Answer:
37
Step-by-step explanation:
We start by reducing the ratio to its smallest value. This is the same as 1:14
We know from the question that the number of apple eater takes the 14 ratio part. We can make the calculations for the total number first then make a subtraction to get the number of apple eaters.
Firstly, we add the ratios together:
1 + 14 = 15
Let the total number of reindeers be T
14/15 * T = 517
T = (15 * 517)/14 = 554
To get the the number of apple loving Reindeers, we then subtract.
This is 554 - 517 = 37
Remember
log(a)-log(b)=(log(a))/(log(b))
so
if the base is 10, just ignore it for now
log(60)-log(10)=(log(60))/(log(10))
note that log10=1
(log(60))/(log(10))=(log(60))/(1)=log60
log₁₀60 is answer or log60
C is answer
Answer:
(x - 3)(x - 9i)(x + 9i)
Step-by-step explanation:
note that x = 3 gives
3³ - 3(3)² + 81(3) - 243 = 27 - 27 + 243 - 243 = 0, hence
x = 3 is a root and (x - 3) is a factor
x³ - 3x² + 81x - 243 ÷ (x - 3)
= (x - 3)(x² + 81)
solve x² + 81 = 0 ⇒ x² = - 81 ⇒ x = ± 9i, thus
x³ - 3x² + 81x - 243 = (x - 3)(x - 9i)(x + 9i) ← in factored form
