Answer:
<u>f</u><u>(</u><u>5</u><u>)</u><u> </u><u>=</u><u> </u><u>1</u><u>7</u><u> </u>
Step-by-step explanation:
f(x) = 3x + 2
Since the value of x is 5, we can plug it into the equation.
f(5) = 3(5) + 2
f(5) = 15 + 2
Hope this helped :)

Answer:
A cos C = 12/13
Step-by-step explanation:
cos theta = adjacent side/ hypotenuse
cos C = BC/AC
But we don't know BC, but we can find it using the Pythagorean theorem
a^2 +b^2 = c^2
5^2 +BC^2 = 13^2
25 + BC ^2 =169
Subtract 25 from each side
BC^2 = 169-25
BC ^2 = 144
Taking the square root of each side
BC =12
cos C = 12/13
