Hello there, and thank you for posting your question here on brainly.

Short answer: C. Product of 2 rational numbers = a rational number.

Why?

The numbers are both rational because squared is a result of a number multiplied by itself. Like (3^2 = 9). It turns out as a rational number because you're multiplying by two positive numbers, which always turns out as a rational number. (3^2 * 4^2 ==> 144) [3^2 = 9] [4^2 = 16]

Hope this helped you! ♥

Graph the direct variation y=−1.5x. Using the graph, find:
Mariana [72]
Y=-3

-3=-1.5x
you substitiue y value, then you divide both sides by -1.5 and you get 2 for x.
(2,-3)

y=4.5
4.5=-1.5x
you substitute y value, then again you divide both sides by -1.5 and you get 3.
(3,4.5)



y=6
6=-1.5x
same thing for this last one. then once again divide by -1.5 and you get -4.
(-4,6)

2 different companies offer online subscriptions. Company A charges $75 upfront and $20 per month. Company B does not charge the
ki77a [65]

Answer:

15 months

Step-by-step explanation:

Given that company A charges  \$75 upfront and \$20 per month and company B does not charge the upfront fee but charges \$35 per month.

Let after n months both the company charges the same amount.

Total charges by the company A=\$ (75+n\times 20) and total charges by the company B=\$ (n\times 35).

Now, from the given condition both the charges are equal, so

75+n\times 20=n\times 35 \\\Rightarrow 75= 35 n - 20 n\\\Rightarrow 75= 15 n \\\Rightarrow n= \frac {75}{5} \\\Rightarrow n= 15

Hence, after 15 months both the company charges the same amount.

Cassandra assigns values to some of the measures of triangle ABC. If angle A measures 30°, a = 6, and b = 18, which is true?
Anna [14]

Answer:

The triangle does not exist because sin(A)/a can not be equal to sin(B)/b

Step-by-step explanation:

we know that

step 1

Find the measure of angle B

Applying the law of sines

\frac{sin(A)}{a}=\frac{sin(B)}{b}

we have

A=30\°

sin(30\°)=1/2

a=6\ units

b=18\ units

substitute

\frac{(1/2)}{6}=\frac{sin(B)}{18}

\frac{1}{12}=\frac{sin(B)}{18}

sin(B)=\frac{18}{12}

sin(B)=\frac{3}{2}=1.5

Remember that the value of sine can not be greater than 1

therefore

The triangle does not exist because sin(A)/a can not be equal to sin(B)/b
