A segment in the complex plane has a midpoint at −1 + 7i. If one endpoint of the segment is at
3 + 8i, what is the other endpoint?
__+__i

Answers

Answer 1
Consider two pairs of coordinates (x₁, y₁) and (x₂, y₂), the mid-point of these coordinates are [tex]( \frac{x_1+x_2}{2} , \frac{y_1+y_2}{2} ) [/tex]

We have midpoint (-1, 7i) and one pair of coordinate (3, 8i)

The other pair of coordinate would be given by
[tex]( \frac{x_1+3}{2}= -1, \frac{y_1+8}{2} =7)[/tex]

The value of x is (2 × -1) - 3 = -2 - 3 = -5
The value of y is (2 × 7) - 8 = 14 - 8 = 6

The value of x represents the real part
The value of y represents the imaginary part

The other coordinate is (-5, 6i)

Before a sale, an item’s price was $38.00. After the sale discount, the price became $32.30. What was the percent of the sale discount

Answers

Answer:

15%

Step-by-step explanation:

Before a sale, an item’s price was $38.00.

Original price, p = $38.00

After the sale discount, the price became $32.30.

After discount price, q = $32.30

Difference of sale = 38.00 - 32.30

                            = $5.70

% of sale distance [tex]=\dfrac{difference}{original price}\times 100[/tex]

                              [tex]=\dfrac{5.70}{38.00}\times 100[/tex]

                              [tex]=15\%[/tex]

Hence, The sale discount is 15%

Before a sale, an item’s price was $38.00. After the sale discount, the price became $32.30. The percentage of the sale discount is 15%.

What is the percentage?

A percentage is a minimum number or ratio that is measured by a fraction of 100.

Before a sale, an item’s price was $38.00.

Original price, p = $38.00

After the sale discount, the price became $32.30.

After discount price, q = $32.30

Difference of sale = 38.00 - 32.30

                           = $5.70

The percent of the sale discount = difference/ original  x 100

                                                      = 5.70 / 38.00  x 100

                                                      = 15%

Thus, The percentage of the sale discount is 15%.

First you have to find out what 1/12 of an hour is as well as what 3/10 of a meter is.  


60 divided by 12 = 5


5 = 1/12 of an hour


1000 cm divided by 10 is 100 cm


3/10 so 100 + 100 + 100 = 300 cm or 3/10 of a meter


A snail can go 300 centimeters in 5 minutes.

The speed of the snail, in meters per hour 3 3/5 meters/hour.

Given that, a snail can move 3/10 of a meter every 1/12 hour.

We need to find the speed of the snail, in meters per hour.

What is speed?

Speed tells us how fast something or someone is travelling. You can find the average speed of an object if you know the distance travelled and the time it took. The formula for speed is Speed = Distance ÷ Time.

Now, speed = 3/10 ÷ 1/12

=3/10 × 12/1

=18/5

=3 3/5

Therefore, the speed of the snail, in meters per hour 3 3/5 meters/hour.

The answer would be...
C. p(x) = 8x-20

The profit function, p(x) is the difference between the revenue and cost function of the shirt sales, Hence, the profit function is 8x - 20

Given the Parameters :

Revenue function, R(x) = 15x

Cost function, C(x) = 7x + 20

The profit function can be expressed thus ::

Revenue function - Cost Function

P(x) = R(x) - C(x)

P(x) = 15x - (7x + 20)

P(x) = 15x - 7x - 20

P(x) = 8x - 20

Therefore, the profit function is 8x - 20.

equation
y + 1 = -2/7(x +4)

Answer:

[tex]y-(-1)=-\frac{2}{7}(x-(-4))[/tex]

Step-by-step explanation:

We know that the line passes through (-4,-1) and (3,-3), where [tex](x_{1} ,y_{1} )[/tex] is [tex](-4,-1)[/tex] and [tex](x_{2} ,y_{2} )[/tex] is [tex](3,-3)[/tex].

First, we need to find the slope with the formula

Replacing given points

[tex]m=\frac{-3-(-1)}{3-(-4)}=\frac{-3+1}{3+4}=\frac{-2}{7}[/tex]

Then, we use the slope, one point and the slope-point form

[tex]y-y_{1} =m(x-x_{1} )\\y-(-1)=-\frac{2}{7}(x-(-4))\\ y+1=-\frac{2}{7}x+\frac{8}{7} \\y=-\frac{2}{7}x+\frac{8}{7}-1\\y=-\frac{2}{7}x+\frac{8-7}{7} \\y=-\frac{2}{7}x+\frac{1}{7}[/tex]

The slope-intercept form is

[tex]y=-\frac{2}{7}x+\frac{1}{7}[/tex]

The point-slope form is

What is the doubling time of prices which are increasing by 7 percent per year?

