Answer:
8 ft
Step-by-step explanation:
h(x)=-0.0085x²+0.25x+6,
The maximum height will be at the vertex
The x coordinate is at
h = -b/2a where b is the x term coefficient and a is the x^2 term coefficient
h = -(.25)/(2(-.0085)
=14.70588235
We want to find the height so we need to substitute this into the equation
h(14.70588235)=-0.0085(14.70588235)^2+0.25(14.70588235)+6,
=-1.838235294+3.676470588+6
=7.838235293 ft
To the nearest foot
= 8 ft
Answer:
A) 684 in^2
Step-by-step explanation:
Since it needs to be painted all around the box we have to find the surface area of the box
The surface area of cuboid is
=2lw+2lh+2hw (l: length, w: width, h: height)
=2×15×12+2×6×15+2×6×12
= 684 in^2
Answer:
x = 1/3
Step-by-step explanation:
23. y=25x looks about right to me
24. for the equation I used, 2010 is 30 years from 1980, so y=25*30, our about 750,000
