Answer:

It's 16 yards.

Step-by-step explanation:

20 - 16.16 = $3.84

3.84 = 384 cents

384 : 24 = 16

Kira bought 16 yards of the ribbon, as of the given conditions.

As mentioned in the question, Kira got a prepaid debit card with $20 on it. The price of the ribbon was 24 cents per yard. If after that purchase there was $16.16 left on the card,

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Kira got a prepaid debit card with $20 on it.
After that purchase, there was $16.16 left on the card,
Cost of the ribbon purchased = 20 - 16.16
The cost of the ribbon purchased = $3.84

The price of the ribbon was 24 cents per yard.,
Now yard of ribbon Kira purchased = 3.84 / 0.24 = 16 yards

Thus, Kira bought 16 yards of the ribbon, as of the given conditions.

Answer: The base is 4.8 sq inches.

Step-by-step explanation: The formula for a triangle is (B x H) x 1/2. Knowing this, we can double 8.64 to nullify the 1/2. This gives us 17.28. 17.28 divided by 3.6 gives us 4.8

Answer:

4.8

Step-by-step explanation:

The area of a triangle is half the base times the height.

\(0.5*b*3.6=8.64 \\ b = \frac{8.64}{0.5*3.6}\)

The length of the hypotenuse is approximately 6.802 units and the length of the adjacent side is approximately 5.5 units in the right triangle where one angle measures 36 degrees and its opposite side measures 4 units.

To find the sides of a right triangle where one angle measures 36 degrees and its opposite side measures 4 units, we can use trigonometric ratios.

Let's label the sides of the triangle:
- The side opposite the angle of 36 degrees is called the opposite side and has a length of 4 units.
- The side adjacent to the angle of 36 degrees is called the adjacent side.
- The hypotenuse is the longest side of the right triangle and is opposite the right angle.

Using the trigonometric ratio for the sine function, we can find the length of the hypotenuse:

sin(angle) = opposite / hypotenuse

Plugging in the values we know:

sin(36 degrees) = 4 / hypotenuse

Now, we can solve for the hypotenuse by isolating it:

hypotenuse = 4 / sin(36 degrees)

Using a calculator, we find that sin(36 degrees) is approximately 0.5878.

hypotenuse ≈ 4 / 0.5878 ≈ 6.802

So, the length of the hypotenuse is approximately 6.802 units.

To find the length of the adjacent side, we can use the Pythagorean theorem:

adjacent^2 + opposite^2 = hypotenuse^2

Plugging in the values we know:

adjacent^2 + 4^2 = 6.802^2

Simplifying the equation:

adjacent^2 + 16 = 46.2496

Subtracting 16 from both sides:

adjacent^2 = 30.2496

Taking the square root of both sides:

adjacent ≈ √30.2496 ≈ 5.5

So, the length of the adjacent side is approximately 5.5 units.

In summary, the length of the hypotenuse is approximately 6.802 units and the length of the adjacent side is approximately 5.5 units in the right triangle where one angle measures 36 degrees and its opposite side measures 4 units.

The values of a and b for the function f(x) = (4x+b)/(ax+7) to have x=5 as a vertical asymptote and y=6 as a horizontal asymptote are a=1/6 and b=24.

For the function to have x=5 as a vertical asymptote, the denominator ax+7 must approach 0 as x approaches 5. This means that a must be equal to 1/6 to make ax+7 equal to 0 when x=5.

For the function to have y=6 as a horizontal asymptote, the limit of f(x) as x approaches infinity should be equal to 6. Therefore, we can use the fact that f(x) approaches b/a as x approaches infinity.

If we set b/a = 6, we can solve for b to get b = 6a.

Substituting the value of a we found earlier, we get b = 4.

Therefore, the values of a and b that satisfy the conditions are a=1/6 and b=24.

Answer:

18,25

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

We know that ∠ 1 + ∠ 2 + ∠3 = 180 → (1)

and ∠ 3 + ∠ 4 = 180 → (2)

From (2) ∠ 3 = 180 - ∠ 4

Substitute ∠ 3 = 180 - ∠ 4 into (1)

∠ 1 + ∠ 2 + 180 - ∠ 4 = 180 ( add ∠ 4 to both sides )

∠ 1 + ∠ 2 + 180 = 180 + ∠ 4 ( subtract 180 from both sides )

∠ 1 + ∠ 2 = ∠ 4 → C

The value of the a_5 is -405 if the a_1 =5 and a_n=-3a_{n-1} which is a geometric sequence with common ratio -3.

It is defined as the systematic way of representing the data that follows a certain rule of arithmetic.

We have:

\(\rm a_1 = 5\\\\\rm a_n = -3a_{n-1}\)

Plug n = 2

\(\rm a_2 = -3a_{2-1}\\\\\rm a_2 =- 3a_{1}\\\\a_2 = -15\)(as,  \(\rm a_1 = 5\))

Plug n = 3 we get:

\(a_3 = -45\)

Plug n = 4, we get:

\(\rm a_4 =- 135\)

Now plug n = 5, we get:

Step-by-step explanation:

3a: if you divide the y by the x, you'd get 75 everytime, meaning it's proportional.

