Answer:
√7i = x
Step-by-step explanation:
x²+y²=9;
y² = 9-x²
y = √(9-x²)
As line is given by y= 4, the solution of the system is:
4 = √(9-x²)
16 = 9-x²
7 = -x²
-7 = x²
√-7 = x
As √-7 doen't exist, you should use i = √-1;
Thus,
<em>√7i = x</em>
<em></em>

Answer:
666.667
Step-by-step explanation:
One ton weighs 2,000 lbs, so you divide 2,000 by 3.
The second one and the last one
So you start with
V = <span>πr^2h
</span>you divide both sides by <span>πr^2
(v/</span><span>πr^2) = h</span>
Answer:
a. 10
b. 0.1
Step-by-step explanation:
a. The t-shirts comes in 5 sizes (Small,medium,large, extra large and extra extra large) and two colors orange and black. The total different type of shirts are 5*2=10 different type of t-shirts.Also if we make sample space of all shirts we can assess the total different type of t-shirts. sample space=S={small orange,medium orange,large orange,XL orange,XXL orange,small black,medium black,large black,XL black,XXL black}. n(S)=total different type of shirts=10.
b. P( large orange t-shirt)=n(large orange t-shirt)/n(S)=1/10=0.10.
