The area of the triangle is 90 m²
Explanation:
Given that the base of the triangle is 15 m
The altitude of the triangle is 12 m
<u>Area of the triangle:</u>
The area of the triangle can be determined using the formula,
where b is the base and h is the altitude
Thus, we have,
and 
Substituting the values in the above formula, we get,
Multiplying the terms, we get,
Dividing, we get,
Therefore, the area of the triangle is 90 m²
rules to find :- 1 All non zeroes number are significant
2 if zero proceeding the decimal point also work as non zero figure
3 zero are following the decimal point and proceeding the first non zero digit
4 Zero in between 2 non zero digits are also significant
5 if 1 zero follow the decimal point
790 :- 2 significant figures
0.0391 :- 3 significant figures ( follow 3 rule)
81.05 :- 4 significant figures ( rule 4)
0.000001 :- 1 significant figure
8546 :- 4 significant figures
79.0 :- 3 significant ( rule 5)
Answer:
7
Step-by-step explanation:
Answer:
First 3 are functions . Last one is not a function
Step-by-step explanation:
They are all functions except the last one.
The last one is not a function because it has duplicate x- values in the ordered pairs (1, -1) and (1, -6). There are 2 outputs for one input so its a relation but not a function
