I forgot the name, but there is a theorem that states that those two angles are equal. So if you do 94=5x+4 , you can solve that.

94=5x+4.
Subtract 4 from both sides
90=5x
Divide both sides by 5
18=x

Hope this helps :)

Finding the average rate of change of g(z) =4x^2_5 between the points( -2,11) and (2,11

krok68 [10]

Answer:

The average rate of change of g(z) =4x^2_5 between the points( -2,11) and (2,11) is 0.

Step-by-step explanation:

Given a function y, the average rate of change S of $y=g(z)$ in an interval $(z_{s}, z_{f})$ will be given by the following equation:

$S = \frac{g(z_{f}) - g(z_{s})}{z_{f} - z_{s}}$

In this problem, we have that:

$g(z) = 4z^{2} - 5$

Between the points( -2,11) and (2,11).

So $z_{f} = 2, z_{s} = -2$

$g(z_{f}) = g(2) = 4*(2)^{2} - 5 = 11$

$g(z_{s}) = g(-2) = 4*(-2)^{2} - 5 = 11$

$S = \frac{g(z_{f}) - g(z_{s})}{z_{f} - z_{s}} = \frac{11 - 11}{2 - (-2)} = \frac{0}{4} = 0$

The average rate of change of g(z) =4x^2_5 between the points( -2,11) and (2,11) is 0.

The pie chart shows information about voters in a election.2800 more women vote than men.

Lyrx [107]

ANSWER

The total number of voters is
$10080$

EXPLANATION

Let the
$x$
be the number of voters that are men.

Then the women will be
$x + 2800$

The total voters will be
$x + (x + 2800)$

$2x + 2800$

We now use ratio.

We can see from the diagram that,
$130 \degree$
corresponds to men.

We can write the ratio

$x:130 \degree$

Also the total number of voters corresponds to the angle in a complete circle. This will also give us the ratio,

$(2x + 2800):360 \degree$

We can therefore write the equation,

$\frac{2x + 2800}{x} = \frac{360 \degree}{130 \degree}$

$\frac{2x + 2800}{x} = \frac{36 }{13}$

We cross multiply to get,

$13(2x + 2800) = 36x$

This implies that,

$26x + 36400 = 36x$

We group like terms to obtain,

$26x - 36x = - 36400$

This implies that,

$- 10x = - 36400$

$x = 3640$

The total number of voters
$= 2(3640) + 2800$
$= 10080$

The total number of voters is
$10080$
