Answer:
The correct answer is:
D=
Step-by-step explanation:
We have the equation
h = D^2N /2.5 (1)
We have to clear the equation for (1). Multiplying (1) by 2.5
2.5 h = D^2 N (2)
Dividing (2) by N,
= D^2 (3)
By taking the square root of (3), finally we have
= D
Hi there!
Answer:
-14.98%(or -15%).
Step-by-step explanation:
1)To find the percent decrease,all you have to do is minus the original number from the decreased amount so:
1435-1220= 215
2)Then you divide this answer by the original number again so:
215÷1435= 0.1498
3)Then you times the decimal by 100 so:
0.1489x100= -14.98%(or -15%).
Hope this helps!
Answer:
r(-2) = -5 , r(0) = -7 , r(5) = -12
Step-by-step explanation:
Plug in the numbers for x and then solve. : )
r(-2) = - (-2) - 7
r(-2) = 2 -7
r(-2) = -5
r(0)= -0 -7
r(0)=0-7
r(0) = -7
r(5) = -5 - 7
r(5) = -12
