Answer:
join the two points
Step-by-step explanation:
(x,y) = (1,3)
(just by substituting the number into the equation to make it fit)
then, also draw a point at (0.-1)
Circumference of a circle is found with the equation
C = 2 × pi × r
where r is the radius. So for your problem...
C = 2 × 3.14 × 4
C = 25.12 meters
Answer:
y = - 3x - 2
Step-by-step explanation:
The function is linear and can be expressed in slope- intercept form
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (- 2, 4) and (x₂, y₂ ) = (- 1, 1) ← 2 ordered pairs from the table
m =
=
=
= - 3 , then
y = - 3x + c
To find c substitute any ordered pair into the equation
using (0, - 2 ) , then
- 2 = - 3(0) + c = 0 + c ⇒ c = - 2
y = - 3x - 2 ← function rule
Answer:
C. 726 in^2.
Step-by-step explanation:
Each face has area 11^2 = 121 in^2 ( because each face is a square).
There are 6 faces so the total surface area = 6 * 121
= 726 in^2.
