Can y’all help me pls

Answer:

2. The change in expected height for every one additional centimeter of femur length.

Step-by-step explanation:

<u>1. The expected height for someone with a femur length of 65 centimeters.</u>

<em>Doesn't make sense, that would be height value when centimeters = 65.</em>

<u>2</u><u><em>. </em></u><u>The change in expected height for every one additional centimeter of femur length.</u>

<em>Makes sense, for every increase in one additional centimeter, we can expect the height to be proportional to the slope.</em>

<u>3. The femur length for someone with an expected height of 2.5 centimeters.</u>

<em>Doesn't make sense, the linear relationship relies on the femur length to get the height.</em>

<u>4. The change in expected femur length for every one additional centimeter of height.</u>

<em>Doesn't make sense, again, the linear relationship relies on the femur length.</em>

A computer hard drive contains a circular disk with diameter 2.5 inches and spins at a rate of 7200 RPM (revolutions per minute)
PIT_PIT [208]

Now to solve this problem, all we have to remember is the formula for calculating the linear speed given the radial speed, that is:

v = r w

where,

v = is the linear velocity or linear speed

r = is the radius of the circular disk = (1 / 2) diameter = (1/ 2) (2.5 inches) = 1.25 inches

w = is the radial velocity (must be in rad per time) = 7200 rev per minute

 

Calculating for v:

v = 1.25 inches (7200 rev per minute) (2 π rad / 1 rev)

v = 56,548.67 inches / minute

 

Converting to miles per hour:

v = 56,548.67 inches / minute (1 mile / 63360 inches) (60 min / hour)

<span>v = 53.55 mile / hour</span>

Find the the equation of the line passing through the points (3,3) and (4, 5)
Nostrana [21]

Answer:

y = 2x - 3

Step-by-step explanation:

Given:

(3, 3) and (4, 5)

Solve:

Find the slope (m) between the two points:

m = (y2 - y1)/(y2 - 1)

(x1, y1) = (3, 3)

(x2, y2) = (4, 5)

m = (5 - 3)/(4 - 3)

= 2/1

m = 2

Slope-intercept form (y = mx + a):

y = 2x + a

To find a, plug in one of the points into the equation:

3 = 2(3) + a

3 = 6 + a

3 - 6 = a

a = -3

y = 2x - 3
