Answer:

The function [tex]f(x)=x^3+\mathbf{1}x^2-\mathbf{17}x+\mathbf{15}[/tex]

Step-by-step explanation:

We have the polynomial having zeros 1,3,-5

We can write them as:

x=1,x=3,x=-5

or

x-1=0, x-3=0,x+5=0

Multiplying all terms:

[tex](x-1)(x-3)(x+5)\\=(x(x-3)-1(x-3))(x+5)\\=(x^2-3x-1x+3)(x+5)\\=(x^2-4x+3)(x+5)\\=(x^2-4x+3)+5(x^2-4x+3)\\=^3-4x^2+3x+5x^2-20x+15\\=x^3-4x^2+5x^2+3x-20x+15\\=x^3+x^2-17x+15[/tex]

So, The function [tex]f(x)=x^3+\mathbf{1}x^2-\mathbf{17}x+\mathbf{15}[/tex]

Answer:

The correct answer is:

The graph will be the same width as the parent graph f(x) = x², but the vertex has been shifted to (1, 2).

Step-by-step explanation:

Since the value of a, the coefficient of x², is 1, this means the graph has not been stretched or shrunk. However, since the function is different than f(x)=x², we know that the vertex is not at (0, 0). We can write the function in vertex form to find the new vertex.

To write the function in vertex form, we find the value of b/2. The value of b in this function is -2; -2/2 = -1. We then square this: (-1)² = 1. This is what we add and subtract to the function (we must do both to preserve equality), giving us:

f(x) = x²-2x+1+3-1

The first three terms of this function can be written as the square (x+(b/2))²; this is (x-1)², and gives us f(x) = (x-1)²+3-1. Combining like terms, we have:

f(x) = (x-1)²+2

This is vertex form, f(x) = a(x-h)²+k, where (h, k) is the vertex. This means the vertex is at (1, 2) instead of (0, 0).

Answer:

0.002,0.005,0.02,0.025,0.05,0.052

Answer:

(1/2, 6).

Step-by-step explanation:

Turning points in a graph may exist whenever the derivative equals 0. Hence, let’s differentiate and then solve our function.

We have:

[tex]\displaystyle y=8x^2+\frac{2}{x}[/tex]

Take the derivative of both sides with respect to x:

[tex]\displaystyle y^\prime=16x-\frac{2}{x^2}[/tex]

Simplify:

[tex]\displaystyle y^\prime=\frac{16x^3-2}{x^2}[/tex]

We will now set this equal to 0 and solve for x. Hence:

[tex]\displaystyle \begin{aligned} 0&=\frac{16x^3-2}{x^2} \\ 0&=16x^3-2 \\ 2&=16x^3 \\ \frac{1}{8}&=x^3 \\ \frac{1}{2}&=x \end{aligned}[/tex]

Hence, the graph turns at x=1/2. This is the x-coordinate.

Then it follows that the y-coordinate will be:

[tex]\displaystyle{\begin{aligned} y&=8(\frac{1}{2})^2+\frac{2}{\frac{1}{2}} \\ y&=8(1/4)+2(2) \\ y&=2+4 \\ y&=6\end{aligned}[/tex]

Hence, our coordinate Is (1/2, 6).

Answer:

[tex]x=30[/tex]

Step-by-step explanation:

First, let us notice that the ticks on the side of this quadrilateral indicate that the lengths of the sides are equal.

From this, we can create the following equation based on the perimeter of this shape.

[tex]28+28+x+x=116[/tex]

Now, we can solve this equation for x by first combining like terms

[tex]2x+56=116[/tex]

Now, we can subtract 56 from each side

[tex]2x=60[/tex]

And now divide each side by 2

[tex]x=30[/tex]

Just to check out answer, we can plug this x-value into our original perimeter equation to see if it is correct

[tex]28+28+30+30=116\\\\56+60=116\\\\116=116[/tex]

Answer:

The ball will spend 10,730.4012 microseconds in the strike zone

Step-by-step explanation:

Here, we want to calculate the time spent by a ball in the strike zone given the distance across the strike zone and the speed of the ball

Mathematically, we have ;

time = distance/speed

Before we proceed to use this formula, we need to have the parameters in the same units

So let’s convert 17 inches to miles

Mathematically;

1 inch = 1.578 * 10^-5 mile

So 17 inches = 1.578 * 10^-5 * 17 = 0.00026826 miles

So let’s now calculate the time

That will be;

0.00026826/90 = 0.000002980667 hours

It will be best if we convert this to seconds

Mathematically,

60 seconds = 1 minute

60 minutes = 1 hour

So the number of seconds in an hour is 60 * 60 = 3600 seconds

= 0.000002980667 * 3600 = 0.0107304012

Mathematically, 1 second = 10^6 microseconds

Thus multiplying 0.0107304012 by 10^6

we have; 10,730.4012 micro seconds

Answer: 15cm by 20cm

3cm by 4cm

9cm by 12cm

Step-by-step explanation:

From the question, we are informed that a 12 cm by 16 cm painting hangs in a museum. We are given several options and told to choose the paintings' dimensions that are proportional to the original painting. This will be:

12cm by 16cm when divided by 4 gives 3cm by 4cm. This means that we have to look out for the options that are in the ratio 3:4.

A. 6 cm by 12 cm

6cm by 12cm reduced to lowest term gives 1:2

B. 15 cm by 20 cm

15cm by 20cm reduced to lowest term gives 3:4

C. 3 cm by 4 cm

D.6 cm by 9 cm

6cm by 9cm reduced to lowest term gives 2:3.

E. 9 cm by 12 cm

9cm by 12cm reduced to lowest term gives 3:4.

Therefore the correct options are:

15cm by 20cm

3cm by 4cm

9cm by 12cm
