A polygon is shown. What is the area of the polygon ?

Answer:

C

Step-by-step explanation:

C. x=7, y=5

n = 66

Step-by-step explanation:

you can make a proportion 3/99 = 2/x

[tex] \frac{3}{99} = \frac{2}{x} [/tex]

99 * 2= 198

3 * x = 3x

so the equation would be 198 = 3x

than do 198 ÷ 3 on ur calculator

so x (or n in this context) would equal 66

Circle the first line.

His mistake was: He substituted y from 2nd equation in 1st equation incorrectly. There is a minus sign before y and it wasn't taken into the account.

The correct steps are:

2x - y = 18

2x - (4x + 2) = 18

2x - 4x - 2 = 18

-2x - 2 = 18

-2x = 20

x = -10

y = 4x + 2

y = 4(-10) + 2

y = -40 + 2

y = -38

Answer:

The choice C.

[tex] {x}^{ \frac{5}{2} } [/tex]

Step-by-step explanation:

[tex] \frac{ {x}^{3} }{ \sqrt{x} } = \frac{ {x}^{3} }{ {x}^{ \frac{1}{2} } } = {x}^{3} \times {x}^{ - \frac{1}{2} } \\ = {x}^{3 \times - \frac{1}{2} } = {x}^{ \frac{5}{2} } [/tex]

Or ;

[tex] \frac{ {x}^{3} }{ \sqrt{x} } = {x}^{2} \sqrt{x} = {x}^{2} \times {x}^{ \frac{1}{2} } \\ = {x}^{2 + \frac{1}{2} } = {x}^{ \frac{5}{2} } [/tex]

Answer:

The answer is C, y= -3/4 + 4

The correct answer to where the point(1, StartRoot 7 EndRoot) lies on the circle is A. Yes, the distance from (–2, 0) to (1, StartRoot 7 EndRoot) is 4 units

This refers to the tool that is used to graph points on a two-dimensional plane that intersects two number lines.

Hence, given the information in the given diagram, there is a coordinate plane that shows a circle at the center that has certain values on the y and x-axis.

We can state that the point (1, StartRoot 7 EndRoot) lies on the circle shown because the distance from (–2, 0) to (1, StartRoot 7 EndRoot) is 4 units.

The measure of the angle m1 is 110 degrees

The measures of the arcs are given as:

Arc 1 = 130

Arc 2 = 90

The measure of the angle is calculated using:

Angle = 0.5 * (Arc 1 + Arc 2)

So, we have:

Angle = 0.5 * (130 + 90)

Evaluate

Angle = 110

Hence, the measure of angle m1 is 110 degrees

The vertex of the parabola is (5, -4).

Hope this helps!

Answer:

(4,5)

Step-by-step explanation:

Hello!

If you move 5 units to the left, you change the x-value in (x, y) by -5.

Let the original x-value be x:

The original x-value is 4. Since you didn't change the y-value (up/down), you can keep the same y-value for the coordinate.

The original point was at (4,5)

Answer:

You started at (4, 5)

Step-by-step explanation:

The first number of coordinate pair is x. you started at the right and THEN moved the the left, as stated in the question. So -1 + 5 is 4.
So you started at (4, 5)

The solution to inequality is less than the negative of 21. Then the correct option is C.

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

The inequality is given below.

−(1/3)x + 10 > 17

Then the solution to the inequality will be

−(1/3)x + 10 > 17

       −(1/3)x > 17− 10

        −(1/3)x > 7

When the sign is changed then the equality sign also changed.

(1/3)x < −7

     x < − 21

The value of x is less than the negative of 21.

Thus, the correct option is C.

Answer: The awnser is linear.

I hope this helped.

Step-by-step explanation:

Answer:

the first option

Step-by-step explanation:

i know there's a rule to all of this but it's been a while since i've done this kind of math.

if you plug in the zeros to the equation, they solve

(-2, 0) --> (-2-2)(-2+1)(-2+2) = 0

(-1, 0) --> (-1-2)(-1+1)(-1+2) = 0

(2, 0) --> (2-2)(2+1)(2+2) = 0

The conclusion is that since the value of 0.028 is less than 0.05 so we reject the null hypothesis at 5% level of significance and conclude that the mean of the difference in SAT writing scores for all students who take SAT prep class is equal to 0.

A null hypothesis is a hypothesis that there is no significant difference between specified populations, any observed difference being due to sampling error.

Here, the effect of a one-day SAT prep class at a 5% level of significance was assessed.  Since the value of 0.028 is less than 0.05 so we reject the null hypothesis at 5% level of significance and conclude that the mean of the difference in SAT writing scores for all students who take SAT prep class is equal to 0.

The rate of change of the function the height of a plant is gotten as; D: 0.7

To find the rate of change, we will use the formula;

Rate of change = (y2 - y1)/(x2 - x1)

From the given table, we can solve for the rate of change by picking two consecutive points to get;

Rate of change = (9.6 - 8.2)/(2 - 0)

Rate of change = 1.4/2
