Find(f+g)(x) for the following functions. f(x) = 12x2 + 7x + 2 g(x) = 9x + 7
Nimfa-mama [501]

Answer:

(f + g)(x) = 12x² + 16x + 9 ⇒ 3rd answer

Step-by-step explanation:

* Lets explain how to solve the problem

- We can add and subtract two function by adding and subtracting their

 like terms

Ex: If f(x) = 2x + 3 and g(x) = 5 - 7x, then

     (f + g)(x) = 2x + 3 + 5 - 7x = 8 - 5x

     (f - g)(x) = 2x + 3 - (5 - 7x) = 2x + 3 - 5 + 7x = 9x - 2

* Lets solve the problem

∵ f(x) = 12x² + 7x + 2

∵ g(x) = 9x + 7

- To find (f + g)(x) add their like terms

∴ (f + g)(x) = (12x² + 7x + 2) + (9x + 7)

∵ 7x and 9x are like terms

∵ 2 and 7 are like terms

∴ (f + g)(x) = 12x² + (7x + 9x) + (2 + 7)

∴ (f + g)(x) = 12x² + 16x + 9

* (f + g)(x) = 12x² + 16x + 9

Now Chris has 9
Kevin has 24
24-9=15
Hope this helps:)

Ferris wheel has a diameter of 60 ft. How far will a rider travel during a 5 minute ride if the wheel rotates once every 15 seco
Neporo4naja [7]

Answer:

3769.92 ft

Step-by-step explanation:

The diameter of the wheel, d= 60 ft

We know the perimeter of the wheel is,

= πd

= 3.1416*60

= 188.496 ft

Wheel travel for 5 minutes. So the wheel travel,

= 5*60

= 300 sec

The wheel rotates in every 15 seconds. So the wheel rotates,

= 300/15

= 20 times

In one rotation, the wheel travels its perimeter. so is 5 minutes it travels,

= 188.496*20

= 3769.92 ft
