85% of P78 is what amount?
Answer:
We can find the answer by multiplying the percentage (85%) by the value (P78):
85% of P78 = 0.85 * P78
So, the amount that represents 85% of P78 is 0.85 times P78.
If we know the value of P78, we can substitute it into the formula to find the answer. For example, if P78 is 100, then:
85% of P78 = 0.85 * 100 = 85
Therefore, 85% of P78 is 85, if P78 is 100. If the value of P78 is different, the answer will be different.

\((x,y) \to \left(\frac{5}{2}x,\frac{5}{2}y\right)\)
=========================================================
Explanation:
When dilating with respect to the origin, any point of the form (x,y) moves to (kx, ky) for some real number k. The k is the scale factor.
Point C is at (-2,2). It moves to C ' (-5,5)
The jump from x = -2 to x = -5 is "times 5/2" since kx = (5/2)*(-2) = -5
The same scale factor is used when going from y = 2 to y = 5.
Both x and y coordinates are multiplied by 5/2 to move from (-2,2) to (-5,5)
Therefore, the dilation rule we use is \((x,y) \to \left(\frac{5}{2}x,\frac{5}{2}y\right)\)
-----------
We could have these steps to confirm
\((x,y) \to \left(\frac{5}{2}x,\frac{5}{2}y\right)\\\\(-2,2) \to \left(\frac{5}{2}*(-2),\frac{5}{2}(2)\right)\\\\(-2,2) \to (-5,5)\\\\\)
In your reservoir, you have a production well which flows for 48 hours at 200 STB/day, and then shut-in for 24 hours. The following additional data are given : Pi = 3100 psi Ct = 15x10^-6 psi^-1 Bo = 1.3 bbl/STB ϕ = 15% μ=1.2 cp K = 45 md and h = 60 ft
a-) Calculate the pressure in this production well at 12 hours of shut in
b-) Explain how can you use superposition in time to analyze a pressure build-up test.
a) To calculate the pressure at 12 hours of shut-in:
substitute the given values into the pressure buildup equation and solve for P(t=12).
b) Superposition in time is used in pressure buildup analysis by adding or summing the responses of multiple transient tests to analyze and interpret reservoir behavior and properties.
We have,
a) To calculate the pressure in the production well at 12 hours of a shut-in, we can use the equation for pressure transient analysis during shut-in periods, known as the pressure buildup equation:
P(t) = Pi + (Q / (4πKh)) * log((0.14ϕμCt(t + Δt)) / (Bo(ΔP + Δt)))
Where:
P(t) = Pressure at time t
Pi = Initial reservoir pressure
Q = Flow rate
K = Permeability
h = Reservoir thickness
ϕ = Porosity
μ = Viscosity
Ct = Total compressibility
t = Shut-in time (12 hours)
Δt = Time since the start of the flow period
Bo = Oil formation volume factor
ΔP = Pressure drop during the flow period
Given:
Pi = 3100 psi
Q = 200 STB/day
K = 45 md
h = 60 ft
ϕ = 15%
μ = 1.2 cp
Ct = 15x10^-6 psi^-1
Bo = 1.3 bbl/STB
t = 12 hours
Δt = 48 hours
ΔP = Pi - P(t=Δt) = Pi - (Q / (4πKh)) * log((0.14ϕμCt(Δt + Δt)) / (Bo(ΔP + Δt)))
Substituting the given values into the equation:
ΔP = 3100 - (200 / (4π * 45 * 60)) * log((0.14 * 0.15 * 1.2 * 15x\(10^{-6}\) * (48 + 48)) / (1.3 * (3100 - (200 / (4π * 45 * 60)) * log((0.14 * 0.15 * 1.2 * 15 x \(10^{-6}\) * (48 + 48)) / (1.3 * (0 + 48))))))
After evaluating the equation, we can find the pressure in the production well at 12 hours of shut-in.
b) Superposition in time is a principle used in pressure transient analysis to analyze and interpret pressure build-up tests.
It involves adding or superimposing the responses of multiple transient tests to simulate the pressure behavior of a reservoir.
The principle of superposition states that the response of a reservoir to a series of pressure changes is the sum of the individual responses to each change.
Superposition allows us to combine the information obtained from multiple tests and obtain a more comprehensive understanding of the reservoir's behavior and properties.
It is a powerful technique used in reservoir engineering to optimize production strategies and make informed decisions regarding reservoir management.
Thus,
a) To calculate the pressure at 12 hours of shut-in:
substitute the given values into the pressure buildup equation and solve for P(t=12).
b) Superposition in time is used in pressure buildup analysis by adding or summing the responses of multiple transient tests to analyze and interpret reservoir behavior and properties.

