Sara calculated the unit rate as dollars per orange whereas Sara's friend Daniel calculated unit rate as oranges per dollar.

What is unit rate?

One of a given object constitutes a unit. The cost of only one of an item is its unit rate. With one as the denominator, this is written as a ratio. For instance, you would move 7 yards on average every second if you covered 70 yards in 10 seconds.

Sara said there was a ratio of 12 to 8, so the unit rate was $1.50 per orange, it means she is calculating the unit rate as dollar per oranges.

Whereas, his friend Daniel, he thought the ratio would be 8:12, so the unit rate would be 8/12 oranges per dollar.

In this way both the unit rates are correct.

1. ≈ 33759 bees

The parent function for exponential functions is y = a(b^x), where "a" is the initial value and "b" is the growth rate. In this case, "x" is the number of days, and "y" is the number of bees after "x" days. We already know that the initial value is 20, so we can set "a = 20". Next, we know that after 5 days, there are 29 bees, which we can also plug into our equation: "x = 5" and "y = 29". Then, we end up with the equation 29=20(b^5) and solve for the growth rate, "b". To solve for "b", first divide both sides by 20, and then take the 5th root of both sides:

29 = 20(b^5)

29/20 = b^5

^5√(29/20) = ^5√(b^5)

^5√(29/20) = b

Now, we know the equation to this problem is y = 20((^5√(29/20))^x). We can plug in "x = 100" to find the number of bees after 100 days.

y = 20((^5√(29/20))^100)

y ≈ 33759 bees

2. No, you can't find the inverse of the function y=4x^2 + 12x + 9, because, for an inverse to be possible, it must pass the horizontal line test, which this function does not pass. The domain restriction necessary would have to make it so the function passes the horizontal line test, which would mean restricting half of the function from its vertex in this case. The x-value of the vertex (refer to the vertex formula) of this function is -12/8, so we can restrict the domain by only letting the domain be [-12/8, +infinity). Finding the inverse (switch "x" and "y", and solve for "y"):

x = 4y^2 + 12y + 9                                x:  [-12/8, +infinity)

x - 9 = 4y^2 + 12y

x - 9 = 4y^2 + 12y

(x - 9)/4 = y^2 + 3y

(x - 9)/4 + 2.25 = y^2 + 3y + 2.25

(x - 9)/4 + 2.25 = (y + 1.5)^2

√((x - 9)/4 + 2.25) = y + 1.5

√((x - 9 + 9)/4) = y + 1.5

(√(x) / 2) - 1.5 = y

(-3 + √(x))/2 = y

3a. To solve this problem, we have to find a way to use "log base5 of 3" and "log base5 of 8" to get "log base5 of 2".

First, we can exclude the logbase5 so the problem is easier to look at. We need to find a way to get "2" using "3" and/or "8" (cannot use subtraction/addition in this step, and using "3" and/or "8" is required with multiplication/division). Keep in mind the rules of logs with the same base.

8^1/3 = 2

Now, we put the logbase5 back in:

logbase5 of (8^1/3) = logbase5 of 2

From log rules, we can move the exponent "1/3" down:

1/3 * logbase5 of 8

We know that logbase5 of 8 = 1.2920

1/3 * 1.2920

approximately 0.4307

3b. As previously explained, we need to use "3" and "8" to get to "75/8" while keeping in mind the rules of logs.

First, we can simplify "logbase5 of (75/8)":

logbase5 of (75/8) = (logbase5 of 75) - (logbase5 of 8)

Now, ignore the "logbase5" and use provided values of "3" and "8" to get to 75. Note that we can use the number 5: logbasex of x= 1 [x^1 = x]

(5^2) * 3 = 75

Next, place the "logbase5" back in, and simplify

logbase5 of ((5^2) * 3) - logbase5 of 8

logbase5 of (5^2) + logbase5 of 3 - logbase5 of 8

2logbase5 of 5 + logbase5 of 3 - logbase5 of 8

2(1) + 0.6826 - 1.2920

approximately 1.3906

A deferred tax liability can arise when the tax return and the income statement report a revenue or expense in different years

A deferred tax liability is a balance-sheet entry that records taxes that are owed but are not due to be paid until a later date. The liability is postponed due to a timing difference between when the tax was accrued and when it is due to be paid.

