Answer:
48
Step-by-step explanation:
52+59=111 180-111=69 69+63=132 180-132=48
Answer:
t=9
Step-by-step explanation:
5t-21.4=23.6
1) Start by adding 21.4 to both sides:
5t=45
2) Divide by 5 on both sides:
t=9
Answer:
The answer w'll be obtained using formulas
cos(a+b) = cosacosb - sinasinb
cos(a-b) = cosacosb + sinasinb
Step-by-step explanation:
Using the trigonometric formula of addition and subtraction of cosine
cos(a+b) = cosacosb - sinasinb
cos(a-b) = cosacosb + sinasinb
w'll get the desired answer.
To be solve
L.H.S = R.H.S
sinasinb = (cos(a-b)-cos(a+b)/2
as we know that <u><em>cos(a+b) = cosacosb - sinasinb</em></u>
sinasinb = (cos(a-b) - (cosacosb -sinasinb))/2
as we know that <u><em>cos(a-b) = cosacosb + sinasinb</em></u>
sinasinb = ((cosacosb + sinasinb) - (cosacosb -sinasinb))/2
sinasinb = (cosacosb + sinasinb - cosacosb + sinasinb)/2
sinasinb = (2sinasinb)/2
sinasinb = sinasinb
hence L.H.S = R.H.S
You need to post the equations.
I could make a guess and say the equation is:
(x-8)*(x+2) = 0
x^2 -6x -16 = 0
and to have a y-intercept of -48, it should be:
4x^2 -24x -48 = 0
