Find two consecutive even integers such that twice the second is the same as 186 less than the first integer.​

Mathematics
1 answer:
Alisiya [41]3 years ago
6 0

Step-by-step explanation:

let the 2 integers be x and x + 1

2(x + 1) + 186 = x

2x + 188 = x

x = -188

therefore the 2 integers are -188 and -187

Find vertex of: <br><br> y=(x-4)(x+8)
ki77a [65]

Answer:

(-2,-36)

Step-by-step explanation:

y=(x-4)(x+8)

<u>1) Find the zeros of the parabola</u>

The zero-product property states that any value, when multiplied by 0 will equal 0. Therefore, to make y=0, either (x-4)=0 OR (x+8)=0.

Therefore, x=4 and x=-8.

<u>2) Find the x-coordinate of the vertex</u>

To do this, we take the average of our zeros.

\frac{4+(-8)}{2} \\=\frac{-4}{2} \\=-2

Therefore, the x-coordinate of the vertex is -2.

<u>3) Find the y-coordinate of the vertex</u>

Plug the x-coordinate back into the original equation

y=(-2-4)(-2+8)\\y=(-6)(6)\\y=-36

Therefore, the y-coordinate of the vertex is -36.

Therefore, the vertex of the parabola is (-2,-36).

I hope this helps!

If angle 0 is in quadrant I, what is the value of
Brilliant_brown [7]

Answer:

the \: answer \: is \: c \:  =  -  \frac{ \sqrt{14} }{5}

Step-by-step explanation:

\sin^{2}0 + ( \frac{ \sqrt{11} }{5} ) ^{2}  = 1( \sin^{2}0 +  \cos^{2} 0 = 1)

{ \sin }^{2}0 +  \frac{11}{25} = 1   \\  { \sin }^{2}0 =  \frac{14}{25}

\sin0_{1} =  -  \frac{ \sqrt{14}}{5} while \sin0_{2} =  \frac{ \sqrt{14} }{5}

  • Therfore theta is QI
  • Therfore sin theta >0
  • therefore \:  \sin0 =  \frac{ \sqrt{14} }{5}
