The line l is tangent to the circle with equation x^2 + y^2=10 at the point P.
Determine the equation of line l.
Given:
The equation of a circle is
[tex]x^2+y^2=10[/tex]
A tangent line l to the circle touches the circle at point P(1,3).
To find:
The equation of the line l.
Solution:
Slope formula: If a line passes through two points, then the slope of the line is
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
Endpoints of the radius are O(0,0) and P(1,3). So, the slope of radius is
[tex]m_1=\dfrac{3-0}{1-0}[/tex]
[tex]m_1=\dfrac{3}{1}[/tex]
[tex]m=3[/tex]
We know that the radius of a circle is always perpendicular to the tangent at the point of tangency.
Product of slopes of two perpendicular lines is always -1.
Let the slope of tangent line l is m. Then, the product of slopes of line l and radius is -1.
[tex]m\times m_1=-1[/tex]
[tex]m\times 3=-1[/tex]
[tex]m=-\dfrac{1}{3}[/tex]
The slope of line l is [tex]-\dfrac{1}{3}[/tex] and it passs through the point P(1,3). So, the equation of line l is
[tex]y-y_1=m(x-x_1)[/tex]
[tex]y-3=-\dfrac{1}{3}(x-1)[/tex]
[tex]y-3=-\dfrac{1}{3}(x)+\dfrac{1}{3}[/tex]
Adding 3 on both sides, we get
[tex]y=-\dfrac{1}{3}x+\dfrac{1}{3}+3[/tex]
[tex]y=-\dfrac{1}{3}x+\dfrac{1+9}{3}[/tex]
[tex]y=-\dfrac{1}{3}x+\dfrac{10}{3}[/tex]
Therefore, the equation of line l is [tex]y=-\dfrac{1}{3}x+\dfrac{10}{3}[/tex].

Answer:
y=2x-14
y=x-2
The slopes are not the same
Step-by-step explanation:
L1 3y=3x-6
Divide everything by 3 to isolate the y
y=x-2
L2 5y-10x=-70
add -10x to isolate the y
5y=10x-70
Divide everything by 5 to isolate the y
y=2x-14

A. 4 cm
B. 3 cm
C. 8 cm
D. 7 cm
Answer:
8cm
Step-by-step explanation:
circumference formula[tex]2\pi \: r[/tex]

50 = 6.28r
7.9 = r
8 = r
Multiplying by which number is equivalent to an increase 49.5%
Answer:
22.46
Step-by-step explanation:
'Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
49.5% = 49.5/100 = 49.5 ÷ 100 = 0.495.
100% = 100/100 = 100 ÷ 100 = 1.
Increase the number by 49.5% of its value.
Percentage increase = 49.5% × 22.46
New value = 22.46 + Percentage increase

For a regular polygon with 3 sides, each interior angle has a measure of-
A. 60
B.45
C.30
D.120
60
The sum of the interior angles of a triangle is 180
if there are 3 sides then there are 3 angles
180/3=60 so each interior angle has a measure of 60

34 < 6 + d
Solve the inequality
Answer:
28< 6
Step-by-step explanation:
34 < 6 + d
Subtract 6 from each side
34-6 < 6 + d-6
28< 6
Answer:
28<d
Step-by-step explanation:
Since all you need to do is find d, to do this do the inverse operation of 6 which is -6 and add them to both sides which gives you 28<d

What is 20% of 50 and what would 10% equal
Answer:
20/100 x 50 is 10
10% would be 10/100 is fraction form
I want to help you on the first thing you said,
so always consider a percent as a fraction but there denominator is ALWAYS 100 (a way to remember that is that the word "cent" means 100). The word "of" means multiplication so that means your multiplying it with 50 and just do the multiplication.
I'm really hoping you understand!

Tamara looked at the expression 35 + z < 59. She believes that z can equal more than one value.
Answer:
z<24
Step-by-step explanation:
It can't be more than one value. All you do is subtract 35 from both sides to isolate z.
Hope this helped!
Answer:
Tamara is correct here. With the expression: 35 + z < 59, Some examples could be; 10,20,15,21,22,23,24, or really anything under the number 24 will be acceptable for this expression to be true.
Step-by-step explanation:
Hope that this helps! :)
