Answer:

x = 13

Step-by-step explanation:

First start with the blank equation

\(a^{2} + b^{2} = c^{2}\)

Plug in the legs and hypotenuse. Remember c squared is always the hypotenuse.

\(5^{2} + 12^{2} = c^{2}\)

Then solve

25 + 144 = \(c^{2}\)

169 =\(c^{2}\)

\(\sqrt{169} = \sqrt{c^{2} }\)

c = 13

To find the indefinite integral of ∫(5/x - 5/(5√x)) dx, we will integrate each term separately. The indefinite integral of (5/x - 5/(5√x)) with respect to x, on the domain of positive real numbers, is given by 5 ln |x| - 2√x + C.

The integral of 5/x with respect to x is given by:

∫(5/x) dx = 5 ln |x| + C1,

where ln represents the natural logarithm and C1 is the constant of integration.

The integral of -5/(5√x) can be simplified as follows:

∫(-5/(5√x)) dx = -∫(1/√x) dx = -2√x + C2,

where C2 is the constant of integration.

Putting the results together, we have:

∫(5/x - 5/(5√x)) dx = 5 ln |x| - 2√x + C,

where C = C1 + C2 is the combined constant of integration.

Therefore, the indefinite integral of (5/x - 5/(5√x)) with respect to x, on the domain of positive real numbers, is given by 5 ln |x| - 2√x + C.

Answer: 257

Step-by-step explanation: Theres no remainder, and u couldve used a calculator

Answer:

257

Step-by-step explanation:

2056 : 8 = 257

Louisa would need to invest $32,172.75 semiannually to have $44000 in four years if the fund she has selected pays 8.1% annually, compounded semiannually.

To have $44000 in four years, Louisa would need to invest a total of $x in the fund that pays 8.1% annually, compounded semiannually.

Using the formula for compound interest, we can solve for x:

A = P(1 + r/n)^(nt)

Where:
A = the total amount (in this case, $44000)
P = the principal amount (the amount Louisa needs to invest)
r = the annual interest rate (8.1%)
n = the number of times the interest is compounded per year (semiannually = 2)
t = the number of years (4)

Plugging in these values:

44000 = P(1 + 0.081/2)^(2*4)

44000 = P(1.0405)^8

44000 = P(1.366)

P = 32172.75

So Louisa would need to invest $32,172.75 semiannually to have $44000 in four years if the fund she has selected pays 8.1% annually, compounded semiannually.

To solve the first-order differential equation

(cos F) * (dF/dx) + (sin F) * P(x) + (1/sin F) * q(x) = 0,

we can rearrange the terms and separate the variables. Here's how we proceed:

Integrating both sides, we obtain:

∫ (dF/cos F) = - ∫ ((sin F) * P(x) + (1/sin F) * q(x)) dx.

The left-hand side integral can be evaluated using the substitution u = cos F, du = -sin F dF:

∫ (dF/cos F) = ∫ du = u + C1,

where C1 is the constant of integration.

For the right-hand side integral, we have:

∫ ((sin F) * P(x) + (1/sin F) * q(x)) dx = - ∫ (sin F * P(x)) dx - ∫ (1/sin F * q(x)) dx.

We'll solve this equation:

First, let's apply the distributive property:

‎      ‏‏‎5x + 17 = 4(3x - 1)

‎      ‏‏‎5x + 17 = 12x - 4

Now, add 4 to both sides of the equation:

‎      ‏‏‎5x + 17 = 12x - 4

5x + 17 + 4 = 12x - 4 + 4

‎      ‏‏‎5x + 21 = 12x

Ndidi rides y km at 10 km/hr, then walks 0.5y km at 3 km/hr. She is away from. home less than 4hours.Range of the values of Y is =24/7

Let's call the total time spent riding and walking t hours. We know that t is less than 4 hours, so:

t = time spent riding + time spent walking < 4 hours

The time spent riding is given by y / 10 km/hr and the time spent walking is given by 0.5y / 3 km/hr. So, we can write the inequality as:

t = y / 10 + 0.5y / 3 < 4

Expanding and simplifying the expression on the left side gives:

7/6y < 4 * 6/7

Multiplying both sides by 6/7 gives:

y < 4 * 6/7 * 6/7 = 24/7

So, the range of values of y is 0 < y < 24/7 km. This means that Ndidi rode less than 24/7 km, but more than 0 km.

By testing these boundary values, you can ensure that the remove current function handles various scenarios correctly. It is important to thoroughly test the function to ensure its robustness and reliability.

The remove current function in the sequence class should be tested with different boundary values to ensure its correct functionality. Here are some good boundary values to consider:

1. Testing when the sequence size is 0:

In this case, you can test the remove current function by trying to remove an item from an empty sequence.

