Step-by-step explanation:

Helping in the name of Jesus.

As per the given graph, the rational function that is graphed in the given image is option B: F(x) = x(x+3)(x-3) / (x-3)(x+3) as per the factors.

Based on the graph, we can see that the function has vertical asymptotes at x = -3 and x = 3.

Option A has only one factor of (x+3) and one factor of (x-3), so it would have only one vertical asymptote at x = 3 or x = -3, but not both.

Option B has two factors of (x-3) and two factors of (x+3), so it has two vertical asymptotes at x = 3 and x = -3, which matches the graph.

Option C has only one factor of (x-3) and no factor of (x+3), so it would have only one vertical asymptote at x = 3 or x = -3, but not both.

Option D has only one factor of (x+3) and no factor of (x-3), so it would have only one vertical asymptote at x = -3 or x = 3, but not both.

Therefore, the rational function that is graphed in the given image is option B: F(x) = x(x+3)(x-3) / (x-3)(x+3).

Answer:

The correct answer is 16

Step-by-step explanation:

Answer:

C. 100

Step-by-step explanation:

Assuming that the proportion of tagged hogs in the population is the same as the proportion of tagged hogs in the sample that was later observed, we can set up a proportion to estimate the total population of wild hogs:

tagged hogs in population / total population = tagged hogs in sample / size of sample

We know that 20 wild hogs were tagged and released, and that 8 out of 40 hogs observed were tagged. So we can plug these numbers into the proportion and solve for the total population:

20 / total population = 8 / 40

Simplifying this equation, we get:

total population = (20 * 40) / 8 = 100

Therefore, the wildlife group can estimate that the total population of wild hogs in the area is 100. Answer choice C is correct.

Answer: 5/64

Step-by-step explanation:

The probability of drawing a red marble on the first draw is 4/16 = 1/4 (since there are 4 red marbles out of 16 total marbles).

After replacing the first marble, the probability of drawing a yellow marble on the second draw is 5/16 (since there are 5 yellow marbles remaining out of 16 total marbles).

Therefore, the probability of drawing a red marble and then a yellow marble is (1/4) x (5/16) = 5/64

Answer:

$97.50

Step-by-step explanation:

To calculate the sale price of the skateboard, we need to apply a discount of 35% to the original cost of $150:

Discount amount = 35% x $150 = $52.50

The sale price is the original cost minus the discount amount:

Sale price = $150 - $52.50 = $97.50

Therefore, the sale price of the skateboard after a 35% discount is $97.5

The sale price of the skateboard is $97.50.

To calculate the sale price, we need to first determine the amount of the discount, and then subtract that discount from the original price.

The discount is 35% of the original price:

Discount = 0.35 x 150 = 52.50

So the sale price is the original price minus the discount:

Sale price = 150 - 52.50 = 97.50

Okay, here are the steps to solve this problem:

1) Savings start in year 3 at $10,000.

2) Savings increase by $1,000 each year for 5 years, so years 4-8 savings are $11,000, $12,000, $13,000, $14,000, $15,000.

3) There are 8 years of savings total.

4) Interest rate is 15%.

To calculate the present value at year 0 (today), we use the following formula:

PV = FV / (1 + r)^n

Where FV is the future value, r is the interest rate, and n is the number of years.

So for year 3 savings of $10,000:

PV = $10,000 / (1 + 0.15)^3 = $8,562

For year 4 savings of $11,000:

PV = $11,000 / (1 + 0.15)^4 = $8,948

And so on...

Adding up the present values for years 3 to 8:

$8,562 + $8,948 + $9,371 + $9,820 + $10,298 + $10,796 + $11,310 + $11,842 = $80,847

Therefore, the total present value of the 8 years of savings is $80,847.

So the software is worth $80,847 today at a 15% interest rate.

The cost of renting the vehicle per mile is $0.524.

To get the cost per mile of renting a vehicle, multiply the total cost of renting the vehicle by the total number of miles driven.

The rental cost:

10 days multiplied by $29.95 per day equals $299.50.

The total rental cost is $299.50.

The mileage cost:

865 miles minus 500 free miles equals 365 miles.

365 miles multiplied by $0.25 each mile equals $91.25.

The total cost of miles is $91.25.

Finally, let's figure up the overall cost:

Total rental expense + total mileage expense + gasoline expense = $299.50 + $91.25 + $62 = $452.75

Let us now compute the cost per mile:

Cost per mile = total cost / total distance traveled = $452.75 / 865 miles = $0.524 per mile

Hence, the cost of renting the vehicle per mile is $0.524.

