Which of the equations below could be the equation of this parabola?
Answers
Answer:
The correct answer is C
Your welcome:)
The equation below could be the equation of this parabola is y = -5x².
Option A is the correct answer.
What is a parabola?A parabola is an equation of a curve, such that any point on the curve is equidistant from a fixed point called the focus and a fixed line called the directrix of the parabola.
The equation of a parabola:
y = a(x - h)² + k
We have,
Since the parabola vertex is at (0,0) and is open to the left, the equation of the parabola must be of the form:
y = a x², where a is a positive constant.
Now,
The only equation that fits this form is y = -5x².
Thus,
The equation below could be the equation of this parabola is y = -5x².

4x+4 -2x =5-x
combind 4x and -2x
2x+4=5-x
combind 2x and x
3x+4=5
subtract 4 from 5
3x=1
3÷3 and 1÷3
x=3
Answer:
x = 0.33
Step-by-step explanation:
4(x + 1) - 2x = 5 - x
4x + 4 - 2x = 5 - x
4x - 2x + 4 = 5 - x
2x + 4 = 5 - x
2x + x + 4 = 5 - x + x
3x + 4 = 5
3x = 5 - 4
3x = 1
3x ÷ 3 = 1 ÷ 3
x = 0.33
For each of the following studies, say whether you would use a t test for dependent means or a t test for independent means.
a. A researcher randomly assigns a group of 25 unemployed workers to receive a new job skills program and 24 other workers to receive the stan- dard job skills program, and then measures how well they all do on a job skills test.
b. A researcher measures self-esteem in 21 students before and after taking a difficult exam.
c. A researcher tests reaction time of each member of a group of 14 individuals twice, once while in a very hot room and once while in a normal- temperature room.
Answers
Answer:
1. T test for independent means
2. T test for dependent means
3. T test for dependent means
Step-by-step explanation:
In number 1, the two groups are unrelated. The first group has 25 subjects and they're all unemployed. The second group has 24 subjects and their employment status is not stated and might not be the same all through. Also, the first group is receiving a new type of job skills program while the second group is taking the standard job skills program.
- The groups in the experiment are unrelated
- The tests in the research are unrelated
- The purpose of the research is unreasonable - the researcher seeks to measure how well all 49 subjects perform on 'a' job skills test! No comparison between the scores or mean scores of the two groups.
In number 2, the researcher uses the same subjects and also measures the same variable but twice. This is a good example of a study where the t test for dependent means can be taken. Same applies in case 3.

Answers
Answer:
14
Step-by-step explanation:
Because right angles are 90 degrees, we need to subtract 34 from 90 which gets us 56. That means 56 = 4x, so 56/4 = 14, therefore X = 14.
Hope this helps!
Both angles form a right angle which is 90 degrees.
Angle 2 would equal 90 degrees - angle 1
Angle 2 = 90 -34 = 56
So now we know 4x = 56
To find x divide both sides by 4
X = 14

How does the stimulus check impact society please help me please i really need help please
Answers
Answer:
The stimulus check impacts society because it helps people or rather encourages people to invest. Not only individuals but also businesses. It also shows how the stimulus check gives more than peoples incomes. Not everyone can get the stimulus check, only tax payers who pay taxes every year and have a public job. This impacts society because not everyone can get the stimulus check, and some people receive lots of money and other people might get just a little. At the end of the day, it all depends on how much taxes you are paying each year and which job you have.
