Answer:
-3/2
Step-by-step explanation:
Parallel lines have equal slopes.
Y decreased by 23 is 52.9....
y - 23 = 52.9 <== ur equation
y = 52.9 + 23
y = 75.9
================
c - 12 = 6 <== ur equation
c = 6 + 12
c = 18
================
h - 234 = 1192
h = 1192 + 234
h = 1426
no, he is not correct because he did not add 234 and 1192 to find the value of h, which is 1426
Answer:
the like terms here are the x and the + symbol.
Step-by-step explanation:
If a part of the equation appears more than once that is a like term.
Answer:
71.6 degrees
Step-by-step explanation:
Given the vectors
u= <8,4> v = <9.-9> (5 points)
u*v = (8, 4)*(9, -9)
u*v = 8(9)+(4)(-9)
u*v = 72 - 36
u*v = 36
|u| = √8²+4²
|u| = √64+16
|u| = √80
|v| = √9²+9²
|v| = √81+81
|v| = √162
Using the formula
u*v = ||u||v| cos theta
36 = √80(√162)cos theta
36 = √12960 cos theta
cos theta = 36/√12960
cos theta = 36/113.8
cos theta = 0.3162
theta = arccos(0.3162)
theta = 71.56 degrees
Hence the angle between the given vectors to the nearest tenth of a
degree is 71.6 degrees
