<span>The arc length in degrees (same as central angle that cuts it off) is to 360 (degrees in a circle) AS the arc length in linear measure is to the circumference of the circle (2 pi r).
90/360 = AL/[2 pi (85)] where AL is the arc length in linear measure.
1/4 = AL/[170 pi]
4 AL = 170 pi
AL = 42.5 pi
AL = 133.45 feet (approx)

The time it will take for the block of ice to melt if the temperature is 45 degrees is 3 hours.
The cost to travel 22 miles is 55 dollars.
<h3>How to find how long for the ice to melt?</h3>
let
time it takes for ice to melt = x
air temperature = y
Therefore,
x ∝ 1 / y
x = k / y
when x = 2.5 hours and y = 54 degrees
Hence,
k = 2.5 × 54
k = 135
The time it will take for the block to melt at 45 degrees = 135 / 45 = 3 hours
<h3>How to find equation that relates the cost to the number of miles?</h3>
It costs $35 for a ride from the city centre to the airport, 14 miles away.
where
c = cost
m = number of miles
Therefore, the equation is as follows:
35 / 14 = 2.5
c = 2.5m
Hence, when you travel 22 miles,
c = 22(2.5)
c = 55 dollars

6 units to the left and 7 units down will get you A'B'C'D
Answer:
Step-by-step explanation:
There are many such polynomials, but the one with leading coefficient of 1 is
y = (x+1)(x-1)(x-6) = x^3 - 6x^2 - x + 6
Not sure what you want to do with the 5, If that is the y-intercept, then since
(1)(-1)(-6) = 6, we will need
y = 5/6 (x^3 - 6x^2 - x + 6)
