Factoring is an important process that helps us understand more about our equations. Through factoring, we rewrite our polynomials in a simpler form, and when we apply the principles of factoring to equations, we yield a lot of useful information. There are a lot of different factoring techniques.

Answer:

The selling price  = $36

Step-by-step explanation:

So

Percent Markup on Cost  (M) = 200% of 12

                                                = 200/100 × 12

                                                = 2 × 12

                                                = $24

Thus the selling price  =  Cost (C) + Markup (M)

                                      = $12 + $24

                                      = $36

Therefore, we conclude that:

The selling price  = $36

Step-by-step explanation:

It is cheaper for a customer to purchase the first plan if they make more than 300 minutes of long-distance calls. The answer is (C) 300.

Let's denote the number of minutes of long-distance calls as x. Then, the total cost of the second plan would be:

Cost of Plan 2 = $10 + $0.05x

The total cost of the first plan is always $25, regardless of the number of minutes of long-distance calls.

So we need to find the value of x at which the cost of Plan 2 exceeds the cost of Plan 1, i.e. when:

$10 + $0.05x = $25

Subtracting $10 from both sides, we get:

$0.05x = $15

Dividing both sides by $0.05, we get:

x = 300

So for values of x greater than 300, the cost of Plan 2 will exceed the cost of Plan 1.

Step-by-step explanation:

The Lounge suite price in total is, $2648.

Given that, $2,000 lounge suite was sold under a hire contract. A deposit of $200 was made. The balance and interest were then paid off in equal monthly instalment of $68 over three years.

Under a rent purchase agreement, a purchaser pays an initial deposit and takes the item away. The purchaser  makes regular repayments (instalments). The instalments embrace each repayment of the debt and also the interest being charged by the seller. At the top of the amount of the agreement, the purchaser owns the item.

As mentioned, the lounge suite was purchased by paying $200 deposit and also the rest quantity through instalments i.e $68 over three years.

The total price of the lounge suite are going to be,

total price = deposit amount + instalments

               = $200 +  $68 over 3years

               = $200 + $68 (3* 12)            ( since, annually has twelve months)

                =$200 + $68(36)

                =$200 + $2448

                =$2648

Therefore the overall price of the lounge suite is, $2648.

[tex] \sf \large \: - 31[/tex]

Step-by-step explanation:

3²−5(2³)

=9−5(2³)

=9−(5)(8)

=9−40

=−31

First, we observe that

[tex]4x-x^2 = x(4-x) = 0 \implies x=0 \text{ or } x = 4[/tex]

and

[tex]4x-x^2 = 4-(x-2)^2 \le 4[/tex]

so that [tex]R[/tex] is in the first quadrant. Any line [tex]y=mx[/tex] that slices this region into two pieces must then have a slope between [tex]m=0[/tex] and [tex]m=4[/tex] (which is the slope of the tangent line to the curve through the origin).

The parabola and line meet at the origin, and again when

[tex]4x - x^2 = mx \\\\ ~~~~ \implies x^2 + (m-4)x = x (x + m - 4) = 0 \\\\ ~~~~\implies x = 4-m[/tex]

with [tex]4x-x^2\ge mx[/tex] for [tex]0\le x\le4-m[/tex].

Now, the total area of [tex]R[/tex] is

[tex]\displaystyle \int_0^4 (4x-x^2) \, dx = \left(2x^2 - \frac{x^3}3\right)\bigg|_0^4 = \frac{32}3[/tex]

so that half the area is 16/3.

The area of the left piece (containing the origin) is

[tex]\displaystyle \int_0^{4-m} ((4x-x^2) - mx) \, dx = \left(\frac{4-m}2 x^2- \frac{x^3}3\right)\bigg|_0^{4-m} = \frac{(4-m)^3}6[/tex]

Solve for [tex]m[/tex].

[tex]\dfrac{(4-m)^3}6 = \dfrac{16}3[/tex]

[tex](4-m)^3 = 32[/tex]

[tex]4 - m = \sqrt[3]{32} = 2\sqrt[3]{4}[/tex]

[tex]\boxed{m = 4 - 2\sqrt[3]{4} \approx 0.825}[/tex]

The expression which could not be used to calculate the total cost of book purchased by 27 students will be 7(20)+7(7) and 7(30)-7(7)  which is option (a) and (b) .

We have given the cost of the book $7 .

Total cost = Cost per book × Total number of students

                 = 7 × 27

                 =  189

(a) 7(20)+7(7) = 140 - 49

                     = 91

On simplifying the expression , we get 91 which is not equal to the total cost 189 . Hence , this expression does not represent the total cost.

(b) 7(30)-7(7) = 210 - 29

                     = 181

On simplifying the expression , we get 181 which is not equal to the total cost 189 . Hence , this expression does not represent the total cost.

(c) 7(30)-7(3) = 210 -21

                     = 189

On simplifying the expression , we get 189 which is equal to the total cost 189 . Hence , this expression represent the total cost.

Answer:

the action of deposing someone, especially a monarch.

Step-by-step explanation:

Answer:

no because the absolute value of -7 is 7 which is greater than the absolute value of 6 which is 6.

First, [tex]f(x)[/tex] is continuous on its domain, so

[tex]\displaystyle \lim_{x\to\alpha^+} f(g(x)) = f\left(\lim_{x\to\alpha^+} g(x)\right) \\\\ ~~~~~~~~~~~~~~~~~~ = \sin\left(\frac\pi6 \lim_{x\to\alpha^+} \frac{\ln\left(\sqrt x - \sqrt\alpha\right)}{\ln\left(e^{\sqrt x} - e^{\sqrt\alpha}\right)}\right)[/tex]

As [tex]x\to\alpha^+[/tex], [tex]\sqrt x-\sqrt\alpha\to0[/tex] and [tex]e^{\sqrt x}-e^{\sqrt\alpha}\to0[/tex], so overall we have an indeterminate form ∞/∞. Apply l'Hôpital's rule and simplify.

[tex]\displaystyle \lim_{x\to\alpha^+} f(g(x)) = \sin\left(\frac\pi6 \lim_{x\to\alpha^+} \frac{\frac1{2\sqrt x\left(\sqrt x - \sqrt\alpha\right)}}{\frac{e^{\sqrt x}}{2\sqrt x\left(e^{\sqrt x} - e^{\sqrt\alpha}\right)}}\right) \\\\ ~~~~~~~~~~~~~~~~~~ = \sin\left(-\frac\pi6 \lim_{x\to\alpha^+} \frac{e^{-(\sqrt x-\sqrt\alpha)} - 1}{\sqrt x - \sqrt\alpha}\right)[/tex]

Substitute [tex]y=\sqrt x-\sqrt\alpha[/tex], so that [tex]x\to\alpha^+\implies y\to0^+[/tex].

[tex]\displaystyle \lim_{x\to\alpha^+} f(g(x)) = \sin\left(-\frac\pi6 \lim_{y\to0^+} \frac{e^{-y} - 1}y\right)[/tex]

The remaining limit is the right-derivative of [tex]e^{-y}[/tex] at [tex]y=0[/tex], so

[tex]\displaystyle \lim_{x\to\alpha^+} f(g(x)) = \sin\left(-\frac\pi6\frac{de^{-y}}{dy}\bigg|_{y\to0^+}\right) \\\\ ~~~~~~~~~~~~~~~~~~ = \sin\left(\frac\pi6\right) = \boxed{\frac12}[/tex]

Answer:

a. [tex]y = -(x+1)^2+4[/tex]

b. [tex]y = \frac{1}{2} (x-2)^2-3[/tex]

Step-by-step explanation:

a. Vertex is (-1, 4)

so you get

[tex]y = a(x+1)^2+4[/tex]

plug in (1, 0) and get the a value

[tex]0 = a(1+1)^2+4\\0 = a*2^2 + 4\\0 = 4a + 4\\-4 = 4a\\a = -1[/tex]

final eq:

[tex]y = -(x+1)^2+4[/tex]

b. Vertex is (2, -3)

so you get

[tex]y = a(x-2)^2-3[/tex]

plug in (0, -1) and get the a value

[tex]-1 = a(0-2)^2-3\\-1 = a*(-2)^2 -3\\-1 = 4a -3\\2 = 4a\\a = \frac{1}{2}[/tex]

final eq:

[tex]y = \frac{1}{2} (x-2)^2-3[/tex]

Answer:

A. (X =4) is the event that the student has four cousins: P(X-4) is the probability of the event that the student has four cousins.

Step-by-step explanation:

An event is an individual outcome or any number of outcomes of a random experiment or trial. An even that contains only one sample point is called a simple event. A compound event contains more than 1 sample point and is formed by the union of simple points.

An event A is said to occur only and if only the outcome of the experiment corresponds to some element of A.

In the given question the first symbolic representation gives an event and the second symbolic representation gives the probability.

The probability of X = 2 or 4 is given by P (X=2) or  P (X=4) symbollically.

So A is the best choice.

The relative frequency gives the probability  so choice B,C and D are wrong.

Answer is correct.

Using addition of polynomials, it is found that:

a) The total amount is: T(t) = -0.028t³ - 0.32t² + 1.6t + 59.

b) $55.5 million was spent on buying new and used vehicles in the fifth year.

To add polynomials, we have to combine the like terms, that is, the terms that have t elevated to the same power.

For this problem, the functions are given as follows:

Hence the total amount is:

T(t) = N(t) + U(t)

T(t) = -0.028t³ + 0.06t² + 0.1t + 17 - 0.38t² + 1.5t + 42.

T(t) = -0.028t³ + (0.06 - 0.38)t² + (0.1 + 1.5)t + 17 + 42.

T(t) = -0.028t³ - 0.32t² + 1.6t + 59.

For the 5th year, the amount is given by:

T(5) = -0.028(5)³ - 0.32(5)² + 1.6(5) + 59 = 55.5.

$55.5 million was spent on buying new and used vehicles in the fifth year.
