Answer:  The vertex form of the given function is y=2(x+2)^2-7.

Step-by-step explanation: We are given to express the following function in vertex form.

y=2x^2+8x+1~~~~~~~~~~~~~~~~~~~~(i)

We know that the vertex form of a quadratic function y=ax^2+bx+c is given by

y=a(x - h)2+k, where (h, k) is the vertex.

From equation (i), we have

y=2x^2+8x+1\\\\\Rightarrow y=2(x^2+4x+4)-8+1\\\\\Rightarrow y=2(x+2)^2-7.

Thus, the vertex form of the given function is y=2(x+2)^2-7.

What basic trigonometric identity would you use to verify that sinx cosx tanx=1-cos^2x
andre [41]

Answer:

sin^2x+cos^2x=1 is used to prove the given equation.

Step-by-step explanation:

We have given an equation:

sinx\cdot cosx\cdot tanx=1-cos^2x

We will consider right hand side first

tan x can be written as:

tanx=\frac{sinx}{cosx}

So, on substituting tan x in the left hand side of the given equation we get:

sinx\cdot cosx\cdot \frac{sinx}{cosx}

Cancel common term from denominator and numerator which is cosx we get

sin^2x

And we have an identity:

sin^2x+cos^2x=1

\Rightarrow sin^2x=1-cos^2x

Hence, right hand side is equal to sin^2x.

What is the slope of a line that is perpendicular to the line whose equation is 8y−5x=11?
ElenaW [278]

9514 1404 393

Answer:

  -8/5

Step-by-step explanation:

When you solve for y, the slope of the line is the x-coefficient. For the given line, that is ...

  8y = 5x +11 . . . . . add 5x

  y = 5/8x +11/8 . . . . divide by 8

The given line has a slope of 5/8. The perpendicular line will have a slope that is the opposite of the reciprocal of this:

  -1/(5/8) = -8/5 . . . . slope of perpendicular line
