Answer: <em>уравнение имеет 2 решения:</em>
<em> x₁ = - 4; x₂ = - 2.</em>
Step-by-step explanation:
<em>Ix + 3I = 1</em>
<em>1) x + 3 = 1</em>
<em> x + 3 - 3 = 1 - 3</em>
<em> x = -2</em>
<em>2) - (x + 3) = 1</em>
<em> x + 3 = - 1</em>
<em> x + 3 - 3 = - 1 - 3</em>
<em> x = - 4</em>
Area of a circle is PI x r^2:
Area of circle = 3.14 x 13^2 = 530.66 square meters.
To find the area of the sector multiply the area of the circle by the fraction of the sector
Area of sector = 530.66 x 150/360 = 221.108 square meters ( Round the answer as needed).
Answer:
4 + (2 + 1)2 = 4 + (3)2 = 4 + 9 = 13
$37,500 profit
To solve this, find the unit rate by dividing 2500 by 20. This will get you an average of $125 profit made per product sold. Then multiply that by 300 (the number of products sold in total) to get your answer of $37,500 profit total.
