Step-by-step explanation:
Answer:
12.1
Step-by-step explanation:
y=a(1/2)^t/h
270=410(1/2)^t/20
Divide both sides by 410
0.6585365854 = (1/2)^t/20
Log Both sides
Log(0.6585365854) / Log(1/2)
.6026645024= t/20
20 x .6026645024 = t
12.05329005 to the nearest tenth is 12.1 = t
Formula for finding circumference of a circle is 2πr.
Step-by-step explanation:
- The given question says what is the circumference of a circle that is 9cm.
- As radius is required for finding circumference of a circle, the formula is 2πr.
- Therefore taking the formula and substituting radius (r)= 9 cm. We get 2πr as 2×π×9 = 18π cm OR
- If we substitute the value of π as 3.14 we will get⇒ 2×3.14×9= 56.52 cm.
- So the circumference of the given circle would be 18π or 56.52 cms.
Answer: Your question options are not legible but the inverse of the function is f-1(x) = (x + 2) / 2
Step-by-step explanation:
y = 2x + 2
Make x the subject of formula:
2x = y - 2
x = (y - 2) / 2
Now substitute y for x:
(x - 2) / 2
Y = (x - 2) / 2 is the inverse equation of the above graph.
For 2 2/3 it’s the 6th line from 2
For 1 5/9 it’s the 5th line from 1
Hope this helps!
