which function is equivalent to y =5 (x+3 ^2) -8 ?
A) y = 5x^2 +30x +37
B) y=5x^2 + 6x - 2
C) y=5x^2 +30x +5
D) y= 5x^2 + 1
Answer: Below
Step-by-step explanation:
So we can start off by solving this equation.
(x + 3)² = x² + 6x + 9
5(x² + 6x + 9) = 5x² + 30x + 45
5x² + 30x + 45 - 8 = 5x² + 30x + 37
Going off of this, we can already see that A is our answer.
The expression f(x) = 12(1.035)* models the monthly growth of membership in the new drama club at a school. According to the function, what is the monthly growth rate?
Answer:
The monthly growth rate is 3.5%.
Step-by-step explanation:
The exponential growth function is given as follows:
\(y=a(1+r)^{x}\)
Here,
y = final value
a = initial value
r = growth rate
x = time taken
The provided expression for the monthly growth of membership in the new drama club at a school is:
\(f(x) = 12\cdot(1.035)^{x}\)
Comparing this function with the exponential growth function:
\(a(1+r)^{x}=12(1.035)^{x}\\\\a(1+r)^{x}=12(1+0.035)^{x}\)
Then value of r is 0.035 or 3.5%.
Thus, the monthly growth rate is 3.5%.

A ring-shaped region is shown below. Its inner radius is 15 yd. The width of the ring is 3 yd. Find the area of the shaded region. Use 3.14 for π. Do not round your answer.
Answer:
612.3 in.²
Step-by-step explanation:
Inner circle diameter = 34 in.
Inner circle radius = r = 17 in.
Outer circle diameter = 34 in. + 5 in. + 5 in. = 44 in.
Outer circle radius = R = 22 in.
The are of the ring is the area of the outer circle minus the area of the inner circle.
A = πR² - πr²
A = π(R² - r²)
A = 3.14[(22 in.)² - (17 in.)²]
A = 612.3 in.²

Answer:
B. "R is 85% of the original cost."
Step-by-step explanation:
The given equation is P - 0.15P = R, where P is the original cost of the shirt and R is the discounted price that Brandon paid.
Simplifying the equation, we get:
0.85P = R
Dividing both sides by P, we get:
0.85 = R/P
Therefore, the discounted price R is 85% of the original cost P.
So, the answer is (B) "R is 85% of the original cost."

Consider the following functions.
f(x) = 5/x+6, g(x) = x/x+6
Find (f+g)(x).
Find the domain of (f+g)(x). (Enter your answer using interval notation.)
Find (f−g)(x). Find the domain of (f−g)(x). (Enter your answer using interval notation.)
Find (fg)(x).
Find the domain of (fg)(x). (Enter your answer using interval notation.)
Find (f/g )(x).
Find the domain of (f/g)(x). (Enter your answer using interval notation.)
The domain of (f / g)(x) is all real numbers except x = 0. In interval notation, it can be written as (-∞, 0) ∪ (0, ∞).
To find (f + g)(x), we need to add the functions f(x) and g(x):
f(x) = 5/(x + 6)
g(x) = x/(x + 6)
(f + g)(x) = f(x) + g(x) = 5/(x + 6) + x/(x + 6)
To combine the fractions, we need a common denominator, which is (x + 6):
(f + g)(x) = (5 + x)/(x + 6)
Next, let's find the domain of (f + g)(x). The only restriction on the domain would be any value of x that makes the denominator (x + 6) equal to zero. However, there is no such value in this case.
So, the domain of (f + g)(x) is all real numbers, or (-∞, ∞) in interval notation.
To find (f - g)(x), we need to subtract the function g(x) from f(x):
(f - g)(x) = f(x) - g(x) = 5/(x + 6) - x/(x + 6)
Again, we need a common denominator, which is (x + 6):
(f - g)(x) = (5 - x)/(x + 6)
Now, let's find the domain of (f - g)(x). As before, there are no restrictions on the domain.
So, the domain of (f - g)(x) is all real numbers, or (-∞, ∞) in interval notation.
To find (f * g)(x), we need to multiply the functions f(x) and g(x):
(f * g)(x) = f(x) * g(x) = (5/(x + 6)) * (x/(x + 6))
(f * g)(x) = 5x/(x + 6)²
Next, let's find the domain of (f * g)(x). In this case, the only restriction is that the denominator (x + 6) should not equal zero.
So, the domain of (f * g)(x) is all real numbers except x = -6. In interval notation, it can be written as (-∞, -6) ∪ (-6, ∞).
To find (f / g)(x), we need to divide the function f(x) by g(x):
(f / g)(x) = f(x) / g(x) = (5/(x + 6)) / (x/(x + 6))
(f / g)(x) = 5/(x)
Now, let's find the domain of (f / g)(x). The only restriction is that the denominator x should not equal zero.
So, the domain of (f / g)(x) is all real numbers except x = 0. In interval notation, it can be written as (-∞, 0) ∪ (0, ∞).

