The stock was worth 40000 dollars in 1998.

Stocks, also known as equities, are securities that represent ownership in a corporation.  The value of your stock holdings is directly tied to the performance of the company and its financial health.

There are two main types of stocks: common stocks and preferred stocks. Common stocks typically offer voting rights, while preferred stocks generally do not. Preferred stocks often offer a fixed dividend, while common stock dividends can vary.

Stocks are bought and sold on stock exchanges, such as the New York Stock Exchange (NYSE) and the NASDAQ.

The value of the stock quintupled every 9 years, which means it increased by a factor of 5 every 9 years. To find the value of the stock in 1998, we need to divide the value in 2016 by 5 raised to the power of the number of 9-year intervals that have passed.

Let's call the value of the stock in 2016 x. Then:

x = million dollars = 1000000

The number of 9-year intervals that have passed is (2016 - 1998) / 9 = 18 / 9 = 2

So, the value of the stock in 1998 is x / (5^2) = 1000000 / (5^2) = 1000000 / 25 = 40000.

Therefore, the stock was worth 40000 dollars in 1998.

Answer:

During winter in the Arctic, a lake gets frozen solid with ice. But as spring comes, the ice starts to melt. This happens because the temperature gets warmer and there's more sunlight. It's a natural process that happens every year and shows the change of seasons.

Step-by-step explanation:

The maximum height of the ball is 200 feet.

An expression can be used to solve for a single unknown value, for example, the equation 2x + 3 = 7 can be solved for x by subtracting 3 from both sides, giving us 2x = 4 and then dividing both sides by 2, giving us x = 2. In this example, x = 2 is the solution to the equation.

To find the time to the highest point, we need to find the time when the velocity of the ball is equal to zero. The velocity of the ball can be found by taking the derivative of the height equation with respect to time.

The derivative of h with respect to t is:

dh/dt = 32t + 64

Setting the derivative equal to zero and solving for t, we get:

0 = 32t + 64

-64 = 32t

t = -2

So, the time to the highest point is -2 seconds. However, since time cannot be negative in this context, we can say that it takes 2 seconds for the ball to reach its highest point.

To find the maximum height, we can substitute the time of 2 seconds back into the original height equation:

h = 16(2)^2 + 64(2) + 8

h = 64 + 128 + 8

h = 200

So, the maximum height of the ball is 200 feet.

Answer:

b = 33 millimeters.

Step-by-step explanation:

In a right triangle, the Pythagorean theorem states that the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the legs (a and b). So, using a=56 and c=65, we can find b by solving the equation: 56^2 + b^2 = 65^2. This gives b = sqrt(1089) = 33 millimeters :)

If Mo and Beth split £48 in the ratio 3.5, Beth gets £10.67.

Let's call the amount that Beth gets "x". Then, the amount that Mo gets is 3.5x.

We know that the total amount they split is £48, so we can set up the following equation:

x + 3.5x = £48

Next, we'll simplify the left side of the equation by combining like terms:

4.5x = £48

Finally, we'll solve for x by dividing both sides of the equation by 4.5:

x = £48 / 4.5 = £10.67

So Beth gets £10.67.

The most correct answer is D ( 3,-2) . Because in the 2 equations above when you enter the value x= 3 in equation I and II, it produces y=-2.

In the question above, there are two equations.

y=-(½)x - ½ (eq I)

y=-(⅔)x (eq II)

To find which x and y values satisfy these two equations in options A,B,C,D, we have to substitute one by one to prove:

A.(-2, 3)

we substitute the value x=-2 into equation I

y=-(½)x - ½

y= -(½) (-2) -½

y=1-½

y= ½ ( This means that option A is not valid, because it should give y a value of 3)

B.(-1,0)

we substitute the value x=-1 into equation I

y=-(½)x - ½

y= -(½) (-1) -½

y= ½ - ½

y= 0

Then, we try to substitute the value x=-1 into equation II

y=-(⅔)x

y= -(⅔) (-1)

y= ⅔ ( This means option B is not valid, because it should result in y being 0)

C.(1, 2)

we substitute the value x=1 into equation I

y=-(½)x - ½

y= -(½) (1) -½

y= -½ - ½

y= -1 ( This means option C is not valid, because it should result in y being 2)

D. (3,-2)

we substitute the value x=3 into equation I

y=-(½)x - ½

y= -(½) (3) -½

y= -3/2- ½

y=-4/2

y= -2

Then, we try to substitute the value x=3 into equation II

y=-(⅔)x

y= -(⅔) (3)

Given that savings account earns 4% annual simple interest.

The principal is $1700.

We need to find the balance after 6 years.

The formula for simple interest I=Prt

I = interest

P = principal ($1700)

Answer:

  (d)  x-axis

Step-by-step explanation:

You want the line of reflection that transforms Z(10, -8) to Z'(10, 8).

The line of reflection is the perpendicular bisector of the segment between a point and its image.

Here, the segment ZZ' is on the vertical line x=10, so the bisector will be a horizontal line whose y-value is the average of the y-values of Z and Z':

  y = (-8 +8)/2 = 0/2 = 0

The line y=0 is the x-axis. The line of reflection is the x-axis.

Rather than go to the trouble of considering perpendicular bisectors, you can simply make use of your knowledge of reflection over the axes:

Answer:

So the inverse of F(x) is F^-1(x) = 1 ± sqrt((x-2)/5).

Step-by-step explanation:

To find the inverse of F(x), we need to follow these steps:

Step 1: Replace F(x) with y:

y = 5x^2 - 10x + 7

Step 2: Solve for x in terms of y:

y = 5x^2 - 10x + 7

y - 7 = 5x^2 - 10x

5x^2 - 10x = y - 7

5(x^2 - 2x) = y - 7

Completing the square:

5(x^2 - 2x + 1) = y - 7 + 5

5(x - 1)^2 = y - 2

x - 1 = ±sqrt((y-2)/5)

x = 1 ± sqrt((y-2)/5)

Step 3: Replace x with F^-1(x):

F^-1(x) = 1 ± sqrt((x-2)/5)

So the inverse of F(x) is F^-1(x) = 1 ± sqrt((x-2)/5).

The average velocity of the object from t = 2 and t = 4 is equal to - 48 feet per second.

In this problem we find the case of an object thrown upward, whose height (h(t)), in feet, as a function of time (t), in seconds, is represented by a quadratic equation. We need to determine the average velocity (u) of the object by means of secant line formula:

u = [h(4) - h(2)] / (4 - 2)

Where:

If we know that h(t) = - 16 · t² + 48 · t + 120, then the average velocity is:

t = 2

h(2) = - 16 · 2² + 48 · 2 + 120

h(2) = 152 ft

t = 4

h(4) = - 16 · 4² + 48 · 4 + 120

h(4) = 56 ft
