The intersection of two planes can be a line true or false

1 answer:

True.

Let's say that you have two pieces of paper that both represent planes. If you cross them, you'll be able to see that the intersection of these two pieces of paper is a line.

Use the remainder theorem to divide 5x^2+9x-2 by x+3. what is the remainder?

Anna [14]

Answer:

A)16

Step-by-step explanation:

Given

f(x)=5x^2+9x-2

Remainder theorem states that when f(x) is divided by x-a then the remainder can be calculated by calculating f(a).

Now Using the remainder theorem to divide 5x^2+9x-2 by x+3 to find the remainder:

f(x)=5x^2+9x-2

f(-3) = 5(-3)^2 +9(-3) -2

=5(9) - 27 -2

= 45-29

= 16 !

Angle. How many sides does the polygon have?

tia_tia [17]

The measures of the four angles of quadrilateral ABCD are 36°, 72°, 108° and 144°

<u>Explanation:</u>

A polygon has three or more sides.

Example:

Triangle has 3 sides

Square has 4 sides

Pentagon has 5 sides and so on.

27)

In a quadrilateral ABCD, the measure of ZA, ZB, ZC and ZD are the ratio 1 : 2 : 3 : 4

We know,

sum of all the interior angles of a quadrilateral is 360°

So,

x + 2x + 3x + 4x = 360°

10x = 360°

x = 36°

Thus, the measure of four angles would be:

x = 36°

2x = 2 X 36° = 72°

3x = 3 X 36° = 108°

4x = 4 X 36° = 144°

Therefore, the measures of the four angles of quadrilateral ABCD are 36°, 72°, 108° and 144°

The bus travels 3 hours going 35 miles per hour. How far does the bus travel in that amount of time? *

3241004551 [841]

The answer is: " 105 mi. " .
____________________________________________

Explanation:
____________________________________________
Note that: "that amount of time" is "3 hours".

→ $\frac{35 mi}{h} * \frac{3h}{1}$ = ? ;

→ The units of "h" (for "hour/s") cancel out to "1" ; since ("h/h = 1") ;

→ and we are left with (35 * 3) mi. = 105 mi.
____________________________________________
The answer is: " 105 mi. " .

What will be the coordinates

svlad2 [7]

N=(-1,-4)
hmm, a 270 counterclockwise rotation is the same as a 90 degree clockwise

so that would become (-4,1)
N'=(-4,1)

How will you know if two variables are proportional on a graph?

MArishka [77]

Answer:

Compare the constants of the two variables.

Changed at the same rate, or by the same factor, then they are directly proportional. For example, since the x-coordinates changed by a factor of 2 while the y-coordinates also changed by a factor of 2, the two variables are directly proportional.
