A mountain in jackson county is eroding and losing elevation at a rate of 5% every millennium. If the current elevation is 1,300 meters, how tall will the mountain be in 8 millennia?.
So the mountain will be approximately 798.02 meters tall after 8 millennia.
The mountain loses 5% of its elevation every millennium, which is the same as losing 0.05 * its current elevation. Therefore, after 1 millennium, the mountain's elevation will be 1 - 0.05 = 0.95 times its current elevation. After 2 millennia, it will be 0.95 * 0.95 = 0.9025 times its current elevation, and so on.
After 8 millennia, the mountain's elevation will be 0.95^8 times its current elevation. We can calculate this as follows:
Elevation after 8 millennia = 1,300 meters * 0.95^8
= 1,300 meters * 0.6134
= approximately 798.02 meters
So the mountain will be approximately 798.02 meters tall after 8 millennia.

Explain the Triangle Inequality Theorem as it relates to angles.
Answer:
The Triangle Inequality Theorem states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side. In other words, the length of one side of a triangle must always be shorter than the sum of the lengths of the other two sides. This theorem is often used in geometry to determine whether or not a given set of lines can form a triangle.
When it comes to angles, the Triangle Inequality Theorem can be used to determine whether or not a triangle can be formed given the measures of its angles. For example, if the measures of two angles in a triangle are 45 degrees and 60 degrees, the measure of the third angle must be less than 180 degrees - 45 degrees - 60 degrees, or 75 degrees. If the measure of the third angle is greater than 75 degrees, it is not possible for the three angles to form a triangle.
Overall, the Triangle Inequality Theorem is a useful tool for understanding the relationships between the sides and angles of a triangle, and for determining whether or not a given set of lines or angles can form a triangle.

Answer:
Step-by-step explanation: Perform any simplification of like terms if possible
7x=3x+16
Collect x terms on one side. Can use the left side for x terms. That means 3x must dissapear. To do this we need to take 3x from both sides.
7x-3x=3x-3x+16
4x=16
To solve for x we need to divide by 4 on both sides

A curve has equation y = x³ + ax + b.
The stationary points of the curve have coordinates (2, k) and (-2, 10-k).
Work out the value of a, the value of b and the value of k.
The value of 'a' is equal to -12, the value of 'b' is equal to 5 and the value of 'k' is equal to -11.
The stationary points of a curve are those points at which the first derivative of the function f(x) becomes zero. At the stationary points, the nature of the function is neither increasing nor decreasing.
→ The stationary points of a curve can either be a local minima or a local maxima of the function.
→ If we plot the graph of the curve, then stationary points can be said to be those points at which the tangent to the curve becomes horizontal which means the tangent becomes parallel to the x-axis.
→ Therefore for a point (a,b) to be the stationary point of a function f(x): f'(a) must be equal to zero.
→ For the given question:
f(x) = y = x³ + ax + b
f'(x) = 3x² + a
(2, k) is a stationary point:
f'(2) = 0
f'(2) = 3(2)² + a = 0
a = -12
The value of 'a' comes out to be equal to -12.
→ Hence the equation of the curve is: y = x³ - 12x + b
→ The stationary points (2, k) and (-2, 10-k) must be lying on the curve, hence they must satisfy the equation of the curve:
→ Putting (2, k) in the equation of the curve:
k = (2)³ - 12(2) + b
(k - b) = -16 - Equation (i)
→ Putting (-2, 10 - k) in the equation of the curve:
(10 - k) = (-2)³ -12(-2) + b
(10 - k) = -8 + 24 + b
b = -6 - k - Equation (ii)
→ Putting the value of 'b' from the equation (ii) in equation (i):
k - (-6 - k) = -16
k + 6 + k = -16
2k = -22
k = -11
∴ The value of 'k' comes out to be equal to -11.
→ Putting the value of 'k' in equation (i):
k - b = -16
-11 - b = -16
b = 5
∴ The value of 'b' comes out to be equal to 5.
Therefore, the value of 'a' is equal to -12, the value of 'b' is equal to 5 and the value of 'k' is equal to -11.

