Alexxx [7]3 years ago

The Law of Cosines is used for this purpose.
  c² = a² + b² - 2ab·cos(C)
  c² = 5² + 4² - 2·5·4·cos(60°)
  c² = 25 + 16 - 20 = 21
  c = √21

The length of side c is √21 ≈ 4.583.

_____
If you really intend the side lengths to be 55 and 44, your result is c≈50.408, the above value times 11.

Let f(x)= log x
marshall27 [118]

Answer:

The average rate of change of f(x) from 2-3 is 0.176

Step-by-step explanation:

Rate of change= change in y / change in x

                        = log 3 - log 2 / 3-2

                        = 0.477-0.301 / 1

                        = 0.176

emily leaves her house at exactly 8:25 am to bike to her school, which is 3.42 miles away. when she passes the post office, whic
NNADVOKAT [17]
We first calculate Emily's rate by dividing the distance from her home to the post office by the time it took her to travel that distance. From 8:25 to 8:29 (and 30 seconds), there are exactly 4.5 minutes. Thus, the rate is equal to,
                                   r = (0.75 miles) / (4.5 minutes) = 1/6 miles/min
Then, we divide the given distance from her home to school by the calculate rate to determine the total number of minutes it will take her to travel to school.
                               t = (3.42 miles)/(1/6 miles/min) = 20.52 minutes
Adding this to 8:25 will give us an answer of 8:45 and 31.2 seconds. She will not be late.

A bit is a 0 or a 1. a bit string is a sequence of digits, all of which are either 0 or 1. for example, there are 8 possible bit
Kipish [7]
For a string length of 1 there are 2 possible strings (2^1)
for a string length of 2 there are 4 possible strings (2^2)
for a string length of 3 there are 8 possible strings (2^3)
So, for string length of 7 there are 128 possible strings (2^7)
