Given the expression (8+3i)+(-2+i)

We need to simplify it.

(8+3i)+(-2+i)

First we have to remove the parenthesis.

8+3i-2+i

As we know that multiplication of positive and negative is negative.

Now we will add or subtract like terms. Like terms means here i with i and constant term with constant term. So here we will add 3i and i. Also subtract 2 from 8.

8-2 +3i+i

6+4i

We have got the required answer.

The simplified answer is 6+4i.

The volume of a cone is 18π cubic feet. If the height of the cone is 6 ft, what is the radius of the cone? (V = 1 3 πr2h)

svetoff [14.1K]

Answer:

Volume = 1/3πr^2h

18π = 1/3πr^2 x 6

18 = 2r^2

9 = r^2

r = 3 ft.

One photo shop charges $0.36 per print. Another photo shop charges $2.52 plus $0.08 per print. Juan finds that the cost of print

koban [17]

Juan have to print 9 photos.

Explanation

Suppose, Juan have to print $x$ number of photos.

First photo shop charges $0.36 per print. So, the total cost to print $x$ number of photos in this shop $=0.36x$ dollar.

Second photo shop charges $2.52 plus $0.08 per print. So, the total cost for printing $x$ number of photos $= (2.52+0.08x) dollar$

As, the cost of printing is the same at both shops, so.....

$0.36x=2.52+0.08x\\ \\ 0.36x-0.08x= 2.52\\ \\ 0.28x=2.52\\ \\ x=\frac{2.52}{0.28}=9$

So, Juan have to print 9 photos.

14 + 10y ≥ 3(y + 14) A. y ≥ –4 B. y ≥ 4 C. y ≥ 8 D. y ≥ 6

arsen [322]

Answer:

Step-by-step explanation:

Given

14 + 10y ≥ 3( y + 14) ← distribute

14 + 10y ≥ 3y + 42 ( subtract 3y from both sides )

14 + 7y ≥ 42 ( subtract 14 from both sides )

7y ≥ 28 ( divide both sides by 7 )

y ≥ 4 → B
