Remember, the numerator of an exponenent represents the root. As well, a negative exponent means to take the reciprocal of the positive exponent (
.
So, 
is equal to ![\sqrt[3]{64^{-1}}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B64%5E%7B-1%7D%7D)
which is 1/4, because 1/4*1/4*1/4 is 1/64 (1/64 cubed root is 1/4).
For example, ![a^{b/c} = \sqrt[c]{b^{b}}](https://tex.z-dn.net/?f=a%5E%7Bb%2Fc%7D%20%3D%20%5Csqrt%5Bc%5D%7Bb%5E%7Bb%7D%7D)
The answer is c.
The equation of the line thru <span> (14,5) and (19,15) is found as follows:
15-5 5
slope = m = ----------- = ------ = -1
19-14 5
Thus, the slope of any line perpendicular to this first line has the slope
m = -1/1 = -1.
Then, using the point-slope form, y-15 = -1(x-19), or y -15 = -x + 19, or
y= -x + 34 (answer)</span>
Answer:
51.2
Step-by-step explanation:
15x = 120
x = 8
so now we know that 2 sides of the bigger triangle are 24 and 8
now
96 = 5x
x = 19.2
19.2 + 24 + 8
Center A = $395 for the year
Center B = 25 + 12(15) + 52(5) = $465.
Center A is cheaper.
Can you take a picture closer to the table and graph?
