Answer 2

Answer:

[tex] f(-8) = -25 [/tex]

Step-by-step explanation:

[tex] f(x) = -x^2 - 3x + 15 [/tex]

[tex] f(-8) = -[(-8)^2] - 3(-8) + 15 [/tex]

[tex] f(-8) = -(64) + 24 + 15 [/tex]

divide the polynomial 3x^4-6x^2-x/x=

Answers

Answer: 3x^3-6x-1

Step-by-step explanation:

Take out an x from everything. Numbers that have powers will just go down a power (ex- 3x^4 would go to 3x^3) and if you have just an x then it turns into one.

The polynomial by the division is equal to [tex]3x^3-6x-1[/tex]

What is a polynomial?

They are mathematical expressions involving variables raised with non negative integers and coefficients(constants who are in multiplication with those variables) and constants with only operations of addition, subtraction, multiplication and non negative exponentiation of variables involved.

We are given the polynomial

[tex]3x^4-6x^2-x/x[/tex]

We need to divide the polynomial by x.

[tex]3x^4-6x^2-x/x[/tex]

Then we need to factor out x

[tex]x(3x^3-6x- 1)/x[/tex]

The answer is [tex]3x^3-6x-1[/tex]

Unit Conversion

We need to recall two basic unit conversions for length:

1 inch = 2.54 cm

1 meter = 100 cm

We are given a length of 13 meters. Converting to centimeters:

13 * 100 = 1300 cm

(B) p(x)=x^2-14x+11

(C) p(x)=x^2+14x+11

(D) p(x)=x^2+3x-154

Answers

Answer:d

Step-by-step explanation:

The required function is [tex]P(x)=x^2+3x+154[/tex]. So, option D is correct.

Important information:

The solutions of [tex]p(x)=0[/tex] are [tex]-14[/tex] and 11.

We need to find the function p(x).

Function:

If [tex]x=c[/tex] is a solution of [tex]p(x)=0[/tex], then [tex](x-c)[/tex] is a factor of p(x).

It means [tex](x+14)[/tex] and [tex](x-11)[/tex] are two factor of p(x).

[tex]P(x)=(x+14)(x-11)[/tex]

[tex]P(x)=x^2-11x+14x+154[/tex]

[tex]P(x)=x^2+3x+154[/tex]

Therefore, the correct option is D.

y = 2x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 2, thus

y = 2x + c ← is the partial equation

To find c substitute (3, - 1) into the partial equation

- 1 = 6 + c ⇒ c = - 1 - 6 = - 7

y = 2x - 7 ← equation of line

Can someone help me with this question it’s 7.55 x 4.5

Answers

Answer:

33.975

Step-by-step explanation:

If you are going to multiply this by hand, make sure that you add a zero to the end of 4.5 so that it is 4.50. Because there are four decimal places, you need to make sure your answer has four decimal places as well. Then add a row of zeroes to the bottom because anything times zero equals zero. Next, add a zero in the hundredths place and multiply 5 from 4.50 to 7.55. Then, do the same with the 4. Add all your numbers together and you should get 33.9750 or 33.975.

Jessica earns 2,000 per month as a saleswomen. In addition to the salary she earns 80 per product that she sells. If her goal is to earn 10,000 per month, how many products does she need to sell

Answers

Answer:

100 products

Step-by-step explanation:

Jessica earns 2,000 per month as a sales woman

In addition to the salary she earns 80 per product that she sells

Her goal is to earn 10,000 per month

Therefore the number of products that will be sold to attain 10,000 can be calculated as follows

= 80×100

= 8,000

= 8,000+2,000= 10,000

Hence she needs to sells 100 products to attain 10,000

The perimeter of a kite is 50 mm. The length of one of its sides is 1 mm more than twice the length of another. Find the length of the LONGEST side of the kite. Only write the value of the longest side.

Answers

Answer:

The length of the longest side is 13mm

Step-by-step explanation:

Represent the two sides with a and b, where a is the longest

[tex]Perimeter = 50[/tex]

[tex]a=b + 1[/tex]

Required

Determine the length of the longest side

Perimeter of a kite is calculated as thus:

[tex]Perimeter = 2(a + b)[/tex]

Make b the subject in [tex]a=b + 1[/tex]

[tex]b = a -1[/tex]

Substitute a - 1 for b and 50 for Perimeter in [tex]Perimeter = 2(a + b)[/tex]

[tex]50 = 2(a + a - 1)[/tex]

Divide through by 2

[tex]25 = a + a - 1[/tex]

[tex]25 = 2a- 1[/tex]

Add 1 to both sides

[tex]25 + 1 = 2a - 1 +1[/tex]

[tex]25 + 1 = 2a[/tex]

[tex]26 = 2a[/tex]

Solve for a

[tex]a = 26/2[/tex]

[tex]a = 13[/tex]

Hence, the length of the longest side is 13mm
