Yes, this particular one is a function because the inputs hace exactly one output.
Answer:
The perimeter of triangle PQR is 17 ft
Step-by-step explanation:
Consider the triangles PQR and STU
1. PQ ≅ ST = 4 ft (Given)
2. ∠PQR ≅ ∠STU (Given)
3. QR ≅ TU = 6 ft (Given)
Therefore, the two triangles are congruent by SAS postulate.
Now, from CPCTE, PR = SU. Therefore,

Now, side PR is given by plugging in 3 for 'y'.
PR = 3(3) - 2 = 9 - 2 = 7 ft
Now, perimeter of a triangle PQR is the sum of all of its sides.
Therefore, Perimeter = PQ + QR + PR
= (4 + 6 + 7) ft
= 17 ft
Hence, the perimeter of triangle PQR is 17 ft.
C = 2 pi r given r = 4
so
C = 2 pi (4)
C = 8 pi
answer
C. C = 8pi
Answer:
b must equal 7 and a second solution to the system must be located at (2, 5).
Step-by-step explanation:
Rearranging the first equation:
y = (x - 3)^2 + 4
From this we see that the vertex is at the point (3,4).
So one solution of equation 2 is (3 ,4).
Substituting in equation 2:
4 = -3 + b
b = 7.
So equation 2 is y = - x + 7.
Now we check if (2, 5) is on this line:
5 = -2 + 7 = 5 , therefore (2, 5) is on this line.
Verifying if (2, 5) is also on y = (x - 3)^2 + 4:
5 = (2 - 3)^2 + 4 = 1 + 4 = 5
- so it is. and a second solution to the system is (2, 5).
