Answer:
a(7)=3645
Step-by-step explanation:
you have :
f(1) =a= 5
and from recursive rule: f(n) = r · f(n − 1) and f(n) = 3 · f(n − 1)
So r=3
then
a(n)=a*r^(n-1)
a(7)=5*3^(7-1)
a(7)=5*3^6=3645

Answer:
c
Step-by-step explanation:
because if you look at the line below it it shows 180 degrees because it is a straight line if that makes sense. if not just trust me.
If you are reffering to this dot plot, it would be 13 trees being studied.
You find the answer through the Pythagorean theorem
a^2 + b^2 = c^2 a & b are the legs and c is the hypotenuse
a = 40
b = ?
c = 41
40^2 + b^2 = 41^2
1600 + b^2 = 1681
b^2 = 1681 - 1600
b^2 = 81
b = 9
the length of the other leg is 9

Answer and step-by-step explanation:
If it is a rectangle, the formula is:
L * W
Fill in the values:
4*6.9
Then solve.
27.6
So, if it is a rectangle, the answer is (C), 27.6 Inches squared.
If it is a triangle, the the formula is:
(B*H)/2
Fill in the values:
4*6.9/2
Simplify:
27.6/2
Then solve.
13.8
So, if it is a triangle, the answer is (A), 13.8 Inches squared
Hope this helps!
