Answer:
A
Step-by-step explanation:
We are given a parabola with a vertex point of (2, 1) and a <em>y-</em>intercept of <em>y</em> = 4.
And we want to determine another point on the parabola.
Recall that a parabola is symmetric along the axis of symmetry, which is the <em>x-</em>coordinate of the vertex.
Note that since the <em>y-</em>intercept of the parabola is <em>y</em> = 4, this means that a point on our parabola is (0, 4).
To get from (2, 1) to (0, 4), we move two units left and three units up.
Since the parabola is symmetric along axis of symmetry, another point on the parabola will be two units right and three units up. This yields (2 + 2, 1 + 3) or (4, 4).
Our answer is A.
<u>ANSWER</u>
Only the equation is a function
<u>EXPLANATION</u>
is graphed above with its inverse 
.
We perform the vertical line test for both the equation and its inverse.
The equation passed the vertical line hence it is a function.
However, failed the vertical line test, hence it is not a function.
The dot product will have you multiply the corresponding coordinates and add up the products
v dot w = (6*(-7)) + (7*5) + (-3*2)
v dot w = -42 + 35 - 6
v dot w = -7 - 6
v dot w = -13
Answer: -13
Answer:
x=40
Step-by-step explanation:
Both angles are equal. So the equation needs to equal 156.
Just plug in points for x until the answer is 156.
In this case, when we plug in 40, it works!
