Mathematics
1 answer:
Deffense [45]3 years ago
5 0

Answer:

3.427 *10^3

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

alina1380 [7]

Answer:  The correct option is (C) a^5.

Step-by-step explanation:  We are given to choose the correct simplification for the following expression :

P=a^2.a^3~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

We will be using the following property of exponents :

x^a.x^b=x^{a+b}.

So, the simplification of expression (i) is as follows :

P\\\\=a^2.a^3\\\\=a^{2+3}\\\\=a^5.

Thus, the correct simplification of the given expression is a^5.

Option (C) is CORRECT.

A rectangle has a width of 5 yd and a length of 9 yd.
Yuri [45]

Answer:

Option The area is increased by a factor of 16

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to scale factor squared

Let

z-----> the scale factor

x------> the area of the dilated rectangle

y------> the area of the original rectangle

z^{2}=\frac{x}{y}

we have

z=4 ------> is an enlargement

so

substitute

4^{2}=\frac{x}{y}

16=\frac{x}{y}

x=16y

therefore

The area is increased by a factor of 16
