As you said it was dropped so in that case I'll take 78.4 meters as the height..
we know that
h = ut + 0.5*g*t(sqr)
t(sqr) = 78.4/(0.5*9.8) [g = 9.8 ms-2]
t = √16
t = 4
So it'd take 4 seconds
Answer: A) The x-intercept decreases.
Step-by-step explanation:
Hi, for the function f(x) = mx + b, if the value of b decreases, but the value of m remains the same, The x-intercept decreases.
For example
For b=2, m =1 and x =0 (since the y-value of a linear equation when it crosses the x-axis is 0 )
f(x) =0(1)+2 =2 (x-intercept)
For b= 1 (b decrease)
,m =1 and x =0
F(x) = 0(1) +1 = 1 (x_intercept also decreases)
So, the correct option is A) The x-intercept decreases.
Feel free to ask for more if needed or if you did not understand something.
Answer:
-4/5
Step-by-step explanation:
slope = m = (difference in y)/(difference in x) = (-3 - 1)/(3 - (-2)) =-4/5
Answer:
statement is false
Step-by-step explanation:
given data
men age = 4 year old
relation between = watching television and blood pressure
solution
we can say that this statement is wrong
because here causality it have never implied by correlation between these two watching television time period and the blood pressure as that by watching more time television that not causes high blood pressure
so that statement is false
