What is the domain of the function y = 3 l n x graphed below?
On a coordinate plane, a curve starts in quadrant 4 and then increases up into quadrant 1. It crosses the x-axis at (1, 0).
Answers
The domain of the function y = 3 ln x is (0, ∞) .
In mathematics, the logarithmic function is the inverse of power.The domain of a function is the set of inputs or x-values on which the function is defined.The graph of the function y = 3ln x is given below .
Then , coordinate point (1, 0)
The logarithmic function y = log x has the domain x > 0 (or) (0, ∞).
This is a logarithmic function. An important property of logarithms is that the domain cannot be denied. The same is true for x=0, since the logarithm of negative numbers is undefined.

Is the slope of a linear demand curve positive or nega-
tive?
Answers
The slope of a linear demand curve is negative
The demand curve's negative slope indicates that there is an inverse link between price and demand.
It is true that the demand curve's negative slope indicates an inverse link between price and quantity desired. According to the demand curve, demand declines as prices increase and rises as prices decrease.
This statement is false since it only applies to Giffen products, where the demand curve has a positive slope and a direct correlation between price and quantity desired.
Because unit requests rise when prices decrease and decline when prices rise, the demand curve often slopes downward (i.e., is negative). Demand increases when prices are low, but demand decreases when prices are high.

Alfonso borrowed $2500 total from two different banks. One bank charged 4% simple interest, the other charged 3.5% simple interest. After one year, the amount of interest that Alfonso owed was $91.25. How much money did Alfonso borrow from each bank.
Answers
Alfonso borrowed $750 from the bank with 4% simple interest and borrowed $1,750 from the bank with 3.5% simple interest.
How do we calculate the amount borrowed?
Let:
x = amount borrowed from the bank that charged 4% simple interest
y = amount borrowed from the bank that charged 3.5% simple interest
Therefore, we have:
x + y = 2,500 ............................... (1)
0.04x + 0.035y = 91.25 ............................. (2)
From equation (1), we have:
x = 2,500 - y ....................... (3)
Substituting equation (3) into (2) and solving for y, we have:
0.04(2,500 - y) + 0.035y = 91.25
100 - 0.04y + 0.035y = 91.25
100 - 0.005y = 91.25
-0.005y = 91.25 - 100
-0.005y = -8.75
y = -8.75 / -0.005
y = $1,750
Substituting for y in equation (3), we have;
x = 2,500 - 1,750
x = $750

Answer: 1/4
Step-by-step explanation:
The easiest way to solve this is to make them all common denominators.
The common denominator for this problem is 24.
Change the denominators:
1/4 = 6/24
4/12 = 8/24
3/8 = 9/24
2/6 = 8/24
This way it is easier to see which one is smaller and closest to 0. In this case, it is 6/24 or 1/4 because 6/24 is the smallest out of all of them.

The rent option will cost 120 more dollars than the outright cost of the computer .
How to find how much more the rent to own option cost?The outright cost of the computer is $864.
The store also offers a rent to own option which will cost $41 per week for 24 weeks.
Therefore, the total cost for the rent option is as follows:
cost of the computer for rent option = 41 × 24
cost of the computer for rent option = 984 dollars
Therefore,
difference in cost = 984 - 864

Answers
The inequality that give the number of logic boards that will give a profit for the product is profit = x($479-$109)-$323,902.
Given that, a company produces a logic board for computers. The annual fixed cost for the board is $323,902, and the variable cost is $109 per board. So, we have to write an inequality which will gives the number of logic boards that will give a profit for the product, if the logic board sells for $479.
We simply use the formula that,
profit + annual fixed cost = number of logic board sold x (logic board sales price-variable cost of logic board)
Let the number of logic board sold be x.
profit + $323,902 = x($479-$109)
profit = x($479-$109)-$323,902
Therefore, we can denote the above listed information in profit = x($479-$109)-$323,902 term. This is the required answer.

