Answer: yes is at function

Step-by-step explanation:

because the x is not repeat -1,-1,-3,-4,-5

<h3>Answer: Yes it is a function</h3>

None of the x values repeat, so each x input leads to exactly one y output.

If you had two points such as (-1,1) and (-1,2), then the input x = -1 leading to multiple outputs y = 1 and y = 2 would rule it out of being a function.

Visually, plotting each point given shows that it is impossible to draw a single vertical line through more than one point, which shows the relation passes the vertical line test.

A point on the rim of a wheel has a linear speed of 33 cm/s. If the radius of the wheel is 50 cm, what is the angular speed of t

Zigmanuir [339]

Answer:

The angular speed of the wheel in radians per second is 0.66.

Step-by-step explanation:

Recall the following statement:

A linear speed (v) is given by,

$v=\omega \times r$ ...... (1)

Here, $\omega$ represents the angular speed of the wheel and <em>r</em> represents the radius of the wheel.

From the given information:

Linear speed (v) = 33 cm/s

Radius of the wheel (r) = 50 cm

Now to find the angular speed in radian per second.

$33 =50 \times \omega$

Divide both sides by 50.

$0.66 rad/sec= \omega$

Hence, the angular speed of the wheel in radians per second is 0.66.

Suppose Department X is 8,000 square feet, Department Y is 5,000 square feet, and Department Z is 6,000 square feet. What's the

den301095 [7]

Answer:

31.6%

Step-by-step explanation:

it is given that

Area of Department X = 8,000 square feet

Area of Department Y = 5,000 square feet

Area of Department Z = 6,000 square feet

now the total area = $8000+5000+6000$

= $19,000$ square feet

Percentage of area covered by Department Z = $\frac{area of Department Z}{total area }100$ %

= $\frac{6000}{19000} 100$ %

= $31.6$ %

percentage of overhead expenses applied to Department Z = percentage of area covered by Department Z

hence we have,

percentage of overhead expenses applied to Department Z = 31.6%

A class of 260 students went on a field trip. They took 12 vehicles, some cars and some buses. Find the number of cars and the n

Afina-wow [57]

The equation is 5c+25b=260 when c+b=12. rearrange that into 12-b=c. substitute and you get 5(12-b)+25b=260. b=10. 12-10=2, so 10 buses and 2 cars were used as transportation for the field trip.
