The solution of the equation 4x - 3  = 5 is not extraneous .

Extraneous solutions are values that we get when solving equations that aren't really solutions to the equation.

Therefore, let's solve the equation to know whether it is extraneous solution.

Hence,

4x - 3  = 5

add 3 to both sides of the equation

4x - 3 + 3 = 5 + 3

4x = 8

divide both sides of the equation by 4

4x / 4 = 8 / 4

x = 2

Therefore, it is not extraneous solution.

Answer:

A

Step-by-step explanation:

Length : \(\frac{7x}{2} + 7y\)

Perimeter: \(15x + 17y\)

Perimeter = 2(Length + Width)

15x + 17y = 2( \(\frac{7x}{2} + 7y\) + Width)

15x + 17y = 7x + 14y + 2(Width)

15x + 17y -7x -14y = 2(Width)

8x + 3y = 2(Width)

Width = \(\frac{8x + 3y}{2}\)

Width = 4x + 3y/2

Answer: The width of the rectangular window is 53 cm.

Step-by-step explanation:

We know that the area of a rectangle is given by the formula:

Area = Length x Width

Substituting the given values, we have:

3816 cm² = 72 cm x Width

To solve for the width, we can divide both sides by 72 cm:

Width = 3816 cm² ÷ 72 cm

Width = 53 cm

Therefore, the width of the rectangular window is 53 cm.

The remaining Kit volume in the syringe is sufficient to correct the dose to 20 mCi.

To solve this problem, we can use the concept of radioactive decay and the decay factor. Here's how we can calculate the required volume to correct the dose:

Determine the initial activity of the kit:

Initial activity = 180 mCi

Calculate the decayed activity at 9:30 (after 1.5 hours):

Decay factor = 0.841

Decay activity = Initial activity * Decay factor

Calculate the remaining activity after withdrawing 20 mCi at 8 am:

Remaining activity = Initial activity - 20 mCi

Calculate the remaining activity at 9:30:

Remaining activity at 9:30 = Remaining activity * Decay factor

Calculate the desired activity at 9:30 (20 mCi):

Desired activity at 9:30 = 20 mCi

Calculate the volume needed to achieve the desired activity:

Volume needed = Desired activity at 9:30 / Remaining activity at 9:30 * Volume at 9:30

Calculate the remaining volume at 9:30:

Remaining volume = Volume at 8 am - Volume withdrawn - Volume accidentally discharged

Calculate the volume that needs to be added:

Volume to be added = Volume needed - Remaining volume

Let's perform the calculations step by step:

Determine the initial activity of the kit:

Initial activity = 180 mCi

Calculate the decayed activity at 9:30 (after 1.5 hours):

Decay factor = 0.841

Decay activity = 180 mCi * 0.841 = 151.38 mCi

Calculate the remaining activity after withdrawing 20 mCi at 8 am:

Remaining activity = 180 mCi - 20 mCi = 160 mCi

Calculate the remaining activity at 9:30:

Remaining activity at 9:30 = 160 mCi * 0.841 = 134.56 mCi

Calculate the desired activity at 9:30 (20 mCi):

Desired activity at 9:30 = 20 mCi

Calculate the volume needed to achieve the desired activity:

Volume needed = (Desired activity at 9:30 / Remaining activity at 9:30) * Volume at 9:30

Volume at 9:30 = Remaining volume = 30 ml - (30 ml / 2) = 15 ml

Volume needed = (20 mCi / 134.56 mCi) * 15 ml = 2.236 ml

Calculate the remaining volume at 9:30:

Remaining volume = 30 ml - (30 ml / 2) = 15 ml

Calculate the volume that needs to be added:

Volume to be added = Volume needed - Remaining volume = 2.236 ml - 15 ml = -12.764 ml

Since the calculated volume to be added is negative, it means that no additional volume is required. The remaining Kit volume in the syringe is sufficient to correct the dose to 20 mCi.

Answer:

Question 32

Question 33

Step-by-step explanation:

Scale Factor: A number used as a multiplier when scaling an object.

Perimeter: The total distance around the outside of a 2D shape.

Area: The space occupied by a flat shape, measured in two dimensions.

Scale Factor

To find the scale factor from the shaded figure to the unshaded figure, divide the given side length of the unshaded figure by the given side length of the shaded figure:

\(\implies \sf \dfrac{unshaded}{shaded}=\dfrac{9}{24}=\dfrac{3}{8}\)

Ratio of Perimeters

Perimeters are measured in one dimension (length).  To find the ratio of the perimeters, divide the given side length of one figure by the given side length of the other:

\(\sf \implies\dfrac{shaded}{unshaded}=\dfrac{24}{9}=\dfrac{8}{3}\)

Therefore:

\(\sf \implies shaded:unshaded=8:3\)

Ratio of Areas

Area is measured in two dimensions. To find the ratio of the areas, divide the square of the given side length of one figure by the square of the given side length of the other:

\(\sf \implies\dfrac{shaded}{unshaded}=\dfrac{24^2}{9^2}=\dfrac{64}{9}\)

Therefore:

\(\sf \implies shaded:unshaded=64:9\)

Area of the smaller figure (unshaded)

Area of shaded figure = 1024 mm²

Let x = area of unshaded figure

Use the ratio found above:

\(\begin{aligned}\implies \sf \dfrac{shaded\:area}{unshaded\:area} & =\sf \dfrac{64}{9}\\\\\sf \dfrac{1024}{x} & =\sf \dfrac{64}{9}\\\\\sf 1024 \cdot 9 & = \sf 64x\\\\\sf x & = \sf \dfrac{1024 \cdot 9}{64}\\\\\implies \sf x & = \sf 144\:\:mm^2\end{aligned}\)

