The answer is A
For a function, all you really need to do is plug in any “in” number to the equation to find the “out” number
For example: plugging in 5 into equation 1 would be:
f(5) = 9(5) + 4 = 49
If you keep doing this to each of the other “in” values, you would get the “out” values
Answer:
Angle = 35°
Step-by-step explanation:
<em>The figure would form a triangle and the tree will divide it into two 90 degree triangles.</em>
<em>Height of the triangles will be 8 feet which is opposite to the angle you have to find.</em>
<em>Hypotenuse of both 90 degree triangles will be 14 feet.</em>
<u><em>To find the angle, use the sin formula</em></u>
sin (angle) = opposite/hypotenuse
angle = ?
opposite = 8
hypotenuse = 14
sin (angle) = 8/14
angle = sin inverse (0.57)
angle = 34.8° rounded off to 35°
The angle will be the same for both triangles.
Therefore, the acute angle each triangle makes with the ground is 35°.
I believe the answer to this is zero but I am not 100 percent sure.
F(x) = 3x^2 + 4x - 1
f(-3) = 3(-3)^2 + 4(-3) - 1
f(-3) = 3 * 9 - 12 - 1
f(-3) = 27 - 12 - 1
f(-3) = 15 - 1
f(-3) = 14
