Answer:
x=−4+√22 or x=−4−√22
Step-by-step explanation:
Substitute all values in the quadratic formula.
Solve.
Using translation concepts, the equation of g(x) is given as follows:

<h3>What is a translation?</h3>
A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s definition or in it’s domain. Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis.
For this problem, the parent function is given by:

For a horizontal compression by a factor of 1/5, we have to find f(1/5x), hence:

For a vertical stretch by a factor of 7, we have to multiply by 7, hence:

For a reflection in the y-axis, we have to find g(-x), hence:

For a translation of 10 units left, we have to find g(x + 10), hence:

For a translation of 1 unit down, we have to subtract one, hence:

Answer:
Option C
Step-by-step explanation:
ΔABC and ΔDEF are similar triangles.
By the property of similar triangles, corresponding sides of the similar triangle are proportional.



DE = 3
Perimeter of ΔDEF = Sum of measures of the sides of the triangle
= DE + EF + DF
= 3 + 3 + 5
= 11
Therefore, Option C will be the correct option.
Answer:
∠a = 1/2(95) = 47.5°
∠b = 90°
arc = (180 - 47.5 - 90)(2) = (42.5)(2) = 85°