Answers
The sample space for the event is given by {2,3,4}
The sample space is a collection of all possible outcomes of an experiment. The sample space is used in probability where the it represents all possible outcomes.
a) In the spinner there are only three possibilities.
The sample space is represented by {2,3,4} .
b)The favorable outcomes in this case is 2 and 4.
Hence the number of favorable outcome is 2.
c)There is only 1 unfavorable outcome which is 3.
d)The total number of possible outcomes is 3 , as we see in the sample space there are 3 numbers.
e)The probability is defined as the fraction of favorable outcome to the

The second matrix in the definition of [tex]f[/tex] is singular, since
[tex]\sin(\pi) = -\cos\left(\dfrac\pi2\right) = \tan(\pi) = 0[/tex]
[tex]\cos\left(\theta+\dfrac\pi4\right) = \sin\left(\dfrac\pi2 - \left(\theta+\dfrac\pi4\right)\right) = \sin\left(\dfrac\pi4-\theta\right)=-\sin\left(\theta-\dfrac\pi4\right)[/tex]
[tex]\cot\left(\theta+\dfrac\pi4\right) = \tan\left(\dfrac\pi2 - \left(\theta+\dfrac\pi4\right)\right) = \tan\left(\dfrac\pi4 - \theta\right) = -\tan\left(\theta-\dfrac\pi4\right)[/tex]

In other words, it's antisymmetric; [tex]A^\top=-A[/tex]. It's easy to show that [tex]\det(A)=0[/tex] if [tex]A[/tex] is 3x3 and antisymmetric.
The other determinant reduces to

Hence
[tex]f(\theta) = 1 + \sin^2(\theta) \implies f\left(\dfrac\pi2\right) = 1 + \cos^2(\theta)[/tex]
With [tex]g[/tex] defined on [tex]\left[0,\frac\pi2\right][/tex], both [tex]\sin(\theta)[/tex] and [tex]\cos(\theta)[/tex] are non-negative. So
[tex]g(\theta) = \sqrt{f(\theta)-1} + \sqrt{f\left(\dfrac\pi2-\theta\right)-1} \\\\ ~~~~ = \sqrt{\sin^2(\theta)} + \sqrt{\cos^2(\theta)} \\\\ ~~~~ = |\sin(\theta)| + |\cos(\theta)| \\\\ ~~~~ = \sin(\theta) + \cos(\theta) \\\\ ~~~~ = \sqrt2\,\sin\left(\theta + \dfrac\pi4\right)[/tex]

A car rental agency advertised renting a car for $27.95 per day and $0.25 per mile. If Greg rents this car for 3 days, how many whole miles can he drive on a $150 budget?
Answers
Answer: 264.6 miles
Step-by-step explanation: Let's put the info we got from the problem into an equation. If the car is rented for three days, we need to multiply 27.95 by 3, which will give us 83.85. Now let's use the equation 150=83.85 + 0.25x, where x represents miles. Subtract 83.85 from both sides and we get 66.15 = 0.25x. Now divide both sides by 0.25 and we get x = 264.6.
Answer:
264 miles
Step-by-step explanation:
y = 27.95x + 0.25n where:
y = budget
x = days rented
n = miles driven
150 = 27.95(3) + 0.25n
150 = 83.85 + 0.25n
150 - 83. 85 = 0.25n
66.15 = 0.25n
66.15 / 0.25 = n
n = 264.6 miles
27.95(3) + 0.25(246.6) = $150

answer to the nearest whole number.)
Answers
The tax equivalent value will be $3243. The third option is correct
Tax bracket Kent Fuller is currently in is 26 percent
Nontaxable employee benefits value: $2400
The return that a taxable benefit would need to provide in order to match the yield on a comparable tax-exempt benefit is known as the tax-equivalent value. This is very useful for investors to compare the return between a tax-free and a taxable alternative.
Finding out the tax equivalent value using the formula:
Tax equivalent value = Tax exempt value/(1 - Tax Rate)
Tax equivalent value = 2400/(1 - 0.26)
= 2400/0.74
Tax equivalent value = 3243.24 or 3243
Therefore, the tax equivalent value will be $3243. Hence, the third option is correct
