P=5 because 3 + 5 =8. Or you can distribute and subtract 3 from both sides
3+p = 8
-3 -3

P= 5

3 + p = 8...subtract 3 from both sides
p = 8 - 3
p = 5

Find the <br> slope of 7y-x=14
Anna71 [15]
Set the equation equal to y

Add x to each side
7y=14 +x

Divide each side by 7
y=2 + x

The slope is whatever number corresponds with the variable x

In this case there is no number in front of the x which indicates that the slope is 1

exis [7]

Answer:

(a). 2399.23 meters.

(b). 1944.19 meters apart.

Step-by-step explanation:

Please find the attachment.

We have been given that standing on a cliff 380 meters above the sea, Pat sees an approaching ship and measures its angle of depression, obtaining 9 degrees.

(a) We are asked to find how far from the shore is the ship.

We know that tangent relates opposite side of a right triangle with its adjacent side.

\text{tan}=\frac{\text{Opposite}}{\text{Adjacent}}

\text{tan}(9^{\circ})=\frac{380}{x}

x=\frac{380}{\text{tan}(9^{\circ})}

x=\frac{380}{0.158384440325}=2399.22557

Therefore, the ship is approximately 2399.23 meters away from the shore.

\text{tan}(5^{\circ})=\frac{380}{x+y}

x+y=\frac{380}{\text{tan}(5^{\circ})}

x+y=\frac{380}{0.087488663526}

2399.22557+y=4343.419875

y=4343.419875-2399.22557

y=1944.194305\approx 1944.19

Therefore, the both ships are approximately 1944.19 meters apart.