Answer:
Yes, store's profit is proportional to number of customers

The cross sections of the cone shown can be circle, oval, parabola and triangle.
What is Cross Section?Cross section of a figure or shape can be defined as a plane intersecting with the figure. The resulting shape formed in the intersection part is termed as cross section.
Given shape is a cone.
When a cone is intersected vertically, then the cross section formed is triangle.
When the cone is intersected through the straight horizontal line, we get the cross section as circle.
We will get an oval shape when the cone is intersected with the plane with a given slant by not touching the base.
A parabola shape is formed when a slant plane intersects by touching the base
Hence the cross sections of the given cone are circle, oval, parabola and triangle.

solve 5(2^x+4)=15 round to the nearest thousandth

Begin by dividing by 5
2x + 4 = 3
Is this written as 2^(x + 4) = 3? I think it is.
Take the log of both sides
log 2^(x + 4) = log(3)
(x + 4) * log(2) = log 3
log 2 = 0.30103
log 3 = 0.47712
(x + 4) = log2 / log3
x + 4 = 0.63093 Add 4 to both sides
x = -3.369 Rounded to the nearest thousandth
====================
If you mean the question exactly as it is written (the 4 is not part of the power)

2^x + 4 = 3
2^x = 3 - 4
2^x = - 1

how frequently rna polymerase binds to this sequence
The amount of RNA transcribed from promoter gene, which can consequently influence the amount of protein made from this gene. So the option c is correct.
A gene's DNA sequence is duplicated during transcription in order to create an RNA molecule.
The primary transcribed enzyme is called RNA polymerase.
RNA polymerase connects to a promoter sequence close to the start of a gene to start transcription (directly or through helper proteins).
A new, complementary RNA molecule is created by RNA polymerase using a template from one of the DNA strands (the template strand).
Termination is the procedure that brings transcription to a conclusion. The RNA sequences that indicate that the transcript is done are what determine when a process is terminated.

A researcher believes the mean for a certain normally distributed population is 102. The standard deviation is known to be 15. What's the P-value of drawing a random sample of 50 and getting a mean of 100 or less
The P-value of drawing a random sample of 50 and getting a mean of 100 or less is approximately 0.1726 (17.26%).
The Z-score formula is given by,
Z = (X - μ)/(σ/√(n))
X = Sample mean (100)
μ = Population mean (102)
σ = Standard deviation (15)
n = Sample size (50)
Let's calculate the Z-score,
Z = (100 - 102)/(15/√(50))
Z = -2 / (15 / 7.071)
Z = -0.9428
To find the P-value, we need to determine the probability of obtaining a Z-score less than or equal to -0.9428 from the standard normal distribution. We can use a Z-table or a statistical calculator to find this probability.
Looking up the Z-score -0.9428 in a standard normal distribution table, we find that the corresponding cumulative probability is approximately 0.1726. Therefore, the P-value of drawing a random sample of 50 and getting a mean of 100 or less is approximately 0.1726, or 17.26%.

Find the indicated one-sided limits, if they exist. (if an answer does not exist, enter dne.)
The limit doesn't exist.
What is a limit?
The value that a function (or sequence) approaches when the input (or index) gets closer to a particular value is known as a limit. Calculus and mathematical analysis are impossible without limits, which are also required to determine continuity, derivatives, and integrals.
In addition to being closely related to limit and direct limit in category theory, the idea of a limit of a sequence is further generalized to include the concept of a limit of a topological net.
A function's limit is typically expressed in formulas as
\(\lim_{x \to c } F(x) = L\)
It is typically used to assign values to specific functions at locations where none are defined while maintaining consistency with existing values.
\(F(x) = -x+8 ,x\leq 0\)
\(F(x) = 4x+9 , if x > 0\)
\(\lim_{x \to 0^{+} } F(x) = \lim_{n \to 0^{+} } (4x+9) = 9\)
\(\lim_{x \to 0^{-} } F(x) = \lim_{x \to 0^{-} } (-x+8) =8\)
\(\lim_{x \to 0^{+} } F(x) \neq \lim_{x \to 0^{-} } F(x)\)
So limit doesn't exist
For limit to exist
\(\lim_{x \to 0^{+} } F(x) = \lim_{x \to 0^{-} } F(x) = \lim_{x \to 0} f(x)\)
