Answer:
A
Step-by-step explanation:
The exact
value of the given equation is 45 degrees or pi/4. I am hoping
that this answer has satisfied your query about and it will be able to help
you, and if you’d like, feel free to ask another question.
For x intercepts, plug in 0 for y.
0 = (x^2) - 2x - 35
*factoring* = (x-7)(x+5)
x intercepts = 7,-5
As for the vertex, you can use the equation -b/2a for the x-coordinate of the vertex
so,
x = -b/2a = -(-2)/2 = 1
then just find the y value by plugging it back in to the equation.
y = ((1)^2) - 2(1) - 35
= -36
so, vertex is at (1,-36)
1.87 is 8.5% of 22 so 8.5% of 80 is 0.085 x 80 so $6.80
-1-1 or 2-4 or 3-5 or 6-8 or 7-9 or 8-10
