If f(x) = 2x^2 + 1 and g(x) = 3x - 2, what is the value of f(g(-2))?
1) -127
2) -23
3) 25
4) 129
the answer is d
Using relations in a right triangle, considering c as the hypotenuse, we have that the length of side A is:
<h3>What are the relations in a right triangle?</h3>
The relations in a right triangle are given as follows:
- The sine of an angle is given by the length of the opposite side to the angle divided by the length of the hypotenuse.
- The cosine of an angle is given by the length of the adjacent side to the angle divided by the length of the hypotenuse.
- The tangent of an angle is given by the length of the opposite side to the angle divided by the length of the adjacent side to the angle.
From the information given, we can build the following relation:
cos(A) = a/c.

please explain what you meanthank u
It should be Answer D. I hope this helps. I also hope you have a great day!!!
Answer:
y = 3x - 14
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = 3x - 4 is in this form with slope m = 3
• Parallel lines have equal slopes, hence
y = 3x + c ← is the partial equation of the parallel line
To find c substitute (4, - 2) into the partial equation
- 2 = 12 + c ⇒ c = - 2 - 12 = - 14
y = 3x - 14 ← equation of parallel line
