Below are two different functions, f(x) and g(x). What can be determined about their y-intercepts? graph going through negative 1, negative 1 and negative 4, negative 1 x g(x) 4 9 6 13 8 17 (1 point) The function g(x) has a higher y-intercept. The function f(x) has a higher y-intercept. They both have the same y-intercept. The relationship between y-intercepts cannot be determined.
Answers
Answer:
The function g(x) has a higher y-intercept.
Step-by-step explanation:
First function f(x):
Slope = (-1, - (-1) / -4 - -1) = 0
So its equation is y = -1.
The y-intercept is (0, -1).
Second function g(x):
Slope = (13-9)/ (6-4) = 2.
y - y1 = m(x - x1) where m = slope and (x1, y1) is a point on the line, so we have:
y - 9 = 2(x - 4)
y = 2x - 8 + 9
y = 2x + 1.
So the y-intercept is (0, 1).
How much commission will George receive for the sale of a $250,000 home if he receives 2 1/2% of the selling price?
Answers
Answer:
625,000
Step-by-step explanation:
250,000 * 5/2 = 625,000
The commission that George will receive for the sale of a [tex]\$[/tex]250,000, if he receives 2 1/2% of the selling price is $6,250.
What is commission?"A commission is a piece of work that someone is asked to do and is paid for."
Sale is [tex]\$[/tex]250,000
Converting 2 1/2% in improper fraction is 5/2 %
So, commission will be [tex]\(2.5*250,000 /100[/tex] = 625,000/100 = 6250
Hence, the commission that George will receive is $6,250.

Best of Luck!
Answer:
1/6
Step-by-step explanation:
He ate 1/2 of 1/3 of the cake, so the fraction of the whole cake he ate is 1/2 x 1/3. Multiplying fractions is easy, simply multiply the numerator of each fraction (the numbers at the top of each fraction) and the denominator of each fraction (the numbers at the. bottom of each fraction). Therefore, 1/2 x 1/3 = 1/6.

An airplane is flying in a direction of 165° with an airspeed of 650 mph. The wind is blowing at 50 mph in a direction of N 30°E What is the ground speed and direction of the plane?
A) ground speed: 658 mph; direction 108°
B) ground speed: 639 mph; direction 161°
C) ground speed: 686 mph; direction 108°
D) ground speed: 698 mph; direction 161°
Answers
Direction is usually specified as bearing, however, with regards to vectors direction is specified relative to the positive, x-axis
The correct option for the ground speed and direction of the plane is option B
B) Ground speed: 639 mph; direction 161°
The given parameters are;
Direction of airplane = 165° (vector, measured from the horizontal x-axis)
Airspeed of airplane = 650 mph
The speed of the wind blowing = 50 mph
The direction of the wind = N30°E
Required:
The ground speed of the airplane
Solution:
The velocity of the airplane in vector form is found as follows;
[tex]\overset \longrightarrow P[/tex] = 650 × cos(165)·i + 650 × sin(165)·j ≈ -628·i + 168·j
The velocity of the wind in vector form is found as follows;
[tex]\overset \longrightarrow W[/tex] = 50 × cos(60)·i + 50 × sin(60)·j ≈ 25·i + 43·j
The sum of the vectors, [tex]\overset \longrightarrow R[/tex] = The ground speed, therefore;
[tex]\overset \longrightarrow R[/tex] = [tex]\overset \longrightarrow P[/tex] + [tex]\overset \longrightarrow W[/tex]
[tex]\overset \longrightarrow R[/tex] = (25 - 628)·i + (43 + 168)·j = -603·i + 211·j
The magnitude of the ground speed = √((-603)² + 211²) ≈ 639
The magnitude of the ground speed ≈ 639 mph
The direction, Φ ≈ arctan(211/(-603)) ≈ -19°
Φ is measured from the negative x-axis in the clockwise direction, therefore;
The direction of the airplane from the positive x-axis, in the anticlockwise direction, θ = 180° + Φ
θ = 180° + (-19) = 161°
The direction of the airplane measured from the positive x-axis, θ ≈ 161°
Therefore, the correct option is ground speed; 639 mph; direction 161°

Part B: Is the vertex of the graph of f(x) going to be a maximum or minimum? What are the coordinates of the vertex? Justify your answers and show your work. (3 points)
Part C: What are the steps you would use to graph f(x)? Justify that you can use the answers obtained in Part A and Part B to draw the graph. (5 points)
(10 points)
Answers
Part A
[tex]2x^2 -x-10=0\\\\(x+2)(2x-5)=0\\\\x=-2, \frac{5}{2}[/tex]
So, the x-intercepts are (-2,0) and (5/2, 0).
Part B
The vertex will be a minimum because the leading coefficient of the quadratic is positive, meaning the graph will open up.
The vertex has an x-coordinate that is the average of the roots, which in this case is 1/4.
[tex]f(1/4)=-81/8[/tex]
So, the coordinates of the vertex are [tex]\left(\frac{1}{4}, -\frac{81}{8} \right)[/tex]
Part C
Plot the two x-intercepts and the vertex. Then, draw a parabola through these points that opens up.

A study took a group of adults and randomly divided them into two groups. One group was told to drink tea every night for a week, while the other group was told not to drink tea that week. Researchers then compared when each group fell asleep. Does this describe an observational research study or an experimental research study?
Answers
Answer:
2nd one
Step-by-step explanation:
experimental research
The case described here is an experimental research study.
In an experimental research study, the researcher deliberately manipulates one or more variables (in this case, whether or not the participants drink tea) and observes the effects on other variables (in this case, the time each group falls asleep). The researcher randomly assigns participants to different groups, ensuring that any differences observed between the groups can be attributed to the manipulation of the variable of interest.
In this scenario, the researcher randomly divided the adults into two groups and instructed one group to drink tea every night while the other group was told not to drink tea. By manipulating the variable (tea consumption) and comparing the outcomes (time of falling asleep) between the two groups, the study follows the experimental research design.
