Answer:
more than likely its
f(1) -5
Step-by-step explanation:
The function is y = 640/ 4^x and the graph decreases exponentially from 640 (for x =0) and asymptotically approacdhes zero (when x becomes larger and larger). This is an exponential decay.
Answer: the last option of the list. The graph will show exponential decay
Answer:
Step-by-step explanation:

(x + 7)° = (15 + 7)° = 22°
(4x + 8)° = (4*15 + 8)° = (60 + 8)° = 68°
Answer:
longest side=3.6
let ratio 3:5:6:9be 3x,5x,6xand9x
perimeter= sum of all side
9.2=3x+5x+6x+9x
9.2=23x
x=9.2÷23
x=0.4
9x=9×0.4=3.6
6x=6×0.4=2.4
5x=5×0.4=2
3x=3×0.4=1.2
Answer:
3/8
Step-by-step explanation:
1- 1/4 +(1/2 x 3/4)
1. subtract 1/4 to get 3/4 (how much time she has left in class).
2. multiply 3/4 by 1/2 to find how much half of 3/4 is.
3. Half of 3/4 is 3/8 so that's how much time she spent on the balance beam.
