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]

Final answer:

It would have taken Janet about 9.7536 pages to read..

Explanation:

To determine Janet's reading progress, her reading speed is multiplied by the duration she read. With a reading speed of 3.6 pages per minute, if Janet read for 2.71 minutes, the calculation is 3.6 multiplied by 2.71, resulting in 9.7536. Hence, Janet would have read approximately 9.7536 pages. This calculation showcases how the product of reading speed and time provides a quantitative measure of reading accomplishment. It's a straightforward way to estimate the amount of material covered within a specific timeframe, offering insights into reading efficiency and progress.

Therefore, equation of the line that passes through (-1,5) and is parallel to the line

[tex]2y+4x=-8[/tex]  

is

[tex]y=-2x+3[/tex]

Step-by-step explanation:

Given:

[tex]2y+4x=-8[/tex]        .Equation of line

can be written as

[tex]y=-2x-8[/tex]     ...which is in Slope intercept form

To Find:

Equation of line passing through ( -1, 5) and is parallel to the line 2y+4x=-8

Solution:

[tex]y=-2x-8[/tex] ...........Given

Comparing with,  

[tex]y=mx+c[/tex]    ....general form in slope intercept

Where m =slope  

We get

[tex]Slope = m = -2[/tex]

We know that parallel lines have Equal slopes.

Therefore the slope of the required line passing through (-1 , 5) will also have the slope = m = -2.

Now the equation of line in slope point form given by

[tex](y-y_{1})=m(x-x_{1})[/tex]

Substituting the points and so we will get the required equation of the line,

[tex](y-5)=-2(x-(-1))=-2(x+1)\\\\y-5=-2x-2\\y=-2x+3......Equation\ of\ line[/tex]

Therefore, equation of the line that passes through (-1,5) and is parallel to the line

[tex]2y+4x=-8[/tex]  

is

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:

[tex]6800 \: {mm}^{2} \times \frac{1 \: {cm}^{2} }{100 \: {mm}^{2} } = 68 \: \: {cm}^{2} [/tex]

Answer:

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:

Akira needs 45 square inches of  gold foil to cover the chair free including the bottom​

Step-by-step explanation:

Total surface  =  surface area of the base square + area of 4 triangles

Step 1: The surface area of the base square

surface area of the base = surface area of the square =  [tex]s^2[/tex]

where s is the side length

The the surface area of the base  = [tex]3^2[/tex] = 9 square inches

Step 2: The surface area of the side triangles

The area of the triangle = [tex]\frac{1}{2}\times \text{side length} \times \text{slant height}[/tex]

On substituting the values,

The area of the triangle =[tex]\frac{1}{2} \times 3 \times 6[/tex]

The area of the triangle = [tex]\frac{18}{2}[/tex]

The area of the triangle = 9 square inches

Now the area of 4 triangles  =  4 x 9  = 36 square inches

Thus the total surface area  =  9 + 36 = 45 square inches

The amount of gold foil needed to cover a trophy in the shape of a square pyramid can be calculated using the surface area formula for square pyramids, which considers the base area and the slant height.

To calculate the amount of gold foil needed to cover the trophy, we need to find the surface area of the square pyramid trophy. The surface area of a square pyramid is calculated by the formula: Surface Area = base area + 1/2 * Perimeter of base * slant height. If we know the length of the base (which is a square here), the slant height, we can substitute them into this formula to get the surface area. This is the amount of gold foil Akira used to cover her trophy, assuming the gold foil perfectly fits the trophy shape with no overlap.

Step-by-step explanation:

Let us revise some rules of indices:

∵ [tex]4^{3}[/tex] × [tex]4^{-6}[/tex] = [tex]4^{5}[/tex] × [tex]4^{x}[/tex]

∵ All bases are equal

∴ Use the first and third rule above to find x

∵  [tex]4^{3}[/tex] × [tex]4^{-6}[/tex] = [tex]4^{3+-6}[/tex]

∴  [tex]4^{3}[/tex] × [tex]4^{-6}[/tex] = [tex]4^{-3}[/tex] ⇒ L.H.S

∵  [tex]4^{5}[/tex] × [tex]4^{x}[/tex] = [tex]4^{5+x}[/tex] ⇒ R.H.S

Equate L.H.S and R.H.S

∴  [tex]4^{-3}[/tex] =  [tex]4^{5+x}[/tex]

Equate the indices of the two sides

∴ -3 = 5 + x

- Subtract 5 from both sides

∴ -8 = x

Four to the power of three times four to the power of negative six is equal to four to the power of five times four to the power of negative eight.

To solve for the missing exponent, we can use the following properties of exponents:

Multiplying exponents with the same base: When multiplying powers with the same base, we add their exponents.

Negative exponents: A number raised to a negative exponent is equal to its reciprocal raised to the positive exponent.

Applying these properties:

4^3 * 4^-6 = 4^(3 - 6) = 4^-3 (since 4^-6 = 1/4^6)

4^5 * 4^x = 4^(5 + x)

Setting these equal to find x:

4^-3 = 4^(5 + x)

Therefore, x = -3 - 5 = -8.

Kate and Will meet at 1 : 09 pm

Solution:

The distance between Quebec City and New York City is 520 miles.

At the point where Kate and Will meet, they would have traveled 520 miles.

Let "t" represent the time it takes Kate to travel a certain distance before they met.

[tex]Distance = speed \times time[/tex]

If Kate drives at 55 mph, the distance covered would be

[tex]Distance = 55 \times t = 55t[/tex]

If Will drives at 75 miles per hour, then the distance covered will be

[tex]Distance = 75 \times t = 75t[/tex]

Since the total distance covered is 520 miles

Which means,

[tex]55t + 75t = 520\\\\130t = 520\\\\t = \frac{520}{130}\\\\t = 4[/tex]

Given that in question,

If Kate leaves Quebec and will leaves New York at 9:09 a.m

4 hours after 9: 09 am, Kate and Will will meet

9: 09 am + 4 hours = 1: 09 pm

Thus they would meet at 1 : 09 pm

Answer:

The total number of fliers they gave out is 1368.

Step-by-step explanation:

Given:

Volunteers for a political campaign gave out 21/38 of their fliers. They gave out the remaining 612 fliers in another neighborhood.

Now, to find the total number of fliers they gave out.

Let the total number of fliers be [tex]x.[/tex]

Number of fliers they gave out for a political campaign:

[tex]\frac{21}{38}\ of\ x[/tex]

[tex]=\frac{21}{38} \times x[/tex]

[tex]=\frac{21x}{38}[/tex]

Number of fliers remaining they gave out in another neighborhood = 612.

Now, to get the total number of fliers by putting an equation:

[tex]x-\frac{21x}{38} =612[/tex]

[tex]\frac{38x-21x}{38} =612[/tex]

[tex]\frac{17x}{38} =612[/tex]

Multiplying both sides by 38 we get:

[tex]17x=23256[/tex]

Dividing both sides by 17 we get:

[tex]x=1368.[/tex]

Therefore, the total number of fliers they gave out is 1368.

Answer:

Well no cheating not from me

Step-by-step explanation:

If a number is decreased by 79%, we are left with 21%.

so let's devide by 21 to get down to 1%, then multiply by 100 to get to the origininal number:

13 / 21 * 100 = 61.9047619048

To the nearest tenth it's 61.9

Final answer:

To find the original number when decreased by 79% to result in 13, we solve the equation 0.21x = 13, which gives us 61.9047619. Rounding this to the nearest tenth gives us 61.9.

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.
