Answer:

quadrant II

Step-by-step explanation:

quadrant III is located bottom left/ (-x, -y). Rotated 90° clockwise it would go to the right just like a clock which would end up in quadrant II which is too left quadrant (-x, y)

Use linear approximation to approximate √25.3 as follows.

Sophie [7]

The idea is to use the tangent line to $f(x)=\sqrt x$ at $x=25$ in order to approximate $f(25.3)=\sqrt{25.3}$ .

We have

$f(x)=\sqrt x\implies f(25)=\sqrt{25}=5$

$f'(x)=\dfrac1{2\sqrt x}\implies f'(25)=\dfrac1{10}$

so the linear approximation to $f(x)$ is

$L(x)=f(5)+f'(5)(x-5)=5+\dfrac{x-5}{10}=\dfrac x{10}+\dfrac92$

Hence $m=\frac1{10}$ and $b=\frac92$ .

Then

$f(25.3)\approx L(25.3)=\dfrac{25.3}{10}+\dfrac92=\boxed{7.03}$

what is the probability that a randomly chosen number is less than or equal to 90 and is a multiple of 17

kodGreya [7K]

Answer:

let's see...

we have total possible outcomes.. = 90 ( from 1 to 90)

Desiree outcomes..= 5 ( 17,34,51,68,85)

and therefore.. the probability is 5/90 = 1/18.

here you go.. that should be correct I hope.

Find the distance between each pair points (-5,3) , (-4,-5)?

tester [92]

The distance formula is d=√(x2-x1)² + (y2-y1)²

So... d =8.06226

Hope this helps

3) g(n) = 2n<br> h(n) = n² + 5<br> Find (g + h)(n)

elena55 [62]

(g + h)(n) =
g(n) + h(n) =
2n + n^2 + 5 =
n^2 + 2n + 5 (standard form)
