What Are The Answers To Both Of The Questions

Answers

Answer 1

Answer:

see explanation

Step-by-step explanation:

(1)

f(x) = g(x) , that is

- x² + 3x - 2 = - x + 1 ( add x to both sides )

- x² + 4x - 2 = 1 ( subtract 1 from both sides )

- x² + 4x - 3 = 0 ( multiply through by - 1 )

x² - 4x + 3 = 0 ← in standard form

(x - 1)(x - 3) = 0 ← in factored form

equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

x - 3 = 0 ⇒ x = 3

(2)

let x and y be the 2 numbers : x > y , then

x + y = 217 → (1)

x - y = 85 → (2)

add the 2 equations term by term to eliminate y

2x + 0 = 302

2x = 302 ( divide both sides by 2 )

x = 151

substitute x = 151 into (1)

151 + y = 217 ( subtract 151 from both sides )

y = 66

the 2 numbers are 66, 151

A square has a side length of 22 meters.
What is the area of this square

Answers

Answer:

484 meters squared

Step-by-step explanation:

Area is Length times Width.

You're dealing with a square meaning all sides are equal.


You simply need to do 22m x 22m = 484m squared

The area is 484 because Area= L*W(length times width.

If two angles are complementary and one of the angles measures 27°, what does the other angle measure?

73°
153°
63°
27°

Answers

Okay, so, two angles are called complementary when their measures add to 90 degrees. So I think you would have to subtract 90 from 27 and you get your other angle. So, your answer would be 63 degrees.


Find the domain of the rational function below.

f(x)=(x+2)(x-1)/(x-3)(x+2)

Answers

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 }

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​

Answers

The amount of each monthly installment is $1,294 and the hire purchase of the car​ is: $4,158.

Monthly installement

a.  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

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

lesson 10.2 area of composite figures worksheet assigment

Answers

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.

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?

Answers

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.

To find:

Slope of the line

Solution:-

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.
