Answer:
31/40
Step-by-step explanation:
Given expression:
Note: Both fractions must have same denominators if we want to perform addition, subtraction, multiplication, or division.
The only way to simplify this expression is to have a common denominator, which can be determined by the LCM of 5 and 8.
- ⇒ Multiples of 5: 5, 10, 15, 20, 25, 30, 35, 40, 45...
- ⇒ Multiples of 8: 8, 16, 24, 32, 40, 48, 56, 64, 72...
Multiply the denominators with such a number that is equivalent to 40.
Note: The number you are multiplying should also be multiplied to the numerator.
Finally, simplify the expression to determine the solution.
Since 31 is a prime number, we can't simplify this fraction. Thus, the final answer is 31/40.
Answer:
F(0) = 0
F(1) = 3
F(2) = 2 x F(1) + F(0) = 2 x 3 + 0 = 6
F(3) = 3 x F(2) + F(1) = 3 x 6 + 3 = 21
F(4) = 4 x F(3) + F(2) = 4 x 21 + 6 =90
F(5) = 5 x F(4) + F(3) = 5 x 90 + 21 = 471
Hope this helps!

Answer:
f(1) = 257
Step-by-step explanation:
x-variable: 1 (time is the independent variable)
y-variable: 257 (number of visitors is the dependent variable)
When the time is at 1 (1pm), there are 257 visitors
Given:
The measure of three sides of a triangle are 8, 7 and 14.
To find:
The measure of the angle opposite the side of length 8.
Solution:
According to the Law of Cosine:
Let a=8, b=7 and c=14, then by using Law of Cosine, we get
Taking cos inverse on both sides.
Therefore, the measure of the angle opposite the side of length 8 is 22.6 degrees.
