The cost of producing x units of a product is C dollars, where C is given by the function C = 0.25x2 - 80x + 300. What is the cost if no units are produced?
A)
$0
B)
$100
C)
$200
D)
$300 ...?
Answer:
D) $ 300
Step-by-step explanation:
Here, the cost ( in dollars ) of x products is defined by the function,
[tex]C=0.25x^2-80x+300[/tex]
Since, if the no units are produced,
x = 0,
Hence, the cost would be,
[tex]C=0.25(0)^2-80\times 0+300[/tex]
[tex]=0-0+300[/tex]
[tex]=\$ 300[/tex]
Option D is correct.
The cost is $300 if no units are produced.
To find the cost when no units are produced, which are shown by x and we need to evaluate the cost function C at x = 0. The cost function is given by [tex]C = 0.25x^2 - 80x + 300.[/tex]
Let's substitute x = 0 into the function:
[tex]C(0) = 0.25(0)^2 - 80(0) + 300[/tex]
[tex]C(0) = 0 - 0 + 300[/tex]
[tex]C(0) = 300[/tex]
Therefore, the cost when no units are produced is $300.
This corresponds to the constant term in the cost function, which represents the fixed costs that are incurred regardless of the number of units produced.

Step-by-step explanation:
air is being pumped into a spherical balloon at a rate of 100 cm^3/sec. How fast is the diameter increasing when the radius is 5 cm?
The diameter is increasing at a rate of approximately 100 / 300π cm/s when the radius is 5 cm.
Explanation:To find the rate at which the diameter is increasing, we need to differentiate the formula for the volume of a sphere with respect to time:
V = (4/3)πr^3
Where V is the volume and r is the radius.
Let's differentiate V with respect to t:
dV/dt = (4/3)π(3r^2)(dr/dt)
We know dV/dt = 100 cm^3/s and r = 5 cm, so plug in these values:
100 = (4/3)π(3(5^2))(dr/dt)
Simplifying the equation gives us:
dr/dt = 100 / (4π(3(5^2)))
dr/dt ≈ 100 / 300π
So, the diameter is increasing at a rate of approximately 100 / 300π cm/s when the radius is 5 cm.

Solve by factoring.
g^2+4g-32=0
Answer: The solution is g = 4, -8.
Step-by-step explanation: We are given to solve the following algebraic equation.
[tex]g^2+4g-32=0.[/tex]
Since the above algebraic equation is quadratic, so it will have two solutions.
The solution by the method of factorization is as follows:
[tex]g^2+4g-32=0\\\\\Rightarrow g^2+8g-4g-32=0\\\\\Rightarrow g(g+8)-4(g+8)=0\\\\\Rightarrow (g-4)(g+8)=0\\\\\Rightarrow g-4=0,~~~g+8=0\\\\\Rightarrow g=4, -8.[/tex]
Thus, the required solution is g = 4, -8.
It costs $15 for a yearly membership to a movie club at a movie theater. A movie ticket costs $5 for club members and $8 for nonmembers.
The total cost of a movie ticket for club members is $20 ($15 membership fee + $5 ticket price) and for non-members it is $8.
Explanation:To find the total cost of a movie ticket for club members and non-members, we need to consider the membership fee and the ticket price. Let's break it down:
For club members:
Membership fee: $15 per yearTicket price: $5For non-members:
Ticket price: $8To calculate the total cost for club members, we add the membership fee to the ticket price: $15 + $5 = $20.
To find the total cost for non-members, we simply use the ticket price: $8.
The system of equations representing the total cost for a club member (y) and a nonmember (y) after viewing x movies is given by:
y = 15 + 5x
y = 8x
Explanation:Let's break down the system of equations. For a club member, the total cost (y) is the sum of the membership fee ($15) and the product of the ticket price $5 and the number of movies viewed (x). This relationship is represented by the equation y = 15 + 5x.
On the other hand, for a nonmember, the total cost (y) is solely the product of the ticket price for nonmembers $8 and the number of movies viewed (x), as there is no membership fee. This is expressed by the equation y = 8x.
To find the number of movies (x) after which the total cost (y) for a club member equals the cost for a nonmember, we set the two equations equal to each other:
15 + 5x = 8x
Now, solving for x, we can determine the point at which the total cost for a club member is the same as the cost for a nonmember. This helps in understanding the break-even point where joining the movie club becomes financially advantageous, factoring in the membership fee and the reduced ticket price for club members.
The complete question of the above answer is:
Certainly, here is the complete question:
It costs $15 for a yearly membership to a movie club at a movie theater. A movie ticket costs $5 for club members and $8 for nonmembers.
a. Write a system of equations that you can use to find the number x of movies viewed after which the total cost y for a club member, including the membership fee, is the same as the cost for a nonmember.

