sin60^o= \frac{a}{2 \sqrt{2} }  \ \ \to  \ a=2 \sqrt{2} *sin60^o=2 \sqrt{2}* \frac{ \sqrt{3}}{2}= \sqrt{6}     \\  \\ cos60^o =  \frac{b}{2 \sqrt{2} }  \ \ \to  \ b=2 \sqrt{2} *cos60^o=2 \sqrt{2}*0.5= \sqrt{2}

Answer: a=√6,  b=√2

Determine the value of c so that f(x) is continuous on the entire real line when
mixer [17]

Answer:

A. -4

Step-by-step explanation:

Given the function f(x) = x + 3 for x ≤ -1 and 2x - c for x > -1, for the function to be continuous, the right hand limit of the function must be equal to its left hand limit.

For the left hand limit;

The function at the left hand occurs at x<-1

f-(x) = x+3

f-(-1) = -1+3

f-(-1) = 2

For the right hand limit, the function occurs at x>-1

f+(x) = 2x-c

f+(-1) = 2(-1)-c

f+(-1) = -2-c

For the function f(x) to be continuous on the entire real line at x = -1, then

f-(-1) = f+(-1)

On equating both sides:

2 = -2-c

Add 2 to both sides

2+2 = -2-c+2

4 =-c

Multiply both sides by minus.

-(-c) = -4

c = -4

Hence the value of c so that f(x) is continuous on the entire real line is -4
