The initial amount and rate of change given a table for a linear function are $332 and $22.5, respectively

The table of linear function represents the given parameter

On the table, we have the following points

(x, y) = (6, 467) and (10, 647)

The rate of change is calculated as

Rate = (y2 - y1)/(x2 - x1)

So, we have

Rate = (647 - 467)/(10 - 2)

Evaluate

Rate = 22.5

This means that the rate of change is $22.5

The initial amount is calculated as

y = m(x - x1) + y1

Where

m = 22.5

So, we have

y = 22.5(x - x1) + y1

Using one of the points, we have

y = 22.5(x - 6) + 467

Set x = 0

So, we have

y = 22.5(0 - 6) + 467

Evaluate

y = 332

Hence, the initial amount and rate of change given a table for a linear function are $332 and $22.5, respectively

Answer:

1470 in³, 716 in²

Step-by-step explanation:

The figure is a cylinder, and it's volume can be found using the following formula:

Volume of cylinder

= area of circle base ×height

= πr²h

Identify the value of r and h:

From the diagram, the radius (r) is 6 in. while the height (h) is 13 in.

Using the formula,

volume of cylinder

= π(6²)(13)

= 468π

= 1470 in³ (3 s.f.)

The surface area of a cylinder is the total area of all its faces, i.e. the sum of the area of its two circular bases and its curved surface area.

Formula

Surface area of cylinder

= 2πr² +2πrh

Surface area of cylinder

= 2(π)(6²) +2(π)(6)(13)

= 72π +156π

= 228π

The inequality which can be used to determine the number of gigabytes is 58 + 3x < 70 and the solution is  x < 4

The given parameters are

Flat cost = $58

Rate = $3 per gigabyte

Budget = Under $70

The equation is represented as:

Total cost = Flat cost + Rate * Number of gigabyte

So, we have

y = 58 + 3x

The budget is under 70

So, we have

58 + 3x < 70

Subtract 58 from both sides

So, we have

3x < 12

Divide both sides by 3

So, we have

x < 4

Hence. the inequality which can be used to determine the number of gigabytes is 58 + 3x < 70 and the solution is  x < 4

The other root of the given quadratic equation is a = ± 3/√2.

Given that, x=2 and x²+ax+12=0.

The roots of a quadratic equation are the values of the variable that satisfy the equation. They are also known as the "solutions" or "zeros" of the quadratic equation.

Now, put x=2 in x²+ax+12=0 and find the value of a.

That is, 2²+2a+12=0

⇒4+12+2a=0

⇒16+2a=0

⇒2a=-16

⇒a=-8

So, the value of a is -8.

Put (0, 6) and (4, 6) in the function y=2x²+bx+c and find the value of b and c.

⇒ 6 = 32+4b+c

⇒ -26 = 4b + 6

⇒ 4b = -32

⇒ b = -8

So, the value of b is -8 and the value of c is 6.

Put x=a (root) in the equation 2x + x/a -9 = 0 and find the other root.
