Answer:
v = 17.4 meters
Step-by-step explanation:
This is a triangle with height (red dotted line) given.
The area of a triangle is given by the formula:
Where
A is the area
b is the base length
h is the height
Given height = 12, and
area = 104.4
THe base is labeled as "v", so we find v by replacing into formula:
The base, v, is 17.4 meters
Answer:
log 4
--------- that's the answer yw
9
Step-by-step explanation:
Answer:
19 feet
Step-by-step explanation:
Area= length × length
361= l²
√361= l
19= l
Answer:
Sn = -9(1-(-3)^n)/4
Step-by-step explanation:
Since r < 1, the sum of nth term of a geometric sequence is expressed as;
Sn = a(1-r^n)/1-r
a is the first term
n is the number f terms
r is the common ratio
An = -9(1-(-3)^n)/1-(-3)
Sn = -9(1-(-3)^n)/4
Hence the sum of the nth term of the series is Sn = -9(1-(-3)^n)/4
