Hey there!

2(12)3/2

= 2(12)(3/2)

= 24(3/2)

= 24/1 * 3/2

= 24(3) / 1(2)

= 24 + 24 + 24 / 1 + 1

= 48 + 24 / 2

= 72 / 2

= 72 ÷ 2 / 2 ÷ 2

= 36 / 1


= 36 ÷ 1


= 36

Therefore, your answer is: 36

Good luck on your assignment & enjoy your day!

Rhea draws rows and columns on a big piece of paper to make 16 same-sized squares. How many rows and columns does she draw? I

Answers

Answer:

4 rows and 4 columns

Step-by-step explanation:

Given

16 same sized squares

Required

Determine the number of rows and columns

Since the shape formed is a square, then the following relationships exist:

[tex]Row * Column = 16[/tex]

[tex]Row = Column[/tex]

[tex]Row * Column = 16[/tex] can then be rewritten as:

[tex]Row * Row = 16[/tex]

[tex]Row^2 = 16[/tex]

Take square roots of both sides

[tex]Row = \sqrt{16[/tex]

[tex]Row = 4[/tex]

[tex]Row = Column[/tex] implies that:

[tex]Row = Column = 4[/tex]

 2x • (2x2 + 1) • (5x - 3)

Step-by-step explanation:

5.4    Find roots (zeroes) of :       F(x) = 2x2 + 1

Polynomial Roots Calculator is a set of methods aimed at finding values of  x  for which   F(x)=0  

Rational Roots Test is one of the above mentioned tools. It would only find Rational Roots that is numbers  x  which can be expressed as the quotient of two integers

The Rational Root Theorem states that if a polynomial zeroes for a rational number  P/Q   then  P  is a factor of the Trailing Constant and  Q  is a factor of the Leading Coefficient

In this case, the Leading Coefficient is  2  and the Trailing Constant is  1.

The factor(s) are:

of the Leading Coefficient :  1,2

of the Trailing Constant :  1

Final result :

 2x • (2x2 + 1) • (5x - 3)

If the buses run on schedule, when is the next time a red line and a blue line bus will leave together? Show your work.

Answers

Answer:

So the next time they will leave together is 4:24 pm

Step-by-step explanation:

Since both the buses left at 4 pm and red line bus leaves every 6minutes and blue line bus leaves every 8 minutes they next time they leave together can be found by taking the L.C. M of 6 and 8.

The L.C. M is found by multiplying all the factors and chosing one which common in both numbers.

Factors of 6 = 2*3

Factors of 8= 2*2*2

In these numbers 2 is common in both.The rest of the numbers( 2*2*3 )are multiplied with the the common 2 to get the L.C.M

L.C.M= 2*2*2*3= 24 minutes

So the next time they will leave together is 4:24 pm

Answers

Answer:

y=(-7/2)x+3

Step-by-step explanation:

7x+2y-3=0

7x+2y=3

2y=-7x+3

y=(-7/2)x+3

Answer:

y = - [tex]\frac{7}{2}[/tex] x + [tex]\frac{3}{2}[/tex]

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

7x + 2y - 3 = 0 ( subtract 7x - 3 from both sides )

2y = - 7x + 3 ( divide each term by 2 )

y = - [tex]\frac{7}{2}[/tex] x + [tex]\frac{3}{2}[/tex] ← in slope- intercept form
