An independednt variable is a variable that doesnt need any support Dependent is where there is variable, but it depends on something else.

For example,

y=2x+1

y is dependent, becuase it depend on 2x+1

x is independent, beucase it doesnt need to depend on anything.

Answer:

Lets say that we have an equation. You get 10 dollars for every hour you work. x = how many hours worked, and s = your salary for each hour

<u>example equation</u>
10x = S.

S will be the DEPENDENT variable and X is the INDEPENDENT  variable. Why? Because your salary depends on how many hours you worked. If you work for 5 hours, you get $50. Its not like your boss gives you the $50 and like "work for 5 hours". thats not how it works lol

Hope this helped :)

Find the discriminant<br> 9x^2+14x+13=8x^2
tiny-mole [99]

Answer:

The discrimant of this equation is 144.

Step-by-step explanation:

First you have to move all the variables to one side to make the equation/expression into 0 by substracting 8x² to both sides :

9x² + 14x + 13 = 8x²

9x² + 14x + 13 - 8x² = 8x² - 8x²

x² + 14x + 13 = 0

It is given that the formula of discriminant is, D = b² - 4ac where a&b&c represent the number of the equation, ax²+bx+c = 0 :

x² + 14x + 13 = 0

D = b² - 4ac

= 14² - 4(1)(13)

= 196 - 52

= 144

Please help me with this question thanks. PLEASE I REALLY NEED HELP ON THIS PROBLEM
arlik [135]

Step One

Find the area of the base

A = s * s

s = 755.5 feet

Area = 755.5^2

Area = 570780.25 square feet.


Step two

Multiply the volume by 3

V = 1/3 B * h

3*V = B * h

V = 85600000

85600000 * 3 = B * h

256800000 = B * h


Step Three

Divide by B

B = 570780.25


256800000 = 570780.25 * h

256800000 / 570780.25 = h

449.91 feet = h