What is the probability of rolling a number less than or equal to 8 with two dice, given that at least one of the dice must show a 6?
Final answer:
The probability of rolling a number less than or equal to 8 with two dice, given at least one die shows a 6, is 5/36, considering all the valid dice combinations that meet the criteria.
Explanation:
The probability of rolling a number less than or equal to 8 with two dice, given at least one must be a 6, is calculated by considering the possible combinations of dice that adhere to these conditions. First, we determine how many outcomes include at least one 6:
If the first die is a 6, the other die can be 1, 2, or a 3 (since 6+4 is already 10, which is greater than 8).
If the second die is a 6, the first die can again be 1, 2, or 3.
Both dice can be 6, which adds one more outcome.
These are mutually exclusive events, therefore we add their probabilities. There are 5 outs of 36 possible rolls (3+3) when the numbers can sum up to less than or equal to 8 with at least one die showing a 6 (1+6, 2+6, 3+6, 6+1, 6+2, 6+3).
The probability of rolling a number less than or equal to 8, given that at least one die shows a 6, is 5/36.
The probability of rolling a number less than or equal to 8 with two dice, given that at least one die shows a 6, is [tex]\( \frac{10}{11} \).[/tex]
To find the probability of rolling a number less than or equal to 8 with two dice, given that at least one of the dice must show a 6, we can use conditional probability.
Let's consider the outcomes where at least one die shows a 6:
- (6, 1), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)
- (1, 6), (2, 6), (3, 6), (4, 6), (5, 6)
Out of these 11 outcomes, the ones where the sum of the two dice is less than or equal to 8 are:
- (6, 1), (6, 2), (6, 3), (6, 4), (6, 5)
- (1, 6), (2, 6), (3, 6), (4, 6), (5, 6)
So, there are 10 favorable outcomes out of 11 possible outcomes when at least one die shows a 6.
Therefore, the probability of rolling a number less than or equal to 8 with two dice, given that at least one of the dice must show a 6, is [tex]\( \frac{10}{11} \).[/tex]

Answer:
the answer is A
Step-by-step explanation:
A computer can sort x objects in t seconds, as modeled by the function below:
t=0.005x^2+0.002x
How long, in seconds, will it take the computer to sort 10 objects?
Round your answer to the nearest hundredth of a second. ...?
To determine the time it takes for the computer to sort 10 objects, substitute x with 10 in the given function, resulting in 0.52 seconds, rounded to the nearest hundredth.
The student's question involves determining how long it takes a computer to sort 10 objects, given the function t = 0.005x² + 0.002x, where x is the number of objects and t is the time in seconds. To find out the time it takes to sort 10 objects, we substitute x with 10 into the function.
So, we have:
t = 0.005(10)² + 0.002(10)
t = 0.005(100) + 0.002(10)
t = 0.50 + 0.02
t = 0.52 seconds
Therefore, it takes the computer approximately 0.52 seconds to sort 10 objects, when the result is rounded to the nearest hundredth of a second.
A wooden beam 24 feet long leans against a wall and makes an angle of 71° with the ground. How high up the wall does the beam reach to the nearest foot?
The beam reaches approximately 23 feet up the wall.
Given that, a wooden beam is 24 feet in length and makes an angle of 71° with the ground.
We need to determine how high does it touches the wall,
To find the height up the wall reached by the wooden beam, we can use trigonometry.
Let's denote the height as "h".
In a right triangle formed by the wooden beam, the height "h" represents the opposite side, and the length of the beam (24 feet) represents the hypotenuse.
The angle between the ground and the beam is given as 71°.
We can use the sine function to solve for "h" since sine is defined as the ratio of the opposite side to the hypotenuse in a right triangle.
sin(71°) = h / 24
To find "h," we rearrange the equation:
h = sin(71°) × 24
Calculating this, we get:
h ≈ 0.9511 × 24 ≈ 22.8264
Rounding to the nearest foot, the beam reaches approximately 23 feet up the wall.

Explain how using equivalent ratios is like adding fractions with unlike denominators?
Final answer:
Using equivalent ratios is like adding fractions with unlike denominators as it involves finding a common value to work with.
Explanation:
Using equivalent ratios is similar to adding fractions with unlike denominators because both involve finding a common value to work with. When adding fractions, we look for a common denominator so that we can add the numerators. With equivalent ratios, we find a common multiplier to scale the ratios, which allows us to compare or combine the quantities represented by the ratios.
Here's a step-by-step process:
Convert the given ratios to fractions by writing them as a fraction with the given quantities as the numerator and denominator.
Find a common denominator for the fractions. This involves identifying the least common multiple (LCM) of the denominators.
Multiply the numerators and denominators of the fractions by the appropriate multiples to get equivalent fractions with the same denominator.
Compare or combine the quantities represented by the equivalent fractions.
