Find where (if anywhere) the function y=w 3
+w 2
−5w has a horizontal tangent line. (Extra Credit) Draw me.
The function y = w3 + w2 - 5w is a polynomial function of degree 3.
A horizontal tangent line occurs when the derivative of the function is zero.
Therefore, let's find the derivative of the given function:
dy/dw = 3w2 + 2w - 5
Now, let's set dy/dw equal to zero and solve for w:
3w2 + 2w - 5 = 03w2 + 2w = 5w(3w + 2) = 5w = 0 or w = -2/3 or w = 5/3
Thus, the function has horizontal tangent lines at w = -2/3 and w = 5/3.
To verify this, we can check the second derivative of the function:
d²y/dw² = 6w + 2At w = -2/3, d²y/dw² = 6(-2/3) + 2 = -2 < 0,
so the function has a local maximum at this point. At
w = 5/3, d²y/dw² = 6(5/3) + 2 = 12 > 0,
so the function has a local minimum at this point.
Extra Credit: To draw the function, we can first plot the horizontal tangent lines at
w = -2/3 and w = 5/3.
Next, we can plot the function for values of w near these points and connect them smoothly to create a graph.
The graph would be a curve with a local maximum at w = -2/3 and a local minimum at w = 5/3.

work out m and c for the line: 5x-3y+4=0
Answer:
\(m = \frac{5}{3}\)
\(b = \frac{4}{3}\)
Step-by-step explanation:
The question requires you to rearrange the equation into the form:
y = mx + c
Which is the straight line equation, meaning rearrange for y:
Add 3y to both sides of the equation:
5x - 3y + 4 = 0
5x - 3y + 4 + 3y = 0 + 3y
5x + 4 = 3y
Divide both sides of the equation to isolate y:
\(\frac{5x}{3} + \frac{4}{3} = \frac{3y}{3}\)
\(y = \frac{5}{3}x + \frac{4}{3}\)
This means that \(m = \frac{5}{3}\) and \(b = \frac{4}{3}\).
Hope this helps!
Answer:
m = 5/3 and c = 4/3.
Step-by-step explanation:
5x - 3y + 4 = 0
-3y = -5x - 4
y = (-5/-3)x - 4/-3
y = 5/3 x + 4/3
y = mx + c
So m = 5/3 and c = 4/3
Suppose you want to save $5000 to put towards remodeling your house in 18 months. You found a bank whose interest rate for savings accounts is 4.5% compounded monthly, but you are unsure of how much to invest to have $5000 saved in 18 months.
Using the compound interest formula, how much should you invest in order to have $5000 saved in 18 months?
The required money to be invested in order to save $5000 is $4677.26.
What is compound interest?The compound interest is a form of interest where the rate of interest is applied on the amount obtained after every interval of time.
The principal for each interval is the sum of interest And the principal for the previous interval.
Suppose the amount to be invested be P.
The rate of interest for monthly compounding is given as 4.5/12 = 0.375%.
Time is given as 18 months.
This implies number of time period is 18.
Plug n = 18, r = 0.375% and A = 5000 in A = P(1 + r/100)ⁿ as,
⇒ 5000 = P(1 + 0.375/100)¹⁸
⇒ P = 4677.26
Hence, the amount of money that should be invested is obtained as $4677.26.

Find the values of x for which the function is continuous.

x^2 + 7 if x ≥ 0
a.x ≠ 0
b.x ≥ 0
c.x ≥ root square 7
d.all real numbers
e.x ≠ 7
It looks like the given function is
\(f(x) = \begin{cases}-3x + 7 & \text{if }x < 0 \\ x^2+7 & \text{if }x \ge0\end{cases}\)
The two pieces of f(x) are continuous since they are polynomials, so we only need to worry about the point at which they meet, x = 0. f(x) is continuous there if
\(\displaystyle \lim_{x\to0^-} f(x) = \lim_{x\to0^+} f(x) = f(0) = 7\)
To the left of x = 0, we have x < 0, so f(x) = -3x + 7 :
\(\displaystyle \lim_{x\to0^-} f(x) = \lim_{x\to0} (-3x + 7) = 7\)
To the right of x = 0, we have x > 0 and f(x) = x² + 7 :
\(\displaystyle \lim_{x\to0^+} f(x) = \lim_{x\to0} (x^2 + 7) = 7\)
So f(x) is continuous at x = 0, and hence continuous for all real numbers.

