Here is the answer to Question 13
Answer:
56.6
Step-by-step explanation:
Since BK is a bisector of ABC at B,
this implies that:
ABC = ABK + KBC
ABC = 28.3 + 28.3
ABC= 56.6
Answer:
19
Step-by-step explanation:
24 * 80% = 24*0.8 = 24* 8/10 = 24*4/5 = 96/5 = 19.2
round down becuase 0.2, or 20% of a person can not earn honor roll without suffering catastrophic organ failure.
Answer:
Mitch can give 2 candy bars to 13 friends
Step-by-step explanation:
first, since he wants 10 left over, you subtract 36-10 which is 26. Then, since he wants to give each friend 2 candy bars, you divide 26 by 2 which equals 13.
Answer:
∫ C ( y + e√x) dx + ( 2x + cosy² ) dy = 1/3
Step-by-step explanation: See Annex
Green Theorem establishes:
∫C ( Mdx + Ndy ) = ∫∫R ( δN/dx - δM/dy ) dA
Then
∫ C ( y + e√x) dx + ( 2x + cosy² ) dy
Here
M = 2x + cosy² δM/dy = 1
N = y + e√x δN/dx = 2
δN/dx - δM/dy = 2 - 1 = 1
∫∫(R) dxdy ∫∫ dxdy
Now integration limits ( see Annex)
dy is from x = y² then y = √x to y = x² and for dx
dx is from 0 to 1 then
∫ dy = y | √x ; x² ∫dy = x² - √x
And
∫₀¹ ( x² - √x ) dx = x³/3 - 2/3 √x |₀¹ = 1/3 - 0
∫ C ( y + e√x) dx + ( 2x + cosy² ) dy = 1/3
