Answer:
21/40
Step-by-step explanation:
Answer:
131 cm
Step-by-step explanation:
formula for surface area of pyramid is
S = (1/3)Bh
but the base ia a square, so B = 
S = (1/3)
the pic shows h = 8
but we don't know x
do SohCahToa
sin60 = x/8
x = 8sin60
x = 6.92820323 or 7
plug in numbers
S = (1/3)
8
S = 392/3
S = 130.6666667 or 131 cm
Answer:
1. 120
2. 2600
Step-by-step explanation:
6% of 2000 = 120
2000+120(5)
2000+600
=2600
Please note that your x^3/4 is ambiguous. Did you mean (x^3) divided by 4
or did you mean x to the power (3/4)? I will assume you meant the first, not the second. Please use the "^" symbol to denote exponentiation.
If we have a function f(x) and its derivative f'(x), and a particular x value (c) at which to begin, then the linearization of the function f(x) is
f(x) approx. equal to [f '(c)]x + f(c)].
Here a = c = 81.
Thus, the linearization of the given function at a = c = 81 is
f(x) (approx. equal to) 3(81^2)/4 + [81^3]/4
Note that f '(c) is the slope of the line and is equal to (3/4)(81^2), and f(c) is the function value at x=c, or (81^3)/4.
What is the linearization of f(x) = (x^3)/4, if c = a = 81?
It will be f(x) (approx. equal to)
