Answer:
-1.15
Step-by-step explanation:
The tangent of the angle can be found as ...
tan(t) = (y-coordinate)/(x-coordinate) = -4/7
The secant of the angle is related by ...
sec(t)² = tan(t)² +1 = (-4/7)² +1 = 65/49
Then the secant of this 2nd-quadrant angle is ...
sec(t) = -√(65/49) = -(√65)/7 ≈ -1.15
Answer: 7
Step-by-step explanation: Cross multiply, so 15 times x and 21 times 5. 21 times 5 is 105 then you divide by 15 which gives you 7.
Answer:
A) f(x) = 6x + 14
Step-by-step explanation:
6(1) + 14 = 20
6 + 14 = 20
6(1.5) + 14 = 23
9 + 14 = 23
6(2) + 14 = 26
12 + 14 = 26
and so on...
