Answer:
a
Step-by-step explanation:
Given:
m∠APB = 74°
To find:
The measure of ACB
Solution:
The measure of the central angle is congruent to the measure of the intercepted arc.
⇒ m(ar AB) = m∠APB
⇒ m(ar AB) = 74°
The complete angle of the circle is 360°.
⇒ m(ar ACB) + m(ar AB) = 360°
⇒ m(ar ACB) + 74° = 360°
Subtract 74° from both sides.
⇒ m(ar ACB) = 286°
The measure of arc ACB is 286°.
Let x = the number of hours since 5 a.m.
Let y = temperature, °F
Let the total temperature change be modeled by the expression
y = ax + b
At 5 a.m., x = 0 and y = -9.4°F. Therefore
b = -9.4
When x = 6 hours, y = 2.8°F. Therefore
6a + b = 2.8
6a - 9.4 = 2.8
6a = 12.2
a = 2.0333
The expression is
y = 2.0333x - 9.4
Answer:
y = 2.0333x - 9.4
where
x = hours since 5 a.m.
y = temperature, °F
