mel-nik [20]

Answer:

A. $-2\sqrt{2\pi }$

Step-by-step explanation:

$f(x)=sin(x^{2}+\pi )$

$f^{'}(x)=cos(x^{2} +\pi ) 2x$

$f^{'}(\sqrt{2\pi } )=cos(2\pi +\pi )2\sqrt{2\pi }$

$f^{'} (\sqrt{2\pi } )=-1 (2\sqrt{2\pi } )$

Find the area of the triangle

anzhelika [568]

Answer: 305.9m
Area of a Triangle is 1/2 base X height
So (b)(h) = 2.1m X 19m=39.9m (210 cm = 2.1 m)
Now that we have the base which is 39.9m
We do the sides which is 1/2*28*19=266m
Now that we have the sides, we add the base which is 39.9m and the Height which is 266m, then we get our answer: 305.9m

I hope this helped you. Goodluck, and please give me a Branliest if available. Thanks. :)
