Answer:

2.3 hours

Step-by-step explanation:

From 3:12 pm to 4:12 pm, one hour passes.

From 4:12 pm to 5:12 pm, another hour passes.

From 5:12 pm to 5:30 pm, there are 18 minutes that pass.

Therefore, the total time elapsed is 2 hours and 18 minutes out of 60 minutes in an hour.

To convert this to a fraction, we can write:

2 hours + 18 minutes = 2 + 18/60 hours = 2.3 hours

So, 2.3/1 hour passes from 3:12 pm to 5:30 pm.

Answer:

Step-by-step explanation:

You have a chemical that decayed from 39.2 barrels after 4 days to 21.5 barrels after 7 days, and you want to know the initial amount, the rate of change after 4 days, and the number of days until the amount is 2 barrels.

Given two value and times (t₁, v₁) and (t₂, v₂), you can write the exponential function that models this change as ...

  \(v(t)=v_1\left(\dfrac{v_2}{v_1}\right)^{\dfrac{t-t_1}{t_2-t_1}}\\\\\boxed{v(t)=39.2\left(\dfrac{215}{392}\right)^{\dfrac{t-4}{3}}}\)

The initial amount is v(0):

  v(0) = 39.2(215/392)^(-4/3) ≈ 87.3

About 87.3 barrels were initially dumped in the swamp.

The rate of change after 4 days is the value of the derivative of the function at that time.

  v'(t) = 39.2(1/3)(215/392)^((t-4)/3))·ln(215/392)

  v'(4) = 39.2(1/3)·ln(215/392) ≈ -7.8 . . . barrels per day

The Trioxin was decreasing at a rate of 7.8 barrels per day.

We can solve for t:

  v(t) = 2 = 39.2(215/392)^((t-4)/3)

  2/39.2 = (215/392)^((t-4)/3) . . . . . . . . divide by 39.2

  ln(20/392) = (t -4)/3·ln(215/392) . . . . . take logs

  t -4 = 3·ln(5/98)/ln(215/392) . . . . . . . . . . divide by the coefficient of t-4

  t = 4 +3·ln(5/98)/ln(215/392) ≈ 18.9

It will take about 18.9 days for the amount to drop to 2 barrels.

__

Additional comment

Often, an exponential model is of the form ...

  v(t) = v₀·e^(kt)

In this form, the model is ...

  v(t) = 87.314·e^(-0.20021t) ≈ 87.3e^(-0.2t)

The required relationship shown between x and y in table 1 is a function.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variables.

Here,

The relationship shown between x and y in table 1 is a function.
To determine if the relationship between x and y is a function, we need to check if each x-value corresponds to exactly one y-value.

We can see that for each x-value, there is only one corresponding y-value:

When x = -6, y = 2

When x = -4, y = 4/3

When x = -2, y = 2/3

When x = 0, y = 0

When x = 2, y = 2/3

Each value of x corresponds to only one value of y, so the relationship is a function.

Therefore, the relationship shown between x and y in table 1 is a function.

To find out how many more yards of red fabric Reuben used, we need to subtract the amount of yellow fabric from the amount of red fabric. Since the two fractions have different denominators, we need to find a common denominator before subtracting them. The least common multiple of 8 and 4 is 8, so we can rewrite both fractions with a denominator of 8:

7/8 - 1/4 = 7/8 - (1/4) * (2/2) = 7/8 - 2/8 = (7 - 2)/8 = 5/8

So, Reuben used 5/8 yards more red fabric than yellow fabric.

We know the value of h and k.

\(y = a(x - 4)^{2} - 1\)

The graph passes through (2,3). Therefore, substitute x = 2 and y = 3.

\(3 = a {(2 - 4)}^{2} - 1\)

Solve for a.

\(3 = a {( - 2)}^{2} - 1 \\ 3 = 4a - 1 \\ 3 + 1 = 4a \\ 4 = 4a \\ \frac{4}{4} = a \\ 1 = a\)

Therefore, a = 1. Rewrite the equation.

