If -2i is a root, then 2i is also a root. If √10 is a root, then -√10 is also a root. Convert all four of these roots into factors using the factor theorem (which says that if R is a root, then (x - R) is a factor).
(x + 2i) (x - 2i) (x - √10) (x + √10)
Multiply these factors together. (It's easiest to multiply the conjugate pairs together first.):
x^4 - 6x^2 - 40
Answer:
9 inches
Step-by-step explanation:
Since the triangle are similar then the ratios of corresponding sides are equal
let x be the longer median, then
=
( cross- multiply )
16x = 6 × 24 = 144 ( divide both sides by 16 )
x = 9
The value of this car when it is 9 years old is equal to $16,757.00.
<h3>How to calculate the value?</h3>
In order to determine the value of this car when it is 9 years old, we would use an exponential function which also relates to compound interest as follows:
A = P(1 - r)^t
Substituting the given parameters into the formula, we have;
A = 32,200(1 - 0.07)^9
A = 32,200(0.93)^9
A = 32,200 × 0.5204
A = $16,757.00.
