Answer:
61.512
Step-by-step explanation:
Put 14 where x is and do the arithmetic. Arguments for trig functions are always radians unless otherwise specified.
y =18.614 sin(0.521x - 1.984) + 76.900
y =18.614 sin(0.521·14 - 1.984) + 76.900 = 18.614sin(5.31) +76.900
y ≈ 18.614·(-0.82668) +76.900 = -15.388 +76.900
y ≈ 61.512
The regression model predicts y(14) = 61.512.
Answer:
130
Step-by-step explanation:
Supplementary angles are angles that are equal to 180 degree so if one is 50 degrees then the other must be added to it and get 180
180= 50 + ∠4
-50 -50
130=∠4
Answer:
5859375
Step-by-step explanation:
These are the terms of a geometric sequence with n th term
= 
where r is the common ratio and the first term
here r = 
= 
= 
= 5 and = 3, hence
= 3 × 
= 5859375
Answer:
4/7 > x > -11/7
Step-by-step explanation:
First, add -4/3 to all parts
then divide all parts by -7/3
Answer:
