A generator produces voltage using levels of current modeled by I (t) = t +4 where t > 0 represents the time in seconds. The power of the generator can
be modeled by p(t) = 0.26 +8.8t? + 32t. If the voltage is calculated by
dividing P (t) by I (t), what is the expression that represents the voltage of
the generator?

Sorry need points

Step-by-step explanation:

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
