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:
A. 106
Step-by-step explanation:
Given function that represents the cost of materials to make x shirts,
Also, the function for the selling price of x shirts,
Where,
From equation (1),
( From equation (2) )
For 18 shirts, i.e. x = 18
The selling price would be,
Option 'A' is correct.
Money (y) (hundreds of dollars) 15 30 45 60 75 90
Identify the function that represents Elliot's savings and the amount that Elliot will have saved in 9 years.
(A)y = 15x, in 9 years he will have saved $13,500
(B)y = x + 15, in 9 years he will have saved $2,400
(C)y = 6x, in 9 years he will have saved $5,400
(D)y = x + 90, in 9 years he will have saved $9,900
