Answer:
390
Step-by-step explanation:
5 or more, means round up.
So 385 ( 5 or above ) - round to the nearest tenths place...
= 390
Answer:
390
Step-by-step explanation:
The number in the tenth place is 80 so you look on the right, the number is 5. If the number is 5 or above, that means you go up. SO it's 390

Use the remainder theorem to determine if x=6 is a zero of the following polynomial, and find the quotient and the remainder.
p(x)=x^4+4x^3-66x^2+45x-54
A. No, x=6 is not a zero of the polynomial.
The quotient is x^3-2x^2-54x+369, and the remainder is -2,268.
B. Yes, x=6 is a zero of the polynomial.
The quotient is x^3-2x^2-54x+369, and the remainder is 0.
C. Yes, x=6 is a zero of the polynomial.
The quotient is x^3+10x^2-6x+9, and the remainder is 0.
D. No, x=6 is not a zero of the polynomial.
The quotient is x^3+10x^2-6x+9, and the remainder is 0.

When does an equation involving rational expressions have straneous root
Answer:
Many mathematical operations are reversible, meaning you can go not just from A to B, but by the same reason go from B back to A.
Example x + 4 = 7. Subtract 4 from each side to get x = 7 - 4 = 3. But you could, if you wished, go from x = 3 to x + 4 = 7 by simply doing the opposite, adding 4.
Now consider an operation that is NOT reversible.
Example: Given sqrt(x) = x - 2. Square each side to get x = (x - 2)^2 =x^2 - 4x + 4, or
x^2 - 5x + 4 = 0. Factoring gives (x - 1) (x - 4) = 0. So, IF the original equation holds for a real number x, then the only possibilities are x = 1, x = 4.
If you plug x = 4 back into original equation, you get sqrt(4) = 4 - 2, which is true. But, if you plug in x = 1, you get sqrt(1) = 1 - 2, which is NOT true, as sqrt(1) = 1, not -1. The logic of the derivation was that, IF original equation were true, then x could possibly be only 1 and/or 4. In effect, it was really telling you what x is NOT, namely any number besides 1 and 4. Once you test the two “candidates” you see that one works and the other doesn’t.
Why does this happen? It has to do with the fact that square root is only a principal branch. Just as sqrt(16) is only 4 and not -4, so we are dealing with a limited possibility with which to start. Squaring glosses over this, and when you solve a quadratic equation, it generally gives two solutions (not nec. real). Because sqrt(x) started out to be nonnegative, that created the problem at end.

Determine whether the relation is a function. Explain pls
Answer:
The given relation is not a function.
Step-by-step explanation:
A relation is any set of ordered pairs, which can be thought of as (input, output).
A function is a relation in which no two ordered pairs have the same first component (x-values or input) and different second components (y-values or output).
Given the following relation: {(7, 4), (5, - 1), (3, - 8), (1, - 5), (3, 6)}
There is an input value (x = 3) that has two corresponding outputs (y-values): y = -8 and y = 6.
Remember that a function can only take on one output for each input.
It also helps to do the Vertical Line Test, which allows us to know whether or not a graph is actually a function. If a vertical line intersects the graph in all places at exactly one point, then the relation is a function. To use the vertical-line test, imagine dragging a ruler held vertically across the graph from left to right. If the graph is that of a function, the edge of the ruler would hit the graph only once for every x -value.
Attached is a screenshot of the plotted points on a graph, where I performed the Vertical Line Test. The green line is the vertical line that contains two points that made the relation invalid as a function.

Answer:
[tex]\frac{2}{5}[/tex] and [tex]\frac{2}{7}[/tex]
Step-by-step explanation:
We want to work backwards. Currently we have [tex]\frac{ }{ }[/tex][tex]\frac{?}{?}[/tex] ÷ 5 = [tex]\frac{2}{25}[/tex].
If we multiply both sides by 5, we get [tex]\frac{?}{?}[/tex] = [tex]\frac{2}{25}[/tex] × [tex]\frac{5}{1}[/tex].
We can use multiplication of fractions to solve this. To multiply fractions we multiply the two numerators together and multiply the two denominators together, giving an answer of [tex]\frac{?}{?}[/tex] = [tex]\frac{10}{25}[/tex].
This can be simplified to [tex]\frac{2}{5}[/tex].
We can use the same method on the other equation to get an answer of [tex]\frac{2}{7}[/tex].

Given any right triangle, the sum of the areas of the squares formed by the legs is equal to the area of the hypotenuse. This is referred to as the:
Question 5 options:
A) pythagorean theorem
B) perimeter
C) surface area
D) area
Explanation:
You are probably familiar with the formula [tex]a^2+b^2 = c^2[/tex] which is the pythagorean theorem.
The [tex]a^2[/tex] is the square of the first leg 'a', while [tex]b^2[/tex] is the square of the second leg b. Adding those two squares leads to the square of the hypotenuse c, aka [tex]c^2[/tex]. This only works with right triangles, which are triangles that have a 90 degree angle.
