Aparticle moves along the curve y=7 x 2+4y=7 x 2+4 in such a way that its xx-coordinate is changing at a rate of −5−5 centimeters per second. at what rate is the particle's yy-coordinate changing when the particle is at the point where x=1x=1?

The y-coordinate is changing by the rate of -70 cm per sec.

Step-by-step explanation:

Given equation,

Differentiating with respect to time (t),

We have,

range =5

step-by-step explanation:

to find the range, we take the largest value and subtract the smallest value.

the largest value is 5

the smallest value is 0

the range is 5-0   =5
