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
AB²=BD*BC
BD=12
BC=12+15----> BC=27
AB²=12*27----> 324
AB=√324----> AB=18
the answer is
AB=18 units
Step-by-step explanation:
(2.6 X 10⁵)²
=6.76×10¹⁰
<span><span>Okay, so let's start by setting up this problem:
</span>(original number=x)(percentage=.06)=(percentage of original number)</span>
So it should look like this:
<span>(x)(.06)=51 Now we should divide .06 from each side
</span><span>x=850 And there we go! 850 is the answer.
i hope this help

Answer:
P(t)= 100t + 150
Step-by-step explanation:
If the price for 6 hours of studio time is 600 dollars, that means every hour the studio is used it costs 100 dollars. Since the fixed fee is 150 dollars, that is added to the cost of how many hours the studio is used.
I hope this helped you. If it did Brainilest is appreciated.
Answer:
a. x - cd = 0
b. d = 1 / 2
Step-by-step explanation:
d = 2
c = 7
a.
c is inversely proportional to d,
c ∝ 1 / d
This inversely proportional need to be removed by using a variation / variable.
Let the variable be " x ".
c = x / d
Multiply d on both sides,
cd = x
x = cd
Subtract cd on both sides,
x - cd = 0
Hence, the equation is " x - cd = 0 ".
b.
By using the equation,
x - cd = 0
Add cd on both sides,
x = cd
c = 17, d = 2
x = 17 * 2
x = 34
To find d, when c = 68.
x = cd
34 = 68 * d
Divide 68 on both sides,
34 / 68 = d
1 / 2 = d
d = 1 / 2
