Find the domain of the rational function below.
f(x)=(x+2)(x-1)/(x-3)(x+2)
Answer:
Domain: { x ∈ R | x ≠ -2, 3 }
Step-by-step explanation:
[tex]f(x)=\dfrac{(x+2)(x-1)}{(x-3)(x+2)}[/tex]
The domain (x-values) of a rational function is all real numbers of x with the exception of those for which the denominator is 0. Therefore, to find the values of x that need to be excluded from the domain, equate the denominator to zero and solve for x.
The denominator for the given function is [tex](x - 3)(x + 2)[/tex]
[tex]\implies (x - 3)(x + 2)=0[/tex]
[tex]\implies (x - 3)=0\implies x=3[/tex]
[tex]\implies (x + 2)=0 \implies x=-2[/tex]
There will be a hole at x = -2 and an asymptote at x = 3.
So the values of x that need to be excluded from the domain are:
x = 3 and x = -2
Therefore, the domain of the given rational function is: { x ∈ R | x ≠ -2, 3 }
Charlie cell phone cost $50 each month plus $0. 05 per text message. His budget is no more than $75 a month. How many text can be send?
Answer:
500
Step-by-step explanation:
let's say charlie sends x messages per month
he spends $50 + 0.05 for each x (message), which comes out to less than or equal to $75.
as an equation, this is
50 + 0.05 x ≤ 75
subtract both sides by 50 to isolate the variable and its coefficient
0.05 x ≤ 25
multiply both sides by 1/0.05 to isolate x
x ≤ 500
the maximum is therefore x = 500 messages
The marked price of a car is $49,500. A person can pay deposit of 30%
and interest at 12% per annum is charged on the outstanding balance.
The total amount payable is to be paid in 2 1/2 years. A) the amount of
each monthly installment b) The hire purchase of the car
The amount of each monthly installment is $1,294 and the hire purchase of the car is: $4,158.
Monthly installementa. Monthly installment
2 1/2 years=30 months
First step
Amount payable=[49,500×(1-.30)] /30 months
Amount payable=(49,500×.70)/30 months
Amount payable=$34,650/30 months
Amount payable=$1,155
Second step
Amount of monthly installment=[$1,155×(1+0.12)
Amount of monthly installment=$1,155×1.12
Amount of monthly installment=$1,293.6
Amount of monthly installment=$1,294 (Approximately)
b. Hire purchase
Hire purchase=$1,155×.12×30 months
Hire purchase=$4,158
Therefore the amount of each monthly installment is $1,294 and the hire purchase of the car is: $4,158.

What is TU???? 24 points
Answer:
4
Step-by-step explanation:
Here we know that T is the midpoint of SU.
Therefore, we know ST and TU are equal.
Setting their values equal, we get:
x+3 = 4x
Then we isolate x by subracting x from both sides:
3=3x
Finally we divide by 3:
1=x
Now we can solve for TU:
4x= 4(1) = 4
Lucas owns a car dealership in Brazil that is having a big sale for the next 3 days. Lucas's car dealership will
lose revenue if it rains because potential customers will stay at home. There is a 50% chance of rain each
of the next 3 days independent of the other days. The table below shows Lucas's potential revenue for his dealership's big sale depending on how many days it rains. What is Lucas's car dealerships' expected revenue over the next 3 days?
Lucas's car dealerships' expected revenue over the next 3 days is $6800
How to determine the expected revenue?The expected revenue is calculated using the following formula of expected value
[tex]E(x) = \sum x * P(x)[/tex]
The data elements on the table are represented as:
Days Revenue
0 3000
1 1800
2 1300
3 800
So, we have:
E(x) = 0 * 3000 + 1 * 1800 + 2 * 1300 + 3 * 800
Evaluate the sum of the products
E(x) = 6800
Hence, Lucas's expected revenue is $6800

5+4+9+2+4=24Cindy puts two different-sized weights on a scale. One size weighs 2 ounces and the other size weighs 5 ounces. All of the weights on the scale
weigh 50 ounces combined.
Create an equation to model a possible number of 2-ounceweights, x, and 5-ounce weights, y, that are on the scale
Answer: 2x+5y=50
Step-by-step explanation:
x=number of 2-ounce weights
y=number of 5-ounce weights
Because of this you will write the total weight (50) is equal to __. On the other end you will multiply the possible number of 2-ounce weights to 2 because this will give you the weight for the 2 ounce. The same is done for the 5-ounce weights. Once you combine both of them you would get the total weight. Which is why 2x+5y=50 is the answer.

lesson 10.2 area of composite figures worksheet assigment
The composite figure includes a rectangle and trapezoid
The area of the composite figure is 810.5cm².
How to determine the area?From the complete question, we have the following parameters:
Shapes: Rectangle and trapezoid
The area of the rectangle is:
Area = Length × Width
So, we have:
Area = 15 × 23
Area = 345cm²
The area of the trapezium
Area = 0.5 × (a + b) ×h
So, we have:
Area = 0.5 × (15 + 34) × 19
Area = 0.5 × 49 × 19
Area = 465.5cm²
Add both areas to calculate the area of the composite figure
Total area = 345cm² + 465.5cm²
Total area = 810.5cm²
Hence, the area of the composite figure is 810.5cm².
