Emma's profit from selling the stock is $743.44.

To find out Emma's profit from selling the stock, we need to calculate the total cost of purchasing the stock and the total revenue from selling the stock. Then we can subtract the total cost from the total revenue to get the profit.

Total cost of purchasing the stock:

Emma bought 300 shares of the stock for $39.22 per share plus a 1 percent commission.

Commission = 1% of (300 x $39.22) = $117.66

Total cost = (300 x $39.22) + $117.66 = $11,871.66

Total revenue from selling the stock:

Emma sold 300 shares of the stock for $46.54 per share plus a commission of $49.95 plus $24 per share.

Commission = $49.95 + (300 x $24) = $7,449.95

Total revenue = (300 x $46.54) - $7,449.95 = $12,665.05

Profit:

Profit = Total revenue - Total cost - Commission

Profit = $12,665.05 - $11,871.66 - $49.95 = $743.44

Therefore, Emma's profit from selling the stock is $743.44.

Emma received $6,512.05 after selling the 300 shares of stock in the fast food company.

What is an algebraic expression?

An algebraic expression is a mathematical phrase that contains variables, constants, and mathematical operations. It may also include exponents and/or roots. Algebraic expressions are used to represent quantities and relationships between quantities in mathematical situations, often in the context of problem-solving.

To calculate the total amount Emma paid for the stock, we first need to calculate the commission she paid when she purchased it:

1% commission = 0.01 * 39.22 = 0.3922

Total cost per share = 39.22 + 0.3922 = 39.6122

So, Emma paid $39.6122 per share when she bought the stock.

To calculate the total amount she received for selling the 300 shares, we need to first calculate the commission she paid for selling it:

Commission per share = 24

Total commission = 300 * 24 + 49.95 = 7,449.95

The total amount she received for selling the shares is:

300 * 46.54 = 13,962

Therefore, the total amount of money Emma received after selling the shares and paying the commission is:

13,962 - 7,449.95 = 6,512.05

Therefore, emma received $6,512.05 after selling the 300 shares of stock in the fast food company.

Answer: 9g+10

Step-by-step explanation:

Simple addition 6+3=9

Since 10 doesnt have a variable you just add it to the end of the equation, make sure to keep the sign = 9g-10

So the y-intercept is 4 the equation of the line in slope-intercept form is:

y = 2x + 4

When the line to be examined's slope is known, and the provided point also serves as the y intercept, the slope intercept formula, y = mx + b, is utilised (0, b).

y = mx + b

m = (y2 - y1) / (x2 - x1)

Using the points (-4, -4) and (1, 6), we can find the slope of the line passing through them:

m = (6 - (-4)) / (1 - (-4)) = 10 / 5 = 2

So the slope of the line is 2.  Let's use the point (1, 6):

y = mx + b

6 = 2(1) + b (substitute m = 2, x = 1)

6 = 2 + b

b = 6 - 2 = 4

So the y-intercept is 4 the equation of the line in slope-intercept form is:

y = 2x + 4

Step-by-step explanation:

f(0):

f(0) = (0^2 - 9) / (0 + 5)

= -9/5

f(-1):

f(-1) = ((-1)^2 - 9) / (-1 + 5)

= (-8) / 4

= -2

f(1/k):

f(1/k) = ((1/k)^2 - 9) / (1/k + 5)

= (1/k^2 - 9) / (1/k) + 5

= (1 - 9k^2) / (k^2 + 5k)

Therefore, f(0) = -9/5, f(-1) = -2, and f(1/k) = (1 - 9k^2) / (k^2 + 5k).

Answer:

Step-by-step explanation:

To find the values of f(x) at the given points, we substitute the values of x into the expression for f(x) and simplify:

f(x) = (x^2 - 9)/(x + 5)

a) To find f(0), we substitute 0 for x:

f(0) = (0^2 - 9)/(0 + 5) = -9/5

Therefore, f(0) = -1.8.

b) To find f(-1), we substitute -1 for x:

f(-1) = (-1^2 - 9)/(-1 + 5) = (-10)/4

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor of 2:

f(-1) = -5/2

Therefore, f(-1) = -2.5.

c) To find f(1/k), we substitute 1/k for x:

f(1/k) = ((1/k)^2 - 9)/(1/k + 5)

We can simplify the numerator by multiplying out the square:

f(1/k) = (1/k^2 - 9)/(1/k + 5)

We can simplify the denominator by multiplying by k/k:

f(1/k) = (1 - 9k^2)/(1 + 5k)

Therefore, f(1/k) = (1 - 9k^2)/(1 + 5k).

The total distance driven during the 4-hour trip is approximately 294.05 miles

An element of a number or any number of equal pieces is represented by a fraction. There is a fraction with an upper value (numerator) and a lower value (denominator) (lower value).

