Answer:
Answer: A
Step-by-step explanation:
From the table given, the data sets are such that set A is a linear function while data set B is follows an exponential function. Given that the range of data set A over the same domain is smaller that the range of data set B over the same domain. Hence we conclude that the set A is linear and the values increase at a slower rate than set B.
speed of plane flying east = x
speed of plane flying west = x+75
total speed = 2x+75
distance after 4 hours ( 7-3) = 8x+300
8x+300 = 5460
8x = 5160
x = 5160/8 = 645
speed of plane flying east = 645 km/h
Answer:
tan(B)
Step-by-step explanation:
we know that
The tangent of an angle is equal to divide the opposite side to the angle by the adjacent side to the angle
In this problem
tan(B)=AC/AB
substitute
tan(B)=8/15
The sides are in the ratio 1 : 1 : sqrt2 where sqrt 2 = hypotenuse
so if the length of one of the legs is 2 cm the hypotenuse will be of length 2 *sqrt 2 cms.
b ) sin 45 = 1 / sqrt2 = sqrt2 / 2
c) if the 2 legs of triangle are both 2 cms area will be 1/2* 2* 2
Answer:
0.75m/s
Step-by-step explanation:
speed = d/t
