Answer:

49

Step-by-step explanation:

The average rate of change is the ratio of the CHANGE IN Y COORDINATE and CHANGE IN X COORDINATE

In this table we are asked to determine the change in rate from x= 3 to x=5

at x =3 , y = 27

at x=5 , y=125

Hence

Change in y = 125-27 = 98

Change in x = 5-3 = 2

Hence Average Rate of Change = 98/2 = 49

Answer = 49

Answer:

12,6

Step-by-step explanation:

The explicit rule for the arithmetic sequence on which the series is based is an = 12 + (n - 1)  * 6

Series are sum of sequences. The nth term of an arithmetic series is expressed as:

an = a + (n - 1)d

where

a is the first term = 12

n is the number of terms

d is the common difference = 18 - 12 = 24 - 18 = 6

Substitute

an = 12 + (n - 1)  * 6

Hence the explicit rule for the arithmetic sequence on which the series is based is an = 12 + (n - 1)  * 6

Answer:

see explanation

Step-by-step explanation:

Since the sequence is geometric then the common ratio (r) is

r = [tex]\frac{18}{24}[/tex] = [tex]\frac{3}{4}[/tex] = 0.75

To find the next term in the sequence, multiply the previous term by r

The next 3 terms are

18 × 0.75 = 13.5

13.5 × 0.75 = 10.125

10.125 × 0.75 = 7.59375

The n th term equation of a geometric sequence is

[tex]a_{n}[/tex] = a[tex](r)^{n-1}[/tex]

where a is the first term, that is a = 24, hence

[tex]a_{n}[/tex] = 24[tex](0.75)^{n-1}[/tex]

Answer:8

Step-by-step explanation:

Solving the given equation we get  [tex]\[ -\frac{5}{4} < x < \frac{5}{2} \][/tex]

1. We start by isolating the absolute value expression by adding 7 to both sides of the inequality.

2. Then, we split the inequality into two cases based on the inner expression of the absolute value: when [tex]\( 5 - 8x \)[/tex] is non-negative and when it is negative.

3. Solving each case separately, we find the range of values for [tex]\( x \).[/tex]

4. Finally, we combine the solutions from both cases to get the final solution: [tex]\( -\frac{5}{4} < x < \frac{5}{2} \).[/tex]This means that[tex]\( x \)[/tex]lies between -5/4 and 5/2.

To solve the inequality[tex]\( |5 - 8x| - 7 < 8 \)[/tex], we'll first isolate the absolute value expression and then solve for [tex]\( x \).[/tex]

1. Add 7 to both sides:

[tex]\[ |5 - 8x| < 15 \][/tex]

2. Now, we'll split the inequality into two cases based on the inner expression of the absolute value:

Case 1: [tex]\( 5 - 8x \geq 0 \)[/tex]

[tex]\[ 5 - 8x < 15 \][/tex]

[tex]\[ -8x < 10 \][/tex]

[tex]\[ x > \frac{10}{-8} \][/tex]

[tex]\[ x > -\frac{5}{4} \][/tex]

Case 2:[tex]\( 5 - 8x < 0 \)[/tex]

[tex]\[ -(5 - 8x) < 15 \][/tex]

[tex]\[ -5 + 8x < 15 \][/tex]

[tex]\[ 8x < 20 \][/tex]

[tex]\[ x < \frac{20}{8} \][/tex]

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

So, we have two sets of solutions:

Case 1: [tex]\( x > -\frac{5}{4} \)[/tex]

Case 2:[tex]\( x < \frac{5}{2} \)[/tex]

Combining these two cases, we get:

[tex]\[ -\frac{5}{4} < x < \frac{5}{2} \][/tex]

1. We start by isolating the absolute value expression by adding 7 to both sides of the inequality.

2. Then, we split the inequality into two cases based on the inner expression of the absolute value: when \( 5 - 8x \) is non-negative and when it is negative.

3. Solving each case separately, we find the range of values for \( x \).

4. Finally, we combine the solutions from both cases to get the final solution: [tex]\( -\frac{5}{4} < x < \frac{5}{2} \).[/tex] This means that [tex]\( x \)[/tex] lies between -5/4 and 5/2.

Solve |5-8x| -7 < 8

Answer:

y = 5x + 29

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = 5x + 2 is in this form with slope m = 5

• Parallel lines have equal slopes, hence

y = 5x + c ← is the partial equation of the parallel line

To find c substitute (- 6, - 1) into the partial equation

- 1 = - 30 + c ⇒ c = - 1 + 30 = 29, thus

y = 5x + 29 ← in slope- intercept form

Answer:

The correct answer is option B.  30°

Step-by-step explanation:

Points to remember

The central angle of an arc is double the value of arc subtended on the the other part of the circle

From the figure we can see a circle with center F.

It is given that, mAB = mBC = mCD, means that, central angles of all these three arcs are equal.

To find the m<AFB

Fro the figure we get,m<CED = 15°

Therefore central angle of arc CD = 30°

So m<AFB = 30°

Answer:

y = 4.  So this is your width.

Step-by-step explanation:

Use the distributive property to do 2(2y-3) = 2*2y-2*3 = 4y-6. So we have

4y-6+2y = 18.  Combine like terms 4y and 2y to get 6y.

