Answer:
31869.5
Step-by-step explanation:
Circumcerence = distance travelled in one full rotation = 2 x π x 8 = 16π
for 2 minutes and 15 seconds,
multiply 16π by 2.25 as 2 minutes is twice the distance of one rotation and 15 seconds is a quarter more
therefore answer is 36π = 113.1 inches
ANSWER = 17.5% of 360 = 63
EXPLANATION:
Find 10% of 360 = 36
Then 5% of 360 = 18
Then 2.5% of 360 = 9
Add them together
so 17.5% of 360 = 63
The rate of change is the same as the slope.
Let's find the slope of function 1 using the Rise Over Run rule.
The rise is 2 and run is 1. So your rate of change is 2/1 or 2 for function 1
Function 2 is a y = mx + b equation, the slope is usually "m" or before the x
y = 1/2x + 7
1/2 is your rate of change for function 2
<span>cos (X) + sin (X) = 0
Subtract cos(x) from each side:
sin(x) = -cos(x)
Divide each side by cos(x) :
sin(x) / cos(x) = -1
But sin/cos = tangent
<em>tan(x) = -1</em>
x = 135° and 315°
x = 3/4 pi radians and 7/4 pi radians
