Answer:

Step-by-step explanation:

So we have the function:

$g(t)=t^2-2$

To find g(9), substitute 9 for t. Thus:

$g(9)=9^2-2$

Square:

$g(9)=81-2$

Subtract:

$g(9)=79$

So, our answer is 79.

And we're done!

Y=1/3x what is the slope

Karolina [17]

Answer:

Slope = $\frac{1}{3}$

Step-by-step explanation:

The equation for finding slope is:

$y = mx+b$

In the equation, m is the slope, x is the x-intercept, and b is the y-intercept. The number next to x is ALWAYS the slope.

Your equation:

$y = \frac{1}{3} x$

The number(fraction) next to x is $\frac{1}{3}$ . Therefore, your answer will be $\frac{1}{3}$

Solve for x. Worth 20 pts.

Vinvika [58]

You’d set up a proportion. I did 25/15=7x-40/18.
Then you would cross multiply to get 15(7x-40)=450
Distribute the 15.
105x-600=450
Add 600 to both sides, so the -600 cancels out.
Then you’re left with 105x=1050
Divide both sides by 105 and you get x=10

The drama club was selecting which carnival booths to sponsor at the fall carnival from a list of nine. How many different ways

denis-greek [22]

Answer:

Option B

Step-by-step explanation:

Here we have to apply " combination and permutation. " It is given that the drama club had to choose three booths from a selection of 9, considering the possible ways to choose so. This is a perfect example of combination. In nCr, n corresponds to 9, respectively r corresponds to 3.

$\mathrm{n\:choose\:r},\\nCr=\frac{n!}{r!\left(n-r\right)!},\\\\\frac{9!}{3!\left(9-3\right)!} =\\\frac{9!}{3!\cdot \:6!} =\\\\\frac{9\cdot \:8\cdot \:7}{3!} =\\\frac{504}{6} =\\\\84\\\\Solution = Option B$

Hope that helps!
