If the height of the base is 15 and the width of the base is 8 what is the length of the hypotenuse

tino4ka555 [31]

Answer:

The length of the hypotenuse is 17.

Step-by-step explanation:

$15^2 + 8^2 = 17^2.$

I found this out by doing:

15 x 15 = 225

8 x 8 = 64

225 + 64 = 289

$\sqrt{289} = 17$

Hope this helps you! :)

Use the domain and range of each of the following relations to determine which is a function.

Sergeeva-Olga [200]

Answer:

a) Function

b) Not a function

c) Function

d) Not a function

Step-by-step explanation:

a) Domain = { 7,-6,2}

Range = {5,0,3}

It is a function as every value in domain has some and unique value mapped to it in Range

Domain = { 7,-6,2}

Range = {5,0,-2,3}

It is not a function as -6 value in domain has two values mapped to it in Range

Domain = { 7,2}

Range = {-6,-7}

It is a function as every value in domain has some and unique value mapped to it in Range

Domain = { 7,-6}

Range = {5,0,3}

It is not a function as 7 value in domain has two values 3 and 5 mapped to it in Range

Can someone answer this soon?!?

Sever21 [200]

First get all the terms on the same side:

$x^2 + 7x - 4 = 0$

Now solve using the quadratic formula which is:

$\frac{-b±\sqrt{b^2 - 4ac} }{2a}$

Plug in the values:

$\frac{-7± \sqrt{49-4(1)(-4)} }{2}$

So the answer is:

$\frac{-7 ± \sqrt{65} }{2}$
