Janice bought a new car. the total amount she needs to borrow is $35,000 . she plans on taking out a 5-year loan at an apr of 4%. what is the monthly payment ?
Janice's monthly payment for her 5-year, 4% APR car loan would be $626.38.
To calculate Janice's monthly payment, we first need to use the formula for calculating loan payments:
Loan Payment = Loan Amount / Discount Factor
The discount factor can be calculated using the following formula:
Discount Factor = [(1 + r)ⁿ] - 1 / [r(1 + r)ⁿ]
Where r is the monthly interest rate (4% divided by 12 months = 0.00333) and n is the total number of payments (5 years x 12 months = 60).
Plugging in the values, we get:
Discount Factor = [(1 + 0.00333)⁶⁰] - 1 / [0.00333(1 + 0.00333)⁶⁰] = 55.8389
Now, we can calculate Janice's monthly payment:

Find the absolute maximum value on (0, [infinity]) forf(x)=4x−2xlnx.
The absolute maximum value on (0, ∞) for f(x) = 4x - 2x ln x is approximately 2e (5.436), which occurs at x = e.
To find the absolute maximum value on (0, ∞) for the function f(x) = 4x - 2x ln x, we need to follow these steps:
1. Determine the critical points of the function by finding its first derivative and setting it equal to zero.
2. Check the critical points for the maximum value.
3. Verify the behavior at the boundary of the interval (0, ∞).
Step 1: Find the first derivative of f(x).
f(x) = 4x - 2x ln x
f'(x) = d/dx (4x) - d/dx (2x ln x)
Using the product and constant rules, we get:
f'(x) = 4 - 2(ln x + 1)
Step 2: Set the first derivative equal to zero to find the critical points.
4 - 2(ln x + 1) = 0
2(ln x + 1) = 4
ln x + 1 = 2
ln x = 1
Solving for x:
x = e^1
x = e (approximately 2.718)
Step 3: Check the behavior at the boundaries.
As x approaches 0 from the right, ln x approaches negative infinity, making the term -2x ln x approach infinity. Since the interval is (0, ∞), we only need to consider the behavior as x approaches ∞. As x goes to infinity, both 4x and -2x ln x will also go to infinity. However, -2x ln x will increase at a slower rate compared to 4x, so f(x) will approach infinity.
Now, we need to check the value of f(x) at the critical point x = e:
f(e) = 4e - 2e ln e
f(e) = 4e - 2e(1)
f(e) = 2e (approximately 5.436)
Thus, the absolute maximum value on (0, ∞) for f(x) = 4x - 2x ln x is approximately 5.436, which occurs at x = e.

Then:
AHEY
The AA Similarity Theorem states that if two angles of one triangle are congruent to two angles of another triangle, then the triangles are similar. We can complete the figure by drawing a line segment of length 10.5 from point A to point H.
Using this theorem, we can write the following if-then statement to describe the given illustration:
If angle RH is congruent to angle A and angle NH is congruent to angle E, then triangle PHN is similar to triangle AHE.
This means that the corresponding sides of these triangles are proportional to each other. We can use this information to complete the figure by finding the length of side AH.
Since triangle PHN is similar to triangle AHE, we can set up the following proportion:
PH/AH = HN/HE
We know that PH = 6 and HN = 8, and we want to find AH. Let x represent the length of AH.
6/x = 8/14
Cross-multiplying gives us:
6 * 14 = 8 * x
Simplifying:
84 = 8x
Dividing both sides by 8:
x = 10.5

cast by the building?
Round to one decimal place if necessary and do not include units in your answer.
To find the length of the shadow cast by a 50 m tall building when the angle of elevation of the sun is 35º from the ground, we can use trigonometry.
Step 1: Identify the known values and the unknown.
- Angle of elevation: 35º
- Building height: 50 m
- Unknown: Shadow length
Step 2: Recognize the trigonometric function to be used.
Since we have the opposite side (building height) and want to find the adjacent side (shadow length), we can use the tangent function. The formula is:
tan(angle) = opposite side/adjacent side
Step 3: Plug in the known values and solve for the unknown.
tan(35º) = 50 m / shadow length
Step 4: Rearrange the equation to isolate the shadow length.
shadow length = 50 m / tan(35º)
Step 5: Calculate the shadow length.
shadow length ≈ 50 m / 0.7002 ≈ 71.4 m
So, the length of the shadow cast by the building is approximately 71.4 m.

In mathematics, an integer is a whole number that can be positive, negative, or zero. Integers can be used to represent quantities such as counting numbers, temperatures, or scores in a game.
How to determine the two integers?Let's call the two integers x and y, where x is the larger integer and y is the smaller integer.
From the problem, we know that:
x = 29y + 40 (equation 1)
xy = 10116 (equation 2)
We can substitute equation 1 into equation 2 to get:
(29y + 40)y = 10116
Expanding and simplifying:
29[tex]y^{2}[/tex]+ 40y - 10116 = 0
We can use the quadratic formula to solve for y:
y = (-40 ± √([tex]40^{2}[/tex] - 429(-10116))) / (2×29)
y = (-40 ± √308576) / 58
y ≈ 18.95 or y ≈ -12.3
Since y is a positive integer, we can round up to 19.
Now we can use equation 1 to find x:
x = 29y + 40
x = 29(19) + 40

