Set 500 to sum of distances traveled by both cars.
26)
the sum of all internal angles=(sides-2)*180
720=(x/25-2)*180
4=x/25-2
6=x/25
150=x degrees per angle of A
use angle of A to calculate amount of sides of A:
150=(n-2)*180/n
150=180-360/n
360/n=30
12=n=sides of A
-> F
27)
Donald=500-6*t
Wendy=400-4*t
W=D
500-6t=400-4t
100-6t=-4t
100=2t
50=t
-> A
Answer:
3 1/2 gallons.
Step-by-step explanation:
1 6/16 + 2 1/8
= 3 + 6/16 + 1/8
= 3 + 3/8 + 1/8
= 3 4/8
= 3 1/2 gallons.
I guess when you say you want a cartesian equation of the curve, you would have to express them in cartesian coordinates of x and y. Thus, you must get rid of the variable t. The solution is as follows:
x = t⁴
y = ln(t)
e^y = e^(lnt)
e^y = t
Substuting this to the first equation,
x = (e^y)⁴
<em>x = e^4y</em>
