f(x) = x3 + 3x² - 4x

Answer:

y-intercept: (0, 1)

x-intercept: (1, 0)

an x-intercept is when a line crosses the x-axis, and a y-intercept is when a line crosses the y axis.

The y-intercept of the line is 0.5, because it is the point that divides the square into two equal areas with a line of slope 5.

The line with slope 5 splits the square with vertices at (0,0), (1,0), (1,1), and (0,1) into two regions with equal area. To find the y-intercept of this line, we need to solve for the point where the line intersects the y-axis. To do this, we can set the x-value of the line equal to 0, since the y-axis is the vertical line where x=0. This gives us the equation 5y = 0. We can then solve this equation to find that the y-intercept of the line is 0.5. This means that the line with slope 5 intersects the y-axis at (0, 0.5). This is the point that divides the square into two regions with equal area.

Answer: 163.2°

Step-by-step explanation:

We need approximately 10 deposits to reach a balance of $31,300 four years after the last deposit which is compounded semi-annually.

To solve this problem, we can use the formula for the future value of an annuity:

\(FV = P * ((1 + r)^n - 1) / r\)

Where:

FV is the future value of the annuity

P is the periodic payment or deposit amount

r is the interest rate per period

n is the number of periods

In this case, the deposit amount is $726.56, the interest rate is 6.45% compounded semi-annually, and the future value is $31,300. We need to find the number of deposits (n).

We can rearrange the formula and solve for n:

n = log((FV * r) / (P * r + FV)) / log(1 + r)

Substituting the given values:

n = log((31,300 * 0.03225) / (726.56 * 0.03225 + 31,300)) / log(1 + 0.03225)

Using a calculator or software, we find that n ≈ 9.989.

Therefore, we need approximately 10 deposits to reach a balance of $31,300 four years after the last deposit.

Step-by-step explanation:

The monthly payment required to amortize a loan of $40,000 over 15 years, with an interest rate of 6% per year, and monthly compounding, is approximately $331.13.

To calculate the monthly payment, we can use the formula for the amortization of a loan, which is:

Monthly Payment = P * (r * (1 + r)^n) / ((1 + r)^n - 1),

where P is the principal amount (loan amount), r is the monthly interest rate, and n is the total number of payments.

Given:

Principal amount (P) = $40,000,

Annual interest rate = 6%,

Number of years (n) = 15.

First, we need to convert the annual interest rate to a monthly interest rate. Since interest is compounded monthly, the monthly interest rate (r) is calculated by dividing the annual interest rate by 12 and converting it to a decimal:

Monthly interest rate (r) = 6% / 12 / 100 = 0.005.

Next, we calculate the total number of payments (n) by multiplying the number of years by 12 (since there are 12 months in a year):

Total number of payments (n) = 15 years * 12 months/year = 180.

Now we can plug these values into the formula to calculate the monthly payment:

Monthly Payment = $40,000 * (0.005 * (1 + 0.005)^180) / ((1 + 0.005)^180 - 1).

Using a calculator or spreadsheet, we find that the monthly payment is approximately $331.13.

Therefore, the monthly payment required to amortize the loan of $40,000 over 15 years, with a 6% annual interest rate and monthly compounding, is approximately $331.13.

Mean is nothing but the average of the given set of values. It denotes the equal distribution of values for a given data

set.  The mean, median and mode are the three commonly used measures of central tendency.

To calculate the mean, we need to add the total values given in a datasheet and divide the sum by the total number of

The mean, μ, of the sampling distribution of p can be found using the formula

μ = p,

where p is the proportion of adults in the entire population who support the increase.

In this case, 40% of all adults in Ohio support the increase, so p = 0.40.

Answer:

To create a box plot, we need to find the minimum, maximum, median, and quartiles of the data.

The minimum value is 2, and the maximum value is 13.

To find the median, we need to order the data from smallest to largest:

2, 5, 6, 6, 7, 7, 8, 8, 9, 11, 13

The middle value is the median. Since there are 11 data points, the median is the average of the 6th and 7th values, which is:

median = (7 + 8)/2 = 7.5

To find the quartiles, we need to find the median of the lower half of the data and the median of the upper half of the data.

