HELP ASAP PLZ.​

Consider the rectangle: 4V20 + 2V24 3V8 Select all expressions that are equivalent to the perimeter of

Answers

The perimeter of a rectangle is the sum of visible lengths of the rectangle. The equivalent expressions are:

\(P = 2(4\sqrt{20} + 2\sqrt{24} + 3\sqrt 8)\)

\(P = 2(3\sqrt 8) +2(4\sqrt{20} + 2\sqrt{24})\)

\(P = 12\sqrt{2} + 16\sqrt{5} + 4\sqrt{6}\)

Given that:

\(L = 4\sqrt{20} + 2\sqrt{24}\) --- Length

\(W = 3\sqrt 8\) --- Width

The perimeter (P) of the rectangle is:

\(P = 2 \times (L + W)\)

So, we have:

\(P = 2 \times (4\sqrt{20} + 2\sqrt{24} + 3\sqrt 8)\)

\(P = 2(4\sqrt{20} + 2\sqrt{24} + 3\sqrt 8)\)

Rewrite as:

\(P = 2( 3\sqrt 8+4\sqrt{20} + 2\sqrt{24})\)

Expand

\(P = 2(3\sqrt 8) +2(4\sqrt{20} + 2\sqrt{24})\)

Further expand

\(P = 6\sqrt 8 +8\sqrt{20} + 2\sqrt{24}\)

\(P = 6\sqrt{4\times 2} +8\sqrt{4\times 5} + 2\sqrt{4\times 6}\)

Evaluate square roots

\(P = 6 \times 2\sqrt{2} +8\times 2\sqrt{5} + 2\times 2\sqrt{6}\)

\(P = 12\sqrt{2} + 16\sqrt{5} + 4\sqrt{6}\)

Hence, the equivalent expressions are:

\(P = 2(4\sqrt{20} + 2\sqrt{24} + 3\sqrt 8)\)

\(P = 2(3\sqrt 8) +2(4\sqrt{20} + 2\sqrt{24})\)

\(P = 12\sqrt{2} + 16\sqrt{5} + 4\sqrt{6}\)

Here we have given that

And we need to determine the approximate speed-up ratio between pipelined and non-pipelined system to execute 100 instructions.

While we looking into the given question we have identified the following values,

=> Number of pipeline segments = stages in pipeline,

=> n = 5

Here we know that,

=> Clock cycle time per operation = clock cycle per stage = 14 ns

And the number of instructions = 100

Here the formula to calculate the startup is written as,

=> T[without pipeline] = no. of instructions × stages in pipeline × clock cycle per stage

=>  100 × 5 × 14

=> T[with pipeline] = (time for pipelined execution without stalls) + (overhead due to stalls)

=> (5 + 99) × 20 + 20 × 20 = 124 × 20

Therefore, the startup is

You purchase a new car today.the value of that car depreciates based on the function f(t)=12,000(0.96)^t, where t is measured in years after purchase. How much is the car worth after 3/2 years, rounded to the nearest dollar

Answers

Considering the definition of exponential function, the value of the car is 11,287.25 dollars.

What is exponential function

An exponential function is one in which the independent variable x appears in the exponent and has a constant a as its base. Its expression is:

f(x)= aˣ

Being a a positive real, a > 0, and different from 1, a ≠ 1.

When 0 < a < 1, then the exponential function is a decreasing function and when a > 1, it is an increasing function.

What is the price of the car

In this case, the value of that car depreciates based on the function f(t)=12,000×\(0.96^{t}\) where t is measured in years after purchase.

After 3/2 years, the value of the car is calculated as:

f(3/2)=12,000×\(0.96^{3/2}\)

Solving:

f(3/2)= 11,287.25

Finally, the value of the car is 11,287.25 dollars.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Each ticket to a concert costs $36.75.

The tickets now cost 0.85 of their original cost.

So, the Sale price of ticket

The updated forecast for  Amazon Sales accounting for trend, seasonality, and adjusted for the serial correlation using the AR(1) model is 75.2432 billion dollars.

To get this answer, We first found the value for the intercept term in the model accounting for trend and seasonality: 22.67 billion dollars.  then added the estimated parameter values for the time period (2.538 billion dollars) and the indicator function for quarter 3 (-8.773 billion dollars). This gave me a total of 16.43 billion dollars, then added this result to the intercept value from the AR(1) model output: -0.0856 billion dollars. This gave me a total of 16.34 billion dollars. Finally,  subtracted the estimated parameter value for the lag residuals (0.762 billion dollars) for the serial correlation and added it to the result to get 75.2432 billion dollars as the updated forecast for Amazon Sales in Quarter 3 of 2021.

Meghan flipped a quarter and rolled a standard six-sided die.

The probability that the coin landed on heads and the die landed on an even number is __%.

Answers

Answer:

25%

Step-by-step explanation:

right on the test

The required probability of the coin landed on heads and the die landed on an even number is 25%.

Given,
Meghan flipped a quarter and rolled a standard six-sided die. The probability that the coin landed on heads and the die landed on an even number is to be determined.

What is probability?

Probability can be defined as the ratio of favorable outcomes to the total number of events.


Sample space of coin = { head, tail } = 2
Sample space for die = { 1, 2, 3, 4, 5, 6 } = 6
favorable outcome for coin  = head = 1
favorable outcome for the die to landed on even number = {2, 4, 6} = 3

Now the probability that the coin landed on heads and the die landed on an even number is,
P = probability of head-on coin * probability of the even number on die
P =  1/2*3/6
P = 1/4
P = 0.25 and 25%

Thus, the required probability of the coin landed on heads and the die landed on an even number is 25%.
