In circle O, BC=14 and DC=25. What is the length of diameter BA? -58.6 -12.2 -44.6 -30.6
1 answer:
The picture in the attached figure
we know that
If a tangent segment and a secant segment are drawn to a <span>circle </span><span>from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment
</span>so
DC²=BC*CA-----> CA=DC²/BC
DC=25
BC=14
CA=25²/14-----> CA=44.64
CA=BC+BA----> BA=CA-BC----> BA=44.64-14----> BA=30.64
BA is the diameter
hence
<span>the length of diameter BA is 30.64----> round to the nearest tenth---> 30.6
</span>
the answer is
<span>the length of diameter BA is 30.6</span>

Answer:
339 miles.
Step-by-step explanation:
Given:
A car rental agency advertised renting a car for $27.95 per day and 0.26$ per mile.
If Trevor rents this car for 4 days.
Question asked:
How many whole miles can he drive on a $200 budget?
Solution:
Total budget = $200
Trevor rents car for number of days = 4
As a car rental agency renting a car for $27.95 per day fixed charge, so Trevor must pay = Fixed charge per day number of days rented for
= $27.95 4
= $111.8
Remaining amount = $200 - $111.8 = $88.2
Now, to find number of miles he can travel, we will divide remaining amount by amount charged per mile
$88.2 $0.26 = 339.23 miles
Therefore, he can drive 339 miles on a $200 budget
