Jim has an annual salary of $96,000. His monthly expenses include a $2,500 mortgage payment, a $250 lease payment, $500 in minimum credit card payments, and a $425 payment on his speed boat. He also receives $1,200 in interest from his savings and other accounts each month. Calculate Jim’s DTI (debt-to-income) ratio.
a.
30%
b.
35%
c.
40%
d.
45%
Answer:
the answer is 46% which is option d.
Step-by-step explanation:
To calculate Jim's DTI (debt-to-income) ratio, we need to divide his total monthly debt payments by his gross monthly income.
His total monthly debt payments are:
$2,500 (mortgage payment)
$250 (lease payment)
$500 (credit card payments)
$425 (speed boat payment)
Total Monthly Debt Payments = $2,500 + $250 + $500 + $425 = $3,675
His gross monthly income is his annual salary of $96,000 divided by 12 months which is $8,000
DTI = Total Monthly Debt Payments / Gross Monthly Income = $3,675 / $8,000 = 0.46 or 46%.
The value of Jim's DTI (debt-to-income) ratio is 40%.
What is Debt to Income Ratio?Debt to income ratio is usually calculated as a percentage of the gross monthly debt payments divided by the gross monthly income.
Given that,
Annual salary = $96,000
Monthly income = 96000/12 = $8000
Total income per month = $8000 + $1,200 = $9,200
Monthly expenses = $2,500 + $250 + $500 + $425
= $3675
DTI = 3675 / 9,200 = 0.399 = 39.9% ≈ 40%
Hence the DTI of Jim is 40%.

Find the indefinite integral by making a change of variables. (use c for the constant of integration.) x x 6 dx
Answer:
Step-by-step explanation:
To find the indefinite integral ∫(x^6) dx by making a change of variables, we can let u = x^7. Then, we can express dx in terms of du using differentiation.
Differentiating both sides of the equation u = x^7 with respect to x, we get:
du/dx = 7x^6
dx = du / 7x^6
Substituting dx in terms of du in the integral, we have:
∫(x^6) dx = ∫(x^6) (du / 7x^6)
Simplifying the expression, the x^6 terms cancel out:
∫(x^6) dx = ∫(1 / 7) du
Now we can integrate with respect to u:
∫(1 / 7) du = (1/7) ∫ du
The indefinite integral of du is simply u, so we have:
(1/7) ∫ du = (1/7) u + c
Finally, substituting u back in terms of x, we get:
(1/7) u + c = (1/7) (x^7) + c
Therefore, the indefinite integral of x^6 dx, with the change of variables, is (1/7) (x^7) + c, where c represents the constant of integration.

At noon, Trevor and Kim start running from the same point. Trevor runs east at a speed of 8 km/h and Kim runs west at a speed of 6 km/h. At what time will they be 21 km apart?
Trevor and Kim will be situated 21 kilometers apart from each other at 1:30 PM. They will be separated by a distance of 21 km when the clock strikes 1:30 in the afternoon.
To determine at what time Trevor and Kim will be 21 km apart, we can set up a distance-time equation based on their relative speeds and distances.
Let's assume that t represents the time elapsed in hours since noon. At time t, Trevor would have traveled a distance of 8t km, while Kim would have traveled a distance of 6t km in the opposite direction.
Since they are running in opposite directions, the total distance between them is the sum of the distances they have traveled:
Total distance = 8t + 6t
We want to find the time when this total distance equals 21 km:
8t + 6t = 21
Combining like terms, we have:
14t = 21
To solve for t, we divide both sides of the equation by 14:
t = 21 / 14
Simplifying, we find:
t = 3 / 2
So, they will be 21 km apart after 3/2 hours, which is equivalent to 1 hour and 30 minutes.
Therefore, Trevor and Kim will be 21 km apart at 1:30 PM.

To create the 90% confidence interval for the average speeds on his road journey, Keith should utilise t* 1.943.
To construct a confidence interval for the mean of a sample, Keith needs to use the t-distribution with a degree of freedom equal to one less than the sample size.
Since Keith has seven days of data, the degrees of freedom (df) is

