Answer:
The constant of proportionality in this case would be 4
Step-by-step explanation:
To find the constant of proportionality, you need to solve for y. Then use the coefficient of x as k, which is the constant of proportionality.
6y = 24x
y = 4x
Answer:
10.8 cm
Step-by-step explanation:
we know that
1) A square picture with side length 30 cm is scaled by 60% on a photocopier
Remember that

so
The length of the first copy of the picture is

2) The copy is then scaled by 60% again
so
The length of the second copy of the picture is

Answer: Option D is correct .
Step-by-step explanation:
Since we have given that


In option D,

Otherwise ,
In all other options , there is no other function whose value comes out to be 24x.
Like , in option b,

which is not equivalent to

Hence, option D is correct.
Its 50, its in the 10s place
So you have to find the velocity (or first derivative) from the position function of h=-16t^2+48t+6
the velocity is -32t+48 which you then have to set equal to 0 in order to find t
-32t+48=0
-32t=-48
t=1.5
you then take your t value and sub it back into your original position function
-16(1.5)^2+48(1.5)+6 which will give you a maximum height of 42 feet
so the time it takes is 1.5 seconds to reach a maximum height of 42 feet
