Answer: 32.036 now round this! Good Luck :)

Step-by-step explanation:

Answer:

1. Reflection

2. rotation and reflection

3. b', b''

4. 26.3

Step-by-step explanation:

1. It is like looking in a mirror. Its is being reflected across the y axis

2. It is rotated 90 degrees to the right. Then reflected over the x axis.

3. they are the same

4. It is the same as A" B" C" D" so the lengths are the same and you just add them.

Answer:

           h ≤ -12/5

Step-by-step explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "8.4" was replaced by "(84/10)".

Rearrange:

Rearrange the equation by subtracting what is to the right of the less equal sign from both sides of the inequality :

                    h-6-(-(84/10))≤0

Step by step solution :

Rewriting the whole as an Equivalent Fraction

2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  5  as the denominator :

             h - 6     (h - 6) • 5

    h - 6 =  —————  =  ———————————

               1            5    

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

(h-6) • 5 - (-42)     5h + 12

—————————————————  =  ———————

        5                5  

Equation at the end of step

2

:

 5h + 12

 ———————  ≤ 0

    5  

STEP

3

:

3.1    Multiply both sides by  5

3.2    Divide both sides by  5  

     h+(12/5)  ≤ 0

Solve Basic Inequality :

3.3      Subtract  12/5  from both sides

           h ≤ -12/5

Inequality Plot :

3.4      Inequality plot for

        h  + 2.400  ≤  0

The value of h is less than or equal to -2.4.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Given:

h−6 ≤−8.4

Now, add both side 6

h−6 + 6 ≤−8.4 + 6

h  ≤−2.4

Hence, the value of h is less than or equal to -2.4

Answer:

  A. (-√2, 3+(4√2)/3), (√2, 3-(4√2)/3)

Step-by-step explanation:

The tangents are horizontal where the derivative is zero. The derivative of the given function is ...

  y' = x² -2

This is zero when ...

  0 = x² -2

  2 = x²

  ±√2 = x . . . . x-values where the derivative is zero

__

The corresponding y-values are ...

  y = (1/3x² -2)x +3

  y = (1/3(2) -2)(±√2) +3 = 3 ∓ (4√2)/3

The turning points are (-√2, 3+(4√2)/3) and (√2, 3-(4√2)/3).

See attachment for number line

Step-by-step explanation:

Given

[tex]Ian = \frac{6}{8}[/tex]

[tex]Anna = \frac{3}{4}[/tex]

Required

Number line to represent both amounts

The interval on the number line is 16.

So, we need to calculate the position of both as thus.

[tex]Ian = \frac{6}{8} * 16 = \frac{96}{8} = 12[/tex]

[tex]Anna = \frac{3}{4} * 16 = \frac{48}{4} = 12[/tex]

So, both will be positioned on the 12th position.

The yellow dot represents Anna while the blue dot represents Ian

Step-by-step explanation:

y^6/y^2= y^4

Answer:

Step-by-step explanation:

This is because,

As,

[tex] {a}^{x} \div {a}^{y} = {a}^{x - y} [/tex]

Here ,

[tex] {y}^{6} \div {y}^{2} [/tex]

[tex] = {y}^{6 - 2} [/tex]

[tex] = {y}^{4} [/tex]

And here the result does not simplify to,

Hence, Last Option is the correct answer

Answer:

Factoring

Step-by-step explanation:

When we are solving a quadratic equation by the factorization method, each factor is set as being equal to zero.

The solution of each bracket of factors gives the root of the quadratic equation.

For example;

x2 + 16 = 10x

We now have;

x2 - 10x + 16  = 0

x2 - 8x - 2x + 16 = 0

x(x - 8) -2(x - 8) = 0

(x-2) (x-8) = 0

(x-2) = 0

Then x = 2

Or

(x-8) = 0

x = 8

Hence;

x = 2 or x= 8

Answer:

  (d)  D: [0, 60]; R: [-15, 0]

Step-by-step explanation:

The model is of the underwater portion of the net, so the only part of the graph we're interested in is that below the x-axis.

The x-intercepts of 0 and 60 define the bounds of the domain.

The range is the vertical extent of the graph in that domain, from y=-15 to y=0.

So, the domain and range are ...

  Domain: 0 ≤ x ≤ 60

  Range: -15 ≤ y ≤ 0
