The answer is c. You find the price per ounce. 4.29/24 = .178 then 3.49/18= .193 then 6.39/39= .163 and 2.49/14 = .177. The cheapest is c. Hope this helps!!!
Assuming compount interest format

for compounded per 1 year
A=future amount
P=present amount
r=rate in decimal
t=time in years
given
P=270
r=5%=0.05
the equaton is

or

for any year, 2009, is year 0, so if you wanted to input the year then

would be for t=what year it was
A.

b. 2009 to 2020
2020-2009=11 years
t=11

f(11)=461.792
about 462 cranes
A.

B. about 462

Answer:
True
Step-by-step explanation:
<u><em>Explanation</em></u>:-
The equation of the standard hyperbola is

- Hyperbola is symmetric with respective to both the axes, since if (x, y) is a point on the hyperbola, then (-x, y), (-x,-y), (x,-y) are also lie on the parabola.
- The relation of between focus and transverse and conjugate axes c²=a²+b²
- The transverse axis is along x-axis
- The conjugate axis is along y-axis
- The length of transverse axis is 2 a
- The length of conjugate axis is 2 b
- The foci is (±c,0) and the equation of foci is x=±a e)
- The length of Latus rectum is