a baseball diamond is a square with side ft. a batter hits the ball and runs toward first base with a speed of . at what rate is his distance from second base decreasing when he is halfway to first base? at what rate is his distance from third base increasing at the same moment?
When the batter is halfway to first base in a baseball diamond, the rate at which his distance from second base is decreasing is 0 ft/s, while the rate at which his distance from third base is increasing is √2 ft/s.
To analyze the situation, we can consider the geometry of the baseball diamond. Since the diamond is a square, each side has a length of ft.
When the batter is halfway to first base, he forms a right triangle with second base and third base. The hypotenuse of this triangle represents the distance from second base to third base, which is √2 times the length of one side of the square.
At this moment, the batter is moving directly towards first base, which is perpendicular to the line connecting second and third base. Therefore, the rate at which his distance from second base is decreasing is 0 ft/s since he is not changing his distance from second base.
On the other hand, the rate at which his distance from third base is increasing can be calculated. Since the hypotenuse (distance from second base to third base) is √2 times the length of one side, we can differentiate with respect to time to find the rate of change. Thus, the rate at which his distance from third base is increasing is √2 ft/s.
Therefore, when the batter is halfway to first base in a baseball diamond, his distance from second base is not changing, while his distance from third base is increasing at a rate of √2 ft/s.

Edmond doubled the width of the crate. How do the perimeter and the area of the floor of the new crate compare to those of the original crate? Original:length = 1.2 metres width = 0.8 metres
Answer:
The area would be doubled also
The perimeter will be increased in a factor of 1.4
Step-by-step explanation:
Originally the area of new crate = L * B = 1.2 * 0.8 = 0.96 m^2
perimeter is 2(L+ B) = 2(1.2 + 0.8) = 4 m
Now let’s double the width , it becomes 0.8 * 2 = 1.6 m
Area would be 1.6 * 1.2 = 1.92 m^2 which is two times the previous area
The increased perimeter will be 2(1.6 + 1.2) = 5.6 m
This is an increase in factor of 1.4
researcher wants to support the claim that wearing earplugs will reduce the chance of hearing loss. the researcher conducted the appropriate 2 population t-test with a treatment and control group and got a p-value less than a significance level of 5%. the researcher then claimed with 95% confidence that wearing earplugs will reduce the chance of hearing loss. is this reasoning valid?
Two- tailed t- test, determined the 97.5% confidence level for p-value less than a significance level of 5%. So, researcher claims with 95% confidence that wearing earplugs will reduce the chance of hearing loss is also correct.
We have specify that a researcher wants to support the claim that wearing earplugs will reduce the chance of hearing loss.
Significance level= 5% = 0.05
P-value< 0.05
Now, the p-value for a two tailed test is computed by = 2× Area of the lower tail on one side. Here, P-value< 0.05, therefore Area of the lower tail on one side < 0.05 / 2
=> p-value for a one tailed test < 0.025
that represents the 97.5% confidence level. So, the researcher can actually claim here even at 97.5% confidence level that wearing earplugs will reduce the chance of hearing loss but even concluding at any confidence level less than 97.5% would be correct. Therefore the researcher is not incorrect in concluding here the given concluion at 95% confidence level.

