Answer:
-4/h
Step-by-step explanation:
Y+4
plug in 3.6 for y
3.6+4
will give you the result of 7.6
If you would like to know what length of the board was cut off, you can calculate this using the following steps:
12 3/4 feet long board - 9 7/8 feet = 12 3/4 - 9 7/8 = 51/4 - 79/8 = 102/8 - 79/8 = (102 - 79) / 8 = 23/8 = 2 7/8 feet
The correct result would be B) 2 7/8 feet.
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
uh I don't unerstand that :(
