Find M A. 17 B. 16 C. 18 D. 20

mixas84 [53]

Answer:

A. 17

Step-by-step explanation:

using the cosine rule (also see attached for reference):

AB² = BC² + AC² - 2·AC·BC cos C

2·AC·BC cos C = BC² + AC² - AB²

Given that AC = 18, AB = 12 and BC = 18, substituting these into the formula

2(18)(28) cos C = 28² + 18² - 12²

1008 cos C = 964

cos C = 964/1008

cos C = 0.9563

C = cos⁻¹ 0.9563

C = 16.99 ( = 17° rounded to nearest degree)

Suppose that f(x)=3x+1....

skad [1K]

Answer:

Step-by-step explanation:

f(x) = 3x+1

f(x+h) = 3(x+h)+1 = 3x+3h+1

f(x+h) - f(x)= 3x+3h+1-3x-1 = 3h

3h/h=3
