1. We need to plug in values of x into the functions f(x) and g(x):
f(2) = 2.5 * 2 - 10.5 = -5.5 g(2) = [tex]64 * (0.5^2)[/tex] = 16
f(3) = 2.5 * 3 - 10.5 = -3 g(3) = [tex]64 * (0.5^3)[/tex] = 8
f(4) = 2.5 * 4 - 10.5 = -0.5 g(4) = [tex]64 * (0.5^4)[/tex] = 4
f(5) = 2.5 * 5 - 10.5 = 2 g(5) = [tex]64 * (0.5^5)[/tex] = 2
f(6) = 2.5 * 6 - 10.5 = 4.5 g(6) = [tex]64 * (0.5^6)[/tex] = 1
2.
(a) Notice that at 14 on the x-axis, the blue line is above 4. Meanwhile, at 14, the red line is less than 2. Obviously, we can see that if the printed ad revenue was less than 2 and the online ad revenue was greater than 4, that's more than a double, so the lead marketing executive is correct.
(b) The approximate year that the revenues were equal is the place where the lines intersect. It's approximately at Year 7.5.
3.
(a) The Western Beach is clearly decreasing; it is decreasing by 2 ft per year. Meanwhile, the Dunes Beach is clearly increasing; it's increasing by 5 ft per year. (I'm not sure what kinds of "patterns" you're looking for).
(b) Year 11 and 12; this is because here, Western is going from 78 to 76 ft and Dunes is going from 75 to 80, so they'll likely coincide sometime in that time interval.
(c) One thing you can do is to create equations (of the form y = mx + b) for each of the beaches and then set those linear equations equal to each other.
Answer:
Page 1:
f(2) = -5.5
f(3) = -3
f(4) = -0.5
f(5) = 2
f(6) = 4.5
Notice the values are increasing by 2.5
g(2) = 16
g(3) = 8
g(4) = 4
g(5) = 2
g(6) = 1
Notice the values are getting divide by half
Page 2:
A:
At 14 years, the revenue for online ads are a little over 4 million dollars. However, for printed ads, the revenue is only about 1.5 million dollars. If you double 1.5 million, you will only get 3 million. That is less than 4 million. So, the lead marketing executive was correct.
B:
The approximate year that the two revenues were equal was approximately 7 and a half (or 7.5).
Page 3:
A:
For the Western Beach, the width is decreasing by exactly 2 feet per year. For the Dunes Beach, the width is increasing by exactly 5 feet per year.
B:
The beaches will have the same width somewhere between years 11 and 12.
C:
A good way to get an even better approximation on when these beaches will have the same width, is to write them in slope-intercept form. The Western Beach equation will look like f(x) = -2x + 100 and the Dunes Beach equation will look like g(x) = 5x + 20.

Two hoses of different sizes are used to fill a pool. The smaller hose can fill the pool in 1.5 times as long as the larger hose. If both hoses
are used it takes 9 hours to fill the pool. If only the larger hose is used, how many hours will it take to fill the pool?
Answer:
15
Step-by-step explanation:
Let x represent the number of hours it takes the larger hose to fill the pool. Then each hour, it contributes 1/x of the pool volume. Similarly, the other hose contributes a volume of 1/(1.5x) each hour.
The two hoses together contribute a volume of 1/9 of the pool volume each hour:
1/x +1/(1.5x) = 1/9
2.5/(1.5x) = 1/9 . . . . combine the fractions
22.5/1.5 = x . . . . . . multiply by 9x
15 = x
It takes the larger hose 15 hours to fill the pool alone.

Answer:
What is your exact question?
Step-by-step explanation:
Explanation:
The notation [tex]A \cap B[/tex] means "the overlapped region between circles A and B". There is only one value in this region, and it is the "8". This is in the lower half of this region as the upper half is empty.
There are 12 values in the set {2,4,6,8,10,12,14,16,18,20,24} which we can see by counting them out, or we can note how 24 = 2*12 and how we started with 2 = 2*1. So basically we have...
2 = 2*14 = 2*26 = 2*38 = 2*410 = 2*512 = 2*614 = 2*716 = 2*818 = 2*920 = 2*1022 = 2*1124 = 2*12So again we have 1 value in the overlapped region between A and B, out of 12 values total. So that's why the answer is 1/12.

Answer:
(0, 9)
Step-by-step explanation:
The circle defined by the equation ...
(x -h)^2 +(y -k)^2 = r^2
has its center at (h, k).
We think your circle's equation is ...
x^2 + ( y − 9 )^2 = 81
so it would have its center where h = 0 and k = 9.
The center is (0, 9).

The rectangle below has an area of 81-x^2 square meters and a width of 9-x meters. What expression represents the length of the rectangle?
For this case we have that by definition, the area of a rectangle is given by:
[tex]A = w * l[/tex]
Where:
w: Is the width of the rectangle
l: is the length of the rectangle
According to the data of the statement we have:
[tex]A = 81-x ^ 2\\w = 9-x[/tex]
So, the length is given by:
[tex]l = \frac {A} {w}\\l = \frac {81-x ^ 2} {9-x}[/tex]
We factor the numerator:
[tex]l = \frac {(9 + x) (9-x)} {9-x}[/tex]
We simplify:
[tex]l = 9 + x[/tex]
So, the length is [tex]9 + x[/tex]
Answer:
[tex]9 + x[/tex]

A car travels at a steady speed of 10 m/s what distance is covered in one minute
Answer:600
Step-by-step explanation:
There are 60 seconds in one minute so you would need to multiply 60 by 10
A car traveling at a steady speed of 10 m/s will cover a distance of 600 meters in one minute.
Explanation:The distance covered by a car moving at a steady speed can be calculated from the simple physics formula for speed: speed = distance/time. In this case, the speed of the car is given as 10 m/s, and the time is given as 1 minute. However, time needs to be in the same units as the speed, so we need to convert minutes to seconds. As one minute is equal to 60 seconds, we can use this conversion. Now, to solve for distance, we rearrange the equation to look like: distance = speed * time. Substituting the given speed and time, we get: distance = 10 m/s * 60 s = 600 m. Therefore, a car traveling at a steady speed of 10 m/s will cover a distance of 600 meters in one minute.

