We know that
[length of a circumference]=2*pi*r
diameter=90 cm-------------> r=d/2--------> r=45 cm
[length of a circumference]=2*pi*45----------> 90*pi cm

<span>with 1 revolution will go the length of the wheel</span>

if 1 revolution is-------------------> 90*pi cm
 5 revolution is--------------------> X
X=5*90*pi----------> 1413 cm

the answer is 1413 cm

Answer:

C

Step-by-step explanation:

f(x) = |x|: f(0) = 0, f(1) = 1, f(-1) = 1

f(x) + 5 = |x| --> f(x) = |x| - 5: f(0) = -5, f(1) = -4 f(-1) = -4

Therefore it shifts down by 5

Which digit is in the thousandths place?<br><br> 1,356.209
myrzilka [38]

Answer: 9

Step-by-step explanation: The thousandths place is always three spots away from the right side of the decimal place. Whenever the question asks for the thousandTHs place then it is a decimal the question is looking for. If it ask for the thousands place (with no th) then the question is looking for an actual number, not a decimal. Hope this helped!

I’m lost and unsure what is the first step to do find width of da roof
Monica [59]

Answer:

You set up an equation, using the trig function "tan" to find half of the roof (the equation would be tan(24) = 3.5/x, where x = 1/2 roof width)

Step-by-step explanation:

That would be the first step.

You solve the equation for x, and then multiply x by 2 to get the width of the roof.

Given the points A(-3, -2) and B(6, 1), determine the coordinates of point P on directed line segment that partitions in the rat
serg [7]

Answer:

P = (3,0)

Step-by-step explanation:

Given

A = (-3,-2) ---- (x_1,y_1)

B = (6,1) --- (x_2,y_2)

m:n =2:1

Required

The coordinates of P

This is calculated as:

P = (\frac{mx_2+nx_1}{m+n},\frac{my_2+ny_1}{m+n}]

So:

P = (\frac{2*6+1*-3}{2+1},\frac{2*1+1*-2}{2+1})

P = (\frac{9}{3},\frac{0}{3})

P = (3,0)
