A stock market analyst observes the following for the price of two stocks that he owns, one of which is increasing at an exponential rate (geometric) and the other is increasing in a linear fashion (arithmetic).
Stock A: Equation: an = 15n + 143, where an is the value of the stock and n is the number of years.
Year Price
1 $158.00
2 $173.00
3 $188.00
4 $203.00
5 $218.00
Stock B: Equation: an = 24(1.1)n − 1, where an is the value of the stock and n is the number of years.
Year Price
1 $24.00

Assuming these stock values continue to increase in the same manner until retirement, which stock option is worth more in 50 years and how much more is this stock worth per share?
HELPPPPPP 100 POINTS PLEASE
Answer:
Use the formulas and find 5th term of both and compare
Stock A
a₅₀ = 15(50) + 143 = $893Stock B
a₅₀ = 24(1.1)⁴⁹ = $2561.25As we see Stock B share has greater value in 50 years and the difference is:
$2561.25 - $893 = $1668.25Find 50th term on both

2561.25-893$1668.25Which ordered pair is a solution of the equation? −7x+3y=2
Answer:
(-2/7,2/3)
Step-by-step explanation:
Let's solve for x.
−7x+3y=2
Step 1: Add -3y to both sides.
−7x+3y+−3y=2+−3y
−7x=−3y+2
Step 2: Divide both sides by -7.
−7x/ −7 = −3y+2/ −7
x= 3/ 7 y+ −2/ 7
Answer:
x= 3/ 7 y+ −2/ 7
Let's solve for y.
−7x+3y=2
Step 1: Add 7x to both sides.
−7x+3y+7x=2+7x
3y=7x+2
Step 2: Divide both sides by 3.
3y/ 3 = 7x+2/ 3
y= 7/ 3 x+ 2/ 3
Answer:
y= 7/ 3 x+ 2/ 3
The surface area of a cylinder with height 2 in. is given by the function f(x) = 2πx2 + 4πx, where x is the radius. If g(x) = 4πx gives the surface area of the side of the cylinder, which combined function gives the total surface area of the two circular bases?
A. f + g
B. g − f
C. f − g
D. f · g
Answer:
C f - g
Step-by-step explanation:
the surface area of a cylinder consists of the two circles (1 at the top, 1 at the bottom) and the surrounding "mantle", the side of the cylinder, that connects the two circles.
there are no other parts.
so, when the function for the whole surface area is
SA(x) = f(x) = 2×pi×x² + 4×pi×x
and the side/ mantle area by itself is
g(x) = 4×pi×x
then when ignoring the side/mantle area part in f(x) the only thing left of the main function f(x) is the surface area of the two circular bases.
therefore, the solution for the function of the surface area of only the two circular bases must be the main function minus the function for the side/mantle area.
=> f - g
Noah wrote the expression 10m - 2c to represent the following scenario.
A bakery sells muffins for $2 each and cakes for $10 each. Write an expression that gives the amount of money, in
dollars, the bakery makes from selling m muffins and c cakes.
Explain why Noah's expression is incorrect. Provide the correct expression that represents the scenario.
Answer:
Noah's expression is wrong because he used the wrong coefficients for the variables, and he used a subtraction sign instead of an addition sign.
The correct expression is 2m + 10c
Step-by-step explanation:
Noah is incorrect because he used the wrong coefficients for both of the variables in the expression.
Since muffins are $2 each, and m is the number of muffins, the amount of money made from the muffins is 2m, not 10m.
Similarly, since cakes are $10 each, and c is the number of cakes, the amount of money made from the cakes is 10c, not 2c.
Noah is also incorrect because he used a subtraction sign instead of an addition sign. The amounts made from the muffins and cakes have to be added together.
Putting all of this together, the correct expression is 2m + 10c.

A fireman leaned a 28 foot ladder against a building. If he placed the ladder 14 feet from the base of the building, what angle is formed between the ladder and the ground
Answer:
The ladder makes an angle of 60 degree from the ground.
Step-by-step explanation:
Length of the ladder, L = 28 feet
distance of ladder, d = 14 feet
Let the angle formed with the ground is A.
According to the trigonometry
[tex]\cos A =\frac{d}{L}[/tex]
[tex]\cos A =\frac{14}{28}[/tex]
cos A = 0.5
A = 60 degree
A dolphin is swimming 20 feet below the surface. It descends another 10 feet before rising 2
feet. How far below the surface is it now? {Show the number sentence.
Answer:
28 feet
Step-by-step explanation:
20 + 10 = 30 - 2 = 28 feet
The dolphin is 20 feet below the surface, goes down another 10 feet, so 30 feet below the surface, and raises two feet, so 28 feet below the surface.

