Answer:
Option A
6.56 x 10
Step-by-step explanation:
To solve this problem we will apply the laws of indices.
One of the law states that when you are multiplying powers which have the same base, you are expected to add the powers together.
This means our answer will be
if we multiply 4.1 by 1.6, we will get 6.56.
If we subtract 3 -2 we will get 1.
Therefore our answer will be Option A
Answer:
x = {-1/5, 1}
Step-by-step explanation:
(5x - 2)² - 1 = 8
Add 1 to both sides
(5x - 2)² = 9
Take the square root of both sides
5x - 2 = ±3
------------------------------
<u>Solution I</u> for 5x - 2 = +3
5x - 2 = 3
add 2 to both sides
5x = 5
Divide both sides by 5
x = 1
------------------------------
<u>Solution II</u> for 5x - 2 = -3
5x - 2 = -3
add 2 to both sides
5x = -1
Divide both sides by 5
x = -1/5
-------------------------------
x = {-1/5, 1}
<span>If water and oil are combined in a container, the resulting liquid is a suspension. Water and oil do not mix. They form a heterogeneous mixture (a mixture whose composition is not uniform). The kind of heterogeous mixture that water and oil form is a suspension because the two lquids separate and can be easily distinguished. An emulsion, is an heterogenous mixture where small drops of one of the liquids disperse into the other liquid, so they form a stable mixture that will not separate quickly. Mayonaisse is an example of emulsion, because it consists of two liquids (oil an eggs) dispersed one into the other. Milk is also a emulsion of fat and water. So the specif term for the liquid resulting from water and liquid combined in a container is the option A. suspension.</span>
