Step-by-step explanation:
A rocket is launched from a tower. The height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation. Using this equation, find the time that the rocket will hit the ground, to the nearest 100th of second. y=-16x^2+157x+124 y=−16x 2 +157x+124
Answers
Answer:
Rocket will hit the ground in 10.55 seconds.
Step-by-step explanation:
Let be [tex]y = -16\cdot x^{2}+157\cdot x +124[/tex], where [tex]x[/tex] and [tex]y[/tex] are time after launch and the height of the rocket, measured in seconds and meters, respectively. To find the time that the rocket will hit the ground, we need to equalize height to zero and solve the resulting expression:
[tex]-16\cdot x^{2}+157\cdot x + 124 = 0[/tex]
The quadratic function can be solved analitically by Quadratic Formula, that is to say:
[tex]x = \frac{-157\pm \sqrt{157^{2}-4\cdot (-16)\cdot (124)}}{2\cdot (-16)}[/tex]
Roots of the polynomial are, respectively:
[tex]x_{1} \approx 10.55\,s[/tex], [tex]x_{2}\approx -0.74\,s[/tex]
Only first root offers to us a reasonable solution. Hence, we conclude that rocket will hit the ground in 10.55 seconds.

If the sum of the square of the number and 4 time the number is 21,
what is the number?
Answers
Answer:
I think there is a missing “and” there: “If the sum of the square of the number and 4 times the number is 21, what is the number?”
If so, then we have: x² + 4x = 21, or x² + 4x - 21 = 0.
This factors as (x+7)(x-3) = 0, so x = -7 or x = 3.

E. People once thought animals were individually create by some superior.
But the solid creation of theory of origin of species by the naturalist Charles Darwin demonstrated a different theory.
Step-by-step explanation:
Before Charles Darwin several scientists were discussing the hypothesis of a theory of evolution. But it was Darwin whom put together all the information with reliable explanation and correlation between animal specialization and environment accordyinly with time.
He spent almost five years on board the ship HMS Beagle, crossing several continents, starting with South America. From there, he returned with dozens of specimens of living species, illustrations and fossils. Those specimens helped Darwin in his discoveries which originated the book On the Origin of Species published in 1859.
