a. the principal (loan amount) is $5000, the rate is 8.25%, and the time is 9 months (expressed in years as 9/12). b. the student will have to pay $306.25 in interest, and the future value of the loan will be $5306.25.

a. The student must pay $306.25 in interest.

To calculate the amount of interest, we can use the formula for simple interest:

Interest = Principal × Rate × Time

In this case, the principal (loan amount) is $5000, the rate is 8.25%, and the time is 9 months (expressed in years as 9/12).

Plugging in these values into the formula, we can calculate the interest amount the student must pay.

b. The future value of the loan is $5306.25.

To find the future value, we add the interest amount to the principal amount.

The future value is calculated using the formula:

Future Value = Principal + Interest

By substituting the values of the principal ($5000) and the interest ($306.25), we can find the future value of the loan.

Therefore, the student will have to pay $306.25 in interest, and the future value of the loan will be $5306.25.

y-5=3(x- (-9)

Step-by-step explanation:

Thus,  x-3 is not a factor if 2x³ - 5x² - 5x + 11. To make it the factor subtract 5 from the dividend.

A polynomial is factored when it is expressed as the product with two or more factors; this is somewhat the opposite of multiplying.

One of a single-variable polynomial's linear expressions is referred to as a factor. Many variables can affect a polynomial,

Given word problem.

2x cubed minus 5x squared minus 5x plus 11

This can be written as:

2x³ - 5x² - 5x + 11

So,

dividend : 2x³ - 5x² - 5x + 11

divisor =  x-3 , x = 3

Put x = 3 in dividend , if it comes zero, it is the factor.

= 2x³ - 5x² - 5x + 11

= 2(3)³ - 5(3)² - 5(3) + 11

= 5 (remainder)

Thus,  x-3 is not a factor if 2x³ - 5x² - 5x + 11. To make it the factor subtract 5 from the dividend.

The changes in the volume of the spherical balloon is approximately o.3351-meter cube.

the volume of the sphere =\(v=\frac{4}{3}\pi r^3\)

using the definition of differential to find the change we write

                                          \(dv=\frac{4}{3}\pi (dr)^3\)

where,                               \(dr\)=\(r_{2}-r_{2}\)

                                         \(dr\)=\(2-1.8\\\)

                                         \(dr\) \(=0.2\)

                                         \(dv=\frac{4}{3}\pi (0.2)^3\)

                                         \(dv=0.3351\) approx.

where dr and dv represent the differential or change with respect to radius and volume in the above calculation. so first we apply differential on both sides of the formula of the sphere then we find its approximation by the next coming equation. so, the volume of the sphere is approximately 0.3351-meter cube here approximation represents that it is not the exact solution it is basically approximated solution.

Answer:

3.2 π

Step-by-step explanation:

The volume V of a sphere with radius r is given by the formula V = (4/3) * π * r^3.

Taking the derivative with respect to r, we get dV/dr = 4 * π * r^2.

Let dr be the change in radius, which is 1.8 - 2 = -0.2.

The differential dV is given by dV ≈ (dV/dr) * dr = 4 * π * r^2 * dr.

Substituting r = 2 and dr = -0.2, we get dV ≈ 4 * π * 2^2 * (-0.2) = -3.2 * π.

So, using differentials, we estimate that the volume of the balloon decreases by approximately 3.2 * π cubic meters as it deflates from a radius of 2 meters to a radius of 1.8 meters.

The formula for the volume of a cone is:

V = (1/3)πr²h

where r is the radius of the base, h is the height of the cone, and π is pi.

In this case, the slant height is given as 17 cm, which we can use with the radius to find the height of the cone using the Pythagorean theorem:

h² = s² - r²

h² = 17² - 8²

h² = 225

h = 15

Now that we have the height, we can plug in the values for r and h into the formula for the volume:

V = (1/3)π(8²)(15)

V = (1/3)π(64)(15)

V = (1/3)(960π)

V = 320π

Therefore, the volume of the cone is 320π cubic cm. Answer: 320π.

Answer:

El incremento total con respecto al precio inicial es de 32% y Rosa tiene razón con respecto al porcentaje (no se incrementó 35%).

En cuanto al dinero que les sobra, ninguno de ellos está en lo correcto pues les sobran 12 soles.

Step-by-step explanation:

En un principio, la caja de herramientas costaba 180 soles.

Después de una semana el precio se incrementó 10%, el 10% de 180 soles es 18 por lo que la caja costaba 180 + 18 = 198 soles.

Ellos volvieron la siguiente semana y vieron que el precio se había incrementado un 20% con respecto a la semana anterior, el 20% de 198 es igual a 198 x 0.20 = 39.6 por lo que el precio ahora era de 198 + 39.6 = 237.6 soles.

Para saber el incremento total con respecto al precio inicial podemos hacer una proporción:

180 soles : 100

237.6 soles : x

Despejando x tenemos que:

\(x= \frac{237.6(100)}{180}=\frac{23760}{180}=132\)

Por lo tanto, el incremento total con respecto al precio inicial es de 32% y Rosa tiene razón con respecto al porcentaje (no se incrementó 35%)

Sin embargo, ellos cuentan con 250 soles y la caja cuesta 237.6 ≈238 soles, por lo tanto, les alcanza y les sobran 250 - 238 = 12 soles.

The answer to two decimal places would be 7.98 feet, so we don't need to round further.

How to solve a  circle?

To find the diameter of a circle given its circumference, we can use the formula:

Circumference = π × Diameter

where π is the mathematical constant pi (approximately 3.14).

In this problem, we are given that the circumference of the circle is 25.12 feet. So we can plug that value into the formula:

25.12 = 3.14 × Diameter

To solve for the diameter, we need to isolate the variable (Diameter) on one side of the equation. We can do this by dividing both sides of the equation by 3.14:

25.12 ÷ 3.14 = Diameter

This gives us:

Diameter = 7.98 feet

Therefore, the diameter of the circle is approximately 7.98 feet.

It's worth noting that since the problem statement only gives π to two decimal places, we should round our answer to the same level of precision. The answer to two decimal places would be 7.98 feet, so we don't need to round further.

The percentage of the total mattresses that are not extra firm non-memory foam mattresses is 17%.

Let's break down the information step by step to find the percentage of the total mattresses that are not extra firm non-memory foam mattresses.

Let:

M = Total number of mattresses

MF = Memory foam mattresses

EF = Extra firm mattresses

MF&EF = Memory foam and extra firm mattresses (extra firm memory foam mattresses)

From the given information, we have:

1. 75% of the mattresses are memory foam: MF = 0.75 * M

2. 20% of the mattresses are extra firm: EF = 0.20 * M

3. 12% of the total mattresses are extra firm memory foam: MF&EF = 0.12 * M

Now, to find the percentage of mattresses that are not extra firm non-memory foam, we need to subtract the number of memory foam, extra firm, and extra firm memory foam mattresses from the total number of mattresses:

Not extra firm non-memory foam mattresses = M - (MF + EF - MF&EF)

Plugging in the values:

Not extra firm non-memory foam mattresses = M - (0.75 * M + 0.20 * M - 0.12 * M)

Not extra firm non-memory foam mattresses = M - (0.83 * M)

Now, the percentage of not extra firm non-memory foam mattresses is:

Percentage = (Not extra firm non-memory foam mattresses / M) * 100

Percentage = ((M - 0.83 * M) / M) * 100

Percentage = (0.17 * M / M) * 100

Percentage = 0.17 * 100

Percentage = 17%

So, the percentage of the total mattresses that are not extra firm non-memory foam mattresses is 17%.

The correct option is F. 17.
