Answer:
7
Step-by-step explanation:
Outcomes of the spinner: 2, 3
Outcomes of the die: 1, 2, 3, 4, 5, 6
Add 2 to 1, 2, 3, 4, 5, 6 to get:
3, 4, 5, 6, 7, 8
Add 3 to 1, 2, 3, 4, 5, 6:
4, 5, 6, 7, 8, 9
All different sums:
3, 4, 5, 6, 7, 8, 9
Answer: 7
$126000
Gross salary per month = $10500
Gross salary per annum
= Gross salary per month × 12
= $10500 × 12
= $126000
-√(1 - 2x) + C
1/√(1-2x)
We want to integrate it. Thus;
∫1/√(1 - 2x) dx
Let u = 1 - 2x
Thus;
du/dx = -2
Thus, dx = -½du
Thus,we now have;
-½∫1/√(u) du
By application of power rule, we will now have;
-½∫1/√(u) du = -√(u) + C
Plugging in the value of u, we will have;
5 = |-5|
Think of it as a number line, like in the picture below. The absolute value is how far a number is from zero (0). If 5 is 5 away from zero, then the opposite of 5 (-5) is also 5 away from zero.
Refer to the picture below for an illustration:
