Answer:

When rotating a point 180 degrees counterclockwise about the origin our point A(x,y) becomes A'(-x,-y). So all we do is make both x and y negative.

A(x,y)\Rightarrow A^{\prime}(-x,-y)

The coordinates are given below as

S(-1,3),T(-4,3),U(-3,1)

By applying the rule, we will have

\begin{gathered} S(-1,3)\Rightarrow S^{\prime}(-(-1),(-3)\Rightarrow S^{\prime}(1,-3) \\ T(-4,3)\Rightarrow T^{\prime}(-(-4),-3)\Rightarrow T^{\prime}(4,-3) \\ U(-3,1)\Rightarrow U^{\prime}(-(-3),-1)\Rightarrow U^{\prime}(3,-1) \end{gathered}

By graphing the triangle, we Will have

stepladder [879]

Answer:

50

Step-by-step explanation:

The sum of the angles of a triangle add to 180 degrees

A + B + C = 180

2x-10 + 70+ x+30 = 180

Combine like terms

3x +90 = 180

Subtract 90 from each side

3x+90-90=180-90

3x= 90

Divide by 3

3x/3= 90/3

x=30

We want to find angle A

A = 2x-10

   =2*30 -10

  =60-10

  50

Which situation can be modeled by the inequality 50 - 12x &gt; 8?
eduard

Answer:

Option D.

Step-by-step explanation:

Borrowed $50 from your cousin. You pay him $8 and must pay him back within 12 weeks.

Let x be the amount paid on each week.

50-8\leq 12x

50-12x\leq 8

You can buy bags of pretzels in packages of 12. You $50 to spend, but want to have at least $8 left.

Let x be the amount of each package.

50-12x\geq 8

You owe your sister $50. You plan to pay her $12 a week till you owe her less than $8.

Let x be the amount paid on each week.

50-12x

You have $50 to spend on clothes, but you need to save at least $8 for bus fare. You plan to spend the rest on shirts that cost $12 each (including tax).

Let x be the number of shirts

50-12x>8

Therefore, the correct option is D.

Program: assign03a.m Write a MATLAB script file that uses principal (or amount), rate of interest, and time to compute and displ
DochEvi [55]

Answer:

The code is given in the answer along with the algorithm and explanation. The output and the workspace variables are also attached as screen shots.

Step-by-step explanation:

The basic algorithm of the code is as follows:

  1. Clear the workspace, command window and prepare the format as banking.
  2. Set the constant value of principal amount, this is fixed as 4000 in the code and can be changed.
  3. Ask the user to enter the value of lowest interest rate , highest interest rate , number of interest rate  values and number of years.
  4. Create the interest rate vector.
  5. For each entry of the interest rate vector, calculate the interest.
  6. Display the each entry of interest rate and the simple calculated interest.
  7. Calculate the average rate of interest and the average interest and display them.

The code is here as follows

%% Preparing the formats

clc,clear all;%Clearing command line and workspace

format bank%Formatting

format compact%Formatting

%% Setting the constants

PRINCIPAL = 4000;%Principal amount fixed as 4000.

%% Taking inputs from the user

low_val = input('Enter the low value for the rate range: ');%Lowest value of the interest

high_val = input('Enter the high value for the rate range: ');%Highest value of the interest

rate_vals = input('Enter the number of rate values including high and low values: '); %Total number of rate values

year = input('Enter number of years: ');% Number of years

%% Creating the interest vectors

rate = linspace(low_val,high_val,rate_vals);%Creating the vector

%% Initializing the array

simple_interest=zeros(length(rate),1);%initializing the array to hold the simple interest

%% Displaying the interest rate vectors

fprintf('\t\t Rate(%%)\t\tInterest($)\n');%Displaying the  interest rate and interest heading

%% Calculating the interest vectors

for i = 1:length(rate)

   simple_interest(i) = (rate(i)*year*PRINCIPAL)/100;%Calculating Simple rate of interest for a given rate over the principal amount

fprintf('\t\t %.2f\t\t\t%.2f\n',rate(i),simple_interest(i));% Displaying each entry  interest rate and interest

end

%% Calculating and printing the average interest

fprintf('Average: Rate(%%)\t\tInterest($)\n');%Displaying the heading for average rate and interest

fprintf('\t\t %.2f\t\t\t%.2f\n',mean(rate),mean(simple_interest));%Calculating and displaying the average interest.
