Answer:

It is not a one to one function

Step-by-step explanation:

Required

Determine if f(x) = round(x) is a one to one function

This question is best answered using illustrating values;

Let x = 1.1

f(x) = round(x) becomes

f(1.1) = round(1.1)

f(1.1) = 1

Let x = 1.3

f(x) = round(x) becomes

f(1.3) = round(1.3)

f(1.3) = 1

Notice that for the two values of x, f(x) has the same value of 1.

This two illustrating values can be used to conclude that the fuction is not one-to-one.

Find the value of x. Round to the nearest tenth. 37 17.3 units​
dlinn [17]

Answer:

x ≈ 21.7

I rounded to the nearest tenth because the values are given in tenths. The first few digits of x are below if you are rounding to something else, as the image is cut out.

Answer:

(a)x=128 degrees

(b)\angle APD\neq 116^\circ

Step-by-step explanation:

\angle ABD+\angle CBD =180^\circ$ (Linear Postulate)\\\angle ABD+116^\circ =180^\circ\\\angle ABD=180^\circ-116^\circ\\\angle ABD=64^\circ

(a) Now:

\angle AOD=2 \times \angle ABD$ (Angle at the centre is twice the  angle at the circumference)\\x=2 \times 64^\circ\\x=128^\circ

(b)

\angle APD=2 \times \angle ABD$ (Inscribed Angle Theorem)\\\angle APD=2 \times 64^\circ\\ \angle APD=128^\circ

\angle APD\neq 116^\circ
