Answer:

It'll have an open circle on both 7 and 21, with a line connecting.

Which is none of the options, unless one isn't shown?

Step-by-step explanation:

-23 > -4x + 5 > -79

So:

-23 > -4x + 5

-23 - 5 > -4x

-4x < -28

x > -28 / -4

x > 7

-4x + 5 > -79

-4x > - 79 - 5

-4x > -84

x < -84 / -4

x < 21

saveliy_v [14]

Answer:

$C(3)=17.69\ ppm$

Step-by-step explanation:

Given:

Given polynomial function is.

$C(h)=-0.09h^{2} +3.5h+8$

Hours $h=3$

We need to find the concentration of the antibiotic after 3 hours.

Solution:

Rewrite the given polynomial function as.

$C(h)=-0.09h^{2} +3.5h+8$

Substitute $h=3$ in given polynomial function.

$C(3)=-0.09(3)^{2} +3.5\times 3+8$

$C(3)=-0.09\times 9+10.5+8$

$C(3)=-0.81+10.5+8$

$C(3)=-0.81+18.5$

$C(3)=17.69\ ppm$

Therefore, the concentration of the antibiotic after 3 hours $C(3)=17.69\ ppm$ .
