Answer: means you can switch up the numbers

Step-by-step explanation:

so Commutative Property means you can switch up

the numbers not the sign for example.

4 × 3 × x

4 × x × 3

3 × x × 4

x × 3 × 4

x × 4 × 3

if you look at all these! they just switch

this is easier like 4x5=20 in communicative property it would be 5x4=20

Hope this helps :)

Determine the value of a if one solution to the quadratic equation is x equals 5 + 3/2 I

Sindrei [870]

The value of a is $\frac{-9}{4}$

Step-by-step explanation:

1. Determine the other solution of x

If one value is 5 + $\frac{3}{2}$ then the other value is 5 - $\frac{3}{2}$

2. Use reverse technique to find the equation

(5 + $\frac{3}{2}$ ) (5 - $\frac{3}{2}$ ) = 0

25 - $\frac{-15}{2}$ + $\frac{15}{2}$ - $\frac{9x^{2} }{4}$ = 0

- $\frac{9x^{2} }{4}$ + 25 = 0

3. The equation is - $\frac{9x^{2} }{4}$ + 25 = 0

4. Find the value of a

a is the number with the variable $x^{2}$ therefore it is - $\frac{9}{4}$

The function f (x) = cube root of x is an example of a logarithmic function. true false

xxMikexx [17]

This is a false statement.

The cube root of x also means x raised to the 1/3rd power. In order for it to be a logarithmic function, it needs to grow as a inverse to a power function. Since we still have a number raised to a power (albeit a very low power) it is not a logarithmic function.

All logarithmic functions will approach the y axis as they get lower and lower. The cube root of x will actually hit the y-axis at (0, 0)

This is a binomial distribution.
p = 0.71, q = 1 - p = 1 - 0.71 = 0.29, n = 20

P(x ≤ 19) =1 - P(x = 20) = 1- 20C20 x (0.71)^(20 - 20) x (0.29)^20 = 1 - 0.29^20 = 1 - 0 = 1

Answer:

C.)$31,390

Step-by-step explanation:

You can use the formula to calculate the future value to find the answer:

FV=PV*(1+i)^n

FV= future value

PV= present value= 29,000

i= interest rate=2%

n= number of periods of time= 4

Now, you can replace the values in the formula:

FV=29,000*(1+0.02)^4

FV=29,000*(1.02)^4

FV=31,390

According to this, the answer is that the annual rent would be $31,390 at the end of four years.
