Answer:
r = 1.3 meters
Step-by-step explanation:
A python curls up to touch the tip of its own tail with its nose, forming the shape of a circle.
A python curls up to touch the tip of its own tail with its nose, forming the shape of a circle.
The python is 2.6 pi (2.6π) meters long.
What is the radius r of the circle that the python forms?
Now we have: C = π d, or (with d = 2 r): C = 2 π r.
Changing that around: r = C / 2 π
So with our value of C = 2.6π meters, that gives us:
r = 2.6π/2π = 2.6/2, so r = 1.3 meters
Answer:
find k by putting -3 where there is x than -6 on g(x)
Step-by-step explanation:
g(x)=3k-2x²
-6=3k-2(-3)²
-6=3k-18
-6+18=3k
12=3k
12÷3=3k÷3
4=k
➻ In a group of 40 people, 27 can speak English and 25 can speak Spanish.
➻ The required number of people who can speak both English and Spanish .
<u>Consider</u> ,
➻ A → Set of people who speak English.
➻ B → Set of people who speak Spanish
➻ A∩B → Set of people who can speak both English and Spanish
➻ n(A∪B) = n(A) + n (B) - n(A∩B)
➻ 40 = 27 + 25 - n (A∩B)
➻ 40 = 52 - n (A∩B)
➻ n (A∩B) = 52 - 40
➻ ∴ n (A∩B) = 12
∴ Required Number of persons who can speak both English and Spanish are <u>12 .</u>
━━━━━━━━━━━━━━━━━━━━━━
➻ n(A∪B) = n(A) + n (B) - n(A∩B)
➻ 40 = 27 + 25 - 12
➻ 40 = 52 - 12
➻ 40 = 40
➻ ∴ L.H.S = R.H.S

Answer:
EasY
Step-by-step explanation:
Okay so basically like terms are when the variable are the same
so like 5n can go with ones with the same variable which is n
so 5n as a like term would be 7n it couldn't be like 8r because it isn't the same variable as 5n
does this help?
