B) 6 seconds
C) 1.5 seconds
D) 3 seconds
So this question is asking for the zeros, or the x-intercepts, of this equation. For this, we have to set h(t) to zero to solve for it.
For this, we will be using the quadratic formula, which is (a = t^2 coefficient, b = t coefficient, and c = constant). In this case, our equation is . From here we can solve for t.
Since we cannot have negative time,the object hits the ground at 3 seconds, or D.
Answer:
x = 1.36
Step-by-step explanation:
To solve the equation '5(x-2 2/5)=-5.2', distribute the 5 across the (x-2 2/5) term, add 11 to each side, then divide by 5. This gives us x = 1.16.
The question is asking us to solve the equation 5(x-2 2/5)=-5.2 for x. To do this, we follow several steps:
Hence the solution to the equation is x = 1.16.
