If you let x be the number to get 8 more you add so it would be x+8
Answer:
No it is still 11 feet from the water at 2 seconds
2.1651 seconds is when it will hit the water
Step-by-step explanation:
h(t) = -16 t^2 +75
This is the formula for the distance
The -16t^2 is due to gravity and the 75 is the height above the bridge
We want to know the height a t =2
h(2) = -16 (2)^2 +75
h(2) =-64 +75
h(2) = 11
The rock will be 11 ft above the water
When will the rock hit the water
h = 0
0 = -16 t^2 +75
Subtract 75 from each side
-75 = -16t^2 +75-75
-75 = -16t^2
Divide by -16
-75/-16 = -16t^2 /-16
75/16 = t^2
Take the square root of each side. We only take the positive square root since time must be positive
sqrt(75/16) =t
5/4 sqrt(3) = t
2.1651 seconds = t
Answer:
My payment for the 7th study session will be 78125 dimes.
Step-by-step explanation:
My friend will pay me 5 dimes for helping him study for the first time.
Now, I agree to help him if he multiplies my payment by 5 for each study session.
So, he will pay 25 dimes for the 2nd study session, 125 dimes for the 3rd study session and so on.
Hence, my payment in each study session increases in geometric progression as follows:
5, 25, 125, ........ so on.
So, the 7th term of this series indicates the number of dimes that my friend pays me after the 7th study session.
This is a G.P. series having first term 5 and common ratio 5, then the 7th term will be 
Therefore, my payment for the 7th study session will be 78125 dimes. (Answer)
That expression can be written as
1 + 1·x
Answer:
The height of the pack of gum is 48cm
Step-by-step explanation:
The base solution is Volume = length x width x height, or V=lwh for short.
We can first put our numbers into the base equation.
48=(8)(2)h
Then we would follow as many steps of BEDMAS as possible
48=16h
Since we need to get the variable (h) by itself, we would subtract any unnecessary numbers from the right side of the equation. Since we remove numbers from one side of the equation, we always have to do the same to the other side of the equation.
48-16=16-16h
You're then left with your answer.
32=h