Given: I is the midpoint of ME and SL
which prosulate can be used to prove the triangles congruent?
The solution is, SAS prosulate can be used to prove the triangles congruent.
What is triangle?A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
here, we have,
given that,
I is the midpoint of ME and SL
so, we get,
MI = IE
and, SI = IL
now, we know that,
the opposite angles are equal to each other.
so, we have,
angle MIS = angle LIE
so, for triangle MSI & LIE
We get,
MI = IE
SI = IL
angle MIS = angle LIE
so, we get,
both the triangles congruent by SAS.
Hence, The solution is, SAS prosulate can be used to prove the triangles congruent.

What is the perimeter,in centimeters of triangle QRS?
Answer: 60
Step-by-step explanation:
You have to use Pythagorean Theorem because the other side is not listed of the triangle
Pythagorean Theorem: a² + b² = c²
a² + 20² = 25²
a² + 400 = 625
625-400 = a²
a² = 225
Find the square root of 225 to find the missing length
[tex]\sqrt{225}[/tex] = 15 (this is the missing length for QS
To find the perimeter, add all the sides...

[tex]x=2.05[/tex]
Step-by-step explanation:
To solve this problem, use the trigonometric ratios. The trigonometric ratios for a right triangle (a triangle with a right angle are the following).
[tex]sin(\theta)=\frac{opposite}{hypotenuse}\\\\cos(\theta)=\frac{adjacent}{hypotenuse}\\\\tan(\theta)=\frac{opposite}{adjacent}[/tex]
In this case, one is given the hypotenuse (the side opposite the right angle) and one is asked to find the side adjacent to the given angle. Therefore, it would make the most sense to use the trigonometric ratio of cosine ([tex]cos[/tex]).
[tex]cos(\theta)=\frac{adjacent}{hypotenuse}[/tex]

Why is the average approaching 3.5?
There are no remaining rolls, and the average approaching 3.5 is simply the current average of 3.51.
What is a mean?It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
To find the average approaching 3.5, we need to use the concept of the mean or expected value.
The expected value of a random variable is the long-run average value that we would expect to get if we repeat an experiment many times.
In this case, we can consider each roll of a die as an experiment, and the value of the die as the random variable.
Assuming that the die is fair and has six equally likely outcomes, each with a value between 1 and 6, the expected value of the die is:
E(X) = (1 + 2 + 3 + 4 + 5 + 6)/6 = 3.5
Therefore, if we roll the die many times, we would expect the long-run average value to be 3.5.
Now, if we have rolled the die 3200 times and the average so far is 3.51, we can calculate the sum of all the values rolled so far as:
Sum = (Average so far) x (Number of rolls) = 3.51 x 3200 = 11232
To find the average approaching 3.5, we need to calculate the average of the remaining rolls. Let's call the number of remaining rolls "n". Then we have:
Average approaching 3.5 = (Sum of remaining rolls) / n
We know that the total number of rolls is 3200, so the number of remaining rolls is:
n = 3200 - (number of rolls already rolled)
n = 3200 - 3200 = 0
Therefore,
There are no remaining rolls, and the average approaching 3.5 is simply the current average of 3.51.

Eight friends want to play enough games of chess to be sure everyone plays everyone else. How many games will they have to play?
The number of games, the friends have to play is an illustration of combination.
They have to play 28 games to ensure that they all play
Given
[tex]n = 8[/tex] --- number of friends
[tex]r = 2[/tex] --- only two friends can play at a time
For everyone else to play, we will make use of the following combination formula;
[tex]^nC_r = \frac{n!}{(n - r)!r!}[/tex]
So, we have:
[tex]^8C_2 = \frac{8!}{(8 - 2)!2!}[/tex]
[tex]^8C_2 = \frac{8!}{6!2!}[/tex]
Expand
[tex]^8C_2 = \frac{8 \times 7 \times 6!}{6! \times 2 \times 1}[/tex]
[tex]^8C_2 = \frac{8 \times 7}{2 \times 1}[/tex]
[tex]^8C_2 = 4 \times 7[/tex]
