Answer:

48

Step-by-step explanation:

First find the median:

16,26,48,56,61,85,88,88,88,91,91​

85 is the median.

Now, find the median of the first set of bold numbers.

<u>16</u>,<u>26</u>,48,<u>56</u>,<u>61</u>

The median of the first bold set of numbers will be lower quartile.

The lower quartile is 48.

use the slope formula to calculate the slope of the line that contains the two points (-4,0) and (5,2)​
Solnce55 [7]

Answer:

\frac{2}{9} x

Step-by-step explanation:

To find slope using two points you need to find the difference in x and y. You use \frac{y_{2}-y_{1}}{x_{2}-x_{1} }

So, 2-0=2 and 5-(-4)=9. Therefore the slope is 2/9x

What is the vertex of g(x) = –3x2 + 18x + 2?
blsea [12.9K]

Answer:

(3,29)

Step-by-step explanation:

There is a formula that can be used to find the x-value of the vertex of the parabola. This formula is x=\frac{-b}{2a}

We have the function g(x)=-3x^2+18x+2

From this function, we can find that

a=-3\\b=18\\c=2

We can plug in our know values into the formula to get

x=\frac{-18}{2(-3)\\} \\x=\frac{-18}{-6} \\\\x=3

Then we can plug in our x-value to find the y-value of the vertex

g(3)=-3(3)^2+18(3)+2\\\\g(3)=-3(9)+54+2\\\\g(3)=-27+54+2\\\\g(3)=29

This means that the vertex would be (3,29)
