Answer:

The original price is $40.00.

Step-by-step explanation:

I am not sure what that given equation is.

But here is the correct answer and steps.

The marked down price is 75% of the original price.

The final price is 90% of the marked down price.

Lets say

\(T\) = Final Price

\(O\) = Original Price

We can write

\(T=(0.75*O)*(0.9)\)

Multiply \(0.9\) by \(0.75\).

\(T=0.675*O\)

We are given the final price. Lets substitute 27.00 for \(T\).

\(27.00=0.675*O\)

Divide both sides of the equation by \(0.675\).

\(40.00=O\)

The radius of the circle which is overlapping the square is 1.12.

The length of side of the square is 2. Let us say that the radius of the circle is R.

The circle and the square are overlapping on each other.

The area of the region that are outside the circle but inside the square are equal to the area of the region which are inside the circle but outside the square.

Let us name the area of the region that are outside the circle but inside the square as M.

Let us name the area of the region which are inside the circle but outside the square as N.

Let us say that the area that is common in both is C.

The area of the square is 4.

So, according to the question,

M + C = 4

And,

N + C = πR²

And we know, M = N,

So,

C - πR² = C - 4

R = 2/√π

R = 1.12.

So, the radius of the circle is 1.12

Step-by-step explanation:

The critical region is determined based on the alpha level, which is the probability of making a Type I error (rejecting the null hypothesis when it is true). An alpha level of .01 means that there is a 1% chance of making a Type I error.

If Chastity ran a hypothesis test with an alpha level of .01 and her test statistic fell outside of the critical region, it means that the test statistic does not provide enough evidence to reject the null hypothesis.

In this case, Chastity should fail to reject the null hypothesis and accept it as the plausible explanation. This implies that there is not enough evidence to support the alternative hypothesis.

When a test statistic falls outside of the critical region, it indicates that the observed data is not extreme enough to reject the null hypothesis. The critical region is determined based on the alpha level, which is the probability of making a Type I error (rejecting the null hypothesis when it is true). An alpha level of .01 means that there is a 1% chance of making a Type I error.

It takes 2 years for the account balance to come down to 0.

Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.

The formula used to find the compound interest = \(A=P(1+\frac{r}{100})^{nt}\).

Given that, principal =$20,000, rate of interest =1.56%, n=52 and W=$200.

Use the formula, \(P=W\frac{1-(1+\frac{r}{n})^{-nt} }{\frac{r}{n} }\)

\(20000=200\frac{1-(1+\frac{0.0156}{52})^{-52t} }{\frac{0.0156}{52} }\)

\(100=\frac{1-(1+0.0003)^{-52t}}{0.0003}\)

\(0.03=1-(1.0003)^{-52t}\)

\(0.97=(1.0003)^{-52t}\)

Take log on both the side, we get

Check the picture below.

The second derivative of f(x) = 3sin(2x) is f''(x) = -12sin(2x). The second derivative is obtained by taking the derivative of the first derivative.

In this case, we start by finding the first derivative of f(x) and then differentiate it once again. To find the first derivative, we apply the chain rule. The derivative of sin(2x) is cos(2x) multiplied by the derivative of the inner function, which is 2. Therefore, the first derivative of f(x) = 3sin(2x) is f'(x) = 3(2cos(2x)) = 6cos(2x).

Next, to find the second derivative, we differentiate f'(x) = 6cos(2x) using the chain rule again. The derivative of cos(2x) is -sin(2x) multiplied by the derivative of the inner function, which is 2. Thus, the second derivative of f(x) is f''(x) = 6(-2sin(2x)) = -12sin(2x).

In summary, the second derivative of f(x) = 3sin(2x) is f''(x) = -12sin(2x). The process involves finding the first derivative using the chain rule and then differentiating it once more using the chain rule as well.

Angle: An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively.

Therefore first image is ∠ABC.

In mathematics, a ray is a segment of a line with a fixed starting point but no ending.

The fixed point is B. Then second image represents \(\overrightarrow{BA}\). The sixth image represents two rays that are \(\overrightarrow{BC}\) and \(\overrightarrow{BA}\),

A point is a basic concept in traditional Euclidean geometry that represents an exact place in space and has no length, breadth, or thickness. In contemporary mathematics, a point more broadly refers to a component of a set known as a space.

The image represent point C.

A plane is an infinitely long, Euclidean, two-dimensional surface in mathematics. A plane is a point, a line, and three-dimensional space's equivalent in two dimensions.

