Is x – 3 a factor of 5x5 – 3x4 + 2x2 – 9x + 12 ?

Answers

Answer 1

Answer:

No

Step-by-step explanation:

Answer 2

Answer:

see explanation

Step-by-step explanation:

If (x - 3) is a factor of the polynomial then f(3) = 0

Given

f(x) = 5[tex]x^{5}[/tex] - 3[tex]x^{4}[/tex] + 2x² - 9x + 12 , then

f(3) = 5[tex](3)^{5}[/tex] - 3[tex](3)^{4}[/tex] + 2(3)² - 9(3) + 12

      = 5(243) - 3(81) + 2(9) - 27 + 12

      = 1215 - 243 + 18 - 27 + 12 = 975

Since f(3) ≠ 0 then (x - 3) is not a factor of the polynomial

Answer:

Yoy answer is x=10

Step-by-step explanation:

We already know what ∠GEF is 23°

so you would have to create an equation like this [tex]23+(5x+1)=7x+4[/tex]

you add 23+1=24 and get [tex]5x+24=7x+4[/tex] subtract 5x on both sides

[tex]24=2x+4[/tex] subtract 4 on both sides

Find the distance between the points (0,2)and (-5,-9)The answer must be a whole number or a fully simplified radical expression do not round up

Answers

Answer:

The answer is

[tex]\sqrt{146} \: \: \: units[/tex]

Step-by-step explanation:

The distance between two points can be found by using the formula

[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(0,2)and (-5,-9)

The distance is

[tex]d = \sqrt{( {0 + 5})^{2} + ({2 + 9})^{2} } \\ = \sqrt{ {5}^{2} + {11}^{2} } \\ = \sqrt{25 + 121} \\ = \sqrt{146} [/tex]

We have the final answer as

[tex] \sqrt{146} \: \: \: units[/tex]

An investor purchased a house 8 years ago for ​$48,000 This year it was appraised at ​$73,500 Complete parts​ (a) through​ (d) below. ​(a) A linear equation V=mt+b,0

Answers

Answer:

b = $48000, m = $3187.5 / year

Step-by-step explanation:

The equation of a linear function is given as y = mx + b, where m is the rate of change, b is the value of y when x = 0, y = dependent variable and x = dependent variable.

Given that V = mt + b:

b = initial price of the house at 0 years = $48000

V = mt + 48000, At 8 years the house is appraised at ​$73,500

73500 = 8m + 48000

8m = 73500 - 48000

8m = 25500

m = 3187.5

Jackson was selling cups of lemonade. On Saturday, he sold a total of 14 cups. On Sunday he sold cups at a steady rate of 3 cups per hour. Set up and solve an equation to find how many hours, h, it took Jackson to sell 47 cups (including those from Saturday).

Answers

Answer:

(47-14) h ÷ 3 =11

Step-by-step explanation:

47-14=33

33 divided by 3 is 11

Jackson takes 11 hours to sell 47 cups.

How to form an equation?

Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.

In other words, an equation is a set of variables that are constrained through a situation or case.

Let's say the number of hours that Jackson sold his cups on Sunday.

Now,

Saturday cups + Sunday cups = Total cups.

14 + 3x = 47

3x = 33

x = 11

Hence "Jackson takes 11 hours to sell 47 cups".

Perpendicular

Step-by-step explanation:

For this problem, it is important to note two things.  One line is completely vertical, and the other line is completely horizontal.

The line y=9 is completely horizontal at the y-value at 9.  The line x = 2 is completely vertical at the x-value at 2.

Hence, these two lines would be perpendicular.

Cheers.

Answer:

Perpendicular.

Since it makes a huge cross +, which we want it to be, we need the lines to intercept and it makes a right angle. That means it is perpendicular.

A truck can be rented from company A for $130 a day plus $0.20 per mile. Company B charges $50 a day plus $0.60 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for company A and company B

Answers

Answer:

200 miles

Step-by-step explanation:

Company A

Daily charge = $130Per mile = $0.20x miles per day = 130 + 0.2x

Company B

Daily charge = $50Per mile = $0.60x miles per day = 50 + 0.6x

Assume x miles that makes same amount for both options, then:

130 + 0.2x = 50 + 0.6x0.6x - 0.2x = 130 - 500.4x = 80x = 80/0.4x = 200 miles
