Answer:

472800

= 4.728 × 10⁵

Step-by-step explanation:

(4.7 × 10⁵) + (2.8 × 10³)

4.7 × 10⁵ + 2.8 × 10³

(4.7 × 10²+ 2.8) × 10³

(4.7 × 100 + 2.8) × 1000

(470 + 2.8) × 1000

472.8 × 1000

= 472800

= 4.728 × 10⁵

Answer:

472800 or 4.728x10^5

Step-by-step explanation:

first you would slove (4.7x10^5) and (2.8x 10^3). Which would be 470000 and 2800. Then add the two together to get 472800. And if they want you to put it back into scientific notation then it would be 4.728x10^5

Ahh yes, negative exponents always give us a scare once and a while. All the negative means is to flip the position of its base. For instance, if x has a negative exponent and x in the denominator, all you would have to do is move x to the numerator with the same power (except it's no longer negative). Before we substitute x and all the other variables which the values given, let's eliminate the negatives first.

After flipping positions/eliminating the negative exponents it should look like this:

\frac{ 2^{2} x^{3} }{ y^{5} }
which simplifies to 
\frac{ 4 x^{3} }{ y^{5} }
now that everything is simplified, and all negative exponents are eliminated we can substitute x with 2, and y with (-4).
\frac{4 (2)^{3} }{ (-4)^{5} }
which simplifies to 
\frac{4(8)}{(-1024)} = \frac{32}{-1024} = - \frac{1}{32}

Final Answer: - \frac{1}{32} [/tex]

What is the difference between cross-section and intersection in geometry?
Triss [41]
A cross-section is the shape that would be exposed when cutting straight through a 3-D object. for example, cutting horizontally through a regular cone would expose a circle.

an intersection is where 2 or more shapes (does not matter how many dimensions) overlap. for example, the point at which two lines overlap is the intersection. or the area that two overlapping circles share is the intersection.

lianna [129]

Answer:

The answer is (x-9) (x-3).

Step-by-step explanation:

This is because when you multiply them together you get

x^{2}, -9x, -3x, and 27

When you add the like terms you get,

x^{2} - 12x +27

Between which two square roots of integers could you find π
LUCKY_DIMON [66]
Hello.

Since 3 < pi < 4, 
√9 < pi √16 

In fact, since pi^2 = 9.86, 

<span>√9 < pi < √10. 

Which means the you</span><span> can find pi between square roots √9 and √10.
