Answer:

A. x^2 + 3x + 2

D. 3x^4 + 4x^3 - 3x^2 - 1

E. 3t^3 + 3t^2 + 2t

Step-by-step explanation:

Standard form is where the equation is set up so that the exponents decrease from left to right, and where you put a number with no variable or exponent last.

Answer:

option A, D and E

Step-by-step explanation:

The polynomial is in standard form only when the exponents starts with largest exponent and keeps on decreasing from greatest to least

$x^2+3x+2$ has largest exponent 2 and then x

option B and C has exponents that are not in order.

$3x^4+4x^3-3x^2-1$ has largest exponent 4 and the exponents are from greatest to least.

$3t^3+3t^3+2t$ has largest exponent 4 and the exponents are from greatest to least.

last option has exponents that are not in order.

If the value of x increases by 4 ,how does the value of m(x-5) change

seraphim [82]

I'm going to assume that you're discussing the linear function y = mx + b. If that's not it, please provide more information on the function you're studying.

y = mx + b has a graph that is the straight line through (0,b) with slope m.

y = m(x-5) + b has a graph which is parallel to the previous graph, but intersects the x-axis at a different point.

Examples: start with y = mx + b
Suppose we have y = 3x + 2 to work with
The graph intersects the y-axis at (0,2). It intersects the x-axis where y=0=3x+2, or at x = -2/3 => (-2/3, 0)

Now modify y = 3x + 2 by replacing "x" with "x-5." the graph of this "new" function f(x) = 3(x-5) + 2 is parallel to the original graph, but lies 5 units to the right of the original graph. Both lines have slope 3.

In this case, if x increases by 4 (as your problem states), y will increase by 3(4), or 12, units.

If we go back to y = m(x-5), we see that the graph of this function intersects the x-axis at x=5, and this graph has the (unknown) slope m.

If x increases by 4, y increases by (m)(4), or 4m.

Can a vector have nonzero magnitude if a component is zero? if no, why not? if yes, give an example.

dangina [55]

Can a vector have nonzero magnitude if a component is zero?

Yes, a vector can have zero components along a line and still have a non-zero magnitude.

Example: Consider a two dimensional vector 2i + 0j. This vector has zero components along a line lying along the Y - axis and a non- zero component along the X - axis. The magnitude of the vector is also non - zero.

Now, magnitude of 2i + 0j = $\sqrt2^2+\sqrt0^2$ =2
