Answer:

-15x^5 + 26x^4 - 12x^3 + 35x^2 - 33x - 3

Step-by-step explanation:

(5x^3 - 2x^2 + 3x - 8) + (-3x^2 + 4x + 1)

do foil but with extra terms

-15x^5 + 20x^4 + 5x^3

+6x^4 - 8x^3 - 2x^2

-9x^3 + 12x^2 + 3x

+ 24x^2 - 32x - 8

combine like terms

(-15x^5 + 26x^4 - 12x^3 + 34x^2 - 29x - 8) - (4x - x^2 + 5) or -4x + x^2 - 5

-15x^5 + 26x^4 - 12x^3 + 35x^2 - 33x - 3

Using translation concepts, it is found that the function that would meet Daniel's needs is:

g(x) = -cf(x) - b, c > 1, b > 0

A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction in it's definition.

In this problem, the parent function is f(x).

The total cost of the two shirt Maggie will pay after including the sales tax is $18.105.

The cost price per unit is the amount of money required to buy one unit of a brand or goods.

To find the cost price per unit, divide the total amount of cost of the goods to the total number of goods.

The cost of one shirt bought by the Maggie is $8. 50 each. Thus, the cost of the 2 shirts is,

[tex]C=2\times8.50\\C=17[/tex]

Thus, the total cost of the two shirts is $17.

Now, there is a 6. 5% sales tax on the selling price. Thus, the cost of the 2 shirts after the sales tax is,

[tex]C=17+17\dfrac{6.5}{100}\\C=17+1.105\\C=18.105[/tex]

Hence, the total cost of the two shirt Maggie will pay after including the sales tax is $18.105.

Answer:

y-intercept = (0, 8)

x-intercepts = (4, 0) and (-2, 0)

vertex = (1, 9)

5th point = (2, 8)

Step-by-step explanation:

As the coefficient of x² is negative, the curve will be "n" shaped.

y-intercept

crosses the y-axis when x = 0

substitute x = 0 into the function and solve for y:

[tex]\implies y=-(0)^2+(2 \times 0)+8=8[/tex]

Therefore, y-intercept = (0, 8)

x-intercept

crosses the x-axis when y = 0

set the function to zero and solve for x:

[tex]\implies -x^2+2x+8=0[/tex]

[tex]\implies x^2-2x-8=0[/tex]

[tex]\implies (x-4)(x+2)=0[/tex]

[tex]\implies x=4, x=-2[/tex]

Therefore, x-intercepts = (4, 0) and (-2, 0)

vertex

vertex form:  [tex]y=a(x-h)^2 +k[/tex],  where (h, k) is the vertex

expand vertex equation:  [tex]y=ax^2 -2ahx+ah^2 +k[/tex]

compare coefficients with original function: [tex]y=-x^2+2x+8[/tex]

[tex]\implies a=-1, h=1, k=9[/tex]

So vertex = (1, 9)

5th plot point

You can choose any value of x and input it into the equation for y, but for symmetry, I have chosen to find the other value of x (aside x = 0) when y = 8

[tex]\implies -x^2+2x+8=8[/tex]

[tex]\implies -x^2+2x=0[/tex]

[tex]\implies x^2-2x=0[/tex]

[tex]\implies x(x-2)=0[/tex]

[tex]\implies x=0, x=2[/tex]

Dime is one-tenth of a dollar, while nickle is one-twentieth part of a dollar. Jaime has got 22 dimes and 4 nickle coin in this case.

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

For the given case, since number of dimes is given in terms of number of nickels, so lets assume that:

Since 1 nickle's cost = $0.05,

thus, x nickles' cost = [tex]x \times 0.05[/tex] (in dollars)

And as 1 dime's cost = $0.10,

thus, 14 + x dimes' cost = [tex]0.10 \times (14 + x)[/tex] (in dollars)

Total amount Jamie have = Amount by nickles + Amount by dimes

Total amount Jamie have = [tex]0.10(14+x) + 0.05x[/tex]  (in dollars) = $2.60 (as given in the problem)

Thus, we get:

[tex]0.10 (14+x) + 0.05x = 2.60\\1.4 + 0.10x + 0.05x = 2.60\\\\\text{Subtracting 1.4 from both the sides}\\\\0.15x = 1.2\\\text{Dividing both the sides by 0.15}\\\\\dfrac{0.15x}{0.15} = \dfrac{1.2}{0.15}\\\\x = 8\\[/tex]

Thus, Jamie got  x = 8 nickles.

And number of dimes he got = x + 14 = 8 + 14 = 22

Thus,  Jaime has got 22 dimes and 4 nickle coin in this case.
