Using the formulasC=2π r
d=2r
Solving for C:
C=π
d=π·47≈147.65485mm
Answer:
c.
$978.96
Step-by-step explanation:
Answer:
E
Step-by-step explanation:
Since all the numbers are hundredths decimals, let multiply by the power of 2 of the base 10. So let multiply the equation by
So our new equation is
Solve by AC method
We must think of two numbers that
Multiply to -462 and Add to 71. Set up equation
The numbers are 77 and -6.
So our new equation is
Solve by factoring by grouping
Factor out 11 for the first equation
So our factors are
Set each equal to zero
Answer:
Negative
Step-by-step explanation:
The line is trending downwards, which is indicative of a negative slope.
Try this explanation+solution:
1. According to the given graph it is possible to define A - amplitude and B - frequency of this function, then to substitute them to its equation.
2. A=5 (max. and min. values for vertical); B=2 (two periods in the length 2π).
3. answer: y=5sin2x.
