<span>From the pythagorean theorem, we know that x^2 and y^2 = 15^2, where x and y, where x is the base moving from the wall and y is the distance of the ladder sliding down. This means that y = sqrt(225 - x^2). Plugging in x = 13 gives us y = 2sqrt(14). Differentiating both sides of the original equations gives us dy/dt = 13 x 4 / 2sqrt(14) = 52/2sqrt(14) = 26/sqrt(14) ft/s.</span>
Step-by-step explanation:
area of a circle = 19.7cm²
πr²= 19.7cm²
22/7 r²= 19.7
r= 2.50 cm
We call m the slope<span> or gradient of the </span>line<span>. It </span>represents<span> the change in y-value </span>per<span> unit change in x-value. For example, consider the </span>line<span> given by the equation y = 2x + 1. Here are some points on the </span>line<span>. ~hope that helps</span>
It needs to be 1,2,3,4,5,6,15,39,35
