How do I find the value of the variable?

wariber [46]

the three inside angels need to equal 180, so first find the missing inside angle:

86.5 + 41.4 = 127.9

180-127.9 = 52.1

now that angle and y need to equal 180 degrees

so 180 - 52.1 = 127.9

y = 127.9 degrees

Solve the Method of variation of Parameters. y" - 3y' + 2y = 4e^3t

kirill [66]

Answer:

CF+PI= $c_1e^{2x}+c_2e^{x}$ + $2e^{3t}$

Step-by-step explanation:

we have given y"-3y'=2y= $4e^{3t}$

this differential equation solution have two part that CF and PI

CALCULATION OF CF :

$m^2-3m+2=0$

$m^2-2m-m+2=0$

$(m-1)(m-2)=0$

m=1 and m=2

so CF= $c_1e^{2x}+c_2e^{x}$

CALCULATION OF PI :

PI = $\frac{4e^{3t}}{(m-1)(m-2)}$

at m= 3 in PI

$PI=\frac{4e^{3t}}{2}=2e^{3t}$

so the complete solution is

CF+PI= $c_1e^{2x}+c_2e^{x}$ + $2e^{3t}$

If f(x) = 3^2 + 10x and g(x) = 2x-4, find (f-g)(x).

Marat540 [252]

What we know:

$f(x)=3^2+10x\\g(x)=2x-4$

(Also, $3^2=9$ )

What we need to solve:

$(f-g)(x)$ (This is equal to $f(x)-g(x)$ )

How you have to subtract $f(x)$ with $g(x)$ to get:

$(f-g)(x) = f(x)-g(x) = 9+10x+2x-4 = 12x+5$

Thus, the answer would be:

$12x+5$
