The base of the triangle is 60 m, height - 12 cm, the median of the base - 13 cm. Find the sides.
Mashutka [201]

Answer:

Let ABC be the given isosceles triangle in which AB=AC=13cm. Draw AD perpendicular from A on BC

Let BC=2x cm. Then BD=DC=x cm

In △ABD, we have

AB

+AD

+BD

(By pythagoras theorem)

⇒13

2

=AD

⇒AD=

=

169−x

Now, Area =60cm

)=3600

⇒(x

⇒x=12orx=5

Hence, Base 2x=24cm or 10cm

c2*sin(wt)+c1*cos(wt)= A*Sin(wt+phi), where c2=Acos(Phi) and c1=Asin(Phi). They ask me to find the amplitude of the function 2 s
Iteru [2.4K]

The amplitude of A\sin(\omega t+\phi) is the absolute value of A. So first you need to condense the given function into one sine expression.

Recall that

A\sin(\omega t+\phi)=A\sin(\omega t)\cos\phi+A\cos(\omega t)\sin\phi

so you need to choose \phi and \omega accordingly.

If we line up the terms of the given function with the expanded one above, we should have

2\sin(4\pi t)+5\cos(4\pi t)\implies\begin{cases}A\cos\phi=2\\A\sin\phi=5\\\omega=4\pi\end{cases}

Now, using the Pythagorean identity,

(A\sin\phi)^2+(A\cos\phi)^2=2^2+5^2\implies A^2=29\implies A=\pm\sqrt{29}

so the amplitude is √29.

Just for completeness, we also get

\tan\phi=\dfrac{\sin\phi}{\cos\phi}=\dfrac52\implies\phi=\tan^{-1}\left(\dfrac52\right)+n\pi

where n is any integer.

What does the line 5x+2y=8 look like?
tekilochka [14]
5x + 2y = 8
2y = -5x + 8
y = -5/2x + 4....slope here is -5/2, and since the slope is negative, ur line is going down....slant right downwards.
