What interval for the graphed function contains local maximum

Artemon [7]

Hello from MrBillDoesMath!

Answer:

The second choice, [1,2]

Discussion:

The key to this question is that we are looking for "local maximum". In the graph a local maximum, think "camel hump", occurs in the interval [1,2] -- but the global maximums, if there is one, appears to occur in x > 3 and x < -1

Thank you,

You are choosing between two plans at a discount warehouse. Plan A offers an annual membership fee of $ 90and you pay 30 %of the

Ad libitum [116K]

Answer:

Step-by-step explanation:

We have 2 linear equations, and in both, the amount of merchandise you would have to purchase is "x", the unknown. We are asked to find that value of x.

The first equation is

C(x) = .30x + 90, which says that the cost of this plan is a fixed $90, and you pay 30% of the manufacturer's cost, x.

The second equation is

C(x) = .80x + 40, which says that the cost of this plan is a fixed $40, and you pay 80% of the manufacturer's cost, x.

If we want to know when the cost of these 2 are equal to each other, we set the equations equal to each other and solve for x:

.3x + 90 = .8x + 40 so

-.5x = -50 so

x = $100

The cost for each plan will be the same at this value of x, but we will plug in 100 for x in each just to make sure we did it right:

C(100) = .3(100) + 90

C(100) = 30 + 90

C(100) = 120 and

C(100) = .8(100) + 40

C(100) = 80 + 40

C(100) = 120

You are at a family reunion and the cooler contains ten bottles of soda; four Sprite, three Dr. Pepper, and three Cherry Coke. T

Answer:

$Probability = \frac{18}{1860480}$

Step-by-step explanation:

Given

Soda = 10

Sprite = 4

Dr. Pepper = 3

Cherry Coke = 3

Required

Determine the probability of picking Dr. pepper the fourth and fifth

First, we need to sum up the number of drinks

$Total = 10 + 4 + 3 + 3$

$Total = 20$

First Selection: Dr. Pepper

$P_1= \frac{3}{20}$

Since its probability without replacement;

At this stage: Dr. Pepper = 2 and Total = 19

Second Selection: Cherry Coke

$P_2= \frac{3}{19}$

At this stage: Dr. Pepper = 2; Cherry Coke = 2 and Total = 18

Third Selection: Cherry Coke

$P_3= \frac{2}{18}$

$P_3= \frac{1}{9}$

At this stage: Dr. Pepper = 2; Cherry Coke = 1 and Total = 17

Fourth Selection: Dr. Pepper

$P_4= \frac{2}{17}$

At this stage: Dr. Pepper = 1; Cherry Coke = 1 and Total = 16

Fifth Selection: Dr. Pepper

$P_5= \frac{1}{16}$

Multiply the calculated probabilities, to give the required probability

$Probability = P_1 * P_2 * P_3 * P_4 * P_5$

$Probability = \frac{3}{20} * \frac{3}{19} * \frac{1}{9} * \frac{2}{17} * \frac{1}{16}$

$Probability = \frac{3 * 3 * 1 * 2 * 1}{20 * 19 * 18 * 17 * 16}$

$Probability = \frac{18}{1860480}$

A right triangle has a 30o angle. the leg adjacent to the 30o angle measures 25 inches. what is the length of the other leg

adelina 88 [10]

Since the triangle has a 30° angle and a right angle which is 90°, this triangle must be a 30 - 60 - 90 triangle, which is a triangle with special properties. The length of the leg adjacent to the 30° angle is equal to the √3 times x where x is the length of the angle adjacent to the 60° angle. Here is a visual representation:
