In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size. [Therefore proven] BD=BC.

A parallelogram is a straightforward (non-self-intersecting) quadrilateral in Euclidean geometry that has two sets of parallel sides.

In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.

There are

As well as AB=AC, BC 2 = AC / CD.

B = C and BC = BC = AC

The notation AC BC equals BC CD, and B = C.

CA BC equals CB DC and B = C.

Thus, based on the similarity criterion of SAS, we have

△BCA∼△DCB

DC/ BC = CB /CA = DB/ BA

CB /CA = DB/ BA

CA/ BA = CB /DB

The given k-value of 0.1459, we can calculate the amount of the sample left after any given amount of time.

Amount is a numerical quantity that is used to measure the size or magnitude of something. It is typically expressed in terms of a unit of measure such as a dollar, pound, or other currency.

The given k-value of 0.1459 corresponds to the rate of decay of the 9 gram sample of the substance over time. The equation for determining the amount of the sample left after a certain amount of time (t) is: N = -kt, where N is the amount of the sample left after the given amount of time, k is a positive constant that depends on the substance itself and on the units used to measure time, and t is the amount of time in days.

N = N0 e^(-kt)

for half life N/N0 = 1/2 and k = 0.1459

1/2 = e^(-0.1459t)

=> -0.1459 t = ln(0.5)

t = - ln(0.5) /0.1459

= 4.8 days       

Therefore, with the given k-value of 0.1459, we can calculate the amount of the sample left after any given amount of time.

The perception of the Olympic logo as interlocking circles is due to the human brain's tendency to simplify and organize visual information.

This is known as "gestalt psychology," where our brain perceives objects as a whole rather than individual elements. The circles provide a clear and recognizable shape that is easy for our brain to process, whereas a series of complex shapes might be harder to understand and remember.

The circles are a consistent and repeated shape in the design, further emphasizing their perception as the main element. In conclusion, it's the brain's innate pattern recognition ability and our cultural familiarity with the design that lead us to see the Olympic logo as interlocking circles.

The speed of the person located at earth's equator traveling due to rotation is, 1670 km/hr.

The person at equator traveling due to it's rotation will cover one complete round of earth in 24 hours. Hence the distance travelled is the circumference of the earth.

The radius of the earth is, 6 378.1 kilometers.

The circumference can be calculated as, 2×π×R

Using R = 6 378.1 kilometers,

Circumference = 2×π×6 378.1 kilometers

Circumference = 40090.91 kilometers.

The distance traveled = 40090.91 kilometers.

Time taken is 24 hrs.

Hence speed = distance/time

Speed = 40090.91/24

Speed = 1670 km/hr

If the builder does not build houses with three-car or more garages, then the probability that the buyer will select no garage home is 0.1.

Probability is a measure of likelihood that a certain event occurs. The probability of an event A is defined as:

P(A) = n(A)/n(S)

Where:

n(A) = number of ways the event A can occur

n(S) = number of all possible outcomes.

Suppose there are 3 possible outcomes, A, B, C, then:

P(S) = P(A) + P(B) + P(C) = 1

In the problem, let's define the events:

A = buyer will select a one-car garage

B = buyer will select a two-car garage

C = buyer will select no car garage

We have:

P(A) = 0.2

P(B) = 0.7

Hence,

P(A) + P(B) + P(C) = 1

0.2 + 0.7 + P(C) = 1

Quadrilateral CDEF is inscribed in circle A. Which statements complete the proof to show that ∠CFE and ∠CDE are supplementary?

Quadrilateral CDEF is inscribed in circle A, so mARC CDE + mARC CFE= 360°. ∠CFE and ∠CDE are inscribed angles, which means that their measures are _________________. So, _________________. Using the substitution property of equality, 2 ⋅ m∠CFE + 2 ⋅ m∠CDE = 360°. Using the division property of equality, divide both sides of the equation by 2, resulting in m∠CFE + m∠CDE = 180°. Therefore, ∠CFE and ∠CDE are supplementary.

The expected population in an additional 4 years is 15,125.

The expected population can be found by using the formula for uninhibited exponential growth.

Uninhibited exponential growth is modeled by the formula

P(t) = P₀ * e^(rt)

where P₀ is the initial population, e is the base of natural logarithms (approximately equal to 2.718), r is the growth rate, and t is the time elapsed.

We can first find the growth rate by using the formula

r = (ln(P/P₀)) / t

where P is the final population and t is the time elapsed. In this case, P₀ = 8000, P = 12000, t = 7 years, so we have:

r = (ln(12000/8000)) / 7

= 0.4055 / 7

= 0.0579

Next, we can use this growth rate to predict the population in an additional 4 years. Let t' = t + 4, so we have:

P(t') = P₀ * e^(r * t')

= 8000 * e^(0.0579 * (7 + 4))

Using a calculator, we can find that P(t') ≈ 15,125.
