Answer:
The right answer is option (c) -1,300
Parameterize the part of the surface we care about, denoted 
, by
with 
and 
.
Then
The area is given by the surface integral
P = 2(L + W)
P = 2(6.82 + 9.35)
P = 2(16.17)
P = 32.32 meters <==
Answer:
0.00094
Step-by-step explanation:
Scientific Notation is a shortened form of writing a number using exponents. It has the following rules:
- Use a positive exponent for large numbers greater than 1.
- Use a negative exponent for small numbers less than 1.
- Always write the first number as a value between 0 and 9.
9.4 x 10^-4 has a negative exponent and will be a number smaller than 1. This means 0.00094 and 0.0094 are options. Now count from the decimal in each to the space between 9 and 4. In the first it is 4. In the second it is 3. Since the exponent is -4, this means 0.00094 is the solution.
Median is the number in the middle when all the numbers are put in order.
Let's do that first.
30 52 61 65 68 68 69 75 78 85
Now if there's 10 numbers, 2 numbers are in the middle.
By counting in 4 on both sides, we know the two numbers are both 68, so 68 is the median.
