To find the critical numbers of h(x) = sin^2(x) + cos(x) in 0 < x < 2π steps are first to find the derivative h'(x), set h'(x) equal to zero and solve for x and check if solutions are within the given interval. The critical numbers are x = π, π/3, and 5π/3.
To find the critical numbers of the function h(x) = sin^2(x) + cos(x) in the interval 0 < x < 2π, we will follow these steps:
Find the derivative of the function, Set the derivative equal to zero and solve for x, Set h'(x) equal to zero and solve for x, Check if the solutions are within the given interval.
1: Differentiate h(x) with respect to x.
h'(x) = d(sin^2(x) + cos(x))/dx
Using chain rule, we get:
h'(x) = 2sin(x)cos(x) - sin(x)
2: Set h'(x) equal to zero and solve for x.
0 = 2sin(x)cos(x) - sin(x)
Factor out sin(x):
0 = sin(x)(2cos(x) - 1)
So, either sin(x) = 0 or 2cos(x) - 1 = 0.
3: Solve for x and check if the solutions are within the interval 0 < x < 2π.
For sin(x) = 0, x = π (since 0 < π < 2π).
For 2cos(x) - 1 = 0, cos(x) = 1/2.
x = π/3 and 5π/3 (since 0 < π/3 < 2π and 0 < 5π/3 < 2π).
Therefore, the critical numbers of the function h(x) = sin^2(x) + cos(x) in the interval 0 < x < 2π are x = π, π/3, and 5π/3.

You deposit $2000 earned at a summer job in an account that pays 4. 2% simple interest. What is the balance in the account in 3 years? Estimate to the nearest whole number
A deposit of $2000 earning 4.2% simple interest for 3 years will have a balance of $2252. The estimated balance rounded to the nearest whole number is $2252.
To calculate the balance in the account after 3 years, we can use the formula
balance = principal x (1 + interest rate x time)
Plugging in the values, we get
balance = 2000 x (1 + 0.042 x 3)
balance = 2000 x (1 + 0.126)
balance = 2000 x 1.126
balance = 2252
Therefore, the balance in the account after 3 years is $2252.
As for the estimate, since the interest is simple, we can approximate it by multiplying the interest rate by the number of years and adding it to the principal. So, the estimate would be
estimate = principal x (1 + interest rate x time)
estimate = 2000 x (1 + 0.042 x 3)
estimate = 2000 x (1 + 0.126)
estimate = 2000 x 1.126
estimate = 2252
Rounding to the nearest whole number, the estimate is also $2252.

What is the value of k?
k = -4
k = 4
k = -1/4
Answer:
k = 1
Step-by-step explanation:
We can use the table for g(x) = f(kx) to find the value of k.
Notice that when x = -2, we have g(-2) = f(k(-2)) = f(-2k) = 64. Similarly, when x = 2, we have g(2) = f(k(2)) = f(2k) = 64.
Using the fact that f(x) is a quadratic function, we can see that its axis of symmetry passes through the vertex at (0, 0), which means that the x-coordinate of the vertex is 0. This tells us that the coefficient of the x term in f(x) is 0, so the function can be written as f(x) = ax^2 + bx + c, where a is not equal to 0.
Using the points (−2,4), (−1,1), (0,0), (1,1), and (2,4), we can write a system of equations to solve for a, b, and c:
a(-2)^2 + b(-2) + c = 4
a(-1)^2 + b(-1) + c = 1
a(0)^2 + b(0) + c = 0
a(1)^2 + b(1) + c = 1
a(2)^2 + b(2) + c = 4
Simplifying and rearranging, we get:
4a - 2b + c = 4
a - b + c = 1
c = 0
a + b + c = 1
4a + 2b + c = 4
Substituting c = 0 into the system, we get:
4a - 2b = 4
a - b = 1
a + b = 1
4a + 2b = 4
Solving this system of equations, we get a = 1, b = -1, and c = 0.
Substituting these values into g(x) = f(kx), we get:
g(x) = f(kx) = x^2 - x
Substituting the values from the table into this equation, we get:
g(-2) = 4 = (-2)^2 - (-2) = 4k
g(2) = 4 = (2)^2 - (2) = 4k
Solving for k, we get k = 1 or k = -1/4.
However, we need to check which value of k satisfies all the points in between -2 and 2, so we can check g(-1) = 1 = (-1)^2 - (-1) = k, and g(1) = 1 = (1)^2 - (1) = k.
Thus, the value of k that satisfies all the points is k = 1, and therefore the answer is:
k = 1
We can use the information given to find the value of k.
Since the vertex of the quadratic function f(x) is at (0,0), we know that the equation for f(x) is in the form of f(x) = ax^2 for some constant a.
Using the point (-2, 4) on the graph of f(x), we can set up the equation 4 = 4a, which gives us a = 1.
So, the equation for f(x) is f(x) = x^2.
Now, we can use the table for g(x) = f(kx) to find the value of k.
When x = -2, we have g(-2) = f(k(-2)) = f(-2k) = 4k^2.
Similarly, when x = 2, we have g(2) = f(k(2)) = f(2k) = 4k^2.
We also know that g(0) = f(k(0)) = f(0) = 0, and g(-1) = f(k(-1)) = f(-k) = k^2 and g(1) = f(k(1)) = f(k) = k^2.
Using the values from the table, we can set up the following system of equations:
4k^2 = 64
k^2 = 16
0 = 0
k^2 = 16
The only solution that works for all of these equations is k = 4 or k = -4.
Therefore, the value of k is either k = 4 or k = -4.

The angles that belongs to the right angles category are:
∠KER∠AREWhat makes a right angle in a circle?KER must be a right angle because it is an angle formed between a tangent (KE) and a radius (AK) at the point of tangency (K). By the Tangent-Secant Theorem, it follows that the measure of the intercepted arc KR is equal to the measure of the angle ∠KER plus 90 degrees. Since KR is a diameter (and therefore a semicircle), its measure is 180 degrees. Therefore, ∠KER + 90 = 180, which implies that ∠KER = 90 degrees.
∠ARE must be a right angle because it is an inscribed angle that intercepts the diameter KR. By the Inscribed Angle Theorem, the measure of an inscribed angle is half the measure of its intercepted arc. Since KR is a diameter, the intercepted arc is the entire circle, which has a measure of 360 degrees. Therefore, ∠ARE = 360/2 = 180 degrees. Moreover, a diameter and a chord that contains the diameter must form a right angle at the point where they meet (in this case, point A). Hence, ∠ARE is a right angle.

The base and all three faces of a triangle pyramid are equilateral triangles with side lengths of 3ft. the height of each triangle is 2.6ft. what are the lateral area and the total surface area of the triangular pyramid?
The lateral area of the triangular pyramid is 11.7 sq ft and the total surface area is 15.6 sq ft.
To find the lateral area and total surface area of the triangular pyramid with base and faces as equilateral triangles, we can follow these steps:
1: Find the area of one equilateral triangle.
To find the area of an equilateral triangle with side length 3 ft and height 2.6 ft, we can use the formula:
Area = (1/2) × base × height
Area = (1/2) × 3 × 2.6 = 3.9 sq ft
2: Calculate the lateral area.
Since the pyramid has three equilateral triangles as faces, we can multiply the area of one triangle by 3 to find the lateral area:
Lateral Area = 3 × 3.9 = 11.7 sq ft
3: Calculate the total surface area.
The total surface area includes both the lateral area and the base area. Since the base is also an equilateral triangle with the same dimensions, we can simply add the area of the base to the lateral area to find the total surface area:
Total Surface Area = Lateral Area + Base Area = 11.7 + 3.9 = 15.6 sq ft

An investor purchases 500 shares of Exxon-mobil stock at $98. 93 per share. His broker charges 2% of the cost of the stock. What is the cost of the stock?
The cost of the stock, including the broker's fee, is $50,454.30.
How to find the total cost of stock?The cost of the stock can be found by multiplying the number of shares purchased by the price per share. In this case, the investor purchased 500 shares of Exxon-mobil stock at $98.93 per share, so the cost of the stock can be calculated as follows:
Cost of stock = Number of shares × Price per share
Cost of stock = 500 × $98.93
Cost of stock = $49,465
However, the broker charges 2% of the cost of the stock, which is an additional fee that needs to be added to the total cost. To find the broker's fee, we can simply multiply the cost of the stock by 2%:
Broker's fee = 2% × Cost of stock
Broker's fee = 2% × $49,465
Broker's fee = $989.30
Therefore, the total cost of the stock, including the broker's fee, is:
Total cost of stock = Cost of stock + Broker's fee
Total cost of stock = $49,465 + $989.30
Total cost of stock = $50,454.30

The correct answer for an angle coterminal to -497° within the interval 0°≤θ≤360° is 223°.
What are Coterminal angles?
Coterminal angles are angles that share the same initial and terminal sides when drawn in the standard position (starting from the positive x-axis) on the coordinate plane. In other words, coterminal angles are angles that differ by an integer multiple of 360° or 2π radians.
To find an angle coterminal to within the interval use the fact that to add or subtract a multiple of to an angle does not change its position on the unit circle.
To make the angle positive, add 360° repeatedly until an angle within the desired interval is obtained:

Find f'(4) for f(x) = ln (2x^3"). Answer as an exact fraction or round to at least 2 decimal places.
To find f'(4) for the function f(x) = ln(2x^3), we first need to find the derivative f'(x) using the chain rule.
The chain rule states that the derivative of a composite function is the derivative of the outer function times the derivative of the inner function.
For f(x) = ln(2x^3), the outer function is ln(u) and the inner function is u = 2x^3.
The derivative of the outer function, ln(u), is 1/u.
The derivative of the inner function, 2x^3, is 6x^2 (using the power rule).
Now, apply the chain rule: f'(x) = (1/u) * 6x^2 = (1/(2x^3)) * 6x^2.
Simplify f'(x): f'(x) = 6x^2 / (2x^3) = 3/x.
Now, find f'(4): f'(4) = 3/4.
So, f'(4) for f(x) = ln(2x^3) is 3/4 or 0.75 when rounded to 2 decimal places.

With the given pay increase Daniel will earn a total of $185,141.90 in 4 years .
To find out how much Daniel will earn in 4 years with a starting salary of $42,000 and a 6.5% pay increase every year, follow these steps:
1. Calculate the annual salary for each year by applying the percentage increase.
2. Sum up the salaries for all 4 years.
Step 1: Calculate the annual salary for each year
Year 1: $42,000
Year 2: $42,000 * (1 + 6.5%) = $42,000 * 1.065 = $44,730
Year 3: $44,730 * (1 + 6.5%) = $44,730 * 1.065 = $47,656.95
Year 4: $47,656.95 * (1 + 6.5%) = $47,656.95 * 1.065 = $50,754.95
Step 2: Sum up the salaries for all 4 years
Total earnings = $42,000 + $44,730 + $47,656.95 + $50,754.95 = $185,141.90
Daniel will earn a total of $185,141.90 in 4 years with the given pay increase.

Find an angle in each quadrant with a common reference angle with 306°, from 0°≤θ<360°
The angle in each quadrant with a common reference angle with 306° are
Quadrant 1 is 126°Quadrant 2 is 54°Quadrant 3 is 306°Quadrant 4 is 234°To find angles in each quadrant with a common reference angle with 306°, we first need to determine the reference angle for 306°.
Reference angle is the acute angle between the terminal side of an angle and the x-axis. We can find the reference angle for any angle θ by subtracting the nearest multiple of 180° from θ and taking the absolute value of the result. In this case:
|306° - 180°| = 126°
So, the reference angle for 306° is 126°.
Now, we can find an angle in each quadrant with a common reference angle of 126°:
1st quadrant: The angle with a reference angle of 126° in the 1st quadrant is simply 126°.
2nd quadrant: To find the angle with a reference angle of 126° in the 2nd quadrant, we need to subtract the reference angle from 180° (since all angles in the 2nd quadrant are between 90° and 180°).
180° - 126° = 54°
So, an angle with a reference angle of 126° in the 2nd quadrant is 54°.
3rd quadrant: To find the angle with a reference angle of 126° in the 3rd quadrant, we need to subtract the reference angle from 180° and then add 180° (since all angles in the 3rd quadrant are between 180° and 270°).
180° + 126° = 306°
So, an angle with a reference angle of 126° in the 3rd quadrant is 306°.
4th quadrant: To find the angle with a reference angle of 126° in the 4th quadrant, we need to subtract the reference angle from 360° (since all angles in the 4th quadrant are between 270° and 360°).
360° - 126° = 234°
So, an angle with a reference angle of 126° in the 4th quadrant is 234°.

Answer:
6cm
Step-by-step explanation:
all the sides of a square are identical so we can assume the missing side as x
since all four sides are the same and the perimeter is the sum of all sides, we can write
x+x+x+x=24cm
4x=24cm
x=24/4
x=6cm
What is the mean absolute deviation of 10 10 9 8 10 5 6 4 8 4
The mean absolute deviation of the given data set is approximately 2.16.
To find the mean absolute deviation (MAD), we first need to calculate the mean of the data set:
Mean = (10 + 10 + 9 + 8 + 10 + 5 + 6 + 4 + 8 + 4) / 10 = 7.4
Next, we calculate the absolute deviation of each data point from the mean:
|10 - 7.4| = 2.6
|10 - 7.4| = 2.6
|9 - 7.4| = 1.6
|8 - 7.4| = 0.6
|10 - 7.4| = 2.6
|5 - 7.4| = 2.4
|6 - 7.4| = 1.4
|4 - 7.4| = 3.4
|8 - 7.4| = 0.6
|4 - 7.4| = 3.4
Then, we find the average of these absolute deviations:
MAD = (2.6 + 2.6 + 1.6 + 0.6 + 2.6 + 2.4 + 1.4 + 3.4 + 0.6 + 3.4) / 10 ≈ 2.16
Therefore, the mean absolute deviation of the given data set is approximately 2.16.

Ruby and Emma can assemble one gift basket in 0.1818 minutes, together. They will finish the 54th basket at 7:27 PM.
To solve the problem, we first need to find how many gift baskets Ruby and Emma can assemble in one minute.
Ruby can assemble 2/22 = 1/11 gift basket in one minute.
Emma can assemble 4/44 = 1/11 gift basket in one minute.
Together, they can assemble 1/11 + 1/11 = 2/11 = 0.1818 (rounded to four decimal places) gift baskets in one minute.
To assemble the 54th gift basket, they need to assemble 53 gift baskets before that.
53 gift baskets / 0.1818 gift baskets per minute = 291.8181 minutes
Since they start at 1:00 p.m. and Emma starts 15 minutes later, they will finish 291.8181 minutes after 1:15 p.m., which is approximately 7:27 p.m.
