June Tavia is trying to calculate the taxable equivalent yield for a municipal bond. If the bond she owns pays 4.5 percent inter
Zepler [3.9K]

Answer:

The taxable equivalent yield is 6%.

Step-by-step explanation:

The formula for the taxable equivalent yield is:

TEY = \frac{tax free bond }{(1-Tax rate)}\\ TEY = \frac{0.045 }{(1-0.25)}\\TEY = 0.06\\TEY = 6%

What are the solutions of 12 – x2 = 0? x = 2 StartRoot 3 EndRoot and x = Negative 2 StartRoot 3 EndRoot x = 3 StartRoot 2 EndRoo
krok68 [10]

Answer:

±2  sqrt(3) = x

Step-by-step explanation:

12 -x^2 =0

Add x^2 to each side

12 -x^2+x^2 =0+x^2

12 = x^2

Take the square root of each side

±sqrt(12) = sqrt(x^2)

We know that sqrt(ab) = sqrt(a) sqrt(b)

±sqrt(4*3) = sqrt(x^2)

±sqrt(4) * sqrt(3) = x

±2  sqrt(3) = x

Factor<br> x ^ 3 + 2x ^ 2 – 5x - 10 = 0
aleksklad [387]

Answer:

Step-by-step explanation:

When you have four terms and 3rd degree equation (the highest power is 3) you will want to try to "factor by grouping"

Group together two terms, watch out for the negative signs!

x^3 + 2x^2-5x-10=0

(x^3 + 2x^2) - (5x+10)=0

Find a common factor in each group and factor it out. You're hoping that what is left in the parenthesis is the same in both cases.

x^2(x+2)-5(x+2)=0

Now you can factor out that (x+2) because it is both terms.

x^2(x + 2) - 5(x + 2)=0

~~~~ ~~~~

Pull these out.

What will be left is the x^2 and the - 5 (dont lose that - in front of the 5)

(x + 2)(x^2 - 5) = 0

If all you have to do is factor, then you're done. It is factored. But if you have to "solve" also, then put x+2=0 and x^2-5=0 and solve.

x = -2 and x = +- sqrt5

HELP ME PLEASE! Part A: If (7^2)x = 1, what is the value of x? Explain your answer. (5 points)
ArbitrLikvidat [17]

Answer:

x=1/49, x=1

Step-by-step explanation:

part a:

so if (7^2)=49, you are left with 49x=1. we have to use inverse operations to isolate the variable x. this means we have to divide by 49 on both sides since 49 is multiplied with x. so, you are left with 1/49. x=1/49.

part b:

so according to the zero property, if you raise any number to the power of 0, you get 1. therefore, we are left with 1x=1. we can simplify this to x=1, which is the answer!

i think this is what you're asking for, if i misunderstood please comment under my response!
