Answer:

2.5 x 10^-27

Step-by-step explanation:

(2 x 10^13)^-2

= (2^-2) x (10^13) ^-2

= 0.25 x 10^-26

= 2.5 x 10^-27

Assume that when you take a bath, you fill a tub to the halfway point. The tub measures 6 feet by 3 feet by 2.6 feet.
masya89 [10]

Using the volumes, it is found that you spend more water taking a bath.

<h3>What is the volume of a rectangular prism?</h3>

The volume of a rectangular prism of length l, width w and height h is given by:

V = lwh.

For this problem, the dimensions of the tub are as follows:

l = 6, w = 3, h = 2.6.

You use half of that, hence:

V = 0.5 x 6 x 3 x 2.6 = 23.4 feet³.

For the bath, the number of cubic feet is:

1.42 x 11/7.5 = 2.08 feet³.

Hence you spend more water taking a bath, as 23.4 > 2.08.

Find the perimeter of an equilateral triangle that has a side measure of<br> 45 cm.
Sav [38]

A triangle with 45 cm of perimeter has 15 cm of side. The

"altitude" connects the middle of one side to the opposite vertice. This forms a rectangle triangle with hypothenuse 15 cm and the small catet a= 7.5 cm. So by the Pythagoras theorem we must solve the equation:

7.5^2+b^2=15^2

b=sqrt(225-56.25)=sqrt(168.75)=12.99 cm

Other solution was using trigonometry:

b/(side)= sin(pi/3)=sqrt(3)/2

b=7.5*sqrt(3)/2=12.99 cm

If i= square root of -1, what is the value of i 3?
Furkat [3]
If  i = √-1 ,

then ...

i²  =  (√-1)²  =  -1

i³  =  - √-1  =  -i          <== the answer to the question

i⁴  =  (i²) · (i²)  =  (-1) · (-1)  =  1

and then the whole thing starts over again, for higher powers of  i .