Later x day, She use 540 minutes.
be 45x=540
x,
540/45 = 12
We see in the link:
https://brainly.com/question/16038184?answeringSource=feedPersonal%2FhomePage%2F7
Good lessons!
Final answer:
The correct equation that expresses how many days Meghan used her cell phone is 45n = 540. By dividing both sides by 45, we find that n = 12, indicating she used her cell phone for 12 days.
Explanation:
The question is asking to find the equation that represents the number of days Meghan used her cell phone, given that she used it for 45 minutes each day and the total usage was 540 minutes. To solve this, you would set up an equation where the number of days (n) times the daily usage (45 minutes) equals the total usage (540 minutes).
Therefore, the correct equation would be 45n = 540.
To find out how many days she used her cell phone, you would divide both sides of the equation by 45:
45n / 45 = 540 / 45
n = 12
This means Meghan used her cell phone for 12 days.

Answer:A and CStep-by-step explanation:
If f(x) = -x^2 – 1, and
g(x) = x + 5, then
g(f (x)) = -x^2+[ ?]x + [ ?]
By substituting the expression for f(x) into g(x), g(f(x)) simplifies to -x^2 + 4. The coefficient of x^2 is inherited from f(x), and the constant term changes due to the addition in g(x).
To find g(f(x)), substitute the expression for f(x) into g(x):
g(f(x)) = g(-x^2 - 1)
Now, replace x in g(x) with -x^2 - 1:
g(f(x)) = (-x^2 - 1) + 5
Combine like terms:
g(f(x)) = -x^2 + 4
So, the given expression g(f(x)) = -x^2 + 4. The coefficient of x^2 remains -1 from f(x), and the constant term changes from -1 to +4 after adding 5 in the expression g(x).
Here g(f(x)) simplifies to -x^2 + 4, where the coefficient of x^2 is inherited from f(x), and the constant term changes due to the addition in g(x).
Ann increased the quantities of all the ingredients in a recipe by 60%, percent. She used 80 grams (\text{g})(g)left parenthesis, start text, g, end text, right parenthesis of cheese. How much cheese did the recipe require?
Answer:
The recipe required 50 grams of cheese
Step-by-step explanation:
Here in the question, we are made to know that she increased all ingredients by 60%.
Now we want to know the original mass of the cheese if she used 80grams after the 60% increment.
Mathematically, the formula for percentage increase is;
% increase = increment/old value * 100%
Where increment is new value - old value
since we do not know the old value, we can say that it is x. This means that the increment is 80-x
Hence;
60= (80-x)/x * 100
60x = 100(80-x)
60x = 8000-100x
100x + 60x = 8000
160x = 8000
x = 8000/160
x = 50g

A sphere has a diameter of 10 ft. What is the surface area
Answer:
314.15926 square feet
Step-by-step explanation:
Formula for sphere surface area = 4*π r^2
radius = (1/2)*diameter = (1/2)* 10 feet = 5 feet
Area = 4* π*(5)^2 = 100π = 314.15926 square feet
Final answer:
The surface area of a sphere with a diameter of 10 ft is 100π square feet, or approximately 314.16 square feet.
Explanation:
The surface area of a sphere can be calculated using the formula 4πr², where r is the radius of the sphere. Given that the diameter of the sphere is 10 ft, the radius is half of that, which is 5 ft. Plugging the radius into the formula, we get the surface area as 4π(5 ft)² = 4π x 25 ft² = 100π ft². Therefore, the surface area of the sphere with a diameter of 10 ft is 100π square feet, which is approximately 314.16 square feet when π is approximated to 3.1416.

Which do the following most specifically describes a rhombus?? A.a plane figure that is a polygon. B.a quadrilateral with 2 pairs of equal length. D. A polygon with four sides
Answer:
B. A quadrilateral with 2 pairs of equal length
Step-by-step explanation:
analyzing the options:
A. A polygon is a very general definition (polygon is a figure with 3 or more sides) so it does not specifically describe a rhombus.B. This option is much more specific to a rhombus than the other two options because it mentions that it is a quadrilateral so it reduces the generality of calling it a polygon, and it also mentions that there are 2 pairs of equal sides which is true for the rhombus (the top and bottom sides are equal, and the sides are also equal). So this option is correct.C. It is a little more specific than option A because it mentions that you must have 4 sides, but it is not as specific for the rhombus as option BAnswer:
B.a quadrilateral with 2 pairs of equal length
Step-by-step explanation:
A rhombus is a quadrilateral with 4 equal sides in length. A quadrilateral is a closed figure or shape with 4 sides . Other quadrilaterals are parallelograms, square and rectangle .
Opposite sides of a rhombus are parallel and opposite angles are equal. The diagonals meet at the center to form a right angle. The best description of a rhombus among the option is that it is a quadrilateral with 2 pairs of equal length.
Note polygon is too broad to be used to describe a rhombus .Moreover rhombus is not a regular polygon since all the angles are not equal.
