Answer:
5^ -8 or 1/ 5^8
Step-by-step explanation:
(5^-2)^4
We know that a^b^c = a^(b*c)
(5^-2)^4 = 5^(-2*4) = 5^(-8)
We know that a^ - b = 1/ a^b
5^ -8 = 1/ 5^8
Answer:
5
Step-by-step explanation:
To find this, we divide the number of dimes by the number of quarters.

X=8
Set up proportions would give you: 10/3x+1 = 22/7x-1
With that in mind, cross multiply, which would give you: 10(7x-1) = 22(3x+1).
Turns into: 70x -10 = 66x+22. Then just solve for x
Answer:
18
Step-by-step explanation:
(3+2)²-7
add the number inside the parentheses
5²-7
the ² above the 5 is called square and that means multiply be him self so:
5*5=25
25-7=18
Answer:
The height = 223.6 ft
Step-by-step explanation:
∵ Initial velocity (u) = 144 ft/sec
∵ t = 2 sec
∵ a = - 32.2 ft/sec²
∵ h = ut + 1/2 at²
∴ h = 144(2) +1/2 (-32.2 × 4) = 288 + 1/2( -128.8) = 223.6 ft
