Which expression is equal to (f - g)(x)?
ANSWER
[tex](f-g)(x) = 11 |x| - 32[/tex]
EXPLANATION
The functions are:
[tex]f(x) = 10 |x| + 26[/tex]
[tex]g(x) = 58 - |x| [/tex]
[tex](f-g)(x) = f(x) - g(x)[/tex]
Plug in the functions:
[tex](f-g)(x) = 10 |x| + 26 - (58 - |x| )[/tex]
[tex](f-g)(x) = 10 |x| + 26 - 58 + |x| [/tex]
[tex](f-g)(x) = 10 |x| + |x| + 26 - 58[/tex]
[tex](f-g)(x) = 11 |x| - 32[/tex]
The correct choice is A
Answer:
11|x|-32 hope this helps :D
Step-by-step explanation:
10|x|+26-(58-|x|)
10|x|+26-58+|x|
10|x|+|x|+26-58

For the z-score for the 11.6 data point
Answer:
z = 1.3345
Step-by-step explanation:
The z-score for a given data point, say x, from a normal distribution with a given mean and population standard deviation is usually calculated using the formula;
[tex]z=\frac{x-mean}{standard deviation}[/tex]
The following information is available;
mean = 7
population standard deviation = 3.522
x = 11.7
We simply employ the above formula to determine the z-score associated with the 11.7 data point;
[tex]z=\frac{11.7-7}{3.522}=1.3345[/tex]
Find the missing side length. When the area is 12ft.
Answer: Since you are finding the missing side of a rectangle, it is 3.
Step-by-step explanation:
Area of rectangle= (l)(w)
The length of the missing side is 3ft.
What is Area ?Area is defined as the space occupied by a flat surface .
It is measured in square units.
It is given in the question
A rectangle with one side as 4ft.
Area of the rectangle = 12 sq.ft
Other side = ?
Area of a rectangle is given by Length * Breadth
Area = one side * other side
Substituting the values
12 = 4 * other side
other side = 3 ft.

To the nearest hundred what is the value of X
Answer:
41.51
Step-by-step explanation:
We can find the value of x using the trigonometry identify.
Cos (41) = x/55
x = 55cos (41)
x = 41.51
ANSWER
[tex]x = 41.51[/tex]
EXPLANATION
The given triangle has a right angle.
We were given an acute angle that measures 41°
The hypotenuse of the given right triangle is 55.
Since x is adjacent to the given angle and we also know the hypotenuse, we use the cosine ratio to find x.
[tex] \cos(41 \degree) = \frac{x}{55} [/tex]
Therefore
[tex]x = 55 \cos(41 \degree) [/tex]
[tex]x = 41.509[/tex]
We round to the nearest hundredth to obtain,
[tex]x = 41.51[/tex]
A fast food restaurant sells burgers, chicken sandwiches, and entree salads. If a customer buys a burger, the probability they buy french fries is 0.80. Fifty percent of customers who purchase a chicken sandwich also buy fries, but only 10% of those buying an entree salad buy fries. Of all customers, 65% buy a burger, 20% a chicken sandwich, the rest buy an entree salad.
What proportion of customers get a burger and fries?
Answer:
52%
Step-by-step explanation:
We are told that, of all customers 65% buy a burger. This would imply that the proportion of customers who buy a burger is 0.65.
Moreover, if a customer buys a burger, the probability they buy french fries is 0.80. This implies that the proportion of customers who buy fries given that they bought a burger is 0.8.
Therefore, the proportion of customers who get a burger and fries is simply the product of the two probabilities;
= 0.65*0.8
= 0.52
Therefore, 52% of all customers get a burger and fries
which is a prime number 7 63 33 27

F(x) or G(x)

Answer:
A. f(x)
B. g(x)
Step-by-step explanation:
The initial amount if the value of the function at x = 0.
Here that value is 2000 for the f(x) and 1000 for the g(x), so the f(x) has the higher initial value.
For the second part, by looking at the graph, you can determine that the function for the g(x) is 1000(3)^x (because the g(1) is 3000). Plugging in two for both the function, you get the f(x) = 8,000 and the g(x) = 9,000, so the g(x) has the greater amount of bacteria after two days.

