Answer:
The other endpoint is (-33, 17)
Step-by-step explanation:
The rule of the mid-point of a segment whose endpoints are
([tex]x_{1}[/tex], [tex]y_{1}[/tex]) and ([tex]x_{2}[/tex], [tex]y_{2}[/tex]) is
[tex](x_{M},y_{M}) = (\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})[/tex]In our question
∵ The coordinates of the endpoints of a segment are (-15, 13) and (x, y)
∴ [tex]x_{1}[/tex] = -15 and [tex]x_{2}[/tex] = x
∴ [tex]y_{1}[/tex] = 13 and [tex]y_{2}[/tex] = y
∵ The coordinates of the mid-point of this segment are (-24, 15)
∴ [tex]x_{M}[/tex] = -24 and [tex]y_{M}[/tex] = 15
→ Use the rule of the mid-point to find x and y
∵ [tex]-24=\frac{-15+x}{2}[/tex]
→ Multiply both sides by 2
∴ -48 = -15 + x
→ Add 15 to both sides
∴ -33 = x
∵ [tex]15=\frac{13+y}{2}[/tex]
→ Multiply both sides by 2
∴ 30 = 13 + y
→ Subtract 13 from both sides
∴ 17 = y
∴ The other endpoint is (-33, 17)

An incident ray of light strikes water at an angle of 30°. The index of refraction of air is 1. 0003, and the index of refraction of water is 1. 33. What is the angle of refraction rounded to the nearest whole number? 22° 24° 30° 42°.
The measure of the angle of refraction is 22 degress, the correct option is A.
What is the angle of refraction?
The angle made by a refracted ray with a perpendicular to the refracting surface.
Given
An incident ray of light strikes water at an angle of 30°.
The index of refraction of air is 1. 0003, and the index of refraction of water is 1. 33.
In order to determine the angle of the refracted ray, we may apply Snell's law, which states that the ratio of the sines of the angles of incidence and refraction is constant for a given wave when it passes through two different media.
The angle of the refraction is given by;
[tex]\rm 1.0003 \times sin(30) = 1.33 \times sin(\phi)\\\\ \rm 1.0003 \times 0.5 = 1.33 \times sin(\phi)\\\\Sin\phi=\rm \dfrac{1.0003 \times 0.5 }{1.33}\\\\Sin\phi=0.37\\\\\phi = 22[/tex]
Hence, the measure of the angle of refraction is 22 degress.

Answer:
CD =7.5 AC =20
Step-by-step explanation: you can answer this question by creating a proportion. For the side AB, we can find the total length by adding AE and EB, for a total of 8. Now we can build a proportion, where x equals AC. 12.5/x= 5/8. When you build a proportion, it’s important to make sure you use the same corresponding parts in the same places, for example, in both the fractions we made for the proportion, the total side length was on the bottom. From this proportion, we now cross multiply to get 5x=100. Divide both sides by 5 and you get that the length of AC is 20. We can do the same with CD. The proportion you’d use to find CD would involve the smaller line segment over the total length of the line. This would look like so: x/20=3/8. Cross multiply again and you’d get 60=8x. Divide both sides by 8 and you’d get x=7.5. This means the length of CD is 7.5.

A farmer has 540 m of fencing to enclose a
rectangular area and divide it into two sections as
shown.
a) Write an equation to express the total area
enclosed as a function of the width.
b) Determine the domain and range of this area
function.
c) Determine the dimensions that give the
maximum area.
The dimensions that give the maximum area is 135 m by 135 m for a rectangular area with 540 m of fencing
What is an area?An area is the amount of space occupied by a two dimensional shape or object.
Let w represent the width and l represent the length, hence:
540 = 2(l + w)
l = w - 270
The area (A) is:
A = length * width
A = w(w - 270) = w² - 270w
The domain of the function is (270, ∞), the range is (0, ∞).
The maximum area is at dA/dw = 0, hence:
2w - 270 = 0
w = 135 m, l = 270 - w = 135 m
The dimensions that give the maximum area is 135 m by 135 m
