I'd say the correct answer is D bc it's talking about the SAS theorem, excuse me if I'm wrong tho.
You plug in number for number getting 194.8 which is equal to 2931
Answer:
<h2>1. t=2m</h2>
Rewrite the equation as 2m=t.
2m=t
Divide each term by 2 and simplify.
m=t/2
<h2>2. y=2x+1</h2>
Isolate the variable by dividing each side by factors that don't contain the variable.
x=y/2−1/2
Step-by-step explanation:
Hope it is helpful....
I’m pretty sure it looks like it’s D
f'(x) = (4 arctan(7x))'
f'(x) = 4 (arctan(7x))'
By the chain rule,
f'(x) = 4/(1 + (7x)^2) * (7x)'
f'(x) = 28/(1 + 49x^2)
and hence
f'(4) = 28/(1 + 49*16) = 28/785
In case you're not sure about the derivative of arctan: If y = arctan(x), then x = tan(y). Differentiating both sides with respect to x gives
1 = sec^2y y' = (1 + tan^2y) y' = (1 + x^2) y'
==> y' = 1/(1 + x^2)
