Answer:

d=10568.76rads

Step-by-step explanation:

From the question we are told that:

Angular Velocity \omega=580rpm=>60.74rads/sec

Time t=2.9mins=>174sec

Generally the equation for distance d is mathematically given by

 d=\omega*t

 d=60.74*174

 d=10568.76rads

wolverine [178]

Answer:

165 ft^2

Step-by-step explanation:

We need to break the figure into 2 parts

We have the square at the bottom right

The square is 5 by 5

A = 5*5 = 25

The rectangle is then 20 by (12-5) =7

The area of the rectangle is

A = 20 *7 = 140

Add the areas together

140+ 25

165 ft^2

Identify the level of measurement of the​ data, and explain what is wrong with the given calculation. In a​ survey, the favorite
Trava [24]

Answer:

The data are at the   <u>Nominal</u>   level of measurement.

The given calculation is wrong because average (mean) cannot be calculated for nominal level of measurement.

Step-by-step explanation:

The objective here is to Identify the level of measurement of the​ data, and explain what is wrong with the given calculation.

a)

The data are at the <u> Nominal  </u>  level of measurement due to the fact that it portrays the qualitative levels of naming and representing different hierarchies  from 100 basketball, 200 basketball, 300 football, 400 anything else

b) We are being informed that, the average​ (mean) is calculated for 597 respondents and the result is 256.1.

The given calculation is wrong because average (mean) cannot be calculated for nominal level of measurement. At nominal level this type of data set do not measure at all , it is not significant to compute their average​ (mean).

The length of overline CD is 12 units. C^ prime D^ prime is the image of overline CD under a dilation with a scale factor of n.
Rufina [12.5K]

Answer:

A, D , and E

Step-by-step explanation:

We have that:

\overline{CD} = 12 \: units

\overline{C'D'}

is the image of CD after a dilation of scale factor n.

We use the relation between the image length and object length:

\overline{C'D'} = n \times \overline{CD}

Option A

If n=3/2, then

\overline{C'D'}  =  \frac{3}{2}  \times 12 = 3 \times 6 = 18 \: units

This is true.

Option B

If n=4, then

\overline{C'D'} = 4 \times 12 = 36 \: units

This is false.

Option C

If n=8, then

\overline{C'D'} = 8 \times 12 = 96 \: units

This too is false.

Option D

If n=2, then

\overline{C'D'} = 2 \times 12 = 24 \: units

This is true

Option E

If n=3/4, then

\overline{C'D'} =  \frac{3}{4}  \times  12

\overline{C'D'} =  3 \times 3 = 9 \: units

This is also true.

Solve the system of equations. <br><br> 10x+y=−20 <br><br> y=2x2−4x−16<br><br> ( , ) and ( , )
Sladkaya [172]
I will go about solving this using the elimination method.

First, convert the equations.

10x + y = -20
4x + y = -12

Second, find the easiest variable to get rid of and get rid of it!  (In this case, y)  We will subtract to get rid of y.

6x = -8

Third, you want to solve the equation.

6x = -8 (divide by 6)
x = -1 \frac{1}{3}

Fourth, solve for y by inserting the answer for x into one of the equations.

10(-1 \frac{1}{3}) + y = -20
-13 \frac{1}{3} + y = -20 (subtract -13 \frac{1}{3})
y = -6 \frac{2}{3}

The solution for this system of equations is (-1 \frac{1}{3}, -6 \frac{2}{3}).
