Which is the BEST estimate of the average rate of change for the function graphed, over the interval 1 sxs 3?

Answer: -3

Step-by-step explanation: just multiply

The best estimate of the average rate of change for the function graphed over the interval 1 ≤ x ≤ 3 is 3.

What is Average Rate of Change of a Function?

Average rate of change of a function is defined as the rate at which the value of the function is changing with respect to the change in the input values.

The interval given is 1 ≤ x ≤ 3.

The graph of the function is given below.

It can be clearly seen that,

The y value corresponding to x = 1 is y = f(1) = 2.

So one point on the graph is (1, 2).

The y value corresponding to x = 3 is y = f(3) = 8.

So the other point on the graph is (3, 8).

Average rate of change over 1 ≤ x ≤ 3 = [f(3) - f(1)] / [3 - 1]

                                                               = [8 - 2] / [2]

                                                               = 6/2

                                                               = 3

Hence the best estimate for the average rate of change of function over the interval 1 ≤ x ≤ 3 is 3.

The graph below shows the relationship between the amount of peanuts and the amount of chocolate in different packages of snack mix for each ounce of peanuts? A.1/2 B.2/3 C.3/4 D.3/2 please i need answers !!!!

Answers

Answer:

Option (B)

Step-by-step explanation:

Since the linear graph is passing through the origin, there is a proportional relationship between the amount of chocolate (C) and amount of peanuts (P) used in the package of snacks mix,

P ∝ C

P = kC

k = [tex]\frac{P}{C}[/tex]

Here k = proportionality constant

Since, the given line passes through a point (3, 2),

k = [tex]\frac{2}{3}[/tex]

Therefore, ratio of chocolate and peanuts mixed is [tex]\frac{2}{3}[/tex].

Option (B) is the correct option.

Answer:

if ∠1 = 70°, then ∠5= 70°

Hence, option (A) is correct.

Step-by-step explanation:

Given

∠1 = 70°

To determine

We need to determine angle ∠5

From the diagram, it is clear that a transversal line crosses the two parallel lines, the angles in the matching corner would be corresponding angles.

We know that when two lines are parallel, their corresponding angles are equal.

As angle ∠5 is the corresponding angle of angle ∠1 = 70°.

Also, the corresponding angles are equal here.

Therefore,

if ∠1 = 70°, then ∠5= 70°

Hence, option (A) is correct.

You are eating a slice of pizza that has 391 calories in it. Each time you dip the pizza into ranch dressing, though, you add 7 calories to the total. If your meal wound up being 454 calories in total, how many times did you dip the pizza into ranch dressing? I don't get it

Answers

Answer:I think it is about 55 times

Step-by-step explanation:

Answer:

9 times

Step-by-step explanation:

The pizza has 391 calories in it, and everytime you dip it into ranch, you add 7 calories to the 391.

454(calories in total) - 391(calories in the pizza)= 63

63 ÷ 7(calories everytime you dip into ranch) = 9

Equality Properties

Geometry

Definition of a Line: A line is 180°

Step-by-step explanation:

Step 1: Set up Equation

m∠BDC + m∠CDA = 180°

(-7x + 12)° + (-8x + 48)° = 180°

Step 2: Solve for x

Combine like terms:                    -15x + 60 = 180Isolate x term:                              -15x = 120Isolate x:                                       x = -8

Step 3: Find m∠BDC

Define:                    m∠BDC = (-7x + 12)°Substitute in x:       m∠BDC = (-7(-8) + 12)°Multiply:                  m∠BDC = (56 + 12)°Add:                        m∠BDC = 68°

The length of a rectangle is 5 less than 3 times its width. The perimeter is
78. Find the LENGTH.*

Answers

Answer:

The length is 28 and the width is 11

Step-by-step explanation:

To solve this problem, we can make the width as x.

Since the length is 5 less than 3 times the width, it's going to be 3x - 5

So now we've got the length and width, just need to find the perimeter, which is all the sides added up together. They already gave us the perimeter, so we just have to solve the equation:

2(3x - 5) + 2x = 78

6x - 10 + 2x = 78

8x - 10 = 78

8x = 88

x = 11

x = 11, but remember, x is the width, not the length. Since we already found what x is, we just have to plug it into the equation of:

3x - 5

3 × 11 - 5

33 - 5 = 28

Answer: Length = 28 (don't forget to add the unit if there is one)
