Answer:
3/16
Step-by-step explanation:
The radii of the three circles appear to be in the ratios ...
5 : 10 : 20 = 1 : 2 : 4
Then the areas of the circles will be in the ratios that are the square of these:
1 : 4 : 16
The shaded area is the area of the middle-sized circle, less the area of the smaller circle, so is 4-1 = 3 "ratio units". The ratio of that area to the area of the largest circle is the probability of randomly choosing a point in the shaded area:
p(shaded) = 3/16
For this you do Pythagorean theorem so
7^2+12^2=x^2
49+144=x^2
193=x^2
x=squareroot193
so you put 193 in the green box.
hope this helped❤️

Area =
Answer:
(x = -11 and y = 56) or (x = 1 and y = -4)
Step-by-step explanation:
The equation of the parabola is 10 + y = 5x + x² ........(1)
And 5x + y = 1 ....... (2) is the straight line.
We have to find solutions to equations (1) and (2).
Now, solving equations (1) and (2) we get, 10 + (1 - 5x) = 5x + x²
11 - 5x = 5x +x²
x² + 10x - 11 = 0
(x + 11) (x - 1) = 0
Hence, x = -11 or x = 1
Now, from equation (2),
y = 1 - 5x = 1 - 5(-11) = 56 {When x = -11}
And, y = 1 - 5(1) = -4 (When x = 1}
Therefore, the solution of the system are (x = -11 and y = 56) or (x = 1 and y = -4) "Answer"
All done
The factor of the will be 3(3x-5)(2x+1).
<h3>What will be the factor of
?</h3>
Given quadratic equation is
By taking 3 common from whole of the equation it becomes.
now by factorization equation will be.
3[(2x(3x-5)+1(3x-5)]
Taking (3x-5) common from whole equation it will become
3(3x-5)(2x+1).
Hence the factor of the will be 3(3x-5)(2x+1).
To know more about factorization follow.
