Answer:

x = 5, x = 11

Step-by-step explanation:

Set f(x) = 0 and solve for x.

0 = (x -8)² -9

9 = (x -8)² . . . . . add 9

±√9 = x -8 . . . . . take the square root

±3 +8 = x . . . . . . . add 8

That is, ...

x = 8 -3 = 5 . . . . lesser x

x = 8 +3 = 11 . . . greater x

Answer:

y = -3x + 60

Step-by-step explanation:

For the answer to the question above,

let x = number of weeks let y = amount of waste.

The linear equation may be expressed as,y = mx + b

m and b are the slope and y - intercept, respectively. Substituting the corresponding values,

(Week 5) 45 = 5m + b

(Week 10) 30 = 10m + b

Solving for m and b gives the values as m = -3 and b = 60. Thus, the equation is

y = -3x + 60

2. Write an expression to represent f (20)

Furkat [3]

Answer:

I just learned this topic and have the same question, so I'm not sure if this right. However, I see a fellow student struggling and have to at least put in what I know. My equation was f(n) = 64(1/2)^n-1, then the question was write an expression to represent f(20).

Step-by-step explanation:

So, my answer was f(20) = 64(1/2)^19

f(20) is the number you plug into n. And because the exponent is n-1, I knew to subtract 1 from 20 to get 19.

Then I just wrote the equation out like the original expect with the numbers pluged in: f(20) = 64(1/2)^19

I hope this helps!

1. A store manager marked up the price of a $12 clock by 20%. What is the new price of the clock?

Anon25 [30]

Answer:

1) new price of the clock is $14.4

2) Kyra scored 70% marks

3) 43.75% students are not eighth graders

Step-by-step explanation:

1. A store manager marked up the price of a $12 clock by 20%. What is the new price of the clock?

Price of Clock = $12

Mark up = 20%

We need to find new price of clock.

The price of clock can be found by finding 20% of 12 and then adding that amount in original price.

So, finding 20% of 12

$20\% of 12 \\=\frac{20}{100}\times 12\\=2.4$

So 20% of 12 is 2.4

Now finding new price:

New Price = Actual Price + Mark up

New Price = 12 + 2.4

New Price = 14.4

So, new price of the clock is $14.4

2. On a math quiz, Kyra answered 7 of 10 questions correctly. Express her quiz score as a percent.

Total questions = 10

Correct answers = 7

We need to express her quiz score as percent

It can be found using formula: $Percent Score = \frac{Obtained\:Marks}{Total\:Marks}\times 100\%\\$

Putting values and finding percentage

$Percentage = \frac{Obtained\:Marks}{Total\:Marks}\times 100\%\\\\Percentage = \frac{7}{10}\times 100\%\\Percentage = 70\%$

So, Kyra scored 70% marks

3. 96 students are enrolled in the Dance Program at Castillero. Of those students, 54 are eighth-graders. The remaining students are 6th or 7th graders. What percentage of the students are not eighth graders?

Total Students = 96

Number of eighth-graders students = 54

Remaining students = 96 - 54 = 42

So, 42 students are 6th or 7th graders

We need to find percentage of the students are not eighth graders.

$\frac{42}{96}\times 100\%\\=43.75\%$

So, 43.75% students are not eighth graders
