Answer:
C) {(3, 4), (3, 5)}
Step-by-step explanation:
We know that,
<em>'Function is a relation in which every element of the domain is mapped to a unique element in the co-domain'.</em>
So, we get that,
<em>In the ordered pair (x,y), the if 'x' is mapped to two values say y and z, then for the relation to be a function, y must be equal to z.</em>
So, according to the options, we see that,
In option C i.e. the relation {(3,4), (3.5)}, we have that, 3 does not have unique image i.e. it is mapped to 4 and 5 both.
Thus, this relation does not satisfy the definition of a function.
So, option C will not represent a function.
Answer:
B. ITS FIRST TERM IS A PERFECT SQUARED ITS MIDDLE TERM IS ALWAYS NEGATIVE.
Answer:
CA = 5
Step-by-step explanation:
Since the sides are 3 and 4, we recognize this as a 3:4:5 right triangle, with CA = 5. Using the Pythagorean theorem confirms this:
CA² = AB² +BC²
CA² = 3² +4² = 9 +16 = 25
CA = √25
CA = 5
He / she didn’t drop down the 2 after subtracting 19 from 242, instead he / she dropped down a 0.
1. Two triangles can be mapped to each other only if they are similar.
2. So we are assuming similarity of the triangles.
3. First we translate vertex A to vertex X
Second, we rotate AC to XZ (or now AZ) , with an angle measure equal to that of angle CXZ
third we dilute the larger to the smaller so that they match.
