Answer:
Step-by-step explanation:
We will use the co-function identity for sine, where:
Since sin(21)=0.358=cos(x). This means that:
Solve for x. Add x to both sides:
Subtract 21 from both sides:
Hence:
Answer:
D is the answer. because their are three scalene triangles
For part A, you simply add the two functions a(x) and b(x). The resulting function is then (a+b)(x) = 5x +2.
For part B, you multiply the functions a(x) and b(x). Using the FOIL method, we obtain, 6x^2 -24x + 20x - 80. Simplifying, we get, (a*b)(x) = 6x^2 -4x - 80.
For part C, you replace x in the function a(x) with the expression from b(x). This results to: a[b(x)] = 3(2x - 8) +10. Simplifying, a[b(x)] = 6x - 14.
Answer:
quotient means division
(5 + d) / -2 = 14
Step-by-step explanation:
quotient means division
(5 + d) / -2 = 14
Answer:
6/5
Step-by-step explanation:
We can find the slope given two points by
m = (y2-y1)/(x2-x1)
= (1 - -5)/(7-2)
= (1+5)/(7-2)
=6/5
