What are additive inverses?

A complex number is said to be additive if  the sum of a complex number and its additive inverse is zero.

For instance the the additive inverse of the complex number a+bi is -a-bi.

Given the comlex number -2 + 8i, the additive inverse is expressed as:

Additive inverse = -(-2 - 8i)

Additive inverse = 2 + 8i

Hence the additive inverse of the complex number is 2+ 8i

You have $90 in your bank account. each week you plan to deposit $6 from your allowance and $10 from your paycheck. The equation b=90+(10+6)w gives you the amount b in your account after w weeks from now will you have $195 in your bank account

Answers

Answer: After 6.5625 (or 6 1/2) weeks

Step-by-step explanation: You have to replace b with the 195.
195 = 90 + (10+6)w

Subtract 90 from both sides to get

105=(10+6)w

Simplify

105=16w

Divide both sides by 16 to get 6.5625, or 6.5

Can you help me with question 3 pls

Answers

The answer is m= 103° because Angle 1 and angle 3 are vertical angles therefore they are congruent which meant angle 1 = angle 3

Answer:

The m<3 is going to be equal to the m<1 due to the vertical angles theorem. Therefore if we find the m<1 then we can find the m<3

In this case, it is given to us and therefore m<3 = 103°

Jose is a botanist studying production of coconuts by two different groups of his
coconut palms. He noticed that Group 1 of trees produced 25 percent more coconuts
than Group 2 did. Based on Jose's observation, if Group 1 produced 165 coconuts,
how many coconuts did Group 2 produce?

Answers

Answer: 132

Step-by-step explanation:

Since we are informed that Group 1 of trees produced 25 percent more coconuts than Group 2 did and that Group 1 produced 165 coconuts, the number of coconuts that Group 2 produce will be:

= [100 / (100 + 25)] × 165

= 100/125 × 165

= 0.8 × 165

= 132

Group 2 produced 132 coconuts.

the IQR for the Panthers, 40.
Panthers, 40.

Answers

Answer:

C. The interquartile range (IQR) for the Wolverines, 30, is less than the IQR for the Panthers, 40.

Step-by-step explanation:

The interquartile Range (IQR) of a data describes or measures how spread out the data values are.

Thus, IQR = Q3 - Q1. which is the range of the rectangular box in the box plot given.

Thus,

IQR for the Wolverines = 85 - 55 = 30

IQR for the Panthers = 90 - 50 = 40

Therefore, comparing their spreads, the most appropriate statement is:

C. The interquartile range (IQR) for the Wolverines, 30, is less than the IQR for the Panthers, 40.

Marcy's Cafe has regular coffee and decaffeinated coffee. This morning, the cafe served 60 coffees in all, 33 of which were regular. What percentage of the coffees were regular?

Answers

Answer:

55%

Step-by-step explanation:

Percentage of regular coffees = [tex]\frac{33}{60}[/tex] × 100%

                                                  = 55%

Answer:

55%

Step-by-step explanation:

To find the percentage of regular coffees, divide 33 by 60, and multiply that by 100:

(33/60) x 100

0.55 x 100

= 55

So, 55% were regular

Ifangle1∠ 1 and angle2∠ 2 are complementary, find the measure of x and the measures of the angles when LaTeX: m\angle1=\left(6x+5\right)^\circm ∠ 1 = ( 6 x + 5 ) ∘ and LaTeX: m\angle2=\left(8x+15\right)^\circm ∠ 2 = ( 8 x + 15 ) ∘ ?

Answers

Answer:

x = 5

Step-by-step explanation:

The sum of two complementary angle is 90 degrees. Given the following complementary angles;

<1 = 6x + 5

<2 = 8x + 15

<1 + <2 = 90 (complementary angles)

6x + 5 + 8x + 15 = 90

14x + 20 = 90

14x = 90-20

14x = 70

x = 70/14

x = 5

Hence the measure of x is 5

Ama is sliding down the Super Mega Ultra Slide at a local amusement park. She slides at a rate of 8 m/s downward, and after 3 seconds is 5 m off of the ground. How many seconds will it take her to slide to the ground from the top? Round your answer to the nearest tenth. *

Answers

Answer:

3.0625 seconds

Step-by-step explanation:

From the question,

✓She slides at a rate of 8 m/s downward

✓after 3 seconds is 5 m off of the ground

We can calculate the the number of seconds she will use to get to the ground by

Velocity= distance/time

Time= distance/ velocity

=5/8 seconds

=0.625seconds

To know how many seconds it will take her to slide to the ground from the top can be calculated as

( 3seconds + 0.625 seconds)

= 3.0625 seconds
