The answer was BFC????????
Answer:
4.04 (idk how you want it rounded)
Step-by-step explanation:
1) Use TOA
the equation should look like: Tan30= x/7
2) multiply each side by 7 and you’re left with 7Tan30= x
3) in your calculator do 7x30Tan equals and you get your answer
A=P (1+r/n)^nt
A= Total amount invested, P=principal amount, r=Interest rate, n=number of time in a year when the interest is earned (for annual, n=1; for semi-annual, n=2, ...), t = time in years
In the current scenario, case 1, n=2; case 2, n=1 and A1=A2, t1=t2
Therefore,
800(1+0.0698/2)^2t = 1000(1+0.0543/1)t
Dividing by 800 on both sides;
(1+0.0349)^2t = 1.25(1+0.02715)^t
(1.0349)^2t = 1.25(1.02715)^t
Taking ln on both sides of the above equation;
2t*ln (1.0349)= ln 1.25 + t*ln (1.02715)
2t*0.0343 = 0.2231+ t*0.0268
0.0686 t = 0.2231+0.0268 t
(0.0686-0.0268)t = 0.2231
0.0418t=0.2231
t=5.337 years
Therefore, after 5.337 years or 5 years and approximately 4 months, their value of investments will be equal.
This value will be,
A=800(1+0.0698/2)^2*5.337 = $1,153.76
Pareallell lines have same slope
y=mx+b, m=slope
y=3x-8 so we need
y=3x+b
find b
so given (4,-5)
we can subsitute the point
(x,y)
(4,-5)
x=4 then y=-5
so
-5=3(4)+b
-5=12+b
-17=b
y=3x-17 is equation
D is answer
Answer:
A) 3 : 5
Step-by-step explanation:
Scale factor = 24/40 = 3/5 = 3 : 5
