Answer:
is that the whole math question? I need a number after the < to solve this
Since there are as many of these triangles as the polygon has sides (eight for an octagon), you have to multiply the area of this triangle by the number of sides. You will obtain the total area of the octagon: area of octagon = 8 * base * height / 2 = perimeter * apothem / 2 .
i hope this helped you :)
Answer:
False
Step-by-step explanation:
7.3/10+28=128
35/10=128
3.5=128
This is false
Answer: $ 3045.48
Step-by-step explanation:
The exponential decay equation with rate of growth r in time period t is given by :-
, where A is the initial amount
Given : The rate of decay of population every year : 15% =0.15
The initial value = $9500
Then , the exponential growth equation in time period t is given by :-
After t= 7 years
The value of the sailboat will be :-
Hence, the value of the sailboat after 7 years= $3045.48.
