What is the rule input numbers are 17 18 _ 28

How do I solve it. I don't understand where I should start the problem I have the formulas

Luda [366]

V=length times width times height
wait, we need it in yards
3ft=1yard
so height=1

v=45 times 30 times 1
v=1350 cubic yards
1 cubic yard=201.974 gallons
so times both sides by 1350
272664.9 gallons
per every 5000 gallons of water we have 1 of chlorine
so 272664.9/5000=54.53298
so we need about 54.5 gallons or 55 gallons of cholrine

A spinner and 6 cards are shown below:

Tems11 [23]

Answer:

1 over 18

Step-by-step explanation:

The spinner has 3 segments and he spun it 1 time. So, he has a 1 in 3 chance of landing on green.

There are 6 cards so he has a 1 and 6 chance of picking up the yellow card.

Multiply those and you have 1 over 18

Done!

Answer:

2. 92 ounces of Sprite

3. 1/6 do not want mustard on their ham sandwiches

4. 6 hours playing volleyball

5. 32 portions

Step-by-step explanation:

2. Sam has 8 cans of Sprite. Each can is 11 2/4 ounces

We can simplify 2/4 to 1/2

Multiply the number of cans by the ounces per can

8 * 11 1/2

8 * 11.5

92 ounces

3. 1/2 of the students want ham. 1/3 of those do not want mustard

We multiply 1/2*1/3 = 1/6

1/6 of the students do not want mustard on their ham sandwiches

4. 8 hours at the beach. 3/4 of the time was spent playing volleyball

Multiply this together

8*3/4 = 8/4*3 = 2*3 = 6 hours

5. We have 4 lbs of wings. We divide it into 1/8 lbs parts

4 ÷ 1/8

Copy dot flip

4 * 8/1

32 portions

Find number a and k so that x-2 is afactor<br>OF F(x)=x4-2ax tax-<br>X+k and F(-1)=3

Slav-nsk [51]

Question:

Find numbers a and k so that x-2 is a factor of

$f(x)=x^4-2ax^3+ax^2- x+k$

and

$f(-1)=3$

Answer:

$k = -2$ and $a=1$

Step-by-step explanation:

Given

$f(x)=x^4-2ax^3+ax^2- x+k$

$Factor:\ x - 4$

$f(-1)=3$

Required

Find a and k

For $f(-1)=3$

Substitute -1 for x

$f(x)=x^4-2ax^3+ax^2- x+k$

$f(-1) = (-1)^4 - 2a *(-1)^3 + a*(-1)^2 - (-1) + k$

$f(-1) = 1 - 2a *-1 + a*1 +1 + k$

$f(-1) = 1 +2a + a +1 + k$

$f(-1) = 2 +3a + k$

Substitute 3 for f(-1)

$3 = 2 +3a + k$

Collect Like Terms

$3 - 2 = 3a + k$

$1 = 3a + k$

Also:

If $x - 2$ is a factor, then

$f(2) = 0$

Substitute 2 for x and 0 for f(x)

$f(x)=x^4-2ax^3+ax^2- x+k$

$0 = 2^4 - 2a * 2^3 + a * 2^2 - 2 + k$

$0 = 16 - 2a * 8 + a * 4 - 2 + k$

$0 = 16 - 16a + 4a - 2 + k$

$0 = 16 - 12a - 2 + k$

Collect Like Terms

$2 - 16 = - 12a + k$

$-14 = k - 12a$

$k = 12a - 14$

Substitute 12a - 14 for k in $1 = 3a + k$

$1 = 3a + 12a - 14$

$1 = 15a - 14$

Collect Like Terms

$15a = 1 + 14$

$15a = 15$

Solve for a

$a = \frac{15}{15}$

$a=1$

Substitute 1 for a in $k = 12a - 14$

$k = 12 * 1 - 14$

$k = 12 - 14$

$k = -2$
