Answer:
8x * sqrt(5x)
Step-by-step explanation:
Factor 320 into its prime factors: (2^6) * 5
To simplify sqrt we extract factors which are squares and the rest remain inside the root: (2^6) will be extracted (2^6=64) and 5 will remain inside
Take sqrt of factors being extracted: sqrt64= 8
Now it looks like this: 8 * sqrt(5x^3)
SQRT(x^3) is the same as x * SQRT(x)
Therefore, sqrt (320x^3)= 8x*sqrt(5x)
Answer:
31
Step-by-step explanation:
16+5=21
21+5=26
26+5=31
The cash price would be lower. A further explanation is below.
According to the question,
Interest rate per month,
(%)
hence,
The Present value of the monthly payment will be:
=
=
=
As we can see that the cash price is 15,999. Thus the above answer is right.

Answer:
Cash price
Step-by-step explanation:
The computation is shown below:
The Interest rate per month (r) = (9% ÷ 12) = 0.75%
Now Present value of the monthly payment is
= PMT × {[(1 + rate of interest)^number of years - 1] ÷ rate of interest}
= 1,499 × {[(1 + 0.75%)^12 - 1] ÷ 0.75%}
= 18,748.89
And the cash price is 15,999
So, the cash price would be lower
Answer:
C = .9423
Step-by-step explanation:
i took the test and got it right.
–6x + 4y = 0
A.
(2, 3)
B.
C.
(5, 1)
D.
(–2, –3)
2x + 3y = 13
–6x + 4y = 0
multiply the first equation by 3
6x +9y = 39
then add the 2nd equation to the first
6x +9y = 39
–6x + 4y = 0
-------------------
13y = 39
divide by 13
y =3
now take an equation and solve for x by substituting in y
2x +3y =13
2x +3(3) =13
2x+9 =13
subtract 9 from each side
2x =4
divide by 2
x=2
