Step-by-step explanation:
Given : Function 
To find : The derivative of the function by using the Product Rule ?
Solution :
The product rule of derivative is

Here, u=x-3 and v=x+3




Therefore, 
Answer: -3.0593
Step-by-step explanation:
The test statistic for the difference between two population mean (when population standard deviations
are known ) is given by :-

where ,
= Sample sizes taken from two populations 1 and 2.
= Difference between two Sample mean.
= Standard deviations of populations 1 and 2.
As per given , we have
We assume that the data follows a normal distribution.
Then, the test statistic will be :-
Hence, the test statistic= -3.0593
Answer:
(-6,1)
Step-by-step explanation:
The rule for reflecting over the X axis is to negate the value of the y-coordinate of each point, but leave the x-value the same.
The area of a square or a rectangle (which is the shape of any room in a house) is:
Area = width x length
So, in this case:
Area = 51 m x 26 m = 1326 Sq meters. Which is pretty big if you ask me.
Anyhow, Ms Melcher needs to buy 1326 sq meters
Answer:the ANS to 4 significant figures is 51.92
Step-by-step explanation:u first find the area of the whole chord which is 150 divided by 360 multiplied by the π × 7^2 subtracted from the area of The triangle by doing 1/2×7×7sin150. I hope it helps
