decimal places. Enter your answer using interval notation) (c) Find the largest volume that such a box can have. (Round your answer to three decimal places) in2
A function modeling the volume of the box can be found, and the values of x for which the volume is greater than 230 in2 are x = [-2.636, 2.636]. The largest volume is 480 in2, which is achieved when x = 5.
A function that models the volume V of the box can be found by subtracting four [tex]x2[/tex]from both the length and the width, and then multiplying the result to get the volume:
V = [tex](12 - 4x2)(20 - 4x2)[/tex]
To find the values of x for which the volume is greater than 230 in2, we can solve the equation
V = [tex](12 - 4x2)(20 - 4x2) = 230[/tex] for x.
This gives x values of ±2.636
Thus, the values of x for which the volume is greater than 230 in2 are x = [[tex]-2.636, 2.636[/tex]].
The largest volume that such a box can have is 480 in2, which is obtained when x is equal to the length or width divided by two. This occurs when x = 10/2 = 5. Thus, the largest volume that such a box can have is 480 in2.

Justin jogged for four days in a row. On the second day, he jogged 75% of the distance he jogged the first day. On the third day, he jogged 1.5 miles, more than the distance he jogged the first day. If Justin jogged a total distance of 9.25 miles, how many miles did he jogged on the fourth day?
On solving the prοvided question, we can say that 4.75 miles were ran on day four.
What is equation?A mathematical equation is a formula that jοins two statements and uses the equal symbol (=) tο indicate equality. A mathematical statement that establishes the equality of twο mathematical expressions is known as an equatiοn in algebra.
Fοr instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences οn either side of a letter is described by a mathematical formula. Often, there is only οne variable, which alsο serves as the symbol. for instance, 2x – 4 = 2.
On day one, Justin ran two miles.
He ran two miles on the second day, or 75% of it. Divide by 100 and multiply by 75 to get the percentage of two miles that is 75%.
On the secοnd day, I ran 1.5 miles, or 2 / 100, or 0.02 x 75. (I've run 3.5 miles so far)
He ran 1.5 miles further on the third day than the previous one:
1.5 + 1.5 = 3 (6.5 miles jogged sο far) (6.5 miles jogged so far)
The total number of miles run was 9.25, thus tο find the solution, we must subtract 6.5 from 9.25.
4.75 miles were ran οn day four, or 9.25 minus 6.5.

F(x)=|x| is transformed to g(x)=|x|+4 what transformation happens from f(x) to g(x)
Step-by-step explanation:
The transformation from the function f(x) = |x| to the function g(x) = |x| + 4 can be thought of as a vertical shift upward by 4 units. The shape of the absolute value function remains unchanged, but the entire graph is shifted upward along the y-axis by 4 units. This can be visualized by observing that for any value of x, g(x) = f(x) + 4.
So, the transformation of f(x) to g(x) is a vertical shift upward by 4 units

Patrick and Brooklyn are making decisions about their bank accounts. Patrick wants to deposit $300 as a principal amount with an interest of 3% compounded quarterly Brooklyn
wants to deposit $300 as the principal amount, with an interest of 5% compounded monthly Explain which method results in more money after 2 years Show all work
Answer:
To compare the amount of money that Patrick and Brooklyn would have after 2 years, we need to calculate the interest earned using each of their methods.
For Patrick, who deposited $300 with an interest rate of 3% compounded quarterly, the formula to calculate the amount after 2 years (8 quarters) is:
A = P(1 + r/n)^(nt)
Where:
P = principal amount ($300)
r = interest rate (3%)
n = number of times compounded per year (4)
t = time in years (2)
Substituting the values into the formula:
A = $300(1 + 0.03/4)^(4 * 2)
A = $300(1.0075)^8
A = $300 * 1.06173
A = $318.52
For Brooklyn, who deposited $300 with an interest rate of 5% compounded monthly, the formula to calculate the amount after 2 years (24 months) is:
A = P(1 + r/n)^(nt)
Where:
P = principal amount ($300)
r = interest rate (5%)
n = number of times compounded per year (12)
t = time in years (2)
Substituting the values into the formula:
A = $300(1 + 0.05/12)^(12 * 2)
A = $300(1.00417)^24
A = $300 * 1.09722
A = $328.17
Therefore, after 2 years, Brooklyn would have $328.17, which is more money than Patrick's $318.52.

