The equation of this line in slope intercept form is y = 1.5x + 13.
What is slope intercept form?The slope-intercept form of a straight line is used to find the equation of a line. For the slope-intercept formula, we have to know the slope of the line and the intercept cut by the line with the y-axis.
Equation of line: y = mx + c
where m is slope of line and c is the y intercept.
[tex]\frac{y+2}{x+10} = \frac{3}{2}\\ \\ 2(y+2) = 3(x+10)\\\\2y + 4 = 3x + 30\\\\2y = 3x + 26\\\\y = 1.5x + 13\\\\where\ slope = 1.5\ and\ y\ intercept\ is\ (0,13)[/tex].

Find the radius of a circle using the Pythagorean theorem, given that the center is at (1, 5) and the point (5, 1) lies on the circle. 32−−√ units 12−−√ units 72−−√ units 50−−√ units
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.

Is it possible for a logarithm to equal a negative number and why?
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.
What is logarithm?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.

Read the excerpt from Team Moon.
The heavier the spacecraft, the harder it is to launch. And fuel is heavy. So it was critical to pinpoint the fuel needed, add a cushion, then take no more than necessary. But now, because the landing was taking far longer than planned, the fuel was almost gone. Mission Control wanted Neil to take as much time as he needed and fly the LM as near empty as possible only because they wanted him to make the landing. But if he ran out of fuel above the surface, in all likelihood the LM would crash onto the moon. So they were trying to time it to the last possible second before calling an abort—calling off the landing.

4 Doug has been wondering where the 24 hours in a day goes. On Monday, he spent of the day sleeping, 3 of the day in school, and of the day at soccer practice. How much time was left for other activities?
Answer:
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
Sara earns a weekly salary of $400 plus commission of 6.5% on sales at the clothing store where she works. How much would she earn in one week if she sold $1200 worth of merchandise? Sara would earn $______ for that week.
Answer: Sara would earn $478 for that week
Step-by-step explanation:
1. Sara's weekly salaries is $400, and she gets 6.5% on sales at her work.
2. In order to find how much she would get from the commission of $1200 worth of merchandise they sold, we need to find the 6.5% of 1200
Step 1: Our output value is 1200.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above, 1200=100%.
Step 4: Similarly, x=6.5%.
Step 5: This results in a pair of simple equations:
1200=100%(1).
x=6.5%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both equations have the same unit (%); we have
[tex]\frac{1200}{x} = \frac{100}{6.5}[/tex]
Step 7: Again, the reciprocal of both sides gives
[tex]\frac{x}{1200} =\frac{6.5}{100}[/tex]
⇒[tex]x=78[/tex]
Therefore, 6.5% of $1200 is $78
3. you would then need to add 400 + 78 and you get a total of $478

1 (-2,2) Write the equation, in point-slope form, of the line that is perpendicular to the given line and passes through the point (-2, 2). * (4 Points)
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

You mean like graph? Yeah.
Write in Function form
[tex]\frac{y-3}{x-6}=2\\y-3=2(x-6)\\y=2(x-6)+3\\y=2x-12+3\\y=2x-9[/tex]
So (y-3/x-6)=2 does represent "line"
[tex]\frac{y-6}{x-4}=5[/tex]
multiply x-4 all side.
[tex]y-6=5(x-4)[/tex]
Notice how the equation is similar to "Tangent" so it's clearly a line.
About reasoning, No idea how to explain but this might help...
Whenever you get rid of the fraction part, it'll leave only y-f(a)=f'(a)(x-a) which is a Tangent Line (It explains it.)
And when you simplify in Function Form, you'll get an exact linear function "[tex]y=mx+b[/tex]"

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