Answer:

x-intercept: (8,0)

Step-by-step explanation:

Given: f(x)=x^2-16x+64

For x-intercept, Put y=0 and solve for x.

x-intercept: It is a point where y-coordinate zero.

x^2-16x+64=0

x^2-8x-8x+64=0

(x-8)(x-8)=0

Equate each factor to 0 and solve for x

x-8 = 0    , x-8 = 0

x=8,8

x-intercept: (8,0)

Hence, The x-intercept is 8.

X=8 

Explanation: 
f(x)=x^2-16x+64+(x-8)^2

You see there is a double x- intercept by the 8. So the parabola is tangent to the x axis. So x=8 f(x)=0 

hope this helps <span />

Answer:

  48°

Step-by-step explanation:

ΔACB is isosceles, so angles A and B have the same measure. The measure of angle C in that triangle is ...

  ∠C = 180° -2(69°) = 42°

Angle C in ΔCDE has the same measure. Angle D is the complement of that:

  ∠D = 90° -42° = 48°

_____

The relations we used are ...

  • the sum of angles in a triangle is 180°
  • base angles of an isosceles triangle are congruent
  • vertical angles are congruent
  • acute angles in a right triangle are complementary

(x - h)^2 + (y - k)^2 = r^2

h = -2
k = -2
r = 6

(x - (-2))^2 + (y - (-2))^2 = 6^2

(x + 2)^2 + (y + 2)^2 = 6^2

(x + 2)^2 + (y + 2)^2 = 36. your answer

hope this helped, blessings! :)
