Answer
y=17x+55
Step-by-step explanation:
Answer:
a) x=25+0.06y
b)x=25+0.06*30=£26.80
c)x=25+0.06*200=£37
d)x=25+0.06y ; 43=25+0.06y ; 43-25=0.06y ; 18=0.06y ; y=18÷0.06 ; y=300 messages
Step-by-step explanation:
aaaaaa hope theyre correct
Gradient = 7-(-1)/4-3
= 8
when x = 3, y = -1,
y = 8x + c
-1 = 8(3) + c
c = -1 - 24
= -25
the equation of the line is y = 8x - 25.
Answer:
a) 0∘ and 360∘
b) 300∘ and 60∘
c) 90∘ and 270∘
d) 180∘
Step-by-step explanation:
θ(0<=θ<=360∘)
then
a)
F=1/2(1−cosθ)
Putting F= 0
we get
0 = 1/2 (1−cosθ)
(1−cosθ) = 0
cosθ = 1
θ =
(1)
= 0∘ and 360∘
b) If F = 0.25
then putting values
1/4 = 1/2 (1−cosθ)
(1−cosθ) = 1/2
cosθ = 1/2
θ =
(1/2)
= 300∘ and 60∘
c) If F = 0.5
then putting values we get
1/2 = 1/2 (1−cosθ)
(1−cosθ) = 1
cosθ = 0
θ =
(0)
= 90∘ and 270∘
d) If F = 1
then putting values we get
1 = 1/2 (1−cosθ)
(1−cosθ) = 2
cosθ = -1
θ =
(-1)
= 180∘
So after these calculation we determine the vales of angles that are given uper.
Answer:
33
Step-by-step explanation:
Given
6x + 3 - 10 + y
= 6x - 7 + y ← substitute x = 7 and y = - 2 into the expression
= 6(7) - 7 + (- 2)
= 42 - 7 - 2
= 33
