The area of the square is 100 square centimeters. What is the area of the circle?
swat32

Answer:

  • Since the question is incomplete, see the figure attached and the explanation below.

Explanation:

Since the figure is missing, I enclose the figure of a square inscribed in a circle.

Since the <em>area of a square</em> is the side length squared, you can determine the side length:

  • Area = (side length)²
  • 100 cm² = (side lenght)²

        side\text{ }length=\sqrt{100cm^2}=10cm

From the side length, you can find the diagonal of the square, which is equal to the diameter of the circle, using the Pythagorean theorem:

  • diagonal² = (10cm)² + (10cm)² = 2 × (10cm)²

         diagonal=\sqrt{2\times (10cm)^2}\\ \\ diagonal=10\sqrt{2} cm

The area of the circle is π (radius)².

  • radius = diameter/2 = diagonal/2

        area= \pi \times (5\sqrt{2}cm)^2=50\pi cm^2

Suppose m = 2 + 6i, and | m + n | = 3√10, where n is a complex number.
Ksju [112]

Answer: a) √50

b) n = 1 + 7i

Step-by-step explanation:

first, the modulus of a complex number z = a + bi is

IzI = √(a^2 + b^2)  

The fact that n is complex does not mean that n doesn't has a real part, so we must write our numbers as:

m = 2 + 6i

n = a  + bi

Im + nI = 3√10

Im + n I = √(a^2 + b^2 + 2^2 + 6^2)= 3√10

            = √(a^2 + b^2 + 40) = 3√10

             a^2 + b^2 + 40 = 3^2*10 = 9*10 = 90

             a^2 + b^2 = 90 - 40 = 50

            √(a^2 + b^2 ) = InI = √50

The modulus of n must be equal to the square root of 50.

now we can find any values a and b such a^2 + b^2 = 50.

for example, a = 1 and b = 7

1^2 + 7^2 = 1 + 49  = 50

Then a possible value for n is:

n = 1 + 7i

ILL GIVE BRAINLIEST AND CRAZY POINTS JUST HELP!!!
kvasek [131]

Charter Bus:

1.

350 ( distance) / 50 ( rate)  = 7 (time in hours).

Conclusion - Will take the charter bus 7 hours to drive from Norfolk to New York.

2.

12  - 6  = 6 A.M  ( counting for time left in this half of the day)

7 - 6 = 1 hour left ( which will be then 1 P.M )

Conclusion- Will arrive in New York City at 1 P.M.

Personal Vehicle:

3.

1 hour : 70 miles, 2 hours : 140 miles, 3 hours : 210 miles, 4 hours : 280 miles,     5 hours : 350 miles.

Conclusion: It will take 5 hours to get to New York City from Norfolk.

4.

12 A.M - 7:30 A.M = 4:30 A.M

5 - 4.5 = 0.5 hours left ( which will be then 12:30 P.M )

Conclusion- Will arrive in New York City at 12:30 P.M.

Meet Up:

5. By looking at the rates/ratios of both vehicles and finding out the time it would take with both vehciles also I figured out that Dakota's parents will arrive first.

I didn't include a graph, I thought that you could do that with the rates of both vehicles.
