Hello,

d f(x²-1)/dx=f'(x²-1)*2x
if x=2 then f'(2²-1)*2*2 =f'(3)*4=-4*4=-16

Answer A

If you need explains:

let's y=x²-1

df(x²-1)/dx=df(y)/dy*(dy/dx)=f'(x²-1)*2x

3 - x/2 = 6 (Solve each equation) Check your answer

Yanka [14]

Answer to question
3-x/2=6
Subtract 3 from both sides
-x/2=3
Multiply 3 by -2
Final Answer: x=-6

Work check
3-x/2=6
Substitute -6 for x since you solved for x in the last equation
3-(-6)/2
Convert 3-(-6/2) to 3+6/2
3+6/2
Divide 6 by 2
3+3
Add
Final Answer: 6 (This 6 is the same 6 we used to solve for x in the first equation).

If a hallway measuring 90 feet by 7 feet requires 1/2 a fluid ounce of cleaning solution per square foot, how much cleaning solu

kirill115 [55]

90ft by 7ft gives an area of:
90 x 7 = 630 sq ft

1/2 fl oz is needed for each square foot

630 x 1/2 = 315 fl oz required.

Suppose f is a function with exponential growth and f(0)=1. Explain why f can be represented by a formula of the form

galben [10]

We are supposed to explain why the given function can be expressed in form $f(x)=b^{x}$ , when $f(0)=1$ .

Since the given function is an exponential function we can express it as $f(x)=a(b)^{x}$ .

Now let us substitute x=0 in the given function,

$f(x)=b^{x}$

$f(0)=b^{0}$

$f(0)=1$

Let us substitute x=0 in our function.

$f(0) = a(b)^{0}$

$f(0) = a\cdot 1$

$f(0)=a$

Upon substituting a=1 in our function we will get,

$f(x) = 1(b)^{x}$

$f(x) =(b)^{x}$

Therefore, our function f can be represented by the formula of the form $f(x)=b^{x}$ .

Solve the problem.

Lorico [155]

Answer:

Step-by-step explanation:

You must use a combination:

$_nC_k=\dfrac{n!}{k!(n-k)!}$

We have <em>n = 16</em>, <em>k = 3</em>.

Substitute:

$_{16}C_3=\dfrac{16!}{3!(16-3)!}=\dfrac{13!\cdot14\cdot15\cdot16}{2\cdot3\cdot13!}\qquad\text{cancel}\ 13!\\\\=\dfrac{14\cdot15\cdot16}{2\cdot3}=\dfrac{7\cdot5\cdot16}{1}=560$
