Sole The Equation 0.75q²=108 55 POINTS

1 answer:

5 0

Q= -12

Explain:
Basically we divide both sides by 0.75
Then expand 108 over 0.75 multiplying both by 100 so q cubed= 10800 over 75 when we divide 10800 with 75 we get q cubed=144 then we subtract 144 from each side consider q cubed - 144 rewrite it as q cubed minus 12 cubed the squares can be factored by a cubed and b cubed = ( a - b )(a+b)
So then it’s (q -12) (q+12) = 0 to find solution you gotta solve q - 12 = 0 and q+ 12=0

Answer:

So, L'Hospital's Rule tells us that if we have an indeterminate form 0/0 or ∞/∞ all we need to do is differentiate the numerator and differentiate the denominator and then take the limit. (Brainliest? :3)

If the equation 3x-5y=-3, what is the value of y when x is 1

pantera1 [17]

The answer is: 6/5

Here is why:
3x - 5y = -3
3(1) - 5y = -3
3 - 5y = -3
3 - 5(6/5) = -3
-3 = -3
