Answer:

Step-by-step explanation:

To find the annual tax withheld, you would need to calculate the amount of income tax that you owe based on your income and the state income tax rate.

You earn $56,000 per year and the state income tax rate is 5.5%. To find the amount of tax you owe, you would multiply your income by the tax rate.

Tax Owed = Income x Tax Rate

Tax Owed = 56,000 x 0.055

Tax Owed = 3,080

So, the annual tax withheld from your salary would be $3,080.

Answer:

The tablecloth overhang is the amount of tablecloth that hangs over the edges of the table.

The area of the square table is 1.3m * 1.3m = 1.69m^2.

The area of the round tablecloth is pi * (diameter/2)^2 = pi * (2/2)^2 = pi * 1^2 = pi * 1 = pi m^2.

The overhang is the difference between the area of the round tablecloth and the square table.

Overhang = pi m^2 - 1.69m^2 = pi - 1.69

To find the percentage of the tablecloth that overhangs the table, we can divide the overhang by the area of the tablecloth and multiply by 100.

Overhang % = (pi - 1.69) / pi * 100 = (pi - 1.69) / pi * 100 = (3.14 - 1.69) / 3.14 * 100 = 1.45 / 3.14 * 100 = 46.14%.

So, the percentage of the tablecloth that overhangs the table is 46.14%.

The probability of getting a difference of 3 when two fair dice are thrown together is 1/9.

Probability is the measure of how likely it is that a certain event will occur. It is expressed as a number between 0 and 1, where 0 indicates that an event is impossible and 1 indicates that an event is certain. Probability can also be expressed as a percentage or fraction. Probability is used to describe the likelihood of an event occurring, and its calculation is based on the number of possible outcomes of the event.

This is due to the fact that there are 6 possible outcomes for each dice, and 36 possible outcomes when both dice are thrown. The only way to get a difference of 3 is for the first dice to show a 4 (1/6 probability) and the second dice to show a 1 (also 1/6 probability). This gives a combined probability of 1/6 x 1/6 = 1/36, which is 1/9.

According to the power of a point.

[tex]QP^{2}[/tex]  =  QR*QT

[tex]6^{2}[/tex]  =  3*QT

QT = 12

Since QR = 3, RT = 9.

Since RS = 3, ST = 6.

Draw OT and OR, creating a triangle(TSO) and triangle(RSO).

OT and OR are radii, Let the radius be r.

Use the Law of Cosines on these two triangles.

OT2  =  [tex]r^{2}[/tex]  =  [tex]6^{2}[/tex] + [tex]2^{2}[/tex] - 2*6*2*cos(TSO)

OR2  =  r2  =  [tex]3^{2}[/tex] + [tex]2^{2}[/tex] - 2*3*2*cos(RSO)

Since these are equal:

[tex]6^{2}[/tex] + [tex]2^{2}[/tex] - 2*6*2*cos(TSO)  =  [tex]3^{2}[/tex] + [tex]2^{2}[/tex] - 2*3*2*cos(RSO)

40 - 24*cos(TSO)  =  13 - 12*cos(RSO)

Since angle(RSO) is supplementary to angle(TSO),  cos(RSO) = - cos(TSO)

40 - 24*cos(TSO)  =  13 + 12*cos(TSO)

27  =  36*cos(TSO)

0.75  =  cos(TSO)

Since  [tex]OT^{2}[/tex]  =  [tex]r^{2}[/tex]  =  [tex]6^{2}[/tex] + [tex]2^{2}[/tex] - 2*6*2*cos(TSO)

[tex]r^{2}[/tex]  =  40 - 24*0.75

The average speed of the bus is 54.78 mph.

To find the average speed of the bus, we need to find the total distance traveled and the total time taken for the entire trip.

Distance traveled = 10 miles + 17 miles + 95 miles + 4 miles = 126 miles

To find the total time taken, we need to calculate the time taken for each segment of the trip and add them up.

Time taken for 10 miles at 25 mi/h = 10 miles / 25 mi/h = 0.4 hours

Time taken for 17 miles at 45 mi/h = 17 miles / 45 mi/h = 0.378 hours

Time taken for 95 miles at 80 mi/h = 95 miles / 80 mi/h = 1.1875 hours

Time taken for 4 miles at 12 mi/h = 4 miles / 12 mi/h = 0.333 hours

Total time taken = 0.4 hours + 0.378 hours + 1.1875 hours + 0.333 hours = 2.3 hours

Average speed = total distance / total time = 126 miles / 2.3 hours = 54.78 mph

The surface area of the ice is 16π square inches. At a rate of 10 cubic inches per min, the outer surface area of the ice is changing at  10/16π square inches per min.

To calculate this we have given:

The diameter of the spherical ball is 8 inches, so the radius of the ball is 8/2 = 4 inches.

The volume of a sphere is given by the formula (4/3)πr³, where r is the radius of the sphere.

The volume of the spherical ball with 2 inches of ice is (4/3)π(4³) = (4/3)π64 cubic inches.

The volume of the ice is the volume of the spherical ball with 2 inches of ice minus the volume of the spherical ball without the ice, which is (4/3)π(4³) - (4/3)π(4³ - (2³)) = (4/3)π64 - (4/3)π32 = 32π cubic inches

At a rate of 10 cubic inches per min, the thickness of the ice is decreasing at:

10 cubic inches / 32π cubic inches = 10/32π inches per min

To find the rate at which the outer surface area of the ice is changing, we can use the formula for the surface area of a sphere which is 4πr².

The surface area of the ice is 4π(4-2)³ = 4π4 = 16π square inches.

The anti-derivative of g(x) is G(x) = x3 + 3x2 and the anti-derivative of f(x) is F(x) = x2 + 2x.

Part a:

The value of the integral from 0 to 6 of f(x)dx is 16. This can be calculated using the Fundamental Theorem of Calculus (FTC) which states that the integral of a function is equal to the anti-derivative of that function evaluated at the upper limit minus the anti-derivative of that function evaluated at the lower limit. This can be written as:

∫f(x)dx = F(6) - F(0)

The anti-derivative of f(x) is F(x) = x2 + 2x, so the value of the integral is:

∫f(x)dx = (62 + 2*6) - (02 + 2*0) = 36 - 0 = 16.

Part b:

The value of the integral from 4 to 9 of g(x)dx is 20. This can be calculated using the FTC which states that the integral of a function is equal to the anti-derivative of that function evaluated at the upper limit minus the anti-derivative of that function evaluated at the lower limit. This can be written as:

∫g(x)dx = G(9) - G(4)

The anti-derivative of g(x) is G(x) = x3 + 3x2, so the value of the integral is:

∫g(x)dx = (93 + 3*9) - (43 + 3*4) = 729 - 168 = 20.

Part c:

The value of the integral from 4 to 9 of 2*g(x) - f(x)dx is 68. This can be calculated using the FTC which states that the integral of a function is equal to the anti-derivative of that function evaluated at the upper limit minus the anti-derivative of that function evaluated at the lower limit. This can be written as:

∫(2*g(x) - f(x))dx = 2*G(9) - F(9) - [2*G(4) - F(4)]

The anti-derivative of g(x) is G(x) = x3 + 3x2 and the anti-derivative of f(x) is F(x) = x2 + 2x, so the value of the integral is:

∫(2*g(x) - f(x))dx = (2*(93 + 3*9) - (92 + 2*9)) - [2*(43 + 3*4) - (42 + 2*4)]

= (1854 - 19) - (544 - 16) = 1735 - 528 = 68.
