If the demand function for a commodity is given by the equation
Margarita [4]

Answer:

Equilibrium quantity = 26.92

Equilibrium price is $31.13

Step-by-step explanation:

Given :Demand function : p^2 + 16q = 1400

           Supply function : 700 -p^2 + 10q = 0

To Find : find the equilibrium quantity and equilibrium price.

Solution:

Demand function : p^2 + 16q = 1400  --A

Supply function : p^2-10q=700 ---B

Now to find the equilibrium quantity and equilibrium price.

Solve A and B

Subtract B from A

p^2-10q -p^2-16q=700-1400

-26q=-700

26q=700

q=\frac{700}{26}

q=26.92

So, equilibrium quantity = 26.92

Substitute the value of q in A

p^2 + 16(26.92) = 1400

p^2 + 430.72 = 1400

p^2 = 1400- 430.72

p^2 = 969.28

p = \sqrt{969.28}

p = 31.13

So, equilibrium price is $31.13

What is the length of the unknown leg in the right triangle? 6 mm 8 mm mm mm
makkiz [27]

Answer: 10mm

Step-by-step explanation: You are going to use the "Pythagorean Theorem" method.

Step 1 :

Equation : a^2+b^2=c^2

plug in your data to the equation given. Then simplify and add.

6^2+8^2=C^2

simplify : 36 + 64 = C^2

simplify : 100 = C^2

Step 2 :

Find what goes into 100 evenly.

100 = 10^2 = (10)(10) = C^2

Step 3:

Find the square root of 10^2 = C^2

10 = c

Last Step :

The length of the unknown leg in the right triangle is 10mm

YAY!!!! you're finished! I hope I explained this so it was easy for you to understand.
