The rate of change of distance in feet below sea level with respect to the time that the submarine travelled is; 8 ft/s

<h3>How to find the rate of change?</h3>

Finding the average rate of change of the given table is as good as finding the slope with the formula;

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

We have the following coordinates from the table;

(0, 460), (18, 604), (34, 732), (52, 876), (70, 1020)

Thus, the rate of change of distance in feet below sea level with respect to the time that the submarine travelled is;

rate of change = (604 - 460)/(18 - 0)

rate of change = 144/18

rate of change = 8 ft/s

The rate of change of distance in feet below sea level with respect to the time that the submarine travelled is; 8 ft/s

A plane travels 2,000 kilometers at a speed of 900 kilometers per hour (kph) with no wind. when a tailwind is present, the plane

Nina [5.8K]

The meaning of the y-intercept exists in the time required for the plane to cover 2,000 kilometers at a speed of 900 kilometers per hour (kph) with no wind. $2 \frac{2}{9}$ hours required for the plane to cover 2,000 kilometers at a speed of 900 kilometers per hour with no wind.

<h3>What is the meaning of the y-intercept for the function $t(x)=\frac{2,000}{900}+x $$ ?</h3>

The time it takes the plane to travel 2,000 kilometers with the tailwind, t(x), exists determined by the function

$t(x)=\frac{2,000}{900}+x $$

where x exists the increase in speed when the plane travels with the wind (tailwind).

The y-intercept exists at x=0, then

$$&t(0)=\frac{2,000}{900}+x \\$

$$&t(0)=\frac{20}{9}=2 \frac{2}{9}$ hours

$2 \frac{2}{9}$ hours required for the plane to cover 2,000 kilometers at a speed of 900 kilometers per hour with no wind.

Find the area of this shaded region.

4vir4ik [10]

Answer:9.13

Step-by-step explanation:There are three lines from the center to the sides. So they are all the same. you can see that the radius is 8 from one of the sides. You can find the area of the big triangle by knowing that 2 of the sides are 8 and 360-270=90 and that is a right triangle so we can use the pythagorean theorem to find the hypotenuse. 8^2+8^2=√128. And we can find the area by doing (8^2+8^2)/2=32 so each triangle is 16 units^2. To find out the lengths of the left triangle we have (.5*√128)^2=√32. So 8^2-32=x² x=√32. if the radius is 8 and the one side of the radius is √32 it would be 8-√32. and the other line touching the shaded area it √128 so we can say that the area of the non-little circle is the area of the whole circle-the almost circle. The area of the whole circle it 8^2*pi≈201.06. The area of the almost circle is 201.06*.75=150.79 because 270/360=.75 plus the area of the triangle (32) so the area is 182.79. So the area of the little thing is 201.06-182.79=18.27 divided by 2 =9.13

ITS IN THE PICTURE! PLEASE ANSWER CORRECTLY! I will mark brainliest if you are right :D

Ilia_Sergeevich [38]

Answer:

A, B

Step-by-step explanation:

1. A

because the intersection of the line is the solution so no solution means they do not intersect

2. B

because the points on the line that is on top of another line are all solutions and lines have infinite number of points
