Create An Equivalent Expression For ( 1.4 / 1.2)1.4/1.21.2/1.41.4/1.21.2/1.4

Answers

Answer 1

The correct answer is:  [D]:  " [tex]\frac{(1.2)^2^4}{(1.4)^1^8}[/tex]  "

Step-by-step explanation:

Given:  ( 1.4³ / 1.2⁴)⁻⁶ ;

Note the following properties of exponents:

1)    [tex]a^-^b = \frac{1}{a^b}[/tex] ;  { [tex]a\neq 0[/tex] } ;  and:

2)   the  'power of a fraction' rule:
 [tex](\frac{a}{b})^c} =\frac{a^c}{b^c}[/tex] ;  [tex]b\neq 0[/tex] '

As such:
[tex](\frac{1.4^3}{1.2^4})^{-6}[/tex]  ;

=  1  ÷ ( [tex]\frac{1.4^3}{1.2^4})^{6}[/tex] ;

=  [tex]\frac{1}{1}[/tex]   ÷ ( [tex]\frac{1.4^3}{1.2^4})^{6}[/tex] ;;

=  [tex]\frac{1}{1}[/tex]   ÷   [tex]\frac{1.4^(^3^*^6^)}{1.2^(^4^*^6^)}[/tex] ;

Note the follow property of exponents:
" [tex](\frac{a}{b})^c = \frac{a^c}{b^c}[/tex] " ;  {" b ≠ 0 "}.

⇒ =   [tex]\frac{1}{1}[/tex]   ÷ [tex]\frac{1.4^(^1^8^)}{1.2^(^2^4^)}[/tex]

Note:  Dividing by a fraction or a number; is the same as multiplying by the reciprocal (invert) of that number.

   =   [tex]\frac{1}{1}[/tex]   *  [tex]\frac{1.2^(^2^4^)}{{1.4^(^1^8^)}}[/tex] ;

   =     "  [tex]\frac{1.2^(^2^4^)}{{1.4^(^1^8^)}}[/tex]  "  ;

which corresponds to:
Answer choice:  [D]:   " [tex]\frac{1.2^(^2^4^)}{{1.4^(^1^8^)}}[/tex] " .

The graph of the inequality is attached below.

What is inequality?

In mathematics, inequalities describe the relationship between two values that are not equal. Equal means to be equal, not. The "not equal symbol (≠)" is typically used to indicate that two values are not equal. But different inequalities are used to compare the values to determine whether they are less than or greater than.

Consider, the given inequality

      K/2 - 20 ≥ -18

Add 20 on both sides,

K/2 - 20 + 20 ≥ -18 + 20

               K/2 ≥ 2

Multiply both sides by 2,

        K/2 x 2 ≥ 2 x 2

                  K ≥ 4

Alex came home after school one day and found that his mother had left a plate of cookies. Alex ate 1/4 of the cookies. When his sister Bernice came home, she ate 1/3 of the remaining cookies, and when Carla came home, she ate 1/2 of the cookies on the plate. When their mother came home, there were 5 cookies on the plate. How many did each child eat?

Answers

Answer: Children ate 15 cookies and 5 each because Alex ate 1/4 and bernice ate 1/3 and carla ate 1/2
and 5 were left

5 into 3 is 20
and 5 are left so
20-5 is 15
15 divide by 3 is 5

The congruent reason for 5 is (c) ASA

How to determine the congruent reason for 5?

From the question, we have the following parameters that can be used in our computation:

Triangles = VWX and ZYX

The ASA similarity theorem implies that the corresponding angles of the triangles in question are similar and the sides between these angles are congruent

From the question, we can see that the following corresponding angles on the triangles:

Angles W and Y

Angles X and X

This implies that these angles are congruent angles

For the triangle to be congruent by ASA, the following sides must also be congruent

WX must be congruent to YX

This is indicated in the table of values at (3)

integral 2x+11/x^2-x-2 dx

Answers

The Integral value of  (2x+11)/(x²-x-2) is[tex]2(\frac{1}{3} log|x+1|+\frac{2}{3} log|x-2|)-\frac{11}{3} (log|\frac{2}{3} x+\frac{2}{3}|-log|\frac{2}{3} x-\frac{4}{3}|)+c[/tex]

What is Integration?

An integral assigns numbers to functions in a way that describes displacement, area, volume, and other concepts that arise by combining infinitesimal data.

The given integral is [tex]\int\dx \frac{2x+11}{x^{2} -x-2} dx[/tex]

By partial fractions we divide the integral

Apply the sum rule:

∫f(x)±g(x)dx=∫f(x)dx±∫g(x)dx

[tex]=\int\dx \frac{2x}{x^{2} -x-2} dx+\int\dx \frac{11}{x^{2} -x-2} dx[/tex]

Let  us calculate the first integral part

[tex]=\int\dx \frac{2x}{x^{2} -x-2} dx[/tex]

Let us use the partial fraction of [tex]\frac{x}{x^{2} -x-2} dx:\frac{1}{3(x+1)} +\frac{2}{3(x-2)}[/tex]

[tex]\int\dx \frac{2x}{x^{2} -x-2} dx=2\int\dx \frac{1}{3(x+1)} dx+ \frac{2}{3(x-2)} dx[/tex]

[tex]\int\dx \frac{2x}{x^{2} -x-2} dx=2(\frac{1}{3} log|x+1|+\frac{2}{3} log|x-2|)[/tex]

Now let us integrate second term.

