8 0

Step-by-step explanation:

step 1. there are 3 right triangles!

step 2. 8/6 = 6/x (definition of right triangle with an altitude)

step 3. 8x = 36 (cross multitude)

step 4. x = 9/2 (divide both sides by 8)

step 5. 6^2 + x^2 = y^2 (pythagorean theorem)

step 6. 6^2 + (9/2)^2 = y^2

step 7. 144/4 + 81/4 = y^2

step 8. 225/4 =y^2

step 9. y = 15/2 = 7.5.

If h (x) = {(-2,3), (0,4), (1,6), (2, 9)}<br><br> then what set of values represent h-1 (x) ?

vfiekz [6]

Answer:

$h^{-1}(x)=\{(3,-2),(4,0),(6,1),(9,2)\}$

Step-by-step explanation:

Given: $h(x)=\{(-2,3),(0,4),(1,6),(2,9)\}$

To find: $h^{-1}(x)$

Solution:

A relation is said to be a function if each and every element of the domain has a unique image in the co-domain.

Inverse of a function exist if it is both one to one and onto.

$h(x)=\{(-2,3),(0,4),(1,6),(2,9)\}$

$h^{-1}(x)=\{(3,-2),(4,0),(6,1),(9,2)\}$

Alan has read 80 percent of a book . He has 16 more pages to finish. How many pages are in the book

Jet001 [13]

Answer:

Step-by-step explanation:

To have 16 more pages means he has 20% more of the book to cover if he has already covered 80%

Let the number of pages in the book be X

20% of X = 16

20/ 100. * X = 16

1/ 5 * X = 16 >>> X = 16 * 5 = 80 pages.

A regular octagon with sides of length 7 and an apothem of length 10.49 has an area of how many square units

Ray Of Light [21]

Answer:

The area of the regular octagon is $293.72\ units^{2}$

Step-by-step explanation:

we know that

The area of the regular polygon is equal to

$A=\frac{1}{2}Pa$

where

P is the perimeter of the regular polygon

a is the apothem

<em>Find the perimeter P</em>

$P=8(7)=56\ units$

Find the area

$A=\frac{1}{2}(56)(10.49)=293.72\ units^{2}$
