patriot [66]

Answer:

Slope =-1/4

Step-by-step explanation:

y=mx+n

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

A(-1,19).... x1 =-1, y1=19

B(11,16)..... x2=11, y2=16

Slope=(16-19)/(11-(-1))=(-3)/(11+1)=-3/12=-1/4

The right triangle above has height h centimeters and hypotenuse t centimeters. What is the area, in square centimeters, of the

White raven [17]

Answer:

$A = \frac{h\sqrt{t^{2} - h^{2}}}{2}$

Step-by-step explanation:

Right triangle:

height h, width w, hypotenuse h

Area is: $A = \frac{h*w}{2}$

Pytagoras theorem: $h^{2} + w^{2} = t^{2}$

In this question:

To find the area, in terms of h and t, we have to write w as a function of h and t. So

$h^{2} + w^{2} = t^{2}$

$w^{2} = t^{2} - h^{2}$

$w = \sqrt{t^{2} - h^{2}}$

So the area is:

$A = \frac{h*w}{2}$

$A = \frac{h\sqrt{t^{2} - h^{2}}}{2}$

Which two ratios form a proportion A) 1/2 and 2/7 B) 2/1 and 7/14 C) 1/2 and 7/14 D) 2/1 and 14/21

Romashka [77]

1/2 * 2/2 = 2/4 which is not 2/7

2/1 * 7/7 = 14/7 which is not 7/14

1/2 * 7/7 = 7/14 which is 7/14 yes

2/1 * 7/7 = 14/7 which is not 14/21 no
