I= sqrt (-1)
If the power is
- even then the value could be -1 or 1
-odd then the value could be -i or i
99 is odd so now is
-i if (99+1)/2 is even or is
i is (99+1)/2 is odd
Now check (99+1)/2= 100/2= 50,
50 is even so
i^99 = -i
Answer:
39.9 grees
Step-by-step explanation:
Since 4.2 kribs = 18 grees
Then,
1 krib = 18/4.2 grees
9.3 kribs = (18/4.2) x 9 3
9.3 kribs = 39.9 grees.
Answer:
<h2>
b) y = -3x - 7</h2>
Step-by-step explanation:
3x + y = 5 {subtract 3x from both sides}
y = -3x + 5 ← slope-intercept form
y=m₁x+b₁ ║ y=m₂x+b₂ ⇔ m₁ = m₂
{Two lines are parallel if their slopes are equal}
y = -3x + 5 ⇒ m₁ = -3 ⇒ m₂ = -3
(-1, -4) ⇒ x₁ = -1, y₁ = -4
The point-slope form:
y - (-4) = -3(x - (-1))
y + 4 = -3(x + 1)
y + 4 = -3x - 3 {subtact 4 from both sides}

<u>y = -3x - 7 </u><u> ← slope-intercept form</u></h3>
Answer:
The average number of customers per day during the sale was 150.
Step-by-step explanation:
This question can be solved using a rule of three.
Before the sale, the average number of customers per day was 120, which is 100% = 1.
Now, there are x customers, and since it is an increase of 25%, it is 100+25 = 125% = 1.25. So
120 - 1
x - 1.25
x = 1.25*120 = 150
The average number of customers per day during the sale was 150.
