Answer:
50/b in
Step-by-step explanation:
Use the area formula A = (1/2)(base)(height).
Here the area A is given and is 25 in^2; the base is not given, so use 'b.'
Then, since A = (1/2)(base)(height),
(height) = 2A/(base) = 2(25 in^2)/b = 50/b in
1 unit = 2.5 feet.
225/2.5 = 90 feet
40/2.5 = 16 feet
Therefore, 90x16, or vice versa, 16x90. =^)
Answer:
-4m/s²
Step-by-step explanation:
<u>Given</u><u> </u><u>Equation</u><u> of</u><u> </u><u>velocity</u><u> </u><u>:</u><u>-</u><u> </u>
<u>Differenciation</u><u> </u><u>of </u><u>first </u><u>order</u><u> </u><u>will </u><u>give </u><u>acclⁿ</u><u> </u><u>:</u><u>-</u><u> </u>
- v = 6t² - 4t -2
- dv/dt = d(6t² - 4t -2)/dt
- dv/dt = 2*6 t¹ - 4*1 t⁰ - 0
- dv/dt = 12t - 4
- a = 12t - 4
<u>At </u><u>t </u><u>=</u><u> </u><u>0</u><u> </u><u>,</u>
- a = 12*0 - 4 m/s²
- a = -4m/s²
Answer:
27/64 or any other equivalent form
Step-by-step explanation:
using quotient rule
f'(x) = =
using quotient rule again
f''(x) =
simplifying to make it easier to plug in
f''(x) =
=
=
=
f''(1) = =
Answer:
x = 5 (please read the step by step explanation)
Step-by-step explanation:
So, I'm just going to solve for x because the instructions aren't too clear. I believe there is supposed to be an image attached to it, but seeing as I don't have that, I'll just solve for x and you can plug in with the values.
15x = 12x + 15
Same to both sides:
3x = 15
Isolate x:
x = 5
Just plug in those values and you'll be good to go! Have a good day!
