Answer:

4 and 8

Step-by-step explanation:

You don't need the surface area to find the edge length of a cube. Length of edge = ∛volume

Cube 1:

Length of each edge = ∛64 = 4 in.

Area of each face = 4² = 16 in².

Surface area = 6×16 = 96 in².

Cube 2:

Length of each edge = ∛512 = 8 in

Area of each face = 8² = 64 in²

Surface area = 6×64 = 384 in²

So the surface area is in the ratio 1:4

Answer:

v = A x H = LxW xH = 7cm x 2cm x 8cm =112CM^3

Answer:

112 cm³

Step-by-step explanation:

In this question, we have to find the volume of a rectangular prism.

The formula to find the volume of a rectangular prism would be: V = L × W × H

To find the volume, plug in the values and solve.

Solve:

V = 7 × 2 × 8

V = 14 × 8

V = 112

This means that the volume of the rectangular prism is 112 cm³

Remember, volume is always represented with a exponent of 3, or cubed, in the unit.

Your answer would be 112 cm³

Answer:

[tex]g(x) = 4-4\sqrt{x}[/tex]

Step-by-step explanation:

Given

[tex]f(x) = 4\sqrt{x}+1[/tex]

1. 5 units down translation

2. Reflection in the x-axis

Required

Determine the resulting function g

1. 5 units down translation

This is defined by the rule:

A down translation is:

[tex]f'(x) = f(x) - b[/tex]

Where b is the number of units.

So, we have:

[tex]f'(x) = 4\sqrt{x} + 1 - 5[/tex]

[tex]f'(x) = 4\sqrt{x} -4[/tex]

2. Reflection in the x-axis

For a function f(x),

When reflected over the x-axis, it becomes -f(x)

So:

[tex]g(x) = -f(x)[/tex]

[tex]g(x) = -(4\sqrt{x} - 4)[/tex]

[tex]g(x) = -4\sqrt{x} +4[/tex]

[tex]g(x) = 4-4\sqrt{x}[/tex]

Answer:

At 1.5 seconds and 2.5 seconds

Step-by-step explanation:

Because this is parabolic motion, the object will reach the height of 68 feet when it's going up AND when it's coming down. In order to find out those times, you set the h on the left side of the equation equal to 68, because h stands for height.

Set that equal to 0 and factor to solve for t:

Using the quadratic formula, we get t = 1.5 and t = 2.5

The height of the object after 1 second is 229 feet.

It is required to find the height of the object after 1 second.

A polynomial is defined as an expression which is composed of variables, constants and exponents, that are combined using the mathematical operations. sums of terms of the form k⋅xⁿ, where k is any number and n is a positive integer.

Given:

The polynomial - 16t² + vt+ s, represents the height (in feet) of an object,

where

v is the initial vertical velocity (in feet per second),

s, is the initial height of the object (in feet),

t is the time in seconds.

We are given;

v(o) = 45 ft/s

s(o) = 200 ft

According to given question we have,

Thus, polynomial that represents the height is;

h(t) = -16t² + vt+ s,

After a time of 1 second, height is;

h(1) = -16(1)² + 45*1+ 200

h(1) =-16+45+200

h(1) =229 feet

Therefore, the height of the object after 1 second is 229 feet.

Answer:

The employee would earn $320 for a 40-hour work week.

Step-by-step explanation:

Given

To determine

We have to find the employee's earning earn for a 40-hour work week.

First Step

Determining the hourly rate

In order to determine the hourly rate, the first step we need to do is to divide the earning amount by the total number of hours.

Hourly rate = Total Earning amount / Total Time taken

                   = $72.00 / 9 hours

                   = $8.00 per hour

Second Step

Determining the employee's earning earn for a 40-hour work week.

As we have already determined that employee is earning $8.00 per hour.

i.e.

In order to determine the employee's earning for a 40-hour work week, all we need is to multiply the hourly rate i.e. 8 with 40.

Thus,

Earning for 40-hour work week = Hourly rate × 40

                                                     = 8.00 × 40

                                                     = $320

Therefore, the employee would earn $320 for a 40-hour work week.

Answer:

1) x/4 < 4 ⇒ x < 4*4 ⇒ x< 16

2) x + 3 ≥ 15 ⇒ x ≥ 12

3) 19 > x + 4 ⇒ 15 > x ⇒ x < 15

4) 12 ≥ 6x ⇒ 2 ≥ x ⇒ x ≤ 2

5) 7x ≤ 21 ⇒ x ≤ 3

6) 5 + x < 7 ⇒ x< 2

7) x - 5 < 17 ⇒ x < 22

8) 3x ≥ 18 ⇒ x ≥ 6

9) 20 > x + 9 ⇒ 11 > x ⇒ x < 11

Answer:

Step-by-step explanation:

Whenever a problem asks for f(x+n) or really anything, you just plug it into the OG function

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

= 3x + 6 - 5
