Answer:
<h2>
h(x) = 0.0065x+1.25</h2>
Step-by-step explanation:
Given the time length in hours of a certain airplane flight represented by the function f(x) = 0.0025x + 0.75.
The time length of another airplane flight in hours can be represented by the function g(x) = 0.004x + 0.5.
x is the number of miles for the flight
The function that represents the sum of the flight time lengths is given as h(x) as shown;
h(x) = f(x) + g(x)
To get h(x), we will substitute the functions f(x) and g(x) into formula for function h(x) as shown below;
h(x) = (0.0025x + 0.75)+(0.004x + 0.5)
Collecting the like terms;
h(x)= 0.0025x + 0.004x + 0.75 + 0.5
h(x) = 0.0065x+1.25
This gives the sum of the flight time lengths
U=2x+3, x=u/2-3/2
u^2+8u+11=0
u1=(-8+sqrt(64-44))/2=-4+sqrt(5)
u2=-4-sqrt(5)
x1=u1/2-3/2=-7/2+sqrt(5)/2
x2=u2-3/2=-7/2-sqrt(5)/2
Answer:
The length of the rectangle is 10 inches, and the width is 4 inches.
Step-by-step explanation:
Given that the length of a rectangle is 6 inches more than the width, and the perimeter is 28 inches, the following calculation must be performed to find the length and the width:
(X + X + 6) x 2 = 28
2X + 2X + 12 = 28
4X = 28 - 12
X = 16/4
X = 4
Therefore, the length of the rectangle is 10 inches, and the width is 4 inches.
I think you have to divide 450 divided by 15 equal =30
