Answer:

\sqrt{a^2+b^2} which is the absolute value of complex plane |a+ib|

Step-by-step explanation:

The absolute value of any complex number is its modulus for which we have a formula of modulus

\sqrt{a^2+b^2} where a and b are real numbers.

Please look at the attachement for complex plane of the given points (a,b) and (0,0)

The distance between two points (x_1,y_1) and (x_2,y_2)] will be

\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Here we need to find the distance between (a,b) and (0,0)

on substituting the values in distance formula we will get

\sqrt{(0-a)^2+(0-b)^2}

\Rightarrow\sqrt{a^2+b^2} which is the absolute value of complex plane |a+ib|

The blueberries in the farmer's market costs less than the blueberries from the grocery store. 

One pound of blueberries from the farmer's market is cheaper by $0.80 than the blueberries from the grocery store. ($5.60 - $4.80 = $0.80)

The cost function for a certain company is C = 20x + 700 and the revenue is given by R = 100x − 0.5x2. Recall that profit is rev
Brilliant_brown [7]

Answer:

x = 20

x = 140

Step-by-step explanation:

Find the equation for profit P

P = R - C

Substitute the equations for R and C then simplify.

P = 100x − 0.5x² - (20x + 700)

P = -0.5x² + 80x - 700

Find the values of x when profit is $700

P = -0.5x² + 80x - 700

700 = -0.5x² + 80x - 700

0 = -0.5x² + 80x - 1400

This is in the standard form 0 = ax² + bx + c

Use the quadratic formula to find values of x

x = \frac{-b±\sqrt{b^{2}-4ac}  }{2a}

(Ignore Â)

Substitute a b and c.

a = -0.5

b = 80

c = -1400

x = \frac{-(80)±\sqrt{80^{2}-4(-0.5)(-1400)}  }{2(-0.5)}

x = \frac{-80±60}{-1}

Split the formula at the ± so that there are two to get the two x values.

x = \frac{-80+60}{-1}

x = \frac{-80-60}{-1}

x = 20

x = 140

The profit will be $700 when x is 20 or when x is 140.

earnstyle [38]
<h2>Answer:</h2>

<u>The correct option is </u><u>The letter on the front will be N. The letter on the back will be L. </u>

<h2>Step-by-step explanation:</h2>

When we fold the given net, we will get Q,P,M and N on sides. Side M will come to the top, side Q on the right side, side P on the left and side O on the bottom. The side which comes to the front will  be N of the observer and similarly the side L will come to the back of the rectangular prism.
