The question is not well structuredand lack some information.

Restructured:

Another submarines dissent can be modeled as Y= -250 X, where Y is the vertical position and X is the. access time in hours. How long will it take the submarine to make dissent of -200ft?.

To get the time taken to dissent -200ft., we will have to substitute

Y = -200ft into the given expression as shown;

Y = -250X

-200 =-250X

Rearrange

-250X = -200

-25X = -20

Divide both sides by -25

-25X/-25 = -20/-25

X = 20/25

X = 4/5 hrs

Convert to minutes

X = 4/5 × 60

X = 4×12

X = 48minutes

Hence submarine will take 48minutes to dissent -200ft

Brian and Emily are testing different paper airplane designs to see which will allow a plane to go the farthest. Emily folds her plane and attaches a paperclip to the front of it. After she throws the plane, it travels about fifty feet and then starts to fall to the ground. Why does the plane eventually fall to the ground?

The force of air resistance stops acting on the plane.

The plane was not designed to carry a load like a paperclip.

The force of gravity is greater than the force keeping the plane in the air.

The paperclip creates a magnetic force that attracts the plane to the ground.

y= 3/2 x - 2

Step-by-step explanation:

so you have to find the slope which would be

m =

y2 - y1

x2 - x1

then you find you points that you are using (2, 1) and (0, -2)

when you plug it in it is

-2-1

0-2

you simplify the numbers and get rid of the negatives to get m=3/2 x

then your y intercept is where your line meets the y axis or wherever x=0

so your y intercept is (0, -2) so the b = -2

A nutrition bar includes fat and protein in the ratio of 3:5. There are a total of 24 grams of fat and protein combined in the bar. If there are 9 calories per gram of fat and 4 calories per gram of protein, how many calories from fat and how many calories from protein are in the nutrition bar?

Answers

Let, amount of fat is 3x .

So, amount of protein is 5x .

It is given that sum of fat and protein is 24 grams.

3x + 5x = 24

8x = 24

x = 3 grams

Amount of fat is, F = 3×3 = 9 grams .

Amount of protein is, P = 5×3 = 15 grams.

Calories in fat, F = 9×9 = 81 calories .

Calories in protein, P = 15×4 = 90 calories .

Therefore, calories from fat and protein is 81 and 90 respectively.

Hence, this is the required solution.

Answers

Answer:

660 HM = 66000 M

Step-by-step explanation:

1 hectometer to meter = 100 meter

5 hectometer to meter = 500 meter

10 hectometer to meter = 1000 meter

20 hectometer to meter = 2000 meter

30 hectometer to meter = 3000 meter

40 hectometer to meter = 4000 meter

50 hectometer to meter = 5000 meter

75 hectometer to meter = 7500 meter

100 hectometer to meter = 10000 met

66000 m is the answer

What is the equation for the points (-2,3) (1,9) on a graph

Answers

9514 1404 393

Answer:

y -9 = 2(x -1) . . . point-slope formy = 2x +7 . . . . slope-intercept form2x -y = -7 . . . . standard form

Step-by-step explanation:

Perhaps you want the equation of the line that goes through these two points.

The slope of the line can be found using the formula ...

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

m = (9 -3)/(1 -(-2)) = 6/3 = 2

We can use one of the points to write the equation in point-slope form:

y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)

For slope 2 and point (1, 9) the equation is ...

y -9 = 2(x -1) . . . . equation in point-slope form

We can eliminate parentheses and get y by itself to put the equation into slope-intercept form.

y -9 = 2x -2

y = 2x +7 . . . . . . equation in slope-intercept form

With a little further rearranging, we can put this into standard form. We can get that by adding -7-y to both sides of the equation.

2x -y = -7 . . . . . equation in standard form
