Help math question derivative!

atroni [7]

Let $f(x)=\sec^{-1}x$ . Then $\sec f(x)=x$ , and differentiating both sides with respect to $x$ gives

$(\sec f(x))'=\sec f(x)\tan f(x)\,f'(x)=1$
$f'(x)=\dfrac1{\sec f(x)\tan f(x)}$

Now, when $x=\sqrt2$ , you get

$(\sec^{-1})'(\sqrt2)=f'(\sqrt2)=\dfrac1{\sec\left(\sec^{-1}\sqrt2\right)\tan\left(\sec^{-1}\sqrt2\right)}$

You have $\sec^{-1}\sqrt2=\dfrac\pi4$ , so $\sec\left(\sec^{-1}\sqrt2\right)=\sqrt2$ and $\tan\left(\sec^{-1}\sqrt2\right)=1$ . So $(\sec^{-1})'(\sqrt2)=\dfrac1{\sqrt2\times1}=\dfrac1{\sqrt2}$

Answer:

< - 5, 3.5 >

Step-by-step explanation:

A single translation is required to map A onto B

Consider the point (5, 3 ) on A and the corresponding point (0, 6.5) on B

the translation is < 0 - 5, 6.5 - 3 > = < - 5, 3.5 >

-17y = 29

2. 8 = 1/60 + a. 8 - 1/60 = 7.98333333333

6 = 1/80 + b. 6 - 1/80 = 5.9875

Will give brainliest please help ASAP

Answer: 1) If we talk about whole numbers then we should choose only square numbers that could be the area of square so that if we want to find its side so we a can find its square root i.e. side.

2) We can find the square root of the area of the given square to find the side length of the square.

3) No , it is not possible to find a side length that would be perfect for a square with an area of 45 square units because if we find its side we need to find its square root i.e.

$side=\sqrt{45}=\sqrt{3\times3\times5}=3 \sqrt{5}$ ................>which is irrational and √5=2.236

∴side=3×2.236=6.708 unit ......> which is not accurate we need to take approx value of it to get the side length of the square.
