Answer:
Step-by-step explanation:
We want to write a quadratic function in vertex form whose vertex is (1, 0) and passes through the point (2, -17).
Recall that vertex form is given by:
Where (<em>h</em>, <em>k</em>) is the vertex and <em>a</em> is the leading coefficient.
Since our vertex is at (1, 0), <em>h</em> = 1 and <em>k</em> = 0:
It passes through the point (2, -17). Hence, when <em>x</em> = 2, <em>y</em> = -17:
Solve for <em>a: </em>

<em />
<em />
In conclusion, our quadratic function in vertex form is:
1. the mean is 16
2. the mean is 22.5
the formula that can be used to calculate the mean is
= sum of terms/number of terms
for the first question the mean can be calculated as follows
sum of terms= 20+15+19+16+10
= 80
number of terms= 5
mean= 80/5
= 16
for the second question the mean can be calculated as follows
sum of terms= 19+23+11+30+27+27+22+26+16+24
= 225
number of terms= 10
mean= 225/10
= 22.5
Hence the mean for the first expression is 16 and the mean for the second expression is 22.5

The Volume of the box is 78 inches.
How I got my answer:
The formula for Volume is length x width x height, so 6.5 x 6 x 2 equals 78.
