Answer:

See below for a graph

Step-by-step explanation:

Let's call the parent function g(x) = log₅(x), which has a vertical asymptote at x=0, and goes through the points (1, 0), (5, 1), (25, 2).

Then this function is

... f(x) = g(2(x+6)) +2

That is, the function is horizontally compressed by a factor of 2, shifted left 6 units, and shifted up 2 units. This moves the points listed above to ...

... (-5.5, 2), (-3.5, 3), (6.5, 4)

The graph shows the parent function and the listed points in blue, then the transformed function and the corresponding points in red.

To find the number of hours Liam volunteered during the first month, we can set up an equation using the given information. By solving the equation, we find that Liam volunteered for 15 hours during the first month.

To solve this problem, we can start by representing the number of hours Liam volunteered in the first month as x. The number of hours volunteered in the next month would be 1 2/3 times x, which can be written as (5/3)x. The total number of hours volunteered is given as 40, so we can write the equation: x + (5/3)x = 40. To solve for x, we can combine the like terms and solve the resulting equation.

Combining the x terms, we get (8/3)x = 40. Solving for x, we divide both sides of the equation by 8/3: x = 40 / (8/3).

Simplifying, we have x = 40 * (3/8) = 15. Therefore, Liam volunteered for 15 hours during the first month.

By representing the number of hours in the first month as x, we can find the value of x by using the given information and solving the equation. The solution shows that Liam volunteered for 15 hours during the first month.

To solve this problem, we can set up an equation representing the total number of hours Liam volunteered. Let's represent the number of hours he volunteered in the first month as x. According to the problem, he volunteered for 1 2/3 times as many hours in the next month. So, the number of hours he volunteered in the next month is 1 2/3 x. The total number of hours is given as 40. Therefore, we have the equation:

x + 1 2/3 x = 40

To solve for x, we can simplify the equation by converting 1 2/3 to an improper fraction. This gives us:

5/3 x + 1 2/3 x = 40

Combining like terms, we get:

8/3 x = 40

To solve for x, we can multiply both sides of the equation by the reciprocal of 8/3, which is 3/8. This gives us:

x = (40)(3/8) = 15

Therefore, Liam volunteered for 15 hours during the first month.

Step-by-step explanation:

... BO/OD = AO/OC = 3/1

Written another way, this is ...

... OD : BO = 1 : 3

Now, BD = OD + BO, so we have

... BD : BO = (OD +BO) : BO = (1 +3) : 3 = 4 : 3

That is, BD = 4/3 × BO

... BD = 4/3 × 6 cm = 8 cm

To find the length of diagonal BD in trapezoid ABCD, we set up an equation using the fact that the diagonals bisect each other. We solve for x and then substitute it into the equation for BD.

To find the length of diagonal BD in trapezoid ABCD, we can use the fact that the diagonals of a trapezoid bisect each other. Let AO = 3x and OC = x. Since the diagonals intersect at point O, we can set up the equation (3x + 6) / x = 3 / 1. Solving for x, we find that x = 1.5. Therefore, BD = 2 * x + 6 = 2 * 1.5 + 6 = 9 cm.

B)110

Step-by-step explanation:500 /11%=55

55*2=110

The interest is $110 and the amount paid to the bank is $610.

Simple interest is calculated just on the loan's principal amount, whereas compound interest is calculated on both the principal and the cumulative interest.

It is given that you decide to borrow $500 to go on a trip to whatever land. You go to the bank and borrow the money at 11% for 2 years.

A. The simple interest is,

SI = ( Principle x rate x time ) / 100

SI = ( 500 x 11 x 2 ) / 100

SI = $110

B. The amount paid to the bank after 2 years is,

Amount = P + SI

Amount = $500 + $110 = $610

Therefore, the interest is $110 and the amount paid to the bank is $610.

Answer:

  B)  Both functions have exactly three x-intercepts.

  C)  The function f(x) is an odd degree function.

  E)  The x intercepts for g(x) are (1, 0); (2, 0) and (-3/2, 0)

Step-by-step explanation:

The function f is a function of degree 3 (there are 3 x-terms in the product contributing to the highest-degree term), so is of odd degree. The leading coefficient in f(x) is the product of the coefficients of x: 1·1·2 = 2, a positive number.

For a polynomial function of odd degree, the general shape of the graph will be "/" if the leading coefficient is positive, and "\" if the leading coefficient is negative. That is, end behaviors will be opposites of each other. Function f has a positive leading coefficient, so its end behavior will be (-∞, -∞) and (+∞, +∞). Function g has end behavior that is (-∞, +∞) and (+∞, -∞), so is not the same. Apparently, g(x) has a negative leading coefficient.

