Oliver is buying a new dishwasher. The dishwasher’s price is $285.10 after tax. He has a few payment options. He can put it on his debit card, which would take the money from his savings account. His savings account earns interest at a rate of 1.8% annually. He could also put it on one of two different credit cards. Card A has an annual interest rate of 9%, charged monthly, and charges a flat 1.2% fee on the initial value of the purchase (note: the fee accrues interest too). Card B has an annual interest rate of 12%, charged monthly, but no fee for purchases. Oliver thinks it will take five months for him to earn the additional money to offset the purchase. In all cases, the interest accrues according to this equation:

A = P(1 + r)n, where A is the final dollar amount, P is the principal (initial amount borrowed), r is the interest rate for each interest period, and n is the number of interest periods.

The distance that the ball has traveled when the height of the ball is 80 feet is either about 9.86 feet or about 3.64 feet.

We are given that;

Velocity= 140feet

Inclination= 45degrees

Function  ​h(x)=(-32x^2/140^2)+x

Now,

To find the distance that the ball has traveled when the height of the ball is 80 feet, we need to solve the equation:

h(x) = 80

Substituting h(x) with the given function, we get:

(-32x2/1402) + x = 80

Multiplying both sides by 140^2 and simplifying, we get:

-32x^2 + 140x - 11200 = 0

Dividing both sides by -32 and simplifying, we get:

x^2 - (35/4)x + 350 = 0

Using the quadratic formula, we get:

x = [ (35/4) ± √( (35/4)^2 - 4(350) ) ] / 2 x ≈ 9.86 or x ≈ 3.64

Using a graphing utility, we can confirm that these are the approximate x-intercepts of the function h(x) - 80.

Therefore, by graphing the answer will be about 9.86 feet or about 3.64 feet.

The total number of zero pairs in the expression (-5) + (-8) is 2.

We must pair the negative numbers so that their sum is equal to zero in order to determine the number of zero pairs in this expression. To put it another way, we need to find pairs of numbers whose sum is the same as their additive inverse.

We are combining two negative numbers in the expression (-5) + (-8).

In this case, we can pair the (-5) with a (+5), since (-5) + (+5) = 0, and we can also pair the (-8) with a (+8), since (-8) + (+8) = 0.

As a result, the expression (-5) + (-8) contains two zero pairs: one for (-5) and (+5) and one for (-8) and (+8).

X + 1 = 0, so x = -1, and x - 24 = 0, so x = 24. Consequently, the two answers to the equation are x = -1 and x = 24.

It is a method for illustrating a notion, a connection, or a behaviour that often involves two or more variables. Equations can be used to explain several events, including economic models and physical principles. They can also be applied to problem-solving and forecasting. Symbols, integers, and mathematical operations like addition, subtraction, multiplication, and division are used to create equations.

An essential tool for factoring quadratic equations is the Zero Factor Property. Finding two terms, one of which is a factor of the constant term and the other of which is a factor of the coefficient of the squared term, whose product is equal to the constant term, is the fundamental principle behind the Zero Factor Property. With this knowledge, the given quadratic equation can be factored into two parts that equal zero.

One must first factor a quadratic equation into two factors that are equal to zero in order to solve it using the zero factor property. To do this, one needs determine the constant term's factors as well as the coefficient of the squared term's factors. The coefficient of the squared term is always obtained by multiplying the factors, which are always different integers.

The constant term's factors are always sums of numbers that result in the constant term. Once the elements are known, the equation can be factored into two factors that are equal to zero each.

Consider the equation [tex]x^2+5x-24=0[/tex], for instance. The factors of the constant term are -1 and 24, while the factors of the squared term's coefficient are 1 and 5. The equation then reads as (x + 1)(x - 24) = 0.

At this stage, the Zero Factor Property can be used to find x. Since all factors must be equal to zero, x can be solved for by setting all factors to zero. Thus, x + 1 = 0, resulting in x = -1, and x – 24 = 0, resulting in x = 24. Thus, x = -1 and x = 24 are the two answers to the problem.

The machine's book value at the end of year three is $164,000.

The total amount of hours used by the machine in the first three years is: 2,000 + 4,000 + 8,000 = 14,000 hours

To calculate the annual depreciation expense, we must first establish the depreciation rate per machine hour. The following is how the depreciation rate per machine hour is calculated:

Depreciation rate per machine hour = (machine cost - estimated residual value) / total number of machine hours estimated

Rate of depreciation per machine hour = ($500,000 - $20,000) / 20,000 machine hours

Depreciation per machine hour = $480,000 divided by 20,000 machine hours

Rate of depreciation per machine hour = $24 per machine hour

We may compute the depreciation expense for each year by using the depreciation rate per machine hour:

Depreciation expense in year one = depreciation rate per machine hour x hours used in the first year

Depreciation expense in year one = $24 x 2,000 hours

Depreciation expense for the first year = $48,000

Year 2 depreciation expense = Depreciation rate per machine hour multiplied by the number of hours consumed in year 2.

Depreciation expense for year 2 = $24 x 4,000 hours

Depreciation expense for year two = $96,000

Depreciation expense in year three = depreciation rate per machine hour x hours used in year three

Depreciation expense in year three = $24 x 8,000 hours

Depreciation expense during the third year = $192,000

The accumulated depreciation for the first three years is the sum of the following depreciation expenses:

Accumulated depreciation equals the sum of year one depreciation expense, year two depreciation expense, and year three depreciation expense.

Depreciation accumulated = $48,000 + $96,000 + $192,000

Depreciation accumulated = $336,000

To compute the machine's book value at the end of the year 3. We deduct the accumulated depreciation from the machine's cost:

Machine book value = machine cost minus accumulated depreciation

The machine's book value is $500,000 minus $336,000

The machine's book value is $164,000

As a result, the machine's book value at the end of year three is $164,000.

What is a y-intercept?

A function or relationship's graph meets the y-axis of the coordinate system at a point known as a y-intercept, sometimes known as a vertical intercept.

The equation of the tangent line to the graph of y = g(x) at x = 2 is y = 6x - 17.

The point-slope form of the equation of a line can be used to find the equation of the tangent line to the graph of y = g(x) at x = 2.

y - y1 = m(x - x1)

where m is the tangent line's slope and (x1, y1) is the point on the g(x) graph at x = 2.

Given that g(2) = -5, the point on the g(x) graph at x = 2 is (2, -5).

We are told that g'(2) = 6, which is the slope of the tangent line at x = 2.

As a result, the tangent line equation is: y - (-5) = 6(x - 2)

We get the following after simplifying and rearranging:

y + 5 = 6x - 12 y = 6x - 17

Answer:

-tan(x)/sin^2(x).

Step-by-step explanation:

To simplify the expression:

sec(x)sin(-x) + tan(-x)

1 + sec(-x)

We can use the fact that sin(-x) = -sin(x), cos(-x) = cos(x), and tan(-x) = -tan(x) to rewrite the expression as:

-sec(x)sin(x) - tan(x)

1 + sec(x)

Next, we can multiply both the numerator and denominator by the conjugate of the denominator, 1 - sec(x), to eliminate the square root in the denominator. This gives:

(-sec(x)sin(x) - tan(x))(1 - sec(x))

(1 + sec(x))(1 - sec(x))

Simplifying the numerator by distributing and combining like terms, we get:

-sec(x)sin(x) + sec(x)tan(x) + tan(x) - sec(x)tan(x)

1 - sec^2(x)

Simplifying further by canceling out the sec(x)tan(x) terms in the numerator, we get:

-tan(x)

1 - sec^2(x)

Finally, we can use the identity 1 - sec^2(x) = sin^2(x) to rewrite the denominator and simplify further:

-tan(x)

sin^2(x)

Therefore, the simplified expression is -tan(x)/sin^2(x).
