If you have a plant and it grows 21.3 centimeters in 1 day what would be the x and y

DochEvi [55]

Answer:

Step-by-step explanation:

Here we want to present growth as a function of time; the growth depends upon the number of days that go by. So, growth(y) is the dependent variable and time (in days, x) is the independent variable.

Find the diameter of the base of a right cylinder if the surface area is 128(pi) and the height is 12cm.

Gelneren [198K]

$d=2r\\
A=128 \pi \\
A=2 \pi r^{2} +2 \pi rh \\\\
2 \pi r^{2} +2 \pi rh = 128 \pi \\
2 r^{2} +2rh = 128\\
2 r^{2}+24r-128=0\\
r^{2}+12r-64=0\\
delta=400\\
r_{1/2} = -16/4 \\
r=4cm\\
d=8cm\\
$

Radius / diameter as a length cannot be negative, that's why '-16' is wrong.