Student borrowers now have more options to choose from when selecting repayment plans. The standard plan repays the loan in up to 10 years with equal monthly payments. The extended plan allows up to 25 years to repay the loan. Suppose that a student borrows $55,000 at 4.66% compounded monthly.
a) Find the monthly payment and total interest paid under the standard plan over 10 years.
b) Find the monthly payment and total interest paid under the extended plan over 25 years.
a) Monthly payment under the standard plan over 10 years:
It is given that, P = $55,000r = 4.66% per annum compounded monthly
n = 10 × 12 = 120 months
Let the monthly payment be A. Using the formula for monthly payments of a loan,
we have: P = A [{(1 + r)n - 1} / r]A = P / [{(1 + r)n - 1} / r]A = $55,000 / [{(1 + 0.0466 / 12)¹²⁰ - 1} / (0.0466 / 12)]
A = $580.29
Therefore, the monthly payment under the standard plan over 10 years is $580.29.
Total interest paid under the standard plan over 10 years:
Total interest paid = Total amount paid - Loan amount= (A × n) - P
= ($580.29 × 120) - $55,000
= $69,634.80 - $55,000
= $14,634.80
Therefore, the total interest paid under the standard plan over 10 years is $14,634.80.
b) Monthly payment under the extended plan over 25 years:
It is given that, P = $55,000r = 4.66% per annum compounded monthly
n = 25 × 12 = 300 months
Let the monthly payment be B. Using the formula for monthly payments of a loan,
we have: P = B [{(1 + r)n - 1} / r]B = P / [{(1 + r)n - 1} / r]B = $55,000 / [{(1 + 0.0466 / 12)³⁰⁰ - 1} / (0.0466 / 12)]B = $319.36
Therefore, the monthly payment under the extended plan over 25 years is $319.36.
Total interest paid under the extended plan over 25 years:
Total interest paid = Total amount paid - Loan amount= (B × n) - P= ($319.36 × 300) - $55,000
= $95,808.00 - $55,000= $40,808.00
Therefore, the total interest paid under the extended plan over 25 years is $40,808.00.

The formula for finding a midpoint is ((x1 + x2) / 2, (y1 + y2) / 2)
However, in this problem, we're already given the midpoint. We're trying to find an endpoint. So, the equation changes into:
((x + 9) / 2 = 4, (y + 0) / 2 = -2)
For the x and y coordinates, multiply both sides by 2
(x + 9 = 8, y = -4)
(x = -1, y = -4)
Rewrite as coordinates.

The number of points is simply 5 times this random variable, and E(C*Y) = C*E(Y), where C is a constant and Y is a random variable, according to expected value principles. As a result, E(X) = 5*2 = 10.
What is probability?The field of mathematics concerned with probability is known as probability theory. Although there are various distinct interpretations of probability, probability theory approaches the idea rigorously mathematically by articulating it through a set of axioms. A probability is a number that represents the possibility or chance that a specific event will occur. Probabilities can be stated as proportions ranging from 0 to 1, as well as percentages ranging from 0% to 100%.
Here,
The number of dice that are showing an even number is a binomial random variable with n = 4, and p = 1/2 (because half the faces on the die are even and half are odd).
The expected value of this random variable is n*p = 4*1/2 = 2.
The number of points is simply 5 times this random variable, and by the rules of expected value, E(C*Y) = C*E(Y), where C is a constant and Y is a random variable. Thus E(X) = 5*2 = 10.

Kathy is financing $218,675 to purchase a house. she obtained a 30/10 balloon mortgage at 3.35%. what will her balloon payment be?
With a principal balance of $218,675 and an interest rate of 3.35%, Kathy's balloon payment on her 30/10 balloon mortgage will be around $176,773.
A balloon mortgage is a type of loan with fixed monthly payments for a set amount of time, in this case 30 years, but a sizable final payment due at the end of the term, in this case after 10 years, known as the balloon payment.
We must figure out the remaining principal balance after the original 30-year period in order to calculate the balloon payment. To determine this amount, we can utilise an amortisation schedule.
Using the method for a fixed-rate mortgage, we can get the monthly payment using the loan amount of $218,675, the interest rate of 3.35%, and the period of 30 years. The equation is:
\(M = P * (r * (1 + r)^n) / ((1 + r)^n - 1)\)
where n is the total number of payments (30 years multiplied by 12 months), M is the monthly payment, P is the loan balance, r is the monthly interest rate (3.35% divided by 12), and P is the loan amount.
By deducting the principal payments made over the first 10 years from the initial loan amount after calculating the monthly payment, we can calculate the residual principal balance after the first 10 years. The balloon payment will be made on this outstanding balance.
The result of the monthly payment calculation is $963.
Kathy will have paid 120 payments (120 divided by 10) after 10 years. Using the amortisation plan, we determine that there will be roughly $41,902 left on the principle balance after 10 years. This sum is the completed balloon payment.
