Answer:
The percent increase per year is 4%
Step-by-step explanation:
we have
This is a exponential function of the form
where
y represent the monthly rent at Lake View Apartments
x represent the number of years
a is the initial value (y-intercept)
b is the base
r is the rate or percent increase
The percent increase per year is the base of the exponential function decreased by 1.
so
In this problem we have
---> initial value
Therefore
The percent increase per year is 4%
Answer:
16. D. 180 inches
17. A. 1/20 pound
18. D. (2,6)
19. A. 2/8
20. D. 22
Step-by-step explanation:
16. every 5 feet is 60 inches there is 15 feet because 1 yard=3 feet so 60*3=180
17. when you round it upwards you would have 30/40 and 32/40 so it would be 2/40 and then simply 1/20 so therefore it would be 1/20
18. The cost of milk is 3 so that would be (3,y) then every gallon would be y so (3,1)
19. You know this because when you plug in all the other numbers none of the rest of them work but A so therefore it must be A
20. So first you would multiply 2*2*2*2=8 Then you would divide 172/8=22. So therefore your answer would be 22
Answer:
179.3 square units
Step-by-step explanation:
The area of the figure is the sum of the areas of the parts. That is, the area is the sum of the area of the rectangle, and the area of the semicircle.
__
<h3>Semicircle</h3>
The area of a circle with radius 5 is ...
A = πr²
A = π(5²) = 25π
The area of the semicircle is half that:
semicircle area = (25π)/2 = 12.5π ≈ 39.3 . . . . square units
<h3>Rectangle</h3>
The area of a rectangle with length L and width W is ...
A = LW
The width of this rectangle is the diameter of the circle, twice the radius, or 10 units.
A = (14)(10) = 140 . . . . square units
<h3>Total area</h3>
The sum of the areas of the parts is ...
total area = semicircle area + rectangle area
total area = 39.3 + 140 = 179.3 . . . . square units