write the equation for an exponential function, in the form axb^x, whose graph passes through the coordinates points (1, 7.5) ( 3, 16.875)
Answer:
see explanation
Step-by-step explanation:
The equation of the exponential function in the form
y = a[tex]b^{x}[/tex]
Substitute the given points into the equation and solve for a and b
Using (1, 7.5), then
7.5 = ab → (1)
Using (3, 16.875), then
16.875 = ab³ → (2)
Divide (2) by (1)
[tex]\frac{ab^3}{ab}[/tex] = [tex]\frac{16.875}{7.5}[/tex], hence
b² = 2.25 ( take the square root of both sides )
b = 1.5
Substitute b = 1.5 into (1)
1.5a = 7.5 ⇒ a = 5
The exponential function is y = 5[tex](1.5)^{x}[/tex]

We collect the least common multiple of the denominators to get:
[tex]\frac{(r+2)(r+1)-3(r+4)}{(r+4)(r+1)}[/tex]
Expand the numerator:

[tex]\frac{ r^2-10}{(r+4)(r+1)}[/tex]
Step-by-step explanation:
[tex]\frac{r+2}{r+4} - \frac{3}{r+1}[/tex]
To simplify the fractions we take common denominator
LCD is (r+4)(r+1)
we try to get same denominator on both fraction
multiply the first fraction by r+1 and second fraction by r+4
[tex]\frac{(r+2)(r+1)}{(r+4)(r+1)} - \frac{3(r+4)}{(r+1)(r+4)}[/tex]
(r+2)(r+1) becomes r^2 +3r+2
3(r+4) becomes 3r+12
[tex]\frac{ r^2 +3r+2}{(r+4)(r+1)} - \frac{3r+12)}{(r+1)(r+4)}[/tex]

a penny is dropped from the top of the statue of liberty which is 305 feet tall . the height of the penny, (h,) at time (t) seconds can be repesented by the equation h(t) = -16t^2 + 305. After 4 seconds how much further does the penny need to travel before it hits the ground.
Answer: Penny need to travel 49 feet before it hits the ground.
Step-by-step explanation:
Since we have given that
[tex]h(t)=-16t^2+305[/tex]
Here, h denotes the height of the penny
t denotes the time in seconds.
Now, t = 4 seconds
So, the penny needs to travel before it hits the ground is given by
[tex]h(4)=-16(4)^2+305\\\\h(4)=-16\times 16+305\\\\h(4)=256-+305\\\\h(4)=49\ feet[/tex]
Hence, Penny need to travel 49 feet before it hits the ground.
After 4 seconds, the penny needs to travel an additional 49 feet before it hits the ground.
Explanation:The equation h(t) = -16t^2 + 305 represents the height of the penny at time t seconds. To find out how much further the penny needs to travel before it hits the ground after 4 seconds, we need to substitute t = 4 into the equation and solve for h.
h(4) = -16(4)^2 + 305
h(4) = -256 + 305
h(4) = 49 feet.
Therefore, the penny needs to travel an additional 49 feet before it hits the ground.

Step-by-step explanation:
Whats 3320/.80?
The total cost of clicks $2656.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Per click charges= 80 cents
Total clicks= 3320
So, charges for 3320 clicks
= 3320 x 80

In a lottery game, a player picks six numbers from 1 to 20. If the player matches all six numbers, they win 30,000 dollars. Otherwise, they lose $1.
What is the expected value of this game?
The expected value of the lottery game is -$0.62, suggesting a long-term average loss of 62 cents per game played. This value is calculated by considering the probability of each outcome and the associated gain or loss.
Explanation:In order to calculate the expected value of the lottery game, we must first understand what expected value truly represents. The expected value is essentially a description of the average outcome of a series of events if these events are repeated many times. It's a statistical concept used to predict the long-range behavior of random events, such as lottery games.
The expected value is calculated as the sum of all possible values each multiplied by the probability of its occurrence. For the lottery game described, there are two possible outcomes: a win of $30,000 or a loss of $1.
The probability of winning is extremely low. In this game, the player is attempting to choose the correct 6 numbers out of 20, which is a 1 in 38,760 chance. Whereas, the probability of losing is extremely high, practically 38,759 out of 38,760.
Thus, the Expected Value (E) can be calculated as follows: (probability of winning x winnings) + (probability of losing x loss). Plugging in our values gives us an expected value of -$0.62, rounded to the nearest cent. This figure indicates that if one were to play this game repeatedly, their average loss per game would be about 62 cents.
