He does not. 5.79 + 7.63 + 3.46 +2.99 + 3.65 is equivalent to $23.52. And on top of that you don’t know if it’s before or after tax.

Answer:Sample Response: Larry did not round correctly. He used front-end estimation, but he did not round up when appropriate. His estimate will be lower than the amount of money he needs.

Suppose that F(x) = x2 and G(X) = 2/3 x^2. Which statement best compares the graph of G(x) with the graph of F(x)?
masha68 [24]
<h2>Answer:The graph of G(x) is the graph of F(x) compressed vertically.</h2>

Step-by-step explanation:

Given that F(x)=x^{2} and G(x)=\frac{2}{3}x^{2}

F(x) is always positive because x^{2} is always positive.

G(x) is always positive because \frac{2}{3}x^{2} is always positive.

So,both are always positive.

So,there is no flipping over x-axis.

In F(x),the height of a point at x_{0} is x_{0}^{2}

In G(x),the height of a point at x_{0} is \frac{2}{3}x_{0}^{2}

So,height of any point has less height in G(x) than F(x)

So,the graph of G(x) is the graph of F(x) compressed vertically.

Find a formula for the given polynomial.
levacccp [35]

In this question, we have to identify the zeros of the polynomial, along with a point, and then we get that the formula for the polynomial is:

p(x) = -0.5(x^3 - x^2 + 6x)

------------------------

Equation of a polynomial, according to it's zeros:

Given a polynomial f(x), this polynomial has roots such that it can be written as: , in which a is the leading coefficient.

------------------------

Identifying the zeros:

Given the graph, the zeros are the points where the graph crosses the x-axis. In this question, they are:

x_1 = -2, x_2 = 0, x_3 = 3

Thus

p(x) = a(x - x_{1})(x - x_{2})(x-x_3)

p(x) = a(x - (-2))(x - 0)(x-3)

p(x) = ax(x+2)(x-3)

p(x) = ax(x^2 - x + 6)

p(x) = a(x^3 - x^2 + 6x)

------------------------

Leading coefficient:

Passes through point (2,-8), that is, when x = 2, y = -8, which is used to find a. So

p(x) = a(x^3 - x^2 + 6x)

-8 = a(2^3 - 2^2 + 6*2)

16a = -8

a = -\frac{8}{16} = -0.5

------------------------

Considering the zeros and the leading coefficient, the formula is:

p(x) = -0.5(x^3 - x^2 + 6x)
