Sqrt -13 = sqrt13 i
sqrt -26 = sqrt2 * sqrt13i
sqrt-13 * sqrt -26 = sqrt2 * 13* i^2 = -13 sqrt2 (because i^2 = -1)
answer is -13 sqrt2
Answer:
This is a group specific influence sample, it only shows a demographic sample of those that are influenced by the reviews in the first place.
Step-by-step explanation:
The temperature drops 2 degrees in x hours, we could write it as

Answer:</h2><h2>
Roger's profit = %0.5 (I) - $7</h2><h2>
The minimum number of cups of lemonade you have to sell in order to make a profit = 15</h2>
Step-by-step explanation:
Roger spends $7 to buy supplies for making lemonade.
Cost price = $7
He plans to sell each cup of lemonade for $0.50.
Selling price of one cup of lemonade = $ 0.5
Selling price of I cups = $0.5 (I)
(i) The equation that repesents profit earned by Roger is
Profit = Selling price - cost price
Profit = %0.5 (I) - $7
(ii) the minimum number of cups of lemonade you have to sell in order to make a profit is
By selling minimum 15 cups, the profit earned is
Profit = %0.5 (15) - $7
Profit = $0.5
