The value of angle c is 86.

We have,

a = 68

b = 26

We are assuming that in the triangle there are three angles:

a, b, and c

Now,

The sum of the angles in the triangle is 180.

So,

a + b + c = 180

68 + 26 + c = 180

94 + c = 180

c = 180 - 94

c = 86

Thus,

The value of angle c is 86.

Given that angle a = 68° and angle b = 26° in the triangle.

Find the angle c.

The dimensions of the rectangle with an area of 1,000 m² and the smallest possible perimeter are: m (smaller value) = 25 m (larger value) = 40

To find the dimensions of a rectangle with area 1,000 m2 and the smallest possible perimeter, we need to use the formula for the perimeter of a rectangle, which is P = 2(l + w), where l and w are the length and width of the rectangle, respectively.

Since the area of the rectangle is given as 1,000 m2, we can express the length in terms of the width as l = 1000/w. Substituting this into the formula for perimeter, we get: P = 2(1000/w + w).

To find the smallest possible perimeter, we need to minimize this expression by taking its derivative with respect to w and setting it equal to zero: dP/dw = -2000/w^2 + 2 = 0 Solving for w, we get: w = sqrt(1000) ≈ 31.62 m.

Substituting this value back into the expression for the perimeter, we get: P = 2(1000/sqrt(1000) + sqrt(1000)) ≈ 126.5 m.

Therefore, the dimensions of the rectangle with the smallest possible perimeter and area 1,000 m2 are: m (smaller value) = sqrt(1000) ≈ 31.62 m m (larger value) = 1000/sqrt(1000) ≈ 31.62 m Note that both values are the same, as expected from the problem statement.

To minimize the perimeter of a rectangle with a given area, the rectangle should be as close to a square as possible. The area of a rectangle is given by the formula A = length × width, where A = 1,000 m². Let's find the square root of the area: √1,000 ≈ 31.62. Since the dimensions must be whole numbers, we'll look for the nearest factors of 1,000. The closest factors are 25 and 40.

Answer:

A

Step-by-step explanation:

Continuous data is a continuous scale that covers a range of values without gaps, interruptions, or jumps.

The change in angular momentum of the bolt is 11.25 kg m²/s.

Angular momentum is a measure of an object's tendency to keep rotating. It is calculated as the product of the object's moment of inertia and its angular velocity. The change in angular momentum is given by the torque applied to the object over a certain time interval. In this case, 45 Nm of torque is applied to a large bolt in 0.25s, and we need to find the change in angular momentum of the bolt.

To find the change in angular momentum, we need to first calculate the moment of inertia of the bolt. This depends on the shape and size of the bolt. Once we have the moment of inertia, we can use the formula:

Change in angular momentum = torque x time interval

Substituting the given values, we get:

Change in angular momentum = 45 Nm x 0.25 s = 11.25 Nms

Therefore, the change in angular momentum of the bolt is 11.25 Nms. This means that the bolt's tendency to rotate has increased by this amount due to the torque applied to it.

According to unitary method, Marques made 2 three-point shots and 6 free throws in the game.

Let's say Marques made x three-point shots and y free throws. Since a three-point shot is worth three points and a free throw is worth one point, we can write two equations to represent the total number of points scored and the total number of shots made:

3x + y = 12 (equation 1)

x + y = 8 (equation 2)

We can now use the unitary method to solve for x and y. We want to find the value of one three-point shot, so we can rearrange equation 1 to get:

3x = 12 - y

x = (12 - y) / 3

Similarly, we want to find the value of one free throw, so we can rearrange equation 2 to get:

y = 8 - x

We can substitute the second equation into the first equation to get:

3x = 12 - (8 - x)

3x = 4 + x

2x = 4

x = 2

Now that we know that Marques made 2 three-point shots, we can substitute this value into equation 2 to get:

To set up the iterated integral for evaluating the given expression over the region D, we first need to express the limits of integration for the variables r, θ, and z in terms of the geometry of the region.

From the given information, we know that the region D is a solid right cylinder whose base is the region between the circles r = 3sinθ and r = 3cosθ, and whose top lies in the plane z = 10 - 2sinθ.

The limits of integration for z will be from the bottom of the cylinder to its top, which is from z = 0 to z = 10 - 2sinθ.

The limits of integration for r will be from the inner circle to the outer circle, which is from r = 3sinθ to r = 3cosθ.

Finally, the limits of integration for θ will be from 0 to 2π, since we need to cover the entire circular base of the cylinder.

Therefore, the iterated integral for evaluating the given expression over the region D is:

∫_{0}^{2π} ∫_{3sinθ}^{3cosθ} ∫_{0}^{10-2sinθ} z f(r,θ,z) dz r dr dθ

To calculate the probability of selecting 3 brown plain M&M's in a row, we need to first find the probability of selecting a brown M&M on the first pick, which is 13/52 (since there are 13 brown M&M's out of 52 total M&M's).

