Answer:
f(x)= x^2 - 2, the one in red.
Step-by-step explanation:
To move a quadratic function up/down, you change the value at the very end of the formula.
So instead of f(x)= x^2 + 1, you would do f(x)= x^2 - 2, to move it down 3. This would be the one in red.
Answer:
∠ 3 = 50°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 1 is an exterior angle of the triangle, so
90° + ∠ 3 = ∠ 1
90° + ∠ 3 = 140° ( subtract 90° from both sides )
∠ 3 = 50°

Answer is 4.1</h3>
To get this answer, multiply 0.05 by 82
The 0.05 is the decimal form of 5%
You move the decimal point 2 spots to the left to go from percent form to decimal form.
Answer:
Step-by-step explanation:
From B on the ground straight up to A and then turn the corner to follow the dotted line...that is a 90 degree angle. So in order to find the angle of depression, subtract 66 from 90 to get 24 degrees. Subsequently, that is also the angle of elevation (the base angle inside the triangle) due to parallel lines and whatnot.
