A mapping diagram showing a relation, using arrows, between input and output for the following ordered pairs: (negative 3, negat

ive 9), (2, negative 6), (negative 5, 4), (1, 2), (6, 0). What is the domain of the function shown in the mapping? {x | x = –5, –3, 1, 2, 6} {y | y = –9, –6, 0, 2, 4} {x | x = –9, –6, –5, –3, 0, 1, 2, 4, 6} {y | y = –9, –6, –5, –3, 0, 1, 2, 4, 6}

20. Suppose you need to re-administer this injection at the point when the concentration is less than 0.5%. If the first injecti
IceJOKER [234]
Given that the function

C(h)=\frac{2h^2+5h}{h^3+8}

models the concentration of a medication in the bloodstream (as a percent), hours (h) after its injection into muscle tissue.

The number of hours it will take for the concentration of the injection to be less than 0.5% is given by:

0.5\ \textgreater \ \frac{2h^2+5h}{h^3+8} \\ \\ \Rightarrow0.5(h^3+8)\ \textgreater \ 2h^2+5h \\ \\ \Rightarrow h^3+8\ \textgreater \ 4h^2+10h \\ \\ \Rightarrow h^3-4h^2-10h+8\ \textgreater \ 0 \\ \\ \Rightarrow h\ \textgreater \ 5.54

Given that the first injection was given at 8:00 am, the time the next injection should be given is 2 pm.

If you could explain how I would get this answer also that'd be great
NeX [460]
For now, we can’t get a definite answer. We can model with an equation, but we cannot find the absolute amount Jocelyn will earn, as her hourly rates are both variables. All we must do to create an equation for this is multiply the amount of hours by the rate and add. You could model like this:
25n + 15x = total amount earned

Stuck on these two shapes <br>need help in working out the surface area​
ArbitrLikvidat [17]

Answer:

Part 1) The surface area of the triangular prism is SA=660\ cm^{2}

Part 2) The surface area of the trapezoidal prism is SA=2,864\ cm^{2}

Step-by-step explanation:

Part 1) Find the surface area of the triangular prism

we know that

The surface area is equal to

SA=2B+PL

where

B is the area of the triangular base of the prism

P is the perimeter of the base of the prism

L is the length of the prism

<u>Find the area of the triangular base B</u>

B=\frac{1}{2}(10)(12)=60\ cm^{2}

<u>Find the perimeter of the base P</u>

P=10+13+13=36\ cm

L=15\ cm

substitute the values

SA=2(60)+(36)(15)=660\ cm^{2}

Part 2) Find the surface area of the trapezoidal  prism

we know that

The surface area is equal to

SA=2B+PL

where

B is the area of the trapezoid base of the prism

P is the perimeter of the base of the prism

L is the length of the prism

<u>Find the area of the trapezoid base B</u>

B=\frac{1}{2}(28+15)(8)=172\ cm^{2}

<u>Find the perimeter of the base P</u>

P=15+28+10+10=63\ cm

L=40\ cm

substitute the values

SA=2(172)+(63)(40)=2,864\ cm^{2}