Scale Factor

To find the scale factor from the shaded figure to the unshaded figure, divide the given side length of the unshaded figure by the given side length of the shaded figure:

\(\implies \sf \dfrac{ushaded}{shaded}=\dfrac{20}{14}=\dfrac{10}{7}\)

Ratio of Perimeters

Perimeters are measured in one dimension (length).  To find the ratio of the perimeters, divide the given side length of one figure by the given side length of the other:

\(\sf \implies\dfrac{shaded}{unshaded}=\dfrac{14}{20}=\dfrac{7}{10}\)

Therefore:

\(\sf \implies shaded:unshaded=7:10\)

Ratio of Areas

Area is measured in two dimensions. To find the ratio of the areas, divide the square of the given side length of one figure by the square of the given side length of the other:

\(\sf \implies\dfrac{shaded}{unshaded}=\dfrac{14^2}{20^2}=\dfrac{49}{100}\)

Therefore:

\(\sf \implies shaded:unshaded=49:100\)

Area of the smaller figure (shaded)

Area of unshaded figure = 400 in²

Let x = area of shaded figure

Use the ratio found above:

\(\begin{aligned}\implies \sf \dfrac{shaded\:area}{unshaded\:area} & =\sf \dfrac{49}{100}\\\\\sf \dfrac{x}{400} & =\sf \dfrac{49}{100}\\\\\sf x& = \sf \dfrac{400 \cdot 49}{100}\\\\\implies \sf x & = \sf 196\:\:in^2\end{aligned}\)

Answer:

Step-by-step explanation:

The answer is 54.5 on edg

For the triangle shown on the right, the term cos is used to complete the statement and the value of x is 54.5 degree for the triangle.

In a right angle triangle ratio of adjacent side to the hypotenuse side is equal the cosine angle between them.

\(\rm \cos=\dfrac{ adjacent}{hypotenuse}\)

Here, (a) is the adjacent side, (c) is the hypotenuse side and θ is the angle made between them.

The traingle is not provided in the image. Let the triangle for the given problem is similar to the attached image below.

Here the hypontenuse side is AC and adjacent side of triangle is 14.1 units. Thus by the property of right angle triangle,

\(\cos75=\dfrac{AB}{AC}\\\cos75=\dfrac{14.1}{x}\)

Now if we compare the above equation with the given statement __(75*)=14.1/x. The term cos is filled in the blank.

For the second part, we need to find the value of x. Thus solve the above equation further as,

\(\cos75=\dfrac{14.1}{x}\\x=\dfrac{14.1}{\cos75}\\x=\dfrac{14.1}{0.25882}\\x\approx54.5^o\)

Hence, For the triangle shown on the right, the term cos is used to complete the statement and the value of x is 54.5 degree for the triangle.

Answer:

Each widget should be sold for $22.2.

Step-by-step explanation:

Vertex of a quadratic function:

Suppose we have a quadratic function in the following format:

\(f(x) = ax^{2} + bx + c\)

It's vertex is the point \((x_{v}, f(x_{v})\)

In which

\(x_{v} = -\frac{b}{2a}\)

If a<0, the vertex is a maximum point, that is, the maximum value happens at \(x_{v}\), and it's value is \(f(x_{v})\)

In this question:

The profit, y, is a quadratic function related to the price of widgets, x.

We want to find the price of each widget to generate maximum profit, that is, the x value of the vertex.

The profit function is:

\(y = -5x^2 + 222x - 1510\)

So \(a = -5, b = 222, c = -1510\)

The price for maximum profit is given by:

\(x_{v} = -\frac{b}{2a} = -\frac{222}{2(-5)} = -\frac{222}{-10} = 22.2\)

Each widget should be sold for $22.2.

Numbers 1 and 2 are correct.

Question 3:

We can see in each figure, the number of rows matches the figure amount. For example, figure 1 has 1 row, figure 2 has 2 rows, figure 3 has 3 rows, etc. Another thing we can see is that one block gets added to each column in every figure. If we count starting from 3 and keep adding 1 for each column, we get 22 blocks for one column. In figure 20, there will be 20 rows and 22 columns. We also have to keep in mind that they add 2 extra blocks at the top and bottom that stick out like the ones shown. In total, figure 20 will consist of 442 blocks.

Question 4:

[(2 + f) * (f)] + 2 = b

(2 + f) represents the number of blocks in each column.

(f) represents the number of blocks in each row.

2 represents the two extra blocks in each figure.

Note that f in this equation equals the number of the figure. For example, figure 3 is f = 3

We can test our equation with figure three.

[(2 + f) * (f)] + 2 = b

We have figure three so f = 3. Substitute and solve.

[(2 + 3) * (3)] + 2 = b

[5 * 3] + 2 = b

15 + 2 = b

17 = b

In the example, the number of blocks is 17. Therefore, this equation works for any figure.

Best of Luck!

Answer:

Figure 20 will have a limit of 442 blocks.

Step-by-step explanation:

The definite integral of sin^5(x)dx from 0 to pi/2 can be evaluated using the method of substitution.

Let u = sin(x), then du = cos(x)dx

The integral becomes:

∫sin^5(x)dx = ∫u^5du from 0 to sin(π/2)

= (u^6)/6 evaluated at sin(π/2) and 0

= (sin^6(π/2))/6 - 0

= (1^6)/6

= 1/6

So, the definite integral of sin^5(x)dx from 0 to pi/2 is equal to 1/6.
