Solve for p. i = prt p = i-rt p = (rt)/i p = i/(rt)

andrezito [222]

Answer:

$\sf p = \dfrac{i}{rt}$

Step-by-step explanation:

Solve for p:

$\longrightarrow$ i = prt

i = prt is equivalent to prt = i:

$\longrightarrow$ prt = i

Divide both sides by rt:

$\longrightarrow$ $\sf \dfrac{prt}{rt} = \dfrac{i}{rt}$

$\sf \dfrac{prt}{rt} = p:$

$\longrightarrow$ $\sf p = \dfrac{i}{rt}$

Simplify x^3 y^3 / x^3 y^3

Marysya12 [62]

Answer:

$\frac{1}{y}$

Step-by-step explanation:

When simplifying an exponent a way to do is to expand the exponent. This means that it will now be

$\frac{x*x*x*y*y*y}{x*x*x*y*y}$

Whenever you see an x or y on the numerator and denominator cross it out because it is the same thing as 1

When you cross out all of the x's and y's the only variable left is y in the denominator. This means that the answer is $\frac{1}{y}$

Of the five quadratics listed below, four of them have two distinct roots. The fifth quadratic has a repeated root. Find the val

musickatia [10]

Answer: 3/5

Step-by-step explanation: The fourth quadratic in the list is the square of a binomial:

25x^2 - 30x + 9 = (5x - 3)^2

Therefore, the repeated root of this quadratic is the solution to 5x - 3=0, which is 3/5