We must sum up the distances for each hour of the 4-hour journey to get the overall mileage.

1 hour's worth of driving covered 55.25 miles.

64 3/4 miles were covered in Hour 2 of driving.

52 3/10 miles were covered in Hour 3 of driving.

67.89 miles were covered in Hour 4 of driving.

We must transform the mixed number from Hour 2 into an improper fraction in order to sum these distances:

Driving distance in hour two: 64 3/4 = (4 x 64 + 3) / 4 = 259 / 4

We can now calculate the distances:

55.25 + 259/4 + 52.3 + 67.89

We need to find a common denominator so that we can add these numbers:

55.25 = 221/4

259/4 = 259/4

52.3 = 523/10

67.89 = 6789/100

We may now multiply the fractions:

221/4 + 259/4 + 523/10 + 6789/100 = 5881/20

5881/20 = 294 1/20 is the result of converting this improper fraction to a mixed number.

As a result, the 4-hour trip's total mileage came to about 294.05 miles.

P(-2.33 ≤ z ≤ 2.33) = 0.98 for a standard normal random variable Z.

We are aware that the area under the curve between - and - is equal to 1 for a standard normal random variable Z.

The task of finding a number for z0 such that P(-z0 z z0) = 0.98 is given to us.

We can divide the area of 0.98 evenly between the two tails of the distribution since the normal distribution is symmetric around the mean.

(1 - 0.98 / 2) = 0.01 would be the area in each tail.

We can determine the z-score that corresponds to the area of 0.01 by using a calculator or a conventional normal distribution table. An area of 0.01 equates to a z-score of roughly -2.33.

Thus, z0 would have the value:

z0 = -(-2.33) = 2.33

The statement missing in the proof is option D. m ∠ ⁢ 3 + m ∠ ⁢ 5 = 180 ∘.

A triangle is classified as a geometric shape with three sides and three angles. It is one of the basic shapes in geometry, and is typically characterized by its three interior angles, which must add up to 180 degrees. The most common types are the equilateral triangle (all sides equal), the isosceles triangle (two sides equal), and the scalene triangle (no equal sides).

A proof involves logical deduction of the statements in order to arrive at a conclusion. In this case, the conclusion is that the angles 3, 5, and 7 are all congruent. To do this, the proof must show that the angles add up to 180 degrees, which is the sum of the angles in a triangle. Option D, m ∠ ⁢ 3 + m ∠ ⁢ 5 = 180 ∘, is the statement that must be included in the proof to show that the angles are congruent. Without this statement, it is impossible to prove that the three angles are congruent. Therefore, Option D is the missing statement in the proof.

The function P(t) = 3.5(0.91)^t is an exponential decay and the percentage rate of change is 9%.

option B.

The function P(t) = 3.5(0.91)^t is an exponential decay function because the base, 0.91, is between 0 and 1.

To find the percentage rate of change, we need to find the value of r in the exponential function;

P(t) = P(0) (1 + r)^t or

P(t) = P(0) e^(rt)

where;

In this case, the initial value is 3.5, and the function is P(t) = 3.5 (0.91)^t. Comparing this to the form P(t) = P(0) e^(rt),

we see that P(0) = 3.5 and r = ln(0.91) ≈ -0.094.

The statement that cannot be true is "length RW is a midsegment of the triangle".

option D.

The midsegment of a triangle is a line segment that connects the midpoints of two sides of a triangle. More specifically, if a triangle has sides of lengths a, b, and c, then the midsegment connects the midpoints of the two sides of length a and is parallel to the side of length c.

The length of the midsegment is half the length of the third side (c/2).

In other words, if a triangle has sides AB, BC, and AC, then the midsegment connects the midpoint of AB (denoted as M) to the midpoint of BC (denoted as N) and is parallel to AC. The length of the midsegment MN is equal to half the length of AC (MN = 1/2 * AC).

Answer:

Step-by-step explanation:

Let's simplify - 4 - (-5):-

[tex]\tt -4 - (-5)[/tex]

[tex]\tt -4+5[/tex]

[tex]\tt 1[/tex]

Now, let's see which expression has the same value:-

F. -4 + (-5)

[tex]\tt -4 + (-5)[/tex]

[tex]\tt -4-5[/tex]

[tex]\boxed{\tt -9}[/tex]

________________

G. -4 +5

[tex]\tt -4 +5[/tex]

[tex]\boxed{\tt 1}[/tex]

_________________

H. -5 + (-4)

[tex]\tt -5 + (-4)[/tex]

[tex]\tt -5-4[/tex]

[tex]\boxed{\tt -9}[/tex]

_________________

J. -5-(-4)

[tex]\tt -5-(-4)[/tex]

[tex]\tt -5+4[/tex]

[tex]\boxed{-1}[/tex]

Therefore, we can say that G. -4 +5 has a similar value as

-4 - (-5).
