what is an oxidation reaction?
Fe + O2 —(H2O)—> Fe2O3
given: f(x) 3x-1. g(x) 2x^2-3
=(3x-1) + (2x^2-3)
= 3x-1 + 2x^2-3
=5x^2-4
can someone tell me if its correct, im not sure if i am ;-;
f(x) = 3x - 1 = 0
f(x) = x = 1/3
By putting the value of x in g(x), we get
g(x) = 2(1/3)^2 - 3
g(x) = 2(1/9) - 3
g(x) = 2/9 - 3
g(x) = -25/9
Answer:g(x) = -25/9
Answer:
[tex]2x^{2} + 3x - 4[/tex]
Explanation:
(f + g)(x)=(3x-1)+(2x^2-3)
Simplify:

What do you think happens to the matter in a food sample as it is burned?
Burning and other changes in matter do not destroy matter. The mass of matter is always the same before and after the changes occur. The law of conservation of mass states that matter cannot be created or destroyed
The thing that is happen in a food sample as it is burned is the chemical and physical change.
What is combustion reaction?Comubustion reactions are those reactions in which organic compound get burnt in the presence of oxygen for the formation of carbon dioxide gas and water molecule.
If the food sample contains the organic compound then it will convert into water and carbon dioxide gas and if it contains the matter in the form of inorganic compounds then it will convert into another product but having the same mass.
Hence if matter of food sample is burned then it will convert into small products as a result of physical or chemical change.

How do I convert 3.221×10^−3 mm to standard notation
Answer:
0.003221
Explanation:
When we multiply anything by 10 times a power, we follow the base 10 decimal system.
To convert 3.221 × 10⁻³ from scientific notation to standard notation, simply move the decimal place 3 places to the left:
3.221 × 10⁻³ = 0.003221

A loaf of bread has a mass of 0.5kg and a volume of 2500cm³. what is the density of the bread
Density is mass divided by volume.
Since mas is 0.5kg we need to convert it to grams. Using conversion factors we get the mass of the bread to be 500g.
So densty=500/2500
density =1/5 grams per cubic centimeter

A researcher is measuring changes in the density of the upper atmosphere over time. Which units should be used for the density measurements?
Answer:
lbm/ft³ or psi/ft
Explanation:
The description in the question shows the density to measured is that of gases (upper atmosphere). The density of a gas can be described as the mass of the gas divided by the volume of the gas at a certain temperature and pressure. It's unit can be represented as lbm/ft³ or psi/ft.
NOTE:
"lbm" means "lean body mass" which is a unit for mass or weight and can be described as the pound mass
"psi" means "pound per square inch"; is also a unit for mass or weight
Scientist at the CDC (Center for Disease Control) in Atlanta, GA are currently developing and testing new treatments and vaccines for the coronavirus. What kind of research are they conducting?
Answer:
Applied research
Explanation:
The process of developing a new vaccine involves the use of known scientific theories to address specific problems. Here, the outcome of several basic research are put into use to arrive at a targeted outcome. This outcome/product can be continuously modified (if it shows early promise) until the desired effect is achieved and if no "promise" is discovered at critical points of this research, work on this theory (for this research) is suspended another theory is pursued.
This process (described above) in which scientists continuously develop new treatments and/or vaccines and continuously subject it to testing until the desired effect is achieved can be referred to as Applied research.

Explanation:
A scientist grew bacteria on gel in her lab.
She wanted to find out if bacteria would grow faster on gel A or gel B.
she placed a few bacteria on gel A and a few on gel B.
After 24 hours, she observed how many bacteria were present.
Identify the independent and dependent variables.
Answer:
The independent variable is type of gel and the dependent variable is the number of bacteria.
Explanation:
An experiment generally tests how one variable is affected by another. The affected variable is called the dependent variable. In the plant experiment shown above, the dependent variable is plant growth. The variable that affects the dependent variable is called the independent variable. In the plant experiment, the independent variable could be fertilizer—some plants will get fertilizer, others will not. The scientists change the amount of the independent variable (the fertilizer) to observe the effects on the dependent variable (plant growth). An experiment needs to be run simultaneously in which no fertilizer is given to the plant. This would be known as a control experiment. In any experiment, other factors that might affect the dependent variable must be controlled. In the plant experiment, what factors do you think should be controlled? (Hint: What other factors might affect plant growth?)
tony ate 3/4 of the pizza. mike ate 7/16 of the pizza. how much more did tony eat than mike
Answer:
5/16
Explanation:
make them have a common denominator
3/4 needs to be times by 4
so it's
12/16 then you minus 7/16
the answer is
5/16
Answer: 5/16
Explanation:
Multiply tonys 3/4 by 4 in order to get the same denominator as mike's 7/16. You should get 12/16 since 4x3=12, and now you can subtract the smaller fraction 7/16 from the bigger one 12/16, you should get a difference of 5/16.

What most likely occurred during this demonstration?
In a science demonstration, a teacher mixed zinc (Zn)
with hydrogen chloride (HCI) in a flask and quickly
attached a balloon over the mouth of the flask Bubbles
formed in the solution and the balloon inflated,
O The Zn and HCl both retained their identity
Either Zn or HCI, but not both, retained its identity
O Evaporation of one of the substances occurred
One or more new substances formed
Answer:
Hydrogen gas and a salt formed at the end of the reaction.
Explanation:
Hydrogen Gas has formed which inflated the balloon
Usually, metals and acids react to form a salt and Hydrogen Gas.
Here's what happened:
Zn (s) + 2HCl (aq) → [tex]ZnCl_2[/tex](aq) +[tex]H_2[/tex](g)
Cheers :)
Answer:
One or more new substances formed.
Explanation:
This is an example of a chemical property because bubbles formed, and the mixture produced a gas which allowed the balloon to inflate. The production of bubbles is an indicator of a chemical change. When a chemical change occurs, one or more new substances form as a result.

As the frequency of electromagnetic waves increases, what happens to the wavelength?
O It increases.
O It decreases
It fluctuates.
O It remains constant.
Answer:
It decreases.
Explanation:
As the frequency of electromagnetic waves increases, the wavelength decreases.
What is frequency?Frequency defines the number of waves passing through a fixed area over a period of time. So if the time we take for the wave to pass is 1/2 second, it is usually 2 per second. If it takes 1/100 of an hour, it is usually 100 per hour.
What is an example of frequency?The definition of frequency is how often something happens. An example of blinking an eye blink 47 times in one minute. (physics) The degree to which a recurring event occurs, such as a full-wave cycle.