V (ft/s) 0 6.2 10.8 14.9 18.1 19.4 20.2
She can only move a certain distance in three seconds, with a lower distance of 33.45 feet and a upper distance of 43.45 feet.
The first three seconds of a race saw a runner's speed rapidly grow.
The time is therefore 3 seconds.
The table provides her speed at half-second intervals.
We are aware,
Speed = Distance / Time
Similarly
Distance = Speed × Time
t equals 0.5 seconds
Then, the lower distance traveled overall is equal to 0.5(0 + 6.7 + 9.2 + 14.1 + 17.5 + 19.4).
Terms are multiplied and added.
= 0.5 × 66.9
= 33.45 feet
The upper distance traveled is equal to 0.5 (6.7 + 9.2 + 14.1 + 17.5 + 19.4 + 20)
= 0.5 × 86.9
= 43.45 feet
As a result, Her lower distance in three seconds is therefore 33.45 feet, and her upper distance in three seconds is 43.45 feet.

p varies directly with T and p = 400. When T = 500. Find the value of p when T = 600
Answer:
Step-by-step explanation:
When the temperature T is 500, the pressure p is 400. If we let "k" represent the constant of proportionality that relates p and T, then we can write the relationship between p and T as:
p = k * T
Substituting the known values of p and T into this equation, we get:
400 = k * 500
Solving for the constant of proportionality k, we find that:
k = 400/500 = 0.8
Now that we know the value of the constant of proportionality k, we can use it to find the value of p when T = 600. Substituting this value of T into the equation above and solving for p, we get:
p = 0.8 * 600 = 480
Therefore, when T = 600, the pressure p is 480.
there are six balls in a box if we select three balls what is the probability of having one white ball
The probability of having one white ball is 1/20 or approximately 0.05.
To find the probability of selecting one white ball out of three balls, you need to know the number of white balls in the box and the total number of balls in the box. You also need to know whether the balls are being selected randomly or not.
Assuming that there is only one white ball in the box and the rest are some other color, and that the balls are being selected randomly.
The probability of selecting one white ball out of three would be:
Probability = (number of ways to select one white ball out of three) / (total number of ways to select three balls)
Since there is only one white ball, there is only one way to select one white ball out of three. The total number of ways to select three balls out of six is 6 choose 3, which is equal to 20.
Therefore, the probability of selecting one white ball out of three would be
Probability = (number of ways to select one white ball out of three) / (total number of ways to select three balls)
Probability = 1/20

How do you write a preimage?
Answer: The image T(V) is defined as the set {k | k=T(v) for some v in V}. So x=T(y) where y is an element of T^-1(S). The preimage of S is the set {m | T(m) is in S}. Thus T(y) is in S, so since x=T(y), we have that x is in S.
Given a function f:A→B, and D⊆B, the preimage D of under f is defined as f−1(D)={x∈A∣f(x)∈D}. Hence, f−1(D) is the set of elements in the domain whose images are in C. The symbol f−1(D) is also pronounced as “f inverse of D.”

What is special about rigid motion transformations?
A rigid body motion, also known as a rigid transformation, happens when a point or object travels while maintaining its size and shape.
What are the characteristics of a rigid motion transformations?While the image's size and shape are unaffected by rigid body motion, its location and orientation are. The three fundamental movements of a rigid body are translation, reflection, and rotation. Prior to movement, archetypes depict points or forms.
A rigid body motion, also known as a rigid transformation, happens when a point or object travels while maintaining its size and shape. Stretching and other non-rigid motions, which alter an object's size, are not comparable to this.
Area of triangle = 1/2 X b X h
b= 10
h=5
A = 1/2 X 10X 5
A = 25 unit sq.
