Answer:
This is a true statement. I think that's what you're asking.
Step-by-step explanation:
It is true because if x=y, than 6x=6y because both sides have a 6 and x=y
It should be 9:30 P.M.
7:45+ 15= 8
1 hour 35 minutes - 15= 1 hour 20
8+ 1 hour 20 minutes= 9:20
9:20+ 10= 9:30 P.M.
Answer:
90⁰
Step-by-step explanation:
y=cosx
y'= -sinx
eqñ of tangent is y=-x
slope of tangent =-1
we know...
slope of tangent = y' or derivative of y
-sin x = -1
sin x= 1
x = 90⁰
Answer:
a. 1 hour and 32 minutes b. 8:07
Step-by-step explanation:
a.8:34-7:02
b. 9 minutes +1 hour and 32 minutes+12 minutes=1.53 hours before 10=8:07
Answer:
14.52 seconds.
Step-by-step explanation:
We have been given that the height of the rocket, y in feet, is related to the time after launch, x in seconds, by the given equation
. We are asked to find the time, when the rocket will hit the ground.
We know that the rocket will hit the ground, when height will be 0. So to find the time when rocket will hit the ground, we will substitute
in our given equation as:

Let us solve for x using quadratic formula.








Upon rounding to nearest 100th of second, we will get:

Since time cannot be negative, therefore, the rocket will hit the ground after 14.52 seconds.
