<span>The answer is B. compound.
An element is composed of only one kind of atom. You cannot separate molecule into simpler substances. For example, hydrogen (H) and oxygen (O) are elements each made of only one atom. Two or more different atoms bonded to one another are a compound. For example, 2 atoms of hydrogen (H) and 1 atom of oxygen are bonded to one another and form water. Thus, water is compound. Mixtures consist of two or more substances that are not chemically combined. Solutions and colloids are mixtures.</span>
Answer:
1/2
-1/2
Step-by-step explanation:
we know that
If a dilation produce a contraction that means that the absolute value of the scaling factor is less than 1
If a dilation produce an enlargement that means that the absolute value of the scaling factor is greater than 1
<u><em>Verify each case</em></u>
case 1) 2
----> is a enlargement
case 2) 1/2
----> is a contraction
case 3) -2
----> is a enlargement
case 4) -1/2
----> is a contraction
Answer:
The length of side BC is 2.8 units
Step-by-step explanation:
* Lets revise how to find the distance between two points
- If there are two points their coordinates are (x1 , y1) and (x2 , y2),
then we can find the distance between them by this rule:
d = √[(x2 - x1)² + (y2 - y1)²]
- Now lets solve the problem
∵ B = (3 , 3)
∵ C = (5 , 1)
- To find the length of BC use the rule of the distance above
- Let point B is (x1 , y1) and point C is (x2 , y2)
∵ x1 = 3 and x2 = 5
∵ y1 = 3 and y2 = 1
∴ BC = √[(5 - 3)² + (1 - 3)²]
∴ BC = √[(2)² + (-2)²]
∴ BC = √[4 + 4] = √8 = 2.8 units
* The length of side BC is 2.8 units
Answer:C(3, –5) and D(6, 0) is;. 5x - 3y = 30.
Step-by-step explanation:
The equation of the line CD expressed in standard form which passes through the points C(3, -5) and D(6,0) is: 5x - 3y=30.
