Help with question 17 pls

Step-by-step explanation:

Step 1:  Find the line

Option A

(y - y_1) = m(x - x_1)

(y - 5) = 2(x - (-4))

y - 5 = 2(x + 4)

Option C

y - 5 = 2x + 8

y = 2x + 13

Option D

2x - y = -13

-y = -13 - 2x

y = 2x + 13

I think Option A, C, D

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
