F(6) = 3-2 = 1
f(13) = 4-2 = 2
Rate of change:
(2-1)/(13-6) = 1/7

Answer:

Average rate for the given function is 1 / 7

Step-by-step explanation:

The average exchange rate corresponds to the ratio between the variation of the function and the variation of the variable. That is to say,

Average rate = [f (x2) - f (x1)] / (x2 -x1). Since x1 = 6 and x2 = 13, you have:

f (x1) = f (6) = sqrt (6 + 3) - 2 = 3 - 2 = 1

f (x2) = f (13) = sqrt (13 + 3) - 2 = 4 - 2 = 2

In this way,

Average rate = (2 -1) / (13 - 6) = 1/7

Container A can hold 9 cups of liquid. container B can hold 5 pints of liquid. Container c can hold 2 quarts of liquid. Whice co
nata0808 [166]
Hello!

1 cup = 0.5 pints

1 cup = 0.25 quarts

That means that 9 cups are equivalent to 4.5 pints and 2.25 quarts of liquid.

1 pint = 2 cups

1 pint = 0.5 quarts

That means that 5 pints are equivalent to 10 cups and 2.5 quarts of liquid.

1 quart = 4 cups

1 quart = 2 pints

That means that 2 quarts are equivalent to 8 cups and 4 pints of liquid.

FINAL ANSWER:

Judging by our calculations, Container B has the greatest capacity.

Rewrite the following quadratic fiction in vertex form. Then, determine if it has a maximum or minimum and say what that value i
hram777 [196]
First subtract the constant to the other side to simplify it for now
y-5=-x^2+6x
Then pull out a common factor so the coefficient is x^2
y-5=-1(x^2-6x)
Next you take 1/2 of the b value (-6) and square it to find your c value
[1/2(-6)]^2=9
After that plug 9 into your equation as your c value
y-5=-1(x^2-6x+9)
Adding the C-value (9) causes the equations to become unbalanced so you need to balance them back out by minus 9 to the other side
y-14=-1(x^2-6x+9)
Now you want to simplify the equation on the right side.
y-14=-1(x-3)^2
Finally you want to add the constant back to the right side.
y=-1(x-3)^2+14 <——— vertex form

maximum=(3,14)
