Answer:
=10x2−8
Step-by-step explanation:
4(x2−5)+2(3x2+6)
Distribute:
=(4)(x2)+(4)(−5)+(2)(3x2)+(2)(6)
=4x2+−20+6x2+12
Combine Like Terms:
=4x2+−20+6x2+12
=(4x2+6x2)+(−20+12)
=10x2+−8
I'll do it with a fraction, so let's say 15/45. 15 of the cards are baseball cards, 30 of them are other cards. I would say 15/45, because 45 is the total amount of the cards he has. Only 15 are BASEBALL cards, so it would make sense to say he has a 15/45 chance to pull a baseball card.
Answer:
Step-by-step explanation:
If n(t) represents the population size at time t, where n is measured in individuals and t is measured in years.
Taking the integral of both sides
ln |n| = 
Where C is integration constant
Taking the exponential of both sides
whee the exponential of a constant is a constant K.
When t=0, 
Therefore:
Answer:
A = 169π/4
Step-by-step explanation:
From these two given points we find the length of the diameter of this circle, using the Pythagorean Theorem:
d^2 = (8 - 3)^2 + (13 - 1)^2, or
d^2 = 25 + 144 = 169
Thus, the diameter, d, of this circle is √169, or 13.
The radius is thus 13/2 units.
The area formula is A = πr^2. Here the area is
A = π(169/4), or A = 169π/4
