Answer:
14,1 cm
Step-by-step explanation:
If a circle passes through the vertices of a square then the diagonal of a square is a circle diameter.
We use Pytagoras Theorem to find out the length (L) of the diagonal given that:
L² = (20)² + (20)²
L² = 2* (20)²
L = √2 * 20
L = 1,4142* 20
L = 28,28 cm
L diagonal in the square is a diameter of the circle then radius of a circle is:
r = L/2 ⇒ r = 28,28 /2 ⇒ r = 14,14 cm
Answer:
No
Step-by-step explanation:
In order for there to be a right triangle formed, this must satisfy pythagoran's theorm thingy:
a^2+b^2=c^2
7^2+15^2=274
22^2= 484
since 274 isnt equal to 484
There is not a right triangle formed here
Answer: 2 units left and 3 units up
Step-by-step explanation:
12/12 possibility for getting a number on a dice
With 2 dice, there would be 24 possible outcomes (double 12)
Answer:
h(x) = 0.0045x – 0.4
Step-by-step explanation:
The length of time in hours of two airplane flights are represented by the following functions, where x is the number of miles for the flight.
Flight A: f(x) = 0.003x - 1.2
Flight B: g(x) = 0.0015x + 0.8
Then the function
h(x) = f(x) + g(x) = (0.003 + 0.0015)x + (-1.2 + 0.8) = 0.0045x - 0.4.
Therefore, the third option is the right option. (Answer)
