this is the answer I got out of my calculator. so your answer is going to be your second choice.

Answer:

Stock A daily average change in price for one share = -$2.16

Stock B daily average change in price for one share = -$1.45

Stock C daily average change in price for one share = -$1.43

Step-by-step explanation:

Since we desire to find the price of each stock per day or its daily average change in price for one share, we divide the price change of one share of stock by the total number of days it took to change.

So for stock A, daily average change = price change/number of days

price change = -$4.32, number of days = 2

daily average change  =  -$4.32/2 =  -$2.16

for stock B, daily average change = price change/number of days

price change = -$5.80, number of days = 4

daily average change  =  -$5.80/4 =  -$1.45

for stock C, daily average change = price change/number of days

price change = -$2.86, number of days = 2

daily average change  =  -$2.86/2 =  -$1.43

Answer:

Stock A = -1.44

Stock B = -1.45

Stock C = -1.43

Step-by-step explanation:

-4.32 ÷ 3 = -1.44

-5.80 ÷ 4 = -1.45

-2.86 ÷ 2 = -1.43

Answer:

50 percent

5,730 years; The graph shows that 50 percent of the carbon-14 atoms have decayed after 5,730 years, so 5,730 is the half-life of carbon-14. 2. 12.5% 3.

Radiocarbon dating involves determining the age of an ancient fossil or specimen by measuring its carbon-14 content. ... Green plants absorb the carbon dioxide, so the population of carbon-14 molecules is continually replenished until the plant dies. Carbon-14 is also passed onto the animals that eat those plants.

Answer:

If instructed to simplify the question, your answer is -5+8x.

Step-by-step explanation:

-18 divided by -6 equals positive 3.

3 + 8x -8 would become -5+8x, because 3 minus 8 is -5. Hope this helps!

Answer:

Step-by-step explanation:

Given the subtraction problem;

2.25-(-0.25)

First we will need to open up the parenthesis by multiplying the signs. product of two negative signs will result in a positive. Hence the equation becomes;

= 2.25+0.25

Convert to fraction;

= 225/100 + 25/100

Find the LCM

= (225+25)/100

= 250/100

= 2.50

Hence the difference of both values on the number line is 2.5

Answer:

77

Step-by-step explanation:

c + 103 = 180

180- 103 = 77

c and b = 77

The composite function f(g(4)) has a value = 182, given f(x) = x² + x, and g(x) = 3x + 1.

What is the combination of functions?

f(g(x)) or (f ∘ g)(x) represents the aggregate of functions f(x) and g(x), wherein g(x) acts first. It is a function that combines more functions to supply some other function. The output of one function inside the parenthesis will become the input of the outer function in composite functions. i.e.,

g(x) is the input of f(x) in f(g(x)).

f(x) is the input of g(x) in g(f(x)).

We are given functions:

f(x) = x² + x

g(x) = 3x + 1

We are asked to discover the value of the composite function f(g(4)).

We first discover the value of g(4) with the aid of using substituting x = 4 in g(x).

∴ g(4) = 3(4) + 1 = 12 + 1 = 13.

Now, we use the value of g(4) = 13, in f(x) to compute the value of f(g(4)).

∴ f(g(4)) = f(13).

To discover f(13), we substitute x = 13 in f(x)

∴ f(13) = 13² + 13 = 169 + 13 = 182.

∴ The composite function f(g(4)) = 182, given f(x) = x² + x, and g(x) = 3x + 1.

Step-by-step explanation:

[tex](-1/3) ^4\\\\\mathrm{Apply\:exponent\:rule}:\\\quad \left(-a\right)^n=a^n,\:\quad \mathrm{if\:}n\mathrm{\:is\:even}\\\\\left(-\frac{1}{3}\right)^4=\left(\frac{1}{3}\right)^4\\\\\mathrm{Apply\:exponent\:rule}:\\\quad \left(\frac{a}{b}\right)^c=\frac{a^c}{b^c}\\\\\left(\frac{1}{3}\right)^4=\frac{1^4}{3^4}\\\\1^4=1\\3^4=81\\\\=\frac{1}{81}[/tex]

The value of [tex]\((-1/3)^4\)[/tex] using property of exponents is [tex]\(\dfrac{1}{81}\)[/tex].

To simplify the expression [tex]\((-1/3)^4\)[/tex], calculate the power of the numerator and the denominator separately.

[tex]\((-1/3)^4 = \left(\dfrac{-1}{3}\right)^4\)[/tex]

Now, let's simplify each part:

[tex]\(\left(\dfrac{-1}{3}\right)^4 = \dfrac{(-1)^4}{3^4}\)[/tex]

Using the exponent property

[tex](\dfrac{a}{b} )^4 = \dfrac{a^4}{b^4}[/tex]

[tex]\(\dfrac{(-1)^4}{3^4} = \dfrac{1}{3^4}\)[/tex]

The denominator [tex]\(3^4\)[/tex] means 3 raised to the power of 4, which equals 81.

[tex]\(\dfrac{1}{3^4} = \dfrac{1}{81}\)[/tex]

Therefore, [tex]\((-1/3)^4\)[/tex]simplifies to  [tex]\(\dfrac{1}{81}\)[/tex].
