The diameter is 12 units long. Their equation could be seen in y = 1, because it is a horizontal line. From x = - 7 to x = 0 is 7 units. From x = 0 to x = 5, is 5 units. 5 + 7 = 12. This means the radius is 6. We will use this later. If you need another way to find the radius, let me know. I can just use distance formula.
We will use these endpoints to find the center.
Midpoint =
=
=
= (- 1, 1)
This is the center.
The equation of a circle is (x - h)² + (y - k)² = radius² where (h, k) is the center.
Plug in our given information now.
(x + 1)² + (y - 1)² = 6²
(x + 1)² + (y - 1)² = 36 is your equation.
Answer:
15.14 cups is the answer, just do 5*3 then put the 14 into place it should be the answer
Answer:
y= -1
Step-by-step explanation:
multiply 1/2 and -8 to get -8/2
divide -8 by2 to get -4
add -4 and 3 to get -1
y=-1
Answer:
Domain t ∈ [0, 8.4615]
Range d ∈ [0, 11]
t = 3.538 h (d = 6.4 in)
d(6.4 h) = 2.68 in
t = 8.4615 h (d = 0 in)
Step-by-step explanation:
Given
v = - 1.3 in/h
d₀ = 11 in
We use the formula
v = d/t ⇒ d(t) = v*t + d₀ = - 1.3*t + 11
Domain t ∈ [0, 8.4615]
At the beginning t = 0 ⇒ d(0) = v*0 + d₀ = 0 + 11 = 11
At the end d(t) = 0 ⇒ 0 = - 1.3*t + 11 ⇒ t = 8.4615
Range d ∈ [0, 11]
If d(t) = 6.4 in
t = ?
6.4 = - 1.3*t + 11 ⇒ t = 3.538 h
If t = 6.4 h
d = ?
d(6.4) = - 1.3*(6.4) + 11 = 2.68 in
If d = 0
t = ?
0 = - 1.3*t + 11 ⇒ t = 8.4615 h
