Answer:

h = V/B

Step-by-step explanation:

\(\sf V \div B = h\\Reverse\\h = V \div B\)

Answer:

D. h = V/B

Step-by-step explanation:

"Solve...for h" means get h all by itself on one side of the equation.

V = Bh

Divide both sides by B.

V/B = h

Turn it around and you can see the answer in the choices. D. h = V/B is the correct answer.

To develop a 95% confidence interval for the mean monthly rent for all studio apartments in College Town, we can use the following formula:

CI = x ± z*(σ/√n)

where:
- CI is the confidence interval
- x is the sample mean ($490.80)
- z* is the z-score for a 95% confidence level (1.96)
- σ is the known population standard deviation ($55)
- n is the sample size (70)

Plugging in the values, we get:

CI = $490.80 ± 1.96*($55/√70)
CI = $490.80 ± $12.15

Therefore, the 95% confidence interval for the mean monthly rent for all studio apartments in College Town is $478.65 to $503.95. We can be 95% confident that the true population mean monthly rent for all studio apartments in College Town falls within this range.
Based on the provided information, we can construct a 95% confidence interval for the mean monthly rent of studio apartments in College Town. Here are the relevant terms and values:

- Sample size (n): 70 apartments
- Sample mean (x): $490.80
- Population standard deviation (σ): $55

To calculate the confidence interval, we will use the formula:

Confidence interval = x ± (z * (σ / √n))

For a 95% confidence interval, the z-value is 1.96. Now, let's plug in the values:

Confidence interval = $490.80 ± (1.96 * ($55 / √70))

Confidence interval = $490.80 ± ($13.61)

So, the 95% confidence interval for the mean monthly rent for all studio apartments in College Town is approximately $477.19 to $504.41. This means that we can be 95% confident that the true mean rent for all studio apartments in this city falls within this range.

Step-by-step explanation:

it is complating squer method that used for solving x in a quadratic equetion . in this step you will add

(y/2)^2 if y is the cofitient of x .

The solutions to the equation -30x² + 9x + 60 = 0 are x = 5/2 and x = -4/5.

To solve the equation, we can start by bringing all the terms to one side to have a quadratic equation equal to zero. Let's go step by step:

-5/3 x² + 3x + 11 = -9 + 25/3 x²

First, let's simplify the equation by multiplying each term by 3 to eliminate the fractions:

-5x² + 9x + 33 = -27 + 25x²

Next, let's combine like terms:

-5x² - 25x² + 9x + 33 = -27

-30x² + 9x + 33 = -27

Now, let's bring all the terms to one side to have a quadratic equation equal to zero:

-30x² + 9x + 33 + 27 = 0

-30x² + 9x + 60 = 0

Finally, we have the quadratic equation in standard form:

-30x² + 9x + 60 = 0

Dividing each term by 3, we get:

-10x² + 3x + 20 = 0

(-2x + 5)(5x + 4) = -10x² + 3x + 20

So, the factored form of the equation -30x² + 9x + 60 = 0 is:

(-2x + 5)(5x + 4) = 0

Now we can set each factor equal to zero and solve for x:

-2x + 5 = 0 --> x = 5/2

5x + 4 = 0 --> x = -4/5

The form (x - p)^2 = q is the form that completing the square will leave us with.

---Add 5 to both sides

x^2 - 8x = 5

---Divide the b term by 2, and square it. Then, add that number to both sides.

-8/2 = -4

(-4)^2 = 16

x^2 - 8x + 16 = 5 + 16

x^2 - 8x + 16 = 21

---Factor!

(x - 4)^2 = 21

p = 4

q = 21

Hope this helps!! :)

P and q have values of 4 and 21, respectively.

In mathematics, expression is defined as the relationship of numbers, variables, and functions using mathematical signs such as addition, subtraction, multiplication, and division.

The form (x - p)²= q is what we get when we complete the square.

Adding the number 5 on both sides,

x² - 8x = 5

After dividing by two, square the b term. Then divide both sides by that figure.

-8/2 = -4

(-4)² = 16

x² - 8x + 16 = 5 + 16

x² - 8x + 16 = 21

Solve the factors,

(x - 4)² = 21

p = 4

q = 21

As a result, the values of p and q are 4 and 21, respectively.

Answer:

\(4\sqrt{21}\)

Step-by-step explanation:

Pythagorean theorem is \(a^{2} +b^{2} =c^{2}\).

