Calculate the average rate of change over the intervals [0, 20] and [60, 80]. What does the average rate on these intervals tell

Assoli18 [71]

$\frac{20 - 80}{0 - 60 } = slope \: or the \: rate \: of \: \\ change \: \\ \\ \frac{ - 60}{ - 60} = 1$
It tells you that over these intervals the balloon is going at a constant speed.

Math- Differentiation . Could you help me to solve this question?

Arlecino [84]

Answer:

Step-by-step explanation:

Hello, first of all we can find a value for f(1)

$xf(x)+f(x^2)=2 \\\\\text{So for x = 1, it gives}\\\\f(1)+f(1^2)=f(1)+f(1)=2f(1)=2\\\\ f(1) =1$

And we can get the derivative of the equation so.

$(uv)'=u'v+uv' \text{ and } \dfrac{df(x^2)}{dx}=2xf'(x^2) \text{ so we can write}\\\\f(x)+xf'(x)+2xf'(x^2)=0\\\\\text{And then, for x = 1}\\\\f(1)+f'(1)+2f'(1)=0\\\\ f(1)+3f'(1)=0\\\\ 3f'(1)=-f(1)=-1\\\\\large \boxed{ f'(1)=-\dfrac{1}{3} }$

Thank you

50 POINTS EACH HEEEEELP !!!!!

Phoenix [80]

Hello there,

The <em>answer is </em>A' (-3,2).

<h3>Step-by-step explanation:-</h3>

From the image shown on the xy-plane, the coordinate of point A is at (3,-2).

The rule for rotation by 180° about the origin is (x,y)→(-x, -y), where (x,y) is the coordinate of image and (-x, -y) is the coordinate of the resulting pre-image.

Given the coordinate point A(3,-2), if this coordinate is rotated 180°, the resulting point A' will be located at (-3,-(-2)) = (-3,2).

Therefore, the answer will be <u>A'(-3,2)</u>
