Step-by-step explanation:
If Sarah makes a profit of $ 4 on every necklace she sells, then:
4 necklaces = 4 * 4 = $ 16
6 necklaces = 6 * 4 = $ 24
8 necklaces = 8 * 4 = $ 32
10 necklaces = 10 * 4 = $ 40
<u>The correct table is A.</u>
Answer:
F and D
Step-by-step explanation:
When a negative number is multiplied by a positive number, the result is a negative number. When a negative number is multiplied by another negative number, the result is positive.
Let the total amount that Sarah deposited be $x
using the annuity formula:
A=P[((1+r)^n-1)/r]
A=future value
r=rate
n=number of years
from the information given:
A=$500000
r=2.75%
n=65-42=23 years
p=$x
thus plugging our values in the formula we get:
500000=x[((1+0.0275)^(23)-1)/(0.0275)]
500000=31.50x
x=15,872.04883
She deposited 15,873.04883 per year
The monthly deposit will therefore be:
15873.04883/12=$1322.67
I honestly don’t know but I hope you find the answer to this question soon and have a good night good luck
If the matrix is of 2 by 2 then we can find the determinant of the matrix.
Then (ad - bc ) gives you the determinant of the matrix.
For example,
= (2)(-2) - (1)(4)
= - 4 - 4
= -8
