Choose the answer. find the product. -1/2 • ( - 8)
a. -16
b. -4
c. 4
d. 16

C. 4

Step-by-step explanation:

-1/2 * (-8)

Replace -8 with a fraction

-1/2 * -8/1

Multiply the numerators

-1 * -8 = 8

Multiply the denominators

2*1 =2

Put the numerator over the denominator

8/2 = 4

0.02

step-by-step explanation:

time of 9 192 631 770 periods of the radiation corresponding to the transition between the 2 hyperfine levels of the ground state of the caesium 133 atom at 0 k (but other seconds are sometimes used in astronomy)

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.
