Answer:
The value of k=1
So, Maura claim is incorrect. The value of k=1 and not k=1/2
Step-by-step explanation:
We need to determine the value of k if 
We are given:

Exponent rule, if bases are equal the exponents are equal
We can write 

Now since the base is same, i,e 2 so, the exponents will be same

So, the value of k=1
So, Maura claim is incorrect. The value of k=1 and not k=1/2
The answer is -3. Adding a negative onto a positive is just like subtracting from the positive. So, first off, 5+(-3) is 2. Then, subtracting 6 from the 2 will give you a negative number, -4. Subtracting a negative changes the sign to be a plus, so you plus one onto the -4. This leaves you with the answer of -3.
Consider triangle XYZ with vertices at points X(1,-3), Y(3,0) and Z(-1,-1). If triangle XYZ is reflected across the line y = 1, then the rule of reflection is
(x,y)→(x,-y+2).
The image X' of point X will have coordinates according to the given rule:
X(1,-3)→X'(1, -(-3)+2)=X'(1,5).
Answer: correct choice is D.
The answer is D.
The formula for the volume of a sphere is
You would divide the diameter in half which would give you your radius (r).
Then you plug in the radius value to find the volume of ONE ball.
You would then multiply by 10 to find the volume of TEN golf balls.
D is the closest answer to the volume of ten golf balls