6y-6 = 18.  Add 6 to both sides to solve for 6y

6y = 24.   Divide by 6 to solve for y

y = 4.  So this is your width.

The width of the rectangle is determined to be 4 inches.

To find the width of the rectangle, we need to set up equations based on the information given. The length (L) is described as being 3 inches less than twice the width (W), so we can express that as L = 2W - 3. The perimeter (P) of a rectangle is calculated as P = 2L + 2W. We are told the perimeter is 18 inches, so we have 18 = 2(2W - 3) + 2W. Simplifying this equation, we get 18 = 4W - 6 + 2W, which combines to 18 = 6W - 6. Adding 6 to both sides gives us 24 = 6W, and dividing both sides by 6 yields W = 4 inches. Therefore, the width of the rectangle is 4 inches.

The process used here is similar to working through proportions and scale factors. For instance, if one is working with scale models, as in the miniature fish pond example, the scale factor is used to determine the dimensions in the model based on actual size dimensions. However, in this case, the given equations allowed us to find the width directly.

divide the volume value by 128

I decided 200 by 128 and voila; there is the answer.

Answer:

x<11

Step-by-step explanation:

Subtract by 2 both sides of equation.

2-2x-2>-20-2

Simplify.

-2x>-22

Multiply -1 from both sides of equation.

(-2x)(-1)<(-22)(-1)

Simplify.

2x<22

Divide by 2 from both sides of equation.

2x/2<22/2

Simplify, to find the answer.

22/2=11

x<11 is the correct answer.

To solve the inequality 2 - 2x > -20, we isolate the variable term by adding 2x to both sides, subtracting 2, and then dividing by 2 to find that the solution is x < 11.

To solve the inequality 2 - 2x > -20, we can follow these steps:

The solution to the inequality is x < 11.

Answer: 88 inches

Step-by-step explanation:

Given : A bicycle tire is 28 inches in diameter. approximately.

To find the distance traveled by the bicycle each time the wheel goes around we need to find the circumference of the tire.

The circumference of a circle : [tex]\pi d[/tex], where d is the diameter of the circle.

Now, the circumference of tire : [tex]\dfrac{22}{7} \times(28)=88[/tex]

Hence, the distance traveled by the bicycle each time the wheel goes around  =88 inches.

The wheel moves forward each time, in a single round it will cover distance of 88 inches.

Given information:

The diameter of the tire is 28 inches.

Now, if we need to find the distance covered by the tire in one round, we need to understand that the tire will cover exactly same distance as it's circumference in one round.

So, the distance will be equal to its circumference :

[tex]D=\pi\times d[/tex]

Hence, distance covered (D)

[tex]D=3.14\times 28\\D=88[/tex]

Hence, when the wheel move forward each time the in a single round it will cover 88 inches.

Answer:

see explanation

Step-by-step explanation:

To find the y- intercept let x = 0

f(0) = 0² - 8(0) - 10 = 0 - 0 - 10 = - 10

The y- intercept is (0, - 10)

To find the x- intercepts let f(x) = 0, that is

2x² - 8x - 10 = 0 ( divide through by 2 )

x² - 4x - 5 = 0

Consider the factors of the constant term (- 5) which sum to give the coefficient of the x- term (- 4)

The factors are - 5 and + 1, since

- 5 × 1 = - 5 and - 5 + 1 = - 4, hence

(x - 5)(x + 1) = 0

Equate each factor to zero and solve for x

x - 5 = 0 ⇒ x = 5

x + 1 = 0 ⇒ x = - 1

The x- intercepts are (- 1, 0) and (5, 0)

Final answer

The y-intercept of the function f(x) = 2x²8x-10 is at (0, -10), and the x-intercepts are (-1,0) and (5,0).

To determine the y-intercept and the other x-intercept of the quadratic function f(x) = 2x²-8x-10, we can use the standard forms and properties of quadratic equations.

The y-intercept occurs when x=0. Substituting x with 0 in the function, we get f(0) = 2(0)²- 8(0) - 10 = -10. Thus, the y-intercept is at (0, -10).

To find the other x-intercept given one of them as (-1,0), we can factor the quadratic equation, or use the quadratic formula. Factoring gives us:

(2x + 2)(x - 5) = 0

2x + 2 = 0 would give us an x-intercept at x = -1, which we already have. x - 5 = 0 gives us the other x-intercept at x = 5. So, the other x-intercept is at (5,0).

Step-by-step explanation:

because of how the h is horizontal that is the x value and the k is vertical making it the y value.

(pls mark brainliest)

The vertex gets shifted by h units horizontally and k units vertically.

The parabola is defined by

y = a(x - h)² + k

has its vertex at (h,k).

After a shift by h units right, followed by a shift of k units vertically, the parabola is defined by

y = a(x - 2h)² + 2k

which has its vertex at (2h, 2k).

∴ (h,k).

Vertex Form of the Equation of a Parabola: The equation y=a(x−h)2+k y = a ( x − h ) 2 + k of a parabola is said to be in vertex form because the vertex can be determined by examining the equation: (h,k) is the vertex.

The equation of a parabola can be written in two basic forms: Form 1: y = a( x – h) 2 + k. Form 2: x = a( y – k) 2 + h.

A parabola is nothing but a U-shaped plane curve. Any point on the parabola is equidistant from a fixed point called the focus and a fixed straight line known as the directrix. Terms related to Parabola.
