For me it is somethimes Because if th base 1 and base 2(which is always not congruent) can form a square, then if u draw a line with it then u can make right triangle with same sides which can use as a 45 45 90 or 30 60 90. Hope is helps

Consider the function f(x)=x3+4x2+2. find the points where the tangent line is horizontal.

lions [1.4K]

Thinking about the graph of f(x), the rate of change is zero whenever there is an extremum.

First, differentiate f(x)

$f'(x)=3x^2+8x$

Next, find the zeros of f'(x) by factoring.

$x(3x+8)=0 \\ x= \frac{-8}{3},x=0$

Now, we substitute these x-values into the original equation to find the coordinates.

(-2.667, 11.481), (0, 2)

A rectangle has an area of 20 ft.² in a similar rectangle has an area of 180 ft.² what is the ratio of areas of the similar

vovikov84 [41]

$\bf \qquad \qquad \textit{ratio relations}
\\\\
\begin{array}{cccllll}
&Sides&Area&Volume\\
&-----&-----&-----\\
\cfrac{\textit{similar shape}}{\textit{similar shape}}&\cfrac{s}{s}&\cfrac{s^2}{s^2}&\cfrac{s^3}{s^3}
\end{array}\\\\
-----------------------------\\\\$

$\bf \cfrac{\textit{similar shape}}{\textit{similar shape}}\qquad \cfrac{s^2}{s^2}=\cfrac{20}{180}\implies \left( \cfrac{s}{s} \right)^2=\cfrac{20}{180}\implies \cfrac{s}{s}=\sqrt{\cfrac{20}{180}}
\\\\\\
\cfrac{s}{s}=\cfrac{\sqrt{20}}{\sqrt{180}}\implies \cfrac{s}{s}=\cfrac{2\sqrt{5}}{6\sqrt{5}}\implies \cfrac{s}{s}=\cfrac{2}{6}\implies \cfrac{s}{s}=\cfrac{1}{3}$

John has 2456 pennies in his coin collection he has the same number of pennies in each of the three boxes estimate to the neares

Keith_Richards [23]

If I read correctly, 2456 pennies needs to be divided simply by 3 then rounded to the nearest hundredth. So you would do 2456/3 3 goes into 24 how many times? Then 3 goes into 5 how many times, then continue the pattern. Once you've gotten a decimal to the thousandth, round the number to the hundredth and there you go
