If y= -cos x, what x-value corresponds to a y-value of 1 between 0 and 2 pi

The x-value corresponds to a y-value of 1 is π

Step-by-step explanation:

The given is:

  • y = - cos x
  • y = 1
  • 0 < x < 2π

We need to find x when y is 1

∵ y = - cos x

∵ y = 1

∴ 1 = - cos x

- Multiply both sides by -1

∴ -1 = cos x

- Switch the two sides

∴ cos x = -1

- Use the inverse of cos to find x

∴ x = cos^{-1}(-1)

∵ cos(π) = -1

∴ x = π

The x-value corresponds to a y-value of 1 is π

Look to the attached graph for more understand

<em>The graph of y = 1 intersects the graph of y = - cos x at x = π from 0 to 2π</em>

(a) One possibility is 8.45

Rounded to the nearest integer = 8

Rounded to the nearest tenth = 8.5

And rounding this to the nearest integer = 9

 

(b) The possible numbers are 8.45 to 8.49, inclusively

Solve the equation without the use of a calculator. please Help!!! Thank you!!!<br> 12x^3-30x=5-2x^2
nata0808 [166]

So, since we have a cubic equation with 4 terms, the first thing we should try is factoring by grouping, so:

12x^3+2x^2-30x+5 =0 \implies \\ 2x^2(6x+1)-5(6x+1)=0 \implies \\ (2x^2-5)(6x+1) = 0

Now that we've factored our equation, we can use ZPP and break it up:

2x^2-5 = 0 \implies \\ 2x^2=5 \implies\\ x^2=\frac{5}{2} \implies\\ x=\pm\frac{\sqrt{5}}{\sqrt{2}}=\pm\frac{\sqrt{10}}{2} \\ \\ 6x+1 =0 \implies \\ 6x=-1 \implies\\ x=\frac{-1}{6}

So, our solutions are:

x\in \{\frac{\sqrt{10}}{2},-\frac{\sqrt{10}}{2},-\frac{1}{6}\}