\(y = 1 {( x - 4)}^{2} - 1 \\ y = {(x - 4)}^{2} -1\)

=============================================

Explanation for problem 23.

Check out figure 1 shown below.

I have marked the given diagram with light blue and light pink to show which angles are congruent.

Because lines UN and TC are parallel, we know the following alternate interior pairs are congruent.

Therefore, we can establish one link of paired congruent angles of the triangles LNU and TCH. However, we cannot determine any other angle pairings. Why not? Because we don't know if segment UL is parallel to segment TH. If they were parallel, then we could establish something like angle LUN = angle CHT as one alternate interior pairing.

But again, we don't know if UL is parallel to TH. The arrow markers aren't shown for these segments.

Therefore, we simply don't have enough information to determine if the triangles are similar or congruent.

----------------------------------------

Explanation for problem 25.

Luckily this problem will provide sufficient info to prove the triangles KSR and ISR are congruent.

We start with the given info that KR = SI due to the identical tickmarks. This represents one node in the flowchart (see figure 2).

Another node is angle RKS = angle RIS because both are right angles, aka 90 degree angles.

A third node is SR = SR because of the reflexive property.

Those three nodes then feed into the final conclusion node that triangle KSR = triangle ISR. The reasoning is "HL theorem" where HL = hypotenuse leg. This theorem works for right triangles only.

Take note how I structured the proof so that it flows from top to bottom. The three nodes side by side are related so they share the same row.

There are many other ways to make the flowchart, so don't feel obligated to use this format. Use whatever works best for you.

The rate at which the volume of the cylinder is changing is 600 mm^3/min, and the rate at which the surface area is changing is 240π mm^2/min.

To find the rate at which the volume and surface area of the cylinder are changing, we can use the given formulas for volume and surface area and differentiate them with respect to time. Let's calculate the rates at the moment when the radius of the base is 10 mm.

Given:

Radius rate of change: dr/dt = 3 mm/min

Height: h = 20 mm

Radius: r = 10 mm

Volume of the cylinder (V) = \(r^2h\)

Differentiating with respect to time (t), we have:

dV/dt = 2rh(dr/dt) + \(r^2\)(dh/dt)

Since the height of the cylinder is constant, dh/dt = 0.

Substituting the given values:

dV/dt = 2(10)(20)(3) + (10^2)(0)

dV/dt = 600 + 0

dV/dt = 600 mm^3/min

Therefore, the rate at which the volume of the cylinder is changing at the given moment is 600 mm^3/min.

Surface area of the cylinder (SA) = 2πrh + 2π\(r^2\)

Differentiating with respect to time (t), we have:

dSA/dt = 2πr(dh/dt) + 2πh(dr/dt) + 4πr(dr/dt)

Again, since the height of the cylinder is constant, dh/dt = 0.

Substituting the given values:

dSA/dt = 2π(10)(0) + 2π(20)(3) + 4π(10)(3)

dSA/dt = 0 + 120π + 120π

dSA/dt = 240π mm^2/min

Therefore, the rate at which the surface area of the cylinder is changing at the given moment is 240π mm^2/min.

  $142.32, profit on sale of the policy

Step-by-step explanation:

You want to know the expected value of a $280,000 life insurance policy sold for $270, if the probability the insured will live for the year is 0.999544.

The insurance company expects to have to pay the $280,000 death benefit for 0.000456 of the policies issued. That means their expected payout on any one policy is ...

  0.000456 × $280,000 = $127.68

The company gets a premium of $270 for the policy, so the expected value of the policy to the company is ...

  $270 -127.68 = $142.32

The expected value of the policy to the company is $142.32.

This represents its profit from sale of the policy.

Of course, the company has expenses related to the policy, perhaps including a commission to the agent selling it, and expenses related to handling claims.
