Answer:
(d) -1.83
Step-by-step explanation:
The explicit expression for the sum is ...
S = (-11/5)×(1 -(-1/5)^10)/(1 -(-1/5)) = -2.2(1 -1.024×10^-7)/1.2
S = -1.8333331456
The sum is approximately -1.83.

The area of the triangle is 52,000 cm².
<h3>What is the area of the triangle?
</h3>
A triangle is a three-sided polygon with three edges and three vertices. the sum of angles in a triangle is 180 degrees
Area of a triangle = 1/2 x base x height
- Base = 4 x 5 x 4² = 320
- Height = 320 + 5 = 325
Area = 1/2 x 320 x 325 = 52,000 cm²

Answer:
126 degrees
Step-by-step explanation:
Every triangle equals to 180 degrees so all you have to do is add 26+28 which equals 54 then subtract that from 180 and there's your answer.
26+28 = 54
180-54 = 126

A geometric sequence follows a pattern with a common ratio.
Find the ratio between 3 and 9
If you multiply 3 by 3 the answer would be 9.
The common ratio is 3.
Now multiply 9 by 3 to get 27.
The answer is D. 27
