The other solution to the equation is -3.
Step-by-step explanation:
Given equation is;
5x²+bx+12=0
One solution is -4/5
We will put this solution in Eqn to get the value of b first,

Multiplying each term by 5

Dividing both sides by -4

Putting b=19 in given Eqn
5x²+19x+12=0
Here,
a=5 , b=19 , c=12
Using quadratic formula,

Either, or,

The other solution to the equation is -3.

The equation is <span>h(t) = -16t2 + 1600</span>.
When the package hits the ground, h(t) = 0: 0 = -16t2 + 1600 To solve by factoring: 0 = -16(t2-100)0 = -16(t+10)(t-10) t = -10 and +10 seconds.
Since we aren't interested in negative time, t = 10 seconds.
So for every hour they make 21.70 I’m not sure if that’s how constant of proportionality works since I never learned that sorry
