Answer:
65
Step-by-step explanation:
The slant height of a cone is the length of a segment from the base to the vertext along the surface of the cone.
You can use the given dimenstions as the legs of a right triangle, and the slant heifght is rthe hyopotenuse.
L^2 = r^2 + h^2
L^2 = 5^2 + 12^2
L^2 = 169
L = 13
The slant heiht is 13 cm.
LA = (pi)rL
LA = (pi)(5 cm)(13 cm)
LA = 65(pi) cm^2

6k + 10.5 = 3k + 12
Answers
Answer: 0.5
Step-by-step explanation:
The given equation:
To solve the above equation for k , we first subtract 3k from both the sides , we get
Subtract 10.5 from both sides
Divide 3 on both the sides , we get
Hence, solution to the linear equation : k = 0.5
-10.5 -10.5
6k=3k+1.5
-3k -3k
3k=1.5

2 sinx cosx - 1 + 2 sin2x
2 sin x cos2x - 1 + 2 sin2x
2 sin x cos2x - sin x + 1 - 2 sin2x
2 sin x cos2x - 1 - 2 sin2x
Answers
sin 2x = 2 sin(x) cos(x)
cos 2x = cos²x - sin²x = 2cos²x - 1 = 1 - 2sin²x
Therefore
sin 2x - cos 2x
= 2 sin(x) cos(x) - (1 - 2sin²x)
= 2 sin(x) cos(x) - 1 + 2sin²x
Answer: 2 sin(x) cos(x) - 1 + 2 sin²x

As evident from above sample space,the probability of finding exactly one Head 2\4 I.E 1\2
so the answer is B
Option B. is correct.
What is probability?
Possible chances of occurring an event are known as the probability of that event.
Sample space for tossing two coins is :
( {H,H} , {H,T} , {T,T} , {T,H} )
Formula used:
Probability of an event =
Exactly one head appeared 2 times i.e., {H,T} or {T,H}
Thus, Favourable outcomes = 2
Total outcomes = 4
P (Exactly one head) =
