Bobbi owes a total of $10,455.75 in taxes.

Taxes are compulsory financial charges imposed by governments on individuals or entities based on income, property, or goods/services.

To compute the tax owed by Bobbi, we can use the following steps:

Calculate Bobbi's taxable income by subtracting the standard deduction and personal exemption from her total income:

Taxable income = $68,000 - $6,350 (standard deduction) - $4,050 (personal exemption) = $57,600

Determine the tax bracket in which Bobbi's taxable income falls:

Bobbi's taxable income of $57,600 falls in the 25% tax bracket.

Calculate the tax owed by Bobbi by applying the marginal tax rates to her taxable income. We can use the following formula:

Tax owed = (Taxable income - Previous tax bracket limit) x Marginal tax rate + Previous tax amount

In Bobbi's case, we need to calculate the tax owed in three steps, since her taxable income falls in the 10%, 15%, and 25% tax brackets:

For the first $9,325 of her taxable income, Bobbi owes 10% in taxes:

Tax owed = ($9,325 - $0) x 0.10 + $0 = $932.50

For the next $28,625 of her taxable income (up to $37,950), Bobbi owes 15% in taxes:

Tax owed = ($37,950 - $9,325) x 0.15 + $932.50 = $3,825.75

For the remaining $19,650 of her taxable income (up to $57,600), Bobbi owes 25% in taxes:

Tax owed = ($57,600 - $37,950) x 0.25 + $3,825.75 = $5,697.50

Answer:

The y-intercept represents a starting salary of $32,500.

The slope represents an additional $2,500 in salary for each additional year of employment.

If the starting salary for a new employee is changed to $35,000 and the yearly salary increase is unchanged, the new equation would be
[tex]y=2500x+35000[/tex].

If the yearly salary increase is changed to $3,000 and the starting salary remains the same, the new equation would be
[tex]y = 3000x + 32500[/tex].

Step-by-step explanation:

Answer:

The y-intercept represents a starting salary of $32,500.

The slope represents an additional $2,500 in salary for each additional year of employment.

If the starting salary for a new employee is changed to $35,000 and the yearly salary increase is unchanged, the new equation would be

y=2500x+35000y=2500x+35000 .

If the yearly salary increase is changed to $3,000 and the starting salary remains the same, the new equation would be

y = 3000x + 32500y=3000x+32500 .

Step-by-step explanation:

The area of the forest will be approximately 1396 km sq. after 10 years.

Given that, a forest covers an area of 2100 km sq and that each year this area decreases by 4%..

If the area of the forest decreases by 4% each year, then after one year it will be 96% of the original size.

After two years, it will be 96% of 96% of the original size, or 0.96² of the original size.

After ten years, it will be 96% of itself ten times, or 0.96¹⁰ of the original size.

So the area of the forest after 10 years will be:

Area = Initial area × 0.96¹⁰

Area = 2100 km sq × 0.96¹⁰

Area = 1396 km sq

Therefore, the area of the forest cover in 10 years will be 1396 km sq.

To solve this problem, we need to first determine how long it will take for Justin's money to triple in value. We can use the formula for compound interest:

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

where:

A = the final amount

P = the principal (initial amount)

r = the annual interest rate (as a decimal)

n = the number of times the interest is compounded per year

t = the number of years

For Justin, we have:

P = $940

r = 0.07625

n = 12 (monthly compounding)

t = unknown

We want to solve for t when A = 3P = $2820. We can rearrange the formula and plug in the values:

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

3P = P(1 + r/n)^(nt)

3 = (1 + 0.07625/12)^(12t)

ln(3) = 12t * ln(1 + 0.07625/12)

t = ln(3) / (12 * ln(1 + 0.07625/12))

t ≈ 15.8 years

So it will take Justin about 15.8 years for his money to triple in value.

Now we can use the same formula to find how much money Hailey will have in her account after 15.8 years:

P = $940

r = 0.0825

n = 4 (quarterly compounding)

t = 15.8

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

A = $940(1 + 0.0825/4)^(4*15.8)

A ≈ $3501

Therefore, Hailey will have about $3,501 in her account when Justin's money has tripled in value

The number 3 in the equation h(t) = -16t² + 6t+ 3 represents the initial height from which the ball is thrown.

