Answer: Last option: G<span>raph of y equals cube root of the whole of x plus 2</span>
Since lateral surface of an object is the area of all the sides of the object, except the area of its base and top.
It is:
7 * 3 = 21
21 * 2 = 42
12 * 3 = 36
36 * 2 = 42
42 + 42 = 84 in2
and there goes your answer.
A: 84 in2.
Answer:
In vertex form it's 
In standard form it's 
Step-by-step explanation:
We can use the vertex form to solve for a in
"a" is the number out front that dictates the steepness, or lack thereof, in a parabola. That means that we need h and k (which we have in the vertex) and we need x and y (which we have in the form of one of the zeros). Filling in using a vertex of (-7, -9) and a coordinate point (-7, 0):
simplifies a bit to
simplifies a bit more to
and
so
,
and finally,
a = 1
Phew! So there is the a value. Now we can simply fill in the formula completely, using the vertex as our guide:
In standard ofrm that is
We can check ourselves for accuracy by factoring that standard polynomial using whatever method of factoring you like for quadratics and get that the roots are in fact x = -10, -4
The only reason we needed the zeros is to use one of them as the x and y to solve for a.
The time taken for the person to get to school based on the equation will be 7 minutes.
<h3>How to calculate the time?</h3>
From the information given, the equation is given as:
g(x) = x⁴ - 3x² + 4x - 5
Then, we'll put 2 as x. This will be:
= 2⁴ + 3(2)² + 4(2) - 5
= 16 - 12 + 8 - 5
= 7
Therefore, the time taken for the person to get to school based on the equation will be 7 minutes.
