Answer:
Distance traveled= 41968.4 km
The domain of the function is t
t(h)= 478
h = hours
Step-by-step explanation:
the distance that they traveled in kilometers, d, can be modeled by
d(t) = 97.8t
where t is the time in hours
They traveled a total of 478 hours.
Distance traveled d(t)
d(t) = 87.8(478)
d(t) = 41968.4
Distance traveled= 41968.4 km
The domain of the function is t
t(h)= 478
Sin time secant = sin(x)*1/cos(x) = tan(x)!!
Answer:
24m
Step-by-step explanation:
Applying the centroid theorem, the length of QR is: 12.
<h3>What is the Centroid Theorem?</h3>
- According to the centroid theorem, the centroid (the point where the three medians intersect) is 2/3 of the distance from the midpoint of the a side to each vertex opposite vertex of the triangle.
Given:
QU = 8
QU = 2/3(QR)
8 = 2/3(QR)
3(8) = 2(QR)
24 = 2(QR)
QR = 12
Therefore, applying the centroid theorem, the length of QR is: 12.
