(a) find the general solution to y^{\,\prime\prime} + 3 y^{\,\prime} = 0. give your answer as y = . . . \ . in your answer, use

KengaRu [80]

We want to solve
y'' + 3y' = 0

Solve the indicial equation.
m² + 3m = 0
m(m + 3) = 0
m = 0 or m = -3

The basic solutions are e⁰=1 and $e^{-3x}$ .

Answer:
The general solution is
$y(x) = c_{1} + c_{2}e^{-3x}$

Estimate the diameter of the supergiant star Betelgeuse, using its angular diameter of about 0.05 arcsecond and distance of abou

8090 [49]

0.05 arc-second = 1 degree/72000 = (pi radians)/(180*72000) = 2.424 x 10^(-7) radians

The distance is roughly:

R*(theta) = (600 light-years)*2.424 x 10^(-7) = 0.00014544 light-years = 1.275 light-hours = (3600 seconds)*(3 x 10^8 m/s)*(1.275) = 1.38 x 10^12 meters.

Need help asap this is really important

nadya68 [22]

Answer:

y = $\frac{4}{3}$ $x$ $-7$

Step-by-step explanation:

Use the points (9, 5) and (6, 1) to identify the slope of the graph

$m$ = $\frac{y^2-y^1}{x^2-x^1}$

m = $\frac{1-5}{6-9}$

m = $\frac{-4}{-3}$

m = $\frac{4}{3}$

The y-intercept is -7 because -7 touches y axis causing it to be the y-intercept

Quadrilaterals A and B are similar.

Alenkasestr [34]

Answer:

x = 17.5

y = 5

Step-by-step explanation:

Similar means that corresponding angles (same colors in this case) are the same. Rotate the 2nd figure on the right in your mind until the angle label colors fit the 1st figure, just so you can tell what's what. Then you can create ratios with corresponding sides that include only one of the unknowns. So 1st we use

x/7 = 15/6

x = 15/6 * 7

x = 17.5

and

y/12.5 = 6/15

y = 6/15 * 12.5

y = 5