The acceleration was -26.04 m/s².
What are Equations of Motion?Equations of motion are a set of equations which describes the basic motion concepts like velocity, position, time and acceleration.
There are mainly three equations of motion.
v = u + at
s = ut + [tex]\frac{1}{2}[/tex] at²
v² = u² + 2as
v is the final velocity, u is the initial velocity, a is the acceleration, t is the time and s is the displacement.
Given,
Initial velocity of the motorist, u = 90 km/h = 90 × (5/18) m/s = 25 m/s
Final velocity of the motorist, v = 0 m/s (since the bike stopped)
Stopping distance, s = 12 m
Using the third equation of motion,
v² = u² + 2as
0² = 25² + (2a × 12)
24a = -625
a = -625 / 24 = -26.04 ≈ -26 m/s²

i. What is the person's displacement from the starting point? How did you calculate this? Be sure to round to the nearest hundredth.
ii. From point B, in what direction would the person have to look in order to be looking back at point A (the starting point)? Give your answer as a true bearing calculated to the nearest hundredth of a degree. Explain how you got this answer.
iii. A friend is standing at point A looking at point B. In what direction would that friend be looking? Give your answer as a true bearing calculated to the nearest hundredth of a degree. Explain how you got this answer.
The answers are mentioned below.
What do you mean by Displacement?In physics, displacement is defined as the change in position of an object from its initial position to its final position, measured as a straight line distance in a specific direction. It is a vector quantity, which means it has both magnitude (the distance between the starting and ending points) and direction. Displacement is different from distance, which is the actual length of the path traveled by an object regardless of its starting and ending points.
i. The person's displacement from the starting point can be calculated using the Pythagorean theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. In this case, the person has walked a distance of 500 yards south and 300 yards west, which forms a right triangle. Therefore, the displacement can be calculated as the square root of (500^2 + 300^2) = 583.1 yards (rounded to the nearest hundredth).
ii. To be looking back at point A from point B, the person would have to look in the direction opposite to the direction in which they walked from A to B. Since the person first walked due south and then due west, the direction in which they would have to look to be looking back at point A is north-east. This can be calculated using trigonometry, where the tangent of the angle formed between the line connecting A and B and the due south line is equal to 300/500. Therefore, the angle formed is the arctangent of (300/500) = 31.39 degrees. However, the true bearing is measured from the north and therefore, the true bearing would be 360 - 31.39 = 328.61 degrees (rounded to the nearest hundredth).
iii. If a friend is standing at point A looking at point B, they would be looking in the direction of the line connecting points A and B. To determine the true bearing, we need to find the angle formed between the due north line and the line connecting A and B. This angle can be calculated as the arctangent of (500/300) = 59.04 degrees. However, the true bearing is measured from the north and therefore, the true bearing would be 90 + 59.04 = 149.04 degrees (rounded to the nearest hundredth).

i. The person's displacement from the starting point can be calculated using the Pythagorean theorem, the person has walked a distance of 500 yards south and 300 yards west, which forms a right triangle. Therefore, the displacement can be calculated as the square root of (500² + 300²) = 583.1 yards
What do you mean by Displacement?In physics, displacement is defined as the change in position of an object from its initial position to its final position, measured as a straight line distance in a specific direction. It is a vector quantity, which means it has both magnitude (the distance between the starting and ending points) and direction. Displacement is different from distance, which is the actual length of the path traveled by an object regardless of its starting and ending points.
i. The person's displacement from the starting point can be calculated using the Pythagorean theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. In this case, the person has walked a distance of 500 yards south and 300 yards west, which forms a right triangle.
Therefore, the displacement can be calculated as the
√(500² + 300²)
= 583.1 yards (rounded to the nearest hundredth).

Solve the system by substitution.
y = 5x
y = 4x + 9
Answer:
x=9
Step-by-step explanation:
Since y=5x, you plug it into the other equation's y and it'd look like this 5x=4x+9. Then you subtract 4x on both sides and that would leave you with an x=9.
Write an equation in slope intercept form for the line that passes through the two given points.(-3,4) (3,2)
Answer:
y = -1/3 x + 3
Step-by-step explanation:
To find the equation of the line that passes through the two points (-3,4) and (3,2) in slope-intercept form, we'll first find the slope of the line using the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are the two given points.
Plugging in the given points, we get:
m = (2 - 4) / (3 - (-3)) = -2 / 6 = -1/3
Next, we'll use the point-slope form of a line to find the equation of the line:
y - y1 = m(x - x1)
where (x1, y1) is one of the given points, and m is the slope of the line.
We'll use the first given point, (-3,4), so we have:
y - 4 = -1/3 (x - (-3))
Expanding the right side of the equation, we get:
y - 4 = -1/3 x + 1
Finally, we'll rearrange the equation to get it in slope-intercept form, which is:
y = -1/3 x + b
where b is the y-intercept. To find b, we'll plug in one of the given points and solve for b:
y = -1/3 x + b
4 = -1/3 * (-3) + b
4 = 1 + b
b = 4 - 1
b = 3
So the equation of the line in slope-intercept form is:
y = -1/3 x + 3

Answer:
100π - 192 or 122.159....
Step-by-step explanation:
In order to find the diameter we much first split the rectangle diagonally and find the hypotenuse using Pythagorean theorem.
a^2 + b^2 = c^2
16^2 + 12^2 = c^2
400 = c^2
c = 20
If the diameter of the rectangle is 20, the radius is just half of that which is 10. Then you just need to a do a basic calculation for area of a circle and then subtract out the area of the rectangle.
Area of circle = πr^2 = π(10^2) = 100π (keeping it in exact value since π is infinite)
Area of rectangle = lw = (16)(12) = 192
Area of shaded area = 100π - 192 (exact) = 122.159 (estimate)
