Answer:

The work done by the constant unit force vector in moving the object 17 units in the positive x-axis direction is equal to the magnitude of the force multiplied by the displacement in the direction of the force. Since the force makes an angle of 30 degrees with the x-axis, the magnitude of the displacement in the direction of the force is equal to the displacement in the x-axis direction multiplied by the cosine of 30 degrees. Therefore, the work done is equal to the magnitude of the force multiplied by 17 multiplied by the cosine of 30 degrees. hope this helped

The function that best models the number of game consoles sold in millions since 2009 is g(x) = (25.5)(0.6)ˣ.

The correct option is B.

An exponential function's curve is created by a pattern of data called exponential growth, which exhibits higher increases over time.

y = a(1+r)ˣ,

where a is the initial population and r is the rate in decimals and sx is the time period.

Given:

The graph shows the number of game consoles sold in millions since 2009.

Let the function is,

g(x) = abˣ.

And graph passes through two points (0, 25.5) and (1, 15.3).

So,

when x = 0 then g(x) = 25.5.

Answer:

Step-by-step explanation:

To find the value of f(g(-2)), we first need to substitute g(-2) for x in the equation for f(x).

g(-2) = (-2) + 7 = 5

So, f(g(-2)) = f(5)

Now we can substitute 5 for x in the equation for f(x) to find the final value:

f(x) = 3x² - 7x + 15

f(5) = 3(5)² - 7(5) + 15

f(5) = 75 - 35 + 15

f(5) = 55

So, f(g(-2)) = 55

Answer:

a= 17

Step-by-step explanation:

Since all sides are equal length, all angles must be equal. Since all of the angles of every triangle sum to 180*, 180/3= 60*. Therefore, (4a-8)*=60*

From there, we can solve for a by adding 8 to both sides:

(4a-8)+8=60+8

4a=68

Then we can divide both sides by 4 to get

(4a)/4= 68/4

a=17

Answer:

a = 17

Step-by-step explanation:

This seems to be an equilateral triangle, so the angle is 60 degrees. 68 - 8 is 60. 4a represents 4 × a, and we know 4 × a has to be 68. 68 / 4 is 17, meaning a = 17.

What is graph ?

In mathematics, a graph is a collection of points, called vertices, and lines, called edges, that connect the vertices. Graphs are used to represent networks of communication, data organization, computational devices, the flow of computation, and more. Graphs are one of the most fundamental concepts in mathematics, and they are used to model many real-world problems and situations.

The transformation from the first equation to the second one can be found by finding a, h and k for each equation.

y = a / x-h   +   k

Find  a, h and k for

g(x)= 1/x

a = 1

h=0

k = 0

The horizontal shift depends on the value of h and The horizontal shift is described as :

f(x) = f(x+h)  The graph is shifted to the left h units

f(x) = f(x-h) The graph is shifted to the right h units.

Horizontal shift depends on the value of k and The horizontal shift is described as :

f(x) = f(x+k)  The graph is shifted to up k units

f(x) = f(x-k) The graph is shifted down k units.

Vertical shift : none.

The sign of a describes the reflection across the x-axis. −a means the graph is reflected across the x-axis.

Reflection about the x-axis: None

To find the transformation, compare the two functions and check to see if there is a horizontal or vertical shift, reflection about the x-axis, and if there is a vertical stretch.

Answer:

$139,200

Step-by-step explanation:

To find the total cost of the subsidized loan, we need to calculate the total amount of interest that will be added to the loan over the 10-year repayment period. We can use the formula for simple interest:

I = Prt

Where:

I = Interest

P = Principal (the original loan amount)

r = Interest rate (expressed as a decimal)

t = Time (in years)

In this case:

I = 80,000 * 0.074 * 10 = 59,200

The total cost of the loan would be the sum of the principal and the interest:

80,000 + 59,200 = $139,200

So the total cost of the subsidized loan is $139,200.

The factors of the polynomial x³ - 5x² - 12x + 36 are (x-5) and -12(x+3).

What is the Factorisation of Polynomial?

The factors are the polynomials that are multiplied to produce the original polynomial.

The polynomial x³ - 5x² - 12x + 36 can be factored by grouping. We can factor a common factor of x out of the first two terms and the last two terms.

x³ - 5x² - 12x + 36= x(x² - 5x) -12x(1) +36(1)

= x(x-5)(x+1) -12(x+3)

So, the factors of the polynomial x³ - 5x² - 12x + 36 are (x-5)(x+1) and -12(x+3).

We can also factorize this polynomial by using polynomial division.

we can divide x² - 5x by x, remainder will be -5x and we can divide -12x+36 by x+3, remainder will be 0

x³ - 5x² - 12x + 36 = (x(x-5) -12(x+3))

x = 5/2 is a zero of the function f(x) = 2x³ - 5x² - 6x + 15.

What is a function?

A function in mathematics from a set X to a set Y allocates precisely one element of Y to each part of X. The sets X and Y are collectively referred to as the function's domain and codomain, respectively. Initially, functions represented the idealized relationship between two changing quantities.

Here, we have

Given: x = 5/2 is a zero of the function f(x) = 2x³ - 5x² - 6x + 15,

f(x) = 2x³ - 5x² - 6x + 15

When we f(x) = 2x³ - 5x² - 6x + 15 by x-5/2 we get

Remainder = -10

Quotient = 2x² - 6

Divisor = x - 5/2

2x³ - 5x² - 6x + 15 = 2x² - 6 - 10/(x - 5/2)

Bob would take 5 hours to mow the law by himself.

Let us consider, the area of the lawn to be mowed to be x inch².

It is given that the law can be mowed by Abe alone in 3 hours.

We know that,

Rate of work = Work/Time

⇒ rate of work of Abe = area to be mowed(work)/time taken

                                     = (x/3) inch²/hour

Now,

Abe has been working alone for 1/3 hour

⇒work done by Abe alone = rate of work of Abe x time

                                             = (x/3) inch²/hour x 1/3 hour

                                             = x/9 inch²

Remaining work = x - x/9 = 8x/9 inch²

Let, the rate of work of Bob be y inch²/hour.

It is given that the time taken by Abe and Bob to complete the remaining work together is  1 and 2/3 hours, i.e, 5/3 hours.

Therefore,

The rate of work of Abe and Bob when working together

= work ÷ time

=(8x/9) ÷ (5/3)

=8x/15 inch²/hour

⇒ Rate of work of Abe + Rate of work of Bob = 8x/15

⇒ x/3 + y = 8x/15

⇒ y = (8x/15) - (x/3)

⇒ y = 3x/15 = x/5 inch²/hour

Thus, the time taken by Bob to mow the law by himself

= work ÷ rate of work

= x inch² ÷ (x/5) inch²/hour

= 5 hours

So, it would take 5 hours for Bob to mow the lawn alone.

Yes, xk/yk converges to x/y. This can be proven mathematically using the definition of a limit.

If xk converges to x and yk converges to y, then the limit of xk/yk as k approaches infinity is equal to the limit of x/y. This can be expressed algebraically as limk→∞xk/yk = limk→∞x/y, which is equal to x/y. Thus, xk/yk converges to x/y.

To calculate this, we can take a sequence of xk an yk values, and divide every xk by its corresponding yk. For example, if xk = {2, 4, 8, 16, 32} and yk = {1, 2, 4, 8, 16}, then the sequence xk/yk = {2/1, 4/2, 8/4, 16/8, 32/16} = {2, 2, 2, 2, 2}. This sequence converges to 2, which is equal to x/y. Therefore, xk/yk converges to x/y.
