Answer:
4
Step-by-step explanation:
<em>When rotating a point 90 degrees counterclockwise about the origin the point A(x,y) becomes A'(-y,x). </em>
Point C has coordinates of (4, 3)
New coordinates will be C'(-3, 4)
<u>So the answer is:</u>
y-coordinate of C' is 4
Answer:
G
Step-by-step explanation:
difference between coordinates of A and C is 9 because 7-(-2) is 9, one-third of nine is 3, -2+3=1 G is 1. (sorry for poor phrasing)
the two coterminal angles to the given one are:
8.98 rad and -3.58 rad
<h3>How to find coterminal angles?</h3>
For a given angle A in radians, the family of coterminal angles is defined as:
B = A + n*(2*pi)
Where pi = 3.14 rad
Where n can be any integer number.
In this case, we have an angle of 2.7 radians, then the coterminal angles are:
B = 2.7 rad + n*(6.28 rad)
One positive is what we get if we select n = 1, then:
B = 2.7 rad + 1*(6.28 rad) = 8.98 rad.
And if we select n = -1, we get the negative coterminal angle:
B' = 2.7 rad - 1*(6.28 rad) = -3.58 rad
Then the two coterminal angles to the given one are:
8.98 rad and -3.58 rad

Answer:
y = - 5x² - 10x + 2
Step-by-step explanation:
y = - 5(x + 1)² + 7 ← expand (x + 1)² using FOIL
= - 5(x² + 2x + 1) + 7 ← distribute parenthesis by - 5
= - 5x² - 10x - 5 + 7 ← collect like terms
= -5x² - 10x + 2 ← in standard form
