What is the derivative of sqrt7 times x +sqrt2x
castortr0y [4]
I guess you mean the derivative of:

√7x + √2x, if so then:

Remember that the derivative of √u = 1/(2√u) . u'

if 7x = u, then u' = 7 , hence the derivative of √7x is 7/(2√7x)
Use same logic for √2x and you will find:

y' = 7/(2√7x) + x/√2x

Mr. Williams is building a sand box for his children. It cost $228 for the sand if he builds a regular-sandbox with dimensions 9
erastovalidia [21]

Answer:

It will cost $512.73

Step-by-step explanation:

9 in by 6 in sandbox cost $228

i.e., 9*6 = 54 in²

54 in² cost $228

1 in² will cost $228/54

≈ $4.22

If the new dimension is 13 1/2 in by 9 in

then area will be 13 1/2*9

27*9/2 = 121.5 in²

The cost of 121.5 in² will be

121.5*4.22 = $512.73
