Examine the following table that represents some points on a line.
Which equations in point-slope form represents this line?
y + 10 = 2(x + 6)
y + 9 = 1/2(x + 4)
y + 10 = 1/2(x + 6)
y + 4 = 1/2(x — 6)
y + 4 = 2 (x — 6)
y — 9 = 2(x — 4)
Answer:
Option (2), (3) and (4)
Step-by-step explanation:
Let the equation of the line representing the given table is,
y - y' = m(x - x')
where 'm' = slope of the line
(x', y') is the point lying on the line.
Let the two points (-6, -10) and (-4, -9) lie on the line
Slope 'm' = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
= [tex]\frac{-9+10}{-4+6}[/tex]
= [tex]\frac{1}{2}[/tex]
Equation of the line passing through (-4, -9) with slope [tex]\frac{1}{2}[/tex] will be
y - (-9) = [tex]\frac{1}{2}(x+4)[/tex]
y + 9 = [tex]\frac{1}{2}(x+4)[/tex]
Equation of the line passing through (-6, -10) with slope = [tex]\frac{1}{2}[/tex]
y - (-10) = [tex]\frac{1}{2}(x+6)[/tex]
y + 10 = [tex]\frac{1}{2}(x+6)[/tex]
Equation of the line passing through (6, -4) and slope = [tex]\frac{1}{2}[/tex]
y + 4 = [tex]\frac{1}{2}(x-6)[/tex]
Therefore, Options (2), (3) and (4) will be the answer.

What is quotient and product rule of logarithm?Logarithm, the exponent or power to which a base must be raised to yield a given number. The quotient rule says that, the logarithm of a quotient is equal to a difference & the product rule says that logarithm of product is equal to the sum of logarithm.
Formula to be used,
log〖(ab)=loga+logb 〗
〖log(〗〖a/b)=loga-logb 〗
here, we have,
the given equation is,
㏑[tex]e^{ln( x)}[/tex] + ㏑[tex]e^{ln (x^{2}) }[/tex] = 2㏑8
or, ㏑x * ㏑ e + ㏑x² * ㏑e = 2㏑ 8
or, ㏑x + ㏑x² = 2㏑ 8
or, ㏑( x*x²) = ㏑ 8²
or, ㏑x³ = ㏑ 64
now, taking out the nature logarithm from both sides, we get,
x³ = 64
or, x = 4
Hence, The solution is, the true solution to the equation below is x=4.

A wooden toy kit has different painted solids. One solid is a cylinder with a diameter of 2cm and a height of 14cm.
Q.What is the surface area of the cylinder? (Answer is 96cm^2, I know how to get it)
Q.One can of paint covers 40m^2. How many cylinders can be painted with one coat of paint? (Answer is about 4244, but the question is how do you get it?)
Answer:
Surface are = 94.24 cm2
Cylinders =4,244
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Surface area of a cylinder = 2π (diameter/2) h + 2π (diameter /2)²
Replacing with the values given
s = 2π (2/2) 14 + 2π (2/2)²
s = 87.96+ 6.28 =94.24 cm2
Since:
1 m2 = 10,000 cm2
40 m2 = 400,000 cm2 (area that one can of paint covers)
We have to divide the area that one can of paint covers by the surface area of each cylinder:
400,000/94.24 = 4244 cylinders

The ratio of angle measures is 1:2:2. Classify the triangle by its angle measures. obtuse triangle right triangle equiangular triangle acute triangle
Answer:
Acute Triangle
Step-by-step explanation:
Angles in a triangle add up to 180 degrees.
So,
x+2x+2x = 180
=> 5x = 180
Dividing both sides by 5
=> x = 36
So, The lengths are:
=> 36
=> 72
=> 72
Since all the angles are less than 90 degrees, It is an acute triangle.

which of the following equations is modeled by the graph.
a=5t
a=50t
a=50 + t
a=10t
Answer:
a = 50t
Step-by-step explanation:
The graph goes through (0,0) so the y intercept is 0
a=5t
a=50t
a=50 + t not it
a=10t
The slope is y/x since the y intercept is 0
m = 50/1 = 50
The equation for the line is
y = 50x+0
y = 50x
Using the variables given
a = 50t
