Two ships leave port at the same time. One travels north at 70 knots (that is, 70 nautical miles per hour), and the other west a
sergeinik [125]

Answer:

99miles is more likely correct

or 114miles as knots is usually higher mileage

Step-by-step explanation:

70^2 + 70^2 = c^2

sqrt 4900 + sqrt 4900 = c^2

sq rt 9800 = c^2 = 98.9949494

99 x 1.1507794480225 = 113.927165 = 114miles if converted to 80.6m/ph

70 Knots is equivalent to 80.554561361578 Miles/Hour. How to convert from Knots to Miles/Hour The conversion factor from Knots to Miles/Hour is 1.1507794480225. To find out how many Knots in Miles/Hour, multiply by the conversion factor or use the Velocity converter.

Suppose that you are asked to find a quadratic regression to model the height of a ball above the ground after it has been throw
Fynjy0 [20]
Given yo = initial height the ball was thrown from.
Given vo = the initial velocity of the ball thrown

y = yo + (vo)t -16t^2 where t = time.

This is a parabola opening downward.

There is no y intercept as the ball is thrown upwards upwards not necessarily straight vertically.

The x-intercepts occur when the ball reaches the level the ball was thrown from or the ground.

A pizza is 14 inches in diameter. Each square inch of pizza has 14.04 calories. If each slice contains about 270 calories, how m
mr Goodwill [35]

Answer:

8 slices

Step-by-step explanation:

To answer this question, we first need to know the area covered by the pizza.

Since it is circular in shape, we use the formula for the area of a circle.

Mathematically area of a circle = pi * r^2

Here, we were given the diameter but we know that D = 2r or r = D/2. This shows that the radius would be 14/2 = 7 inches

Now the area of the pizza is 22/7 * 7 * 7 = 22 * 7 = 154 square inch

Now we proceed to calculate the amount in calories present in the pizza;

That would be 154 * 14.04 = 2162.16 calories

one slice has 270 calories; The number of slices in 2162.16 calories would be 2162.16/270 = 8.008 which is approximately 8 slices
