Ok
y=-0.04x^2+8.3x+4.3
when the rocket reaches the ground (when height=0, ie when y=0), then the rocket will land, find the x coordinate
set y=0
0=-0.04x^2+8.3x+4.3
use quadratic formula
if you have ax^2+bx+c=0, then
x=
a=-0.04
b=8.3
c=4.3
x=
x=208.017 or -0.516785
xrepresents horizontal distance
you cannot have a negative horizontal distance unless you fired and theh wind blew it backwards
therefor x=280.017 is the answer
208.02 m

4x _ 8 + 90 = 144
Step-by-step explanation:
you do parentheses then the rest you follow that order and it will all work ot really easy
Triangular
I think that it
Answer:
20 square units
Step-by-step explanation:
The area of a parallelogram is the product of its base length and the height measured perpendicular to the base.
Here, the base is 5 units and the height is 4 units. These can be seen by counting the grid squares.
A = bh
A = (5 units)(4 units) = 20 units²
The area is 20 square units.
Select the correct answer. What is the mode of this data set? {41, 43, 45, 3, 11, 23, 24, 27, 29, 45, 12, 19, 22, 49, 25}
