Answer:
x = 10 and y = 10√2.
Step-by-step explanation:
The right triangle has another one angle of 45°.
Therefore, the angles of the right triangle are 90°-45°-45°.
Hence, it is an isosceles right triangle.
Then, the legs of the right angle are equal to be 10.
So, x = 10
Now, the length of the hypotenuse is given by Pythagoras Theorem i.e.
(Hypotenuse)² = 10² + 10²
⇒ y² = 200
⇒ y = 10√2
Therefore, x = 10 and y = 10√2. (Answer)
Answer:
43
Step-by-step explanation:
That is the answer
Demand
D(q)=(12-q)^(1/2)
Revenue,
R(q)=q*D(q)=q*sqrt(12-q)
At maximum revenue,
R'(q)=0
where
R'(q)=sqrt(12-q)-q/[2(sqrt(12-q))]=0
Solve for q=8.
Hence, quantity=8, price=sqrt(12-q)=sqrt(12-8)=sqrt(4)=2