The equation h(t) = -16t² + 6t+ 3 models the height of the ball thrown in the air, with h(t) measured in feet and time, t, measured in seconds. The number 3 in this equation refers to the height from which the ball is thrown. This is represented by the constant term 3, which is added to the equation after the sum of the variables. The formula h(t) = -16t² + 6t+ 3 can be broken down into three parts. The first part is the constant term, 3, which denotes the initial height of the ball. The second part is the linear term, 6t, which represents the acceleration of the ball due to gravity. Lastly, the quadratic term, -16t², is used to describe the rate at which the ball’s acceleration slows down due to air resistance. Therefore the number 3 in the equation h(t) = -16t² + 6t+ 3 represents the initial height from which the ball is thrown.

Ok so basically, what I would do is make note of each of the points of the triangle, and them multiply them by four, or the scale factor.

The linear equation that can be given for squirrel y is the value of 12x.

According to the question,

Animal            Mouse       Squirrel

Speed(mph)         8                12

SInce "x" the time goes along with x-axis and "y" is  the distance covered by the animal.

The mouse time and distance would plot the graph (1,8)(2,16)(3,24)....

The squirrel time and distance would plot the graph (1,12)(2,24)(3,36)....

Let us consider the track is a straight line and the shorter distance is 50 meters.

The formula for straight line equation y = mx + b  where 'b' is the base value, 'x' is the time and 'y' is the distance.

The linear equation for squirrel y = 12x+b and the squirrel starts at 0 meters per hour. so the equation becomes y = 12x.

The linear equation for mouse y = 8x + b  and the mouse starts at 0 meters.  so the equation becomes y = 8x.

Distance covered by the mouse and the squirrel at time x = 3 we can find the distance covered by the mouse and the squirrel.

y =12x

y = 12(3)

y = 36.

The distance covered by the squirrel is 36km at time 3hours.

For mouse, at time x = 3 hours.

y = 8(3)

y=24.

The distance covered by the squirrel is 24km at time 3hours.

Hence, The linear equation for squirrel y = 12x.

The linear equation for mouse  y = 8x

The distance covered by the squirrel is 36km at time 3hours.

The distance covered by the squirrel is 24km at time 3hours.

Answer:

None of it.

Step-by-step explanation:

Notice the slope is 2.75 this means for EVERY X the graph goes up by 2.75 in the Y axis. For example.
If at                 X=1     y=0
Then for         X=2   y=2.75

and for            X=3  y=2.75+2.75=5.5
also the graph must pass thought point (0,0), the origin, and none of the graph follow this.  

You can also compare the slopes of each equations
for graph A, from x=1 to x=2 the height Y goes from 3 to 3.5, this is a slope of 0.5 (not the 2.75 we are looking for)

for graph A, from x=1 to x=2 the height Y goes from 1 to 2.5, this is a slope of 1.5 (not the 2.75 we are looking for)

for graph A, from x=1 to x=2 the height Y goes from 1 to 2.75 this is a slope of 1.75 (not the 2.75 we are looking for)

notice the last is similar to equation y=1.75X+b, just in case.

Total distance = 3 1/2 miles

Covered distance = 2 3/4 miles

To make things easier let's convert our parameters from fraction to decimal,

Therefore,

Total distance= 3.5 miles

Covered distance = 2.75 miles

Remaining distance = Total distance - Covered distance

Remaining distance = 3.5 miles - 2.75 miles

Remaining distance= 0.75 miles

Converting back to fraction,

Remaining distance = 3/4 miles

Step-by-step explanation:

law of cosine

c² = a² + b² - 2ab×cos(C)

c is the side opposite of the C angle. a and b are the other 2 sides.

AB² = 4² + 4² = 16 + 16 = 32

AB = c = sqrt(32) = 5.656854249...

since a and b are equal (isoceles triangle), so must be the angles at A and B.

the sum of all angles in a triangle is always 180°.

180 = angle A + angle B + angle C

= angle A + angle B + 120

since angle A = angle B we get

180 = 2×angle A + 120

2×angle A = 60°

angle A = angle B = 30°.
