Answer:
Step-by-step explanation:
Distance covered by the train in crossing the pole = 100 m.
- Hence, the speed of the train is 72 km/h
Given: f(x) = x² + 7
Let y = x² + 7
x = y² + 7 (since the inverse is reflected about the y = x line, the coordinates are interchangeable)
y² = x - 7
y = √(x - 7)
Thus, the inverse function f^(-1)x = √(x - 7)
Answer:
why do fifth grade teachers want hotdogs
Step-by-step explanation:
???????????????
Listed price = $1.4 million
Down payment = 20% of $1.4 million = 0.2 x 1,400,000 = 280,000
Amount left to pay = $1.4 million - 280,000 = $1,120,000
Present value of an annuity is given by PV = P(1 - (1 + r/t)^-nt) / r
where: PV = $1,120,000
r = 5% = 0.05
t = 12
n = 30 years.
1,120,000 = P(1 - (1 + 0.05/12)^-(12 x 30)) / 0.05
1,120,000 x 0.05 = P(1 - (1 + 1/240)^-360)
56,000 = P(1 - 0.2238)
P = 56,000 / 0.7761 = 72,148.83
Therefore, the monthly payment is $72,148.83
37.5% is what I think the correct answer is sorry if its wrong