3b: y would equal the amount of inches multiplied by 75, so y=75x

3c: you can use the equation and substitute the x for 8, so y=75(8), giving you 600 miles

3d: you can also use the equation in reverse, if the actual miles is 750, then this is your y, so it would look like 750=75x and to solve you'd divide, 750/75, giving you 10 inches

The parametric equations for the motion of the particle in the xy plane that traces the counterclockwise ellipse are x = 6cos(t) and y = 4sin(t), where t is the parameter. The parameter interval for the motion is 0 ≤ t ≤ 2π.

To find the parametric equations for the counterclockwise motion of the particle along the given ellipse, we can start by parameterizing the ellipse equation  \(16x^2 + 9y^2 =\) 144. We divide both sides of the equation by 144 to normalize it, giving us  \((x^2/9) + (y^2/16\)) = 1. By comparing this equation with the standard form of an ellipse, we can see that a = 3 and b = 4.

We can then use the trigonometric parametrization of an ellipse to obtain the parametric equations. Letting x = acos(t) and y = bsin(t), where t is the parameter, we substitute the values for a and b, resulting in x = 6cos(t) and y = 4sin(t). These equations represent the motion of the particle along the ellipse.

Since we want the particle to trace the ellipse counterclockwise, we need to cover the full circumference of the ellipse. This corresponds to a parameter interval of 0 ≤ t ≤ 2π, which completes one full revolution around the unit circle. Therefore, the parametric equations for the motion of the particle are x = 6cos(t) and y = 4sin(t), with a parameter interval of 0 ≤ t ≤ 2π.

Mavis is interested whether military status is related to gender in American Samoa. The data she collected about the population of American Samoa in 2010 is below.

Find the marginal distribution of military status in percentages. Round to the nearest whole percentages.

In Armed Forces:

Military-dependent:

Civilian:

Answer: In Armed Forces: 0%

              Military-dependent: 3%

              Civilian: 97%

Step-by-step explanation: Marginal Distribution is defined as the probability distribution of variables contained in a subset.

For the American Samoa's military status, marginal distribution is

1) In Armed Forces:

\(p_{1}=\frac{87}{55,519}*100\)

\(p_{1}=0.15\)

2) Military-dependent:

\(p_{2}=\frac{1709}{55,519}*100\)

\(p_{2}=3.08\)

3) Civilian:

\(p_{3}=\frac{53,723}{55,519}*100\)

\(p_{3}=96.77\)

Now round each percentage to the nearest whole percentage:

Armed forces: 0%

Military: 3%

Civilian: 97%

The marginal distributions of military status are, in nearest whole percentage:

\(\textsf{For this equation, A, B, and C are integers.}\)

\(\textsf{C is the y-intercept.}\)

\(\textsf{A is the slope.}\)

\(\textsf{B represents how many times the whole equation \underline{was} multiplied by.}\)

\(\underline{\textsf{A more simplified equation;}}\)

\(\tt x + y = c\)

\(\textsf{We need to change this equation into slope-intercept form.}\)

\(\large\underline{\textsf{Slope-Intercept Form;}}\)

\(\tt y = mx+b\)

\(\textsf{Note that this equation \underline{isn't} multiplied.}\)

\(\textsf{M represents the slope.}\)

\(\textsf{B represents the y-intercept.}\)

\(\textsf{We should change where the y is, and divide the equation by how much B is.}\)

\(\large\underline{\textsf{To Start;}}\)

\(\tt-3x+4y=8\)

\(\textsf{The y-intercept is 8.}\)

\(\textsf{The slope is -3.}\)

\(\textsf{The equation is multiplied by 4, so we should divide by 4.}\)

Answer:

y = (3/4)x + 2

Step-by-step explanation:

Now we have to write,

→ The equation in slope-intercept form.

The equation is,

→ -3x + 4y = 8

The slope-intercept form is,

→ y = mx + b

Let's rewrite the given equation,

→ -3x + 4y = 8

→ 4y = 8 + 3x

→ 4y = 3x + 8

→ y = (3x + 8)/4

→ y = (3x/4) + (8/4)

→ [ y = (3/4)x + 2 ]

Hence, the answer is y = (3/4)x + 2.

The solutions in the interval [0, 2π) for the equation sin(2x) - 2cos(x) = 0 are x = π/2 and x = 3π/2.

To find all solutions in the interval [0, 2π) for the equation sin(2x) - 2cos(x) = 0, we can use trigonometric identities to simplify and solve for x.

Let's rewrite the equation using the double-angle identity for sine:

2sin(x)cos(x) - 2cos(x) = 0

Now, we can factor out 2cos(x) from the equation:

2cos(x)(sin(x) - 1) = 0

To find the solutions, we set each factor equal to zero and solve for x:

cos(x) = 0:

In the interval [0, 2π), cos(x) equals zero at x = π/2 and x = 3π/2.

sin(x) - 1 = 0:

Adding 1 to both sides gives sin(x) = 1. In the interval [0, 2π), sin(x) equals one at x = π/2.

Therefore, the solutions in the interval [0, 2π) for the equation sin(2x) - 2cos(x) = 0 are:

x = π/2, 3π/2.

These are the values of x within the specified interval that satisfy the given equation.
