Amplitude:

we can see that

maximum value is 3

minimum value is -1

so,

$A=\frac{max-min}{2}$

$A=\frac{3+1}{2}$

$A=2$

Period:

It is time completed after which value repeats itself

so, we get

$T=\pi -0$

$T=\pi$

so,

option-D............Answer

Are the following polygons similar explain

ra1l [238]

<h3>Answer: No, they are not similar.</h3>

Technically, we don't have enough info so it could go either way.

==========================================================

Explanation:

We can see that the sides are proportional to each other, but we don't know anything about the angles. We need to know if the angles are the same. If they are, then the hexagons are similar. If the angles are different, then the figures are not similar.

Right now we simply don't have enough info. So they could be similar, or they may not be. The best answer (in my opinion) is "not enough info". However, your teacher likely wants you to pick one side or the other. We can't pick "similar" so it's best to go with "not similar" until more info comes along the way.

Find f if f′(x)=2x−3/x^4, x>0 and f(1)=2.

slavikrds [6]

$f'(x)=2x-\dfrac3{x^4}$
$\displaystyle\int f'(x)\,\mathrm dx=\int\left(2x-\frac3{x^4}\right)\,\mathrm dx$
$f(x)=x^2+\dfrac1{x^3}+C$

Given that $f(1)=2$ , we get

$2=1^2+\dfrac1{1^3}+C$
$2=2+C$
$\implies C=2$

so that

$f(x)=x^2+\dfrac1{x^3}$

79=11x+13 <br> Solve each equation by using the properties of equality and justify each step

neonofarm [45]

Solution: X=6

Detailed explanation:

In this problem we're asked to find "x" or the unknown.

The first step is to subtract 11x from both sides.

$---\mapsto\boldsymbol{-11x+79=13}$

Next, subtract 79 from both sides.

$---\mapsto\boldsymbol{-11x=-66}$

To finish this off, divide both sides by -11.

$---\mapsto\boldsymbol{x=6}$

Voila! There's our answer!

one leg of a right triangle has length 7. the lengths of the other two sides are whole numbers. the length of the other leg is ?

zalisa [80]

Sets of three integers that could be right triangles are called pythagorean triples. the only pythagorean triple including 7 is 7, 24, and 25. so the length of the other leg is 24 and the length of the hypotenuse is 25. hope this helped!
