<h3>Weight of 9 empty water bottles is 2.8926 pounds</h3>

<em><u>Solution:</u></em>

Given that,

14 empty water bottles weigh 4.5 pounds

<h3><u>Find the weight of 1 empty bottle</u></h3>

$\text{weight of 1 empty bottle } = \frac{4.5}{14}\\\\\text{weight of 1 empty bottle } = 0.3214\ pounds$

<h3><u>what will 9 empty water bottles weigh?</u></h3>

Weight of 9 empty bottles = 9 x weight of 1 empty bottle

Weight of 9 empty bottles = 9 x 0.3214

Weight of 9 empty bottles = 2.8926

Thus weight of 9 empty water bottles is 2.8926 pounds

Given the function f(x)=-2x^2+6x ,then what is f(x)=−3 as a simplified polynomial?

GenaCL600 [577]

The given function, f(x) = -3, written as a simplified polynomial is 2x² - 6x- 3 = 0

<h3>Simplified Polynomials</h3>

From the question, we are to determine f(x) = -3 as a simplified polynomial

From the given information, we have that

f(x) = -2x^2 + 6x

Rewrite the the given equation properly.

Rewriting, we get

f(x) = -2x² + 6x

Also, from the given information

We have that

f(x) = -3

Thus, we can write that

- 3 = -2x² + 6x

Writing the above equation as a simplified polynomial, we get

- 3 = -2x² + 6x

2x² - 6x- 3 = 0

Hence, the given function, f(x) = -3, written as a simplified polynomial is 2x² - 6x- 3 = 0

During a certain day, a worker made 81 parts. He usually does 45 parts per day. What was the percent by which he increased the n

Lana71 [14]

Answer:

The answer is 80%.

Step-by-step explanation:

During a certain day, a worker made 81 parts.

He usually does 45 parts per day.

Number of extra parts made = $81-45=36$

The percent by which he increased the number of parts he usually makes can be given as = $\frac{36}{45}\times100$ = 80%

Therefore, on that day, the percent increased by 80%.

The money collected from selling bacon at a butcher store is given by the function f(x) = 3.55x – 4, where f(x) is the sales rev

Molodets [167]

F(x) = 3.55x - 4...17 customers....17 = x
f(17) = 3.55(17) - 4 =
f(17) = 60.35 - 4 =
f(17) = 56.35

f(x) = 3.55x - 4...21 customers....21 = x
f(21) = 3.55(21) - 4 =
f(21) = 74.55 - 4 =
f(21) = 70.55

ok...I think u can see how I am doing this...answer should be easy to find..lol
