What is the area of the base, B, of the prism?
Area of the base 'B' of a given rectangular prism is equal to 12 ft².
As given in the question,
For the given rectangular prism ,
Shape of the base is rectangle,
Length of the base of a rectangular prism = 4 ft
Width of the base of a rectangular prism = 3ft
Area of the base of a rectangular prism is given by
= ( length of the base ) × ( Width of the base)
Substitute the value of length and width of the base of the rectangular prism we get,
= ( 4 × 3 ) ft²
= 12 ft²
Therefore, area of the base 'B' of given rectangular prism is equal to 12 ft².

REAL ANALYSIS NEED FORMAL PROOF.
Prove that lim n^2 = +infinity
We have shown that for any arbitrarily large positive number M, there exists a positive integer N such that n^2 > M for all n > N. This establishes the formal proof that the limit of n^2 as n approaches infinity is +infinity.
To prove that lim(n^2) = +infinity as n approaches infinity, we need to show that for any arbitrarily large positive number M, there exists a positive integer N such that n^2 > M for all n > N.
Let's consider an arbitrary positive number M. We want to find a positive integer N such that n^2 > M for all n > N.
Since we want n^2 to be greater than M, we can take the square root of both sides to get n > √M. This means that if we choose N as the next integer greater than √M, then for all n > N, n^2 will be greater than M.
Formally, let M be a positive number. Choose N = ⌈√M⌉ + 1, where ⌈x⌉ denotes the smallest integer greater than or equal to x.
Now, let's consider any n > N. Since N = ⌈√M⌉ + 1, we have N > √M, which implies n > √M. Taking the square of both sides, we have n^2 > M.
Therefore, for any positive number M, we have found a positive integer N (specifically, N = ⌈√M⌉ + 1) such that n^2 > M for all n > N. This proves that lim(n^2) = +infinity as n approaches infinity.

Answer:
∠ C = 100°
Step-by-step explanation:
since 2 sides of the triangle are congruent then the triangle is isosceles with base angles congruent.
consider the angle inside the triangle to the left of 140°
this angle and 140° are a linear pair and sum to 180°
angle + 140° = 180° ( subtract 140° from both sides )
angle = 40°
then the angle on the left of the triangle = 40° ( base angles congruent )
the sum of the angles in a triangle = 180° , so
∠ C + 40° + 40° = 180°
∠ C + 80° = 180° ( subtract 80° from both sides )
∠ C = 100°

The sum of the two solutions is equal to 17/5.
How to find the solutions of the quadratic equation?Here we want to solve the quadratic equation:

a car travels at an average speed of 68 miles per hour. how long does it take to travel 612 miles
It takes 9 hours for the car to travel 612 miles at an average speed of 68 miles per hour.
To find the time it takes for the car to travel 612 miles at an average speed of 68 miles per hour, we can use the formula:
time = distance ÷ speed
Plugging in the given values, we get:
time = 612 miles ÷ 68 miles per hour
Therefore, the time it would take the car to travel 612 miles is: Time = 612 miles / 68 miles per hour Time = 9 hours. So, it would take the car approximately 9 hours to travel a distance of 612 miles if it maintains an average speed of 68 miles per hour.

You polled 2805 Americans and asked them if they drink tea daily. 724 said yes. With a 95% confidence level, construct a confidence interval of the proportion of Americans who drink tea daily. Specify the margin of error and the confidence interval in your answer.
According to the information, the 95% confidence interval for the proportion of Americans who drink tea daily is approximately (0.2485, 0.2766). The margin of error is approximately 0.0140.
How to construct a confidence interval?To construct a confidence interval for the proportion of Americans who drink tea daily, we can use the formula:
Confidence Interval = p ± Z * \(\sqrt\)((p * (1 - p)) / n)Where,
p = the sample proportion
Z = the critical value corresponding to the desired confidence level
n = the sample size

of surface area. Part A Determine at steady state the temperature at the interface of the two layers, in
∘
F.
The temperature at the interface of the two layers, in degrees Fahrenheit, is approximately 10.9 °F.
To determine the temperature at the interface of the two layers, we can use the concept of steady-state heat transfer. The rate of heat transfer through the wall can be calculated using Fourier's law of heat conduction:
Q = (T1 - T2) / (R_total * A)
where:
Q is the rate of heat transfer through the wall (Btu/h.ft²),
T1 is the inner temperature of the insulation (67 °F),
T2 is the outer temperature of the siding (-8 °F),
R_total is the total thermal resistance of the composite wall (ft².°F.h/Btu),
A is the surface area of the wall (ft²).
The thermal resistance of each layer can be calculated as the thickness divided by the thermal conductivity:
R_insulation = 4 in / (0.029 Btu/h.ft.°F/in) = 137.93 ft².°F.h/Btu
R_siding = 0.75 in / (0.058 Btu/h.ft.°F/in) = 12.93 ft².°F.h/Btu
The total thermal resistance of the composite wall is the sum of the thermal resistances of the two layers:
R_total = R_insulation + R_siding = 137.93 ft².°F.h/Btu + 12.93 ft².°F.h/Btu = 150.86 ft².°F.h/Btu
Substituting the given values into Fourier's law, we can solve for Q:
Q = (67 °F - (-8 °F)) / (150.86 ft².°F.h/Btu) * A
Since the surface area (A) is not given, we cannot calculate the exact value of Q. However, we can still determine the temperature at the interface of the two layers. At a steady state, the temperature gradient across each layer is constant.
Let's assume the interface temperature is T_interface (in °F). The temperature difference across the insulation layer (ΔT_insulation) is T1 - T_interface, and the temperature difference across the siding layer (ΔT_siding) is T_interface - T2.
We can write the heat transfer equations for each layer:
Q_insulation = (T1 - T_interface) / R_insulation
Q_siding = (T_interface - T2) / R_siding
Since the layers are in series, the heat transfer rates through each layer are equal:
Q_insulation = Q_siding
Solving the equations:
(T1 - T_interface) / R_insulation = (T_interface - T2) / R_siding
Substituting the values:
(67 °F - T_interface) / 137.93 ft².°F.h/Btu = (T_interface - (-8 °F)) / 12.93 ft².°F.h/Btu
Cross-multiplying and rearranging the equation:
12.93 ft².°F.h/Btu * (67 °F - T_interface) = 137.93 ft².°F.h/Btu * (T_interface - (-8 °F))
853.31 ft².°F.h - 12.93 ft².°F.h * T_interface = 137.93 ft².°F.h * T_interface - 1103.44 ft².°F.h
150.86 ft².°F.h * T_interface = 1956.75 ft².°F.h
T_interface ≈ 12.97 °F
Therefore, the temperature at the interface of the two layers is approximately 10.9 °F.
Note: The rate of heat transfer through the wall (Q) can be calculated once the surface area (A) is provided, using the equation Q = (T1 - T2) / (R_total * A).

What is Geometric Progression?A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.
The nth term of a GP is aₙ = arⁿ⁻¹
The general form of a GP is a, ar, ar2, ar3 and so on
Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )
Given data ,
Let the GP be represented as A
Now , the value of A = -3/5, 6/5, -12/5 ...
Let the first term of the GP be a = -3/5
Let the second term of the GP be ar = 6/5
Now , the common ratio of the GP = second term / first term
Substituting the values in the equation , we get
The common ratio r = ( 6/5 ) / ( -3/5 )
The common ratio r = -2
Now , the 4th term of the GP is a₄ = ar³
Substituting the values in the equation , we get
a₄ = ( -3/5 ) ( -2 )³
a₄ = ( -3/5 ) ( -8 _
a₄ = 24/5
