Answer:
Step-by-step explanation:
6root = 6^2= 6 x 6
= 36
6root7 = 36 x 7 = 252
Also,
5xroot7 = 5 x 7^7
= 5 x 49
= 245
Therefore,
6root7 - 5xroot7 - Xroot7 = 0
252 - 245 - 7x^2
= 7- 7x^2
One way to test if a graph is a function or not is by doing a <u>vertical line test</u>.
<em>The </em><u><em>vertical line test</em></u><em> is tested by testing if any vertical line is drawn would intersect the curve more than once. If there is any such line, the graph does not represent a function, if there isn't any such line, the graph is a function.</em>
Hope that helps!
Answer:
<em>Farmer Bill sold 120 lb of potatoes</em>
Step-by-step explanation:
Suppose farmer Bill had x lb of potatoes. He sold a quarter to the first person. A quarter is written as (1/4)x. After that, Bill had x-(1/4)x = (3/4)x.
Then he sold 4/9 of what was left to the second person, thus it was left 1-4/9=5/9 of the remaining potatoes. Multiplying both factors:

This is the remaining portion of the potatoes.
Finally, he sold 4/5 of it and the last 10 lb. This means 1 - 4/5 = 1/5 of the remaining is equivalent to 10 lb:

Thus:

x = 120 lb
Farmer Bill sold 120 lb of potatoes
Answer:
B
Step-by-step explanation:
(x⁴ + x)^½
As x approaches infinity, x⁴ becomes much larger than x. So:
(x⁴ + x)^½ ≈ (x⁴)^½ = x²
So x² grows at the same rate as (x⁴ + x)^½.
