(a) The perimeter of the shape is the sum of half a circumference and the diameter itself.
The circumference of a circle with radius is , and since we can write the circumference as
So, half a circumference is
Ad we get the perimeter by addind the diameter:
(b) Given the perimeter, we can solve for :
So, we can divide both sides by the parenthesis and we have
Answer:x = the number of $1 increases in price
Price = ($60 + $1x) = (60+x)
Pairs of shoes (200 - 2x)
You have a quadratic Revenue = (60+x)(200-2x)
The quad max is when x = 20
Therefore they should charge 60+ 20 = $80

Answer:
Step-by-step explanation:
Figure 1
- 3 = 4 - 1 = 2² - 1 = (1 + 1)² - 1
Figure 2
- 8 = 9 - 1 = 3² - 1 = (2 + 1)² - 1
Figure 3
- 15 = 16 - 1 = 4² - 1 = (3 + 1)² - 1
<u>The function is:</u>
Answer:
The distance from his starting point is <u>6.7 m</u>.
Step-by-step explanation:
Given:
Shane marched 3 m East and 6 m north.
Now, to get the distance from his starting point.
Let the distance from the starting point be
Now, to solve using pythagorean theorem:
<em>Using square root on both sides we get:</em>
<u>So, the distance from the starting point nearest to tenth is 6.7 m.</u>
Therefore, he is 6.7 m from his starting point.