The intersection is when both functions have same coordinates

Substitute to get

The y- coordinate is

So the intersection point is (1, 14)

Answer:

(1, 14)

Step-by-step explanation:

Given functions:

\(\begin{cases}f(x)=-2x+16\\g(x)=4x+10\end{cases}\)

Substitute the function notation for y to create a system of equations:

\(\begin{cases}y=-2x+16\\y=4x+10\end{cases}\)

To find the points of intersection of the given functions, solve the system of equations.

Multiply the first equation (function f(x)) by 2:

\(\implies 2y=-4x+32\)

Add this to the second equation (function g(x)) to eliminate x:

\(\begin{array}{r l}4x+10 & = y\\+ \quad -4x+32 & = 2y\\\cline{1-2} 42 & = 3y\end{array}\)

Solve for y:

\(\implies 3y=42\)

\(\implies y=14\)

Substitute the found value of y into one of the equations and solve for x:

\(\implies 4x+10=14\)

\(\implies 4x=4\)

\(\implies x=1\)

Therefore, the point of intersection of the given functions is (1, 14).

The function g(x) = (x+2)^2 - 1 can be graphed by starting with the graph of the function y = x^2 and then shifting it 2 units to the left and down 1 unit.

The function y = x^2 is a parabola that is symmetric about the y-axis. When we shift it 2 units to the left, the parabola will move 2 units to the left without changing its shape. The new parabola will have a vertex at the point (-2, 0).

When we shift the parabola down 1 unit, the parabola will move 1 unit down without changing its shape. The new parabola will have a vertex at the point (-2, -1).

The graph of the function g(x) = (x+2)^2 - 1 is the graph of the shifted and reflected parabola.

Step-by-step explanation:

Gerard concluded that triangle with given sides cannot be used as  building-frame support because it is not right triangle, he come to this conclusion because the Pythagoras-theorem is not satisfied.

In order to check if a triangle is "right-triangle", Gerard used the Pythagorean theorem. According to this theorem, in right triangle, the square of length of hypotenuse (the side opposite the right angle) is equal to sum of squares of other two sides,

So, the squares of the given sides are :

Square of √95 feet = (√95)² = 95 feet

Square of 8 feet = 8² = 64 feet

Square of √150 feet = (√150)² = 150 feet

We see that, 95 feet + 64 feet = 159 feet ≠ 150 feet,

Since the square of the longest side (√150) is not equal to the sum of the squares of the other two sides (√95 and 8), the Pythagorean-theorem is not satisfied.

Therefore, Gerard concluded that the triangle with sides √95 feet, 8 feet, and √150 feet is not a right triangle.

The given question is incomplete, the complete question is

Gerard concluded that the triangle with sides √95 feet, 8 feet, and √150 cannot be used as a building frame support on the house because it is not a right triangle. How did Gerard come to that conclusion? explain.

All of these questions require one thing: trigonometric functions.

There are 3 main trigonometric functions, which can only be used on right triangles: sine, cosine, and tangent.

Sine = opposite / hypotenuse

Cosine = adjacent / hypotenuse

Tangent = opposite / adjacent

When trying to figure out what function to use, we always start by looking from the angle. Take problem a, for example. Looking from angle E, of which the value is not given, we have the side opposite and the side adjacent. Therefore, we should use the tangent function.

---The hypotenuse is always the longest side of the triangle. It is never considered the opposite or adjacent side.

Let's set up our function with the given information from problem a.

tan(x) = 9.7 / 5.2

---The tangent of an unknown angle is equal to the quotient of the opposite side and the adjacent side.

Now, solving for the value of x will require a calculator. We'll need to use what's called an inverse trigonometric function. Most calculators have these directly above the regular trigonometric functions, and the inverse functions are accessed using a "second" key.

---Ensure that your calculator is in degrees, not radians!

x = tan^-1(9.7 / 5.2)

x = 61.805 = 62 degrees

Next, let's take a look at problem b. This time, we're solving for a side length instead of an angle. But, we're still going to start by looking from our angle.

Looking from the 38 degree angle, we are given the adjacent side and an unknown hypotenuse. Therefore, we should use the cosine function.

cosine(38) = 53.1 / r

---The cosine of a 38 degree angle is equal to the quotient of 53.1 and an unknown hypotenuse, r.

Use your algebra skills to isolate the variable r.

r * cosine(38) = 53.1

r = 53.1 / cosine(38)

---From here, all you need to do is plug this into your calculator. Since we are solving for a side length (and given an angle), we are just using the regular trigonometric function buttons on the calculator.

r = 67.385 = 67.4 units
