Step-by-step explanation:

<u>Step 1:  Find </u>u_1

u_1=u_1-u_0

u_1 = 3(1)^2-2(1) - (3(0)^2-2(0))

u_1 = 3(1) - 2 - (0)

u_1=3-2

u_1 = 1

Answer:  u_1 = 1

<u>Step 2:  Find </u>u_6

u_6 = u_6-u_5

u_6=(3(6)^2-2(6))-(3(5)^2-2(5))

u_6=(3(36)-12)-(3(25)-10)

u_6 = (108-12) - (75-10)

u_6=96 - 65

u_6=31

Answer:  u_6=31

Answer:

u1 = 1

u6 = 31

un = 1 + 6(n - 1)

Step-by-step explanation:

Sn = 3n² - 2n

u1 = S1

3(1)² - 2(1)

3 - 2

1

u6 = S6 - S5

[3(6)² - 2(6)] - [3(5)² - 2(5)]

96 - 65

31

un = a + (n - 1)d

u6 = a + 5d

31 = 1 + 5d

5d = 30

d = 6

un = 1 + 6(n - 1)

Please help. Write the equation of the graph. (Do not use spaces. Use ^ to represent exponents. Example 2^3 is 23.)
lana66690 [7]
This graph has a horizontal asymptote so it is an exponential graph. It also passes through two points (0,-2) and (1,3). The horizontal asymptote is at y=-3.
The unchanged exponential equation is y=a(b)^x +k
For exponential equations, k is always equal to the horizontal asymptote, so k=-3.
You can check this with the ordered pair (0,-2). After that plug in the other ordered pair, (1,3).
This gives you 3=a(b)^1 or 3=ab. If you know the base the answer is simple as you just solve for a.
If you don't know the base at this point you have to sort of guess. For example, let's say both a and b are whole numbers. In that case b would have to be 3, as it can't be 1 since then the answer never changes, and a is 1. Then choose an x-value and not exact corresponding y-value. In this case x=-1 and y= a bit less than -2.75. Plug in the values to your "final" equation of y=(3)^x -3.
So -2.75=(3^-1)-3. 
3^-1 is 1/3, 1/3-3 is -8/3 or -2.6667 which is pretty close to -2.75. So we can say the final equation is y=3^x -3. 
Hope this helps! It's a lot easier to solve problems like these given either more points which you can use system of equations with, or with a given base or slope.

What is the value of C in the equation 12 C minus 53 equals 91
Amiraneli [1.4K]
12c - 53 = 91

First add 53 to each side.  This cancels it out on the left (-53 + 53 = 0)

12c = 91 + 53
12c = 144

Now divide by 12 on each side.  This cancels the 12 on the left (12/12 = 1)

c = 144/12
c = 12
