hoa [83]

Answer:

Correct option: (3) 45

Step-by-step explanation:

Let's call the length of the tangent 'T', the length of the external segment 'E' and the length of the internal segment 'A'.

If we have a secant and a tangent to a circle, we can use the following property:

T^2 = E * (A + E)

If the tangent is 14 inches and the external segment is 4 inches, we have that:

14^2 = 4 * (A + 4)

196 = 4A + 16

4A = 180

A = 45

Correct option: (3)

!!!!!!!!HELP PLEASE!!!!!!!!       In ΔSTU, SU = 18 and TU = 13. Find m∠T to the nearest tenth of a degree.
tatyana61 [14]
We can use a trig function to find the measure of angle T.

tan(T) = 18/13

Take the archtangent on both sides since we are searching for an angle.

arctan(tan T) = arctan(18/13)

T = 54.16°

The measure of angle T is 54.16°.

Andre45 [30]

Answer:

  • Growth
  • 22%

Step-by-step explanation:

<u>Given function:</u>

  • P(t) = 400(1.22)^{t}

<u>Initial population size is when t = 0</u>

  • P(0) = 400(1.22)⁰ = 400(1) = 400

<u>The multiple of 1.22 is applied every year, so the ratio of change is:</u>

  • 1.22 = 122% = 100% + 22%

This is an exponential growth which represents 22% annual growth.
