Answer:

P_{R'J'M'}=36\ un.\\ \\A_{R'J'M'}=54\ un^2.

Step-by-step explanation:

Given:

A_{RJM}=6\ un^2.\\ \\P_{RJM}=12\ un.

If the triangle is dilated by a scale factor of k=3 centered at the origin, then

P_{R'J'M'}=k\cdot P_{RJM}=3\cdot 12=36\ un.\\ \\A_{R'J'M'}=k^2\cdot A_{RJM}=3^2\cdot 6=9\cdot 6=54\ un^2.

Answer:

x must equal 0 or - 10

and y must equal 1 or 6

so its 3 x 0 = 0 plus 6 x 1 = 6

or 3 x -10 = -30 plus 6 x 6 = 36 so -30 plus 36 is 6

Remark
This question likely should be done before the other one. What you are trying to do is give C a value. So you need to remember that C is always part of an indefinite integral.

y = \int (cos(x) + sin(x) ) \, dx = \int{cos(x) \,dx + \int sin(x) \,dx
y = sin(x)  -  cos(x) + C 
y(π) = sin(π) - cos(π) + C = 0
y(π) = 0  -(-1) + C = 0
y(π) = 1 + C = 0
C = - 1

y = sin(x) - cos(x) - 1  <<<<< Answer

Problem Two
Remember that y =  \int\ { \frac{1}{x} } \, dx = ln(|x|) + C
y( - e^3 ) = ln(|x|) + C = 0
y(-e^3) = ln(|-e^3|) + C = 0
y(-e^3) = 3 + C  = 0
3 + C = 0
C = - 3

y = ln(|x|) - 3  <<<< Answer
