Your answer would be r = 12/7 ≈ 1.71
Firstly you need to write an equation involving r and t. They tell you that r varies inversely with t, which means r = k/t, where k is some constant.
We can find k by substituting in the values for r and t that they give us:
r = k/t
2 = k/(-6)
-12 = k
Now the equation is r = -12/t. We can then substitute in t as -7 to get the final answer:
r = -12/t
r = -12/(-7)
r = 12/7 ≈ 1.71
I hope this helps!
The answer is no solution
Answer:
5. Slope = -2x
(Full system: y = -2x + 5)
6. Slope = -1/2x
(Full system: y = -1/2 +6)
See the attached figure
Let
h---------> building tall
we know that
tan 74°=h/34---------> h=34*tan 74°--------> 34*3.487------> 118.57
h=118.6 ft
the answer is h=118.6 ft
