Plant cells tend to be round and animal cells tend to be circular. True or False

True

Explanation:

Plant cells come in all shapes and sizes. Some are round, some are brick shaped, others look like shoe strings. The one thing they have in common is a rigid cell wall. This means that they cannot change shape very easily. If it's false, let me know it is false and i can change my answer for you

True

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.

its first and third is your answer i did the qustion the fourth isnt right