Which in this case:

'c' is hypotenuse. (hypotenuse = 20)

'a' and 'b' are the other sides. (a = x, b = 8)

Now we should just take square root from the both sides.

and the answer will be \(\sqrt{336}\) or \(-\sqrt{336}\), but a side of a triangle can not be a negative number! so the answer will be \(\sqrt{336}\).

As you see \(\sqrt{336}\) is not the simplest radical.

We can write \(\sqrt{336}\) as \(\sqrt{16 * 21}\).

And from the laws of radical we can write \(\sqrt{16*21}\) as \(\sqrt{16} * \sqrt{21}\).

\(\sqrt{16} * \sqrt{21} = \sqrt{16}\sqrt{21} = 4\sqrt{21}\)

a. The equation of the reflected graph is y = -34

b. The equation of the shifted graph is y = 34

c. The equation of the shifted graph is y = 42.

A mathematical definition of an equation is a claim that two expressions are equal when they are joined by the equals sign ("="). For illustration, 2x - 5 = 13. 2x - 5 and 13 are expressions in this case. These two expressions are joined together by the sign "=".

a. Reflecting f(t) about the y-axis:

When we reflect a function about the y-axis, we change the sign of the x-values while keeping the y-values the same. Therefore, the equation of the reflected graph is:

y = -34

b. Shifting f(x) 9 units to the right:

To shift a function 9 units to the right, we replace t with (t - 9) in the equation. Therefore, the equation of the shifted graph is:

y = 34

c. Shifting f(x) 8 units upward:

To shift a function 8 units upward, we add 8 to the equation. Therefore, the equation of the shifted graph is:

y = 34 + 8

y = 42

(a) A nonzero vector orthogonal to the plane through the points P, Q, and R is (9, -17, 35). (b) The area of triangle PQR is \(\sqrt\)(811) / 2.

(a) To determine a nonzero vector orthogonal to the plane through the points P, Q, and R, we can first find two vectors in the plane and then take their cross product. Taking vectors PQ and PR, we have:

PQ = Q - P = (5, 1, -2) - (-4, 0, 0) = (9, 1, -2)

PR = R - P = (6, 4, 1) - (-4, 0, 0) = (10, 4, 1)

Taking the cross product of PQ and PR, we have:

n = PQ x PR = (9, 1, -2) x (10, 4, 1)

Evaluating the cross product gives n = (9, -17, 35). Therefore, (9, -17, 35) is a nonzero vector orthogonal to the plane through points P, Q, and R.

(b) To determine the area of triangle PQR, we can use the magnitude of the cross product of vectors PQ and PR divided by 2. The magnitude of the cross product is given by:

|n| = \(\sqrt\)((9)^2 + (-17)^2 + (35)^2)

Evaluating the magnitude gives |n| = \(\sqrt\)(811).

The area of triangle PQR is then:

Area = |n| / 2 = \(\sqrt\)(811) / 2.

Answer:

A. \( 82\degree\)

Step-by-step explanation:

By the theorem of intersecting chords inside a circle.

\( m\angle OVU=\frac{1}{2} (m\widehat {GK} +m \widehat {OU}) \)

\( m\angle OVU = \frac{1}{2} (142\degree + 54\degree) \)

\( m\angle OVU=\frac{1}{2} \times 196\degree \)

\( m\angle OVU = 98\degree \)

\( m\angle OVU + m\angle OVU = 180\degree \)

(Linear pair angles)

\(m\angle OVG + 98\degree = 180\degree \)

\( m\angle OVG =180\degree - 98\degree\)

\( m\angle OVG = 82\degree\)

The equation of g(x) is \(\mathbf{g(x) = 8(2)^x}\)

A geometric function is represented as:

\(\mathbf{y =ab^x}\)

The graph of g(x) passes through (-1,4) and (-2,2)

So, we have:

\(\mathbf{2 =ab^{-2}}\)

\(\mathbf{4 =ab^{-1}}\)

Divide both equations

\(\mathbf{\frac{4}{2} =\frac{ab^{-1}}{ab^{-2}}}\)

Divide

\(\mathbf{2 =b}\)

Rewrite as:

\(\mathbf{b =2}\)

Substitute 2 for b in \(\mathbf{4 =ab^{-1}}\)

\(\mathbf{4 = a2^{-1}}\)

Multiply both sides by 2

\(\mathbf{8 = a}\)

Rewrite as:

\(\mathbf{a = 8}\)

Substitute 2 for b and 8 for a in \(\mathbf{y =ab^x}\)

\(\mathbf{y = 8(2)^x}\)

Express as a function

\(\mathbf{g(x) = 8(2)^x}\)

Hence, the equation of g(x) is \(\mathbf{g(x) = 8(2)^x}\)
