## itsmichelle29 one year ago A video game sets the points needed to reach the next level based on the function g(x) = 10(2)x − 1, where x is the current level. The hardest setting promises to multiply the points needed in each level according to the function h(x) = 2x. How many points will a player need on the hardest setting of level 5? 10 points 160 points 1600 points 16000 points

sorry I don't understand your formula: g(x) = 10(2)x − 1

4. Michele_Laino

is your formula like this: $\Large g\left( x \right) = 10 \times {2^{x - 1}}$

5. itsmichelle29

yup like that

the points needed to reach the fifth level are: $\Large g\left( 5 \right) = 10 \times {2^{5 - 1}} = 10 \times {2^4} = 10 \times 16 = ...$ the hardest setting multiply those points by $\Large h\left( 5 \right) = 2 \times 5 = 10$ so the requested poiints are: $\Large g\left( 5 \right) \times h\left( 5 \right) = ...?$

8. itsmichelle29

correct

9. Michele_Laino

hint: $\Large g\left( 5 \right) \times h\left( 5 \right) = 160 \times 10 = ...?$

correct!

12. Michele_Laino

that's right! It is 1600