The graph of g(x) shows it to have 3 x-intercepts. They can be read from the graph as (-3/2, 0), (1, 0) and (2, 0). The factoring of f(x) shows it to have 3 x-intercepts, the same number. There is an x-intercept of f(x) for each factor. (The x-intercept value is the value of x that makes the factor zero.)

The function f(x) is of odd degree and has three x-intercepts at -2, 1, and -3/2. The statements regarding the function g(x) cannot be confirmed without further information.

The function given is f(x) = (x+2)(x-1)(2x+3). The degree of the function is 3 as there are three terms multiplied together. Therefore, f(x) is an odd degree function, which makes option C correct.

The x-intercepts of the function occur where y = 0, i.e. where f(x) = 0. Solving this will give the roots or intercepts for x which are -2, 1, and -3/2. This means that the function f(x) has three x-intercepts, which makes option B correct.

Without information or a graph of function g(x), we cannot accurately answer options A, D and E. We cannot know the end behavior, the leading coefficient or the x intercepts for g(x). Therefore, only options B and C are true statements.

Answer:

a. x = 1, y = -2

Step-by-step explanation:

The given equations are 2x + 3y = -4 -------------(1)

x - 2y = 5 -----------------(2)

From the second equation, we get x = 2y + 5

Now plug in x = 2y + 5 in the first equation, we get

2(2y + 5) + 3y = - 4

4y + 10 + 3y = -4

7y + 10 = -4

7y = -14

y = -2

Now plug in y = -2 in x = 2y + 5 to find the x value.

x = 2(-2) + 5

x = -4 + 5

x = 1

Therefore, x = 1, y = -2

Step-by-step explanation:

The probabaility of rolling a number less than 3 is 2/6 = 1/3, since only two of the six numbers are less than 3.

Assuming the die rolls are independent, the probability of doing this 3 times is the product of the probabilities of doing it each time:

... (1/3)^3 = 1/27

Answer:

y=5

Step-by-step explanation:

1/3(y+7)=(y-1)

I will multiply by 3 on each side to get rid of the fractions

3*1/3(y+7)=(y-1)*3

y+7 = 3*(y-1)

Distribute the 3

y+7 = 3y -3

Subtract y from each side

y-y+7 = 3y-y-3

7 = 2y-3

Add 3 to each side

7+3 = 2y-3+3

10=2y

Divide each side by 2

10/2 = 2y/2

The expected value of store card transactions will be the product of their average value ($58) and their probability of occurrence (48%).

... $58 × 0.48 = $27.84

Transactions are either "store card" or "without a store card", so the probability of a transaction being made without a store card is

... 1 - 0.48 = 0.52

Using the same computatation as for store card expected value, the expected value of transactions made without a store card is ...

... $74 × 0.52 = $38.48

The expected value of the store's transactions is the sum of the expected values of the different ways transactions can be made:

... $27.84 +38.48 = $66.32

_____

The average value of transactions made without a store card is the weighted average of those made with another card and those made with cash or a gift card. Using c to represent the latter, this weighted sum is ...

... 74 = 0.80 × 70 + 0.20 × c

... 74 -56 = 0.20c . . . . . subtract 56

... 18/0.2 = c = 90 . . . . . divide by the coefficient of c

The average transaction made with cash or a gift card is $90.

Each expected value per transaction should be matched to the correct location on the tree diagram as shown in the image below.

In this exercise, we would use probability to make each of the decisions. The expected value for transactions made with a store card can be determined by multiplying its probability of occurrence (48%) by the average value ($58) as follows;

Expected value per transaction = 58 × 0.48

Expected value per transaction = $27.84

Since transactions are either made with a store card or without a store card, the probability of a transaction being made without a store card is given by;

Probability (without a store card) = 1 - 0.48 = 0.52

In this context, the expected value per transactions made without a store card is given by;

Expected value per transaction = 74 × 0.52

Expected value per transaction = $38.48

... $74 × 0.52 = $

For the store's expected value transactions, we would add each of the expected values calculated above;

Store's expected value transactions = 27.84 + 38.48

Store's expected value transactions = $66.32.

The average transaction value for transactions that are made with cash or a gift card can be calculated by finding the weighted average of all transactions made without a card;

74 = (0.80 × 70) + 0.20 × m

74 = 56 + 0.20m

0.20m = 74 - 56

0.20m = 18

m = 18/0.20

m = $90.
