The approximate surface area of this right triangular prism is 193.2cm

<h3>Surface area of prism</h3>

The surface area of a triangular prism is expressed as:

Surface area = (Perimeter of the base × Length of the prism) + (2 × Base Area)

Perimeter of the base = 6 + 6 + 6

Perimeter of the base = 18cm

Length of the prism = 9cm

Base area = 1/2 * 5.2 * 6
Base area  = 15.6cm

Determine the surface area

Surface area = (18 * 9) + 2(15.6)

Surface area = 162 + 31.2

Surface area = 193.2 cm

Hence the approximate surface area of this right triangular prism is 193.2cm

Find the x-value of the removable discontinuity of the function. ​
Sergio039 [100]

Answer:

x=2

Step-by-step explanation:

f(x)=\frac{x^2-4}{x^2-12x+20}

Factor the numerator and denominator:

f(x)=\frac{(x-2)(x+2)}{(x-2)(x-10)}

We can remove (x-2) from the function:

f(x)=\frac{x+2}{x-10}

(x-2) is a removable discontinuity.

The x-value of x-2 is x=2.

Vertex (0,1) x intercepts is - 1 and 1 what is the equation of the parabola?
MrRa [10]
\bf y=a(x-{{ h}})^2+{{ k}}\\&#10;x=a(y-{{ k}})^2+{{ h}}\qquad\qquad  vertex\ ({{ h}},{{ k}})

those are the vertex form of a parabola... so hmmm
the vertex of this one is at 0,1 and intercepts or "solutions" are at -1 and 1, so is opening downwards, notice the picture below

that means, the squared variable is the "x", thus the form is \bf y=a(x-{{ h}})^2+{{ k}}

now, we know the vertex is at 0,1, and two x-intercepts of \pm 1,0

thus      \bf y=a(x-{{ h}})^2+{{ k}}\qquad &#10;\begin{cases}&#10;h=0\\&#10;k=1\\&#10;when&#10;\\&#10;x=\pm 1\\&#10;y=0&#10;\end{cases}&#10;\\\\\\&#10;\textit{so.. hmmm let us use the point ... say hmmm 1,0}&#10;\\\\&#10;y=a(x-{{ h}})^2+{{ k}}\implies 0=a(1-0)^2+1

solve for "a", to see what that coefficient is, then plug it back in the vertex form equation

5. An attacker swings a board with a mass of 2 kg toward a victim. The acceleration is 10 m/s2 when the board hits the victim. H
suter [353]

The force exerted on victim is 20 newton

<em><u>Solution:</u></em>

An attacker swings a board with a mass of 2 kg toward a victim

The acceleration is 10 m/s^2 when the board hits the victim

To find: Force exerted on victim

<em><u>The force is given by formula:</u></em>

F = mass \times acceleration

From given,

mass = 2 \text{ kg }\\\\Acceleration = 10 m/s^2

<em><u>Substituting the values in formula,</u></em>

Force = 2 \times 10 = 20

Thus force exerted on victim is 20 newton
