The perimeter of the given quarter circle is 24.997 cm.

Step-by-step explanation:

Step 1:

The perimeter of a circle is 2π times its radius.

The given figure is only a quarter circle so we divide the entire circle's perimeter by 4 to get this figures circular portions perimeter and add it with the lengths of the two sides of the quarter circle.

The perimeter of a circle = 2 \pi r.

Step 2:

The given circle has a radius of 7 cm and we take \pi = 3.142.

The perimeter of the full circle = 2 (3.142)(7) = 43.988.

The perimeter of the circular portion = \frac{43.988}{4} = 10.997 cm.

The two sides measure 7 cm each.

So the perimeter of the given figure = 10.997 + 7 + 7 = 24.997 cm.

Triangles triangle ABC and triangle DEF are similar. Find the angles of these triangles if Mesurements of angle A=100 degrees, a
beks73 [17]

Answer:

<D = 100

<E =30

<F =50

Step-by-step explanation

Given that triangles triangle ABC and triangle DEF are similar, this means that their angles are congruent i.e

<A = <D

<B = <E

<C = <F

Given

<A = 100 then <D = 100

<B = 30°, then <E = 30°

To get <F, we will use the expression

<D+<E+<F = 180 (sum of angles in a triangle is 180°)

100+30+<F = 180

130+<F = 180

<F = 180-130

<F = 50°

Hence the measure of <F is 50°

Which statement is true about the discontinuities of the function f(x) = x-5/3x^2-17x-28
o-na [289]
1) function f(x)

              x - 5
f(x) = ----------------
          3x^2 - 17x - 28

2) factor the denominator:

3x^2 - 17x  - 28 = (3x + 4)(x - 7)

                        x - 5
=> f(x) = -----------------------
                (3x + 4) (x  - 7)

3) Find the limits when x → - 4/3 and when x → 7

Lim of f(x) when x → - 4/3 = +/- ∞

=> vertical assymptote x = - 4/3

Lim of f(x) when x → 7 = +/- ∞

=> vertical assymptote x = 7

Answer: there are assympotes at x = 7 and x = - 4/3
