A. parallelogram
B. I believe it'd be around (11.2,7.5)
C. √(10-5)^2+(9-4)^2 = 21, so yes they bisect
Step-by-step explanation:
problem → 2^x = 4, solve for x
⇒2^x=4
⇒2^x=2^2
⇒x=2
So what you should do is
15% off, then add tax or
2075 times 0.85 times 1.185=2090.04 about
you can't just add and subtract percents because they are percents of different things
what he did was
he found 15% of 2075 and 18.5% of 2075 then found the difference and added to 2075 to find his total
what he should have done is
found the discounted price (15% off) then found the tax on that
first way
2075 times 0.15=311.25
2075-311.25=1763.75
1763.75 times 0.185=326.29375
1763.75-326.29375=2090.04
2nd way (easy, if you understand commutative property and stuff)
100-15=85
1+0.185=1.185
2075*0.85*1.185=2090.04
answer should be $2090.04
19.20 divided by 7.5
= 2.56
2.56 is your answer.
A=Annual amount=2000
i=annual interest=0.0205
n=number of years=3
Present value
=A((1+i)^n-1)/(i(1+i)^n)
=2000(1.0205^3-1)/(.0205(1.0205^3))
=5762.15
