Answer:
C= 15
Step-by-step explanation:
subtracting 32 from both sides
Dividing both sides by 9/ 5
Answer:
- discriminant: 11
- solutions: -6, +5
Step-by-step explanation:
Comparing your equation to the standard form, we can find the values necessary to compute the discriminant:
x^2 +x -30 = 0
ax^2 +bx +c = 0
So, we have ... a = 1, b = 1, c = -30
The discriminant is defined as ...
d = √(b² -4ac) = √(1² -4(1)(-30)) = √121
d = 11
The solutions are ...
x = (-b ± d)/(2a) = (-1 ±11)/2
x = {-6, +5}
Answer:
If this is the question about sample space, a possible answer is 24 and 64 ways in sample space.
Step-by-step explanation:
Hopefully, this is helpful :)
When we get tangents or secants or a combination intersecting outside the circle, the intersection angle is half the difference of the arcs.
Here that means C = (1/2) ( arc AE - arc BD)
The total around the circle is 360 degrees so
arc AE = 360 - (25 + 115 + 115) = 105 degrees
C = (1/2) ( 105 - 25 ) = 40 degrees
Answer: B, 40 degrees
