Answer:
Step-by-step explanation:
11L - 42 = 4L
7L = 42
L = 6
Dr/dt= 8cmM-¹
dA/dt = ?
but A= πr²
so dA/dr =2πr
but recall
dA/dt = dA/dr • dr/dt
dA/dt = 2πr • 8cmM-¹
dA/dt = 2×π×39 ×8 = 624cm²M-1
The answer is 0.2
Hope this helps
Answer:
x = 5/4
Step-by-step explanation:
By combining like terms, you get 8x = 10.
Divide the 8 on both sides of the equation.
x = 10/8
This, however, can be simplified by dividing by 2. This ultimately gives us 5/4.
Answer:
log x^13.
Step-by-step explanation:
Using the laws of logarithms
a log b = log b^a and log a + log b = log ab:
3 log x^2 + 7 log x
= log (x^2)^3 + log x^7
= log x^6 + log x^7
= log (x^6*x^7)
= log x^13.