The graph shows the temperature (with degrees Celsius measured on the y-axis) at different times during one winter day. Negative values of x represent times earlier than noon and positive values of x represent times later than noon. How many degrees Celsius did the temperature change from 9 a.m. to noon?
The amount the temperature during the day changed between 9 a.m. and 12 noon, obtained using arithmetic operations is 8 °C increase in the temperature
What are arithmetic operations?Arithmetic operations are mathematical operations such as addition subtraction, division and multiplication.
The possible points on the scatter plot graph, obtained from the graph of a similar question posted online are; (-3, 2), (0, 10), and (4, 4)
The coordinate point on the graph corresponding to 9 a.m. is (-3, 2)
Therefore, the temperature at 9 a.m. is 2°C
The coordinate point on the graph corresponding to 12 noon is (0, 10)
Therefore, the temperature at 12 noon. is 10°C
The change in temperature between the temperature at 9 a.m. and the temperature at 12 noon = 10°C - 2°C = 8 °C (Increase in temperature)

Find the area inside the square and outside the circle use 3.14 for pi. please help
The area inside the square and outside the circle is 0.86 square units.
To find the area inside the square and outside the circle, we need to first find the area of the square and the area of the circle.
Let's assume that the square has sides of length 2 units, which means its area is:
Area of square = side^2 = 2^2 = 4 square units
Now, let's assume that the circle has a radius of 1 unit, which means its area is:
Area of circle = pi * radius^2 = 3.14 * 1^2 = 3.14 square units
To find the area inside the square and outside the circle, we need to subtract the area of the circle from the area of the square:
Area inside square and outside circle = Area of square - Area of circle
= 4 - 3.14
= 0.86 square units
Therefore, the area inside the square and outside the circle is 0.86 square units.

A sprinkler sprays water in a circle. The distance from the sprinkler to the outer edge of the circle is 2. 5 m.
What is the approximate area that is watered by the sprinkler? (Use 3. 14 as an estimate for It. )
The approximate area that is watered by the sprinkler, we need to use the formula for the area of a circle, which is A = πr^2, where A is the area, π is a constant equal to approximately 3.14, and r is the radius of the circle.
In this case, we are given that the distance from the sprinkler to the outer edge of the circle is 2.5 m, which is the radius of the circle. Therefore, we can substitute this value into the formula and get:
A = [tex]3.14 x 2.5^2[/tex]
A =[tex]19.625 m^2[/tex]
So, the approximate area that is watered by the sprinkler is 19.625 square meters. This means that any plants, grass or other vegetation within this area will receive water from the sprinkler.
It is important to note that this is only an approximation since the shape of the watered area may not be a perfect circle and the sprinkler may not spray water evenly in all directions.
Additionally, the amount of water sprayed by the sprinkler and the time it takes to water the area will also affect the actual amount of water received by the plants.

A farmer uses a lot of fertilizer to grow his crops. The farmer’s manager thinks fertilizer products from distributor A contain more of the nitrogen that his plants need than distributor B’s fertilizer does. He takes two independent samples of four batches of fertilizer from each distributor and measures the amount of nitrogen in each batch. Fertilizer from distributor A contained 21 pounds per batch and fertilizer from distributor B contained 16 pounds per batch. Suppose the population standard deviation for distributor
Calculated t-value of 6.93 is greater than the critical value, we reject the null hypothesis and conclude that there is strong evidence that the mean amount of nitrogen in distributor A's fertilizer is significantly greater than the mean amount of nitrogen in distributor B's fertilizer.
Since we do not have the population standard deviation, we will need to use the t-distribution for our hypothesis test. We are interested in testing whether the mean amount of nitrogen in distributor A's fertilizer is significantly greater than the mean amount of nitrogen in distributor B's fertilizer.
Let μA be the true mean amount of nitrogen in distributor A's fertilizer and μB be the true mean amount of nitrogen in distributor B's fertilizer. Our null hypothesis is:
H0: μA - μB ≤ 0
The alternative hypothesis is:
Ha: μA - μB > 0
We will use a one-tailed test with a significance level of 0.05. Since we have two independent samples with sample sizes of 4 each, we will use a pooled t-test with the following formula:
t = ([tex]\bar{X1}[/tex] - [tex]\bar{X2}[/tex] - D) / (sP * √(2/n))
where [tex]\bar{X1}[/tex] and [tex]\bar{X2}[/tex] are the sample means, D is the hypothesized difference between the population means, sP is the pooled standard deviation, and n is the sample size.
To calculate the pooled standard deviation, we can use the following formula:
sP = √(((n1-1)*s1² + (n2-1)*s2²) / (n1+n2-2))
where n1 and n2 are the sample sizes, and s1 and s2 are the sample standard deviations.
Plugging in the given values, we get:
[tex]\bar{X1}[/tex] = 21, [tex]\bar{X2}[/tex] = 16
s1 = s2 = 1.5 (since we are assuming the population standard deviation is the same for both distributors)
n1 = n2 = 4
D = 0 (since the null hypothesis is that there is no difference in the means)
sP = √(((4-1)*1.5² + (4-1)*1.5²) / (4+4-2)) = 1.5
Using these values, we get:
t = (21 - 16 - 0) / (1.5 * √(2/4)) = 6.93
Looking at a t-distribution table with 6 degrees of freedom (4+4-2), we find that the critical value for a one-tailed test at a significance level of 0.05 is approximately 1.943. Since our calculated t-value of 6.93 is greater than the critical value, we reject the null hypothesis and conclude that there is strong evidence that the mean amount of nitrogen in distributor A's fertilizer is significantly greater than the mean amount of nitrogen in distributor B's fertilizer.
