The value of angle APA' is 90°.
What is geometric transformation?It is defined as the change in coordinates and the shape of the geometrical body. It is also referred to as a two-dimensional transformation. In the geometric transformation, changes in the geometry can be possible by rotation, translation, reflection, and glide translation.
We have a point 'p' which is a fixed point.
Triangle ABC is rotated about the 'p' point such that the new location of A, B, and C becomes A', B', and C'.
The new triangle formed is triangle A'B'C'.
From the figure, we can clearly see that the angle APA' is a right-angle triangle.
m∠APA' = 90°
Thus, the value of angle APA' is 90°.

Answer:
Step-by-step explanation:
1. a). Hypotenuse² = (Leg 1)² + (Leg 2)²
h² = 10² + 24²
h = √676
h = 26
(b). Hypotenuse² = (Leg 1)² + (Leg 2)²
(25)² = (15)² + (leg 2)²
Leg 2 = √(625 - 225)
= √400
= 20
(c). Hypotenuse² = (Leg 1)² + (Leg 2)²
h² = 4² + 6²
h = √(16 + 36)
h = √52
h = 2√13
(d). Hypotenuse² = (Leg 1)² + (Leg 2)²
(14)² = (Leg 1)² + 7²
Leg 1 = √(196 - 49)
= √147
= 7√3
2). Hypotenuse² = (Leg 1)² + (Leg 2)²
Leg 1 = leg 2 = 7 units [Since, triangle is an isosceles triangle]
h² = 7² + 7²
h = √98
h = 7√2
Option (1) is the correct option.
3). Hypotenuse² = (Leg 1)² + (Leg 2)²
(26)² = (Leg 1)² + (10)²
Leg 1 = √(676 - 100) = 24
Area of a right triangle = [tex]\frac{1}{2}(\text{Leg 1})(\text{Leg 2})[/tex]
= [tex]\frac{1}{2}(24)(10)[/tex]
= 120 square units
Option (3) is the correct option.

PAGE 4 (SCREENSHOT)
Step-by-step explanation:
PAGE 1
16.) C b/c if you draw a line through it you have line of symmetry and a regular hexagon has rotational symmetry.
PAGE 2
11.) P(6, 2) ----(6*3, 2*3) -----> P'(18, 6)
So e is the answer
12.) The compound transformation should read
Dilation with center at origin and scale factor of 1/2
Reflection across the x-axis
Reflection across the x-axis rule is (x, y) -->(x, -y)
a is the answer b/c A(-1, -2) --> A'(-1/2, -1) --> (-1/2, 1)
PAGE 3
13.) The scale of the dilation is 1/4 b/c ---> 25*1/4 = 6.25 and 64*1/4 = 16
So 16*1/4 = 4 and 10*1/4 = 2.5, so e is the answer
14.) Dilation b/c you can either enlarge or reduce the pre-image.
15.) A heptagon has 7 lines of symmetry b/c it is equal to the number of sides

Find the value of x
Please show work thank you
Answer:
92
Step-by-step explanation:
In a graph, x represents the number of months since a
business opened, and y represents the total amount of
money the business has earned. The following three
points are from the graph:
(2, 1990) (5, 4225) (9, 7205)
Find the slope and y-intercept. Explain what each
represents.
Answer:
My answer: To find the Slope the first we would need to use is the Slope-Intercept Formula. Y=mx+b. So 7205-4225=2980 and 9-5=4 So then you have to divide 2980/4=745 So the slope is 745. To find the Y-Intercept (b) we need to use the formula again. 4225= 745(5)+b so 745x5=3725 so we subtract on both sides 3725 is cancelled so 4225-3725=500 So the y-intercept is 500
Sample Response: The slope of this scenario is 745. The slope represents the profit made each month.
Step-by-step explanation:
The two answers above are right.

f(x)= √x+3. Find the inverse of f(x) and it's domain
Step-by-step explanation:
f(x) = √x + 3
y = √x + 3
√x = y - 3
x = (y - 3)²
Hence inverse of f(x) = (x - 3)² and its domain is x >= 3.
The required domain of the inverse function F(x)= (x-3)^2 is given by ≥3
f(x)= √x+3
What is inverse function?The inverse function can be defined as the transverse of function.
F(x) = y
y = √x + 3
x= (y - 3)^2
or
for inverse function
F(x) = (x-3)^2
The domain of function is given by greater and equal to 3
The required inverse function is F(x) = (x-3)^2 and its domain is greater and equal to 3.

The solution to the given expression [tex]\frac{7}{5} \times ({\frac{1}{4} \div \frac{7}{4} }) \times (-10)[/tex] is -2. Option (C) of all is correct.
Mathematically, an expression is a combination of numbers, variables, operations, and functions that are combined according to specific rules to represent a mathematical computation or relationship. It can be thought of as a mathematical phrase or formula.
To evaluate the expression [tex]\frac{7}{5} \times ({\frac{1}{4} \div \frac{7}{4} }) \times (-10)[/tex] , we follow the order of operations (PEMDAS/BODMAS), which dictates that we perform the division first, then the multiplication.
Division: [tex]\frac{1}{4}[/tex] ÷ [tex]\frac{7}{4}[/tex] can be rewritten as [tex]\frac{1}{4} \times \frac{4}{7}[/tex] since division is equivalent to multiplying by the reciprocal.
[tex]\frac{1}{4} \times \frac{4}{7}[/tex] = [tex]\frac{1}{7}[/tex]
Multiplication: Now we can multiply the fractions and the remaining number.
[tex]\frac{7}{5} \times \frac{1}{7} \times (-10)[/tex] = [tex]\frac{-70}{35}[/tex]
= -2.
Therefore, the value of the expression [tex]\frac{7}{5} \times ({\frac{1}{4} \div \frac{7}{4} }) \times (-10)[/tex] is -2.