Answers

14.3 years

About 14 years and 4 months

Since it is doubling, it must increase by 100%.
100 divided by 7 = 14.28
Final answer:

The doubling time of prices increasing at a rate of 7% per year can be calculated using the Rule of 70, which states that the doubling time of a variable undergoing exponential growth is approximately 70 divided by the growth rate. Thus, the doubling time for these prices would be about 10 years.

Explanation:

The question pertains to the concept of doubling time in the field of finance and economics, specifically how quickly something (prices, in this case) doubles in size or value at a constant growth rate. The doubling time for a variable growing at a 7% annual growth rate can be calculated using the Rule of 70. This rule states that the doubling time of a variable undergoing exponential growth is approximately 70 divided by the growth rate (in this case, 7).

So, to calculate:
Doubling Time = 70 / 7
Doubling Time = 10 years

This means that the prices will double approximately every 10 years if they increase at a constant rate of 7% per year.

Joanne deposits $4,300 into a one-year CD at a rate of 4.3%, compounded daily. How much interest does she earn?

Answers

This is a compund interest problem which means that the formula to use is
Final Amount = Initial investment (1+(rate/100)/amount of times it is compounded per year)^amount of times compounded per year*amount of years

A = P (1+R/N)^NT

this means that Joanne's final amount is $4488.92 or that she earned $188.92 in interest

In this case, Joanne's interest earned by depositing $4,300 into a one-year CD at a rate of 4.3%, compounded daily can be calculated by plugging the values into the formula.

To calculate the interest earned, use the formula for compound interest: I = P(1 + r/n)^nt - P, where I is the interest earned, P is the principal amount, r is the interest rate, n is the number of times the interest is compounded per time period, and t is the number of time periods.

Substitute the values into the formula to find the interest earned: I = $4,300(1 + 0.043/365)^(365*1) - $4,300

Mary bought 20 bowls and plates for $96. each bowl cost $4.50 and each plate cost $1.50 more than a bowl. she bought more bowls than plates. how many bowls and how many plates did she buy?

Answers

This is a system of equation type of problem.

Let x represent the bowls and y represent the plates.


Your equations will be:

4.50x + 6y = 96

x + y = 20

We can solve this problem by either the substitution method or elimination method.

Substitution method:

1) Solve for x.

x + y = 20

x = 20 - y

2) Substitute x with 20 - y in the other equation.

4.50x + 6y = 96

4.50(20 - y) + 6y = 96

3) Distribute the outside term through the terms inside the parenthesis and simplify the rest of the equation.

90 - 4.50y + 6y = 96

90 + 1.50y = 96

1.50y = 6

y = 4

4) Now that we know the numerical value of y, solve for the numerical value of x by substituting once more.

a) x + 4 = 20

x = 16

b) 4.50x + 6(4) = 96

4.50x + 24 = 96

4.50x = 72

x = 16

*The solution is that:

[tex]x^4-5x^2-14=0~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)[/tex]

Let us consider that

[tex]x^2=y~~~~~\Rightarrow x^4=y^2.[/tex]

which is a quadratic equation in the variable y. The above equation in variable y can be solved using factorization as follows :

[tex]y^2-5y-14=0\\\\\Rightarrow y^2-7y+2y-14=0\\\\\Rightarrow y(y-7)+2(y-7)=0\\\\\Rightarrow (y-7)(y+2)=0\\\\\Rightarrow y-7=0,~~~y+2=0\\\\\Rightarrow y=7,-2.[/tex]

Therefore, we get

[tex]x^2=7\\\\\Rightarrow x=\pm\sqrt7[/tex]

and

[tex]x^2=-2\\\\\Rightarrow x=\pm\sqrt{-2}\\\\\Rightarrow x=\pm\sqrt2i,~~~~~~~~~~~~~[\textup{where }i=\sqrt{-1}][/tex]

Answers

After the split, Janine had 960 share worth $34.74. Since they doubled the amount of share, but decrease the amount of each share, Jane didn't gain or lose any money during the event.
Final answer:

Janine held 940 shares after the split. The post-split price per share was $34.74. The split was a monetary non-event as the total value of Janine's shares remained the same.

Explanation:

A 2-for-1 split means that for every one share of stock owned, an investor receives two shares in return. In this case, Janine had 470 shares before the split. After the split, she would have 470 x 2 = 940 shares.

The pre-split price per share was $69.48. Since the split was 2-for-1, the post-split price per share would be $69.48 / 2 = $34.74.

To show that the split was a monetary non-event for Janine, we can calculate the total value of her shares before and after the split. Before the split, Janine's shares were worth 470 x $69.48 = $32,621.60. After the split, her 940 shares would be worth 940 x $34.74 = $32,621.60. Therefore, the total value of her shares remained the same.
