Given :

Center of circle, C = ( 1 , 5 )

Point on circle, P = ( 5 , 1 )

To Find :

The radius of a circle.

Solution :

We know, radius of circle is the distance between center and point of circle.

Distance between two points A(p,q) and B(r,s) is given by :

[tex]D = \sqrt{(p-r)^2+(q-s)^2}[/tex]

So, distance between the points (1, 5) and (5, 1) is :

[tex]D = \sqrt{(1-5)^2+(5-1)^2}\\\\D = 5.66 \ units[/tex]

Therefore, radius of circle is 5.66 units.

Hence, this is the required solution.

Answer:

Step-by-step explanation:

we will use ratio

magazines : cost

4 : $15

16 : $60

we will multiply 4 by 4 and 15 also by 4 so 16 magazines will cost $60

The cost of 16 magazines is $22.5.

Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.

Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.

Isabel bought 4 magazines for a total of $15.

The unit rate of the magazines,

= 15/4 = $3.75.

The cost of 16 magazines,

= 6 x 3.75

= $22.5

Therefore, the cost is $22.5.

Step-by-step explanation:

Given expression:

     2x - y + 3  = 0

The co-ordinates of the points at which the line intersects the coordinate axes is unknown?

Now,

     2x - y + 3 = 0

 Let us rearrange the equation;

        -y = -2x - 3

Multiply through by (-1);

        y = 2x + 3

the point where the line intercept the y- axis, x = 0

  so,

          y = 2(0) + 3  = 3

Coordinates  = (0,3)

the point where the line intercepts the x-axis, y = 0;

       0 = 2x + 3

      2x  = -3

       x  = [tex]\frac{-3}{2}[/tex]

Coordinates  = ([tex]\frac{-3}{2}[/tex] , 0)

Time left for other activities = 7/24 hours

Step-by-step explanation:

The complete question is "Sam has been wondering where the 24 hours in a day goes. On Monday, he spent 1/3 of the day sleeping, 1/4 of the day in school, and 1/8 of the day at soccer practice. How much time was left for other activities?"

Spent 1/3 of the day sleeping,

Spent 1/4 of the day in school

Spent 1/8 of the day at soccer practice.

Time consumed for all these activities = (1/3+1/4+1/8)

Time consumed for all these activities = (8+6+3)/24

Time consumed for all these activities = 17/24

Time left for other activities = (1 - 17)/24

Time left for other activities = (24-17)/24

Time left for other activities = 7/24

If we know that [tex]x = 1[/tex] and [tex]y = 9[/tex], the value of [tex]g[/tex] is 19.

Step-by-step explanation:

Let [tex]C(x,y) =(-2,12)[/tex] and [tex]D(x,y) =(4,6)[/tex], from Analytical Geometry and Linear Algebra we have that midpoint of CD is determined by:

[tex]M(x,y) = \frac{1}{2}\cdot C(x,y)+\frac{1}{2}\cdot D(x,y)[/tex] (Eq. 1)

[tex]M(x,y) = \frac{1}{2}\cdot (-2,12)+\frac{1}{2}\cdot (4,6)[/tex]

[tex]M(x,y) = (-1,6)+(2,3)[/tex]

[tex]M(x,y) =(-1+2,6+3)[/tex]

[tex]M(x,y)= (1,9)[/tex]

The only numbers you can plug into a logarithm are positive numbers not equal to 1. Negative numbers, and the number 0, aren’t acceptable arguments to plug into a logarithm, but why?

The reason has more to do with the base of the logarithm than with the argument of the logarithm. To understand why, we have to understand that logarithms are actually exponents. The base of a logarithm is also the base of a power function.

When you have a power function with base 0, the result of that power function is always going to be 0. In other words, there’s no exponent you can put on 0 that won’t give you back a value of 0. Or, put a different way, 0 raised to anything is always still 0. In the same way, 1 raised to anything is always still 1.

If you raise a negative number to a positive number that’s not an integer, but instead a fraction or a decimal, you might end up with a negative number underneath a square root. And as you know, unless we’re getting into imaginary numbers, we can’t deal with a negative number underneath a square root.

So 0, 1, and every negative number presents a potential problem as the base of a power function. And if those numbers can’t reliably be the base of a power function, then they also can’t reliably be the base of a logarithm.

For that reason, we only allow positive numbers other than 1 as the base of the logarithm. Then what we know is that, if the base of our power function is positive, it doesn’t matter what exponent we put on that base (it could be a positive number, a negative number, of 0), that power function is going to come out as a positive number.

So in summary, because the base can only be a positive number, that means the argument of the logarithm can only be a positive number. Which means that in order to protect our bases, we have to only allow positive arguments inside the logarithm.

Hope this helps!

No ,it is  not possible for a logarithm to equal a negative number.

A logarithmic is the power to which a number must be raised in order to get some other number.

For example, the logarithm base b of a number n is the number x that when b is raised to [tex]x^{th}[/tex] power, the resulting value in n i.e.

[tex]log_{b}n = x[/tex]  ⇔ [tex]b^{x} =n[/tex]

No, it is possible for a logarithm to equal a negative number because  logarithm function [tex]log_{a}(b) = n[/tex] is the inverse of the exponent function [tex]a^{n} =b[/tex] where the base a>0. Since, the base a raised to any exponent n is positive, the number b must be positive.

The logarithm of a negative number b is undefined.  

Hence, it is not possible for a logarithm to equal a negative number.

Answer:

y = -5x - 8

Step-by-step explanation:

Take the points (-5,-4) and (0,-3) plug them into this formula to get the slope.

[tex]\frac{y2 - y1 }{x2 - x1}[/tex]

Now plug in your points

[tex]\frac{-3 - (-4)}{0 - (-5)} \\\\\frac{1}{5}[/tex]

Since you're slope is 1/5 the slope of the perpendicular line is going to be the totally opposite -5 is the slope of the perpendicular line.

Now plug in -5 and the point (-2,2) into y = mx + b to get the y-intercept

2 = -5(-2) + b (b represents the y-intercept)

2 = 10 + b (subtract 10 from both sides)

-8 = b

The perpendicular line looks like this y = -5x - 8
