hello this is a trigonometry question hopefully you can help I did every thing else it's just the last one I can't get the reference angle for five in this question

Answer:

0.607142857, = About 60 percent

Step-by-step explanation:

When the question says that much out of that, you divide by. For example, 99 out of 102, you do 99 divided by 102. Then just round to the nearest hundredth. So answer of that would be 97 percent.

Answer:

The answer is zero.

Step-by-step explanation:

When you put the coordinates in the point-slope formula, it will be 7 - (-1) over  -2 - (-2), which is 8/0. When the denominator is zero in the fraction, the answer is zero.

The domain and the range of the function are (-∝, ∝) and (0, ∝), respectively

From the question, we have the following parameters that can be used in our computation:

The graph

The above graph is an exponential function

The rule of an function is that

The domain is the set of all real values

In this case, the domain is (-∝, ∝)

For the range, we have

Range = (0, ∝)

Answer is 52

Answer:

Let W be the width of the logo. The area of the rectangular logo is given by:

A = L × W

From the problem, we know that the length of the logo is 1.9 meters, so:

L = 1.9 m / W

We also know that the area of the logo is exactly the maximum area allowed by the building owner, so we can write:

A = max area = 25 m^2

Substituting the expression for L in terms of W, we get:

A = L × W

25 m^2 = (1.9 m / W) × W

Simplifying and solving for W, we get:

25 m^2 = 1.9 m × W

W = 25 m^2 / 1.9 m

W ≈ 13.16 m

Finally, we can use the expression for L in terms of W to find the length of the logo:

L = 1.9 m / W

L ≈ 0.144 m

Therefore, the equation that could be used to determine L, the unknown side length of the logo, is:

L = 1.9 m / W, where W is the width of the logo.

Step-by-step explanation:

To find the values of r for which the function y = e^(rx) satisfies the differential equation y'' + 7y' + 10y = 0, we need to substitute the function into the equation and solve for r.

First, we find the derivatives of y:

y' = d/dx(e^(rx)) = re^(rx)

y'' = d^2/dx^2(e^(rx)) = r^2e^(rx)

Substituting these derivatives into the differential equation, we have:

r^2e^(rx) + 7re^(rx) + 10e^(rx) = 0

We can factor out e^(rx) from this equation:

e^(rx)(r^2 + 7r + 10) = 0

For this equation to hold, either e^(rx) = 0 or (r^2 + 7r + 10) = 0.

Since e^(rx) is always positive and never equal to zero, we focus on the quadratic equation:

r^2 + 7r + 10 = 0

We can solve this quadratic equation by factoring:

(r + 2)(r + 5) = 0

Setting each factor equal to zero, we get two possible solutions:

r + 2 = 0 --> r = -2

r + 5 = 0 --> r = -5

Therefore, the values of r for which the function y = e^(rx) satisfies the differential equation y'' + 7y' + 10y = 0 are r = -2 and r = -5.

To determine the values of r for which the function y = e^(rx) satisfies the equation y'' + 7y' + 10y = 0, we need to find the values of r that make the function a solution to the given differential equation. This can be achieved by substituting the function into the differential equation and solving for r.

By doing so, we can obtain the values of r that satisfy the equation.

The given differential equation is y'' + 7y' + 10y = 0, where y'' represents the second derivative of y with respect to x and y' represents the first derivative of y with respect to x.

We can substitute the function y = e^(rx) into the differential equation to obtain:

(e^(rx))'' + 7(e^(rx))' + 10(e^(rx)) = 0

Differentiating e^(rx) twice yields:

r^2e^(rx) + 7re^(rx) + 10e^(rx) = 0

Factoring out e^(rx), we have:

e^(rx)(r^2 + 7r + 10) = 0

For this equation to hold true for all x, the expression in the parentheses must equal zero. Therefore, we solve the quadratic equation r^2 + 7r + 10 = 0.

Using factoring or the quadratic formula, we find the roots of the equation: r = -2 and r = -5.

Hence, the values of r that make the function y = e^(rx) satisfy the differential equation y'' + 7y' + 10y = 0 are r = -2 and r = -5.

The value of x is for the given trigonometric function is found as: x = 0.1303 + 1/15 *2nπ.

The given expression is:

16 cos(15x) + 8 = 2

On simplification:

cos(15x) = (2-8)/16

cos(15x) = -3/8

15x = arcos ( -3/8 )

15x =  2π -  arcos ( -3/8 )

15x =  arcos ( -3/8 ) + 2nπ  ;or

15x =  2π - arcos ( -3/8 ) + 2nπ ; n ∈ Z

So,

15x = 1.955 + 2nπ

x = 1/15(1.955 + 2nπ)

x = 0.1303 + 1/15 *2nπ , n ∈ Z

Thus, the value of x is found as: x = 0.1303 + 1/15 *2nπ.

A firm experiences increasing returns to scale if inputs are doubled and output more than doubles.

When the firm's output grows at a faster rate than the growth in inputs, increasing returns to scale result. In this case, the company experiences economies of scale, which makes it more effective as it grows its production.

The firm is able to boost productivity and efficiency as it expands its scale of operations if inputs are doubled and output more than doubles.

This can be ascribed to a number of things, including specialisation, labour division, the use of capital-intensive technology, discounts for bulk purchases, and spreading fixed costs over a higher output. Lower average costs per unit of output result in higher profitability and competitiveness for the company.

The firm gains a number of benefits from growing returns to scale. First off, it lets the company to benefit from cost savings brought about by economies of scale, allowing it to manufacture goods or services for less money per unit. This may enable more competitive pricing on the market or result in larger profit margins.

Second, raising returns to scale can result in better operational effectiveness and resource utilisation. As the company grows in size, it will be able to use resources more wisely and profit from production volume-related synergies.market prices that are competitive.

The hiker's elevation after 150 minutes is given as follows:

1998.5 feet.

To find the numeric value of a function or of an expression, we replace each instance of the variable in the function or in the expression by the value at which we want to find the numeric value.

For this problem, the function is given as follows:

y = 9.01x + 647.

Giving the hiker's elevation after x minutes.

Hence the hiker's elevation after 150 minutes is found with the numeric value at x = 150, replacing the lone instance of x by 150, hence:

y = 9.01(150) + 647 = 1998.5 feet.

The circumference of the great circle of the sphere is approximately 31.4 inches.

To find the circumference of the great circle of the sphere with a volume of (500π)/3 cubic inches, we will first find the radius (r) using the volume formula, and then use the circumference formula.

Step 1: Use the volume formula to find the radius.
The volume formula for a sphere is V = (4/3)π\(r^3\). We are given the volume as (500π)/3, so we can set up the equation:

(500π)/3 = (4/3)π\(r^3\)

Step 2: Solve for r.
To solve for r, we can first divide both sides by (4/3)π:

[(500π)/3] / [(4/3)π] = \(r^3\)

Cancelling the π and the 3 from both sides, we get:

500 / 4 = \(r^3\)
125 = \(r^3\)

Now, take the cube root of both sides:

r = 5

Step 3: Use the circumference formula to find the circumference of the great circle.
The circumference formula for a circle is C = πd, and since the diameter (d) is twice the radius, we have:

C = π(2r) = π(2 × 5) = 10π

Step 4: Calculate the circumference using 3.14 for π and round to the nearest tenth.
C = 10 × 3.14 ≈ 31.4
