Two cargo ships are sailing a direct course into harbor. Ship A is 22 miles from harbor. Ship Bis sailing into harbor on a cours

s344n2d4d5 [400]

Answer:

The distance of ship B from the Harbor is 32.26 miles

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Equations.

I have added a visual aid of the problem. As we can see the courses of both ship to the harbor forms a triangle with ship B being the hypotenuse. Since we are given the distance of the course for ship A and the angle between both ships, we can use this information with the <u>COSINE operator</u> to solve for the length of the course of ship B.

$cos(x) = \frac{adjacent}{hypotenuse}$

$cos(47) = \frac{22miles}{hypotenuse}$ .... flip both fractions.

$\frac{1}{cos(47)} = \frac{hypotenuse}{22miles}$ .... multiply both sides by 22

$\frac{22mi}{cos(47)} = hypotenuse$

$32.26mi = hypotenuse = B$

So the distance of ship B from the Harbor is 32.26 miles

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

How do you solve this?

Novay_Z [31]

Let's solve your equation step-by-step.

−7x=−2x2+15

Step 1: Subtract -2x^2+15 from both sides.

−7x−(−2x2+15)=−2x2+15−(−2x2+15)

2x2−7x−15=0

Step 2: Factor left side of equation.

(2x+3)(x−5)=0

Step 3: Set factors equal to 0.

2x+3=0 or x−5=0

x= $\frac{-3}{2}$ or x=5

Answer:

x= $\frac{-3}{2}$ or x=5

Hope this helps

3t = 18

t = 6

3t - 6 = -12

3t = -6

t = -2
