Fireworks are set off from a hill 80 feet above the Mississippi. The outer
shells will fall after exploding at its maximum height. The firework's height
about the surface of the river is given by the function h(t) = -16t^2 + 64t +
80. What is the height of the rocket after 1.5 seconds?
Answer:
752 ft
Step-by-step explanation:
Assuming t represents time, and the time we are trying to find is how high the rockets go after 1.5 seconds, we must take the equation and put 1.5 in wherever t occurs, this looks like:
-16(1.5)²+64(1.5)+80
solving this, we get:
-24²+96+80
576+96+80
752

Question # 1 : If Question # 2 : How are lines, rays, and segments different? How are they the same?
Answer:
A line segment has two endpoints. It contains these endpoints and all the points of the line between them. A segment is named by its two endpoints. A ray is a part of a line that has one endpoint and goes on infinitely in only one direction. You cannot measure the length of a ray.

why do systems of nonlinear equations sometimes have more than one solution
Answer:
System has equal number of unknowns and equations.
Manipulation easily yielded expressions for 4 of the 7 unknowns.
However it seems that the remaining 3 unknowns x,y,z are not fixed by the equations. Different combinations (x0,y0,z0) seem possible without violating the system equations.
Is this possible, or did I most probably make a mistake in counting degrees of freedom?

You now have a lot of experience working with equations that compare two quantities. For example, while working with the height of a tree, you found the
relationship y = 41+5. which compared 2 (the number of years after it was planted) with y (its height in feet). Use the equation for this tree to answer the
questions below
a. What was its starting height? How can you tell from the equation?
Answer:
If you mean y = 4x + 5, then the answer is 5 (the height would be 5 feet)

What are the zeros of f(x) = x2 + x - 12?
O A. x= -4 and x = 3
O B. x=-2 and x = 6
O C. =-3 and x = 4
O D. X=-6 and x = 2
Answer:
(x+4)(x-3) or A
Step-by-step explanation:
I'm going to assume that you meant to write x² and not x2
which means we have
x²+x-12
and we need to factor this
to do this we need two numbers that add up to 1 (b) but mulitply to -12 (a*c)
our two numbers are
4, -3
Which means the answer is
(x+4)(x-3)
