Step-by-step explanation:

You want to make a retangular prism out of cardboard. The base is 3 feet by 4 feet. The height is 2 feet. You have $5.00 and cardboard costs .10 per square foot.

a) What is the surface area of the rectangular prism?

Length × Width × Height

3 feet × 4 feet × 2 feet

= 24 square feet

b).How much will it cost to make the rectangular prism out of cardboard?

1 ft² = $0.5

24 ft² = x

Cross Multiply

x = 24ft² × $0.5/1 ft²

x = $12

It would cost $12 to make the rectangular prism out of the cardboard. You do not have sufficient money to make it

How does the graph of the function g(x)=7^x+5 differ from the graph of f(x)=7^x?

Answers

Answer:

see explanation

Step-by-step explanation:

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Given g(x) = [tex]7^{x}[/tex] + 5

Then this is the graph of f(x) shifted vertically up by 5 units

Answers

Answer:

<B = 40degrees

x = 9

Step-by-step explanation:

Find the diagram attached. From the diagram, <A = <B (corresponding angle)

5x - 5 = 3x+ 13

5x - 3x = 13 + 5

2x = 18

x = 18/2

x = 9

Since <B = 3x+13

<B = 3(9) + 13

<B = 27 + 13

<B = 40degrees

The volume of a cone is 763.02 cubic inches. The radius and height of the cone are equal. What is the radius of the cone?

Answers

Answer:

The radius of the cone is 9cm

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, a cone

The volume of a cone is expressed as

V=1/3(πr²h)

We were told that the radius r and the height h are equal

I.e r=h

Substituting h=r in the formula we have

V= 1/3(πr²*r)

V =1/3(πr³)

To find the radius r let us substitute our given 763.02cm³ (note we assume unit in cm)

763.02= 1/3(3.142r³)

763.02= (3.142r³)/3

763.02*3=3.142r³

2289.06=3.142r³

r³=2289.06/3.142

r³= 728.54

r= ³√728.54

r= 8.99cm

≈r= 9cm

Graph the line below:
y = -2x + 7

Answers

Answer:

Below.

Step-by-step explanation:

When x = 0, y = 7

and when y = 0, x = 3.5.

So plot the 2 points (0, 7) and (3.5, 0) on the grid and draw a straight line through these 2 points.

Connect these points [tex](\frac{7}{2} ,0)[/tex] and [tex](0, 7)[/tex] through a straight line. And this line represents [tex]y = -2x + 7[/tex].

How to graph a line?

To graph a line we follow the following steps:

Find the y-intercept = b of the equation y = mx + b.Plot the y-intercept. The point will be (0, b).Plot the x intercept. The point will be (x, 0). Connect those two points with your line.

According to the given question.

We have a equation of line

[tex]y = -2x+7[/tex]

The above equation of line is already in the slope intercept form.

So, the graph the line y = -2x + 7.

We first find the y intercept.

On comparing the above equation with y = mx + b, we get y = 7.

⇒ The point (0, 7) is our y intercept.

Therefore, we plot the y intercept or mark the point (0, 7) on graph.

Then we find the x intercept.

[tex]0 = -2x + 7[/tex] ( substitute y = 0)

⇒[tex]x = \frac{7 }{2}[/tex]

⇒ ([tex]\frac{7}{2}[/tex], 0 ) is our x intercept.

Connect these points [tex](\frac{7}{2} ,0)[/tex] and [tex](0, 7)[/tex] through a straight line. And this line represents [tex]y = -2x + 7[/tex].

Ocean currents - Surface ocean currents can occur on local and global scales and are typically wind-driven, resulting in both horizontal and vertical water movement. Deep ocean currents are density-driven and differ from surface currents in scale, speed, and energy. Water density is affected by the temperature, salinity (saltiness), and depth of the water. The colder and saltier the ocean water, the denser it is. The greater the density differences between different layers in the water column, the greater the mixing and circulation. Density differences in ocean water contribute to a global-scale circulation system, also called the global conveyor belt. The global conveyor belt includes both surface and deep ocean currents that circulate the globe in a 1,000-year cycle.
