Answer:

30 miles

Step-by-step explanation:

Before finding the perimeter of the given right angled triangle, we need to find the length of a.

We'll be using pythagoras property to find the value of a.

According to the pythagoras property, sum of the squares of base and perpendicular is equivalent to the square of hypotenuse.

Here,

  • Hypotenuse = 13 mi
  • Base = 12 mi
  • Perpendicular (a) = ?

→ H² = B² + P²

→ H² - B² = P²

→ (13 mi)² - (12 mi)² = a²

→ 169 mi² - 144 mi² = a²

→ 25 mi² = a²

→ √(25 mi²) = a

→ <u>5 mi = a</u>

We know that,

  • Perimeter of ∆ = Sum of all sides

→ Perimeter = 13 mi + 12 mi + a

→ Perimeter = 13 mi + 12 mi + 5 mi

→ Perimeter = 30 miles

\therefore <u>Perimete</u><u>r</u><u> </u><u>of</u><u> </u><u>the </u><u>triangle</u><u> </u><u>is</u><u> </u><u>3</u><u>0</u><u> </u><u>mi</u><u>l</u><u>e</u><u>s</u><u>.</u>

(8Q) Tell whether the function exhibits damped oscillation. If it does, identify the damping factor and tell whether the damping
dezoksy [38]

Answer:

Option c.

No damping

Step-by-step explanation:

We can easily solve this question by using a graphing calculator or any plotting tool.

The function is

f(x) = (√11)*cos(3.7x)

Which can be seen in the picture below

We can notice that f(x) is a cosine with maximum amplitude of  (√11). Neither this factor nor the multiplication of x by 3.7 serve as a damping factor since they are constants.

f(x) does not present any dampening

ITS TIMED PLEASE HELP​
Lubov Fominskaja [6]

Answer:

The graph of the function f(x)=\frac{1}{2}x^{2}-4x+5 has a minimum located at (4,-3)

Step-by-step explanation:

we know that

The equation of a vertical parabola in vertex form is equal to

f(x)=a(x-h)^{2}+k

where

a is a coefficient

(h,k) is the vertex of the parabola

If a > 0 the parabola open upward and the vertex is a minimum

If a < 0 the parabola open downward and the vertex is a maximum

In this problem

The coefficient a must be positive, because we need to find a minimum

therefore

Check the option C and the option D

Option C

we have

f(x)=\frac{1}{2}x^{2}-4x+5

Convert to vertex form

f(x)-5=\frac{1}{2}x^{2}-4x

Factor the leading coefficient

f(x)-5=\frac{1}{2}(x^{2}-8x)

f(x)-5+8=\frac{1}{2}(x^{2}-8x+16)

f(x)+3=\frac{1}{2}(x^{2}-8x+16)

f(x)+3=\frac{1}{2}(x-4)^{2}

f(x)=\frac{1}{2}(x-4)^{2}-3

The vertex is the point (4,-3) ( is a minimum)

therefore

The graph of the function f(x)=\frac{1}{2}x^{2}-4x+5 has a minimum located at (4,-3)
