Because t is the number of weeks, replace t with 6 in the equation and solve for s.

s = -0.25(6) +4

s = -1.5 +4

s = 2.5

Now replace t with multiples of 6, use 12 and 18:

s =-.25(12) +4 = 1

s-0.25(18) +4 = -0.5

now fins the difference between the time frames:

2.5 - 1 = 1.5

1 - 0.5 = 1.5

The lengths of the sides of a triangular garden are 10m, 11m, and 13m. find the measure of the angle opposite the longest side t

Zinaida [17]

We know that
applying the law of cosines
c²=a²+b²-2*a*b*cos C

in this problem
a=10 m
b=11 m
c=13 m
C=?

c²=a²+b²-2*a*b*cos C----> cos C=[a²+b²-c²]/[2*a*b]
cos C=[10²+11²-13²]/[2*10*11]----> cos C=0.2364
C=arc cos (0.2364)----> C=76.33°

the answer is
76.3°
