Answers

Answer 1

[tex]9.31*10^5[/tex] gallons are the total gallons of water used by the water park after adding the new ride.

To express the total gallons of water used by the water park after adding the new ride in scientific notation, we need to add the two values together and then convert them to scientific notation.

[tex]8.8*10^5[/tex] gallons + 51,000 gallons = [tex]9.31*10^5[/tex] gallons

Therefore, the total gallons of water used by the water park after adding the new ride is [tex]9.31*10^5[/tex] gallons.

At Jamie's bank, 20 bankers manage personal loans and 15 bankers manage business loans. Of those, 3 bankers manage both. If the bank only offers these two types of loans, how many bankers does it employ? A. 17 B. 32 C. 35 D. 38​

Answers

The bank employs a total of 32 bankers, and the answer is not listed among the options provided. The correct option is B.

Let's denote the number of bankers who manage only personal loans as P and the number of bankers who manage only business loans as B. Then, we can use the following information to form equations:

There are 20 bankers who manage personal loans, which means P + 3 bankers in total manage personal loans.

There are 25 bankers who manage business loans, which means B + 3 bankers in total manage business loans.

The bank has a total of X bankers.

Using these equations, we can solve for X as follows:

P + 3 = 20 (equation 1)

B + 3 = 25 (equation 2)

P + B + 3 = X (equation 3)

Solving equation 1 for P, we get P = 17.

Solving equation 2 for B, we get B = 12.

Substituting P = 17 and B = 22 into equation 3, we get:

17 + 12 + 3 = X

Simplifying, we get X = 32.

Therefore, the bank employs a total of 32 bankers, and the answer is not listed among the options provided.

Answers

The graph of the function f(x) = 5(3)ˣ - 1 is represented as the diagram given in option C.

To find the main points of the function f(x) = 5(3)ˣ - 1, we can identify its key features such as the y-intercept, x-intercept, and any asymptotes.

Y-intercept:

To find the y-intercept, we set x = 0 and evaluate the function:

f(0) = 5(3)⁰ - 1 = 4

Therefore, the y-intercept is (0,4).

Asymptotes:

There are no vertical asymptotes for this function since the base of the exponential function, 3, is positive.

In order for this series to have a limit less than 1, our numerator and denominator degree must be equal or the denominator must have the larger degree.

Find the equation of a parabola with a vertex at (-2, 6) and that passes through the (-4, -5)

Answers

Answer:

[tex]\frac{-11}{4} (x + 2)^2 + 6.[/tex]

Step-by-step explanation:

As we know that

The standard equation of a parabola with vertex at point (h,k) is given by:

[tex]y = a(x-h)^2 + k[/tex]

where (h,k) is the vertex

and "a" is a coefficient that determines the direction and shape of the parabola.

We know that the vertex of our parabola is (-2, 6),

so we can substitute those values into the equation to get:

[tex]y = a(x + 2)^2 + 6[/tex]

Now finding a.

Since the parabola passes through point (-4, -5). Substituting these coordinates into the equation, we get:

-5 = a(-4 + 2)^2 + 6

-5 =a(-2)^2+6

-5=4a +6

-5-6=4a

4a=-11

a =- 11/4

Substituting the value of an equation second, we get

[tex]\frac{-11}{4} (x + 2)^2 + 6.[/tex]

Therefore, the equation of the parabola with a vertex at (-2, 6) and passing through (-4, -5) is y =

[tex] \frac{-11}{4} (x + 2)^2 + 6[/tex]

Answer:

[tex]y=-\dfrac{11}{4}(x+2)^2+6[/tex]

Step-by-step explanation:

The vertex form of a parabola is:

[tex]\boxed{y=a(x-h)^2+k}[/tex]

where:

(h, k) is the vertex."a" is the leading coefficient.

Given the vertex is at (-2, 6), substitute h = -2 and k = 6 into the equation:

[tex]y=a(x-(-2))^2+6[/tex]

[tex]y=a(x+2)^2+6[/tex]

To find the value of a, substitute the point (-4, -5) into the equation and solve for a:

[tex]\begin{aligned}-5&=a(-4+2)^2+6\\-5&=a(-2)^2+6\\-5&=4a+6\\-5-6&=4a+6-6\\-11&=4a\\\dfrac{-11}{4}&=\dfrac{4a}{4}\\-\dfrac{11}{4}&=a\\a&=-\dfrac{11}{4}\end{aligned}[/tex]

Substitute the found value of a back into the equation:

[tex]y=-\dfrac{11}{4}(x+2)^2+6[/tex]

Therefore, the equation of a parabola with a vertex at (-2, 6) and that passes through the point (-4, -5) is:

[tex]\boxed{y=-\dfrac{11}{4}(x+2)^2+6}[/tex]

The table given above is suggestive of the relationship between the values of x and y given.

