The abscissa of the ordered pair, that is the x-coordinate, is equal to 1 and the ordinate, the y-coordinate, is equal to -1. In the cartesian plane, this point lies in the fourth (IV) quadrant. The standard position of the angle is that which has one of its side is in the x-axis.

Solve for the hypotenuse of the right triangle formed.
           h = sqrt((-1)² + (1)²) = √2
Below items show the calculation for each of the trigonometric functions.

 sin θ = opposite/hypotenuse = y/h = (-1)/(√2) = -√2/2
 cos  θ = adjacent/hypotenuse = x/h = (1)/√2 = √2/2
tan θ = opposite/adjacent = y/x = -1/1 = -1

If f(x)=3/x+2-_/x-3

To find f(19),we would insert (19) as x into the equation:

f(19)=3/(19)+2-_/19-3
=3/21-_/16
=1/7-4
=-27/7

Hope it helps!

If the teacher has 30 students and 10% left,how much students does she have now
garri49 [273]

Answer:

She has 27 students now.

Step-by-step explanation:

Given :

The teacher has 30 students

10% students left.

To find : how much students does she have now?

Solution :

Since we are given that teacher has 30 students .

And 10% of students left

⇒ 10% of 30


⇒\frac{10}{100} *30


⇒\frac{300}{100}


⇒3


Thus, 3 students left .

She had 30 students . three students left.

So, now she have 30 - 3 = 27 students .

Hence she has 27 students now.

What the answer please!!!!!
Mariana [72]

Answer:

Step-by-step explanation:

To find y=mx+b we need to identify two points. I picked (20,45) and (50,65)

From these two points we can find the slope, m.

m=(y2-y1)/(x2-x1)

m=(65-45)/(50-20)

m=20/30=2/3 so now our line is

y=2x/3+b, we can solve for b using either point, I’ll use (20,45)

45=2(20)/3+b

45=40/3+b

b=45-40/3

b=(135-40)/3

b=95/3 so the line is

y=(2x+95)/3
