Answer:
x = ¾-a
Step-by-step explanation:
x + a = ¾
Subtract a from each side
x + a -a= ¾-a
x = ¾-a
Answer:
The common ratio of the geometric sequence is:
Step-by-step explanation:
A geometric sequence has a constant ratio 'r' and is defined by
where
Given the sequence
Compute the ratios of all the adjacent terms:
The ratio of all the adjacent terms is the same and equal to
Therefore, the common ratio of the geometric sequence is:
Answer:
129.99
Step-by-step explanation:
First, we have to solve the sides of the right triangle by using the Pythagorean theorem: a² + b² = c² where c is the length of the hypotenuse. Then, we can use the legs as length and height of the triangle and find the area by 1/2(base x height).
x² + 60² = 68²
x² + 3600 = 4624
x² = 1024
x = √1024
x = 32 = length of the other side
A = (1/2)(32) (60) = 960 mm²
