Answer:
z^ {8/5}
Step-by-step explanation:

Answer:
A, 0.13 mph.
Step-by-step explanation:
To get that, divide the cm/sec by 44.704.
6/44.704 ≈ 0.13
The diameter of the sphere is 60 mm which means its radius is 30mm. <span>The radius of a sphere is increasing at a rate of 5 mm/s.
The formula for the radius when the time is x second would be:
</span>r(t)<span>= 30+ 5x
dr/dt= 5
The speed of </span><span>volume increase </span><span>of the sphere volume would be derived from sphere volume:
</span>V(r)=4/3* pi * r^3<span>
dV/dt= 4/3 * pi * 3r^2 * (dr/dt) =4/3* pi * 3(30)^2 * 5 = 18000 pi= 56571 mm^3/s</span>
"Product" means we are looking at a multiplication problem.
Can be written as:
A number (n) times 50
n x 50
The simplest (and most common way) to write it:
50n
The simplified answer is
.
<u>Step-by-step explanation:</u>

To add or subtract denominators of the fraction must be same.
If it is not the same, we must take LCM of the denominators. and so we can add the fractions.
To make the denominator same multiply the 1st term
and 2nd term by 
= 
LCM of the denominators is 6x²+ 3xz + 2xy +yz.
Multiply the factors in the numerator.
= 
Now, the denominators are same, you can subtract it.
= 
= 
Thus the simplified solution is
