A ball is thrown from the top row of seats in a stadium. The function h(t)=-16t2+48t+160 gives the height, t, in feet, of the ball t seconds after it is thrown. How long will it be before the ball hits the ground?
Answer:
t = 5 s
Step-by-step explanation:
The function that gives the height in feet of the ball t seconds after it is thrown is :
[tex]h(t)=-16t^2+48t+160[/tex]
We need to find how long will it be before the ball hits the ground. When it hits the ground, its height will be equal to 0.
So,
[tex]-16t^2+48t+160=0[/tex]
We need to solve this equation. When we solve, we get its solution as shown in the figure. We can see that t = -2 s and t = 5 s.
t = -2 s is not possible.
Hence, the ball will hit the ground before 5 seconds.

Anna made and sold x ceramic vases one week. Her profit, P, in dollars is calculated using the formula P = R - C . Where R represents her revenue and C represents her costs. If R = 25x - 0.5x ^ 2 C = 100 + 5x which expression represents her profit in dollars?
Answer:
-0.5x² + 20x + 100
Step-by-step explanation:
Given:
R = 25x - 0.5x²
C = 100 + 5x
P = R - C
Where,
P = profits
R = Revenue
C = Cost
which expression represents her profit in dollars?
P = R - C
R = 25x - 0.5x²
C = 100 + 5x
= 25x - 0.5x² -(-100 + 5x )
= 25x - 0.5x² + 100 - 5x
= -0.5x² + 20x + 100
The expression which represents her profit in dollars is -0.5x² + 20x + 100
5. What is the perimeter of a rectangle with a length of 9x - 4 and a width of 5x+2?
Answer:
14x-2
Step-by-step explanation:
In order to find the perimeter we need to add the length and width together. So adding 5x and 9x gives us 14x. -4+2=-2
The perimeter of a rectangle with a length of 9x - 4 and a width of 5x+2 is, 28x-4
What is the perimeter?Perimeter is a mathematical term, which means total outer boundary of a figure, we define it only for two dimensional figures.
Perimeter = Sum of length of the all the sides
Given that,
length of rectangle = 9x - 4
width of rectangle = 5x+2
As we know,
Perimeter = Sum of length of the all the sides
Perimeter = (9x - 4) + (5x+2) + (5x+2) + (9x - 4)
Perimeter = 28x-4
Hence, The perimeter is 28x-4

8(3 + 8)
8(16 + 64)
Answer:
8(3+8)
Step-by-step explanation:
24+64=88
Now you have to find which expression equals 88.
8(3+64)=8x3+8x64=24+512=536
8(16+56)=8x16+8x56=128+448=576
8(3+8)=8x3+8x8=24+64=88
Therefore, 8(3+8) is correct.

slope =-5, y-intercept =-2
Answer:
y = -5x - 2
Step-by-step explanation:
y = mx + b
m = -5
b = -2
Step-by-step explanation:
I am not completely sure what your question is, but if you want to write an equation, you can just plug in the values for m and b to get y=-5x-2. If you wish to graph it, start at (0,-2) because that is your y-intercept. Next, move up 5 units and to the left 1 unit since the slope is negative. Now you have the point (-1,3). Connect the dots to get the graph.
