R↔S tangent to circle A and circle B at points R and S.
Prove:
AR ∥ BS
Answers
The proof is shown below:
What is tangent?The tangent is defined as a line touching circles or an ellipse at only one point.
As, tangent line is perpendicular to radius of the circle.
So,
AR ⊥ RS
BS ⊥ RS
Thus, AR and BS ⊥ to same line RS.
Now, either AR or BS are in same line or parallel.
since, they are the radius of different circles.
Hence, AR ║BS.

A furniture rental store charges a down-payment of $100 and $72.50 per month for a table. Hilde paid $535 to rent the table. Solve 72.50n + 100 = 535 to find the number of months Hilde rented the table.
Answers
Answer:
6 months
Step-by-step explanation:
First, subtract 100 from both sides
72.50n + 100 = 535
72.50n = 435
Divide each side by 72.50
n = 6
So, Hilde rented the table for 6 months
The demand d for a company’s product at cost x is predicted by the function d(x) = 500 – 2x. The price p in dollars that the company can charge for the product is given by p(x) = x + 5. Use the formula Revenue = price × demand to find the revenue function for the product.
R(x) = ________ + ________ x – _______ x^2
Answers
Answer:
-2x²+490x+2500
Step-by-step explanation:
Given that,
Demand, D(x) = 500-2x
The price for the product, P(x) = x+5
We need to find the revenue for the product. The formula for the revenue is given by :
Revenue = price × demand
Substitute all the values,
R = (x+5)(500-2x)
= 500x -2x² + 2500 -10x
= -2x²+490x+2500
So, the expression for the revenue function is "-2x²+490x+2500".

Good luck
The division of the number 405 in the ratio 4:11 is 297 and 108 respectively.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that the ratio is 4:11. the number is 405 which has to be divided by the ratio.
Let the common ratio between the numbers is x. Form an equation and solve for x.
4x + 11x = 405
15x = 405
x = 405 / 15
x = 27
The numbers are,
4x = ( 4 x 27 ) = 108
11x = ( 11 x 27 ) = 297
Therefore, the division of the number 405 in the ratio 4:11 is 297 and 108 respectively.

inches of snow on the ground.
The forecast for Monday is a 50% chance of 2.5 inches of snow. If it doesn't snow, 1.5 inches of snow will melt.
The forecast for Tueſday is a 50% chance of 1.5 inches of snow. If it doesn't snow, 0.5 inches of snow will melt.

graph the probability distribution for all possible values of X.
Answers
Answer:
All probablities are 0.25
Step-by-step explanation:
Got it right on Khan
From the given question, we can see that there is currently ten inches of snow.
With this in mind, we can see that the weather forecast for Monday is 50% probability for 2.5 inches of snow which is 1/2 for 2.5 inches of snow.
Furthermore, if it does not snow, then there would be 2.5-1.5= 1.0 inches of snow
Additionally, the weather forecast for Tuesday is 50% probability for 1.5 inches of snow which is 1/2 for 2.5 inches of snow.
Furthermore, if it does not snow, then there would be 1.5-0.5= 1.0 inches of snow
Given that the weather on Monday and Tuesday are independent events, then all the probabilities would be 1/2:1 which would be 0.5 inches of snow.
With this in mind, all the probabilities for chances of snow is 0.25
Therefore, we can see that all the possible values of x would be 0.25
