Applying the secant-tangent theorem, the length of diameter, BA is: A. 52.9.
<h3>What is the Secant-Tangent Theorem?</h3>
Considering the image given, the secant-tangent theorem states that:
DC² = (BC)(BA)
Given the following:
Substitute the values into the equation
30² = (17)(BA)
900/17 = BA
BA ≈ 52.9
Length of the diameter, BA is: A. 52.9

Answer:
$133.20
Step-by-step explanation:
Since the amount of hours she worked isn't a whole number, we can first separate 18 and 1/2 and work the problem out one at a time.
1. Multiply 7.20 by 18 to get 129.60
2. Multiply 0.50 by 7.20 to get 3.60.
3. Add 129.60 and 3.60 together to get the answer, 133.20.

Step-by-step explanation:
Set A
P - 396 = t <== ur equation
a + b = 88 <span>
<span>
</span><span>ab = y
</span><span>
</span><span>a = 88 - b
</span><span>
</span><span>y = (88 - b)*b
</span>
<span>y = -b^2 + 88b
</span><span>
</span><span>Take the derivative and set equal to 0
</span><span>
</span><span>y' = -2b + 88 = 0
</span><span>
</span><span>2b = 88
</span>
<span>b = 44 </span></span>
<span><span>a=44</span></span>
<span><span> both numbers are 44</span></span>
