a) (f+g)(x) = f(x) + g(x) = -4x + 5x = x

b) -9(x) = -9x? I have no idea what this means.

c) (f o g)(x) = (f(g(x)) = f(5x) = -4 (5x) = -20x

Rewrite the function by completing the square. h(x)= 4 x^{2} -36 x +81

noname [10]

Answer:

4(x-4.5)^2

Step-by-step explanation:

h(x)=4x^2-36x+81

=4(x^2-9x)+81

=4(x^2-9x+20.25)-(4)(20.25)+81

=4(x-4.5)^2

A binomial distribution

Alina [70]

Answer:

0.324

Step-by-step explanation:

Given that :

Success rate = 30%

p = 30% = 0.3

q = 1 - p = 1 - 0.3 = 0.7

Number of trials, n = 6

Probability of having exactly 2 successes ; x = 2

P(x = 2)

Usibgbtge binomial probability relation :

P(x = x) = nCx * p^x * q^(n-x)

P(x = 2) = 6C2 * 0.3^2 * 0.7^4

P(x = 2) = 15 * 0.3^2 * 0.7^4

P(x = 2). = 0.324135

P(x = 2) = 0.324

How much would $300 invested at 4% interest compounded monthly be

Anna11 [10]

Answer:

$412.92

Step-by-step explanation:

You are going to want to use the compound interest formula, which is shown below.

$A=P(1+\frac{r}{n} )^{nt}$

P = initial balance

r = interest rate

n = number of times compounded annually

t = time

The first step is to change 4% into its decimal form:

4% -> $\frac{4}{100}$ -> 0.04

Now plug in the values:

$A=300(1+\frac{0.04}{12})^{(12)8}$

$A=412.92$

It would be worth $412.92
