Answer: ∞

Step-by-step explanation: First, find the indefinite integral F (x), and then evaluate F (∞)–F(– ∞).

Answer:

17

Step-by-step explanation:

If you are trying to solve the equation "y-12=c" for y, you would begin by adding 12 to both sides of the equation to obtain "y=c+12". This means that y is equal to the value of c plus 12.

For example, if you were given the equation "y-12=5", you would have "y=5+12" or "y=17".

The expression for the total amount of sales the store makes will be:25s + 28.8p

Expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both.

From the information, the shoe store stocks x pair of sneakers and y pairs of sandals. During a promotion, a pair of sneakers is priced at $50 and a pair of sandals at $36. The shop manages to sell half the sneakers and 80% of the sandal.

Let sneakers = s

Let sandals = p

An expression for the total amount of sales the store makes will be: 1/2(50s) + 0.8(36p).

= 25s + 28.8p

The answer choice which correctly draws a comparison between the end behaviors of the functions is; Choice C; They have the same end behavior as x approaches -∞ and same end behavior as x approaches ∞.

As given in the task content; the graph of the exponential function passes through (-4, 9), (0, 1), (1, 0), and (5, -2).

It therefore follows that as; x reduces (approaches -∞), the y value increases.

And, as x -increases (approaches +∞), the y-value decreases.

For the table, the values can be written as coordinates as follows; (-1,2), (0,4), (1,6), (2, 0), (3,-2).

Consequently, as x reduces (approaches -∞), the y- values decrease.

And, as x increases (approaches +∞), the y-values decrease.

Ultimately, the two functions in discuss can be concluded to have; Choice C.

Answer:

Do you want to be extremely boring?

Since the value is 2 at both 0 and 1, why not make it so the value is 2 everywhere else?

\(f(x) = 2\) is a valid solution.

Want something more fun? Why not a parabola? \(f(x)= ax^2+bx+c\).

At this point you have three parameters to play with, and from the fact that \(f(0)=2\) we can already fix one of them, in particular \(c=2\). At this point I would recommend picking an easy value for one of the two, let's say \(a= 1\) (or even \(a=-1\), it will just flip everything upside down) and find out b accordingly:\(f(1)=2 \rightarrow 1^2+b+2=2 \rightarrow b=-1\)

Our function becomes

\(f(x) = x^2-x+2\)

Notice that it works even by switching sign in the first two terms: \(f(x) = -x^2+x+2\)

Want something even more creative? Try playing with a cosine tweaking it's amplitude and frequency so that it's period goes to 1 and it's amplitude gets to 2: \(f(x) = A cos (kx)\)

Since cosine is bound between -1 and 1, in order to reach the maximum at 2 we need \(A= 2\), and at that point the first condition is guaranteed; using the second to find k we get \(2= 2 cos (k1) = cos k = 1 \rightarrow k = 2\pi\)

\(f(x) = 2cos(2\pi x)\)

Or how about a sine wave that oscillates around 2? with a similar reasoning you get

\(f(x)= 2+sin(2\pi x)\)

Sky is the limit.

Step-by-step explanation:

you would have to split the shape into two different shapes.

9x12=108

then you would add both areas to get 276 which is the total area for this shape.

a. The secant slope through (-2,4) and (0,0) is -2.

b. The secant slope through (-1.5,2.25) and (-0.5,0.25) is -2.

The estimated slope of the tangent line to f(x) = x^2 at x = -1 is approximately -2.

To estimate the slope of the tangent line to the function f(x) = x^2 at x = -1, we can find the slopes of the secant lines through different pairs of points.

a. (-2,4) and (0,0):

The coordinates of the two points are (-2, 4) and (0, 0). We can calculate the slope of the secant line passing through these points using the formula:

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

Plugging in the values, we get:

msec = (0 - 4) / (0 - (-2))

= -4 / 2

= -2

So, the slope of the secant line passing through (-2, 4) and (0, 0) is -2.

b. (-1.5, 2.25) and (-0.5, 0.25):

The coordinates of the two points are (-1.5, 2.25) and (-0.5, 0.25). Using the slope formula, we can calculate the slope of the secant line passing through these points:

msec = (0.25 - 2.25) / (-0.5 - (-1.5))

= (-2) / (1)

= -2

So, the slope of the secant line passing through (-1.5, 2.25) and (-0.5, 0.25) is -2.