Lower half:

2, 5, 6, 6, 7

Median of the lower half = 6

Upper half:

8, 8, 9, 11, 13

Median of the upper half = 9

So, the quartiles are 6 and 9.

One possible value of ∠U is 80° (to the nearest degree).

A triangle is a three-sided polygon with three vertices. The triangle's internal angle, which is 180 degrees, is constructed.

To find the possible values of ∠U, we can use the Law of Cosines:

c² = a² + b² - 2ab cos(C)

Where c is the side opposite the angle we want to find (∠U), a and b are the other two sides, and C is the angle opposite side c.

In this case, we want to find ∠U, so we'll use side u as c and sides t and s (which we don't know yet) as a and b, respectively:

u² = t² + s² - 2ts cos(U)

Substituting the given values, we get:

340² = 620² + s² - 2(620)(s)cos(U)

Simplifying:

115600 = 384400 + s² - 1240s cos(U)

Subtracting 384400 and rearranging:

s² - 1240s cos(U) + 268800 = 0

Now we can use the quadratic formula to solve for s:

s = [1240 cos(U) ± √(1240² cos²(U) - 4(1)(268800))]/(2)

Simplifying under the square root:

s = [1240 cos(U) ± √(1537600 cos²(U) - 1075200)]/(2)

s = [1240 cos(U) ± √(409600 cos²(U) + 1742400)]/(2)

s = [620 cos(U) ± √(102400 cos²(U) + 435600)]

Since s must be positive, we can discard the negative solution, and we have:

s = 620 cos(U) + √(102400 cos²(U) + 435600)

Now we can use the fact that the sum of angles in a triangle is 180° to find ∠U:

∠U = 180° - ∠T - ∠S

Since we know ∠T = 110°, we just need to find ∠S. We can use the Law of Sines to do this:

sin(S)/s = sin(T)/t

sin(S) = (s/t)sin(T)

Substituting the values we know:

sin(S) = (620 cos(U) + √(102400 cos²(U) + 435600))/620 * sin(110°)

sin(S) ≈ (1.481 cos(U) + 2.225)/6.959

Now we can use a calculator to find the arcsin of both sides to get ∠S:

∠S ≈ arcsin((1.481 cos(U) + 2.225)/6.959)

Finally, we can substitute the values we found for ∠S and ∠T into the equation we found earlier for ∠U:

∠U = 180° - 110° - arcsin((1.481 cos(U) + 2.225)/6.959)

Simplifying:

∠U = 70° - arcsin((1.481 cos(U) + 2.225)/6.959)

Now we can use trial and error or a graphing calculator to find the values of ∠U that satisfy this equation. One possible solution is:

∠U ≈ 80°

Therefore, one possible value of ∠U is 80° (to the nearest degree).

Given For all x, 10 cos (2 x) ≤ f(x) ≤ 7 x^{2}+10

To Find lim_{x → 0} f(x)

Let us solve this question step by step.

Let us assume that g(x) = 10 cos (2 x) and h(x) = 7 x^{2}+10

So, g(0) = 10 cos (2 × 0) = 10and h(0) = 7 × 0^{2}+10 = 10

As for all x, 10 cos (2 x) ≤ f(x) ≤ 7 x^{2}+10

On substituting x = 0 in the above inequality, we get10 ≤ f(0) ≤ 10=> f(0) = 10

We know that,if lim_{x → 0} g(x) = L, then lim_{x → 0} (-g(x)) = -L

Also,if g(x) ≤ h(x) for all x in an interval containing 0, and if lim_{x → 0} g(x) = L, then lim_{x → 0} h(x) = L.So, -10 ≤ -g(x) ≤ -f(x) ≤ -h(x) ≤ 10So,lim_{x → 0} -g(x) = -10 and lim_{x → 0} -h(x) = -10

Applying squeeze theorem,lim_{x → 0} -f(x) = -10and lim_{x → 0} f(x) = 10 Therefore,lim_{x → 0} f(x) = 10Hence, the solution is 10.
