Answer:
105,3≈105
Step-by-step explanation:
sin 72°=19/20
sin 72°=100/x
x=(20*100)/19=105,3
x=BC
x- is hypotenuse
i calculated with calculator
Answer:
Principal = 3500
Time = 8 years
We are given that compound quarterly
So, No. of compounds per year = 2
Rate of interest = 5%
Formula : 
Substitute the values :


Interest = 3863.345 - 3500 = 363.345
Hence the total amount in an investment of $3500 that was compounded quarterly for 8 years at a rate of 5% is $3863.345 and the interest that was made on that account mentioned is $363.345
Some operators are missing.
If the right equations are y = x^2 -6x +8 and 2y + x =4
This is the solution
2y + x = 4
2y = -x +4
y = -x/2 + 2
y = x^2 -6x + 8 = -x/2 + 2
2x^2 - 12x + 16 = -x + 4
2x^2 -11x +12 = 0
Factor
(x-4)(2x-3)=0
x= 4 and x =3/2
y = -x/2 +2
y = -4/2 + 2 = 0
y = - (3/2)/2 + 2 = -3/4 + 2 = 5/4
Answer (4,0) and (3/2, 5/4)
