Which equation represents a line passing through the point (8, 9) with a slope of 3?

1 answer:

3 0

Point slope form equation: y-y1=m(x-x1)

Step 1: plug in the x and y values- y-9=m(x-8)
Step 2: plug in the slope, then you have your answer- y-9=3(x-8)

The ratio of the side length of Square A to the side length of Square B is 4:9. The side length of Square A is 12 yards. What is

lubasha [3.4K]

A/B : 4/9 = 12/B
cross multiply
(4)(B) = (9)(12)
4B = 108
B = 108/4
B = 27

P = 4a...where a is the length of one side
P = 4(27)
P = 108 yds <=== perimeter of square B

Answer:

B. 16.7

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that the relationship between the side adjacent to the angle and the hypotenuse involves the cosine function:

Cos = Adjacent/Hypotenuse

Filling in the numbers from your diagram gives ...

cos(50°) = x/26

Multiplying by 26 gives x.

x = 26·cos(50°)

x ≈ 16.7