By finding the slopes of the secant lines, we have estimated the rate of change of the function f(x) = x^2 at x = -1. The slope of the tangent line at this point will be very close to these secant slopes, particularly as the two points used to calculate the secant lines get closer together.

The values of x and y that makes the figure a parallelogram are x = 17 and y = 26

A parallelogram is a four-sided geometric shape that has opposite sides that are parallel to each other.

The opposite sides of a parallelogram have the same length, and the opposite angles are also equal. The opposite sides of a parallelogram are also known as the bases, and the other two sides are known as the legs.

Since the opposite sides of a parallelogram are equal in length, we can say:

3x + 6 = 4 - x

3x + x = 4 - 6

4x = -2

x = -2/4

x = -1/2 = -0.5

y + 2 = 2y - 3

2 + 3 = 2y - y

5 = y

y = 5

Likewise, the opposite angles of a parallelogram are equal, so we can say:

(4x - 12)° = (3x + 5)°

4x - 12 = 3x + 5

4x - 3x = 5 + 12

x = 17

(3y + 46)° = (5y - 6)°

3y + 46 = 5y - 6

46 + 6 = 5y - 3y

52 = 2y

2y = 52

y = 52/2

y = 26

Thus, x = 17 and y = 26 makes the figure a parallelogram

Answer:

\(area = (7 \times 1) + (5 \times 1) + (8 \times 1) \\ = 7 + 5 + 8 \\ = 20 \: {m}^{2} \)

Part(a),

The exponential function that models the total spent on food and drinks as a function of the number of years since 1990 is:

\(T(x) = 641 \times ((\dfrac{1016}{641})^{(\frac{1}{13}))^x\)

Part(b),

The predicted amount spent in 2000 is 964 billion dollars (rounded to the nearest integer).

Part(c),

The predicted total sales of food and drink in 2018 is 1756 billion dollars

Part(d),

If the exponential trend continues, the total sales will reach 2 trillion dollars approximately 32.72 years after 1990, which is around the year 2022.

(a) To model the total spent on food and drinks as an exponential function of the number of years since 1990, we can use the general form of an exponential function:

\(T = a \times b^t\)

where T is the total spent in billions of dollars, t is the number of years since 1990, a is the initial amount spent in 1990, and b is the growth factor or base of the exponential function.

Using the given information, we can set up two equations:

T(0) = 641 (total spent in 1990)

T(13) = 1016 (total spent in 2003, which is 13 years after 1990)

Substituting these values into the exponential function, we get:

\(641 = a \timrd b^0\) => a = 641

\(1016 = a b^{13\) => \(b = (\dfrac{1016}{641})^{\frac{1}{13}\)

Therefore, the exponential function that models the total spent on food and drinks as a function of the number of years since 1990 is:

\(T(x) = 641 \times ((\dfrac{1016}{641})^{(\frac{1}{13})^x\)

(b) To predict the amount spent in 2000, we need to substitute t = 10 (since 2000 is 10 years after 1990) into the exponential function:

\(T(10) = 641 \times ((\dfrac{1016}{641})^{(\frac{1}{13}))^{10\) ≈ 964

Therefore, the predicted amount spent in 2000 is 964 billion dollars (rounded to the nearest integer).

(c) To predict the total sales of food and drink in 2018, we need to substitute t = 28 (since 2018 is 28 years after 1990) into the exponential function:

\(T(28) = 641 \times ((\dfrac{1016}{641})^{(\frac{1}{13}))^{28\) ≈ 1756

Therefore, the predicted total sales of food and drink in 2018 is 1756 billion dollars (rounded to the nearest integer).

(d) To estimate when the total sales will reach 2 trillion dollars, we need to solve for t in the exponential function when T(t) = 2000 (since 2 trillion dollars is equivalent to 2000 billion dollars):

\(2000 = 641 \times ((\dfrac{1016}{641})^{(\frac{1}{13}))^t\)

\(ln(\dfrac{2000}{641}) = t \times ln((\dfrac{1016}{641})^{(\frac{1}{13})\)

\(t = \dfrac{ln(\dfrac{2000}{641})} { ln((\dfrac{1016}{641})^{(\frac{1}{13})) }}\)

t = 32.72

Therefore, if the exponential trend continues, the total sales will reach 2 trillion dollars approximately 32.72 years after 1990, which is around the year 2022.
