Solve the formula A=law for l

Volgvan

Answer:

l = A/aw

Step-by-step explanation:

Since we want the equation in terms of l, we simply isolate the l by dividing both sides by aw:

A = law

A/aw = law/aw

A/aw = l

F’(x)= 1+3 square root x f(9)=68

notka56 [123]

Answer:

$f(x) = x + 2x^\frac{3}{2} + 5$

Step-by-step explanation:

I'm assuming the question here is asking for f(x)

The first step would be to find the antiderivative of f'(x)

$\int{1+3\sqrt{x}} \, dx = \int{1 + 3x^\frac{1}{2}} dx$

Apply the reverse power rule

$x + 2x^\frac{3}{2} + C$

Now solve for C when x = 9

$x + 2x^\frac{3}{2} + C = 68\\9 + 2(9)^\frac{3}{2} + C = 68\\9 + 2(27) + C = 68\\9 + 54 + C = 68\\63 + C = 68\\C = 5$

Now substitute into the antiderivative

$f(x) = x + 2x^\frac{3}{2} + 5$

a company owner has 20 employees, and plans to give bonuses to 6 of them. How many different sets of employees could receive bon

Leviafan [203]

Answer: 38760

Step-by-step explanation:

Given : The number of employees in the company = 20

The number of employees will be selected by company owner to give bonus = 6

We know that the combination of n things taking r at a time is given by :-

$^nC_r=\dfrac{n!}{r!(n-r)!}$

Then, the number of different sets of employees could receive bonuses is given by :-

$^{20}C_6=\dfrac{20!}{6!(20-6)!}\\\\=\dfrac{20\times29\times18\times17\times16\times15\times14!}{(720)14!}=38760$

Hence, the number of different sets of employees could receive bonuses is 38760.
