Answer:
1.5<3-sqrt(2)<1.6
Step-by-step explanation:
Just do 3-1.4 and 3-1.5 and put the precise answer in the middle.
Hello from MrBillDoesMath!
Answer:
Choice B.
Discussion:
From the first step
324 x^6 y^ 8 =
2^2 * 3^4 * x^2 * x^4* y^8
so the fourth root of this is
2 ^(2/4)* 3^(4/4) x^(2/4)* x^(4/4)*y^(8/4) =
2^ (1/2) * 3^1 * x^(1/2) * x^(1)* y^ (2) =
(2x)^(1/2) * 3 * x * y^2 =
3 * x * y^2 * sqrt(2x) =
3 * x * y^2 * ( (2x)^2) ^ (1/4)) =
3 * x * y^2 * (4x^2) ^ (1/4)
which is choice B
Thank you,

Answer: It is a function
Why? Because it is impossible to draw a vertical line through more than one point on the red graph. Any vertical line will only pass through exactly one point on the red graph.
Put another way: any input x leads to exactly one and only one output y. If it was possible to have some input lead to multiple outputs, then it would be possible to draw a vertical line through more than one point on the red graph. The graph is said to "pass the vertical line test" proving it is a function.
note the closed circle at (0,2) and the open hole 2 units above that. If the open hole was filled in, then this is where the graph would fail the vertical line test; however, the open hole helps this piecewise graph be a function.
Let f=number of flowers in a vase, then:
5f-16=24 add 16 to both sides
5f=40 divide both sides by 5
f=8
So there were 8 flowers per vase in the beginning.
Equivalent fraction for four this is 8/10
