Find all real zeros of the function.
f(x)=4(x^2-1)(x-3)(x+3)^2

Answers

Answer 1

Answer: 4(x^2 - 1)(x - 3)(x + 3)^2 = 0
(x + 1)(x - 1)(x - 3)(x + 3) = 0
x = -1, 1, 3, -3

we have

$f(x)=x^(2)-2x-3$

Find the roots

Equate the function to zero

$x^(2)-2x-3=0$

Group terms that contain the same variable, and move the constant to the opposite side of the equation

$x^(2)-2x=3$

Complete the square. Remember to balance the equation by adding the same constants to each side.

$x^(2)-2x+1=3+1$

$x^(2)-2x+1=4$

Rewrite as perfect squares

$(x-1)^(2)=4$

Square root both sides

$(x-1)=(+/-)2$

$x=1(+/-)2$

$x=1+2=3$

$x=1-2=-1$

therefore

the answer is

$x=3$

x^2 -2x -3 = 0

(x-3)(x+1)=0

x+1=0
x=-1

x-3=0
x = 3

so the missing number is 3

A bacteriologist estimates that there are 5.2×10^4 bacteria growing in each of 20 petri dishes. About how many bacteria in total are growing in the petri dishes? Express your answer in scientific notation

Answers

Answer:

1X10^6

1.04x10^6

Step-by-step explanation:

You start by multiplying 5.2x10^4 by 20 because there are 20 petri dishes with this amount growing, and you get 1,040,000. Now we need to convert it to scientific notation. We know that 1,000,000 is 10^6, so we would move the decimal to the left 6 places and get 1.04x10^6. This is in scientific notation, but we need to keep in mind significant figures (sig figs), so your final answer would be 1x10^6, if that is not what your instructor is looking for, try 1.04x10^6.

Final answer:

The total amount of bacteria growing in the 20 petri dishes is calculated by multiplying the amount of bacteria in each dish (5.2×10^4) by the number of dishes (20), which gives a result of about 1.04×10^6 bacteria.

Explanation:

Given that there are approximately 5.2×10^4 bacteria in each dish and there are 20 petri dishes, we can find the total amount of bacteria by multiplying these two values together. The calculation is as follows: 5.2×10^4 bacteria/dish * 20 dishes = 1.04×10^6 bacteria. Therefore, there are about 1.04×10^6 bacteria in total growing in the petri dishes.

If you invest $2,000 today in a bank that gives you a 4 percent annual interest rate, which of these items can you buy in seven years?

Answers

Just the Mountain bike, cause 4% of $2000 is, $80. and $80 for each year for 7 years make $560. now after 7 years your bank account has $2560. Therefore, you can buy a mountain bike, and have $60 left over, if there is no tax included. But if there is tax, your going to be still short by $115.(calculated according to florida's tax, that is 7%.) Anyways if the tax is over 2% you cant get that bike.

All of them

put this in a calculator: 2000*20%*7 then take away the prices or bills and thats how much money is left after the shopping spree

What is the value of 6P6? A.1 B.36 C.720 D.46,656

Answers

$the\ permutationon:\ \ n\ P\ x= (n!)/((n-x)!) \n \n6\ P\ 6= (6!)/((6-6)!) = (6!)/(0!)= (2\cdot3\cdot4\cdot5\cdot6)/(1)=720$

$Ans.\ C$

The value of 6P6 permutation is 720 .

To calculate the value of 6P6 ( permutation of 6 objects taken 6 at a time ), we can use the formula :

nPn = n !

where n is the total number of objects .

In this case, n = 6. So, substituting it into the formula :

6P6 = 6 !

Calculating the factorial of 6 :

6! = 6 × 5 × 4 × 3 × 2 × 1

= 720

Therefore, the value of 6P6 is 720 .

Hence, the correct answer is C . 720 .

17 were adults

Step-by-step explanation:

bunny and rabbit problems

if they were all adults

7 x 47 = 329

329 - 269 = 60

60/ (7-5) = 30
