<h2>
The all roots are equation are 1, - 1 and - 2.</h2>
Step-by-step explanation:
The given cubic polynomial:
k(x) = + 2 - x -2
To find, the all roots are + 2 - x -2 = ?
∴ k(x) = + 2 - x -2
⇒ + 2 - x -2 = 0
⇒ (x + 2) - 1(x + 2) = 0
⇒ ( - 1)(x + 2) = 0
⇒ - 1 = 0 and x + 2 = 0
⇒ - 1 = 0
⇒ = 1
⇒ x = ± 1 = 1, - 1
or, x + 2 = 0
⇒ x = - 2
Thus, the all roots are equation are 1, - 1 and - 2.
Final amount that Kate wants to have (A) = $25000
Time for which the money needs to be invested (T) = 16 years
Rate of interest that Kate will get per year (R) = 6%
Let us assume the principal amount (P) = x
Then
A = P (1 + RT)
25000 = x[1 + {(6/100) * 16}]
25000 = x[1 +(96/100)]
25000 = x[196/100]
196x = 25000 * 100
x = 2500000/196
= 12755.10 dollars
So the principal amount that needs to be invested is $12755.10.
Answer:
4.33 x 10^6
Step-by-step explanation:
2.3 * 10^5
+ exponent move to the right
2.3 = 230000
4.1 * 10^6
+ exponent move to the right
4.1 = 4100000
230000 + 4100000 = 4330000
4330000 in notation form is...
4.33 x 10^6
Recheck your work by
4.33 x 10^6
+ exponent move to the right
4.33 = 4330000
4.33 x 10^6
Hope this helps.
By completing the experiment a few more times and combining the results to the trails already done
Hope this helps you!! xD