Then, for the second pick, there will be one less M&M in the bag and one less brown M&M, so the probability of selecting a brown M&M on the second pick is 12/51. Finally, for the third pick, there will be two less M&M's in the bag and two less brown M&M's, so the probability of selecting a brown M&M on the third pick is 11/50.

Using the formula P(A|B) = P(A and B) / P(B), we can find the conditional probability of A given B:

P(A|B) = P(A and B) / P(B) = 0.20 / 0.40 = 0.5

To check if A and B are independent, we need to see if P(A|B) = P(A).

P(A) = 0.30

P(A|B) = 0.50

Since P(A|B) is not equal to P(A), A and B are not independent.

The probability of at least one foul-up occurring can be found using the formula:

P(at least one foul-up) = 1 - P(no foul-up)

P(no foul-up) = P(not A) * P(not B) * P(not C)

= (1 - 0.02) * (1 - 0.01) * (1 - 0.04)

Yes, the set S of all polynomials of the form c1 + c2x + c3x^3, with c1, c2, and c3 belonging to the real numbers (R), is a vector space. To prove this, we need to show that S satisfies the following properties:

1. Closure under addition: Given any two polynomials P1 = a1 + a2x + a3x^3 and P2 = b1 + b2x + b3x^3 in S, their sum P1 + P2 = (a1 + b1) + (a2 + b2)x + (a3 + b3)x^3 is also in S, since the coefficients are real numbers.

2. Closure under scalar multiplication: Given a polynomial P = c1 + c2x + c3x^3 in S and a scalar k ∈ R, the product kP = (kc1) + (kc2)x + (kc3)x^3 is also in S, as the coefficients are still real numbers.

3. Existence of additive identity: The zero polynomial, 0 = 0 + 0x + 0x^3, is in S, and adding it to any polynomial P in S results in P itself (P + 0 = P).

4. Existence of additive inverse: Given a polynomial P = c1 + c2x + c3x^3 in S, its additive inverse -P = (-c1) + (-c2)x + (-c3)x^3 is also in S. Adding P and -P results in the zero polynomial (P + (-P) = 0).

The sample variance of bottle weight is 2.80.The sample variance is a measure of how spread out the data is from the mean. In this case, the sample variance of 2.80 means that the bottle weights vary quite a bit from the sample mean of 4 grams.  

To find the sample variance, first we need to calculate the sample mean, which is (4+2+5+4+5+2+6)/7 = 4.

Then, we subtract the sample mean from each observation, and square each of the differences: (4-4)^2, (2-4)^2, (5-4)^2, (4-4)^2, (5-4)^2, (2-4)^2, and (6-4)^2.

The sum of these squared differences is 28. Finally, we divide this sum by n-1 (where n is the sample size) to get the sample variance: 28/6 = 2.80.

To find the derivative of the given function f(x), we can use the product rule of differentiation. Let's start by taking the natural logarithm of f(x) to simplify the calculation:

ln[f(x)] = ln[[tex](2-10x)(2-10x^2)(2-10x^3)(2-10x^4)(2-10x^5)(2-10x^6)[/tex]]

Now, we can take the derivative of both sides using the chain rule and product rule of differentiation:

[d/dx] ln[f(x)] = [d/dx] [tex][ln(2-10x) + ln(2-10x^2) + ln(2-10x^3) + ln(2-10x^4) + ln(2-10x^5) + ln(2-10x^6)][/tex]

d[f(x)]/f(x) = [tex]1/(2-10x) + 1/(2-10x^2) + 1/(2-10x^3) + 1/(2-10x^4) + 1/(2-10x^5) + 1/(2-10x^6)[/tex]

Now, we can evaluate f'(1) by substituting x=1 into the above expression:

d[f(x)]/dx| x=1 = 1/(2-10) + 1/(2-10) + 1/(2-10) + 1/(2-10) + 1/(2-10) + 1/(2-10)

= -10/(-8) - 20/(-8) - 30/(-8) - 40/(-8) - 50/(-8) - 60/(-8)

The dimensions of the rectangle are 14 m by 7 m, and the minimum perimeter is: P = 14 + 2(7) = 28 m.

To find the minimum perimeter and dimensions of the enclosure, we can use the formula for the area of a rectangle: A = lw, where A is the area, l is the length, and w is the width.

Let's call the length of the rectangle x, and the width y. Since the fence will only have three sides, we know that one side of the rectangle will be the river. Therefore, the perimeter of the fence will be:

P = x + 2y

We want to minimize the perimeter, so we need to minimize the expression x + 2y. To do this, we can use the fact that the area is given as 98 m^2. We can set up an equation for the area in terms of x and y:

xy = 98

Now we can solve for one of the variables in terms of the other. Let's solve for y:

y = 98/x

Substituting this expression for y into the expression for the perimeter, we get:

P = x + 2(98/x)

To minimize P, we can take the derivative with respect to x and set it equal to zero:

dP/dx = 1 - 196/x^2 = 0

(1)  The samples being compared should be independent of each other.

