Answer:
Option B is correct.
Initial amount (a) = 30 and growth factor(b) = 8.3
Step-by-step explanation:
An exponential function is of the form: ....[1]
where
a represents the initial amount
b represents the growth factor and x is the variable
Given the function:
On comparing given equation with [1] we get;
a = 30 and b = 8.3
Therefore, the initial amount(a) = 30 and growth factor(b) = 8.3
Answer:
<em>35.11 ft</em>
<em></em>
Step-by-step explanation:
This given situation can be thought of as triangle where PQ is the length of pole.
PR is the length of rope.
and QR is the distance of bottom of pole to the point of fastening of rope to the ground.
And
Given that:
PQ = 44 ft
PR = 51 ft
To find:
Side QR = ?
Solution:
We can apply Sine Rule here to find the unknown side.
Sine Rule:
Where
a is the side opposite to
b is the side opposite to
c is the side opposite to
Now,
Let us use the Sine rule again:
So, the answer is <em>35.11 ft</em>.
