Answer:
Part A: This can be solved using cancellation of units: Energy produced (ergs) = (3.9 x 10^ 33 ergs/ sec)( 1.55 x 10^7 sec) = 6.045 x 10^40 ergs Part B: The grooves within a CD is very small, therefore it would be more reasonable to have a value of 1.6 x 10^-3 mm

Answer:
each movie costs $2.75, each video game costs $6.75
Step-by-step explanation:
x = movies, y = video games
7x + 9y = 80
5x + 3y = 34
simplified to
x = 11/4 , y = 27/4
Answer:
C. 4
Step-by-step explanation:
Hi, the number of sample points is the sum of all attempts you executed during an experiment. Because the experiment proposes tossing a coin 4 times, then you have 4 sample points.
Attempt 1 = coin toss 1 = sample point 1
Attempt 2 = coin toss 2 = sample point 2
Attempt 3 = coin toss 3 = sample point 3
Attempt 4 = coin toss 4 = sample point 4
Step-by-step explanation:
The general form of the quadratic equation is :

The given equation is x²+4x+20=0
On comparing the given equation and the general equation, we find that
a = 1, b = 4 and c = 20
Hence, the correct option is a=1 b =4 c = 20.
If the equation is 2x²+6x+5=0, then
a = 2, b = 6 and c = 5
If the equation is -2x²+x+5
a = -2, b = 1 and c = 5
