Answer:

[4, positive infinity)

Step-by-step explanation:

since there is a closed circle on 4, we include 4 in the continuous interval, and we assume that the arrow represents continuity after the graph ends, so the interval of continuity is from 4 to positive infinity.

The midpoint of AB is M(-3, 0). If the coordinates of A are (1,-4), what are the coordinates of B?

zimovet [89]

Using the given information, the coordinates of B are (-7, 4)

<h3>Midpoint of a Line </h3>

From the question, we are to determine the coordinates of B.

Given a line with endpoints (x₁, y₁) and (x₂, y₂), then the midpoint of the line is

((x₁+x₂)/2, (y₁+y₂)/2)

From the given information,

The midpoint of AB is M(-3, 0)

and

The coordinates of A are (1,-4)

Let the coordinates of B be (x₁, y₁)

Then,

-3 = (1 + x₁)/2

-6 = 1 + x₁

x₁ = -6 -1

x₁ = -7

Also,

0 = (-4 + y₁)/2

0 = -4 + y₁

y₁ = 0 + 4

y₁ = 4

Hence, the coordinates of B are (-7, 4)

A 3650-year-old wooden chest is found by archaeologists. What percentage of the original Superscript 14 Baseline Upper C would

AfilCa [17]

Answer:

64.5%

Step-by-step explanation:

Initial amount N° = ?

Remaining amount after decay = N = ?

k = decay constant = 0.00012 $yr^{-1}$

t = time = 3650 year

fraction remaining will be N/N°

From the decay equation, N = N° $e^{-kt}$

N/N° = $e^{-kt}$

N/N° = $e^{-0.00012 x 3650 }$

N/N° = $e^{-0.438}$

N/N° = 0.645 = 64.5%
