Answer:

144m²

Step-by-step explanation:

area is equal to side×side

side=12

=12×12

=144m²

Answer:

[tex]144m^{2}[/tex]

Step-by-step explanation:

Square = length * width

As everyone knows that the length and width of a square are the same, 12 times 12 equals 144.

We have

[tex]\sqrt[k]{\Gamma\left(\dfrac1k\right) \Gamma\left(\dfrac2k\right) \cdots \Gamma\left(\dfrac kk\right)} \\\\ = \exp\left(\dfrac{\ln\left(\Gamma\left(\dfrac1k\right) \Gamma\left(\dfrac2k\right) \cdots \Gamma\left(\dfrac kk\right)\right)}k\right) \\\\ = \exp\left(\dfrac{\ln\left(\Gamma\left(\dfrac1k\right)\right)+\ln\left( \Gamma\left(\dfrac2k\right)\right)+ \cdots +\ln\left(\Gamma\left(\dfrac kk\right)\right)}k\right)[/tex]

and as k goes to ∞, the exponent converges to a definite integral. So the limit is

[tex]\displaystyle \lim_{k\to\infty} \sqrt[k]{\Gamma\left(\dfrac1k\right) \Gamma\left(\dfrac2k\right) \cdots \Gamma\left(\dfrac kk\right)} \\\\ = \exp\left(\lim_{k\to\infty} \frac1k \sum_{i=1}^k \ln\left(\Gamma\left(\frac ik\right)\right)\right) \\\\ = \exp\left(\int_0^1 \ln\left(\Gamma(x)\right)\, dx\right) \\\\ = \exp\left(\dfrac{\ln(2\pi)}2}\right) = \boxed{\sqrt{2\pi}}[/tex]

Answer:

7.716 (with margin: 0.001)

Step-by-step explanation:

speed = distance ÷ time

For speed to be at a minimim you need distancemin ÷ timemax

Min distance = 345 - 0.5 = 344.5m

Max Time = 44.6 + 0.05 = 44.65 sec

speedmin=344.5 ÷ 44.65 = 7.7155..... = 7.716 m/s (3 dp)

The slowest speed possible of the athlete is required.

The minimum possible speed of the runner is 7.7 m/s.

d = Distance run by the athlete = 345 meters

t = Time taken by the athlete to cover the distance = 44.6 seconds

Speed is given by

[tex]s=\dfrac{d}{t}[/tex]

[tex]s=\dfrac{345}{44.6}[/tex]

[tex]s=7.735\approx 7.7 \text{m/s}[/tex]

The speed of the athlete should be at least 7.7 m/s any less than that and the athlete will not be able to cover the required distance in the given time.

Answer:5x because ie d ecaied d

Answer:

A. 3x + (x+8) = -22 - 2x

Step-by-step explanation:

Let the number equal x.

Set up the first half of the equation.

The sum of three times the number and 8 more than the number can be written as:

3x + (x+8)

Sum means that you add the components.

Set up the second half of the equation.

The difference between -22 and twice the number can be written as:

-22 - 2x

Difference means subtraction, and because -22 is written first, that is the number that you subtract from.

If you set the halves of the equation equal, you get:

3x + (x+8) = -22 - 2x

Therefore, the answer is A.

Answer:

Both trains will meet at 2.2 hours (2 hours and 12 minutes).

Step-by-step explanation:

Relative Speed

If two moving objects are traveling through the same line and have speeds v1 and v2 respectively, their relative speed is vr = v1-v2.

Both trains travel toward each other, which means their speeds are of opposite signs.

Let's assume the first train has a positive speed of 65 mph, and the second train has a negative speed of -85 mph. Then, the relative speed is vr = 65 + 85 = 150 mph.

To calculate the time they take to meet, we apply the formula:

[tex]\displaystyle t=\frac{x}{vr}[/tex]

[tex]\displaystyle t=\frac{330}{150}=2.2\ hours[/tex]

Both trains will meet at 2.2 hours (2 hours and 12 minutes).

Step-by-step explanation:

Ten years ago, the city's population was 249,583. Its current population is 318,270. By about 28% has the city grown over the past ten years. [ Solution: Population of the city before 10 years = 249583; Current population = 318270; Population grown =318270-249583 = 68687; 68687/249583 = 0.2752; 0.2752 x 100 = 27.52%. ]

Answer: It doubles

Step-by-step explanation:

Inflation erodes the value of a currency thereby reducing the purchasing power that customers have as they will only be able to buy less gods and services for the same amount as before.

An increase in inflation is directly proportional to a decrease in purchasing power which means that if the inflation rate doubles, the decrease in purchasing power doubles as well.

For instance, if inflation is 10%, the value of a dollar becomes 0.9c. If Inflation doubles to 20%, the dollar goes to 0.8c. Meanwhile the purchasing power would have gone from $1 to 0.8c which would translate to a 20% decrease.
