Answer:
g(x)=x^3+2x^2 - 4
Step-by-step explanation:
See attached worksheet
.48x =36 x=36/.48 x=75 So the total distance to kirk's grandmother's house was 75 miles
Answer:
5 hours cuz 75 divided by 15 is 5 or 15 x 5 is 75
Answer:
0.963
Step-by-step explanation:
It’s correct
Hello :
<span> y=-6(2.5-x)(x-5.5) = -6(2.5x -13.75 -x² +5.5x)
y = -6(-x²+8x -13.75)
y = 6x²-48x+82.5
note :
if f(x) = ax²+bx +c the vertex is the point : ( -b/2a ; f(-b/2a))
a=6 b=-48 c = 82.5 .......calculate
-b/2a = -(-48)/2(6)= 4
f(4) =6(4)²-48(4)+82.5 =96 - 192 +82.5 = -13.5</span>
