The graph state that the initial point is (6.9), and the terminal point is (2,1). The vertex of the parabola is (3,0). Arrows along the parabola to indicate motion right to left.
What is the parametric equations about?Let take x = 4 - t =t = 4 - x as equation (1)
And y = (t - 1)^2 as equation (2)
Then input equation (1) into equation (2)
y = ( 4 - x - 1)^2
y = ( 3 - x)^2
y = ( x - 3)^2
So therefore, y = a ( x -3)^2 + 0
It can be written as y = a(x - h)^2 + k
Where, a = 1
The vertex known to be (h, k) will be = (3,0).
The starting point is if t = -2
Therefore, x = (4 - -2) = 6
y = (-2 - 1)^2 = (-3)^2 = 9
So x, y = (6,9).
Note that if t = 2
Then x = (4 - 2) = 2
y = (2 - 1)^2 = 1^2
= 1
Therefore, x, y =(2, 1).
Therefore, The graph of the parametric equations state that the initial point is (6.9), and the terminal point is (2,1). The vertex of the parabola is (3,0). Arrows along the parabola to indicate motion right to left.

A model rocket is launched 25 feet from you. When the rocket is at height h, the
distance d between you and the rocket is given by d = √216 +h2 where h and d
are measured in feet. What is the rocket's height when the distance between you and
the rocket is 100 feet? Round to 3 decimal places
Question 6
5 pts
The rocket's height when the distance between you and the rocket is 100 feet is 98.9 feet
How to determine the rock's height?The function is given as:
d = √216 +h²
At a distance of 100 feet, it means that:
d = 100
So, we have:
√216 +h² = 100
Take the square of both sides
216 +h² = 10000
Subtract 216 from both sides
h²= 9784
Take the square root of both sides
h = 98.9
Hence, the rocket's height when the distance between you and the rocket is 100 feet is 98.9 feet

Keesha buys grapes and bananas. These bills and coins represent the cost of each item. How much did Keesha spend in all? Enter your answer in the box.
The total amount of money spent by Keesha to buy grapes and bananas is equal to $6.38.
How much did Keesha spend in all?
Based on the value of the bills and coins which represent the cost of each item, we would determine the total amount of money spent by Keesha to buy grapes and bananas.
For the grapes, we have:
Cost of grapes = 5 + (1 × 0.25) + (2 × 0.1) + 0.05
Cost of grapes = 5 + 0.25 + 0.2 + 0.05
Cost of grapes = $5.5.
For the bananas, we have:
Cost of bananas = (3 × 0.25) + 0.1 + (3 × 0.01)
Cost of bananas = 0.75 + 0.1 + 0.03
Cost of bananas = $0.88.
Total cost = 5.5 + 0.88
Total cost = $6.38.

A bicycle company is designing women's bicycle frames. The frames can accommodate any woman taller than 54.5 inches. Given that the heights of adult American women are normally distributed, with a mean of 65 inches and a standard deviation of 3.5 inches, what percentage of American women CANNOT use the bicycles designed by this company
Using the normal distribution, it is found that 0.13% of American women CAN NOT use the bicycles designed by this company.
What is Normal Probability Distribution?The z-score of a measure X of a normally distributed variable with mean and standard deviation is given by:
[tex]z=\dfrac{x-\mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean.Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation are given, respectively, by:
[tex]\mu = 65\ \ \sigma= 3.5[/tex]
The proportion of women that cannot use the bikes(smaller than 54.5 inches) is the p-value of Z when X = 54.5, hence:
[tex]z=\dfrac{x-\mu}{\sigma}[/tex]
[tex]z = \dfrac{54.5-65}{3.5}[/tex]
Z = -3
Z = -3 has a p-value of 0.0013.
0.0013 = 0.13% of American women CAN NOT use the bicycles designed by this company.

Use the equation of y = 1.5x +5 to predict the amount of milk needed for a 17-pound goat and a 55-pound goat
The amount of milk needed for a 17-pound goat and a 55-pound goat are 55 and 87.5 cubic units, respectively
How to determine the amount of milk?The equation is given as:
y =1.5x + 5
For a 17-pound goat, we have:
x = 17
This gives
y =1.5 * 17 + 5
y = 30.5
For a 55-pound goat, we have:
x = 55
This gives
y = 1.5 * 55 + 5
y = 87.5

9(w – 4) – 7w = 5(3w – 2)
Answer:
-2 =w
Step-by-step explanation:
9(w – 4) – 7w = 5(3w – 2)
The first step is to distribute
9w -36 - 7w = 15w -10
Combine like terms
2w -36 = 15w -10
Subtract 2w from each side
2w -36 -2w = 15w-10-2w
-36 = 13w -10
Add 10 to each side
-36+10 =13w-10+1-
-26 = 13w
Divide by 13
-26/13 =13w/13
-2 =w
if the area of a square is 32ft how long is the diagonal?
Answer: 8
Step-by-step explanation:
To find the diagonal, we need to use two formulas:
Area of a square: [tex]A = s^{2}[/tex] (Area = side * side)
Pythagorean Theorem: [tex]a^{2} +b^{2} =c^{2}[/tex]
Since every side of a square is the same:
[tex]a^2 = b^2\\a = b = \sqrt{32} \\a^{2} = 32\\b^2 = 32[/tex]
Our equation:
[tex]32 + 32 = c^2\\64 = c^2\\8 = c[/tex]

The correct answer is option A. Which is the solution of the given equation will be (15,15).
What is an equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Given equations are solved as:-
a - 1.2b = -3 or a = -3 + 1.2b
0.2a + 0.6b = 12
Put the value of a from equation 1 to the equation second.
0.2 ( -3 + 1.2 b) + 0.6b = 12
-0.6 + 0.24b + 0.6b = 12
0.84b = 12 + 0.6
0.84 b = 12.06
b = 15
Put the value of b in the first equation to find the value of a.
a = 1.2b - 3
a = (1.2 x 15) - 3
a = 15
Therefore the correct answer is option A. Which is the solution of the given equation will be (15,15).
