Answer:
The base is a 14 by 14 square
Step-by-step explanation:
Here is why, if you take 1,568 and divide by 8 you get 196. Square rooting that would give you 14. You need to square root since from the question the equation is clearly x^2*8 = 1568
Answer:
x=15
Step-by-step explanation:
So we know 4x plus 8x gets a total of 180 degrees (since a straight line is 180 degrees). Combine 4x and 8x to get 12x. To find x, divide 12 from 180. 180/12 is 15.
Answer:
(a)
(b)62.85cm
Step-by-step explanation:
The growth rate of the shrub is given as:

Where t=time in years, h=height in centimeters
(a)First, we solve for the height h(t) by integrating.

(b)The shrub are sold after 7 years of growth. Therefore, we determine the value of h(t) when t=7 years.

The Shrubs are 62.85cm tall when they are sold.
Answer:
3
Step-by-step explanation:
The average rate of change of f(x) in the closed interval [ a, b ] is

here [ a, b ] = [ 0, 2 ] and from the graph
f(b) = f(2) = 0
f(a) = f(0) = - 6, hence
average rate of change =
=
= 3
Answer:
$20,800
Step-by-step explanation:
There are 52 weeks in a year, therefore, do 100 x 52 = $5,200
You earn $5,200 a year, for 4 years so do 5,200 x 4 = $20,800
