Answer:
130
Step-by-step explanation:
Given the equation of the relation as c(h) =50 +20 h where c(h) is the total cost for h hours and h is the number of hours of use, then to find the cost of jet ski if 4 hours were used will be;
c(h)=50 +20 h
c(4)=50 +20*4
c(4)=50 +80
=130
Answer:
a. f(n+1) = f(n) + 20
Step-by-step explanation:
The second hour, f(2) = 130 is the wage of the first hour f(1) = 110, plus 20.
_____
You have to look at the answers and understand what they mean. (This can be difficult when they are nonsense, as here.)
b — means each successive hour of pay is 110 more than the previous one. Clearly that is not the case for the sequence given
c — equates 0 to 20, total nonsense
d — equates 0 to 110, also total nonsense
Answer:
your answer is 200 if you add 84 and 116 but is you add 25 82 213 and 97 it will be 417

Answer:
The length around the figure in terms of r is 2r (
+ 4).
Step-by-step explanation:
The perimeter of an object is the total length of the boundary of the object.
The figure consists two similar semicircle and a rectangle.
Adding the two semicircles, a complete circle is formed. The circumference of a circle = 2r.
The rectangle has a length which is twice its height.
i.e l = 2h
But,
r = 
(the diameters of the semicircles equal the height of the rectangle)
⇒ h = 2r
Thus, one side length of rectangle = 2 × 2r (l = 2 × h)
= 4r
The length around the figure in terms of r is:
= 2r + 4r + 4r
= 2r + 8r
= 2r ( + 4)
The length around the figure in terms of r is 2r ( + 4).
