Solve the equation 3 . 10^4 = 3,600
quester [9]
The solution is false!
3.1 would become a fraction that will be calculated back into a decimal by the 4th power making it 92.3521=3,600.. so the equality is false because the left hand and the right hand side are different.

Use the given graph of f to state the value of each quantity, if it exists. (If an answer does not exist, enter DNE.)
alex41 [277]

Answer:

Hence the answer is given as follows,

Step-by-step explanation:

Graph of y = f(x) given,

(a) \lim_{x\rightarrow 2^{-}}f(x)=3

(b) \lim_{x\rightarrow 2^{+}}f(x)=1

(c) \lim_{x\rightarrow 2}f(x)= DNE \left \{ \therefore \lim_{x\rightarrow 2^{-}} f(x)\neq  \lim_{x\rightarrow 2^{+}}f(x) \right.

(d) f(2)=3

(e) \lim_{x\rightarrow 4}f(x) = 4

(f) f(4)= DNE.{ Hole in graph}

Hence solved.

If you know that​ R' (20)=50 and​ R''(20)=-4, approximate​ R'(24)
vladimir1956 [14]

Approximate <em>R'</em> by using a linear approximation: for <em>x</em> close enough to 24, you have

<em>R'(x)</em> ≈ <em>L(x)</em> = <em>R' </em>(20) + <em>R''</em> (20) (<em>x</em> - 20)

Then

<em>R'</em> (24) ≈ <em>R'</em> (20) + <em>R''</em> (20) (24 - 20) = -4 + 50 (24 - 20) = 196
