Theta=0.849978 or 0.85 (I guess this is in radian form)
Converting it to degrees I think it is 0.85 = 48.70 degrees
48.70 does not equal 34.38 degrees so false right?
<span>I think the answer is false. </span>
The new crew works at the rate 1/12 apt/hr.
The old crew works at the rate 1/6 apt/hr.
Let x = hours required to paint the apartment when the two crews work together.
That is,
(1/12 + 1/6 apt/hr)*(x hr) = (1 apt)
(3/12)x = 1
(1/4)x = 1
x = 4 hours
Answer: 4 hours
Answer:
5 : 12
Step-by-step explanation:
Cheerleaders : football players
20 : 48
5 : 12
The answer
ellipse main equatin is as follow:
X²/ a² + Y²/ b² =1, where a≠0 and b≠0
for the first equation: <span>x = 3 cos t and y = 8 sin t
</span>we can write <span>x² = 3² cos² t and y² = 8² sin² t
and then </span>x² /3²= cos² t and y²/8² = sin² t
therefore, x² /3²+ y²/8² = cos² t + sin² t = 1
equivalent to x² /3²+ y²/8² = 1
for the second equation, <span>x = 3 cos 4t and y = 8 sin 4t we found
</span>x² /3²+ y²/8² = cos² 4t + sin² 4t=1
