F(x) = 2(x)^2 + 5 * sqrt(x + 2)
f(2) = 2(2)^2 + 5 * sqrt(2 + 2)
f(2) = 2 * 4 + 5 * sqrt(4)
f(2) = 8 + 5 * 2
f(2) = 8 + 10
f(2) = 18
Answer:
After 5 additional days it will be equal
Step-by-step explanation:
1st special: 6x + 50
2nd special: 12x + 20
6x + 50 = 12x + 20
Subtract 20 from both sides;
6x + 30 = 12x
Subtract 6x from both sides;
30 = 6x
Divide both sides by 6;
x = 5
Option B (22,16,18,36)
Mean- Mean is an average of the data collected in the data set. It can be found by dividing the sum of the values by the number of values. Median is the middle value of the data set when the values are placed in order from least to greatest.
It is easy to calculate: add up all the numbers, then divide by how many numbers there are.
Add all the numbers (22+16+18+36) = 92
Avarage = sum of the all given numbers/ total numbers
total numbers =4
so avarage= mean= 92/4 =23
(22,16,18,36) has the most spread because one number as low as 16 and one as high as 36. Our mean is 23, so that means that the spread is huge.
Hence the answer is (22,16,18,36).
