Answer:

[tex]Z = \frac{37i }{113 } - \frac{23}{113} [/tex]

Step-by-step explanation:

We have the complex number relationship as:

E=IZ

Where E=(5+9i) and I=(8+7i)

We solve for Z to get;

Z=E/L

We then substitute the expressions to get:

[tex]Z = \frac{5 + 9i}{8 + 7i} [/tex]

We rationalize to get:

[tex]Z = \frac{5 + 9i}{8 + 7i} \times \frac{8 - 7i}{8 - 7i} [/tex]

We simplify to obtain:

[tex]Z = \frac{40 - 35i + 72i - 63}{ {8}^{2} + {7}^{2} } [/tex]

This gives

[tex]Z = \frac{37i - 23}{113 } [/tex]

Or

[tex]Z = \frac{37i }{113 } - \frac{23}{113} [/tex]

Step-by-step explanation:

Answer:

7.1ft

Step-by-step explanation:

The formula for calculating the total surface area of a cube is 2(L²+L²+L²)

=2(3L²)

= 6L²

Where L is the length of the cube

If the total surface area of a cube is 302.46ft², then

302.46 = 6L²

L² = 302.46/6

L² = 50.41

L =√50.41

L = 7.1ft

The length of the side of the cube is 7.1ft

The length of the side of the cube is approximately [tex]\( 7.1 \, \text{ft} \).[/tex]

To find the length of the side of a cube given its total surface area, we need to use the formula for the surface area of a cube.

The formula for the surface area of a cube is:

[tex]\[ \text{Surface Area} = 6s^2 \][/tex]

where s is the length of a side of the cube.

Given the total surface area is [tex]\( 302.46 \, \text{ft}^2 \)[/tex], we can set up the equation:

[tex]\[ 6s^2 = 302.46 \][/tex]

To solve for s we first divide both sides by 6:

[tex]\[ s^2 = \frac{302.46}{6} \][/tex]

[tex]\[ s^2 = 50.41 \][/tex]

Next, we take the square root of both sides to find s

[tex]\[ s = \sqrt{50.41} \][/tex]

[tex]\[ s \approx 7.1 \, \text{ft} \][/tex]

Thus, the length of the side of the cube is approximately [tex]\( 7.1 \, \text{ft} \).[/tex]

Answer:

£518

Step-by-step explanation:

Asking price = original cost × markup%

A = 280(1.85) = 518

Brian May needs to price his Antique Cherry Special guitar at £518. This price is determined by the original cost, £280, and a 85% markup, £238, on this cost.

Brian May needs to define a price for his signature Antique Cherry Special guitar that was costed at £280 and he wants an 85% markup on this cost. Markup is calculated by multiplying the cost by the markup percentage. In this case, the markup is £280 * 85/100 = £238. Therefore, to determine the final price Brian needs to add the original cost and the markup, which is £280 + £238 = £518. So the price Brian should ask for the guitar is £518.

D.) A 90 degree clockwise rotation about the origin

Step-by-step explanation:

The red triangle should have a 90° clockwise rotation about the origin. Option C is correct.

Given that,
A graph of figures is shown in the pictures,
Which transformation of the red triangle on the graph maps it onto the missing piece of the square is to be determined.

The translation is defined as the change of position through linear distance and angle.

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

In order to occupy the required space on the green figure by red triangle, it should be rotated to 90° clockwise about the origin.

Thus, the red triangle should have a 90° clockwise rotation about the origin. Option C is correct.

Answer:

The height of the flagpole is 25 foot.

Step-by-step explanation:

Given:

Height of the stick = 5 foot

Shadow of the stick = 4 foot

Another one:

Height of the flagpole = 'x'

Shadow of the flagpole = 20 foot

Note:The shadows are formed at the same time of the day so the Sun makes an equal angle with both the situation.

Here from both ends it forms two similar triangles.

