H=-16t^2+46t+6 after how many seconds will the ball hit the ground?
ANEK [815]
Ball hit the ground is when the function equals zero
0=-16t^2+46t+6
we can't factor so use quadraticformula

for
ax^2+bx+c=0
x=\frac{-b+/- \sqrt{b^2-4ac} }{2a}
x=\frac{-46+/- \sqrt{46^2-4(-16)(6)} }{2(-16)}
x=\frac{-46+/- \sqrt{2116+384} }{-32}
x=\frac{-46+/- \sqrt{2500} }{-32}
x=\frac{-46+/- 50 }{-32}
x=\frac{-46+ 50 }{-32} or \frac{-46- 50 }{-32}
x=\frac{4}{-32} or x=\frac{-96}{-32}
x=-1/6 or x=3

we cannot have negative time because time starts at 0
disregard -1/6 as a possible answer


answer is after 3 seconds

Need help I forgot how to do this ​
Marat540 [252]

Answer:

A.

Step-by-step explanation:

you have to find the discriminant

b²-4ac for each equation

if discriminant < 0 no real solutions because will be negative under the squareroot whhan you try to find the roots

if discriminant = 0 there is only one solution

if discriminant > 0 two real solutions

for your given problems

A. discriminant =(-2)²-4*2*15 will be negative

Y=2(x+1)^2 has how many real roots
oee [108]

The equation y= 2(x+1)^2 has one real root and that is x=-1.

What is real roots of the equation?

    We are aware that when we resolve a linear or quadratic equation, we always arrive at the value variable of the equation, or, to put it another way, we always locate the equation's solution. This "solution" is what we refer to as the real roots. For instance, when the equation X^2-7x+12=0 is solved, the actual roots are 3 and 4.

Here given,

=> y = 2(x+1)^2

Take y=0 then,

=> 2(x+1)^2=0

=> (x+1)^2=0

=>(x+1)=0

=> x=-1

Hence the given equation has one real root and that is x=-1.
