Answer:1000cm
Step-by-step explanation:
Volume=length ×width×height
Each side is 10
10×10×10=1000
Hi there!
The range of a function describes its possible y-values. For example, y=x produces a linear graph. Its range is all real numbers, meaning that for any value of y, the function is defined.
However, for y=x², for example, the range is y>0, since there the graph doesn't travel to y-values less than 0. The function is only defined when y>0.
To find the range of the given functions, you can try graphing them. Or, if you've memorized the ranges of their parent functions, you can try to take that and apply transformations.
Answer for the first question:
f(x)=-√x
The parent function is f(x)=√x. The range of this is y≥0.
f(x)=-√x
Adding a negative in front of the square root reflects the function across the x-axis, meaning the range is therefore flipped too:
y≤0
I hope this helps!
Answer:
y + 1 - 5(x - 2)
Step-by-step explanation:
Borrow (2, -1): Substitute 2 for x and -1 for y, and -5 for m in y = mx + b:
-1 = -5(2) + b. Then b = 9, and the desired equation in point-slope form is:
y - (-1) = -5(x - 2), or
y + 1 - 5(x - 2)
Hello.
A trinomial is a perfect square if the square root of the first term times the square root of the third term times 2 equals the middle term.

Answer:
8
Step-by-step explanation:
Since the associate makes $54 every day he works, we know he makes a minimum of $54. So, from his goal of $326, we can subtract the minimum to find how many phones he must sell.
326 - 54 = 272
So, he must sell $272 worth of phones. For every phone he sells, he makes $34. So, we can find how many phones he must sell by dividing the goal by the cost of each phone.
272 / 34 = 8
So, he has to sell 8 phones, at the very least, in order to achieve his goal.
