A high-altitude spherical weather balloon expands as it rises, due to the drop in atmospheric pressure. Suppose that the radius
lord [1]
The increase of the radius is a linear increase since we have the constant rate of 0.07 inches per second

The equation for a linear growth/decay is given by the form y=mx+c where m is the rate of increase and c is the value of y when x=0

We have 
m = 0.07 
c=36 when t=0

So the equation is r=0.07t+36

The length of the radius when t=400 seconds is
r=0.07(400)+36
r=64 inches

HELP QUICK! On a coordinate plane, the coordinates of vertices R and T for a polygon are R(−6, 2) and T(1, 2). What is the lengt
Savatey [412]
They are both on the 2 of the y-axis, so now all you have to do is subrtact the x-axis coordinate of R by the x-axis coordinate of T. That would be (-6)-5 = -11. YOUR ANSWER IS NOT -11. Signs don't matter when your attempting to find distance. Just forget the negative sign(-). It has nothing to do with the answer.
YOUR ANSWER IS 11 UNITS!!!

Let's solve for x ~

\qquad \sf  \dashrightarrow \:4x - 16 = 64

\qquad \sf  \dashrightarrow \:4(x - 4) = 64

\qquad \sf  \dashrightarrow \:(x - 4) = 64 \div 4

\qquad \sf  \dashrightarrow \:x - 4 = 16

\qquad \sf  \dashrightarrow \:x  = 16 + 4

\qquad \sf  \dashrightarrow \:x  =20
