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:

$C=18\pi$

$C= 56.55\text{inches}$

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

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

What does |x| mean in a function?

seropon [69]

Answer:

<h2><u><em>The function basically returns the same objects (= does nothing). This could also be written explicitly as a named function. new Function <- function(x) { x } which would then be. cross val <- function(data, lambda=0, y trans = new Function) This is the default value, like in lambda=0, except the default value is a function itself.</em></u></h2><h2><u>brainlist plz </u></h2>

if an external point of a circle is at a distance equal to the diameter of the circle from the center of the circle, the length

jeka57 [31]

Let the radius of the circle be r. Then the line from the external point through the center of the circle which extends to the far point on the circle has length 3r .By the tangent - secant theorem

t^2 = 3r * r = 3r^2 ( where t is the length of the tangent).

So t = √(3r^2) = √3r answer.
