An EpiPen Jr., used to treat anaphalactic allergic reactions, contains 0.15 mg of epinephrine. The concentration of epinephrine in each syringe is 0.50 mg/mL. What is the volume, in milliliters (mL), of solution in each syringe?

where is the following

explanation:

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
