Which graph represents an exponential function? A: On a coordinate plane, a curve decreases rapidly and then levels out.
B: On a coordinate plane, a curve decreases, changes directions, and then decreases again.
C: On a coordinate plane, 2 curves mirror each other.
D: On a coordinate plane, a line curves increases gradually.

answer: 0+0=0

step-by-step explanation:

that is the only answer that can make 0

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

probability for j is 1/4

while

a is 1/6
