Answer:
Compound Interest Formula Solved For Rate:
log (1 + rate) = {log(total) -log(Principal)} ÷ Years
log (1 + rate) = {log(5,800) -log(5,000)} ÷ 5
log (1 + rate) = [3.7634279936 -3.6989700043] / 5
log (1 + rate) = 0.0644579893 / 5
log (1 + rate) = 0.0128915979
Then we raise 10 to the power of 0.0128915979 which equals
1.0301289629 = 1 + rate
Therefore, rate = .0301289629 and we multiply by 100 to make a percentage:
3.01289629 %

Step-by-step explanation:
Answer:
c) 56 m²
Step-by-step explanation:
Area of the figure = area of triangle + area of rectangle
Rectangle:
length = 8 m
Width = 5 m
Area = length * width
= 8 *5
= 40 m²
Triangle:
base (b)= 4 m
height (h) = 8 m
![Area=\frac{1}{2}bh\\\\ =\frac{1}{2}*4*8\\](https://tex.z-dn.net/?f=Area%3D%5Cfrac%7B1%7D%7B2%7Dbh%5C%5C%5C%5C%20%3D%5Cfrac%7B1%7D%7B2%7D%2A4%2A8%5C%5C)
= 2* 8
= 16 m²
Area of the figure = 40 + 16
= 56 m²
That’s really really hard but i’d say c

Because the number are either rising or falling
