They started at 453, then climbed 162, so now they are at:
453 + 162 = 615 feet.
They then cllmb another 207 feet to get to:
615 + 207 = 822 feet.
They then descend ( climb down) 285 feet.
822 - 285 = 537 feet.
Now they need to get back tot he original 453,
so they have to descend:
537 - 453 = 84 more feet.
The answer is C.
1.) You have 12 toppings. You choose one topping--that leaves you with 11 toppings. You choose another--that leaves 10. 12×11×10 = 1,320.
Multiply 1,320 topping choices by 6 cheeses to get 7,920 total combinations.
2.) (Though I'm less sure of these)
CDs: 6×5×4×3×2 = 720
Cassettes: 5×4 = 20
DVDs: 8×7×6×5 = 1680
Answer:
-0.399
Step-by-step explanation:
f^-1(1024)=(2*1024-2/5)^-1= 0.000488
f(0.000488)=2*0.000488-2/5= -0.399
The answer for the question is option 2
