The velocity v and maximum height h of the water being pumped into the air are related by the equation
v= 
where g = 32
(a) To find the equation that will give the maximum height of the water , solve the equation for h
v=
Take square root on both sides
= 2gh
Divide by 2g on both sides
= h
So maximum height of the water h =
(b) Maximum height h= 80
velocity v= 75 ft/sec
Given g = 32
h =
h = 
h= 87.89 ft
The pump withe the velocity of 75 ft/sec reaches the maximum height of 87.89 feet. 87.86 is greater than the maximum height 80 feet.
So the pump will meet the fire department needs.
Answer:
longest side
Step-by-step explanation:
In a triangle the angle with the greatest measure is always opposite the longest side.
Coming from a 6th grader but I hope this is right!
Polynomials of degree greater than 2 can have more than one max or min value. The largest possible number of minimum or maximum points is one less than the degree of the polynomial. The following examples illustrate several possibilities.
since the degree is 4
number of possible extreme values = 4 -1 = 3
Answer:
y+3 = -11/7x(x-2)

Answer:
<em> 1005 girls</em>
Step-by-step explanation:
From the question we are given ratio of boys to girls as 7 : 29
Total ratio will be 7 + 29 = 36
Total students in the school = 1248 students
Number of girls in the school = 29/36 * 1248
Number of girls in the school = 29 * 35
Number of girls in the school = 1005
<em>Hence the approximate total number of girls in the school is 1005 girls</em>
<em></em>
<em>Note that the ratio was assumed since we are not given in question</em>
