F(x)=-7x-6
Initial value=f(0)
f(0)=-7(0)-6
=-6
-5 + 19 = 14
-5 - 19 = -24
14,-24
I’m pretty sure the answer is B) d= 3.2t
Because 3.2 is basically 3.20. And 3.20 is basically 320. If you subtract that by the distance, it would be less than 320.
I think this is the answer but if it isn’t I’m sorry. But I think it is B

Answer: 0.02, 0.021, 0.12, 0.2
Answer:
11.28m
Step-by-step explanation:
The computation of the height of the spire is shown below:
let us assume the height of the spire be x
Now
For triangle ABD
Tan 43 degrees = h ÷ x
x = h × cot 43 degrees
= 1.07236 h
For triangle ABC
tan 15 degrees = h ÷ (30 + x)
0.2679 = h ÷ 30 + 1.07236h
8.038 + 0.28728 h = h
h = 11.28m
