I would really help if you turned the brightness up. So then I’ll be able to see the lines. I can hardly see where I crossed it. But for the 2nd blank it’s -6. And so for the first blank you’d do the rise over run. So however many times you rose and the amount of time you ran.

In the triangle below, what ratio is sin θ? right triangle with sides whose lengths are 5, 12, and 13; angle theta is opposite t

butalik [34]

If you sketch the triangle, you need to understand that 12 is the length of opposite side (opposite to theta). Then the longest side is 13 is the hypotenuse. The other side with length 5 is the adjacent side. Thus from the definition of sin(theta)=opposite side/hypotenuse=12/13. A question for you, what is cos(theta)? cos(theta)=5/15 and tan(theta)=12/5

Miss smith’s pay is directly proportional to the number of hours she work at the airport. Her pay for 22 hours is $297.How much

Troyanec [42]

Answer:

She should earn $540 in a 40 hour week

Step-by-step explanation:

we know that

Her pay for 22 hours is $297

using proportion

Find out how much should she earn in a 40 hours week

$\frac{22}{297}=\frac{40}{x}\\\\x=297*40/22\\\\x= \$540$

An electrician bent a section of copper wire into a partial circle as shown. The dimensions are

ira [324]

Answer:

Length = 3.84 feets (nearest hundredth)

Step-by-step explanation:

The length of section of wire can be obtyaiejd using the length of of a arc formular :

Length of arc = θ/360° * 2πr

Radius, r = 2.5 feets

Length of arc = (88/360) *2πr

Length of arc = (88/360) * 2π*2.5

Length of arc = 0.244444 * 15.707963

Length of arc = 3.8397

Length = 3.84 feets (nearest hundredth)

Which function represents a proportional relationship? A) f(x) = 3x 4 B) f(x) = 3 4x C) f(x) = 3x 4 + 3 4 D) f(x) = 3 4x + 3 4

densk [106]

Answer: OPTION B

Step-by-step explanation:

The equation of a line that passes through the origin is the following:

$y=mx$

Where "m" is the slope of the line.

By definition, Proportional relationships have the following form:

$y=kx$

Where "k" is the Constant of proportionality.

Then, as you can notice, if you graph a Proportional relationship you will get a line that passes through the origin.

Therefore, based on the explained above, you can conclude that the option that shows a function that represents a Proportional relationship is the Option B.

Then, this is:

$f(x)=\frac{3}{4}x$
