Answer:
{2.96, 12.66}
Step-by-step explanation:
A graph shows the rocket will be 600 feet up after 2.96 seconds, and again at 12.66 seconds.
__
You can solve the equation h = 600 to find the times.
-16t^2 +250t = 600
-16(t^2 -15.625t) = 600
-16(t^2 -15.625t +7.8125²) = 600 -16(7.8125²)
-16(t -7.8125)² = -376.5625
t -7.8125 = √(376.5625/16) ≈ ±4.8513
t = 7.8125 ± 4.8513 ≈ {2.9612, 12.6638}
The rocket will be 600 ft above the ground 2.96 and 12.66 seconds after launch.
Answer: y=2x-1
Step-by-step explanation:
Equation of a line that passes through (a,b) and have slope m is given by :-
[point slope form]
Given, Point = (4,7) , m= 2
Equation in point slope form :
To write in slope intercept form (y=mx+c) , we need to simplify it
Hence, y=2x-1
For this case we make a rule of three:
jar --------------->
pizza
x -----------------------------------------> 1 pizza
Where the variable "x" represents the amount of sauce jars to make a pizza.
So, you need jars of sauce to make a pizza.
