Answer:

1200

Step-by-step explanation:

$(6.4 *103) + (5.2 * 104)$

$6.4*103=659.2$

$5.2*104=540.8$

$659.2 + 540.8$

$=1200$

$(6.4 *103) + (5.2 * 104) = 1200$

What is the product of (2x-1)(x+4)

Novay_Z [31]

Answer:

$\large\boxed{(2x-1)(x+4)=2x^2+7x-4}$

Step-by-step explanation:

$(2x-1)(x+4)\qquad\text{use FOIL:}\ (a+b)(c+d)=ac+ad+bc+bd\\\\=(2x)(x)+(2x)(4)+(-1)(x)+(-1)(4)\\\\=2x^2+8x-x-4\qquad\text{combine like terms}\\\\=2x^2+(8x-x)-4\\\\=2x^2+7x-4$

The vertex of the parabola below is at the point (3,2) and the point (4,6) is on the parabola. What is the equation of the parab

nata0808 [166]

Answer:

$\large\boxed{y=4(x-3)^2+2\ \bold{vertex\ form}}\\\boxed{y=4x^2-24x+38\ \bold{standard\ form}}$

Step-by-step explanation:

The vertex form of a parabola:

$y=a(x-h)^2+k$

(h, k) - vertex

We have the vertex at (3, 2) → h = 3 and k = 2.

Substitute:

$y=a(x-3)^2+2$

The point (4, 6) is on athe parabola. Put the coordinates of this point to the equation:

$6=a(4-3)^2+2$ subtract 2 from both sides

$6-2=a(1)^2+2-2$

$4=a\to a=4$

Finally:

$y=4(x-3)^2+2$ vertex form

use (a - b)² = a² - 2ab + b²

$y=4(x^2-6x+9)+2$ use the distributive property

$y=4x^2-24x+36+2$

$y=4x^2-24x+38$ standard form
