Divide m2n2/p3 by mp/n2 .
Answer:
The answer is 'm'.
Step-by-step explanation:
Here, the given expression,
[tex]\frac{\frac{m^2n^2}{p^3}}{\frac{mp}{n^2}}[/tex]
[tex]=\frac{m^2n^2\times n^2}{p^3\times mp}[/tex]
[tex]=\frac{m^2n^{2+2}}{p^{3+1}m}[/tex] ( [tex]a^m.a^n=a^{m+n}[/tex] )
[tex]=\frac{m^2p^4}{p^4m}[/tex]
[tex]=m^2p^4p^{-4}m^{-1}[/tex] ( [tex]a^{m}=\frac{1}{a^{-m}}[/tex] )
[tex]=m^{2-1}p^{4-4}[/tex]
[tex]=m^1p^0[/tex]

Payout Annuities:
1. You want to be able to withdraw $30,000 from your account each year for 15 years after you retire.
You expect to retire in 30 years.
If your account earns 5% interest, how much will you need to deposit each year until retirement to achieve your retirement goals?
To achieve your retirement goals of withdrawing $30,000 per year for 15 years, you will need to deposit approximately $121,200 each year until retirement.
Explanation:To determine how much you need to deposit each year until retirement, you can use the formula for the present value of an annuity. The formula is:
PV = PMT x ((1 - (1 + r)^-n) / r)
Where:
In this case, the annuity payment amount is $30,000, the interest rate is 5%, and the number of periods is 15 years. Plugging these values into the formula:
PV = $30,000 x ((1 - (1 + 0.05)^-15) / 0.05)
Simplifying the equation:
PV = $30,000 x ((1 - 1.798) / 0.05)
PV = $30,000 x (0.202 / 0.05)
PV = $30,000 x 4.04
PV = $121,200
Therefore, you will need to deposit approximately $121,200 each year until retirement to achieve your retirement goals.

In how many ways can 3 boys and 3 girls sit in a row if the boys and girls are each to sit together?
The boys and girls are each to sit together, and there are 3 boys and 3 girls. The total number of ways to arrange them is 36.
Explanation:The boys and girls are each to sit together, meaning that the boys should sit together in one group and the girls should sit together in another group. We can consider these two groups as two separate entities.
The number of ways to arrange the boys within their group is 3! (3 factorial), because there are 3 boys. Similarly, the number of ways to arrange the girls within their group is also 3!. Since these two groups can be arranged independently of each other, the total number of ways to arrange the boys and girls is 3! * 3! = 6 * 6 = 36.
Is m=0.75d-2 proportional?
Answer:
No, the equation m=0.75d-2 does not represent proportional relationship.
Step-by-step explanation:
The given equation is
[tex]m=0.75d-2[/tex]
We need to check whether the given equation represents proportional relationship or not.
If variable y is proportional to variable x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
where, k is the constant of proportionality.
At x=0 the value of y is 0. It means, if a linear equation represents proportional relationship then it must be passes though the origin.
Substitute d=0 in the given equation.
[tex]m=0.75(0)-2[/tex]
[tex]m=-2[/tex]
The line passes through the point (0,-2).
Since the line does not pass through the origin, therefore it does not represent proportional relationship.

f (x) = x5 − 8x4 + 21x3 − 12x2 − 22x + 20 Three roots of this polynomial function are −1, 1, and 3 + i. Which of the following describes the number and nature of all the roots of this function?
f (x) has two real roots and one imaginary root.
f (x) has three real roots.
f (x) has five real roots.
f (x) has three real roots and two imaginary roots.
Answer:
It's D on edge.
The f(x) has three real roots and two imaginary roots option (D) is correct.
What is polynomial?Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

We have a polynomial:
f(x) = x⁵ − 8x⁴ + 21x³ − 12x² − 22x + 20
The three roots of this polynomial function are −1, 1, and 3 + i.
We can write the function in a factored form:
f(x) = (x - 1)(x⁴ - 7x³ + 14x² +2x - 20)
Again factoring the above polynomial:
f(x) = (x - 1)(x + 1)(x - 2)(x² -6x + 10)
The roots of the polynomial are
x - 1 = 0
x = 1
x + 1 = 0
x = -1
x - 2 = 0
x = 2
x² - 6x + 10 = 0
The above quadratic equation has two complex roots.
x = 3 + i
x = 3 - i
Thus, the f(x) has three real roots and two imaginary roots option (D) is correct.

A. y=5/7x
B. y=3/5x
C. y=1/3x
D. y=7/9x
E. y= 7/11x
(a) y=5/7x and (d) y=7/9x have a greater unit rate than the rate represented in the table.
What is slope intercept form?y=mx+c is the slope intercept form where m is the slope and c is y intercept.
The given table is
x 3 6 9
y 2 4 6
The formula to calculate slope is m =y₂-y₁/x₂-x₁
(3,2 ) and (6, 4) are two points.
x₁=3, y₁=2 , x₂=6 and y₂=4
m=4-2/6-3
m=2/3.
Now let us check the equation with greatest slope
(a) y=5/7x
5/7 > 2/3
(b) y=3/5x
3/5 < 2/3
(c) y=1/3x
1/3 < 2/3
(d) y=7/9x
7/9 > 2/3
(e) y= 7/11x
7/11< 2/3
Hence (a) y=5/7x and (d) y=7/9x have a greater unit rate than the rate represented in the table.
