Physicsforums.com has step by step explanation but here is example 
y=-9e-19x^6+2e-14x^5-2e-10x^4+1e-06x^3-0.0027x^2+3.5222x-1656.5
shorthand =(10^-9)-(19x*x^6)etc..... go to physics sight it breaks different examples down. sorry i couldnt give u direct answer but i always have to find example problems to walk me thru it as needed

Let e^-3x be u,
10u^-2=5u
10/u^2=5u
5u^3=10
u^3=10/5
u=1.25992105
e^-3x=1.25992105
-3x=0.2310490602
x=-0.0770
Method 2
10e^6x=5e^-3x
10e^6x-5e^-3x=0
5e^-3x(2e^9x-1)=0
2e^9x-1=0
2e^9x=1
e^9x=1/2
9x=loge1/2
x=(loge1/2)/9
=-0.0770

The product of two consecutive odd intergers is 1 less than four times thier sum. Find the two integers.
seraphim [82]
Consecutive odd integers are 2 apart
they are x and x+2
the product (x times (x+2)) is 1 less than  4 times their sum

x(x+2)=-1+4(x+x+2)
x^2+2x=-1+4(2x+2)
x^2+2x=-1+8x+8
x^2+2x=8x+7 minus (8x+7) from both sides [tex]x^2-6x-7=0

what  numbers multliply to get -7 and add to get -6?
-7 and 1
(x-7)(x+1)=0
set equal to 0
x-7=0
x=7

x+1=0
x=-1

so the x can be 7 or -1
the other number (x+2) can be 7 or 1

test each

7 and 9
7(9)=-1+4(7+9)
63=-1+4(16)
63=-1+64
63=63
true


-1 and 1
-1(1)=-1+4(-1+1)
-1=-1+4(0)
-1=-1+0
-1=-1
true



the 2 integers can be 7 and 9 or -1 and 1 (both pairs of numbers work)

Convert 491 into binary number
sergij07 [2.7K]

Answer:

111101011 subscript 2

Step-by-step explanation:

491 / 2 = 245 , 1 remainder

245 / 2 = 122 , 1 remainder

122 / 2 = 61 , 0 remainder

61 / 2 = 30 , 1 remainder

30 / 2 = 15 , 0 remainder

15 / 2 = 7 , 1 remainder

7 / 2 = 3 , 1 remainder

3 / 2 = 1 , 1 remainder

1 / 2 = 0 , 1 remainder

Now, we're going to put the remainders together in reverse order to get the final answer.

111101011 ---> this is the final solution

See the image below for how you would write 111101011 subcript 2.

Refer to the equation 2x − 6y = 12 Create a table of values for at least 4 points. Show your work
natka813 [3]

Answer: The table and figure are given below,

Solution:

The given equation is 2x-6y=12.

put x=0 in the equation.

2(0)-6y=12

-6y=12

y=-2

Similarly find the values of y at different values of x. The values are shown in the table.

From table it is notices that the value of y=-2 for x=0, y=-1 for x=3, y==-3 for x=-3, y=0 for x=6.

Plot these points in the coordinate plane and joint them by a straight line.

The gra his shown in below figure.
