Answer: 36 intersections
Step-by-step explanation:
Answer:
A = 36.8°
B = 23.2°
a = 7.6
Step-by-step explanation:
Given:
C = 120°
b = 5
c = 11
Required:
Find A, B, and a.
Solution:
✔️To find B, apply the Law of Sines

Plug in the values

Cross multiply
Sin(B)*11 = sin(120)*5
Divide both sides by 11


Sin(B) = 0.3936
B = 
B = 23.1786882° ≈ 23.2° (nearest tenth)
✔️Find A:
A = 180° - (B + C) (sum of triangle)
A = 180° - (23.2° + 120°)
A = 36.8°
✔️To find a, apply the Law of sines:

Plug in the values

Cross multiply
a*sin(23.2) = 5*sin(36.8)
Divide both sides by sin(23.2)

a = 7.60294329 ≈ 7.6 (nearest tenth)
A quadratic equation is set up in the form of ax² + bx +c
First set equation = to 0
0= x² - 5x - 24
Next plug into quadratic formula( -b Plus or minus the √b²-4ac) ÷ 2a
[10 plus or minus √(25² - 4×1×24)] ÷ 2
Solve for inner parenthesis first
√625- 96 = √529
Now set up two equations
(10 + √529) ÷2 = x = 16.5
(10 - √529) ÷2 = x = -6.5
So therefore x = 16.5 and -6.5
I pretty sure the best answer would be f(x)=cbrt(27-x)
cbrt means cube root by the way.