On the balance sheet, deferred income tax appears as a liability. The most common cause of deferred income tax is a discrepancy between the IRS and GAAP depreciation methods. Income tax deferral can be classified as either a current or long-term liability.

The coordinates of point P along QR so that the ratio of QP to PR is 1 to 4 is P(6,3).

It is the comparison of one quantity with another. For example, if your weight is 30 kg and your father's weight is 90 kg, then the ratio of weight is 1:3.

Given:

The coordinates of Q = (8,4),

The coordinates of R = (-2, -1),

The ratio of QP/PR = 1/4,

Calculate the coordinates of the P by the following formula,

P(x, y) = [(mx₂ + nx₁) / m + n , (my₂ + ny₁ ) / m + n]

Here m and n are ratio and m/n = 1/4

Substitute the values,

P(x, y) = [1 × (-2) + 4 × 8] / 1 + 4 , [1 × (-1) + 4 × 4] / 1 + 4

P(x, y) = (6,3)

The maximum value of the quadratic function F(x) = -3x² + 18x + 3 is 30 when x = 3

The quadratic equation is given as

F(x) = -3x² + 18x + 3

The above function is a quadratic function

As a general rule, a quadratic function has the following representation:

F(x) = ax² + bx + 3

This means that: a = -3

The value of a for a quadratic function must be less than 0 for the function to have a maximum

This means that the function has a maximum value because -3 is less than 0

Solving further, we have

F(x) = -3x² + 18x + 3

Differentiate and set to 0

-6x + 18 = 0

So, we have

x = 3

Substitute x = 3 in F(x)

F(3) = -3(3)² + 18(3) + 3

Evaluate

F(3) = 30

This represents the maximum value

The measurement of ∠1 =  136° and ∠2 = x = 44°, using Vertically opposed angles.

What is Vertically opposed angles?

Two lines intersecting at a point create vertical angles. Every time they are on an equal footing. Alternatively stated, four angles are created anytime two lines cross or intersect. Two opposed angles are equal and are referred to as vertical angles, as we can see. Due to their position opposite one another, they are also known as "Vertically opposed angles."

Angles that are vertically opposed to one another at a certain vertex are formed by two straight lines intersecting. The equality of the vertically opposed angles has been established.

∠x = 44

∠2 = x = 44

∠1 + ∠2 = 180

∠1 = 180 - 44 = 136°

Where, ''an'' be the construction worker's salary in the nth year.

B) The value of a₁₀ = $54,000

C) After 11 years her salary will be $55,100.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

A construction worker's starting salary = $43,000.

And, Each year she receives a $1100 raise.

Now,

A) Let ''an'' be the construction worker's salary in the nth year.

So, We can formulate;

⇒ an = $43,000 + $1,100n

B) Since, The construction worker's salary in the nth year is,

⇒ an = $43,000 + $1,100n

Put n = 10, we get;

⇒ a₁₀ = $43,000 + $1,100 × 10

⇒ a₁₀ = $43,000 + $11,000

⇒ a₁₀ = $54,000

C) Let after n year her salary will be $55,100.

So, We can formulate;

⇒ an = $43,000 + $1,100n

⇒ $55,100 = $43,000 + $1,100n

Solve for n as;

⇒ $55,100 - $43,000 = $1,100n

⇒ $12,100 = $1,100n

⇒ n = 12,100 / 1,100

⇒ n = 11

Thus, After 11 years her salary will be $55,100.

Therefore, A) The explicit formula which model this situation will be;

⇒ an = $43,000 + $1,100n

Where, ''an'' be the construction worker's salary in the nth year.

B) The value of a₁₀ = $54,000
