Answer:
You simply take the values away from 180°.
a) 180-85-65 = 30°
b) 180-37-63=80°
c) 180-52-78=50°
d) 180-102-58=20°
e) 180-100-60=20°
f) 180-105-25=50°
g) 180-127-23=30°
Answer:
True.
Step-by-step explanation:
Given,
4cos2 (4x) - 3 = 0
Now, 4π/24 = π/6
Or, cos π/6 = √3/2
Or, cos^2 π/6 = 3/4
Or, 4 cos^2 π/6 = 3
Now, Left Hand Side= 4cos2 (4x) - 3
= 3-3 =0 = Right Hand Side (Proved)
Here, Left Hand Side= Right Hanad Side. So, 4cos2 (4x) - 3=0 is true.
Answer:
Answer: a5 = 2500
Step-by-step explanation:
For a geometric sequence:
First term = a0
Second term = a1 = a0*r
Third term = a2 = a0*r^2
Fourth term = a3 = a0*r^3
....
nth term = a(n-1) = a0*r^(n-1)
Given: a1 = 4 = a0*r
Also: r = 5
So, a0*5 = 4 => a0 = (4/5)
a5 = a(6-1) = Sixth term = a0*r^5 = (4/5)*5^5 = 2500
Hope this helps
correct me if im wrong☺
Answer:
After 2 months
Step-by-step explanation:
Isabelle has $1520 in her bank account and she makes automatic $760 monthly payments on a home loan.
If she stops making deposits to that account, then a monthly $760 will be deducted from her account.
After 1 month the balance in her account will become $[ 1520 - 760 ] = $760 and then after 2 months the balance will become $[ 760 - 760 ] = $0
Therefore, after 2 months her account will have zero balance. (Answer)
