The total fabric required to make a tent in the shape of a triangular prism with the given measures is 1162 square feet.

To calculate the amount of fabric required to make a tent in the shape of a triangular prism, we need to calculate the surface area, which is essentially the sum of the areas of all the faces.

The measures provided are presumably the areas of each of the faces of the triangular prism (273 ft^2, 329 ft^2, 294 ft^2, and 266 ft^2). In which case, we simply add these areas together:

273 ft^2 + 329 ft^2 + 294 ft^2 + 266 ft^2 = 1162 ft^2

Therefore, the total fabric required is 1162 square feet.

To calculate the amount of fabric needed for a triangular prism-shaped tent, find the area of each face and add them together.

To find the amount of fabric needed to make a triangular prism-shaped tent, we need to calculate the surface area of all the faces. A triangular prism has two triangular bases and three rectangular faces. First, find the area of each face: base = 273 ft2, height = 329 ft2, and second base = 294 ft2. Then, calculate the area of the three rectangular faces: length = height of the triangular face = 329 ft2, and the other two lengths are the same as the base or second base.

So, the total fabric needed is the sum of the areas of all the faces. Add the areas of the two triangular faces and the three rectangular faces to find the final answer.

Answer:

[tex]SinA = \frac{84}{85}[/tex]  and  [tex]CosA=\frac{13}{85}[/tex]

Step-by-step explanation:

The ratios of sine and cos are defined as follows:

[tex]Sin A = \frac{Opposite}{Hypotenuse}[/tex] , and

[tex]CosA = \frac{Adjacent}{Hypotenuse}[/tex]

The hypotenuse is always the side opposite of the 90 degree angle (for the given triangle, the hypotenuse is 85)

Since we are looking at the angle A, the opposite side with respect to A would be the side length of 84. That leaves the side 13 as the adjacent side.

Thus, we can now write:

[tex]Sin A = \frac{Opposite}{Hypotenuse}\\SinA = \frac{84}{85}[/tex]

[tex]CosA = \frac{Adjacent}{Hypotenuse}\\CosA=\frac{13}{85}[/tex]

Answer:

A

Step-by-step explanation:

An equivalent expression is an expression which is equal to (x-9)(2x^2-6x+3). You can expand or simplify an expression to make an equivalent expression. Apply the distributive property to form a new equivalent expression by multiplying (x-9) separately into the factor in parenthesis.

(x-9)(2x^2-6x+3)  = x(2x^2-6x+3) - 9(2x^2-6x+3)

(f/g)(-5) = 5

Step-by-step explanation:

You mean, "determine the value of (f/g)(x) at x = -5."

That would be:

f(x)        2x - 20

------- = ------------   and we now substitute -5 for x:

g(x)         x - 1

                  2(-5) - 20      -30

 (f/g)(-5) = --------------- = -------- = 5

Answer:

Step-by-step explanation:

Since n < 30, we will find the t-score and compare that to the t-score of a significance level of 1%.    

Since they are asking if the difference is significant, we will have a two tailed test, with degree of freedom being 22, so our critical values are

t < -2.704 and t > 2.704

Our t-value for this situation is

t = ([µ + 5.8] - µ)/(1.4/√23)

It's µ + 5.8 because the problem told us that their levels are 5.8 mm higher than the average, so it's the average, plus 5.8

Simplify the equation...

t = 5.8/(1.4/√23)

t = 19.868

19.868 > 2.704, the evidence supports that there is significant difference between the sample and the population

There is a significant difference between the sample and the population.

A standard deviation (or σ) indicates how dispersed the data is in relation to the mean.

The t-distribution indicates the standardized distances of sample means to the population mean when the population standard deviation is not known, and the observations come from a normally distributed population.

A t-score is the number of standard deviations away from the mean of the t-distribution.

Here the degree of freedom is 22 and so the critical values are:

t < -2.704 and t > 2.704

∴ The t-value for this situation is

t = ([µ + 5.8] - µ)/(1.4/√23)

⇒ t = 5.8/(1.4/√23)

⇒t = 19.868

So, we can say that there is significant difference between the sample and the population.

For each exponent inside the radical, you will divide it over the root index. The root index is the small number to the left and above the radical symbol. So the root index is 6 in this case.

Divide each exponent over 6

18/6 = 3 is the final exponent for y

Answer:

The answer is vertical translation down 9 units  ⇒ answer (d)

Step-by-step explanation:

* Lets talk about the transformation

- If the function f(x) translated horizontally to the right  

 by h units, then the new function g(x) = f(x - h)

- If the function f(x) translated horizontally to the left  

 by h units, then the new function g(x) = f(x + h)

- If the function f(x) translated vertically up  

 by k units, then the new function g(x) = f(x) + k

- If the function f(x) translated vertically down  

 by k units, then the new function g(x) = f(x) - k

* Lets study the problem

- The basic function is y = csc(x)

∵ y = csc(x) - 9

- That means the function translated vertically 9 units down

* Vertical translation 9 units down

* Look to the graph

-The red graph is y = csc(x)

- The green graph is y = csc(x) - 9

The solution to the given system of linear equations is (3, 2), which is found by eliminating y and solving for x, then substituting back to find y.

Given the system of equations:

x + 2y = 7
x - 2y = -1

To find the solution to the system, we can add the two equations to eliminate y:

(x + 2y) + (x - 2y) = 7 + (-1)
2x = 6
x = 3

Substituting x = 3 into the first equation:

3 + 2y = 7
2y = 4
y = 2

So, the solution to the system of equations is (3, 2). None of the other provided options, {(-8, -12)} or {(-4, 6)}, match this solution.

x =  1.144

The question requires solving a trigonometric equation tan x = 2 csc x by using trigonometric identities to express it in terms of sine and cosine and then finding the approximate solutions within the interval -π to π.

The student is asking for an approximate solution for a trigonometric equation within a specified interval. The equation given is tan x = 2 csc x. To solve this trigonometric equation, you need to use trigonometric identities to express both sides of the equation in terms of a single trigonometric function and then find the values of x that satisfy the equation within the given interval.

To start with, we can use the identity csc x = 1/sin x and then rewrite the equation as tan x = 2/sin x. Since tan x = sin x/cos x, we can now express the equation purely in terms of sine and cosine:

sin x/cos x = 2/sin x

Multiplying both sides by sin x cos x, we obtain sin2 x = 2 cos x. From here, we can use numerical methods or graphing techniques to find an approximate solution for x within the interval -π to π.

Answer:

(-2, 0)

Step-by-step explanation:

Because both equations are to find Y, set them equal to each other to solve:

3x+6 = x+2

Subtract x from both sides:

2x + 6 = 2

Subtract 6 from both sides:

2x = -4

Divide both sides by 2:

x = -4 /2

x = -2

Now you have a value for x, replace X with -2 in one of the equations and solve for y:

y = 3x +6 = 3(-2) +6 = -6 +6 = 0

X = -2 and Y = 0

(-2,0)
