Answer:

x = 8 \sqrt{3}

y = 60

z = 30

Step-by-step explanation:

To find x, use pythagorean theorem,

{x}^{2}  +  {8}^{2}  =  {16}^{2}

{x}^{2}  + 64 = 256

{x}^{2}  = 192

x=13.9 or 8 times sqr root 3( see later)

To find y, use cosine ratio.

\cos(y)  =  \frac{8}{16}

\cos(y)  =  \frac{1}{2}

y = 60

To find z, use triangle interior theorem

90 + 60 + z= 180

150 + z = 180

z = 30

Since this a 30-60-90 triangle, side x could be also written as

8 \sqrt{3}

What equals -36 when added but equals 160 when multiplied.
Irina18 [472]
X + y = -36

x * y = 160

x = -36 - y

(-36-y) * y = 160

-36y - y^2 = 160

y^2 + 36y + 160 = 0

y = -5.19  and x = -30.8

or

y = -30.8 and x = -5.19

You can write them in this form too

x+ysqrt(z)

What are the zeros in the function f(x)=(2x+6)(x-4)
Shtirlitz [24]

Hello from MrBillDoesMath!

Answer:

x = -3, 4

Discussion:

The zeroes of f(x) are the x values where

2x + 6 = 0   =>  x = -3

and

x - 4 = 0   => x = 4

Thank you,

MrB

A cashier can ring up 12 items per minute. How long will it take the cashier to ring up 72 items? ​
Talja [164]

Answer:

So it will take 6 minutes to ring up 72 items.

Step-by-step explanation:

Well this seems pretty simple just have to reads the question and know what to find.

So what we know :

A cashier can ring up 12 items per minute

So :

1 minute = 12 Minutes

And we have to find :

How long for 72 items

So since we know he can do 12 in a minute and it is asking how many minutes it will take for 72 we can divide.

So :

72 / 12

=

6

So it will take 6 minutes to ring up 72 items.

I hope this helps!

If you have any questions or concerns feel free to message me or comment. :)
