Answer:
A valid will has to be in writing, and signed by the testator in the presence of two witnesses, who must also attest the will. If the process is not followed to the hilt, the will can be challenged in the court of law. So the answer is true.
Simplifying
(2a + 5)(3a + -4) = 0
Reorder the terms:
(5 + 2a)(3a + -4) = 0
Reorder the terms:
(5 + 2a)(-4 + 3a) = 0
Multiply (5 + 2a) * (-4 + 3a)
(5(-4 + 3a) + 2a * (-4 + 3a)) = 0
((-4 * 5 + 3a * 5) + 2a * (-4 + 3a)) = 0
((-20 + 15a) + 2a * (-4 + 3a)) = 0
(-20 + 15a + (-4 * 2a + 3a * 2a)) = 0
(-20 + 15a + (-8a + 6a2)) = 0
Combine like terms: 15a + -8a = 7a
(-20 + 7a + 6a2) = 0
Solving
-20 + 7a + 6a2 = 0
Solving for variable 'a'.
Factor a trinomial.
(-5 + -2a)(4 + -3a) = 0
Subproblem 1
Set the factor '(-5 + -2a)' equal to zero and attempt to solve:
Simplifying
-5 + -2a = 0
Solving
-5 + -2a = 0
Move all terms containing a to the left, all other terms to the right.
Add '5' to each side of the equation.
-5 + 5 + -2a = 0 + 5
Combine like terms: -5 + 5 = 0
0 + -2a = 0 + 5
-2a = 0 + 5
Combine like terms: 0 + 5 = 5
-2a = 5
Divide each side by '-2'.
a = -2.5
Simplifying
a = -2.5
Subproblem 2
Set the factor '(4 + -3a)' equal to zero and attempt to solve:
Simplifying
4 + -3a = 0
Solving
4 + -3a = 0
Move all terms containing a to the left, all other terms to the right.
Add '-4' to each side of the equation.
4 + -4 + -3a = 0 + -4
Combine like terms: 4 + -4 = 0
0 + -3a = 0 + -4
-3a = 0 + -4
Combine like terms: 0 + -4 = -4
-3a = -4
Divide each side by '-3'.
a = 1.333333333
Simplifying
a = 1.333333333
Solution
a = {-2.5, 1.333333333}
Answer:
<em>a. 22.64%</em>
Explanation:
At first we are going to need to compute the Internal rate of return(IRR) (in which the current value of inflows = the current value of outflows)
Let's let the IRR be <em>x percent</em>
Therefore $4,500 = $750 / (1.0x)
+ $1,000 / (1.0x) <em>power 2</em> + $850 / (1.0x) <em>power 3 </em>
+ $6,250 / (1.0x) <em>power 4</em>
Thus, x = approximate return rate = <em>22.64 percent</em>
Answer: The complete table is as follows:
Explanation:
The following are the formulas for calculating marginal product , total revenue and marginal revenue product:
Marginal product = 
Total revenue = Price × Quantity
Marginal revenue Product = Marginal product × Price
By using these formulas, I have completed the following table:
