Answer:
A. 2
Step-by-step explanation:
When you don't know if a number like 256 is a power of anything, it can work reasonably well to start by simply dividing by the factors you know.
256/2 = 128128/2 = 6464/2 = 3232/2 = 1616 = 2^4, so 256 = 2^4 · 2 · 2 · 2 · 2 = 2^8The 8th root of 2^8 is 2, choice A.

Find the composition of the two functions and show your process:
f(g(x))
Answers
Answer:
x²-6x+9
Step-by-step explanation:
f(x) = x²
g(x) = x-3
f(g(x)) = (x-3)²
=(x-3) (x-3)
= x²-3x-3x+9
= x²-6x+9
Answer:
[tex]f(x) = {x}^{2} \\ g(x) = x - 3 \\ f(g(x) = f(x - 3) = {(x - 3)}^{2} \\ = {x}^{2} - 2 \times x \times 3 + {3}^{2} \\ = {x}^{2} - 6x + 9 \\ thank \: you[/tex]

Law of Exponent
[tex] \displaystyle \large{ {a}^{ - n} = \frac{1}{ {a}^{n} } }[/tex]
Compare the terms.
[tex] \displaystyle \large{ {a}^{ - n} = {( - 2)}^{ - 3} }[/tex]
Therefore, a = -2 and n = 3. From the law of exponent above, we receive:
[tex] \displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{ {( - 2)}^{ 3} } }[/tex]
Exponent Def. (For cubic)
[tex] \displaystyle \large{ {a}^{3} = a \times a \times a }[/tex]
Factor (-2)^3 out.
[tex] \displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{( - 2) \times ( - 2) \times ( - 2)}}[/tex]
(-2) • (-2) = 4 | Negative × Negative = Positive.
[tex] \displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{4 \times ( - 2)}}[/tex]
4 • (-2) = -8 | Negative Multiply Positive = Negative.
[tex] \displaystyle \large{ {( - 2)}^{ - 3} = \frac{1}{ - 8}}[/tex]
If either denominator or numerator is in negative, it is the best to write in the middle or between numerator and denominators.
Hence,
[tex] \displaystyle \large \boxed{ {( - 2)}^{ - 3} = - \frac{1}{ 8}}[/tex]
The answer is - 1 / 8

Answer:
P = 50x + 11
A = ((12x +3 ) × (14x +13)) + ( 1/2 (6x-4)^2)
Step-by-step explanation:
P =( the triangle - the shared side) +( the rectangular P - the shared side with the triangle )
P =2(6x - 4) + (14x +13) + 2 (12x +3)
P = 12x -8 + 14 x + 13 +24x +6
P = 50x + 11
Area = Triangle area + Rectangular area
T area = 1/2 base × hight

Rectangular Area = hight × length

Answer:
Step-by-step explanation:
if you need an answer I would be 112 given the information in the question,
but there seems to be something wrong (probably my interpretation) ..
here is the logic (and why there is an issue) ....
Assuming that every "movement" is "5 forward, then 3 back"
we can assume that every movement takes 8 steps ...
given this one would assume that the total steps has to be a multiple of 8 (but it is not)
460/8 is 57.5 ....
let us assume that came out even... every movement has five forward and three back a net result of 2 forward... if the is repeated 57.5 time the result would be 112 steps forward
it is the 57.5 that does not seem correct

Answer:
8
Step-by-step explanation:
The amplitude is the coefficient of the sine function: 8.
Answer:
8
Step-by-step explanation:
Amplitude is the onehalf of highest value minus the lowest value
since sine function has maximum 1 and minimum -1, then the highest value of f(x) is 8(1) - 3 = 5 and the minimum value is 8(-1)-3 = -11.
Therefore the amplitude is (1/2) ( 5 +11) = 8.

264x³-66x
Step-by-step explanation:
The order of operations requires this be evaluated as ...
11x(96x÷4x -6) . . . . given
11x(24x·x -6) . . . . . . division inside parentheses
11x(24x² -6) . . . . . . multiplication inside parentheses
264x³ -66x . . . . . multiply by outside factor (use the distributive property)
_____
Additional comment
The appearance of the expression in parentheses may induce you to evaluate it as (96x)÷(4x) = 24. The order of operations requires that you do the division before the multiplication, left to right, so this must be evaluated as ...
((96x)÷4)x = 24x²
You need to be very careful with division and with exponents to make sure to follow the Order of Operations exactly. If you have an appropriate calculator, it will do that automatically. For example, if you tell your calculator ...
(for x=2) 11×2×(96×2÷4×2-6)
it should give you the result 1980, not 396.
Answer:
= 198x
Step-by-step explanation:
11x × { 96x ÷ 4x -6}
11x × { 24x -6}
264x - 66x
= 198x
