f(x) = 2x^2 - x - 10
Part A:
x-intercepts: (-2,0), (5/2,0)
Part B:
The vertex is the minimum
vertex: (1/4, -81/8)
Part C:
A:
x: -2, -1, 1/4, 1, 2
y: 0, -7, -81/8, -9, -4
B:
Answer:
5 is the mean
Step-by-step explanation:
Answer:
three equivalent ratios will be
6:22 , 9:33, 15:55
Angles RZT, RZS, and TZS form triangle RZT, so they sum to 180. Thus, we have:
110+3s+8s=180
Simplifying, we have:
11s=70
Dividing by 11, we see that:
s=70/11
Therefore, RZS=3s=210/11, and TZS=8s=560/11.
Answer:
BC = 22
Step-by-step explanation:
<b = <c given
we now know it is an isosceles triangle
therefore AC = AB
AC=AB
2x-24 = x-2
subtract x from each side
2x-x-24 = x-2-x
x-24 =-2
add 24 to each side
x-24+24 = -2+24
x = 22
side BC = x
BC = 22
