Which relation is a direct variation that contains the ordered pair (2, 7)?

Mathematics
1 answer:
Tasya [4]3 years ago
8 0
Lets write equation of a function:

y = kx + n

Direct variation in simple is equation of a line which has n=0 or in other words which y to x ratio is k.

First option gets 7=7 but it isnt direct variation because n is not equal to 0

third option is indeed correct. once we implement coordinates (2,7) we get 7=7

Answer is 
y = 7/2x

What is the slope of (-18,-20),(-18, -15)
Rzqust [24]

Answer:

Undefined.

Step-by-step explanation:

m =  \frac{rise}{run}

m =  \frac{ - 15 - ( - 20)}{ - 18 - (  -  18)}  \\ m =  \frac{ - 15 + 20}{ - 18 + 18}  \\ m =  \frac{5}{0}

The denominator is 0. Therefore, the slope is undefined.

A central angle of a circle measures 1.5 radians. If the radius of the circle is 3 cm, what is the area of the related sector?
soldi70 [24.7K]

Answer:

Option B. 6.75\ cm^{2}

Step-by-step explanation:

we know that

The area of a circle is equal to

A=\pi r^{2}

we have

r=3\ cm

substitute

A=\pi (3^{2})=9 \pi\ cm^{2}

Remember that

2\pi radians subtends the complete circle of area 9 \pi\ cm^{2}

so

by proportion

Find the area of the related sector for a central angle of 1.5 radians

Let

x------> the area of the related sector

\frac{9 \pi}{2\pi}\frac{cm^{2}}{radians} =\frac{x}{1.5}\frac{cm^{2}}{radians}\\ \\x=9*1.5/2\\ \\x= 6.75\ cm^{2}
