What is the average rate of change from x = 0 to x = 2?

-4
-8
1
5

Answers

Answer:

The average rate will be: -4

Hence, option A is correct.

Step-by-step explanation:

Given the interval

0 ≤ x  ≤ 2

From the graph, it is clear that:

at x₁ = 0, f(x₁) = 3

at x₂ = 2,  f(x₂) = -5

Using the formula to determine the average rate of change:

Average rate = [f(x₂) - f(x₁)] / [ x₂ - x₁]

                      = [-5 - 3] / [2-0]

                      = -8 / 2

                     = - 4

Therefore, the average rate will be: -4

Hence, option A is correct.

K/3+4-5k=-2k what is the answer???

Answers

Answer:

Solve for k by simplifying both sides of the equation, then isolating the variable.

Exact Form: k = 3/2

Decimal Form: k = 1.5

Mixed Number Form: k = 1  1/2

Hope this helps!

Answer:

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

Step-by-step explanation:

Given

[tex]\frac{k}{3}[/tex] + 4 - 5k = - 2k

Multiply through by 3 to clear the fraction

k + 12 - 15k = - 6k

- 14k + 12 = - 6k ( add 14k to both sides )

12 = 8k ( divide both sides by 8 )

k = [tex]\frac{12}{8}[/tex] = [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

Alright for this type of problem the line CE is proportional to line FG meaning that the length of line CE is two times the length of EG. What we want to do is set up an equation that will help us solve for x. The equation would be

18-4x=6x-7 but because line CE is two time greater than line FG we have to multiply the side of EG by 2 so the new equation is

18-4x=12x-14 Now we can began to solve

step 1 : subtract 18 to each side

-4x=12x-32

step 2; subtract 12 from each side

-16x=-32

step 3: divide each side by -16

x=2

The faces of an eight-sided solid are labeled 1 through 8. Each

number has an equal chance of being rolled. Two of these solids

are rolled. What is the probability that an odd number is rolled on

both solids?

Answers

Answer:

The probability that an odd number is rolled on  both solids is [tex]\frac{1}{4}[/tex].

Step-by-step explanation:

Consider the provided information.

For the 8 sided dice the total number of outcomes = 64.

The favourable outcomes i.e odd numbers on both the solid = 16

(1,1), (1,2), (1,3), (1,4), (1,5), (1,6), (1,7), (1,8)  

(2,1), (2,2), (2,3), (2,4), (2,5), (2,6), (2,7), (2,8)

(3,1), (3,2), (3,3), (3,4), (3,5), (3,6), (3,7), (3,8)

(4,1), (4,2), (4,3), (4,4), (4,5), (4,6), (4,7), (4,8)

(5,1), (5,2), (5,3), (5,4), (5,5), (5,6), (5,7), (5,8)    

(6,1), (6,2), (6,3), (6,4), (6,5), (6,6), (6,7), (6,8)

(7,1), (7,2), (7,3), (7,4), (7,5), (7,6), (7,7), (7,8)      

(8,1), (8,2), (8,3), (8,4), (8,5), (8,6), (8,7), (8,8)  

We know that [tex]\text{Probability}=\frac{\text{Favourable outcomes}}{\text{Total outcomes}}[/tex]

[tex]\text{Probability of odd on both solid}=\frac{16}{64}[/tex]

[tex]\text{Probability of odd on both solid}=\frac{1}{4}[/tex]

Hence, the probability that an odd number is rolled on  both solids is [tex]\frac{1}{4}[/tex].

A wire is first bent into the shape of a square. Each side of the square is 9cm long. Then the wire is unbent and reshaped into a rectangle. If the length of the rectangle is 13cm, what is its width

Answers

Answer:

5 cm

Step-by-step explanation:

the perimeter of a square with sides of 9 cm is 36 cm so the rectangle must have the same perimeter

if the length of the rectangle is 13cm, its opposite side is also 13cm

add 13 + 13 to get 26

let 'n' = width of rectangle

perimeter = 26 + n + n

36 = 26 + 2n

2n = 10

n = 5

If the length of the rectangle is 13 cm then the width of the rectangle will be equal to 5 cm.

What is the perimeter?

A shape's perimeter is the whole distance encircling it. It is the perimeter or length of the contour of any two-dimensional geometric body. The circumference of several figures could be compared based on the measurements.

As per the information given in the question,

Length of the side of the square = 8 cm

Then, use the formula of the perimeter of the square = 4 × side

= 4 × 9 = 36 cm

The length of the rectangle = 13 cm

Use the formula of the perimeter of the rectangle,

P = 2(l + w)

36 = 2(13 + w)

36 -26 = 2w

w = 10/2

w = 5 cm
