Answer:

  y was not substituted for every x

Step-by-step explanation:

To find the inverse of ...

  y = f(x)

you need to solve ...

  x = f(y)

Here, f(x) = x^2 +12x, so f(y) = y^2 +12y

This is not the expression we see on the right of ...

  x = y^2 +12x

Apparently y was not properly substituted into f(x).

Area of the larger square: (4 cm) * (4 cm) = 16 cm^2

Area of the smaller square: (2 cm) * (2 cm) = 4 cm^2

Area of the shaded region = difference between the two areas above, or 12 cm^2

Answer:

Answer:

89.132 inch

Step-by-step explanation:

“this shape is made up of one half-circle attached to a square with side lengths 16 inches. You can use 3.14 as an approximation.”

so, the square has a perimeter of 16 inch, four sides that will be 64 inch

then the half circle rule of perimeter of half circle: πr + 2r

=> perimeter of semicircle = π * 8 +2 * 8 = 41.132 inch

without the bottom line of half circle= 41.132 -16 = 25.133 inch

So total 25.133 + 64 =89.132 inch

Answer:

w= 23/12

Step-by-step explanation:

1. Multiply the numbers.

23=9w-1*8/3+5w-1*7/6

23=9w-8/3+5w-1*7/6

2. Subtract the numbers.

23=9w-8/3+5w-7/6

23=9w-23/6+5w

3. Combine Like terms

23=9w-23/6+5w

23=14w-23/6

4. Add 23/6 to both sides of the equation.

23+23/6=14w-23/6=26/6

5. Simplify

161/6=14w

6. Divide both sides of the equation by the same term.

161/6=14w

161/6/14=14w/14

7. Simplify

w=23/12

Answer:

x = 5

Step-by-step explanation:

We know that BD = 2x - 1 and BC + CD = BD.  Thus, we can set the sum of (x- 3) and 7 equal to 2x - 1 to find x:

BC + CD = BD

x - 3 + 7 = 2x - 1

x + 4 = 2x - 1

x + 5 = 2x

5 = x

Thus, x = 5

Checking the validity of our answer:

We can check that our answer is correct by plugging in 5 for x in x - 3 and 2x - 1 and checking that we get the same answer on both sides of the equation:

5 - 3 + 7 = 2(5) - 1

2 + 7 = 10 - 1

9 = 9

The total cost to run Val’s AC costs for a summer month of 30 days will be $67.5.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Quantity of electricity used in kilowatts is;

1000 watts = 1 kilowatts

2,500 watts = 2.5 kilowatts

Given that Number of hours Val runs AC per day = 5 hours

Number of days = 30 days

Cost of electricity = $0.18 kilowatts per hour

The Cost of Val’s AC to run for a summer month of 30 days can be calculated as;

= Quantity of electricity used × Number of hours Val runs AC per day × Number of days × Cost of electricity

= 2.5 × 5 × 30 × 0.18

= $67.5

The total cost to run Val’s AC costs for a summer month of 30 days will be $67.5.

B; There is only one (x,y) solution and y is negative

Step-by-step explanation:

First, I graphed the two equations. Attached is an image of the equations graphed. Next, I looked for overlapping points. Wherever the two points overlap, there is a solution. When looking at the graph, we can see the lines overlap at only one point, (0,-1). Since y is negative, the answer must be B; there is only one (x,y) solution and y is negative.

<EDF = 15°

<EDB = 15° + 20° = 35°

This is <EDF + <EDB as each is 15° and 20° respectively.

Answer:

(-4, -4).

Step-by-step explanation:

In order to calculate the midpoint coordinates, we need to calculate the mean value of the x-coordinates and the mean value of the y-coordinates.

So we have:

M(x)=(-1+(-7))/(2)=(-8)/(2)=-4

M(y)=(-6+(-2))/(2)=(-8)/(2)=-4

Therefore the midpoint coordinates are (-4, -4).

Answer:

35.09 units

Step-by-step explanation:

This is a right-angled triangle where:

Hypotenuse = x units

With respect to angle 20°:

Opposite = 12 units

Use trigonometric function sinФ to solve for x:

sinФ = \(\frac{Opposite}{Hypotenuse}\)

∴sin20° = \(\frac{12}{x}\)

Cross-multiplication is applied:

\((x)(sin20) = 12\)

x has to be isolated and made the subject of the equation:

∴\(x = \frac{12}{sin20}\)

x = 35.09 units (Rounded to 2 decimal places)

Answer:

The length of x is 35.09 units to two decimal places.

Step-by-step explanation:

In the given right triangle, we have been given the length of the side opposite the angle and need to find the length of the hypotenuse.

To find the value of x, use the sine trigonometric ratio.

\(\boxed{\begin{minipage}{9 cm}\underline{Sine trigonometric ratio} \\\\$\sf \sin(\theta)=\dfrac{O}{H}$\\\\where:\\ \phantom{ww}$\bullet$ $\theta$ is the angle. \\ \phantom{ww}$\bullet$ $\sf O$ is the side opposite the angle. \\\phantom{ww}$\bullet$ $\sf H$ is the hypotenuse (the side opposite the right angle). \\\end{minipage}}\)

Substitute θ = 20°, O = 12 and H = x into the ratio and solve for x:

\(\implies \sin 20^{\circ}=\dfrac{12}{x}\)

\(\implies x=\dfrac{12}{\sin 20^{\circ}}\)

\(\implies x=35.085652...\)

\(\implies x=35.09\; \sf (2\;d.p.)\)

Therefore, the length of x is 35.09 units to two decimal places.

Answer:

\(P(White\ and\ Purple) = 2.52\%\)

Step-by-step explanation:

Given

\(Purple = 18\)       \(Green = 34\)         \(White = 14\)

\(Blue = 26\)          \(Black = 8\)

Required

Probability of first selecting white and then selecting purple

The total boxes is:

\(Total = 18+34+14+26+8\)

\(Total = 100\)

The probability is represented as:

\(P(White\ and\ Purple)\)

And the solution is:

\(P(White\ and\ Purple) = P(White) * P(Purple)\)

\(P(White\ and\ Purple) = \frac{n(White)}{Total} * \frac{n(Purple)}{Total}\)

\(P(White\ and\ Purple) = \frac{14}{100} * \frac{18}{100}\)

\(P(White\ and\ Purple) = \frac{14*18}{100*100}\)

\(P(White\ and\ Purple) = \frac{252}{10000}\)

\(P(White\ and\ Purple) = 0.0252\)

or

\(P(White\ and\ Purple) = 2.52\%\)
