Step-by-step explanation:
Using the rule of radicals
×
⇔
Simplifying each radical before combining them.
=
= ×
= 3

=
= ×
= 5

Hence
2(3) - 3(5
= 6 - 15
= - 9 → C
Answer with explanation:
Pre -image= Vertices of Δ R ST=R(2, 0), S(4, 0), and T(1, –3)
Image of Δ R ST after rotation= R'(0, –2), S'(0, –4), and T'(–3, –1)
Pre-Image lies in Fourth Quadrant and Image lies in Third Quadrant.
If triangle is rotated by different angles in anticlockwise direction,then
If triangle is rotated by different angles in Clockwise direction,then
⇒→So, Pre image that is ,Δ R ST having vertices ,R(2, 0), S(4, 0), and T(1, –3) when rotated by either 90° in clockwise direction or by 270°, in anticlockwise Direction to get Image Δ R' S'T' having vertices R'(0, –2), S'(0, –4), and T'(–3, –1) .
Answer:
Independent.
Step-by-step explanation:
Independent events:
Two events, A and B, are said to be independent if the probability of both happening is the same as the multiplication of the probabilities of each happening, that is:
Thus, P(A and B)=P(A)•P(B) is used when two events are independent.
