Y = -1 + 3x... y1= 2, y2=5... so the 20th term will be 59. There will be ten pairs (i.e 2,59 equal 61... 5,56 equal 61) so multiply this 61 by 10 and your sum will be 610

If f(x)=2x^2-5 and g(x)=x^2-4x-8, find (f-g)(x)
Marianna [84]
 (f-g)(x) is equivalent to f(x) - g(x)

So that would be (2x²-5) - (x²-4x-8) = 2x² - x² + 4x + 8 - 5 = x² + 4x + 3

Hope this helps.

Use the information to form a ratio... 6:8 or 6/8. Now set it equal to a ratio per 100...

6/8 = x/100

Cross multiply

8x = 600
x = 600/8

Write an exponential function in the form y=ab^2 that goes through points (0,18) and (3, 9216)
Alex_Xolod [135]

Answer:

  y = 18·8^x

Step-by-step explanation:

We assume you want a model that looks like y = ab^x.

To find the values of "a" and "b", you can fill in the given numbers and solve the system of equations:

  18 = a·b^0

  9216 = a·b^3

The first equation tells you ...

  18 = a

Dividing the second equation by the first gives ...

  9216/18 = (a·b^3)/(a·b^0) = b^3

  512^(1/3) = b = 8

The exponential function is ...

  y = 18·8^x
