Need understanding this math. each will have vertices a, b and c with a point d lying on the line segment ab. 1. if ac = 15, cb = 20, angle acb = 90◦ and angle adc = 90◦ , what is cd? 2. if ac = 15, cb = 20, ab = 25 and cd = 12, what is ad? what is db?

1. C is the right angle so AB is the hypotenuse and AD is the altitude to the hypotenuse.

The hypotenuse is

The area calculations must match. Let h=CD

12

2. This is the same triangle as above. We seek x=AD and DB=25-x

AD=9 and DB=25-9=16

AD=9, DB=16

idk

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
