F(x)=(x−2)^2 -9 Find the solutions

Mathematics
1 answer:
Julli [10]4 years ago
8 0

Answer:

x=1 or x=-5

Step-by-step explanation:

The given function is

f(x) =  {(x - 2)}^{2}  - 9

The solutions are the roots of the function.

This is where the graph of the function touches the x-axis.

We set the equation to zero to get:

{(x - 2)}^{2}  - 9 = 0

{(x - 2)}^{2}  = 9

We take square root to get:

{(x - 2)}  =  \pm \sqrt{9}

x - 2=  \pm 3

x= 2 \pm 3

x= 2  - 3 \: or \: x = 2 + 3

x =  - 1 \: or \: x = 5

The probability is 0.1587.

The z-score associated with this is found using the formula

z = (X-μ)/σ = (100-90)/10 = 10/10 = 1.0

Using a z-table (http://www.z-table.com) we see that the area to the left of, less than, this is 0.8413.  We want the area greater than, so we subtract from 1:
1 - 0.8413 = 0.1587

The booster club recently bought new baseball equipment. They spent $18 per glove and $24 dollars per catching mask and spent a
hammer [34]

Answer:

given below

Step-by-step explanation:

let the number of gloves be y

then number of masks is y + 8

therefore a equation can be formed:

18(y) + 24(y + 8) = $612

18y+24y+192=612

42y=420

y=$10

each glove cost $10

therefore each masks cost $18
