Find the angle to the nearest degree. * sin-10.5166 1 31.1° 58.9° 0.5°

Mice21 [21]

Given:

The given inverse trigonometric term is:

$\sin^{-1}(0.5166)$

To find:

The value given inverse trigonometric term.

Solution:

We have,

$\sin^{-1}(0.5166)$

Using the calculator, we get

$\sin^{-1}(0.5166)=31.10446$

$\sin^{-1}(0.5166)\approx 31.1^{\circ}$

The value of given term is 31.1°.

Therefore, the correct option is B.

When using rational expectations, forecast errors will, on average, be ________ and ________ be predicted ahead of time. A) zero

mafiozo [28]

Answer:

A) zero; cannot

Step-by-step explanation:

In line with the principle of rational expectations, expectation errors are unpredictable. The expectations of all available information will not differ from the optimal projections.The word optimal projection is inexorably intertwined with the best guess in rational expectations theory.

If anyone could help?

Trava [24]

Answer:

$y=\frac{5}{7}x$ and $y=\frac{7}{9}x$

Step-by-step explanation:

A simple way to solve this problem is to plug the corresponding x and y into the function. We need only one pair since all the functions are quasi-linear (y=kx) and the increase is proportional.

In $y=\frac{5}{7}x$ when x=3, y=15/4≈2.14

In $y=\frac{3}{5}x$ when x=3, y=1.8
