sin α = opposite leg/ hypotenuse
For ΔABC,
sin A = |BC|/|AB|
sin A = 12/37
Answer:
6/7
Step-by-step explanation:
i watched a video
Answer:
28
Step-by-step explanation:
2x + 3y = 7
Now, since 8/2 is 4 and 12/3 is also 4, we can multiply the entire original equation by four in order to get the equation that we want
4(2x + 3y = 7)
8x + 12y = 28
we are given
piecewise function as
f(x) =5 when x<=-2
f(x)=ax+b when -2<x<3
f(x)=-5 when x>=3
We are given f(x) is continuous for all values of x
so, it will also be continuous at x=-2 and x=3
Continuity at x=-2:
Value of both functions must be same at x=-2
so, we get
Continuity at x=3:
Value of both functions must be same at x=3
so, we get
so, we get system of equation as
now, we can subtract both equations
and we get
now, we can find b
so, we get
