Answer:
So a point is (-3,-5) and the vertex is (-4,-3)
Step-by-step explanation:
This is in vertex form. Vertex form is y=a(x-h)^2+k where (h,k) is the vertex.
The vertex here is (-4,-3)... now just use a value of x to plug in (any value besides -4)
I will choice -3. This gives -2(-3+4)^2-3
f(-3)=-2(1)^2-3
f(-3)=-2-3
f(-3)=-5
So a point is (-3,-5) and the vertex is (-4,-3)
Answer:
77.75%
Step-by-step explanation:
We just have to find the sums of the product of Joey's averages and their contribution to the total grade.
Test: 0.45 * 0.8 = 0.36 = 36%
Quizzes: 0.3 * 0.85 = 0.255 = 25.5%
Homework: 0.25 * 0.65 = 0.1625 = 16.25%
Total: 36% + 25.5% + 16.25% = 77.75%