Answer:

79

Step-by-step explanation:

Let's start by writing out what we know:

A = 647 in base-n

A = 513 in base-(n+2)

To find A in base-10, we need to use the place value system and the definition of each base. Let's first convert A to base-10 using the given information.

In base-n, A is equal to:

A = 6n^2 + 4n + 7

In base-(n+2), A is equal to:

A = 5(n+2)^2 + 1(n+2) + 3

A = 5(n^2 + 4n + 4) + (n + 2) + 3

A = 5n^2 + 21n + 20

Now we have two expressions for A, so we can set them equal to each other and solve for n:

6n^2 + 4n + 7 = 5n^2 + 21n + 20

Simplifying and rearranging, we get:

n^2 + 8n + 13 = 0

Using the quadratic formula, we can solve for n:

n = (-8 ± sqrt(8^2 - 4(1)(13))) / (2(1))

n = (-8 ± 2) / 2

n = -3 or n = -5

Since n is a positive integer, we can disregard the negative solution and conclude that n = 3.

Now that we know n, we can substitute it back into the expression for A in base-n and solve for A in base-10:

A = 6n^2 + 4n + 7

A = 6(3^2) + 4(3) + 7

A = 79

Therefore, the number A written in base-10 is 79.

Using the function y = √ (x-4) has the following:

Domain: x≥−4, Range: y≥0.

Correct answer is A.

A function is a relationship between each element of a non-empty set A and at least one element of another non-empty set B. A relation f between a set A (the function's domain) and a set B is how a function is defined in mathematics (its co-domain). Anytime an A and b B exist, f = (a,b)|

The domain of the function y=√ (x-4) is restricted by the square root of a non-negative number, which means that x-4 must be greater than or equal to zero. Thus, we have:

x-4 ≥ 0

x ≥ 4

Therefore, the domain of the function is x≥4.

The range of the function is determined by the output values of the function. Since the square root of any non-negative number is always non-negative, the output values of the function y=√x-4 will always be non-negative. Thus, the range of the function is y≥0.

Therefore, the correct answer is A. Domain: x≥−4, Range: y≥0.

a. The boat is currently 60.5 miles from its pier.

b. The boat could have originally taken a bearing of either N45°E or S45°W to arrive at the current spot.

a.How to determine the distance from the boat's pier?

To determine the distance from the boat's pier, we can use the Pythagorean theorem since we have a right triangle formed by the boat's original position, the current position, and the distance traveled to reach the current position.

Let's call the distance from the boat's pier to the current position "d", and let's call the distance traveled after the turn "x".

Using trigonometry, we can see that:

sin(35°) = x/d

Rearranging this equation, we get:

x = d×sin(35°)

Now we can use the Pythagorean theorem to solve for "d":

d² = 29²+ (d×sin(35°))²

d² = 841 + 0.77d²

0.23d² = 841

d² = 3661.74

d = 60.5 miles (rounded to one decimal place)

Therefore, the boat is currently 60.5 miles from its pier.

b. How to determine the original bearing?

To determine the original bearing, we can use trigonometry again. Let's call the original bearing "θ". Then we have,

cos(θ) = 29/d

Rearranging this equation,

d = 29/cos(θ)

Now we can substitute this expression for "d" into the equation we used to solve for "x" earlier:

x = d×sin(35°)

x = (29/cos(θ))×sin(35°)

We know that after traveling this distance, the boat is currently 14.6 miles away from its original position. So we can set up another equation:

cos(θ) = 14.6/(29/cos(θ))

Simplifying, we get:

cos²(θ) = 0.5

Taking the inverse cosine of both sides,

θ = 45° or θ = 315°

Therefore, the boat could have originally taken a bearing of either N45°E or S45°W to arrive at the current spot.

Answer:

Step-by-step explanation:

(a) We know that the balance An in the nth month is given by:

An = k · An-1 - 400

where A0 = 14,000. Substituting n = 1, we get:

A1 = k · A0 - 400

A1 = k · 14,000 - 400

We also know that her uncle charges 0.9% interest per month on the balance. This means that the balance after one month should be:

A1' = A0 + 0.009 · A0 - 400

A1' = 14,000 + 0.009 · 14,000 - 400

A1' = 14,126

Setting A1 = A1', we can solve for k:

k · 14,000 - 400 = 14,126

k = 1.009

Therefore, k is approximately 1.009.

