The correct answer would be D., a a right triangle inscribed inside a circle. I just barely did what the instructions said, and it was right. :P
I hope you find this helpful, feel free to mark as brainliest, and good luck! (:

Answer:

D). an equilateral triangle inscribed in a circle

Step-by-step explanation:

Oliver draws a line on a paper and from a point on the line draws  a circle. He then measures the radius of the circle and constructs an arc on the circle from the point on the circumference where the radius meets. This gives a chord because on joining the point where the arc coincides on the circumference and the point where the radius meets the circumference gives you a chord which is equal to the radius of the circle.

       Then join the arc from the center of the circle which gives us a equilateral triangle of equal sides which is equal to the radius of the triangle.

Hence, option D is correct.

Find (fºg)(1)<br> f(x) = x² - 1<br> g(x) = √x <br> A.0<br> B.1<br> C.4 √2<br> D. √8
Savatey [412]

Given:

The function are

f(x)=x^2-1

g(x)=\sqrt{x}

To find:

The value of (f\circ g)(1).

Solution:

We have,

f(x)=x^2-1

g(x)=\sqrt{x}

We need to find the value of (f\circ g)(1).

(f\circ g)(1)=f(g(1))            [\because (f\circ g)(x)=f(g(x))]

(f\circ g)(1)=f(\sqrt{1})            [\because g(x)=\sqrt{x}]

(f\circ g)(1)=f(1)      

(f\circ g)(1)=(1)^2-1                  [\because f(x)=x^2-1]

(f\circ g)(1)=1-1      

(f\circ g)(1)=0      

The value of (f\circ g)(1) is 0.

Therefore, the correct option is A.

Step-by-step explanation:

The area (A) of the shaded part (right triangle ) is calculated as

A = \frac{1}{2} × area of rectangle

   = 0,5 × 4 × 4 = 0.5 × 16 = 8 units²
