Answers

Answer 1

Complex numbers are written in the form of a+ib and the simplified form of the expression is 58 which is a real number.

Complex number

Complex numbers are square root of negative numbers. For instance;

√-1 = i

Given the equation

(2 + √-25)(4 - √-100)

From the given expression

√-25 = 5i

√-100 = 10i

Substitute

(2+5i)(4-10i)

Expand

2(4) -2(10i) + 5(4i) - 5i(10i)

8 - 20i + 20i - 50i²

8 - 50(-1)

8 + 50

58

Hence the simplified form of the expression is 58

Tristan used his graduation money of $2000 to set up a savings account. He wants to determine which investment would make the most money.
Find the amount of money each investment would yield after 5 years.

How much would Tristan earn with Account A: 5.7% interest compounded monthly

Answers

The amount that Tristan would earn in 5 years is  $657.30.

How much would Tristan earn?

When an amount is compounded monthly, it means that both the amount invested and the interest that has already accrued increases in value every month or 12 times in a year.

The first step is to determine the future value of the investment.

The formula for calculating future value:

FV = P (1 + r)^nm

Where:

FV = Future value P = Present value R = interest rate : 5.7% / 12 = 0.475%m = number of compounding = 12N = number of years

$2000 x (1.00475)^(12 x 5)

$2000 x (1.00475)^60

= $2,657.30

Amount he would earn = $2,657.30 - $2,000 = $657.30

One of the legs of a right triangle measures 2 cm and its hypotenuse measures 4 cm. Find the measure of the other leg. If necessary, round to the nearest tenth.

Answers

Answer: 3.5

Step-by-step explanation:

To find the length of the missing leg, we need to use the Pythagorean Theorem (a^2 + b^2 = c^2 where c is the hypotenuse)

1) Plug in numbers

2^2 + b^2 = 4^2

2) Square

4 + b^2 = 16

3) Flip Equation and Subtract

16 - 4 = b^2

16 - 4 = 12

4) Square Root of 12

The square root of 12 is ~3.46, so you need to round to the nearest tenth, which is 3.5

22. a. In 1990, Nadezhda Ryashkina set the record for the 10,000 m race-walking event. She finished this race in 41 minutes 56.23 seconds. What was Ryashkina's average walking rate, in meters per second?​

Answers

Given the distance covered and the time elapsed, Ryashkina's average walking rate is approximately 3.97 meters per second.

What was Ryashkina's average walking rate?​

Rate or speed is expressed as distance walked or traveled per unit time.

R = s/t

Given the data in the question;

Distance covered s = 10,000mTime elapsed t = 41 minutes 56.23 secondsRate r = ?

First convert 41 minutes to seconds.

⇒ 41min = ( 41 × 60 )s = 2460sec

Now, Elapsed time t = 2460s + 56.23s = 2516.23 second

Next, we determine the rate.

R = s / t

R = 10000m / 2516.23 s

R = 3.97m/s

Given the distance covered and the time elapsed, Ryashkina's average walking rate is approximately 3.97 meters per second.

What is −10 + |−4| − |−12|?

Answers

Answer:

-18

Step-by-step explanation:

-10 + |-4| - |-12|       Since there are the | |, then any negative number inside would become a positive as it will become its absolute value, which for -4, would be 4, because it is 4 spots away from the 0 on a number line and vice versa.

-10 + 4 - 12   Answering from left to right,

-10 + 4, if you would rather make it so they are both equal, you change the + to the opposite which would be - and change the 4 back to a negative because that is what it would be if you changed the equation to be subtraction instead to be easier as they would both be negatives now, so you would subtract -10 - -4 and get -6.

-6 - 12. Again, switch the - to the opposite, which is +, and then make 12 the opposite that it was before so they both share the same symbol, making it

-6 + -12, which would be -18.

A car rental agency rent 190 cars per day at a rate of $40 per day for each one dollar increase in rate five fewer cars are rented at what rate should the cars be rented to produce the maximum income?

Answers

The rate that the cars should be rented to produce the maximum income is: 41 Dollars/Day, Maximum income 7615.

Rate and maximum income

Let y represent the  income

Let  x  represent the increase in rental price after increasing the rental price is 40+x.

Let 190-5x represent the number of cars rental after a rental price increase

Income expression

y=(190-5x) (40+x)

Let differentiate y with respect to x and set y' =0 to determine the maximum income

Hence,

y=(190-5x) (40+x)

=(190) (40) + 190 (x) -5x(40) -5x-(x)

=7600 +190x-200x-5x²

y= -5x² +10x+7600

Differentiate with respect to x

y'=d/dx ( -5x² +10x+7600)

y'=-10x+10x

set y'=0

-10x+10=0

10x=10

x=10/10

x=1

Maximum Rate =40+x

=40+1

=41 Dollars/Day

Maximum Income is

y= ( -5x² +10x+7600)

=(−5(1)²+10(1)+7600)

=−5(1)+10+7600

=5+10+7600

Oscar is building a fence and purchases three boards that each measure
2.91 meters long. How many meters of fence board did Oscar purchase?

Answers

Oscar bought 8.73 meters of fence board to build the fence.

The metric system and the International Systems of Units both use the metre (m), also spelt as meter, as the basic unit of length (SI). In the British Imperial and American Customary systems, it is equivalent to roughly 39.37 inches.

A fence is a building used to enclose a space, usually outdoors. It is often made of posts joined by boards, wire, rails, or nets.

Oscar purchases three boards that measure 2.91 meters long each to build a fence.

Let say the length of one board be x = 2.91 meters.

Then the total length of fence board Oscar purchases is:

= 3x = 3 × 2.91 meters = 8.73 meters

Hence Oscar purchased 8.73 meters of fence board.

Answers

Answer: The probability that a student chosen at random has a cat and a dog is; P(cat and dog) = 9/25.

Step-by-step explanation:

According to the question, the total number of students is; 25.

15 of them have a cat

16 of them have a dog

while, 3 of them have neither

The information above are drawn in a Venn diagram in the attached image.

where, x = number if students who own a cat and a dog.

Consequently, the total number of students who own a cat, a dog, both or neither is as follows;

15-x + x + 16-x + 3 = 25.

-x = 25 - 34

In essence, x = 9

Therefore, the number of students who own a cat and a dog is 9.

The probability that a student chosen at random has a cat and a dog is therefore;
