Step-by-step explanation:
27^x = 9^(x - 4)
3^3x = 3^2(x - 4)
3x = 2(x - 4)
3x = 2x - 8
3x - 2x = -8
x = -8
Answer:
=
−
282.54
Step-by-step explanation:
I'm not sure if that's x=4 or x= -4, but I'll solve both.
x=4:
11(4) - 4 = 44 - 4 = 40
x = -4:
11(-4) - 4 = -44 -4 = -48
Have an awesome day! :)
We have already seen how to approximate a function using its tangent line. This was the key idea in Euler’s
method. If we know the function value at some point (say f (a)) and the value of the derivative at the same
point (f
(a)) we can use these to find the tangent line, and then use the tangent line to approximate f (x)
for other points x. Of course, this approximation will only be good when x is relatively near a. The tangent
line approximation of f (x) for x near a is called the first degree Taylor Polynomial of f (x) and is:
f (x) ≈ f (a) + f
(a)(x − a)
$3.90
You have to take $1.16 and multiply it by 2 so that you get the price for 4 pounds then divide 1.16 by 2. Then you have to add together the totals and you'll get the price for 5 pounds.
Or
You could take $1.16 divide it by 2 to get the unit price then multiply (or add it together 5 times) it by 5 to get a total of $3.90
