Answer:
Step-by-step explanation:
is our quadratic,where h(t) is the height of the object after t seconds. If we are looking for how long, t, it takes the object to hit the ground, h(t) will be equal to 0 since the height of something on the ground is 0. We set the quadratic equal to zero and factor it using the quadratic formula:
and
and
and
the 2 solutions are:
and
and since time can never be negative, we know that it takes 4.98 seconds for the rock to hit the ground under the given conditions.
Answer:
no
Step-by-step explanation:
Similar triangles have angles with the same measures.
angles in the first triangle are 50°, 60°, 70°.
angles in the second triangle are 50°, 50°, 80°.
The angles do not have the same values, so the triangles cannot be similar.
_____
<em>Comment on the question</em>
When 2 of the three angles are different, the third angle cannot make the triangles similar. We don't even need to compute the third angle to answer this question.
Answer:
g(x) has a greater y intercept than f(x)
Step-by-step explanation:
f(x) = 6x^2 + 18x +3
f(0) = 0+0+3
The y intercept is 3
g(x) crosses the y axis at 6
The y intercept is 6
g(x) has a greater y intercept than f(x)
Just divide the top of the fraction by the bottom, and read off the answer!
