Answer:
C. Ferris wheel
Step-by-step explanation:
Circumference = pi x diameter
Take each of the entries from the diameter column and multiply by 3.14. They are all correct except for the Ferris wheel.
70.5 x 3.14 = 221.37
Answer:
Option B. y = csc(x) + 1
Step-by-step explanation:
If we have to draw an asymptote graph( csc graph), we should draw the graph of sine first.
For y = a sin(bx+c) +d
Here from the given graph
a = (0+2)/2 = 1
period = (3π/2-π/2) = 2π
Therefore b = 2π/period = 2π/2π = 1
b = 1
Vertical shift d = 1
Now the equation will be y = 1×sin(1.x+0)+1
y = sinx + 1
Now we draw the sine graph y = sinx +1
Then we draw asymptotes touching the maximum and minimum values of sine graph.
Which reflects It's a graph of y = csc(x) + 1
Therefore option B. is the right answer.
Each strip is 29 cm
------------------------------------------------------
Change the m to cm
------------------------------------------------------
6 m = 600 cm
------------------------------------------------------
Find the number of strips for 1 6m-board
------------------------------------------------------
Find the number of strips that can be cut from the 6m board.
600 ÷ 29 = 20 pieces remainder 20cm
So we can only cut 20 pieces of 29 strips from one 6m board.
------------------------------------------------------
Find number of boards needed
------------------------------------------------------
70 ÷ 20 = 3.5
We need 3.5 of the 6m boards.
Since she can't have half a board, she has to buy 4 pieces of the board.
------------------------------------------------------
Answer: 4 pieces of the 6m board.

Answer:
1/12
Step-by-step explanation:
The slope of a line given 2 points is found by
m = (y2-y1)/(x2-x1)
=(2-3)/(-7-5)
=-1/-12
= 1/12
