y - 10 = 110 ( x - 5)ii)
y = 110x -540 10 = 110(5) - 54010 = 550 - 54010 = 10Answer:
[tex]y=110x-540[/tex]
Step-by-step explanation:
Point-slope form of a linear equation: [tex]y-y_1=m(x-x_1)[/tex]
(where [tex]m[/tex] is the slope and [tex](x_1,y_1)[/tex] is a point on the line)
Given:
[tex]\textsf{slope } (m) = 110[/tex][tex](x_1,y_1)=(5,10)[/tex]Substitute these values into the equation:

You are shooting arrows at a target with three rings: there is a circle with 4 inch radius, a ring around it with 8 inch radius, and a ring around that with a 12 inch radius. If your 3 arrows will hit the target somewhere uniformly at random, what is the probability that you land exactly one shot in each of the three rings
The probability that you land exactly one shot in each of the three rings is 0.122
How to get the probability?
The probability of hitting each section will be the quotient between the area of the section and the total area of the target.
The area of the target is:
A = 3.14*(12 in)^2 = 452.16 in^2
The area for the smallest circle is:
A₁ = 3.14*(4 in)^2 = 50.24 in^2
So the probability of hitting the smallest circle is:
p₁ = A₁/A = (50.24/452.16) = 0.11
For the first ring, the area is:
A₂ = 3.14*(8in)^2 - 50.24 in^2 = 150.72 in^2
So the probability of hitting this ring is:
p₂ = (150.72)/(452.16) = 0.33
The probability of hitting the final ring is 1 minus the probabilities of hitting the two other regions, so we have:
p₃ = 1 - 0.11 - 0.33 = 0.56
The joint probability of hitting one arrow in each region, is given by the product between the individual probabilities for each region times the permutations (the permutations for 3 arrows are 3! = 3*2*1 = 6)
So the probability is:
P = 0.11*0.33*0.56*6 = 0.122

An incident ray strikes a boundary at a 72. 5-degree angle, resulting in an angle of refraction of 39. 6 degrees. The index of refraction of the first medium is 1. 3. What is medium 1? What is medium 2?.
Refractive index is the ratio of sin(i) to sin (r). Medium 2 is sodium chloride with a refractive index of 1.54.
What is Refractive Index?A material's refractive index (sometimes called refraction index or index of refraction) is a dimensionless quantity that specifies how quickly light passes through it.
As we know that the Refractive index is the ratio of sin(i) to sin (r), and it can be represented as,
[tex]\rm Refractive\ Index = \dfrac{Sin(i)}{Sin(r)}[/tex]
where
i is the incident angle and
r is the refraction angle.
Now, the refractive index can be written as for the given medium can be written as,
[tex]\rm Refractive\ Index = \dfrac{Sin(i)}{Sin(r)}\\\\[/tex]
[tex]\rm Refractive\ Index = \dfrac{Sin(79.5)}{Sin(39.6)}=1.542[/tex]
Now, if we take the ratio of the refractive index of the two mediums, then
[tex]\rm 1.542 = \dfrac{n}{1.0003}\\\\n = 1.542 \times 1.0003\\\\n= 1.5425\ \approx 1.54[/tex]
Hence, Medium 2 is sodium chloride with a refractive index of 1.54.

Answer:
A number line going from 2 to 7. A solid circle is at 4. Everything to the left of the circle is shaded.
Step-by-step explanation:
The pizza itself will cost $12, and because toppings cost $2 apiece, the maximum amount of toppings that can be used is 4.
4·2=8
8+12=20

Find Distance (4,6) (-4,-3)
Answer:
[tex]\sqrt{145}[/tex]
Step-by-step explanation:
The distance formula states that the distance between two points [tex](a,b)[/tex] and [tex](c,d)[/tex] is [tex]\sqrt{(a-c)^2+(b-d)^2}[/tex].
The two points we have are [tex](4,6)[/tex] and [tex](-4,-3)[/tex]. Plugging these numbers into the distance formula, we have
[tex]\sqrt{(4-(-4))^2+(6-(-3))^2[/tex].
Simplifying with order of operations, first using the distributive property, gives
[tex]\sqrt{(4+4)^2+(6+3)^2[/tex].
Squaring and adding gives
[tex]\sqrt{(4+4)^2+(6+3)^2}=\sqrt{8^2+9^2}\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~=\sqrt{64+81}\\~~~~~~~~~~~~~~~~~~~~~~~~~~~~=\boxed{\sqrt{145}},[/tex]