[tex]\int\dx \frac{11}{x^{2} -x-2} dx=11\int\dx \frac{1}{x^{2} -x-2} dx[/tex]

We can write denominator as x²-x-2= (x-1/2)²-9/4

[tex]=11\int\dx \frac{1}{(x-\frac{1}{2}) ^{2} -\frac{9}{4}} dx[/tex]

We apply u substitution method

[tex]\int\dx \frac{11}{x^{2} -x-2} dx=-\frac{11}{3} (log|\frac{2}{3} x+\frac{2}{3}|-log|\frac{2}{3} x-\frac{4}{3}|)[/tex]

[tex]=2(\frac{1}{3} log|x+1|+\frac{2}{3} log|x-2|)-\frac{11}{3} (log|\frac{2}{3} x+\frac{2}{3}|-log|\frac{2}{3} x-\frac{4}{3}|)+c[/tex]

Hence, [tex]2(\frac{1}{3} log|x+1|+\frac{2}{3} log|x-2|)-\frac{11}{3} (log|\frac{2}{3} x+\frac{2}{3}|-log|\frac{2}{3} x-\frac{4}{3}|)+c[/tex] is the integral value of of (2x+11)/(x²-x-2).

Given 2x + 3 is the hypotenuse, use the Pythagorean

Step-by-step explanation:

Given right triangle sides x, 2x-3, and 2x+3, you want to know the length of the side labeled x.

Pythagorean theorem

The Pythagorean theorem tells you the square of the hypotenuse is equal to the sum of the squares of the other two sides.

  (2x +3)² = (2x -3)² +x²

  4x² +12x +9 = 4x² -12x +9 +x²

  x² -24x = 0 . . . . . subtract 4x² +12x +9

  x(x -24) = 0   ⇒   x = 0 or 24

The length of the side labeled x is 24 units.

What are the possible rational zeros of f(x) = x^4+2x^3-3x^2-4x-12

Answers

The solution of the function f(x) = (x - 2)(x + 6)(x² + x + 2) will be 2, -3, - 1/2 + (√7/2)i, and - 1/2 - (√7/2)i.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

The function is given below.

f(x) = (x⁴ + 2x³ - 3x² - 4x - 12)

Factorize the expression, then we have

f(x) = (x⁴ + 2x³ - 3x² - 4x - 12)

f(x) = x⁴ - 2x³ + 4x³ - 8x² + 5x² - 10x + 6x - 12

f(x) = x³(x - 2) + 4x²(x - 2) + 5x(x - 2) + 6(x - 2)

f(x) = (x - 2)(x³ + 4x² + 5x + 6)

f(x) = (x - 2) (x³ + 3x² + x² + 3x + 2x + 6)

f(x) = (x - 2)[x²(x + 3) + x(x + 3) + 2(x + 3)]

f(x) = (x - 2)(x + 6)(x² + x + 2)

The zeroes of the function are given as,

f(x) = 0

(x - 2)(x + 3)(x² + x + 2) = 0

x = 2, -3, - 1/2 + (√7/2)i, - 1/2 - (√7/2)i

The solution of the function f(x) = (x - 2)(x + 6)(x² + x + 2) will be 2, -3, - 1/2 + (√7/2)i, and - 1/2 - (√7/2)i.

How to write the unit form for 1/3

Answers

Answer:

To write the unit form for 1/3, you can simply write "1/3" or use the fraction symbol, which looks like a horizontal line with the numerator above the denominator. For example, you can write the unit form for 1/3 as follows:

1/3

Alternatively, you can use the fraction symbol, like this:

1/3

In both cases, the numerator (the number on top of the fraction) is 1 and the denominator (the number on the bottom of the fraction) is 3. This indicates that the value of the fraction is one-third.

The width of a rectangular table top is 2 1/2 feet shorter than 3 times it’s length. If the perimeter of the table is 43 feet, what is the length, L, of the table

Answers

Answer: length=6 feet

Step-by-step explanation:

For this you need to create one equation from the question and use the equation for perimeter.

equation 1 is     2W+2L=P   where perimeter is 43.

equation 2 is w=3L-2.5

-Now you want to take equation two and plug it into equation 1 for w to find L

It will be  2(3L-2.5)+2L=43 and you want to solve for L

distribute the 2   2(3L-2.5)+2L=43

add up the Ls      6L-5+2L=43

add 5 to each side    8L-5=43

divide each side by    8L=48

Then you get L=6

Now use L=6 to plug into equation two to get W(width)

w=3(6)-2.5=18-2.5=15.5

Now plug in both W and L into equation 1 to make sure you get 43

P=2(15.5)+2(6)=32+12=43 this means that w and l are correct and you get the perimeter given. So length (L) is 6.
