Answer: 2/15
Step-by-step explanation:
25-21/30 = 4/30
4/30 = 2/15
<span>y = tan^−1(x2/4)</span>
tan(y) = x2/4
sec2(y) = x/2
y′ = xcos^2(y)/2
<span>cos^2(y) = <span>16x2+16</span></span>
<span>y′ = <span>8x/(<span>x2+16)
let u be x2+16
du is 2x dx
dy = 4 du / u
y = 4 ln (</span></span></span>x2 <span>+ 16)
y at x =0 = </span> 4 ln (<span>16) = 11.09</span>
Answer:
Step-by-step explanation:
Let's get all of the terms with the 
on the right-hand side of the equation, and everything else on the left-hand side of the equation.
To do this, we should add 
to both sides of the equation to remove the 
from the left-hand side of the equation:
Finally, to get the by itself, we can divide both sides by 
:
Answer:
0.375 feet.
Step-by-step explanation:
Multiply .25 by 1.5 to get 0.375.
