Answer:
exponential decay
Step-by-step explanation:
The function is in the form
y = ab^x where a is the initial value and b is the growth or decay rate
If b >1 then it is growth
b < 1 then it is decay
f(x) = 5(2/3)^x
a = 5
b = 2/3
2/3 <1 so it is decay
Number 1 is point p
Number 2 62.5 points

Answer:
4. w = 31
5. x = 50
Step-by-step explanation:
To find the values of variable w and x in the given triangles above, recall that the sum of angles in a triangle = 180°.
Therefore,
==>w° + w° + (4w - 6)° = 180°
Solve for w
w + w + 4w - 6 = 180
6w - 6 = 180
Add 6 from both sides
6w = 180 + 6
6w = 186
Divide both sides by 6
w = 186/6
w = 31
==>Also, x° + x° + (x + 30)° = 180
x + x + x + 30 = 180
3x + 30 = 180
Subtract 30 from both sides
3x = 180 - 30
3x = 150
Divide both sides by 3
x = 150/3
x = 50

Part B
176
Step-by-step explanation:
Total: 65+110+75 = 250
P(O) = 75/250 × 100 = 30%
P(A) = 110/250 × 100 = 44%
P(K) = 65/250 × 100 = 26%
