Mathematics
1 answer:
professor190 [17]4 years ago
6 0

Answer:

a. 2^4 or 16

b. 324

Step-by-step explanation:

a. I think you can take 4 and put it as the exponent using properties of logs. so it becomes ln 2^4

b. you use the same property and get

ln 6^2 + ln 3^2 and use the addition/multiplication property one to combine them and get

ln 6^2 * 3^2

or ln 36 * 9

or ln 324

hopefully that works

Find the value of i77.<br> A) 1 <br> B) i <br> C) −1 <br> D) −i
Colt1911 [192]

assuming you mean i^{77} where i=\sqrt{-1}

ok, notice a pattern in the exponent

i^1=i=\sqrt{-1}

i^2=-1

i^3=-\sqrt{-1}=-i

i^4=1

i^5=i=\sqrt{-1}

hum, so it goes 1,2,3,4, then repeats

ok, so every 4, the cycle repeats

how far  up is 77 from a multipule of 4?

4*19=76

76 is 1 away from 77

so i^{77}=(i^{76})(i^1)=

(i^4)^{19}(i)=(1)^{19}i=i

the answer is B

The length of a room is 4 feet less than twice its width. The perimeter of
AlladinOne [14]

L=2W-4

PERIMETER=2L+2W

58=2(2W-4)+2W

58=4W-8+2W

58=6W-8

6W=58+8

6W=66

W=66/6

W=11 ANS. FOR THE WIDTH.

L=2*11-4

L=22-4

L=18 ANS. FOR THE LENGTH.

PROOF:

58=2*18=2*11

58=36+22

58=58

3x - 2y = -18 use the table of vaules to graph the line
docker41 [41]

Answer:

Given the equation of line :  3x -2y = -18

Table values:

x                  y

0                  9

2                  12

4                   15

6                   18

-6                  0

Now, plot these points (0,9), (2, 12), (4, 15) , (6, 18) and (-6, 0) on the co-ordinate planer, to graph the the line.

You can see the graph of the given equation as shown below.
