Step-by-step explanation:

Answer:

ok, yea, the above answer is correct

Step-by-step explanation:

The image below shows the graph f(x) = |x| – 4

Hope this helps! :)

The equation will be F = 3x. Then the force required to compress the spring 8 ​inches will be 24 pounds.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

A spring's length directly relates to the amount of force needed to compress it.

Let F be the force and x be the compressed length. Then the equation will be

F ∝ x

F = kx

If a force of 15 pounds is required to compress a certain spring 5 ​inches. Then the value of the variable k will be

15 = 5k

k = 15/5

k = 3 pounds per inch

Then the equation will be

F = 3x

The force required to compress the spring 8 ​inches will be

F = 3 (8)

F = 24 pounds

The force required to compress the spring 8 ​inches will be 24 pounds.

Answer:

For Canada = -0.3953

For Italy = 1.46511

For USA = -1.9069

Step-by-step explanation:

Given:

Mean μ = 29.4 days

Standard deviation σ = 8.6

Missing Data

For

Canada = 26 days

Italy = 42 days

USA = 13 days

Find:

Z scores

Computation:

Z scores = [X-μ]/σ

For Canada

Z scores = [26-29.4]/8.6

Z scores = -0.3953

For Italy

Z scores = [42-29.4]/8.6

Z scores = 1.46511

For USA

Z scores = [13-29.4]/8.6

Z scores = -1.9069

Step-by-step explanation:

Step 1: Define Systems

y = -3x - 2

5x + 2y = 15

Step 2: Solve for x

Substitution

Step 3: Solve for y

so 40 * 80 = 3,200

4 * 8 = 32

Then add the two 0's to the end

so 3,200

Answer:

The best way to solve 40x80 using mental math is to break down the problem.One example would be to solve 4x8 then add the two zeros to your answer to get 3200.

Step-by-step explanation:

The solution to the equation 1/2a + 2/3b = 50 when b = 30 is a = 60

The equation is given as

1/2a + 2/3b = 50

The value of b is given as

b = 30

So, we have

1/2a + 2/3 * 30 = 50

Evaluate the product

So, we have

1/2a + 20 = 50

Evaluate the like terms

So, we have

1/2a = 30

Multiply both sides by 2

a = 60

Hence, the solution to the equation 1/2a + 2/3b = 50 when b = 30 is a = 60

Answer:

8 to the power of 4

Step-by-step explanation:

since their are four 8, (8x8x8x8) , you have to put that into an exponent

still need proof?

8x8x8x8=4096

8 to the power of 4 = 4096

so to conclude, 8 to the power of 4 is the same thing as saying 8x8x8x8, it is jsut the exponent version

Answer:

34.5 ft squared

Step-by-step explanation:

Split the figure into a triangle and two rectangles. The two vertical lines on the figure already do that. The triangle's area is 3*3/2 because 8 - 3 - 2 = 3 is the base and the height is 3. Use b * h/2. The area of the smaller rectangle is 2 *3. The area of the larger rectangle is 8 * 3. Add the areas up: 4.5 + 6 + 24 = 34.5.

Answer:

x'1 = -1

x'2 = 8

Step-by-step explanation:

Answer:

x = - 1, x = 8

Step-by-step explanation:

Given

x² - 7x - 8 = 0 ( add 8 to both sides )

x² - 7x = 8

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(- [tex]\frac{7}{2}[/tex] )x + [tex]\frac{49}{4}[/tex] = 8 + [tex]\frac{49}{4}[/tex] = [tex]\frac{81}{4}[/tex]

(x - [tex]\frac{7}{2}[/tex] )² = [tex]\frac{81}{4}[/tex] ( take the square root of both sides )

x - [tex]\frac{7}{2}[/tex] = ± [tex]\sqrt{\frac{81}{4} }[/tex] = ± [tex]\frac{9}{2}[/tex] ( add [tex]\frac{7}{2}[/tex] to both sides )

x = [tex]\frac{7}{2}[/tex] ± [tex]\frac{9}{2}[/tex]

Thus

x = [tex]\frac{7}{2}[/tex] - [tex]\frac{9}{2}[/tex] =  [tex]\frac{-2}{2}[/tex] = - 1

x = [tex]\frac{7}{2}[/tex] + [tex]\frac{9}{2}[/tex] = [tex]\frac{16}{2}[/tex] = 8

Answer:

Therefore, the correct answer is 24,069,100.

Step-by-step explanation:

(6.91 x 10^4) = 6.91 x 10,000 (10 x 10 x 10 x 10) or 69,100.

(2.4 x 10^7) = 2.4 x 10,000,000 (10 x 10 x 10 x 10 x 10 x 10 x 10) or 24,000,000.

24,000,000 + 69,100 = 24,069,100

Therefore, the correct answer is 24,069,100.

Answer:

The answer is A linear model is a good fit for data set b but not data set a

Step-by-step explanation:

It can be concluded that data set A is linear, and data set B is not linear.

        [Y] = a + b[X] + ɛ

Given is that residuals for data set A and data set B were calculated and plotted on separate residual plots.

If the residuals for data set [A] form a pattern and the residuals for data set [B] do not form a pattern than it can be concluded that data set A is linear, and data set B is not linear.
