What is (-3)^-9 times (-3)^5
otez555 [7]

Answer:

1/80 or 0.01234568

Step-by-step explanation:

Exponentiation: (-3) ^ (-9) = -5.08052634253E-5 = -1/

19683

Exponentiation: (-3) ^ 5 = -243

= -1/

19683

* (-243) = -1 · (-243)/

19683 · 1

= 243/

19683

= 1 · 243/

81 · 243

= 1/

In order for the limit of F(X) to exist at x=a, which of the following must hold true
astra-53 [7]

Answer:

A.

Step-by-step explanation:

Given: limit of f(x) exists at x = a

To choose: the correct option

Solution:

A limit is a value that a function approaches as the input approaches some value.

\lim_{x\rightarrow a}f(x)=L means that as x approaches to value a then f(x) approaches to value L.

A limit of a function f(x) exists at x = a if \lim_{x\rightarrow a^-}f(x)=\lim_{x\rightarrow a^+}f(x)=L

So, option A. is correct.

A post 47m high is supported by wires attached to its top and to a point on level ground, 18m from the foot of the post. Find th
spayn [35]
We need to use the pythagorean theorem

a^2 + b^2 = c^2

where a and b are the legs, and c is the hypotenuse

47^2 + 18^2 = c^2

c = sqrt(2533)

c = 50.33 

The length of the wire is 50.33 meters.
