ASAP!! Please help me. I will not accept nonsense answers, but will mark as BRAINLIEST if you answer is correctly with solutions

Sedaia [141]

Answer:

f(x) = 2(x –3)²

Step-by-step explanation:

f(x) = 2x² – 12x + 18

The vertex form of the above expression can be obtained as follow:

f(x) = 2x² – 12x + 18

Factorise

f(x) = 2(x² – 6x + 9)

Next, we shall simplify x² – 6x + 9 by factorisation method.

This is illustrated below:

x² – 6x + 9

Multiply the first term i.e x² and last term i.e 9 together. The result is 9x².

Next, find two factors of 9x² such that their sum will result to the 2nd term i.e –6x in the expression above.

The factors are –3x and –3x

Next, replace –6x with –3x and –3x in the equation above as shown below:

x² – 6x + 9

x² – 3x –3x + 9

Factorise

x(x – 3) –3(x –3)

(x –3)(x –3)

(x –3)²

f(x) = 2x² – 12x + 18

f(x) = 2(x² – 6x + 9)

f(x) = 2(x –3)²

Therefore, the vertex form of the function f(x) = 2x² – 12x + 18 is

f(x) = 2(x –3)²

An online furniture store sells chairs for $150 each and tables for $400 each. The store must sell a minimum of $4900 worth of c

Snowcat [4.5K]

Answer: 150c + 400t ≥ 4900

Step-by-step explanation:

Let the number of chairs sold = c

Let the number of tables sold = t

Price for each chair = $150

Price for each table = $400

The inequality that could represent the number of tables and chairs sold will be:

(150 × c) + (400 × t) ≥ 4900

150c + 400t ≥ 4900

Joy knits a square blanket that has an area of 1,500 square inches . What is the approximant length for each side of the blanket

Alex777 [14]

Answer:

1) Option C - 39 inches

2) Option C - 12167 cubic feet

Step-by-step explanation:

1) Given : Joy knits a square blanket that has an area of 1,500 square inches

To find : What is the approximate length for each side of the blanket.

Solution: Area of square = 1500 square inches

Let the side of the blanket = s

Formula of area of square is $A= s^2$

$1500= s^2$

$s= \sqrt{1500}$

$s=38.7$

Approximately Side of blanket = 39 inches

Therefore, Option C is correct.

2) Given : Jeff is an architect and is drawing the plan for a room addition for a client. If the shape of the room is a cube.

To find : what is the volume in cubic feet if the length is 23 feet?

Solution: Length of side of a cube (a)= 23 feet

Let the volume of a cube = V

Formula of Volume of cube is $V= a^3$

$V= (23)^3$

$V= 12167$

Volume of a cube = 12167 cubic feet

Therefore, Option C is correct.

How do you know the number of part to divide a number line from 0 to 1 into when comparing fractions

Katyanochek1 [597]

To compare fractions you need a common denominator, then you can make a comparison. You would divide the number line between 0 and 1 (or any 2 whole numbers on the number line) based on that common denominator. For example... if you were trying to compare 3/4 and 2/8, you would find the common denominator (in this case 8) and convert the fractions...

3/4 = 6/8
2/8 stays as 2/8

Now you would go to the number line between 0 and 1 and divide it into 8 equal pieces. 3/4 would go over the 6th division and 2/8 would go over the second division.

That would give you a good visual that 2/8 < 3/4
