That is not true. To find the midpoint of a line, you must add the values of x’s together and divide by 2 and then add the values of y together and divide by 2. The formula is (x1+x2/2 , y1+y2/2)
Answer: Hello there!
A model to see the growth of a certain population is the exponential model.
If the initial population is P, then the model can be written as
Where t is the time, and r is growth rate.
and f(0) = P
Then we want to know the time needed for the initial population to be doubled, this is f(x) = 2P, where x is the time that we want to find.
then
then x= ln(2)/r
Y = mx + c , it’s the equation of a straight line and for each picture they got the same value of m which means every set has same gradient.
Answer:
a) 16 in³
Step-by-step explanation:
Vol (cyl) = πr²h = 54
Vol (cone) = πr²h/3
54/3 = 16
