In this given graph, f(x) is a polynomial modeling the Pi-guy, the math superhero, flying around. Write an equation in terms of

saw5 [17]

Answer:

The given transformation are;

1) Parent function = f(x)

2) Transformation A = f(x + 5)

3) Transformation B = f(x) + 3

Step-by-step explanation:

1. The question being asked in the problem is the representation of the transformation of the given figure which is a function (the curved line that runs through the hands of Pi-guy in the drawing) in functional notation using f(x) to represent the function

2. Try using changes along the x axis as changes in the independent variable, x, in the function f(x) as follows;

Initial position of the parent function = f(x)

Transformation A, which is a translation, 5 units to the right along the x axis = f(x + 5)

Transformation along the y-axis where x = 0, as addition or subtraction to the parent function

Therefore;

Transformation B, which is a translation, 3 units to the up along the y-axis with x at 0 = f(x) + 3

3. The outline of the answers can be presented as follows

The given transformation are;

1) Parent function = f(x)

2) Transformation A = f(x + 5)

3) Transformation B = f(x) + 3

4. The above expression can be checked by considering the curve of the function as a figure and performing the given translations on all points on the figure

Can someone help me Determine the intercepts of the line.

slavikrds [6]

Greetings!

To find the y-intercept, we can arrange the equation in slope y-intercept form:
$y=mx+b$

Rearrange:
$y+1=3(x-4)$

$y+1=3x-12$

$y=3x-13$

The y-intercept is: -13
$\boxed{(0,-13)}$

To find the x-intercept, we can input the value <<0>> in the place of y, as every x-intercept only occurs when y=0:
$(0)=3x-13$

Solve for x:
$0=3x-13$

$13=3x$

$\frac{13}{3}= \frac{3x}{3}$

$x=\frac{13}{3}$

The x-intercept is: $\frac{13}{3}$
$\boxed{(\frac{13}{3},0)}$

I hope this helped!

If the surface area of the box in the diagram is 204.25 square feet, what is the value of ‘x’?

Alexandra [31]

Note: Consider x be the breadth of the box.

Given:

The surface area of the box is 204.25 square feet.

Length of the box = 10 ft

Breadth of the box = x ft

Height of the box = 6.5 ft

To find:

The value of x.

Solution:

The surface area of a cuboid is:

$SA=2(lb+bh+hl)$

Where, l is length, b is breadth and h is height of the cuboid.

Putting $SA=204.25, l=10,\ b=x,\ h=6.5$ in the above formula, we get

$204.25=2(10\times x+x\times 6.5+6.5\times 10)$

$204.25=2(10x+6.5x+65)$

$204.25=2(16.5x+65)$

Using distributive property, we get

$204.25=2(16.5x)+2(65)$

$204.25=33x+130$

$204.25-130=33x$

$74.25=33x$

Divide both sides by 33.

$\dfrac{74.25}{33}=x$

$2.25=x$

Therefore, the correct option is B.
