Answer:

46.5

Step-by-step explanation:

Of all straight angles have 180 degrees in them.

So, to find x we need to form this equation:

x + 65 + x - 22 = 180

2x + 43 = 180

2x = 180-43

2x = 137

68.5 degrees = x

68.5-22 = 46.5 degrees.

m<CBD = 46.5 degrees.

m<GBF = also 46.5 degrees because it is a vertical angle to <46.5 degrees.

“ write all your answers with a positive exponent so your answer will be in the form of x^# or 1/(x^#)

gayaneshka [121]

Answer:

Step-by-step explanation:

5). $\frac{1}{x^{-9}}$ = $\frac{1}{\frac{1}{x^9} }$

= $x^{9}$

6). $\frac{1}{x^{-2}}=\frac{1}{\frac{1}{x^2} }$

= x²

7). $x^{-6}=\frac{1}{x^6}$

8). $\frac{1}{x^{-7}}=\frac{1}{\frac{1}{x^7} }$

= $x^{7}$

9). $x^{-8}=\frac{1}{x^8}$

10). $\frac{1}{x^{-3}}$ = $\frac{1}{\frac{1}{x^{3}}}$

= x³

Find the general solution of y\"+9y=t^2*e^3t+6.

Fofino [41]

We are given with the equation y"+ 9 y = t^2 * e^3 t + 6 and asked to determine the general solution to this equation. we convert the equation into r^2 + 9 = 0. The solution to this equation is r = +/- 3i. This solution converted to trigonometric function is equivalent to y= C1 cos3t + C2 sin3t.