define at least three (3) sources of experimental uncertainties for the experiments and explain specifically how each would have affected the accuracy of the data.
By identifying and minimizing these uncertainties, it is possible to improve the accuracy of the data and obtain more reliable results.
Experimental uncertainties refer to the errors or variations that may occur in the process of conducting an experiment. There are several sources of experimental uncertainties that can affect the accuracy of the data, specifically:
1. Instrument uncertainties: These uncertainties arise from the limitations of the instruments used in the experiment. For example, if a measuring device has a limited resolution or if it is not properly calibrated, it can lead to inaccuracies in the measurements.
2. Operator uncertainties: These uncertainties arise from the variations in the way different people conduct the experiment. For example, if different people are measuring the same quantity, they may have different techniques, which can lead to variations in the measurements.
3. Environmental uncertainties: These uncertainties arise from the variations in the environment in which the experiment is conducted. For example, if the temperature or pressure of the environment changes during the experiment, it can affect the measurements.
Each of these sources of experimental uncertainties can affect the accuracy of the data by introducing errors or variations in the measurements. By identifying and minimizing these uncertainties, it is possible to improve the accuracy of the data and obtain more reliable results.

∂v⃗ ∂t+(v⃗ ⋅∇⃗⃗) v⃗ +1ρ∇⃗ p=g. The viscosity leads to frictional forces within the fluid. Taking the viscosity into account in the Euler equation finally leads to the Navier-Stokes equation.
For the derivation of the Navier-Stokes equations we consider a fluid element and the forces acting on it. At first we will consider only the motion of the fluid in x-direction. The motion of the fluid element is influenced by the pressure forces acting on the front and back surface of the cubic volume element.
These pressure forces basically represent normal stresses and are therefore denoted in the following by the Greek symbol σ instead of p. We will see later that in addition to the pressure forces, viscosity-related forces also act perpendicular to the surfaces and contribute to the normal stress.

The equation shown models the height of a 32-inch candle after lighting it, where m represents the time the candle has been burning, in minutes, and h represents the candle's height. h=32−14m If the candle's height is now 25 inches, exactly how many minutes has it been burning?
Answer:
0.5 minutes
Step-by-step explanation:
Since we are provided the equation and the current height of the candle (which would be 25 inches) we can simply replace this current height with the variable h and then solve the rest of the equation to find out the value of m when the height of the candle is at 25 inches.
h = 32−14m
25 = 32−14m ... subtract both sides by 32
-7 = -14m ... divide both sides by -14
0.5 = m
Finally, we can see that after 0.5 minutes the candle would have melted down to 25 inches.

The Bionic Woman gives Batman a 12 second
start in a 2 kilometre race. If the Bionic Woman
runs at 5 km/min, and Batman runs at 3 km/
min, who will win the race and by how many
seconds?
Answer:
Bionic Woman wins by 4 seconds.
Step-by-step explanation:
Given:
Speed of Batman = 3 km/min
Speed of Bionic woman = 5 km/min
Total distance = 2 km
Start given to Batman = 12 seconds
To find:
Winner of the race and by how many seconds?
Solution:
Start given to Batman = 12 second start
Let us find the Distance traveled by Batman in 12 second.
12 seconds = \(\frac{1}{5}\) minutes
\(Distance = Speed \times Time\)
\(Distance = 3 \times \frac{1}{5} = 0.6\ km\)
Hence, distance left for batman to be traveled = 2 - 0.6 = 1.4 km
Time taken by Batman = \(\frac{1.4}{3} \times 60\) seconds = 28 seconds
Distance for Bionic woman to be traveled = 2 km with 5 km/min
Time taken by Bionic Woman = \(\frac{2}{5}\) minutes = 24 seconds
Bionic woman is taking lesser time, So the winner of the race will be Bionic woman.
She will win by 28-24 = 4 seconds
So, answer is:
Bionic Woman wins by 4 seconds.
Points A, B, and C are collinear and AB:AC=2:5. Point A is located at (-3,-4), point B is located at (m,n) and point C is located at (2,6). What are the values of m and n? Show all work.
Answer:
m = -11/7
n = -8/7
Step-by-step explanation:
Here, what we want to calculate is the coordinates of the point B
Let’s consider the straight line as A B C
we can see that actually, the point B divides the line into the ratio 2:5 since AB:AC is 2:5
Thus, by using the internal division formula (section formula) with the ratio of division, we can get the coordinates of point B
Mathematically, the formula for internal division is given as follows;
B = ( (mx2 + nx1) /m + n , (my2 + ny1)/( m + n))
From the question;
m:n = 2:5
Thus m = 2, n = 5
(x1,y1) are coordinates of A
x1 = -3 , y1 = -4
(x2, y2) are coordinates of C
x2 = 2 , y2 = 6
Thus, substituting these values into the equation we have;
B ={ 2(2) + 5(-3)}/(2+5) , {2(6) + 5(-4)}/(2+5)
B = (-11/7, -8/7)
