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
One mile = 5,280 feet.
Understand?
I am assuming that you want to know what is 5/6 of a mile.
(5/6)(5,280) = 5(880) = 4,400 feet.
If by IN A MILE you mean division, then we do the following:
(5,280)/(5/6) = (5,280 • 6)/5 = 6,336.
Is either one or the other because your question is honestly not too clearly stated..
Answer:
Step-by-step explanation:
-The total portion fed to the dog is 7/10 cup
- Canned-3/10
- Dry=7/10-3/10=4/10
-One week has 7 days. we multiply the dry portion per day by the number of days in a week.
Hence, Erin feed her dog 2 4/5 0r 2.8 cups of dry food
9(10+x)
To apply the distributive property, we need to multiply the number out of the parenthesis by each number inside.
9*10 = 90
9*x = 9x
9x + 90
Final answer: 9x + 90
