Scott is four more than double the age of Todd. Scott is 56. What is Todd's age?

SSSSS [86.1K]

Answer: 26 years old

Step-by-step explanation:

Since Scott is four more than double the age of Todd, start by taking away four from Scott's age.

56-4=52

Then take half of that because that would be double of Todd's age

52/2=26

Todd is 26 years old.

Analyze the graph of a cannonball launched from the ground with an initial velocity of 144 feet per second. The cannonball reach

MrRissso [65]

We can find that the formula is:
$h(t)=-16t^2 + 144t$

We are told that the cannonball reaches its maximum height at t = 4.5 seconds. To find the maximum height, let's just plug this into the formula:
$h(4.5) = -16(4.5)^2 + 144(4.5) = 324$

The height is 324 feet. We're done!

I really don't understand this I need help

Salsk061 [2.6K]

In looking at it I would guess it is asking which of the points is on the line? To answer that you would have to take each point an plug it into the equation and see if it is true.

3x - 7 = y

A(9,20)
3(9) - 7 = 20
27 - 7 = 20
20 = 20 True - this point is on the line

B(5,0)
3(5) - 7 = 0
15 - 7 = 0
8 = 0 False - this point is not on the line

C(3,2)
3(3) - 7 = 2
9 - 7 = 2
2 = 2 True - this point is on the line

I hope this helps
