Answer:

Step-by-step explanation:

When comparing to standard form of a parabola: 
Vertex form of a parabola is:
, which is what we are trying to convert this quadratic equation into.
To do so, we can start by finding "h" in the original vertex form of a parabola. This can be found by using:
.
Substitute in -8 for b and 2 for a.

Simplify this fraction.


The "h" value is 2. Now we can find the "k" value by substituting in 2 for x into the given quadratic equation.

Simplify.


We have the values of h and k for the original vertex form, so now we can plug these into the original vertex form. We already know a from the beginning (it is 2).

Answer:
<em>Project 4 Score ; 41</em>
Step-by-step explanation:
Assuming that Project 4's score is x;
( Project 1 + Project 2 + Project 3 + Project 4 ) / 4 ⇒ take to substituting the value of each Project, provided Project 4's score being x;
45 = 42 + 49 + 48 + x / 4 ⇒ combine like terms,
45 = ( 139 + x ) / 4 ⇒ let 4 be a common denominator among numerator terms,
45 = 139 / 4 + x / 4 ⇒ divide 139 over 4,
45 = 34.75 + x / 4 ⇒ subtract 34.75 from either side,
10.25 = x / 4 ⇒ Multiply either side by 4,
x = 41 = Score of Project 4,
<em>Solution; Project 4 ⇒ 41</em>
Answer: C (3^6 x 5^6)
Step-by-step explanation: if you multiply 3 x 5 in the original question then you get 15^6. same with answer C
4 can be added to 5, and 3 can be added to 3. This should then give you a ratio of 9:6, which reduces to 3:2!
