r = radius
Arc length = 2(3.14)r
7.9 cm = r
Plug our values in
Arc length = 2(3.14)(7.9 cm)
Arc length = 49.6 cm
Answer: (-5,0)
Step-by-step explanation:
-4x + 5y = 20 the x intercept is when y is zero so input zero into the equation and solve for x.
-4x + 5(0) = 20
-4x = 20
x = -5
Pretty sure the answer is C since the point is at 1 on the c-axis
Step 1
Given;

Required; To find the center that eliminates the linear terms
Step 2



Step 3
Substitute a,d,e into the vertex form


Step 4
Completing the square for -y²+4y



Step 5
Substitute a,d,e into the vertex form

Step 6

Step 7

Hence the answer is (-3,2)
