Find the area of the region enclosed by x(t)=t^2-2t, y(t)=sqrt(t), and the y-axis. ...?
zaharov [31]
First find the the value of t where the curve intersects the Y-axis. This is when x = 0. 

x = t^2 - 2t = 0 = t(t - 2) 


So t= 0 and t = 2 

dA = (0 - x)*dy .... Since the curve has negative x in this region 

y = SQRT(t) and dy = [(1/2)/SQRT(t)]dt 

dA = [2t - t^2][(1/2)/SQRT(t)]dt 

dA = [t^(1/2) - (1/2)t^(3/2)]dt 


Integrate to get: A = (2/3)t^(3/2) - (1/5)t^(5/2) 


Now evaluate from t= 0 to t = 2. 


Area = [(2/3)2^(3/2) - (1/5)2^(5/2)] - [0] 
<span>
Area = SQRT(2)[4/3 - 4/5] 
</span><span>
Area = SQRT(2)[8/15) = 0.754

I need help on question 1 of symbolic representation
monitta

Answer:

f(x) = 0x + 5

Step-by-step explanation:

Lets use the slope formula to determine the slope of this graph:

m=\frac{y_{2}-y_{1}  }{x_{2}-x_{1} } \\\\m=\frac{5-5 }{4-(-7)} \\\\m=0

SO we know the slope is zero.

If we know the slope is zero, then the y intercept must be at 5.

So the equation would be:

f(x) = 0x + 5
