Answer:
a(n) = 1 + 7(n-1)
Step-by-step explanation:
In a triangle, the nomenclature is that a variable side a is opposite of the angle A. we can use the cosine law to determine the value of cosine A.
a2 = b2 + c2 -2bc cos a25 = 36 + 64 - 2*6*8 * cos acos a = 25/32
Answer:
C
Step-by-step explanation:
subtract 5 from both sides
y = 7
x = 4 is a vertical line parallel to the y- axis passing through all points with an x- coordinate of 4
A line perpendicular to x = 4 will be a horizontal line parallel to the x- axis with equation y = c where c is the value of the y- coordinate the line passes through.
line passes through (5 , 7) with y- coordinate 7
The equation is therefore y = 7
Answer:
140
Step-by-step explanation:
We can find the number of houses from ...
# houses = (houses/flats)(flats/bungalows)(# bungalows)
= (7/4)(8/5)(50)
# houses = 140
