55+added=133
added=amount addeed per week times 6=6x
55+6x=133
minus 55 both sides
6x=78
divide both sides by 6
x=13
add 13 per week
y=13x+55
Only selections B and D give a maximum height of 13 at t=3. However, both of those functions have the height be -5 at t=0, meaning the ball was served from 5 ft below ground. This does not seem like an appropriate model.
We suspect ...
• the "correct" answers are probably B and D
• whoever wrote the problem wasn't paying attention.
I believe that A and D would be the correct answer. Because both are 30,60,90 triangles and would be congruent. The other 2 triangles only have 1 angle and their side measures are at two different places meaning they cannot be congruent.
Answer: 1481.48
Step-by-step explanation:
SI = prt
400 = p x 0.045 x 6
400 = 0.27p
P = 400 / 0.27
P = 1481.48
Answer:
x = -2.75
Step-by-step explanation:
:D
14 - 3 = 11
11 / -4 = -2.75