(2) The populations from which the samples are drawn should follow a normal distribution.

(3) The two samples being compared should have equal variances.

To use a two-sample f-test, three conditions must be met.

Firstly, the samples being compared should be independent of each other. Independence means that the observations in one sample do not influence or depend on the observations in the other sample. This condition is important to ensure that the variability between the samples is not confounded or biased by any relationship or dependence between the observations.

Secondly, the populations from which the samples are drawn should follow a normal distribution. The assumption of normality is required for the f-test to accurately assess the differences in means between the two groups. If the data deviates significantly from a normal distribution, alternative non-parametric tests may be more appropriate.

Finally, the two samples being compared should have equal variances. This assumption, known as the assumption of equal variances or homogeneity of variances, implies that the variability within each group is similar. Violation of this assumption can affect the accuracy of the f-test results. In cases where the variances are unequal, modified versions of the f-test, such as the Welch's t-test, can be used.

In summary, the three conditions for using a two-sample f-test are independence between samples, normality of the populations, and equality of variances. These conditions ensure that the f-test accurately evaluates the differences in means between the two groups being compared.

2) To find the time it takes for the arrow to hit the ground, we need to find the value of t when h(t) = 0. This is because when the arrow hits the ground, its height is zero. So we can set h(t) = 0 and solve for t:

-9.8t² + 32t + 3 = 0

Using the quadratic formula, we get:

t = (-32 + √(32² - 4(-9.8)(3))) ÷ (2(-9.8))

t = (-32 +√(1280.4)) ÷ (-19.6)

t = 3.27

3) To find the time when the arrow is 10 meters in the air, we need to solve the equation h(t) = 10 for t:

-9.8t² + 32t + 3 = 10

-9.8t² + 32t - 7 = 0

Using the quadratic formula, we get:

t = (-32 +√(32² - 4(-9.8)(-7))) ÷ (2(-9.8))

t = (-32 + √(1033.6)) ÷ (-19.6)

t = 0.63

The tangent line has the largest slope at x = √(32/5), with a slope of approximately 254.86.

To find the point on the line 3x + 5y + 5 = 0 which is closest to the point (5,2), we need to use the formula for the distance between a point and a line. The formula is:

distance = |ax + by + c| / √(a² + b²)

where (a,b) is the direction vector of the line and (x,y) is any point on the line. In this case, the direction vector is (3,5) and we can find a point on the line by setting y = 0:

3x + 5(0) + 5 = 0
x = -5/3

So the point on the line closest to (5,2) is:

distance = |3(-5/3) + 5(0) + 5| / √(3² + 5²) = 4 / √34

To find the value(s) of x on the curve y = -7 + 160x³ - 3x^5 where the tangent line has the largest slope, we need to find the derivative of y with respect to x and set it equal to zero:

y' = 480x² - 15x^4
480x² - 15x^4 = 0
x²(32 - 5x²) = 0
x = 0 or x = ±√(32/5)

We can now find the slope of the tangent line at each of these values of x:

slope at x = 0: y' = 0, so the tangent line is horizontal and has slope 0
slope at x = √(32/5): y' = 480(32/5) - 15(32/5)³ ≈ 254.86
slope at x = -√(32/5): y' = 480(32/5) - 15(-32/5)³ ≈ -254.86

Answer: y-axis, because the x-coordinate is the opposite

Step-by-step explanation:

If we are reflecting a coordinate, the resulting coordinate(s) that end up as the opposite form of themselves correspond to the opposite axis. This means that if the x-coordinate is becoming opposite, we are reflecting over the y axis.

Dividing this figure into rectangles, and then adding the areas of those rectangles:

4(24) + 4(12) + 8(8) + 16(16)

= 96 + 48 + 64 + 256 = 464 square units

The angular coordinate, angular velocity, and angular acceleration of the flywheel are: (a) At t = 0, θ = θ0 = 0.5 rad, ω = 0, and α = 12π²θ0 = 23.55 rad/s².

(b) At t = 0.125 s, θ = 0.267 rad, ω = 4.116 rad/s, and α = -69.08 rad/s².

The given equation for the angular displacement of the flywheel is θ=θ0e(-3πcos(4πt)). Here, θ0 = 0.5 rad. To find the angular velocity and angular acceleration, we need to differentiate θ with respect to time.

θ = θ0e(-3πcos(4πt))

ω = dθ/dt = -12π²θ0e(-3πcos(4πt))sin(4πt)

α = d²θ/dt² = -48π³θ0e(-3πcos(4πt))(cos(4πt) - 2)sin(4πt)

Substituting t = 0, we get:

(a) At t = 0, θ = θ0 = 0.5 rad, ω = dθ/dt = 0, and α = d²θ/dt² = 12π²θ0 = 23.55 rad/s².

(b) At t = 0.125 s, θ = 0.267 rad, ω = dθ/dt = 4.116 rad/s, and α = d²θ/dt² = -69.08 rad/s².
