B(5,1) I’m smart and don’t worry the answer is correct
Answer:
(x - 7)² + (y - 3)² = 5
Step-by-step explanation:
The center (h , k) is the midpoint of two end points of diameter
h = (9 + 5) / 2 = 7
k = (4 + 2) / 2 = 3
Equation of circle: (x - h)² + (y - k)² = r²
r = (√(9 - 5)² + (4 - 2)²) / 2 = √5
Equation: (x - 7)² + (y - 3)² = 5
Answer:
y =
x + 5
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
f(x) = - 2x + 1 ← is in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
=
, then
y =
x + c
the line crosses the y- axis at (0, 5 ) ⇒ c = 5
y =
x + 5 ← equation of perpendicular line
convert all to a common ratio
24 1/6
30 3/6
36 2/6
(24+30+30+30+36+36)/6
186/6
the expected value is 31.
The second one: 4 times 10 to the power of 12