It may be inferred that x values are the input values while the y values are the output.

So the criteria for the values on the table to constitute a function is that each input value (x) must be associated with only one value of y.

DE bisects AC at point B

AC = a + 23

AB = 3a + 4

From  the definition of a bisector, point B divides AC into two equal sides, this means that

AB = BC = (1/2) * AC

Substituting the value of AC and AB

AB = 3a + 4 = (1/2) * (a + 23)

3a + 4 = (1/2) * (a + 23)

solving for a

2 * (3a + 4) = a + 23

6a + 8 = a + 23

6a - a  = 23 - 8

5a = 15

a = 3

The maximum of 1,159 m/s occurs when t = 7, and the minimum of 16 m/s occurs when t = 6.

How to calculate the value

It should be noted that upon deriving v(t), an equation of 12t² - 96t + 144 is produced. Subsequently, v'(t) must be set to zero, resulting in a quadratic equation of 12t² - 96t + 144 = 0, requiring division of both sides by 12 to produce t² - 8t + 12 = 0.

The quadratic can now be factored to obtain (t - 2)(t - 6) = 0, indicating that critical points lie on the values t = 2 and t = 6.

After calculating these values— v(1) = 100 m/s, v(2) = 64 m/s, v(6) = 16 m/s and v(7) = 1159 m/s—it is clear that the maximum of 1,159 m/s occurs when t = 7, and the minimum of 16 m/s occurs when t = 6.

The half-life of a certain element is 5 days. If you started with 948 grams of this element, how much remains after 30 days?

Answers

After 1 half-life, the amount of the element remaining is half of the original amount. After 2 half-lives, the amount remaining is half of the remaining amount after the first half-life. We can continue this pattern until we get to 30 days.

The number of half-lives in 30 days is 30/5 = 6.

So, after 1 half-life, the amount remaining is 948/2 = 474 grams.

After 2 half-lives, the amount remaining is 474/2 = 237 grams.

After 3 half-lives, the amount remaining is 237/2 = 118.5 grams.

After 4 half-lives, the amount remaining is 118.5/2 = 59.25 grams.

After 5 half-lives, the amount remaining is 59.25/2 = 29.625 grams.

After 6 half-lives, the amount remaining is 29.625/2 = 14.8125 grams.

Therefore, after 30 days, 14.8125 grams of the element remains

A rectangular aquarium measures 21 inches long by 11 inches wide by 18 inches tall. If the aquarium is filled to the 15 inch mark, what is the volume of the water in the aquarium?

Answers

The volume of water in the aquarium up to the 15 inch mark is 3465 cubic inches.

What is the volume of the water in the aquarium?

A rectangular prism is simply a three-dimensional solid shape which has six faces that are rectangles.

The volume of a rectangular prism is expressed as;

V = w × h × l

Where w is the width, h is height and l is length

The volume of water in the aquarium up to the 15 inch mark will be equal to the volume of a rectangular prism with a length of 21 inches, a width of 11 inches, and a height of 15 inches.

This is because the water level is 15 inches from the bottom of the aquarium.

Hence, the volume of water in the aquarium up to the 15 inch mark is:

V = l × w × h

V = 21 × 11 × 15

V = 3465 cubic inches

Therefore, the volume of water in the aquarium is 3465 cubic inches.

A baker produces 400 brownies a day at a cost of 25 cents per brownie. If all the brownies are sold each day, what is the minimum selling price per brownie to make a daily profit of at least $420?

Answers

The minimum selling price per brownie to make a daily profit of at least $420 is $1.30.

What is the minimum selling price per brownie to make a daily profit of at least $420?

Given that: A baker produces 400 brownies a day at a cost of 25 cents per brownie.

Let's begin by calculating the total cost of producing 400 brownies a day:

Cost per brownie = 25 cents = 0.25 dollars

Total cost = 400 × 0.25 = 100 dollars

To make a daily profit of at least $420, the total revenue should be:

Total revenue = Total cost + Minimum profit

Total revenue = 100 + 420 = 520 dollars

The minimum selling price per brownie to achieve this revenue can be calculated as:

Selling price per brownie = Total revenue / Number of brownies produced

Selling price per brownie = 520 / 400

Selling price per brownie = 1.3 dollars

Therefore, the minimum selling price is $1.30 per brownies.
