Hello,
√52-√13+√117=√(4*13)-√13+√(9*13)
=√13*(2-1+3)=4√13
Answer A
x is the number od doubling periods ( which is given as every 7 years)
28 years / 7 = 4 doubling periods in 28 years
so x = 4
so you now have:
f(x) = 8000 * 2^4
2^4 = 16
so 8000 * 16 = $128,000 would be the answer

The formula for the volume of a cylinder is pi * radius squared * height, or πr^2h.
To find the radius of the cylinder, take the given diameter (60 cm) and divide it by 2. 60 / 2 = 30 cm.
Now we need to either find the height in centimeters or find the radius in meters. Because a centimeter is 1/100 of a meter, we multiply the radius by 100 to get the radius in meters.
We also must square the radius. So 30 cm multiplied by itself equals 900 cm.
Radius: 900 / 100 = 9 m
We have to square the radius before plugging it into the equation because it would mess up the numbers if we didn't (0.3 m squared is 0.09 m, which is very small).
Now we can plug these values into the formula for the volume of a cylinder.
π * r^2 * h = π * 9 m * 1.7 m = ~48.066 cubic meters
Rounded to two decimal places is 48.07 cubic meters.
The volume of the tree trunk is about 48.07 cubic meters.

I explained all of these in the last upload of this
Step-by-step explanation:
I'm just here to claim some of the points ;)
I'm glad you understand them now!
Well let's break this down:
<span>2 less than the product of 3 and x is squared means:
</span>
<span>the product of 3 and x is squared-2
the product of 3 and x is squared means
(3x) squared
or
(3x)^2
Now combine that with your first deduction to get </span>
<span>(3x)^2-2 or D</span>
