Answer:

The small tire would make about 127 rotations.

The large tire would make about 38 rotations.

b. Would you rather ride a bicycle made with two large wheels or two small wheels? Explain.

Two large wheels. Because the larger wheel makes a smoother ride and you spend less energy in order to move, compared to smaller wheels. Also, the larger the diameter, the further it can travel over one revolution.

A bicycle with would allow you to travel farther with each rotation of the pedal.

The larger one. Because in one rotation the larger wheel moves 188.49 inches and the smaller one 56.55 inches.

$C= 188.49\text{inches}$

$C= 56.55\text{inches}$

Step-by-step explanation:

- Big wheel 60 inches

- Small wheel 18 inches.

a. How many rotations does each tire make after traveling 600 feet? Round your answers to the nearest whole number.

Considering: $C=\pi d$

Large tire:

$C=60\pi$

$C= 188.49\text{inches}$

$C=\frac{188.49}{12} = 15.7 \text{feet}$

$\frac{600 }{15.7} = 38 \text{rotations}$

Small tire:

$C=18\pi$

$C= 56.55\text{inches}$

$C=\frac{56.55}{12} = 4.71 \text{feet}$

$\frac{600 }{4.71} = 127 \text{rotations}$

The coordinates of the endpoints of the diameter of a circle are (-1,5) and (3, -1). The center of the circle has coordinates

Setler79 [48]

Answer:

ans=(-2,2)

Step-by-step explanation:

let the end point of circle diameter (-1,5) and (3,-1) be (x1,y1) and (x2,y2) respectively

using mid point formula

(x,y)=(-1,5)/2+(-3,-1)/2 [center point is equal to mid point of diameter)

= (-1+(-3))/2+(5-1)/2

=(-2,2)

center coordinate of circle=(-2,2)

What is the rule? And wat are the next two numbers of the pattern

Alex777 [14]

So, the next two numbers are 55 and 89

So,

1+1=2

1+2=3

2+3=5

Starting at the 1,1 add them together to get the next number which is 2. Then 1,2 add 1+2 to get the next number which is 3. Next, 2,3 add 2+3 to get the next number which is 5

I hope you understand that. I tried to explain it at the best of my ability

(3+4x)(3-4x) if necessary combine like terms

9-16x^2
This is the answer pretty much the 3 is okay but once you see the four notice there’s - and + you’d multiply it
