Answer:

  • 66.56 cm

Step-by-step explanation:

<u>The figure consist of:</u>

  • 1. A rectangle with sides 10 cm and 17 cm
  • 2. A quarter circle

<u>The perimeter is:</u>

  • P = 1/4C + 2*10 + 17 + (17 - 8) + 8
  • P = 1/4*2*3.14*8 + 54 = 66.56 cm

Write the set using interval notation. <br><br> {x | x ≠ −2, 8}
Viefleur [7K]

As a set it tells that x can be anything but -2 and 8. For -2, we write our interval so that it includes everything but 2.

(-∞, -2) ∪ (-2,....)

We use the union because it could be in one interval or the other, and we use parentheses to exclude -2. Now we repeat it with 8.

(-..., 8) ∪ (8, ∞).

Lastly we put both together.


The set in interval notation is (-∞, -2) ∪ (-2, 8) ∪ (8,∞)

Prove : the graphs of the function f(x)=x4<br> and g(x)=x3-x2 have aunique intersection<br> point.
vagabundo [1.1K]

Answer:

The unique intersection point for the given functions which is at x = 0.

The intersection point is (0,0)

Step-by-step explanation:

We are given the following information in the question.

f(x) = x^4\\g(x) = x^3-x^2

We have to find the intersection point.

Equating the two equations we get,

x^4 = x^3 - x^2\\x^4 - x^3 + x^2 = 0\\x^2(x^2-x +1) = 0\\x^2 =0, x^2-x +1 = 0\\x = 0, x = 0, x^2-x +1=0

Since the quadratic equation gives complex root, thus there is a unique intersection point for the given functions which is x = 0.

The attached image shows the graph for the given function.

The red line represent f(x) and blue line represent g(x).

The intersection point is (0,0)

In a right triangle the leg opposite to the acute angle of 30° is 7 in. Find the
Kobotan [32]

Answer:

in the explanation

Step-by-step explanation:

In a 30-60-90 triangle, the ratio of the leg opposite to 30 to the leg opposite to 60 to the hypotenuse is 1:\sqrt{3\\}:2.

So, the 7 inch leg is the 1, the other leg is 7\sqrt{3} in and the hypotenuse is 14 in.

Hope this helps!
