The slope-intercept form:
m - slope
b - y-intercept → (0, b)
We have the point (0, 5). Therefore b = 5.
We have: y = mx + 5
Other point (3, 2). Substitute the coordinates of the point to the equation of the line:
<em>subtract 5 from both sides</em>
<em>divide both sides by 3</em>
<h3>Answer: f(x) = -1x + 5 = -x + 5</h3>
25 a² + 20 ab + 4 b²
for formula
find u,v such that: u.v = a
and u+v = b then group according to
=
factor out 5a from :
factor out 2b from :
=
factor out :

Answer:
189,2$
Step-by-step explanation:
220*0,86=189,2
14% = 14/100 = 0,14
1-0,14 = 0,86
price* factor between 0 and 1, 0 -> item is free, 1 -> full price
Asnswer:
Step-by-step explanation:
Firstly we calculate length of CB
/CA/^2 = /BA/^2 + /CB/^2
12^2 = 6^2 + /CB/^2
144 = 36 + /CB/^2
/CB/^2 = 144 - 36
/CB/^2 = 108
/CB/ = √108
/CB/ = 10.4cm
Sin55 = (/CB/)/(/CD/)
Sin55 = 10.4/(/CD/)
/CD/ = 10.4/sin55
/CD/ = 12.7cm
Step-by-step explanation:
4.6+4.6=8.12
8.1 to one decimal place
the radius is half the length.
