A 3n = $3.85
Step-by-step explanation:
For every 3 pounds of butter you have, you have to pay $3.85
the equation is = 3n = $3.85
Answer:
Step-by-step explanation:
<u>Find the m∠B:</u>
- m∠B = (360° - 310°) + 50° = 100°
a)
<u>Find AC using law of cosines:</u>
- AC = √(8² + 13² - 28*13*cos 100°) = 16.4 km (rounded)
b)
<u>Find m∠A using law of sines:</u>
- 16.4/ sin 100 = 13 / sin A
- m∠A = arcsin (13 sin 100 deg / 16.4) = 51° (rounded)
<u>The bearing of C from A:</u>
c)
<u>Let the required distance is x:</u>
- x/ BC = sin 50°
- x = BC sin 50°
- x = 13 sin 50°
- x ≈ 10 km (rounded)
Answer:
The equation has zeroes at -4, 0 and 4 and is a minimum cubic degree or a 3 degree equation.
Step-by-step explanation:
The polynomial has roots at places where f(x) cuts the x axis.
The function cuts the x-axis at 3 points: 4, -4, and 0.
It cuts the axis at the point, x=0; x=4; x=-4
Therefore, the points equation has to be of the form, k*x*(x-4)*(x+4)*p(x)
where k is any arbitrary constant and p(x) is a polynomial of any degree depending on what the equation does in the region and (5,∞) and (-∞,-5).
Therefore, the equation has zeroes at -4, 0 and 4 and is a minimum cubic degree or a 3 degree equation.
