Answer:
Hello! c = 78
72 × 72 = 5184 30 × 30 = 900
5184 + 900 = 6084
78 × 78 = 6084 therefore the correct answer is 78
Hope that helps!

Step-by-step explanation:
Answer:
Step-by-step explanation:
x+90+90+78=360(sum of 4 angles is always 360 degree)
x+258=360
x=360-258
x=102
Given:
The geometric sequence is
To find:
The explicit formula for the given geometric sequence.
Solution:
We have, a geometric sequence
Here,
First term :
Common ratio :
The explicit formula of a geometric sequence is
where, a is first term and r is common ratio.
Putting and r=3, we get
Therefore, the correct option is c.
Choice 1. He did not square 40, he just multiplied by 2.
Step-by-step explanation:
Step 1:
According to the Pythagorean theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides.
The hypotenuse measures c cm while the other sides are 40 cm and 9 cm each.
Step 2:
According to the Pythagorean theorem,
This is the correct solution to the given problem. Hans did not square 40, he just multiplied by 2. Which is the first option.
