Answer:
Graph of Option D represents 
Step-by-step explanation:
we are given our function as
squaring on both sides we get
It represent a parabola opening towards the positive side of x axis. Hence it gives us some preliminary idea about the graph of the function we are given .
However our original function is
Domain of is all positive values of x
And square root of positive values will always result in positive values. Hence y can not be negative as the range is All positive values of y
Hence we erase the graph of below x axis to obtain the graph of
Answer:
15
Step-by-step explanation:
Width = x
Length =x+4
X(x+4)=60
X^2 +4x=60
(X+10)(x-4)
X=-10 and 4
Can’t use -10. So the answer is width =4. Length =8
Answer: Option A
Step-by-step explanation:
If we have 5 cans of ketchup they cost $ 5.25. Then the unit price of cans is what each can costs individually.
The unit price should then be less than $ 5.25, and that is the price for 5 cans and we want to know the price for just one can of ketchup.
Then to calculate the price of each can divide the price of the 5 cans by 5.
Take your base x the height, than 1/2 it. The answer would be 300.
