You can do this by finding the lengths of RT , RS and ST using the distance formula
RT = sqrt ((0- -5)^2 + (4 - -6)^2)
= sqrt (5^2 + 10^2) = sqrt 125
RS = sqrt ((-3- -5)^2 + (-2 - -6)^2))
= sqrt ( 2^2 + 4^2) = sqrt 20
ST = sqrt 125 - sqrt 20
RS / ST = sqrt 20 / (sqrt 125-sqrt 20)
so the ratio RS:ST = 2:3
Its B
Answer:
Bryan is incorrect
Step-by-step explanation:
Let's break it down.
y=-5x+3
the parent function (all variables) is
y=mx+b
where the m is the slope (rate of change)
and the b is the y intercept (initial value)
The x and y are and point on that line
In this case, m=-5 and b=3
Bryan mixed up the variables m and b
The correct answer is that -5 is the rate of change and 3 is the initial value
Answers:
a)
b) 0.299 s
Step-by-step explanation:
a) We are given the following equation:
If we divide by 2 both the numerator and the denominator, we will have:
b) From this equation:
is the reaction time in seconds
is the distance
is the acceleration due gravity
Solving:
This is the reaction time
41 bc it is prime and the ones is 3 less than the 10s
