Answer:
17
Step-by-step explanation:
k(x)=-2x^2+10x+5
k(3)=-2(3)^2+10(3)+5
k(3)=-2(9)+30+5
k(3)=-18+35
= 17
Answer:
k^2-18k+81

Step-by-step explanation:
<u>Actual question is:</u>
- logf 4(3d) + log4 1 = log4 3d
<u>Solution:</u>
- logf 4 + logf (3d) + 0 = log4 (3d)
- logf 4 + logf (3d) = log4 (3d)
<u>If we assume f = 4, then</u>
- log4 4 + log4 (3d) = log4 (3d)
- log4 4 = 0
but log4 4 = 1
Therefore the statement is False

Answer:
29 minutes
Step-by-step explanation:
43.25 = $7 + 1.25*X where X is the number of minutes he used the trampoline
36.25 = 1.25* X <--- subtracts 7 from both sides
3625 = 125 X <--- multiplies both sides by 100 to clear away the decimals
X = 3625/125 = 29
