Find the linear approximation of the function g(x) = 3 1 + x at a = 0. g(x) ≈ Correct: Your answer is correct. Use it to approxi

EleoNora [17]

Answer:

$3.296x+3$

2.835

3.330

Step-by-step explanation:

$g(x) = 3^{1+x}$

Let the linear approximation be L(x) at a = 0. This is given by

$L(x) = g(a) + g'(a)(x-a)$

$g'(x)$ is the derivative of $g(x)$ . To find this, we use the form

If $f(x) = a^x$ , then $f'(x) =a^x\ln a$

By doing this and applying chain rule for the power (which is a function of x), we have

$g'(x) = 3^{1+x}\ln 3$

Then

$g'(0) = 3^{1+0}\ln 3 = 3.296$

Also $g(0) = 3^{1+0} = 3$

Hence $L(x) = 3+(x-0)\times3.296 = 3.296x + 3$

For $3^{0.95}$ , $1+x = 0.95$ and $x=-0.05$

Using this in $L(x)$ ,

$3^{0.95} = 3.296(-0.05) + 3 = 2.835$

For $3^{1.1}$ , $1+x = 1.1$ and $x=0.1$

Using this in $L(x)$ ,

$3^{1.1} = 3.296(0.1) + 3 = 3.330$

Drag steps of the solution into order to solve for x in the equation 8(x+7)=104

Nadusha1986 [10]

Hello!

The first step to solving this equation would be to distribute the 8 to x+7 to simplify the equation:
(8*x)+(8*7)=104
8x+56=104

The second step would be to then subtract 56 from both sides to isolate 8x:
8x+56-56=104-56
8x=48

Finally, the last step would be to divide both sides by 8 to solve for x:
8x/8=48/8
x=6

Your final answer would be x=6

Hope this helps, and Happy New Year!

2 burgers and a soda the soda cost 2 dollars since sale tax was added to his meal at the rate of 10% so 20 cents added 19.80 minus 2.20 (I cant think cause im being rushed lol) which equals 17.60 divided by 2 8.80 dollars each
