The answer is A because it earns interest
Answer:
A'={a,c,e} by U={a,b,c,d,e,f,g}
A={b,d,f,g}
A' don't double A but answer union a,c,e
Answer:
x=2√3
Step-by-step explanation:
Let's solve your equation step-by-step.
x2
3
=4
Step 1: Simplify both sides of the equation.
1
3
x2=4
Step 2: Divide both sides by 1/3.
1
3
x2
1
3
=
4
1
3
x2=12
Step 3: Take square root.
x=±√12
x=2√3 or x=−2√3
So let's look at how to expand a binomial..
Start with just the variable exponents which will be numbered in ascending and descending order.
example (without coefficients)
(x+y)^3 = x^3(y^0) + x^2(y^1) + x^1(y^2) + x^0(y^3)
If the binomial is (x-y)^3 the +/- signs will toggle like so.. (again leaving out coefficients)
(x-y)^3 = x^3(y^0) - x^2(y^1) + x^1(y^2) - x^0(y^3)
If there is a coefficient or power inside the binomial like (x^2+2y)^3 these are also raised to the appropriate power.
(x^2+2y)^3 = (x^2)^3(y^0)(2^0) + (x^2)^2(y^1)(2^1) + ....
now there are also coefficients for each term which follow a combination pattern of Pascal triangle. C(3,0) ; C(3,1) ; C(3,2) ; C(3,3)
these get multiplied by each term.
So the 4th term of (x^2-2y)^3
will be negative
have coefficient of: C(3,3) * (2^3) = 8
variables: x^0(y^3) = y^3
= -8y^3
I believe it’s D bc 28.4 x 2 = 56.8 +151.6= 208.4 and supplementary angles need to be 180 or higher
