In this question , we have to use sine law, which is

$\frac{sin \ Q}{PR} = \frac{sin \ P}{QR}$

$\frac{sin73}{68} = \frac{sin \ P }{47.6}$

$sin \ P = \frac{47.6 sin 73}{68}$

$P = sin^{-1} ( \frac{ 47.6 sin73}{68}) = 42$

Correct option is b.

Answer:

Step-by-step explanation:

Point estimate is always at the center of the interval.

You can find it by averaging the endpoints:

Which point do the graphs of f and g have in common?

pickupchik [31]

The point that the graphs of f and g have in common are (1,0)

<h3>How to get the points?</h3>

The given functions are:

f(x) = log₂x

and

g(x) = log₁₀x

We know that logarithm of 1 is always zero.

This means that irrespective of the base, the y-values of both functions will be equal to 0 at x=1

Therefore the point the graphs of f and g have in common is (1,0).

Given the differential Equation y'+2y=2e^x ;solve this equation using the integration factor; solve for y to get the general sol

SCORPION-xisa [38]

$y'+2y=2e^x\Longrightarrow y'=2e^x-2y$

If $f'(x)=g(x)$ then $y=\int{g(x)dx}$

So we extract,

$y=\int{2e^x-2x}dx$

Which becomes,

$y=2e^x-x^2+C$

Hope this helps.
