10^1=10

10^2=100

10^3=1000

10^4=10,000

The power multiplies the number by itself the number of the power.  When multiplying 10 to the power of any number, just make the number of 0's in the final number equal to the exponent.

10^34 will be a 1 with 34 zeros on the end.

Write the equation of the line that passes through the points (8,−7) and (−9,7). Put your answer in fully reduced point-slope fo
Sunny_sXe [5.5K]

Answer:

y + 7 = (-14/17)(x - 8)

Step-by-step explanation:

We want the equation of this line in the point-slope form y - k = m(x - h).

We are given two points (8, -7) and (-9, 7), and may arbitrarily choose one of them to serve as the point (h, k) in the point-slope form shown above.  Then the other point is represented by (x, y) in the point slope form shown above:

Let (h, k) be 8, -7) and let (x, y) be (-9, 7).  Then,  y - k = m(x - h) becomes:

7 - (-7) = m(-9 - 8), so that 14 = m(-17), and the slope is thus m = -14/17

The desired equation is then y + 7 = (-14/17)(x - 8) (which is in point-slope form).  

Another way to get this result would be to find m in the usual way:

          rise           14

m = ------------- = --------- = -14/17 (same as before).

           run           -17

50 points!!! What is the sum of the first 8 terms of the geometric series?
olga55 [171]

Answer:

<u>Sum of the 8 terms = 69.19</u>

Step-by-step explanation:

The sum of the geometric series is S

s=\frac{a(1-r^n)}{1-r}

Where: a is the first term

            n is the number of terms

            r is the constant ratio.

For the giving geometric series: 120 - 80 + 160/3 - 320/9 + ...

a = 120 , n = 8

r = -80/120 = -2/3

∴ s = \frac{120(1-(\frac{-2}{3})^8) }{1-(\frac{-2}{3}) } = \frac{50440}{729}=69\frac{139}{729}=69.19

The sum of two numbers is nine if one number is subtracted from the other the result is -1 find the numbers
Anestetic [448]
Lets make x and y the two numbers. The sum of the two numbers (x and y) is 9 means that they add to 9. So the first equation is 

x+y = 9

Let's isolate y by subtracting x from both sides. That gives us

y = 9-x

The other bit of information given is "if one number is subtracted from the other, the result is -1", which means we have this other equation

x-y = -1

From here, substitute y for 9-x

x-y = -1
x-(y) = -1
x-(9-x)=-1
x-9+x=-1
2x-9 = -1
2x-9+9 = -1+9
2x = 8
2x/2 = 8/2
x = 4

If x = 4, then y is...
y = 9-x
y = 9-4
y = 5

Therefore, the two numbers are 4 and 5. They add to 9
4+5 = 9
and they subtract to -1
4-5 = -1

Final Answer: 4 and 5
