Is the difference of 1.48-0.25 less or greater than one

What is the factored term form of 2x^3+4x^2-x

Westkost [7]

Answer: $x(2x^2+4x-1)$

Step-by-step explanation:

2x³+4x²-x, first find the Greatest Common Factor (GCF), which is x. To find the GCF, look at what all the numbers have in common, and then see if it has the greatest value. Next factor out the GCF.

$x(\frac{2x^3}{x} + \frac{4x^2}{x}-\frac{x}{x} )$ Simplify each term in the parentheses.

$x(2x^2+4x-1)$

Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! :-)

a) Suppose f"(z) exists on an interval I and f(s) has a zero at three distinct points a < b< c on I. Show there is a pbint

Fynjy0 [20]

Answer:

We can find a root in the average point (a+b+c)/3

Step-By-Step Explanation:

We can use the Rolle Theorem. Since f is two times deribable on both [a,b] and [b,c], then there exists points x in (a,b) and y in (b,c) such that f'(x) = f'(y) = 0. Now, again by using Rolle Theorem, since f' is derivable in [x,y] (because it is a closed interval in I), then there exists s in [x,y] such that f''(s) = 0. This proves a.

The cube (x-a)(x-b)(x-c) has 3 roots, a, b and c and it is two times derivable because it is a polynomial. Hence we can use (a) to ensure that there is a root on I. Nevertheless, we can try to find the root manually:

f'(x) = (x-b)(x-c)+(x-a)(x-c)+(x-a)(x-b)

f''(x) = (x-c)+(x-b)+(x-c)+(x-a)+(x-b)+(x-a) = 2(x-a)+2(x-b)+2(x-c) = 2( (x-a) + (x-b) + (x-c) ) = 6x - 2 (a+b+c).

We want x such that

6x - 2(a+b+c) = 0, or, equivalently,

3x - (a+b+c) = 0

Hence

x = (a+b+c)/3

Is a root of f'' in I.

Which function has a range of y < 3? y = 3 (2) Superscript x y = 3 (3) Superscript x y = negative (2) Superscript x Baseline

marusya05 [52]

Answer:

y = negative (2) Superscript x Baseline + 3

Step-by-step explanation:

An exponential function has a range of y > 0. In order for it to have a range of y < 3, it must be reflected across the x-axis (given a negative multiplier) and must be translated upward 3 units.

That is, for some exponential function y = b^x, you must have something of the form ...

y = -a·b^x +3

Only one answer choice has this form:

$\boxed{y=-2^x+3}$

Lewis walked 8 ··10 of a mile. Todd walked 3 ··4 of the way with Lewis. How many miles did Todd walk with Lewis? Show your work.

MrMuchimi

Complete question :

Lewis walked 8/10 of a mile. Todd walked 3/4 of the way with Lewis. How many miles did Todd walk with Lewis? Show your work.

Answer:

0.6 miles

Step-by-step explanation:

Miles walked by Lewis = 8/10 miles

Miles Todd walked with Lewis = 3/4 of the way

This means : Multiplying the fraction Lewis walked with the fraction Todd walked with Lewis

8/10 * 3/4 = 24/40 = 0.6 miles

Hence, Todd walked 0.6 miles with Lewis
