If f = {(4, 2), (6, 1), (8, 4), (10, 2), (12, 5)}, what is the range?

1 answer:

3 0

Given the function:
<span>f = {(4, 2), (6, 1), (8, 4), (10, 2), (12, 5)}
the range is all the y-values, it's not to be confuse with the domain which is all the x-values, thus the range of our function will therefore be the following set.
{2,1,4,2,5}
Answer:
</span>{2,1,4,2,5}

loris [4]

The example that I can think of is a deck of playing cards. The two events that don't have a common set would be the black card and the red card. They are mutually exclusive because there can only be two possible colors. If the card is not red, then it is black (and vice versa). There is no card that consists of both colors.

Q1. A business jet burns 300 gallons of gasoline per hour. How many gallons of gasoline will the jet burn in a three hour flight?

Let the number of gallons required in 3 hours be = x

$\frac{x}{3}=\frac{300}{1}$

$x=900$ gallons.

Answer: The business jet burns 900 gallons of gasoline in a three hour flight.

Q2. On average, one gallon of gasoline weights approximately six pounds. How many pounds does fifty gallons of gasoline weigh?

Let the weight in pounds of 50 gallons be = x

$\frac{1}{6}=\frac{50}{x}$

$x=300$ pounds

Answer: Fifty gallons of gasoline weighs 300 pounds.

Q3. For every one yard, there are thirty-six inches. Convert 2,124 inches to an equivalent number of yards.

Let the number of yards be = x

$\frac{1}{36}=\frac{x}{2124}$

$36x=2124$

$x=\frac{2124}{36}=59$ yards

Answer: 2,124 inches = 59 yards

Q4. A person who weighs 240 pounds burns 180 calories per mile of running. If a person burns thirty-six calories by running one mile, how much does the person weigh?

Let the weight of the person be = x

$\frac{240}{180}=\frac{x}{36}$

$180x=240\times36$

$180x=8640$

$x=48$ pounds

Answer: A person who weighs 48 pounds, burns thirty-six calories while running one mile.

Q5. A rice casserole recipe serves four people and requires two tablespoons of butter. How many people will the rice casserole serve if the recipe is scaled to require six tablespoons of butter?

$\frac{4}{2}=\frac{x}{6}$

$2x=24$

$x=12$

Answer: A rice casserole that requires six tablespoons of butter serves 12 people.

Motion and rate of change derivatives. Attached is the question and where I am stuck, I would really appreciate the help :)

barxatty [35]

Answer:

A. 3 < t < 9

Step-by-step explanation:

When the particle is moving to the right, the velocity is positive.

To find the velocity, take the derivative of s(t) with respect to t.

s(t) = -t³/3 + 13t²/2 − 30t

s'(t) = -t² + 13t − 30

Find when the velocity is 0.

0 = -t² + 13t − 30

0 = t² − 13t + 30

0 = (t − 3) (t − 10)

t = 3, 10

Check the sign of s'(t) in each interval.

0 < t < 3, s'(t) < 0

3 < t < 9, s'(t) > 0

The particle moves to the right when 3 < t < 9.
