Answer:

c

Step-by-step explanation:

The prime factorization of 450 is 2 × 3 × 3 × 5 × 5. Written with exponents, the answer is 2 × 32 × 52.

It expresses 450 as a product of prime factors: 450 = 2 x 3 x 3 x 5 x 5. The correct answer is option C.

Prime Factorization is defined as any number that may be expressed as a product of prime numbers that has been said to be prime factorized. Any integer with exactly two factors 1 and the number itself. is said to be a prime number.

The given number is as follows:

450

We need to write 450 as the product of its prime factors, which is 450.

⇒ 450 = 2 x 3 x 3 x 5 x 5

Hence, it expresses 450 as a product of prime factors: 450 = 2 x 3 x 3 x 5 x 5.

Therefore, the correct answer is option C.

Answer:

A,B,C,F

Step-by-step explanation:

The correct answer would be options (A), (B), (C), and (F)

(A) positive: (–2, 2)

(B) range: (–3, 4]

(C) domain: (–3, 3]

(F) increasing: (–3, –1)

The domain of the function includes all possible x values of a function, and the range includes all possible y values of the function.

The vertical span of the range is from y > -3 to y = 3. The interval for this is [(-3, 3].

The horizontal range, from x > -3 to x = +4, represents the domain. This is represented by the interval [(-3, 4].

The graph decreases to the right, it gets smaller. There is no mention of the endpoints. The x values are in the range (-1, 4).

The graph is increasing where it goes up to the right. The endpoints are generally not included. The x-values are in the interval (-3, -1).

The region of the graph that is above the x-axis is positive. The interval contains x. (-2, 2).

Answer:

f^-1(x) = x - 5

Step-by-step explanation:

f(x) = x + 5

y = x + 5

x = y + 5

y = x - 5

f^-1(x) = x - 5

Answer:

f^ -1(x) = x - 5

Step-by-step explanation:

y =x+5

To find the inverse, exchange x and y

x = y+5

Solve for y

Subtract 5 from each side

x-5 = y+5-5

x-5 = y

The inverse is  x-5

Answer: Jesse

because i guess i divided the number you could do it however 15 divided by 2 = 7.5 and 26 divided by 5 = 5.2

Answer:

Jesse is the slower rate.

Step-by-step explanation:

The slower rate is going to be determined by the distance divided by the time.

Jesse: 26 / 5 = 5.2 miles / hour

Answer:

y = 5x + 28

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 5 , thus

y = 5x + c ← is the partial equation

To find c substitute (- 6, - 2) into the partial equation

- 2 = - 30 + c ⇒ c = - 2 + 30 = 28

y = 5x + 28 ← equation of line

Answer:

Step-by-step explanation:

f(x)=x² - 2x + 7

To find f(-3) substitute the value of x that's - 3 into f(x). That is for every x in f (x) replace it with - 3

We have

f(-3) = (-3)² - 2(-3) + 7

= 9 + 6 + 7

We have the final answer as

f(-3) = 22

Answer:

Options (1) and (2)

Step-by-step explanation:

Properties of a polynomial,

1). A polynomial having division by a variable can't be defined as a polynomial.

  Example:

   (y² + [tex]\frac{x}{1+x}[/tex])

2). A polynomial can't have a negative exponent.

  Example : [tex](x^{-2}+y-6)[/tex]

3). Polynomials don't have the radicals.

  Example : y² + x√3

4). A polynomial can't have a fraction exponent.

   Example : [tex]x^2+x^{\frac{1}{2}}-1[/tex]

By these properties, Options (3) and (4) are not the polynomials.

Options (1) and (2) are the correct options.

Answer & Step-by-step explanation:

Assuming that there is a constant rate of change, we can use the equation:

[tex]y=kx[/tex]

k is the constant rate of change. Set up an equation in which the pounds are determined by the rate of change between kilograms and pounds:

[tex]1=k(2.2)[/tex]

Isolate the variable k:

[tex]\frac{1}{2.2}=\frac{k(2.2)}{2.2}\\\\\frac{1}{2.2}=k[/tex]

Set up another equation like so:

[tex]\frac{y}{x}=\frac{y}{x}[/tex]

Insert values:

[tex]\frac{1}{2.2}=\frac{y}{112}[/tex]

Solve for y. Cross multiply:

[tex]1(112)=2.2y\\\\112=2.2y[/tex]

Isolate the variable. Divide both sides by 2.2:

[tex]\frac{112}{2.2}=\frac{2.2y}{2.2} \\\\ y=50.9090...[/tex]

So, there are about 50.9 kilograms in 112 pounds.

Answer:

[tex]99 + 50x = 549[/tex]

Alternatively you can write it as;

[tex]50x - 450 = 0[/tex]

Step-by-step explanation:

One time service fee=$99

Rate of service=$50/hour

let unknown hours=x

Therefore the equation is

[tex]99 + 50x = 549[/tex]

or you can further simplify it to:

[tex]50x - 450 = 0[/tex]

And you can then solve for x to be 9 hours.

Answer:

25%

Step-by-step explanation:

If you start at 45% and it reduces by 20% you are just doing 45-20 which equals 25. (Please let me know if im wrong)

16 percent markup is the new retail price over the manufacturer price.

Here,

A store sells candles.

Retail price will be 45% marked-up

A month later, store reduced the retail price of the candles by 20%.

We have to find the percent markup.

What is the percentage?

The percentage is the value per hundred.

Now,

Consider the manufacturer price = 100x

Retail price will be 45% marked-up

Hence,  100x+45% of 100x = 145x

Reduced retail price of the ladder after one month = 145x-145x*20/100

Reduced retail price of the ladder after one month = 116x

Percentage markup of the reduced retail price over the manufacturer price will be:

={(reduced retail price - manufacturer price)/manufacturer price} *100

=[ (116x-100x)/100x ] *100 = 16%

Hence, 16 percent markup is the new retail price over the manufacturer price.

Answer:

For question 2 the slope is 1. So what you do is get the points you need to put on the graph and move them up one. Like how you did on question 1.

(0.5, 5) (1, 10) (1.5, 15) (2, 20) (2.5, 25)

Question 3 is the same thing but the slope is now 2. Then you would have to pin the points as...

Answer:

1) I went shopping and I saw a dress and i went to the check out line and the lady told me that my total with be 30 dollars

2) It was my birthday and i took all my birthday cards and i counted all my money i got.. the total was 30$.

Step-by-step explanation:

Answer:

1) 5 limes, 5 lemons, 1,000 mL of pineapple juice, 2,000 mL of lemonade, 1,000 of orange juice

2) Limes = $2, Lemons = $2.5, Lemonade = $1.60, Orange Juice = 80c, Pineapple Juice = 90c

Step-by-step explanation:

1/2 limes · 10 = 5

1/2 lemons · 10 = 5

100 mL of pineapple juice · 10 = 1,000 mL

200 mL of lemonade · 10 = 2,000 mL

100 mL of orange juice · 10 = 1,000 mL

Cost:

5 limes · 0.4 = $2

5 lemons · 0.5 = $2.5

mL to L

1,000 mL of pineapple juice = 1 L, this costs 90¢

2,000 mL of lemonade = 2 L, this costs $1.60

1,000 mL of orange juice = 1 L, this costs 80¢

Overall:

5 limes for $2

5 lemons for $2.5

1 L of of pineapple juice for 90¢

2 L of lemonade for $1.60

1 L of orange juice for 80¢
