Answer:
C. 2.5×10^-27
Step-by-step explanation:
(2×10^-13)^-2 = 2^-2 × 10^(13×(-2)) = 1/4 × 10^-26
= 0.25 × 10^-26 = 2.5 × 10^-27
___
Your scientific or graphing calculator can compute and display this for you.
Answer:



Step-by-step explanation:
= (probability of entire face value paid*face value+probability of entire face value not paid*percent of face value paid*face value)/(1+discount rate)^years to maturity
probability of entire face value paid = 75%
face value = 1000
probability of entire face value not paid = 25%
percent of face value paid= 60%
discount rate = 15%
years to maturity = 3



Answer: The number is 12.
Step-by-step explanation:
Since we have given that
Sum of two digits = 12
Let the one's digit be 'x'
Let the ten's digit be '12-x'
So, Original number would be

If 16 is added to the number, then one of the digit is four times the value of the other.
According to question, we get that

so, the one's digit be 'x'.
Let the ten's digit be '4x'.
so, New number would be

According to question, it becomes,

So, the number would be

Hence, the number is 12.
The goal is to solve for y. Start by subtracting 2x from both sides. This gives you 8y=-2x+16. Now just divide both sides by 8, which gives you y=-2/8x+16/8. Finally, simplify this to y=-1/4x+2.
