Point X outside a circle is 34 cm from the center of the circle.
scoundrel [369]

Answer:

Right option is c 16 cm

Step-by-step explanation:

From the question,

The radius of the circle, the point drawn from the center of the circle to piont X and the length of the tangent drawn from point X to the point of tangency all form a right angle triangle.

Using pythagoras theorem,

a² = b²+c²...................... Equation 1

Where b = the length of the tagent, a = length of the point drawn outside the circle from the center, b = radius of the circle.

Given: a =  34 cm, b = 30 cm.

Substitute into equation 1

34² = 30²+c²

c² = 34²-30²

c² = 1156-900

c² = √256

c² = 16 cm.

Hence the right option is c 16 cm

If $190 is invested at an interest rate of 11% per year and is compounded continuously, how much will the investment be worth in
dangina [55]

Answer:

$295.01

Step-by-step explanation:

Using the compounding continuously formula, we are looking for A.  We have that P = 190; r = .11 (always use the decimal form of the rate!); and t = 4.  Filling in we have:

A=190e^{(.11)(4)}

Simplifying that multiplication:

A=190e^{.44}.

On your calculator, raise e to the .44 power to get

A = 190(1.552707219) and

A = $295.01
