A complex number is said to be additive if the sum of a complex number and its additive inverse is zero. The additive inverse of the complex number is 2+ 8i
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

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. *
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

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
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
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°

Which statement is the most appropriate comparison of the spreads?
A. The median for the Wolverines, 80, is more than the median for the
B. The interquartile ranges (IQRS) for the Wolverines and Panthers
C. The interquartile range (IQR) for the Wolverines, 30, is less than
D. The range forthe Wolverines, 30, is less than the range for the
Panthers, 70.
are both 30.
the IQR for the Panthers, 40.
Panthers, 40.
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.

If y varies directly with x, and y = 15 when x = 20, find y when x = 75.
Answer:
5
Step-by-step explanation:
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 ) ∘ ?
Answer:
x = 5Step-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

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?
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.
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?
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