The average number of acres burned by forest and range fires in a large county is 3,800 acrs per year, with a standard deviation of 750 acres. The distribution of the number of acres burned is normal.
a. Compute the probability that more than 4,000 acres will be burned in any year.
b. Determine the probability that fewer than 3,000 acres will be burned in any year. c. What is the probability that between 2,500 and 3,500 acres will be burned? d. In those years when more than 4,500 acres are burned, help is needed from eastern-region fire teams. Determine the probability help will be need in any year.
a. The probability of more than 4,000 acres being burned in any year is approximately 0.3957.
b. The probability of fewer than 3,000 acres being burned in any year is approximately 0.1423.
c. The probability of between 2,500 and 3,500 acres being burned in any year is approximately 0.3028.
d. The probability of help being needed in any year, given that more than 4,500 acres are burned, is approximately 0.1750.
a. We are given that the average number of acres burned per year is 3,800 acres with a standard deviation of 750 acres. We can use the normal distribution to calculate the probability of more than 4,000 acres being burned in any year.
To calculate this probability, we need to find the area under the normal curve to the right of 4,000 acres. We can standardize the value using the z-score formula:
z = (x - μ) / σ
where x is the value (4,000 acres), μ is the mean (3,800 acres), and σ is the standard deviation (750 acres).
Using the formula, we find the z-score:
z = (4,000 - 3,800) / 750 = 0.2667
Looking up the corresponding z-value in the standard normal distribution table or using a calculator, we find that the area to the right of z = 0.2667 is approximately 0.3957.
Therefore, the probability of more than 4,000 acres being burned in any year is approximately 0.3957.
b. Similarly, we can calculate the probability of fewer than 3,000 acres being burned in any year using the normal distribution.
To calculate this probability, we need to find the area under the normal curve to the left of 3,000 acres. We can standardize the value using the z-score formula:
z = (x - μ) / σ
where x is the value (3,000 acres), μ is the mean (3,800 acres), and σ is the standard deviation (750 acres).
Using the formula, we find the z-score:
z = (3,000 - 3,800) / 750 = -1.0667
Looking up the corresponding z-value in the standard normal distribution table or using a calculator, we find that the area to the left of z = -1.0667 is approximately 0.1423.
Therefore, the probability of fewer than 3,000 acres being burned in any year is approximately 0.1423.
c. To calculate the probability of between 2,500 and 3,500 acres being burned in any year, we need to find the area under the normal curve between these two values.
First, we standardize the values using the z-score formula:
z1 = (x1 - μ) / σ = (2,500 - 3,800) / 750 = -1.7333
z2 = (x2 - μ) / σ = (3,500 - 3,800) / 750 = -0.4
Next, we find the areas to the left of these z-scores using the standard normal distribution table or a calculator:
Area1 = 0.0418 (corresponding to z = -1.7333)
Area2 = 0.3446 (corresponding to z = -0.4)
To find the probability between these two values, we subtract the smaller area from the larger area:
Probability = Area2 - Area1 = 0.3446 - 0.0418 = 0.3028
Therefore, the probability of between 2,500 and 3,500 acres being burned in any year is approximately 0.3028.
d. To determine the probability of help being needed in any year when more than 4,500 acres are burned, we need to find the area under the normal curve to the right of 4,500 acres, given the average and standard deviation.
Using the same process as in part (a), we calculate the z-score:
z = (4,500 - 3,800) / 750 = 0.9333
Looking up the corresponding z-value in the standard normal distribution table or using a calculator, we find that the area to the right of z = 0.9333 is approximately 0.1750.
Therefore, the probability of help being needed in any year, given that more than 4,500 acres are burned, is approximately 0.1750.

