Step-by-step explanation: To shift the graphs up and down on the coordinate system, you need to manipulate or change the y-intercepts.
The y-intercept is just the constant term in the equation.
As long as the slopes remain the same, the graphs can be
translated up or down by changing the constant value.
Take a look at these lines graphed below.
Notice that y = x + 11 is the same as y = x + 4 but
y = x + 11 is translated 7 units down to get y = x + 4.
A. 7200 feet ÷ 3 minutes = x
Hope it helps!
And happy Pi Day! :D
<span>For computing this, follow this method:
4 loads of stone weigh 2/3 ton.
4loads---------------------2/3
1load---------------------?
So it will be computed as 1x 2/3 /4 = 2/3x4= 1/3x2=1/6
the weight of 1 load of stone is 1/6 ton
Hope this helps. Let me know if you need additional help!</span>
Answer:
21.5secs
Step-by-step explanation:
Given the function that models the height of an object as
h(t) = -16t^2+ 344t
The object hit the ground at h(t) = 0
Substitute
0 = -16t^2+ 344t
16t^2 = 344t
16t = 344
t = 344/16
t = 21.5
Hence it takes 21.5secs for the object to hit the ground
