(2x+3)*4 is less than or equal to 10. For x, the number, you would get x is greater than or equal to -1/4.

Jenna uses 18 inches of ribbion for each box she wraps how many yards of rib ion does she need to wrap 4 boxes

Sav [38]

Hello Myeisha91!

First we need to find how many inches in total to wrap 4 boxes. We do that by multiplying 18 x 4 = 72 so Jena needs 72 inches. The question wants to know how many yards so we need to convert 72 inches into yards. We can convert inches to yards by using a conversion factor. We know that 1 inch = 0.0277778 yd. Now that we know 1 inch = 0.0277778 yd, lets convert the 72 inches to yards.

We convert 72 in to yards by multiplying 72 in by $\frac{0.0277778\;yd}{1\; in}$
$72\;in\times\frac{0.0277778\; yd}{1\;in} = 2\; yd$
So Jenna will need 2 yards to wrap 4 boxes.

En las potencias con base 10, el resultado será la unidad seguida de tantos ceros como indica la cifra del exponente

radiacion

En matemáticas, la radicación es el proceso de hallar raíces de orden n de un número a.1.

De modo que se verifica que

x n = a {\displaystyle x^{n}=a}

, donde n es llamado índice u orden, a es llamado radicando, y x es una raíz enésima.23

La raíz de orden dos de

a {\displaystyle a}

, se llama raíz cuadrada de

a {\displaystyle a}

y se escribe como

a {\displaystyle {\sqrt {a}}}

o también

a 2 . {\displaystyle {\sqrt[{2}]{a}}.}

La raíz de orden tres de

a {\displaystyle a}

, se llama raíz cúbica de

a {\displaystyle a}

y se escribe como

a 3 . {\displaystyle {\sqrt[{3}]{a}}.}

Las raíces de órdenes superiores se nombran usando números ordinales, por ejemplo raíz cuarta o raíz séptima.

La radicación es la operación inversa a la potenciación. s:

Find the range of p in equation p(x+1) (x-3)=x-4p-2 has no real roots.

Tanya [424]

Answer:

$\displaystyle p > \frac{1}{4}$ .

Step-by-step explanation:

Expand the left-hand side of this equation:

$p\, (x + 1)\, (x - 3) = p\, \left(x^2 - 2\, x - 3\right) = p\, x^2 - 2\, p\, x - 3\, p$ .

Collect the terms, so that this quadratic equation is in the form $a\, x^2 + b\, x+ c = 0$ :

$p\, x^2 - 2\, p\, x - 3\, p = x - 4\, p - 2$ .

$p\, x^2 - (2\, p + 1)\, x + (p + 2) = 0$ .

In this equation:

$a = p$ .
$b = -(2\, p + 1)$ .
$c = p + 2$ .

Calculate the quadratic discriminant of this quadratic equation:

$\begin{aligned}b^2 - 4\, a\, c &= (-(2\, p + 1))^2 - 4\, p\, (p + 2) \\ &= 4\, p^2 + 4\, p + 1 - 4\, p^2- 8\, p = -4\, p + 1\end{aligned}$ .

A quadratic equation has no real root if its quadratic discriminant is less then zero. As a result, this quadratic equation will have no real root when $-4\, p + 1 < 0$ . Solve for the range of $p$ :

$\displaystyle p > \frac{1}{4}$ .
