Akim ran 69.75 miles in the course of 18 days.
Answer:
The degree is 7 and the leading coefficient is -21.
Step-by-step explanation:
The degree of an equation is found using the highest exponent on the variable in the equation.
-12-8x^2+5x-21x^7 has the term x^7 so its degree is 7
The leading coefficient is the coefficient of the term with the highest degree. The coefficient of x^7 is -21.
Y = 5
x = 4
Multiply both variables by 8/5
y = 8
x = 32/5
Your answer is 32/5
Let k be a constant
y = kx
Plug (20, 4) into the equation
4 = 20k
Divide both sides by 20
k = 1/5
Your equation is
y = (1/5)x
Have an awesome day! :)
Answer
1. y = –2.5x – 15 (A)
2.(-6,0) (C)
Step-by-step explanation:
Its correct for Ed
5.3 minutes.
First, let's calculate the volume of the tank. That will be the area of the base multiplied by it's length. And since it's base is a circle, the area is pi*r^2. So:
V = l*pi*r^2
V = 3.5 * pi * (2.2/2)^2
V = 3.5 * pi * (1.1)^2
V = 3.5 * pi * 1.21
V = 4.235 * pi
V = 13.30464489
So the tank has a volume of about 13.3 ft^3. Now simply divide that volume
by the rate of incoming fluid. So
13.3 / 2.5 = 5.32
Rounding to 2 significant figures gives a time of 5.3 minutes.
