Find the slope of the line passes through the points (2, 5) and (9, 8).
A. 1/7
B.2/7
C. 3/7
D.8/7
Step by Step Explanation:
Given:line passing through points (2,5) and (9,8)To find: Slope of the lineSolution:-
Here, to find the slope of line passing through two points x₁,x₁ and y₁,y₂ is given by:-
[tex]\sf m=\frac{y_2 - y_1}{x_2 - x_1} [/tex]
where,
x₁ = 2
x₂ = 9
y₁ = 5
y₂ = 8
Therefore putting the values , we get
[tex] \sf \: m=\frac{y_2 - y_1}{x_2 - x_1} \\ \\ : \longrightarrow \: \frac{8 - 5}{9 - 2} \\ \\ : \longrightarrow \: \frac{3}{7} [/tex]
Hence, the slope of line passes through the points (2, 5) and (9, 8) is 3/7.
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 }
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.

The volume of any shape is the amount of space in it.
The volume of the cylinder is 1570 square units
How to determine the volume?The question is incomplete. Assume the following parameters
Shape = Cylinder
Radius, r = 10
Height, h = 5.
The volume of a cylinder is:
V = πr^2h
So, we have:
V = 3.14 * 10^2 * 5
Evaluate the product
V = 1570
Using the assumed values, the volume of the cylinder is 1570 square units

Cindy 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.

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

A college professor wants to survey a sample of students taking his course. Here are some details about his course:
He teaches 5 sections of the course.
There are 250 total students across those sections.
There are 50 graduate students and 200 undergraduate students taking the course.
Each section has about 50 students (some graduate and some undergraduate).
The professor wants to take a sample of 30 students for a survey. He suspects that opinions on the survey may differ the most based on student type (graduate or undergraduate), so he wants to design his sample to take that into account. Which of these strategies will accomplish his intended design?
a. Randomly select 6 students from each section for the survey.
b. Randomly select 6 graduate students and 24 undergraduate students for the survey
c. For each section, randomly select one of the first 8 students to arrive to class, and every 8th student thereafter to take the survey.
d. Randomly select one of the sections and give the survey to every student in that section
Answer: B, Randomly select 6 graduate students and 24 undergrad students for the survey.
Step-by-step explanation: This guarantees that each type is proportionately represented in the survey.
Not A because it risks too many or too few graduate students. It is not C because again, it risks too many or too few graduate students. It is not D because each section has about 50 students and the professor only wants 30 in his sample.
