Step-by-step explanation:
Let's say the coordinates of Q are (h, k).
The slope of PQ is perpendicular to the tangent line.
(k − 2) / (h − 2) = -⅓
3(k − 2) = -(h − 2)
3(k − 2) = 2 − h
Solving for h:
h = 2 − 3(k − 2)
h = 2 − 3k + 6
h = 8 − 3k
(2, 2) is a point on the circle, so:
(2 − h)² + (2 − k)² = r²
Substituting:
9 (k − 2)² + (2 − k)² = r²
10 (k − 2)² = r²
The equation of the circle is:
(x − 8 + 3k)² + (y − k)² = 10 (k − 2)²
Without more information, there are an infinite number of possible solutions. For example, if k = 1, the equation of the circle is:
(x − 5)² + (y − 1)² = 10
Answer: The answer is 60 cents
Step-by-step explanation: the way to find this answer is to add 10x3 then add 5 to that then add 25 in the end and you get 60 cents. Hope this helped!
Answer:
Unemployment (August) = 35'222/634'512 ≈ 0.0555 ≈ 5.55%
Employed (August) = 634'512-35'222 = 599'290
Labor force (September) = 634'512-156'518 = 477'994
Employed (September) = 599'290-206'024 = 393'266
Unemployed (September) = 477'994-393'266 = 84'728
Unemployment (September) = 84'728/477'994 ≈ 0.177 ≈ 17.7%
Step-by-step explanation:
The cab rate model for Fwam will be given as y=2.8x+4.
<h3>What is an equation?</h3>
It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
Here we have an equation model for Lamonte y=2.2x+2.5 here y is the total cost and x is the distance in miles.
So here Fwam charges a $4 pick up fee and $2.80 per mile. The equation model will be:-
y=2.8x+4.
Hence cab rate model for Fwam will be given as y=2.8x+4.
