Answer:
Step-by-step explanation:
^3√x is improperly formed. I'd guess you meant "the third root of x," which looks like ∛x. Note that Brainly's workspace has built-in math symbols. Try them out by clicking on the Greek letter omega (below).
The domain of f(x) = ∛x is "all real numbers."
We are given some statements, we need to find which of the given statements is an advantage to using equations.
<h3><em>The correct option is </em></h3><h3><em>(A). When given two names for the same quantity, you can use algebra to solve the equations.</em></h3>
Incorrect options are :
(B). You can forget what an equation represents when it is used by itself.
(C). every problem needs an equations if you want to solve it.
Answer:
(A)
(B)
Step-by-step explanation:
We have to find the Laplace transform
(a) x(t) + 7 x(t) = 5 cos2t
Taking Laplace of both side
(B)
Taking Laplace transform of both side
<span><span>A certain drug is made from only two ingredients: compound A and compound B. There are 5 milliliters of compound A used for every 4 milliliters of compound B. If a chemist uses 255 milliliters of compound A, how many milliliters of the drug will be made?
----------------------------------
4:5 is the same as 4x:5x where 4x is compound A and 5x is compound B.
---
Solve for "x":
If amount of compound A is 4x = 255