(b) To find her balance after two months, we can use the recursive formula with n = 2:

A2 = k · A1 - 400

A2 = 1.009 · 14,126 - 400

Using a calculator, we get:

A2 ≈ 14,272.34

Therefore, her balance after two months is approximately $14,272.34.

The width of the rectangular field is 80 meters and the length is 120 meters for the given perimeter 400m.

Perimeter is a mathematical term that refers to the total distance around the outside of a closed two-dimensional shape. It is the sum of the lengths of all the sides of the shape.

According to the given information:

Let's break down the information given in the question:

Length of the rectangular field is 40m greater than the width.

The perimeter of the field is 400m.

Let's denote the width of the rectangular field as 'w' meters. According to the first information, the length of the field would be 'w + 40' meters, as it is 40m greater than the width.

Now, let's use the formula for the perimeter of a rectangle, which is given by:

Perimeter = 2 * (Length + Width)

Substituting the values we have:

Perimeter = 2 * (w + 40 + w)

Perimeter = 2 * (2w + 40)

Since the given perimeter is 400m, we can set up the equation:

400 = 2 * (2w + 40)

Now we can solve for 'w' by dividing both sides of the equation by 2:

400/2 = 2w + 40

200 = 2w + 40

Next, we subtract 40 from both sides of the equation to isolate the term with 'w':

200 - 40 = 2w

160 = 2w

Finally, we divide both sides of the equation by 2 to solve for 'w':

160/2 = w

80 = w

So, the width of the rectangular field is 80 meters. And since the length is 40 meters greater than the width, the length would be:

Length = Width + 40 = 80 + 40 = 120 meters.

So, the width of the rectangular field is 80 meters and the length is 120 meters.

Answer: Andre should buy Car 2. Brainliest?

Step-by-step explanation:

To compare the gas mileage of the two cars, we need to find out how many miles each car can travel per gallon of gas.

For Car 1: y = 25x

This means that for every gallon of gas used (x), the car can travel 25 times that amount in miles (y). So, the gas mileage for Car 1 is 25 miles per gallon (mpg).

For Car 2: we can calculate the miles per gallon by dividing the total miles traveled by the number of gallons of gas used:

For 2 gallons of gas, the car can travel 60 miles. So, the gas mileage is 30 mpg (60 miles ÷ 2 gallons).

For 5 gallons of gas, the car can travel 150 miles. So, the gas mileage is 30 mpg (150 miles ÷ 5 gallons).

For 7 gallons of gas, the car can travel 210 miles. So, the gas mileage is 30 mpg (210 miles ÷ 7 gallons).

For 8 gallons of gas, the car can travel 240 miles. So, the gas mileage is 30 mpg (240 miles ÷ 8 gallons).

For 11 gallons of gas, the car can travel 330 miles. So, the gas mileage is 30 mpg (330 miles ÷ 11 gallons).

Therefore, Car 2 has a consistent gas mileage of 30 mpg.

From the above calculations, we can see that Car 2 has a better gas mileage compared to Car 1. Car 2 can travel 30 miles on a gallon of gas, while Car 1 can only travel 25 miles on a gallon of gas.

Therefore, Andre should buy Car 2 if he wants to get the best gas mileage. Car 2 can travel 5 more miles per gallon than Car 1.

Okay, let's solve this step-by-step:

a)

Length = 30 in = 2.5 ft

Width = 15 in = 1.25 ft

Height = 18 in = 1.5 ft

Volume (cubic ft) = Length x Width x Height

= 2.5 x 1.25 x 1.5 = 3.75 cubic ft

Volume (cubic yards) = 3.75 / 27 = 0.14 cubic yards

b)

Since the box volume is 3.75 cubic ft and potting soil bags are 1.5 cubic ft,

you will need 3.75 / 1.5 = 2.5 bags of soil.

Each bag weighs 11.2 lbs, so 2.5 bags will weigh 2.5 * 11.2 = 28 lbs of soil.

c)

To paint the sides of the box, you need:

Length (2 sides) = 30 in x 2 = 60 in

Width (2 sides) = 15 in x 2 = 30 in

Height (4 sides) = 18 in x 4 = 72 in

Total inches of sides = 60 + 30 + 72 = 162 in

Conversion: 162 in / 12 in = 13.5 square ft

So you will need about 14 square feet of paint.
