Answer:
A
Step-by-step explanation:
Given the exponential function
f(t) = 228
← where t is time in years
Substitute t = 20 into f(t), that is
f(20) = 228 ×
= 228 × 0.60268.... ≈ 137 → A
Answer:
16/33
Step-by-step explanation:
The probability that the first ball is red and the second ball is black is:
8/12 × 4/11 = 8/33
The probability that the first ball is black and the second ball is red is:
4/12 × 8/11 = 8/33
So the total probability of drawing one ball of each color is 8/33 + 8/33 = 16/33.
It is 135cm squared please give me brainliest

The explicit formula for an arithmetic sequence is an = a1 + d(n - 1) where a1 is the first term and d = common difference. For this sequence a1 is 7 and d = 13- 7 = 19 - 13 = 25 - 19 = 6
So explicit formula required = 7 + 6(n - 1)
