A. (-1, 1)
b. (2, 7)
c. (1, -1)
hope this helps :)
The mistakes that were made regarding the transformation are:
- He applied the reflection to the pre-image first.
- He used an incorrect angle of rotation around point P
<h3>How to illustrate the information?</h3>
It should be noted that a transformation simply means the changing of the position of an object
In this case, the transformation is incorrect as he applied the reflection to the pre-image first and used an incorrect angle of rotation around point P.

Obtuse scalene; there is no such thing as a right scalene or obtuse equilateral
Line is Passing through the Points (-3 , -1) and (-5 , 4)
Slope of a Line Passing through two points (x₁ , y₁) and (x₂ , y₂) is given by :
here x₁ = -3 and x₂ = -5 and y₁ = -1 and y₂ = 4
Answer:
404 cm³ Anyway... Look down here for my explanation.
Step-by-step explanation:
Let's Draw a line from the center of the circle to one of the ends of the chord (water surface) and another to the point at greatest depth on your paper. A right-angled triangle is formed too. The Length of side to the water-surface is 5 cm, the hospot is 7 cm.
We Calculate the angle θ in the corner of the right-angled triangle by: cos θ = 5/7 ⇒ θ = cos ˉ¹ (5/7)
44.4°, so the angle subtended at the center of the circle by the water surface is roughly 88.8°
The area shaded will then be the area of the sector minus the area of the triangle above the water in your diagram.
Shaded area 88.8/360*area of circle - ½*7*788.8°
= 88.8/360*π*7² - 24.5*sin 88.8°
13.5 cm²
(using area of ∆ = ½.a.b.sin C for the triangle)
Volume of water = cross-sectional area * length
13.5 * 30 cm³
404 cm³
