Answer:

$(x-4)^{2}$ >0

$(x-4)^{2}$ +4>0

so the function is always positive.

Step-by-step explanation:

As $(x-4)^{2}$ always positive, because when you square numbers you will get always a positive number.

So $(x-4)^{2}$ +4>0, because the (+4) will not effect the answer as (x-4)^{2} will be positive.

Can someone plz help plz show work

Answer:

Step-by-step explanation:

In the base we have the right triangle. Use the Pythagorean theorem for to calculate the hypotenuse:

$h^2=4^2+3^2\\\\h^2=16+9\\\\h^=25\to h=\sqrt{25}\\\\h=5\ ft$

The Lateral Area is the sum of the areas of three rectangles:

$4\ ft\ \times\ 2\ ft\to A_1=(4)(2)=8\ ft^2\\\\3\ ft\ \times\ 2\ ft\to A_2=(3)(2)=6\ ft^2\\\\5\ ft\ \times\ 2\ \ft\to A_3=(5)(2)=10\ ft^2$

The Lateral Area:

$LA=A_1+A_2+A_3\to LA=8+6+10=24\ ft^2$

Find the slope and y intercept 2x+3y=1,470

oksano4ka [1.4K]

First we need to put it in slope intercept form (solve for y). Then we get tex]y= -\frac{2}{3} x+490[/tex]. So the slope is-2/3 and the y intercept is 490.

The answer is 2cm

$8 \times 10 {}^{ - 3} \times 250 = 2000 \times 10 {}^{ - 3} \\ = 2$
or:
$8 \times {10}^{ - 3} \times 250 = 0.008 \times 250 \\ = 2$

good luck
