There is a circle with the center [tex](6,-8)[/tex] and radius = [tex]20[/tex] units
We have to find whether the points given in the options will not lie inside the circle if the radius of the circle is halved.
"If a point lies inside the circle, distance between the center and the given point will be less than the radius of the circle".
To find the distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
Distance = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
If a point lies inside the circle with radius 10 units, distance between the point and the center will be less than 10 units.
Option A
Distance between the points [tex](-\frac{1}{20},0)[/tex] and [tex](6, -8)[/tex]
= [tex]\sqrt{(6+\frac{1}{20})^2+(-8-0)^2}[/tex]
= [tex]\sqrt{100.6025}[/tex]
= [tex]10.03[/tex] units
Since, [tex]10.03>10[/tex] units
Therefore, [tex](-\frac{1}{20},0)[/tex] will lie outside the circle.
Option B
Distance between [tex](\frac{1}{20},0)[/tex] and [tex](6,-8)[/tex] = [tex]\sqrt{(6-\frac{1}{20})^2+(-8-0)^2}[/tex]
= [tex]\sqrt{99.4025}[/tex]
= [tex]9.97[/tex] units
Since, [tex]9.97<10[/tex] units
Therefore, [tex](\frac{1}{20},0)[/tex] will lie inside the circle.
Option C
Distance between [tex](-\frac{1}{10},-6)[/tex] and [tex](6,-8)[/tex] = [tex]\sqrt{(6+\frac{1}{10})^2+(-6+8)^2}[/tex]
= [tex]\sqrt{41.21}[/tex]
= [tex]6.42[/tex] units
Since, [tex]6.42<10[/tex] units
Therefore, [tex](-\frac{1}{10},-6)[/tex] will lie inside the circle.
Option D
Distance between [tex](8,10)[/tex] and [tex](6,-8)[/tex] = [tex]\sqrt{(8-6)^2+(10+8)^2}[/tex]
= [tex]\sqrt{328}[/tex]
= [tex]18.11[/tex] units
Since, [tex]18.11>10[/tex] units
Therefore, [tex](8, 10)[/tex] will lie outside the circle.
Now we can conclude that [tex](-\frac{1}{20},0)[/tex] and [tex](8,10)[/tex] will lie outside the circle.
Options (A) and (D) will be the correct options.

Answer:
y = 5/6x + 4
Step-by-step explanation:
y = mx + b
b = 4 because when x = 0, y = 4
m = (y2 -y1) / (x2 - x1)
where two points on the equation are (x1, y1) & (x2, y2)
Let's pick points (6,9) & (-6,-1)
m = (-1 - 9) / (-6 - 6)
m = -10 / -12 = 5/6

Work out the value of angle x.
x
110%
Help:(
Answer:
40°
Step-by-step explanation:
Angles on a straight line add up to 180
180 - 110 = 70
As it's an isosceles triangle the opposite angles are the same
70 + 70 = 140
180 -140 = 40
Answer:
Step-by-step explanation:
180-110=70
x+70+70=180
x=180-140=40°

What are the 5 positive integers that have a mode of 2 and 4, a median of 4 and a mean of 5
Answer:
10 i belive
Step-by-step explanation:
Hence, the five positive integers are 2, 2, 4, 4, 13.
What is a mean , median and mode?Mean- The arithmetic mean of a given data is the sum of all observations divided by the number of observations.
Median-The value of the middlemost observation, obtained after arranging the data in ascending or descending order, is called the median of the data.
Mode-The value which appears most often in the given data i.e. the observation with the highest frequency is called a mode of data.
Step by Step Solution:According to the question , it can be concluded that the total no. of observations are 5.
So , Let n=5
Let the integers be a, b, c, d and e
The question says that mode(s) are 2 and 4.
This indicates that 2 and 4 both have occurred more than once , and both have same frequency since both are modes.
Since we have only 5 integers , and 2 and 4 both are modes , so both these numbers have possibility to occur only twice.
Hence , it becomes , a=2 , b=2 , c=4 , and d=4
Hence we can say that out of five required integers ,four of them are 2 and 4.
Further , we are given that mean is 5.
therefore , using formula:
Mean = Sum of Observations / Number of observations(n)
Mean= (a+b+c+d+e) / 5
5 = (2+2+4+4+e) / 5
5 = (12+e)/5
Multiplying both sides by 5 , we get :
25 = 12+e
e=25-12
Hence , e = 13
So, the five positive integers are 2, 2, 4, 4, 13.

Find the value of x. Your answer must be
Exact
Answer:
x = 8
Step-by-step explanation:
sin (30) = 4/x => solve for x.
Answer:
[tex]x=8[/tex]
Step-by-step explanation:
Use the sine ratio because we have the hypotenuse and side opposite the given angle to work with:
[tex]sineX=\frac{opposite}{hypotenuse}[/tex]
Insert the values:
[tex]sin30=\frac{4}{x}[/tex]
Multiply both sides by x:
[tex]x(sin30)=x(\frac{4}{x} )\\\\x*sin30=4[/tex]
Divide both sides by sin30°:
[tex]\frac{x*sin30}{sin30} =\frac{4}{sin30}\\\\x= \frac{4}{sin30}[/tex]
Insert the value of x into a calculator:
[tex]x=8[/tex]
OR:
The little red square means that angle is 90º, and the other given angle is 30°. Since every triangle has a measure of 180°, the other missing angle is 60°. The given triangle is a 30°-60°-90° triangle with the following rules:
[tex]long.leg=short.leg*\sqrt{3}\\\\hypotenuse=short.leg*2[/tex]
The hypotenuse is represented by the variable x. We are given the value of the short leg, which is 4. Solve for the hypotenuse:
[tex]h=4*2\\\\h=8[/tex]
Therefore, the value of x is 8.

what is the range of the function f(x)=7-3x when the domain is {-4, -2, 0, 2}?
Answer:
{19,13,7,1}
Step-by-step explanation:
Since the domain is the input we have to plug in each of those numbers to get the range ( or the output.) When we plug in -4 we get 19. When we plug in -2 we get 13, when we plug in 0 we get 7 and when we plug in 2 we get 1. (:
