Answer:
The domain is the interval [5,∞)
Step-by-step explanation:
we have

we know that
The radicand (number under a radical) must be greater than or equal to zero
so

solve for x
Adds 5 both sides


therefore
The domain is the interval [5,∞)
All real numbers greater than or equal to 5
Answer:
Step-by-step explanation:
a)
The mistaken assumption is that Apple spends "far less" on Research and Development than any of its rivals.
b)
The assumption is incorrect because it took cognizance of the percentage used, and not the actual money spent. In truth, Apple generates far more income than the other two rivals. With Apple generating over $100bn in the said time span, and Google generating $37bn. At the end of the day, Apple spends $2.1bn on Research and Development, while Google spends $5.3bn on the same. This is quite close than the quoted distance of 14% - 2%
c)
Yes, I think so. But only when the 3 companies generate almost the same revenue.
B = block p = park
2b + p = 10 min 2 runs around the block takes 10 minutes
2b + 3p = 22 min 2 runs around the block plus 3 runs around the park takes 22 minutes
To solve, I will use substitution. First, I will divide the first equation by 2 to get b by itself and subtract p from both sides to get b by itself. Then, substitute 5 - 1/2p in for b in the second equation because they have equal values. Then, subtract 10 from both sides to eliminate it. Divide by 2 to both sides to get 'p' by itself.
2b + p = 10 min ---------→b + 1/2p = 5 ----------→ b = 5 - 1/2p
2(5 - 1/2p) + 3p = 22 ---------→ 10 -p + 3p = 22 --------→ 10 + 2p = 22
10 + 3p = 22 ----------→ 2p = 12
2p = 12 -------------→ p = 6
It takes 6 minutes to jog around the park
Hope this helps!
Answer:
385 counters
Step-by-step explanation:
Since 1/6 of the counters are red and 1/4 of the counters are blue, there are:
1 - (1 / 6) - (1 / 4) = 7 / 12
Multiply it to find green:
660 x (7 / 12) = 385 counters
Answer:
The true statement is: The probability that a randomly selected player on Team C is 10 years old is
.
Step-by-step explanation:
According to the table the total number of 10 years old players on Team C is 5 and the total number of all ages players (8, 9 and 10 years old) on Team C is 16, so the probability that a randomly selected player on Team C is 10 years old is 5/16.
