solve each equation by finding square roots. If the equation has no real number solution, write no solution. 64b^2=16

4x+2x^2+3x-2x+7
First, you would combine like terms. In this case, you would add 4x and 3x then subtract 2x.
2x^2+5x+7

5x^2-2x+3+4x-2x^2
Once again, you must combine like terms. Subtract 2x^2 from 5x^2, then subtract 2x from 4x.
3x^2+2x+3

There you go! Hope it helps

Two cyclists , A and B , are going on a bike ride and are meeting at an orchard . They left home at the same time . Functions A

vova2212 [387]

Answer:

Cyclist A lives farther from the Orchard

Step-by-step explanation:

Given

$A(x) =48.5 -21x$

$B(x) =42 -16.8x$

Required:

Who lives farther from the Orchard.

To do this, we simply calculate the y intercept.

This represents the total distance traveled to get to the Orchard

To calculate y intercept, we set $x = 0$

So:

$A(x) =48.5 -21x$

$A(0) = 48.5-21*0 =48.5-0 =48.5$

$B(x) =42 -16.8x$

$B(0) = 42 - 16.8*0 =42-0 =42$

From the above computation:

$A(0) > B(0) \to 48.5 > 42$

Hence;

Cyclist A lives farther from the Orchard

What would be the total cost, both fixed and variable, at an activity level of 7,100 units? Assume that this level of activity i

monitta

Answer:

TC = $971,919

Step-by-step explanation:

Given complete question is as follows:

" Cooke Corporation reports that at an activity level of 7,000 units, the total variable cost is $590,730, and the total fixed cost is $372,750.

What would be the total cost, both fixed and variable, at an activity level of 7,100 units? Assume that this level of activity is within the relevant range."

Solution:

- The total cost (TC) is the sum of the fixed cost (FC) and variable cost (VC):

TC = FC + VC

- The fixed cost remains constant at every unit level i.e [email protected],000 = [email protected],100 = $372,750.

- The variable cost VC is a linear function of number of units. The marginal variable cost (MVC) is:

MVC = VC / numbe of units

MVC = 590,730 / 7000

MVC = $84.39/units

- The VC cost @7,100 units is as follows:

[email protected],100 = [email protected],000 + MVC*( 7,100 - 7,000)

[email protected],100 = $590,730 + $84.39/units*( 100 )

[email protected],100 = $590,730 + $8439

[email protected],100 = $599,169

- The total cost for 7,100 units is:

TC = FC + VC

TC = $372,750 + $599,169

TC = $971,919

You want to study how the number of popped kernels in a microwave popcorn bag is affected by brand, microwave power, and time in

Afina-wow [57]

Answer:

Number of unique treatment combinations = 8

Step-by-step explanation:

Given:

Number of brands = 3

Number of power settings = 2

Number of microwave times = 3

Find:

Number of unique treatment combinations.

Computation:

Number of unique treatment combinations = Number of brands + Number of power settings + Number of microwave times

Number of unique treatment combinations = 3 + 2 + 3

Number of unique treatment combinations = 8
