Find the product .-2 [7 -4 0]

1 answer:

4 0

It says find the product, so that means multiplication
-2[7 -4 0] = [-14 8 0] solving: [-14 8 0] [-3 0 5]
[42+0+70 -24+0+40 0+0+0]
[-14 8 0] * [-3 0 5] = [112 0 -30] = [112 16 0]
[112 16 0]*[6 2 1]
[112 0 -30]* [6 2 1] = [1008 114 0] [672+224+112 96+32+16 +0]
=[1008 114 0].

What is the following simplified product? Assume x greater-than-or-equal-to 0 2 StartRoot 8 x cubed EndRoot (3 StartRoot 10 x Su

RideAnS [48]

This is the simplest form $4\sqrt{5}x^3(6\sqrt{x} -\sqrt{2})$ .

<h2>Exponent</h2>

Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. X is the base and n is the power.

<h3>Simplification</h3>

Simplification is to make something easier to do or understand and to make something less complicated.

Given

$\rm 2\sqrt{8x^3} * (3\sqrt{10x^4} - x\sqrt{5x^2} )$ is an expression.

<h3>How to make it simple?</h3>

$\rm 2\sqrt{8x^3} * (3\sqrt{10x^4} - x\sqrt{5x^2} )$

On simplifying, we have

$\rm 4\sqrt{2} (x)^{\frac{3}{2}} * ( 3\sqrt{10} x^2 - \sqrt{5} x^{\frac{3}{2}})\\\\24\sqrt{5} x^{\frac{7}{2}} - 4\sqrt{10}x^3\\\\4\sqrt{5}x^3(6\sqrt{x} -\sqrt{2} )\\$

This is the simplest form $4\sqrt{5}x^3(6\sqrt{x} -\sqrt{2})$ .

Help I need this rn!<br> And please explain

slamgirl [31]

Answer:

(4, 0)

Step-by-step explanation:

The circumference of a circle is $2 \pi r$ where <em>r</em> is the radius.

In this case, $2 \pi r = 10 \pi$ . Divide both sides of the equation by $2\pi$ to get

$r=5$

The center of the circle is on the <em>x</em>-axis, so the intercepts are 5 units to the left of the center and 5 units to the right of the center. The two intercepts are (-1-5, 0) and (-1+5, 0). The point that is on the positive <em>x</em>-axis is (4, 0).

In a 30-60-90 triangle the long leg is half the hypotenuse.

pentagon [3]

And because we know that we cut the base of the equilateral triangle in half, we can see that the side opposite the 30° angle (the shortest side) of each of our 30-60-90 triangles is exactly half the length of the hypotenuse.
