A boat is heading towards a lighthouse, whose beacon-light is 139 feet above the water. The boat’s crew measures the angle of elevation to the beacon, 11 degrees

. What is the ship’s horizontal distance from the lighthouse (and the shore)? Round your answer to the nearest hundredth of a foot if necessary.

Answers

Answer 1

Using the slope concept, it is found that the ship’s horizontal distance from the lighthouse (and the shore) is of 715.09 feet.

What is a slope?

The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.

In this problem, we have that:

The vertical change is of 139 feet.The horizontal change is of d feet.The angle is of 11º.

Hence:

tan(11º) = 139/d

d = 139/tan(11º)

d = 715.09.

The ship’s horizontal distance from the lighthouse (and the shore) is of 715.09 feet.

Answers

The input value of the function h(-7) for h(x) = 5.7 - 19x is -26.6.

How to find the input value of a Function?

We are given the function;

h(x) = 5.7 - 19x

Thus;

h(-7) = 5.7 - 19(1.7)

h(-7) = 5.7 - 32.3

h(-7) = -26.6

Thus, we conclude that the input value of the function h(-7) is -26.6.

Vertically opposite angles are the same meaning u have to do:

U have to solve for k.

7k-6=2k+14 - using this equation

Minus 2k on both sides

5k-6=14

Add 6 on both sides

5k=20
Divide 5 on both sides

K=4 the answer is 4.

To double check substitute it into 7k-6 and 2k+14. They should be same values

7(4)-6=28-6=22
2(4)+14=8+14=22

So 4 is correct because when u substitute back into the equation it gives you the same value.

Hey there!

Answer :

x = -1 or x = -8 ✅

Explanation :

To solve this equation, you have to use the zero product property.

Ifa product of factors is zero, then at least one of its factors is zero.

Which means that either x + 1 = 0 or x + 8 = 0

⇒ x + 1 = 0

Subtract 1 from both sides :

⇒ x + 1 - 1 = 0 - 1

x = -1

OR

⇒x + 8 = 0

Subtract 8 from both sides :

⇒x + 8 - 8 = 0 - 8

x = -8

Therefore, x = -1 or x = -8.
