Answer 1
Answer:

Answer: (x - 2)(x + 2)(2x + 1)

Step-by-step explanation:

        q                     p

f(x) = 2x³ + x² - 8x - 4

rational root theorem: (p)/(q) = +/- (1, 2, 4)/(1, 2) so the possible roots are: +/- 1, 2, 4, (1)/(2)

Let's try x = 2

2  |   2     1     -8     -4

   |   ↓     4     10     4

       2     5     2      0   remainder is 0 so (x - 2) is a factor

0 = (x - 2)  (2x² + 5x + 2)

0 = (x - 2)  (x + 2)(2x + 1)
Answer 2
Answer: Answer: X - 2 ( X + 2) (2 x + 1)

A line is drawn through (–4, 3) and (4, 3). Which describes whether or not the line represents a direct variation?The line represents a direct variation because = .
The line represents a direct variation because it is horizontal.
The line does not represent a direct variation because it does not go through the origin.
The line does not represent a direct variation because –4(3) ≠ 4(3).

Answers

The line does not represent direct variation because it does not go through the origin. In fact, it happens to be a horizontal line whose equation is : y = 3.

A line y= k x, represents a direct variation if , k=(y)/(x)

As,line passes through (-4,3) and (4,3).

Equation of line passing through two points is,  

(y-3)/(x+4)=(3-3)/(4+4)\n\n y-3=0

Given by the formula: (y-y_(1))/(x-x_(1))=(y_(2)-y_(1))/(x_(2)-x_(1))

As, the line does not pass through origin , so the line passing through (-4,3) and (4,3) does not represent direct variation.

Option (C)=The line does not represent a direct variation because it does not go through the origin.

a marching band requires a tuba player to begin at the 50 yard line of a football field perpendicular to the 40 yard line. He then makes a 30 degree turn and marches at a diagonal back to the 50 yard line.Once he reaches the 50 yard line he must march forward until; he reaches his original starting position.If the tuba player travels 18 invhes with each marching pace how many paces must he take to complete the routine?

Answers

20/3 paces must he take to complete the routine.

How to find the steps he must take to complete the routine?

The marching band begins at the 50-yard line of a football field and marches perpendicular to the 40-yard line.

Hence,

So when the tuba players travel 18 inches with each marching pace, the paces are:

50+30+40 / 18 = 20 / 3

So, the answer is 20 / 3  paces.

Here, Distance divided by speed equals steps.

well yes, i took 50, 40, 18 and added two 50. I then got 238 as the answer but honestly math is like my worse subject. I tried looking like examples on how to do it and in one of my math books but this what i got. I really hope i helped tho :)

Does a triangle with side lengths 5, 5 and 5root2 form a right triangle?

Answers

If it is a right triangle, then 5^2+5^2 = (5*sqrt(2))^2
25 + 25 = (5*1.414...)^2 =
50 =(7.0710678119) ^2
and  7.0710678119^2 = 50 so it is a right triangle.
To be specific, it is an isosceles right triangle.

200 books ; 75% decrease

Answers

the answer is 150 because you figure that 75 is 3/4 of 100. and 1/4 of 200 is 50. or you can do

the ratio of apples to oranges on the fruit stand was 31:11 if there were 2,940 apples and oranges altogether, how many apples are there

Answers

First you add 31 and 11 and you get 42, then you do 2,940 divided by 42 which is 70. Then you multiply 70 by 31, and you get 2, 170, 
and there are 2,170 apples which is the answer

What type of line would you mark the center of a two-way road

Answers

There are 2 types of line that you can mark the center of a two-way road.

1) passing permitted - it is a broken line marking found in the center of the two-way road. It means that passing other cars is permitted.

2) no passing zones and edge line - it is composed of a combination of solid yellow line, single broken-yellow line, double solid yellow line. It means overtaking or passing is never permitted.
