Answer:
x = 50
R = $2500
Step-by-step explanation:
Given in the question a quadratic equation,
−x² + 100x
To find the selling price, x, which will give highest revenue, y, we will find maximum value of parabola curve −x² + 100x
The value of -b/2a tells you the value x of the vertex of the function
−x² + 100x
here a = -1
b = 100
Selling price = -(100)/2(-1)
= 50
R = −(50)² + 100(50)
= 2500
Answer:


Step-by-step explanation:
Given the matrices


Calculating AB:

Multiply the rows of the first matrix by the columns of the second matrix


Hence,

Therefore,


Answer:
A
Step-by-step explanation:
Yes ! I can help you.
-- Take each fraction.
-- Do the division . . . (top number) divided by (bottom number) .
-- Write the whole number from the quotient.
Save the remainder.
-- After the whole number, write a fraction.
Copy the original bottom number to the bottom of the fraction.
-- Copy the remainder from the division to the top of the fraction.
Bada-bing ! There's your mixed number.