What are the endpoints of the major axis and minor axis of the ellipse? ((x - 2) ^ 2)/36 + ((y + 3) ^ 2)/24 = 1 Drag coordinates into the boxes to correctly complete the table
From the equation of the elipse, we have that:
The endpoints of the major axis are: \(x = -4\) and \(x = 8\)The endpoints of the minor axis are: \(y = -3 - \sqrt{24}\) and \(y = -3 + \sqrt{24}\).The equation of an elipse of center \((x_0,y_0)\) has the following format:
\(\frac{(x - x_0)^2}{a^2} + \frac{(y - y_0)^2}{b^2} = 1\)
If a > b, we have that:
The endpoints of the major axis are: \(x = x_0 \pm a\)The endpoints of the minor axis are: \(y = y_0 \pm b\)In this problem, the equation is:
\(\frac{(x - 2)^2}{36} + \frac{(y + 3)^2}{24} = 1\)
Thus \(x_0 = 2, y_0 = -3, a = 6, b = \sqrt{24}\)
For the major axis:
\(x = x_0 \pm a\)
\(x = 2 \pm 6\)
\(x = 2 - 6 = -4\)
\(x = 2 + 6 = 8\)
The endpoints of the major axis are: \(x = -4\) and \(x = 8\)
For the minor axis:
\(y = y_0 \pm b\)
\(y = -3 \pm \sqrt{24}\)
\(y = -3 - \sqrt{24}\)
\(y = -3 + \sqrt{24}\)
The endpoints of the minor axis are: \(y = -3 - \sqrt{24}\) and \(y = -3 + \sqrt{24}\).

Step-by-step explanation:
A rectangular car park is being measured so that a fence can be constructed around it.The width of the car park is 12 m, correct to the nearest metre. The length of the car park is 34 m, correct to the nearest metre.What length of fence should be ordered to guarantee that there will be enough to surround the car park?
Answer:
92mStep-by-step explanation:
Since we are to construct the fence around the park, to determine the length of the fence, we will find the perimeter of the rectangular car park.
Perimeter of the car park = 2(Length + Width)
Given
Width of car park = 12m
Length of the car park = 34 m
Substituting the given data into the formula;
Perimeter of the park = 2(12+34)
Perimeter of the park = 2(46)
Perimeter of the park = 92m
Hence the length of fence that should be ordered to guarantee that there will be enough to surround the car park is 92m
Allan can make 8 pizzas in 15 minutes at the pizza restaurant where he works. If the number of pizzas varies directly with minutes, how many pizzas can Allan make in 3 hours? Please Help
Answer:
96 pizzas
Step-by-step explanation:
Allan can make 8 pizzas in 15 minutes at the pizza restaurant where he works.
We are told that;
If the number of pizzas varies directly with minutes,
P ∝ M
P = kM
Hence:
8 = 15k
k = 8/15
How many pizzas can Allan make in 3 hours?
Convert 3 hours to minutes
1 hour = 60 minutes
3 hours = x
x = 3 × 60
x = 180 minutes
Hence,
M = 180 minutes
k = 8/15
P = kM
P = 8/15 × 180
P = 96 pizzas
Therefore, Allan can make 96 pizzas in 3 hours

Riya recives a 6% commission for selling newspaper ads. If she sells 15 ads for 50$ each, how much does she earn?
Riya earns $45 in commission for selling 15 newspaper ads at $50 each.
A commission is a charge or payment given to a person or group in exchange for a good or service. When selling goods or services on behalf of a corporation, sales representatives or agents are frequently compensated with commissions in the business world. For instance, a stockbroker may receive a fee for carrying out a trade on behalf of a customer, while a real estate agent may receive a commission depending on the sale price of a property they assist in selling.
Riya receives a 6% commission for selling newspaper ads, and if she sells 15 ads for $50 each, her total earnings can be calculated as follows:
Total earnings = Total sales x Commission rate
The total sales from selling 15 ads at $50 each are:
Total sales = 15 x $50 = $750
The commission rate is 6%, which can be written as 0.06 as a decimal.
Plugging these values into the formula, we get:
Total earnings = $750 x 0.06 = $45
Therefore, Riya earns $45 in commission for selling 15 newspaper ads at $50 each.
