Answer:
TS = 6.6 (nearest tenth)
Step-by-step explanation:
<u>Secant</u>: a straight line that intersects a circle at two points.
<u>Tangent</u>: a straight line that touches a circle at only one point.
<u>Theorem</u>
When a secant segment and a tangent segment meet at an exterior point, 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.
Given:
- Tangent segment = QR
- Secant segment = TR
- External secant segment = SR
⇒ QR² = TR · SR
⇒ 19² = (TS + 16) · 16
⇒ 361 = (TS + 16) · 16
⇒ 22.5625 = TS + 16
⇒ TS = 22.5625 - 16
⇒ TS = 6.5625
⇒ TS = 6.6 (nearest tenth)
114/6 = 19 parts per minute
19 * 15 = 285 parts
hope this helps.
Answer:
Exponential decay
Step-by-step explanation:
Because the values are exponentially decreasing.
Answer:
A
Step-by-step explanation:
Solving for y in the second equation is the best way because it will leave you with a direct equation of y = _______
This will allow for you to solve with substitution.