So,

We can say that:

⇒ [tex]\frac{Height\ of\ the\ flagpole}{Shadow\ of\ the\ flagpole}=\frac{Height\ of\ the\ stick}{Shadow\ of\ the\ stick}[/tex]

⇒ [tex]\frac{x}{20}=\frac{5}{4}[/tex]

⇒ [tex]\frac{x}{20}\times 20=\frac{5}{4}\times 20[/tex]

⇒ [tex]x=25[/tex] foot

So Darius estimated height of the flagpole = 25 foot.

Answer:

[tex]68 \: {cm}^{2} [/tex]

Step-by-step explanation:

You can use 1 cm = 10 mm very well to help you with this.

The small two at the end of the unit (cm^2) refers, that the shape of an object is two dimensional. If we make 1 cm two dimensional by multiplying it with the original 1 cm, we get a total area of

[tex]1 \: {cm} \times 1 \: {cm} \: = 1 \: {cm}^{2} [/tex]

We have created an equation. Since we know 1 cm = 10 mm, we can replace the centimetres in the equation with the millimetres, like so:

[tex]10 \: mm \times 10 \: mm = 1 \: {cm}^{2} \\ 100 \: {mm}^{2} = 1 \: {cm}^{2} [/tex]

From there, its just a simple matter of calculation:

You can determine if a polygon is a convex, by which way the edges points out

Convex is when all the points are facing out, so a polygon is a convex if all the edges are pointing out.

Answer:

  No side of the polygon crosses any other, even when extended indefinitely.

Step-by-step explanation:

If no sides of the polygon cross each other, it is convex when it has no internal reflex angles (angles measuring more than 180°). If sides of the polygon cross each other, it is not convex.

Another way to describe a convex polygon is that extending any one side indefinitely will not cause it to cross any other side.

Answer:

The answer is A)$10.50

Step-by-step explanation:

In order to solve the average amount, you have to add the total amount of money spent and divide it by the total number of times you spent money on food. The total sum of money spent was $63. If you divide that by how many times you ate (6 times) you'll get the dividend/answer of 10.5.

Hope this helps :)

You are spending, on average, A) $10.50 per day on food.

The correct answer is A) $10.50.

To find the average amount spent per day on food, you need to add up the total amount spent over the 6 days and then divide it by the number of days (6).

Total amount spent on food = $8 + $14 + $12 + $11 + $5 + $13

                                               = $63

Average amount spent per day = Total amount spent / Number of days

                                                     = $63 / 6

                                                     = $10.50

So, you are spending, on average, $10.50 per day on food.

Step-by-step explanation:

18 = 4x + 2

solve for x

subtract 2 from each side

16 = 4x

divided by 4

16/4 = 4

Answer: 4 apples

Step-by-step explanation:

To solve the equation, you need to isolate/get "y" by itself in the equation:

3y - 4 = 6 - 2y        Add 2y on both sides

3y + 2y - 4 = 6 - 2y + 2y

5y - 4 = 6        Add 4 on both sides

5y - 4 + 4 = 6 + 4

5y = 10          Divide 5 on both sides

[tex]\frac{5y}{5} =\frac{10}{5}[/tex]

y = 2

PROOF

3y - 4 = 6 - 2y        Substitute/plug in 2 for y

3(2) - 4 = 6 - 2(2)

6 - 4 = 6 - 4

2 = 2

After Solving the equation for 3y-4=6-2y, we get y = 2. We must isolate the variable y on one side of the equation in order to get the solution to the equation 3y - 4 = 6 - 2y. Here's a step-by-step procedure:

Start by solving 3y - 4 = 6 - 2y, which is the provided problem.

Add 2y to both sides of similar phrases to combine them: 3y + 2y - 4 = 6 - 2y + 2y.

Simply put, this is: 5y - 4 = 6.

Add 4 to both sides of the variable word to isolate it: 5y - 4 + 4 = 6 + 4.

This may be summarised as 5y = 10.

To find y, multiply both sides of the equation by 5. (5y) / 5 = 10 / 5.

This may be condensed to: y = 2.

Consequently, y = 2 is the answer to the equation 3y - 4 = 6 - 2y.
