Answer:
(-3,-10)
Step-by-step explanation:
Given part a, you seem to know the midpoint formula. We can easily edit that to figure out what an endpoint is. Say that a variable "a" represents the x coordinate of D, and b the y coordinate. As the x coordinate of M is 0.5, and the x coordinate of C is 2, we can use the midpoint formula to say that 
. Multiplying both side by 2, we get that a+2=-1, and subtracting both sides by 2, a=-3. Similarly, 
, b+7=-3, and b=-10, making our answer (-3, -10). Let me know if you have any questions.
Answer:
270
Step-by-step explanation:
Since you have the value of x as 90
3x=3*90
3x=270
Answer:
its c
Step-by-step explanation:
Answer:48 sq. Inches
Step-by-step explanation:
Integration by parts
Integral(udv)=uv-integral(duv)
In this case we will make u=x and dv=8e^(8x) so du=1 and v=e^(8x)
Now integral(8xe^(8x)) => xe^(8x) - integral(e^(8x)) => xe^(8x) - e^(8x)/8 => (e^(8x))(x-1/8)
Final answer:
(E^(8x))(x-1/8) + some constant C
Hope I helped :)
