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>

Evaluate the series 4 – 2 + 1 – 0.5 + 0.25 to S10. Round to the nearest hundredth.
aleksklad [387]
The initial term of this geometric series is 4, and the common ratio is -1/2. The sum is given by

S_{n}=a_{1}\dfrac{r^{n}-1}{r-1}\\\\S_{10}=4\cdot \dfrac{(-\frac{1}{2})^{10}-1}{-\frac{1}{2}-1}=4\cdot \dfrac{(\frac{1}{1024}-1)}{(-\frac{3}{2})}\\\\=\dfrac{8}{3}\cdot \dfrac{1023}{1024}=\dfrac{341}{128}

The sum is approximately 2.66.

the angles of a triangle are in the ratio 3:4:5. what is the degree measure of the smallest angle of the triangle?
Alik [6]
A triangle interior angles add up to 180

so we have 3:4:5
the ratio of the angles
 3+4+5=12
therefor 180=12 units
divide by 12
15=1 unit
subsitute
find the smallest unit
