the points (4,0) and (3,9) lie on a particular line. which is its equation in slope intercept form of this line
Answer:
\(y = -9x + 36\)
Step-by-step explanation:
\(\textsf {The slope-intercept form of a line is $y = mx + b$ where m is the slope and b the y-intercept}\\ \\\textsf{Slope is computed using the formula}\)
\(m = \dfrac {(y_{2} - y_{1})} {(x_{2} - x_{1})}\)
\(\sf where \; (x_1,y_1) and (x_2, y_2)\; are\;any\;two\;points\;on\;the\;line\)
\(\textsf{Given that the line passes through (4, 0) and (3, 9) we can compute the slope:}\)
\(m = \dfrac{9 - 0}{3 - 4}\\\\m = \dfrac{9}{-1}\\\\m = -9\)
So the slope of the line is y = -9x + b
We have
y = -9x + b
Add 9x to both sides
y + 9x = -9x + 9x + b
y + 9x = b
switching sides,
b = y + 9x
Plug in the (x, y) values for point (4, 0)
b = 0 + 9(4)
b = 36
So the equation of the line is
\(\boxed{y = -9x + 36}\)

Suppose a department contains 10 men and 15 women. a) How many ways are there to form a committee of 6 people from the department? Explain your answer. b) How many ways are there to form a committee of 6 people from the department, if the number of men in the committee is equal to the number of females in the committee? Explain your answer. c) How many ways are there to form a committee of 6 people from the department, if the number of men in the committee is less than the number of females in the committee? Explain your answer.
a) The number of ways to form a committee of 6 people from the department is 177,100.
b) The number of ways to form a committee of 6 people with an equal number of men and women is 54,600.
c) The number of ways to form a committee of 6 people with more women than men is 91,455.
a) To form a committee of 6 people from the department, we can choose 6 individuals from a total of 25 people (10 men + 15 women). The order in which the committee members are chosen does not matter, and we are not concerned with any specific positions within the committee. Therefore, we can use the concept of combinations.
The number of ways to choose 6 people from a group of 25 is given by the combination formula:
C(25, 6) = 25! / (6! * (25 - 6)!) = 25! / (6! * 19!) = 177,100
Therefore, there are 177,100 ways to form a committee of 6 people from the department.
b) In this case, we need to choose an equal number of men and women for the committee. We can select 3 men from the available 10 men and 3 women from the available 15 women. Again, the order of selection does not matter.
The number of ways to choose 3 men from 10 is given by the combination formula:
C(10, 3) = 10! / (3! * (10 - 3)!) = 10! / (3! * 7!) = 120
Similarly, the number of ways to choose 3 women from 15 is:
C(15, 3) = 15! / (3! * (15 - 3)!) = 15! / (3! * 12!) = 455
To find the total number of ways to form a committee with an equal number of men and women, we multiply these two combinations:
Total = C(10, 3) * C(15, 3) = 120 * 455 = 54,600
Therefore, there are 54,600 ways to form a committee of 6 people with an equal number of men and women.
c) In this case, we need to form a committee with more women than men. We can choose 1 or 2 men from the 10 available men and select the remaining 6 - (1 or 2) = 5 or 4 women from the 15 available women.
For 1 man and 5 women:
Number of ways to choose 1 man from 10: C(10, 1) = 10
Number of ways to choose 5 women from 15: C(15, 5) = 3,003
For 2 men and 4 women:
Number of ways to choose 2 men from 10: C(10, 2) = 45
Number of ways to choose 4 women from 15: C(15, 4) = 1,365
The total number of ways to form a committee with more women than men is the sum of these two cases:
Total = (Number of ways for 1 man and 5 women) + (Number of ways for 2 men and 4 women)
= 10 * 3,003 + 45 * 1,365
= 30,030 + 61,425
= 91,455
Therefore, there are 91,455 ways to form a committee of 6 people with more women than men.

Finding a Function to Match a Current Grade: 0.0/1.0 Remaining Time: Unlimited Shape For this week's discussion, you are asked to generate a continuous and differentiable function f(x) with the following properties: - f(x) is decreasing at x=−6 - f(x) has a local minimum at x=−3 - f(x) has a local maximum at x=3 Your classmates may have different criteria for their functions, so in your initial post in Brightspace be sure to list the criteria for your function. Hints: - Use calculus! - Before specifying a function f(x), first determine requirements for its derivative f ′
(x). For example, one of the requirements is that f ′
(−3)=0. - If you want to find a function g(x) such that g(−9)=0 and g(8)=0, then you could try g(x)=(x+9)(x−8). - If you have a possible function for f ′
(x), then use the techniques in Indefinite Integrals this Module to try a possible f(x). You can generate a plot of your function by clicking the plotting option (the page option with a "P" next to your function input). You may want to do this before clicking "How Did I Do?". Notice that the label " f(x)= " is already provided for you. Once you are ready to check your function, click "How Did I Do?" below (unlimited attempts). Please note that the bounds on the x-axis go from -6 to 6 .
To find a function that satisfies the given criteria, we can start by determining the requirements for its derivative, f'(x).
Let's break down the given properties and find the corresponding requirements for f'(x): f(x) is decreasing at x = -6: This means that the slope of the function should be negative at x = -6. Therefore, f'(-6) < 0. f(x) has a local minimum at x = -3: At a local minimum, the slope changes from negative to positive. Thus, f'(-3) = 0. f(x) has a local maximum at x = 3: At a local maximum, the slope changes from positive to negative. Hence, f'(3) = 0.
Now, let's integrate f'(x) to obtain f(x): Integrating f'(x) = -6 < x < -3 will give us a decreasing function on that interval. Integrating f'(x) = -3 < x < 3 will give us an increasing function on that interval. Integrating f'(x) = 3 < x < 6 will give us a decreasing function on that interval. To simplify the process, let's assume that f'(x) is a quadratic function with roots at -6, -3, and 3. We can represent it as: f'(x) = k(x + 6)(x + 3)(x - 3), where k is a constant that affects the steepness of the curve. By setting f'(-3) = 0, we find that k = -1/18.
Therefore, f'(x) = -1/18(x + 6)(x + 3)(x - 3). Integrating f'(x) will give us f(x): f(x) = ∫[-6,x] -1/18(t + 6)(t + 3)(t - 3) dt. Evaluating this integral is a bit complicated. Let's denote F(x) as the antiderivative of f(x): F(x) = ∫[-6,x] -1/18(t + 6)(t + 3)(t - 3) dt. Now, we can find f(x) by differentiating F(x): f(x) = d/dx[F(x)]. To get an explicit equation for f(x), we need to calculate the integral and differentiate the resulting antiderivative. Once you have the equation for f(x), you can plot it on the provided graphing option to verify that it matches the criteria mentioned in the question.

.Mobile banner ads perform significantly better than desktop banners.
False or true?
It is false that mobile banner ads perform significantly better than desktop banners.
There is no clear consensus on whether mobile banner ads or desktop banner ads perform better. The effectiveness of banner ads depends on various factors such as the placement of the ad, its design, and the target audience.
However, it is true that mobile usage has been increasing rapidly in recent years, and more people are accessing the internet through their mobile devices than through desktop computers. Therefore, it is important for advertisers to optimize their ads for mobile devices and ensure that they are mobile-responsive.
Nevertheless, it cannot be generalized that mobile banner ads are more effective than desktop banner ads. The effectiveness of an ad should be evaluated on a case-by-case basis, taking into account the specific objectives, target audience, and design of the ad.
Therefore, it is important for advertisers to test their banner ads on both desktop and mobile devices to determine which platform works best for their specific campaign. And the given statement is false.

Two angles of a quadrilateral measure 125° and 35°. The other two angles are in a ratio of 3:5. What are the measures of those two angles?
Answer:
120° and 80°
Step-by-step explanation:
quadrilateral = 360°
125° + 35° = 160°
360° - 160° = 200°
3/5 of 200° = 120°
200° - 120° = 80°
Answer:
Step-by-step explanation:
Finding the missing angles of quadrilateral:
Ratio of other two angles = 3 : 5
Other two angles are 3x , 5x
Sum of all angles of quadrilateral = 360
125 + 35 + 3x + 5x = 360
Combine like terms
160 + 8x = 360
Subtract 160 from both sides
8x = 360 - 160
8x = 200
Divide both sides by 8 to isolate x
x = 200/8
x = 25
5x = 5*25 = 125
3x = 3*25 = 75
The other two angles are 125° , 75°

on the trip from detroit to colombus, ohio, mrs smith drove an average speed of 60 mph. returning, her average speed was 55 mph. if it took her 1/3 of an hour longer on the return trip, how far is it from detroit to columbus
Distance from Detroit to columbus is 220 miles
It is given in the question,
The average speed Mrs. smith drove = 60 mph.
Returning, her average speed was 55 mph.
Time taken = 1/3 of an hour longer on the return trip
We have to Find total distance between Detroit and Columbus
So, Let the distance between Detroit and Columbus be "x" miles
Average speed = 60
So, time taken by her to cover distance of x miles with speed of 60 mph
Time = Distance / speed
=> t = x / 60
She Took x/60 hours to reach Columbus
While returning her speed was 55 mph.
So, time taken by her to cover the same distance but at a speed of 55 mph :
=> t = x / 55
Now we are given that she took 1/3 of hour more while returning .
So, \(\frac{x}{55} - \frac{x}{60} = \frac{1}{3}\)
⇒ x/660 = 1/3
=> x = 660/3
=> x = 220 miles
Hence , Detroit is 220 miles far from Columbus

In the diagram below A' B'C'D' is an enlargement of ABCD. AD = 12 cm, |DC| = 8 cm and A'D' = 20 cm Find A' B.
Scale factor = 5/3, AB = 4√5 cm, and perpendicular distance of scale factor is so A'B' = (20/3)√5 cm.
To find A'B, we want to initially decide the scale element of the growth. We know that Promotion = 12 cm and A'D' = 20 cm, so the scale factor is:
scale factor = A'D'/Promotion = 20 cm/12 cm = 5/3
This implies that each side of A'B'C'D' is 5/3 times the length of the relating side of ABCD.
To find A'B, we can zero in on the level side of the square, which relates to Stomach muscle in ABCD. We know that |DC| = 8 cm, so |BC| = |DC| = 8 cm. Since the scale factor is 5/3, we have:
|A'B'| = (5/3) * |AB|
We can utilize the Pythagorean hypothesis to track down |AB|. Let x be the length of |AB|, then, at that point:
\(x^2 + 8^2 = 12^2\)
Working on this situation, we get:
\(x^2 = 144 - 64 = 80\)
Taking the square base of the two sides, we get:
x = √80 = 4√5
Hence:
|A'B'| = (5/3) * |AB| = (5/3) * 4√5 = (20/3)√5
So the length of A'B' is (20/3)√5 cm.
