Franco was told that he had mycarditis. he went home and researched the disease, and he determined that he had
a a tumor in the muscles of the heart.
b a tumor in the blood vessels.
c inflammation of the muscular wall of the heart.
d inflammation of the blood vessels.

C) inflammation of the muscular wall of the heart.

Explanation:

"Myo-" means "muscle," "card-" pertains to the heart, and finally, "-itis" relates to an infection, which can cause inflammation. If you know all of these things, then you can figure out that Franco has an infection in the muscle of his heart (which also causes inflammation) :)

Cheers!

chemistry sucks a**

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.
