Answer:
11 inches
Step-by-step explanation:
Take the square root and add 3.
(x -3)² = 64
x -3 = √64 = 8
x = 8 +3 = 11
The original photo was 11 inches on a side.
It should be 75000 because of the 671 it should get rounded up
1)
You have to find the diameter, which is 2r
You can do it two ways
a) Find the radius first
r =
= √28,26/3,14 = √9 = 3 cm
d = 3*2 = 6 cm
b) Use the formula d =
= √4*26,28/3,14 = √113,04/3,14 = √36 = 6 cm
2)
Use the formula r =
So r = √12,56/3,14 = √4 = 2 cm
For questions 1-3, I'm not sure. So sorry :(
4) The length of the third side is √3. a^2 + 1^2 = 2^2
5) Quadrants 1 and 2 have positive sine values.
