How long will it take an object dropped from a window to fall a distance of 78.4 meters?
Free_Kalibri [48]
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

Consider the function f(x) = mx + b, where m > 0.
Mrac [35]

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.
