Answer:

D. -4

Step-by-step explanation:

Using the general formula, \( m = \frac{f(b) - f(a)}{b - a} \) , average rate of change for the quadratic function from x = 1 to x = 3, can be calculated as shown below:

Where,

\( a = 1, f(1) = -2 \)

\( b = 3, f(3) = -10 \)

Plug in the above values in the average rate of change formula:

\( m = \frac{-10 - (-2)}{3 - 1} \)

\( m = \frac{-10 + 2}{2} \)

\( m = \frac{-8}{2} \)

\( m = -4 \)

Average rate of change is D. -4

Answer:

3(16x+9)/4

Answer:

27 11/4x

Step-by-step explanation:

First we add the similar parts of the expression.

Whole numbers

6 + 9 + 5 + 7 = 27

Then we add the fractions that dont have x.

We only add the numerators (2 and 3) and dont change the denominators (4)

2/4 + 3/4 = 5/4

Now we add the ones with x.

5/4 + 3/4x + 3/4x = 11/4x

Now we combine those parts together, making

27 11/4x

Answer:

c. 384 square feet

Step-by-step explanation:

First, you must find the total area of the pool and deck combined. Because the deck is 4 feet wide and it wraps around the entire pool, 8 feet can be added to both the length and the width of the pool to get the measurements of the whole rectangle combined.

25+8=33

15+8=23

To get the total area you multiply 33 by 23

33 x 23= 759

Then you get the area of the pool alone by multiplying 15 by 25

15 x 25= 375

Then you subtract the area of the pool from the total area to get the area of the deck

759-375=384

Answer:

It's the first one.

Step-by-step explanation:

The first one cannot be folded into a square because of its shape. This question is more of an IQ question so it's not really something you can teach to someone else, but I hope this helps and that you will get it!

The number of purple T shirts that the Trenton's scouting group made is 15.

A pie chart is a type of graph where a circle is divided into certain sectors where each sector shows a proportion of the whole.

Given is a pie chart or circle graph.

This shows the number of different colored T shirts that the Trenton's scouting group made.

Total number of T shirts = 100

Total degree of a circle = 360°

The circle is divided in to various sections with each section of different degree.

Angle measure for the purple section = 54°

Proportion of purple T shirts to the full T shirts = 54 / 360

                                                                             = 0.15

Number of purple T shirts in total of 100 T shirts = 0.15 × 100

                                                                                = 15

Hence the number of purple T shirts made is 15.

Answer:

Step-by-step explanation:

No it cannot. There are a couple of ways to prove this. The easiest way is that we know by looking at the angles that we have an Isosceles triangle, because we have 2 angles of the same value. We know that an Isosceles triangle must have at least 2 sides of the same length, which means that this triangle cannot have the side lengths listed.

Answer:

1.

Step-by-step explanation:

By the order of operations, multiplication goes before addition. We got left to right.

As the entire resultant expression of the first two operators is multiplied by 0, we are left with 0 + 1.

0 + 1 = 1.

Step-by-step explanation:

50.2 = 5.02 × 10¹

1102 = 1.102 × 10³

so,

50.2 × 1102 = 5.02 × 1.102 × 10³×10¹ =

= 5.02 × 1.102 × 10⁴

Answer:

Step-by-step explanation:

Let’s mark the Triangle Points as Point A, Point B, Point C.

Point A = 1x°

Point B = 2x°

Point C = 3x°

We know that the Angle Sum of a Triangle is equal to 180°.

So, Point A + Point B +Point C = 180°

   = 1x° + 2x° + 3x° = 180°

   = (1 + 2 + 3)x° = 180°

   = 6x° = 180°

   = x° = (180/6)°

   = x° = 30°

Answer:

  C  7

  D  157°

Step-by-step explanation:

You want to know the value of x and the measure of angle A in the given figure.

The angles marked with x-expressions are vertical angles, so have the same measure.

  (x +16)° = (4x -5)° . . . . . the angle measures are the same

  21 = 3x . . . . . . . . . . . . divide by °, add 5-x to both sides

  7 = x . . . . . . . . . . . . divide by 3

The value of x is 7.

The angles marked with x-expressions each form a linear pair with the angle marked A. That means they total 180°.

  (x +16)° +A = 180°

  A = 180° -23° = 157° . . . . . . . use x=7 and subtract 23

The measure of angle A is 157°.

Answer:

A. $2.00

B. $26.99

Step-by-step explanation:

0.5 x 49.99 = 24.995

49.99 - 24.995 = 24.995

0.08 x 24.995 = 1.9996 and round to the nearest hundredth

24.995 + 1.9996 = 26.9946

round to the nearest hundredth

Answer:

Part a: 1.9996

Part b: 26.9946

Step-by-step explanation:

STEP 1:

Find the unit rate (1% of 49.99). You should get 0.4999. Then, multiply 0.4999 by 50. You should get 24.995.

STEP 2:

Find the unit rate of 24.995. You should get 0.24995. Then multiply 0.24995 by 8. You should get 1.9996 (answer for part a).

STEP 3:

Add 1.9996 to 24.995. You should get 26.9946 (answer to part b).

Subtract 92 from each side

2w+92-92 = 22-92

2w = -70

Divide each side by 2

2w/2 = -70/2

w = -35

Answer:

x = 20

Step-by-step explanation:

x, 7x, and x are all supplementary angles which means they all add up to 180:

x + 7x + x = 180

9x = 180

x = 20

Answer:

x° = 20°

Step-by-step explanation:

From the diagram, we see that 9x for a straight angle, therefore we know the following...

9x° = 180°

x° = 180° / 9

x° = 20°

Answer:

Airplane A has a lesser Interquartile range.

Step-by-step explanation:

To find the interquartile range, subtract the lower quartile from the upper quartile.

Airplane A = Upper quartile - lower quartile

Airplane A = 225 - 209 = 16

Airplane B = Upper quartile - lower quartile

Airplane B = 230 - 205 = 25

Therefore airplane a has a lesser interquartile range.

\(\bigg(3^6\bigg)^{\frac{1}{2}}\)

use

\((a^n)^m=a^{n\cdot m}\)

\(\bigg(3^6\bigg)^{\frac{1}{2}}=3^{6\cdot\frac{1}{2}\)

simplify

\(6\!\!\!\!\diagup^3\cdot\dfrac{1}{2\!\!\!\!\diagup_1}=3\cdot\dfrac{1}{1}=3\cdot1=3\)

other

\(6\cdot\dfrac{1}{2}=\dfrac{6\cdot1}{2}=\dfrac{6}{2}=3\)

therefore
