Please I need help on a couple problems!

Mathematics
1 answer:
Dafna1 [17]2 years ago
5 0

Answer:

I will set this up for you and you work the math.

 

f(n) = f(n - 1) + 3

 

n = 7

 

f(7) = f(7 - 1) + 3 = f(6) + 3

 

Do the same for f(6).

 

f(6) = f(5) + 3 ⇒

 

f(7) = f(5) + 3 + 3

 

Similarly,  

 

f(5) = f(4) + 3 ⇒

 

f(7) = f(4) + 3 + 3 +3

 

Do you see the pattern emerging here?  Keep going until you are down to

 

f(2) = f(1) + 3 = 6 + 3 = 9

 

Then carefully plug the intermediate answers into their proper place in

 

f(7) = f(6) + 3

If 2a+ 2/a =4, what is the value of 2a^2− 2/a^2 ?
aliina [53]

Answer:

0

Step-by-step explanation:

2a+ 2/a =4

Multiply each side by a to clear the fraction

a( 2a+ 2/a) =4*a

Distribute

2a^2 +2 = 4a

Subtract 4a from each side

2a^2 -4a +2 = 4a-4a

2a^2 -4a +2 =0

Divide by 2

2/2 a^2 -4a/2 +2/2 =0/2

a^2 -2a +1=0

Factor

(a-1) (a-1) =0

Using the zero product property

a=1

2a^2 -2/a^2

2(1)^2 -2/1^2

2-2

Two linear functions are shown. Which function has the greater initial​ value?
tangare [24]

Answer:

Function A has the greater initial value because the initial value for Function A is 6 and the initial value for Function B is 3.

Step-by-step explanation:

✔️Function A:

Initial value = y-intercept (b)

y-intercept is the value of y, when the corresponding value of x = 0

From the table, y = 6 when x = 0.

The y-intercept of function A = 6

Therefore, initial value for Function A = 6

✔️Function B:

y = 4x + 3 is given in the slope-intercept form, y = mx + b.

b = y-intercept = initial value.

Therefore

Initial value for Function B = 3

✔️Function A has the greater initial value because the initial value for Function A is 6 and the initial value for Function B is 3.
