Answer:

Dear user,

Answer to your query is provided below

x + yi = 4 + 3i

Step-by-step explanation:

(2 − 3i) + (x + yi) = 6

=> 2 + x - 3i + yi = 6

=> (x + 2) + (y - 3)i = 6 + 0i

Equating coefficients:

x + 2 = 6 => x = 4

y - 3 = 0 => y = 3

Therefore x + yi = 4 + 3i

If a fourth plant produces 400 widgets in 60 days, which statement is true?
USPshnik [31]
The complete question in the attached figure

the statements are
1) It makes less than plant B
2) It makes the same as plant A
3) It makes more than plant C

we know that
<span>analyzing the graph

</span>plant A
for x=40  y=100
for x=50   y=200
that means 
the production in 10 days is 100 widgets
then
the production in 60 days will be 6*100----> 600 widgets
so
plant A production  > plant fourth production
plant fourth production < plant A production

plant B
for x=40  y=0
for x=60   y=100
that means 
the production in 20 days is 100 widgets
then
the production in 60 days will be 3*100----> 300 widgets
so
plant B production  < plant fourth production
plant fourth production > plant B production

plant C
for x=20  y=0
for x=40   y=100
that means 
the production in 20 days is 100 widgets
then
the production in 60 days will be 3*100----> 300 widgets
plant C production  < plant fourth production
or 
plant fourth production > plant C production

therefore 

the answer is 
3) It makes more than plant C

There are approximately 3,000 bass in a lake. The population grows at a rate of 2% per year. Round answers to the nearest tenth.
Tamiku [17]

Answer:

years 1–4: 62.4 bass per year

years 5–8: 67.6 bass per year

Step-by-step explanation:

If the population in year n is ...

 p(n) = 3000·1.02^n

then the average rate of change from year 1 to year 4 is ...

 (p(4) -p(1))/(4 -1) = 3000(1.02^4 -1.02^1)/3 = 1020·(1.02^3 -1) ≈ 62.4

The average rate of change for years 1–4 is 62.4 bass per year.

For years 5–8, the rate of change is similarly computed:

 (p(8) -p(5))/(8 -5) = 3000(1.02^8 -1.02^5)/3 = 1000·1.02^5·(1.02^3 -1) ≈ 67.6

The average rate of change for years 5–8 is 67.6 bass per year.

The sum of two numbers is 87. The second number is 6 more than twice the first number. Find an equation that expresses this situ
KiRa [710]

Answer:

x+2x+6=87

Step-by-step explanation:

let x represent the first number. 2x+6 would represent the second number since it's 6 more than (which would be addition) twice the first number (so you'd multiply the first number (which is represented by x) by 2. then, you'd set up the equation to be equal to 87.

so, the equation would be:

x+2x+6=87
