Answer:r<4/7
Step-by-step explanation:
35r-21<-35r+19
Collect like terms
35r+35r<21+19
70r<40
divide both sides by 70
70r/70<40/70
r<40/70
r<4/7
Answer: (D) <em>bottom right graph</em>
<u>Step-by-step explanation:</u>
The vertex form of a quadratic equation is: f(x) = a(x - h)² + k, where
- (h, k) is the vertex
- |a| is the vertical stretch
- sign of "a" determines the direction of the parabola
Given g(x) = (x - 3)² - 5
- vertex (h, k) = (3, -5)
- vertical stretch |a| = 1
- sign of "a" is positive so parabola points up
The only graph that satisfies all of these conditions is the bottom right.
Answer:

Step-by-step explanation:
Multiply the fractions by multiplying the numerators.

H=-16t^2+192t+0. It will have a maximum because the negative in front of the 16 indicates that the parabola will face downwards
