<u>Answer:</u>
Two times the difference of a number x and 7 plus 10.
<u>Step-by-step explanation:</u>
We are to write a phrase which matches the following algebraic expression below:
We can see that there is a bracket with a coefficient outside it so we can express it as:
<em>'Two times the difference of a number x and 7'.</em>
While + 10 can be added to it to complete the phrase:
Two times the difference of a number x and 7 plus 10.
If we let V', A', and r' represent the rates of change of the volume, area, and radius of the sphere, we can differentiate equations for V and A in terms of r, then eliminate r' to get an equation for A' in terms of V'.
Then, for the given values, the surface area is increasing at the rate ...
... A' = (2/8)·25 ft²/s = 6.25 ft²/s
The am not sure but i belive the answer is 74.60
answer:
slope: -2/3
step-by-step explanation:
y=mx+b
m represents the slope, and b the y-intercept.
rearrange: 9x= -6y+18
---> -6y= -9x-18
divide all terms by -6.
-6y/-6= -9/-6x-18/-6
y= 3/2x+3 (slope/intercept form)
m= 3/2
---> 1/3/2= -2/3
Answer:
- domain: all real numbers
- range: all positive real numbers
Step-by-step explanation:
The function is defined for all values of x, so the domain is all real numbers.
An exponential function has a horizontal asymptote at y=0. Multiplying it by 4 doesn't change that. The value cannot be zero, and it cannot be negative. The range is all positive real numbers.
