Amaya is standing 30 ft from a volleyball net. The net is 8 ft high. Amaya serves the ball. The path of the ball is modeled by the equation y=-0.02(x-18)^2+12, where x is the ball's horizontal distance in feet from Amaya's position and y is the distance in feet from the ground to the ball. a. How far away is the ball from Amaya when it is at its maximum height? Explain. b. Describe how you would find the ball's height when it crosses the net at x=30. a. How far away is the ball from Amaya when it is at its maximum height? Explain. The ball is nothing ft away from Amaya when it is at its maximum height. Use the ▼ y-coordinate x-coordinate of the vertex.
Answers
Answer:
a) 30feet
b) 9.12feet
Step-by-step explanation:
a) Given the path of the ball is modeled by the equation y=-0.02(x-18)²+12, where;
x is the ball's horizontal distance in feet from Amaya's position
y is the distance in feet from the ground to the ball.
The ball will be at the maximum height when dy/dx = 0
Differentiate the function:
dy/dx = 2(-0.02)(x-18)^(2-1)+0
dy/dx = -0.04(x-18)
Equate the resulting expression to zero and find x as shown;
-0.04(x-18) = 0
Open the parentheses
-0.04x+0.04(18) = 0
-0.04x+0.72 =0
-0.04x = -0.72
x = -0.72/-0.04
x = 18ft
Hence the ball is 18ft away from Amaya when it is at its maximum height
b) To get the balls height y when x = 30, we will substitute x = 30 into the equation given and calculate the value of y as shown:
y=-0.02(x-18)²+12
y = -0.02(30-18)²+12
y= -0.02(12)²+12
y = -0.02(144)+12
y = -2.88+12
y = 9.12 feet
Hence the Ball's height is 9.12feet when it crosses the net at x = 30.

Answers
Answer:
z = 40° (V. O. A)
Now find x
40 + 25 + x = 180(A. S. P)
65 + x = 180
x = 180 - 65
x = 115°
Now find y
x = y (V. O. A)
Y = 115°
So angles are
X = 115°
Y = 115°
Z = 40°

Identify an equation in point-slope form for the line perpendicular to
y=-1x +11 that passes through (4, -8).
O A. y +8 = 2(x-4)
B. y - 4 = 2(x+8)
O C. y+8 = {(x-
-4)
O D. 7-8 = {(x + 4)
Answers
Answer:
C
Step-by-step explanation:
Perpendicular lines have the exact opposite slope of the other equation.
So the slope will be x or 1x. Plug in
-8 = 1(4) + b (b represents y-intercept) like y=mx+b
-8 = 4 + b (subtract 4 on both sides)
-12 = b
The equation is y = x - 12
C
solve
y + 8 = x - 4 (subtract 8 on both sides)
y = x - 12

Cherries are on sale at the grocery store at a price of $5 for 2 pounds. Oscar buys 3
pounds. If he is charged the sale price for the cherries, how much will Oscar pay?
Answers
Answer:
$7.5 = 3 pounds
Step-by-step explanation:
1. If $5 is equal to 2 pounds of cherries, you want to find what 1 pound of cherries cost. You should divided 5 by 2 and 2 by 2 to find what 1 pound of cherries cot.
2. That means that 1 pound of cherries cost $2.5.
3. Now we want to find how much money 3 pounds cost, so you should multiply the 2.5 and the 1 by 3.
4. Now that gets you to $7.5 for 3 pounds of cherries.s

Tamar used the algebraic method to convert the repeating decimal number to 2.45 to a fraction. Her first two steps are shown below. Step 1: x=2.45. Step 2: 100x=245.45. What should be Tamar’s next step
Answers
Answer:
see explanation
Step-by-step explanation:
Given the 2 equations
x = 2.4545... → (1)
100x = 245.4545... → (2)
Subtract (1) from (2) eliminating the repeating decimal
99x = 243 ( divide both sides by 99 )
x = [tex]\frac{243}{99}[/tex]

2,3,5,7,11,13 conjecture
Answers
Answer:
The primes up to 50 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43 and 47. The sequence of gaps—the differences between each prime and the next—is 1, 2, 2, 4, 2, 4, 2, 4, 6, 2, 6, 4, 2 and 4. The number 1 appears only once because all primes except for 2 are odd. The rest of the gaps are even numbers.
The conjecture which could be inferred from the sequence is that it is a list of prime numbers.
From the sequence given : 2, 3, 5, 7, 11, 13
All values in the sequence are prime numbers.
Prime numbers are numbers which have only two divisors which are 1 and the number itself.
Divisors of :
2 = 1 and 2
3 = 1 and 3
5 = 1 and 5
7 = 1 and 7
11 = 1 and 11
13 = 1 and 13
Hence, the conjecture which could be inferred from the sequence is that, the numbers are prime numbers.
