The construct a line through P that is  perpendicular to the line.

Step-by-step explanation:

Given that,

Construct a line through P that is  perpendicular to the line.

We need to construct a perpendicular line P

Using given data

We draw an arc across the line on each side of the point P.

Now, from each arc on the line, draw another arc on the opposite side of the line from the point P.

The  point P to the point where the arcs intersect Q.

Hence, The construct a line through P that is  perpendicular to the line.

Answer:

We have to represent 1/4 in the number line .

So simply will first write it in Fraction form that is

So we have to represent it on number line .

1/4 we have to mark on the right side of number line because it is a positive number having no negative number . That is why we will mark it on the right side of the number line .

As we know the denominator is 4 so between every number we will keep four points distance.

After the zero the first point is number 1 and number 2 and number 3 and so on ...

The four points will consider number 1 , 2 , 3 , 4 and so on ...number after four points I have written 1 because there is the denominator 4 so we should keep 4 points distance in each number .

So , The number 1 we will mark and write the denominator 4

Answer:

1) 350

2) 195.83

Step-by-step explanation:

Tuition fee = $12, 000 per year.

30% of it's being paid off by the scholarship, so she'll have to pay:

[tex] = 12000 - ( \frac{30}{100} \times 12000) [/tex]

[tex] = 12000 - 3600[/tex]

[tex] = 8400[/tex]

She'll have to pay $ 8400 by herself, her savings.

If she's saving $ 8400 for two years, she's actually saving $ 8400 for 24 months!

for one month, it'll be

= 8400/ 24

= $ 350 per month

one year fee = $ 10, 700

uncle pays half of it, I.e., 10700/ 2

= $ 5, 350

he gets a grant for $ 3,000

so, the part of the fee he ain't paying

= 5,350 + 3000

= $ 8,350

So, he'll have to save:

= 10,700 - 8,350

= $ 2,350

that is per year,

for per month = 2350/ 12

= $ 195.83

[The question's not wholly right! Since, (a+b) has a and b in it, it already is in terms of a and b. Here, we'll be representing (a+b) in terms of ab]

Answer:

[tex]\mathsf{\sqrt{10ab} }[/tex]

Step-by-step explanation:

We have the rules of indices, one of which is:

[tex]\boxed{\large{\mathfrak{(a+b)^2=a^2+b^2+2ab}}}[/tex]

Indices are the powers, the numbers written as superscript in front of a variable or the numbers that come along with "^". It shows how many times a number is to be multiplied by itself.

In the question, we're provided with one equation, i. e.,

And, were asked to find out the value of (a+b) in terms of ab.

The above rule has variables that fit in the question efficiently!

So, instead of solving for (a+b), we'll be solving for (a+b)²,  then go for (a + b):

=> (a + b)² = (a² + b²) + 2ab

from eqn. (¡):

=> (a + b)² = 8ab + 2ab

=> (a + b)² = 10ab

taking under root on both the sides:

=> (a + b) = [tex]\mathsf{\sqrt{10ab} }[/tex]

That's the answer,  [tex]\mathsf{\sqrt{10ab} }[/tex]!

Answer:

'its a remix and im comin wih dat bow bow bow'

Step-by-step explanation:

Answer: y = 2x + 1

Step-by-step explanation:  

Rewrite the equation in standard form:

x+2y=5

2y = -x + 5

y = -(1/2)x + (5/2)

A line perpendicular to this would have a slope that is the negative inverse of the reference line slope, -(1/2), here.  The new slope would be 2.  The y-intercept, (5/2), will change, so we'll just use b for the new y-intercept, and calculate it later:

y = 2x +b

We know that point (3,7) lies on the new line (it is a solution to the equation), so we can use this point to find the new y-intercept, b.

7 = 2*3 + b

b = 1

The perpendicular line is y = 2x + 1, and goes through point (3,7)

Answer:

$9200

Step-by-step explanation:

Since he works 40 hours a week and would make $23 for every hour with option A, we just multiply 40 by 23

40 x 23 = 920

This means 10% of the sales will need to equal to 920

Let x = sales

We multiply x by 0.1 to get 920

0.1x = 920

Divide both sides by 0.1

0.1x/0.1 = 920/0.1

x = 9200

[tex]y=-0.3(x-2)^2+2[/tex]

Step-by-step explanation:

We know that the parabola faces downard, and hence must have a negative first term, so that eliminates the first and third options.

The vertex of the parabola has an x-value of 2, so it must be of the form [tex]a(x-3)^2+c[/tex].

Combining these, we have that the answer is [tex]\boxed{y=-0.3(x-2)^2+2}[/tex]

Answer:

x= 104

Step-by-step explanation:

Angle in a triangle is 180

35+41+x=180

76+x=180

x=180-76

x=104

Answer:

x = 128 degrees

Step-by-step explanation:

So we know that a triangle's interior angles should add up to 180 degrees.

We also know that when a triangle has that little square in a corner, that corner is equal to 90 degrees.

With these clues, we can figure out that the last interior angle is equal to:

180 - (38+90) = 52, however this isn't the answer we are looking for.

We also know that a straight line is 180 degrees. Therefore, to find the exterior angle we just subtract the interior angle from 180 degrees:

180 - 52 = 128

x = 128

6x² - 20x + 6

Step-by-step explanation:

[tex]\begin{aligned}\tt\left(x-3\right)\left(6x-2\right)&=\tt 6x^2-2x-18x+6\\&=\tt 6x^2 -20x+6\end{aligned}[/tex]

Answer:

6x^2 - 20x + 6

Step-by-step explanation:

(x - 3) (6x - 2)

6x^2 - 18x - 2x + 6

6x^2 - 20x + 6

The value to be added to both sides of the equation to make the left side a perfect square trinomial is; -36.

To make the equation x2 – 12x = 1 look similar to the completing the square kind of expression where the left hand side of the equation becomes a perfect square, we must do the following;

In this scenario, the term (x² - 12x) can be rewritten as; (x - 6)² - 36.

This so because the expansion of (x - 6)² becomes;

Therefore, there's a need to subtract 36 from both sides of the equation so that the equation x2 – 12x = 1 is retained.

Therefore, the value to be added to both sides of the equation to make the left side a perfect square trinomial is; -36.
