Rafael races his bicycle for

pychu [463]

Distance traveled = 70 m
Number of rotations = 29

We know, Circumference * Number of rotations = Distance traveled
So, C = 70 / 29
C = 2.41 m

Now, we know, diameter = C / π
So, d = 2.41/3.14 = 0.768

In short, Your Answer would be: 0.8 m

Hope this helps!

Can someone please help me ASAP

Answer:

(4,12)

(-1,-3)

Step-by-step explanation:

x^2 - y = 4

y = 3x

Use substitution. Substitute 3x for y in the first equation

x^2 - (3x) = 4

x^2 -3x =4

Subtract 4 from each side

x^2 -3x -4 = 4-4

x^2 -3x-4 =0

Factor

(x-4) (x+1) =0

Using the zero product property

x-4 =0 x+1 =0

x=4 x=-1

Now to find y for each x solution

x=4

y =3x = 3(4) =12

(4,12)

x=-1

y =3x = 3(-1) =-3

(-1,-3)

Is shipping box is a shape of a cube. Each side measures 3c^6d^2 inches. Express the volume of a cube has a monomial.

liubo4ka [24]

Length of each side of cube is = $3c^6d^2$

SO the volume of cube = $(Side)^3$
= $(3c^6d^2)^3$
= $27 * (c^6)^3(d^2)^3$
= $27c^{18}d^6$

SO the volume of cube is $27c^{18}d^6$

Answer:

8 units

Step-by-step explanation:

Displacement is the area under the velocity curve. The area of interest is in the shape of a trapezoid, so we can use the formula ...

A = (1/2)(b1 +b2)h

to find the area.