The expected behavior should be that the function does not remove anything and returns an appropriate message or error.

2. Testing when the sequence is at its full capacity minus one:

To test the remove current function in this scenario, you should try removing the first item and the last item in the sequence. This will help verify if the function correctly handles removing items at the boundaries.

Make sure to check if the removal of the first item shifts the remaining items correctly, and if removing the last item updates the sequence size accordingly.

The  polar equation for the curve represented by xy = 8 is:

r^2 = 16 / sin(2theta)

To find a polar equation for the curve represented by the cartesian equation xy = 8, we can use the fact that x = r cos(theta) and y = r sin(theta) in polar coordinates. Substituting these expressions into the cartesian equation, we get:

r cos(theta) * r sin(theta) = 8

Simplifying this expression, we get:

r^2 = 8 / (sin(theta) cos(theta))

Using the identity sin(2theta) = 2 sin(theta) cos(theta), we can rewrite this expression as:

r^2 = 16 / sin(2theta)

Therefore, the polar equation for the curve represented by xy = 8 is:

Yes, the Earth's rotational axis is known to tilt at an angle of approximately 23.5 degrees relative to the plane of its orbit around the Sun.

However, it is highly unlikely for the Earth's rotational axis to be completely perpendicular to the plane of its orbit around the Sun. The Earth's rotational axis is responsible for the occurrence of seasons and the length of daylight hours in different parts of the world. The angle of the tilt also causes variations in the amount of solar radiation received by different regions of the planet, leading to temperature differences that drive atmospheric circulation. While the tilt of the Earth's rotational axis does change over long time periods due to gravitational interactions with other planets, it is highly unlikely for it to ever be completely perpendicular to the plane of its orbit around the Sun due to the stability of the solar system.

The Earth's rotational axis is unlikely to ever be completely perpendicular to the plane of its orbit around the Sun. The angle of the tilt of the Earth's rotational axis plays a crucial role in determining seasonal changes and temperature variations on the planet.

Given the word problem, we can deduce the following information:

1. The total amount is $12.07.

To determine the bills and coins equal to $12.07, we must follow the steps below:

Total = $12.07

So,

We subtract $10 bill since it is the largest bill not larger than the total ($12.07):

$12.07-$10.00= $2.07

We subtract $1.00 since it is the largest bill not larger than the total ($2.07):

$2.07-$1.00= $1.07

We subtract $1.00 since it is the largest bill not larger than the total ($1.07):

$1.07 -$1.00=$0.07

We subtract $0.05(Nickle) since it is the largest bill not larger than the total ($0.07):

$0.07-$0.05= $0.02

We subtract $0.01 (Dime) since it is the largest bill not larger than the total ($0.02):

$0.02-$0.01=$0.01

We subtract $0.01 (Dime) since it is the largest bill not larger than the total ($0.01):

$0.01-$0.01 =0

Therefore, the bills and coins are:

$10 bill =1

$1.00 bill =2

$0.05(Nickle) =1

The approximate area of the semicircle is 100.48 square inches.

Given that the length of the curved part of a semicircle is 25.12 inches, we are to find the approximate area of the semicircle using 3.14 for π.

We can start by using the formula for finding the circumference of a circle.

A semicircle is half of a circle, and its curved part is half the circumference of the corresponding circle.

Circumference of the corresponding circle = 2πr, where r is the radius of the circle.

Circumference of the semicircle = (1/2) × 2πr = πr.

Now, we have πr = 25.12 inches.

We can solve for r:r = 25.12/π ≈ 8 inches.

The area of a semicircle is given by the formula A = (πr²)/2.

Substituting the value of r, we get:

A ≈ (3.14 × 8²)/2 ≈ 100.48 square inches.

Therefore, the approximate area of the semicircle is 100.48 square inches.

The given fraction (x^2-25)/(x^2-x-20) expressed in simplest form is (x+5)/(x+4). (Option C)

A fraction is in simplest form if the numerator and denominator have no common factors other than 1. In order to solve the given fraction, the numerator and denominator must be factorized, and the common factor will be canceled out.

Factoring x^2 – 25 using the difference of squares formula that states that a^2 – b^2 = (a + b)(a - b)

x^2 – 25 = x^2 – 5^2 = (x + 5)(x – 5)

Factoring x^2 – x – 20,

x^2 – x – 20 = x^2 + 4x – 5x – 20 = x(x + 4) -5(x + 4) = (x + 4)(x – 5)

Hence, factor (x – 5) is there in both numerator and denominator, it is canceled out. Hence the fraction in the simplest form is:

(x + 5)(x – 5)/ (x + 4)(x – 5) = (x + 5)/(x + 4)
