The equation for this is ; y=1/2(x+4)^2-1

Explain

we use the vertex form
y=a(x-h)^2+k where the vertex is (h,k)

Select ( -4,-1)


Where h=-4
K=-1


y=a(x-h)^2+k

We get

y=a(x-(-4))^2+ -1

Y= a(x+4)^2+-1

Now replace to 0,7

7=a(0+4)^2-1

7=a(4)^2-1

7=16a-1


So now

7=16a-1
7+1=16a

8=16a
a=8/16
That should 1/2

So y=a(x+4)^2 -1
Should become

Y=1/2(x+4)^2 -1



Do you have any doubts now !

What are the amplitude, period, and phase shift of the given function? f(t)=-2/3 cos (3t-3pi)
dybincka [34]

Answer:

amplitude; \frac{2}{3}

Phase shift; \pi units right

Period;\frac{2\pi}{3}

Step-by-step explanation:

The given function is

y=-\frac{2}{3}\cos(3t-3\pi)

This function is of the form;

y=A\sin (Bt+C)

The period is given by:

|A|=|-\frac{2}{3}|= \frac{2}{3}

The period is given by:

T=\frac{2\pi}{|B|}= \frac{2\pi}{|3|}=\frac{2\pi}{3}

The phase shift is given by;

\frac{C}{B}=\frac{-\3pi}{3}=- \pi or \pi units right.

Please answer ASAP will mark brainliest if correct
Mekhanik [1.2K]

Answer:

3, 5, 7

Step-by-step explanation:

As per triangle inequality theorem:

  • <em>Any side of a triangle must be shorter than the other two sides added together</em>

Assume the sides are equal to 3 smallest odd numbers: 1,3 and 5

  • Then 1+3< 5 and it is against the above rule, so this is not correct

The next triple is: 3, 5 and 7

  • Then 3+ 5 > 7 and it is correct

So 3, 5, 7 is the combination of smallest odd numbers to make sides of a triangle
