Write the form of the partial fraction decomposition of the rational expression. Do not solve for the constants. 37 x2 − 6x

Dvinal [7]

Answer:

$\dfrac{A}{x}+\dfrac{B}{x-6}$

Step-by-step explanation:

Given the function $\dfrac{37}{x(x-6)}$ , to write the form of its partial fraction on decomposition, we will separate the two functions separated by an addition sign. The numerator of each function will be constants A and b and the denominator will be the individual factors of each function at the denominator. The partial fraction of the rational function is as shown below.

$= \dfrac{37}{x(x-6)}\\\\= \dfrac{A}{x}+\dfrac{B}{x-6}$

<em>Since we are not to solve for the constants, hence the partial fraction is </em> $\dfrac{A}{x}+\dfrac{B}{x-6}$

The distance between port M and port N is 162m. A ship left port M with a speed of 45 mph. In 45 minutes another ship left port

matrenka [14]

Answer:

After 900 minutes

Step-by-step explanation:

when we convert the velocities of the ships into miles/ min we get

$45mph=45m/60min=0.75m/min$

$36mph=36m/60min=0.6m/min$

The equations determining the distances of the ships from the port M (set at x=0) are

$D_1=0.75t$ (for 45mph ship)

$D_2=162+0.6(t-45)$ (for 36mph ship)

The solution to these equation lie at t= 900 minutes; therefore the two ships will meet 900 minutes after the departure of the first ship.

Drag each expression to match its equivalent expression. Each expression may be used only once.

ryzh [129]

Answer:

here it is in order

x^2 = 1 / x ^ -2

x^4 ÷ x^3 = x

(x^2)^2 = x^4

x^3 × x^3 × x^3 = x ^ 9
