If we let x be the speed of the boat you are taking to the island (the steamboat), then we know that the speed of the other boat (the tall ship) is 10 knots less than the steamboat's. So the speed of the tall ship (for the return trip) is (x - 10) knots.
Answer:
(14/3)a - (3/2) units²
Step-by-step explanation:
Integrate the function
a(x^0.5) - 2(x^-2)
Add 1 to the power, divide by the new power
a(x^1.5)/1.5 - 2(x^-1)/-1
(2a/3)(x^1.5) + 2/x
Upper limit - Lower limit
[(2a/3)(4^1.5) + 2/4] - [(2a/3)(1^1.5) + 2/1]
= [16a/3 + 1/2] - [2a/3 + 2]
= 14a/3 - 3/2
= (14/3)a - (3/2) units²
Answer:
OPTION A
OPTION B
OPTION C
Step-by-step explanation:
Irrational numbers are the subset of real numbers. Their decimal representation neither form a pattern nor terminate.
OPTION A: 
This is equal to 
.
is non-terminating. So, it is an irrational number. Hence, the reciprocal of an irrational number would also be irrational. So, OPTION A is irrational.
OPTION B: 
This is equal to 
. Using the same logic as Option A, we regard OPTION B to be irrational as well.
OPTION C: 
This is equal to 
.
Both 
and 
are irrational. So, the product and the reciprocal of the product is irrational as well. So, OPTION C is an irrational number.
OPTION D: 
16 is a perfect square and is a rational number. 
= 
. This is equal to 0.25, a terminating decimal. So, OPTION D is a rational number.
OPTION E: 
4 is a perfect square as well. 
, a terminating decimal. So, OPTION E is a rational number.
Answer:
5
Step-by-step explanation:
5 - 10 = -5
-5 - (-10) = 5
