Answer:  102.9 m

<u>Step-by-step explanation:</u>

First, use Pythagorean to find the length of AC

 AB²  +  AD²  = AC²

 50²  +   80²  = AC²

2500 + 6400 = AC²

             8900 = AC²

             94.34 = AC

Next, subtract 15 (the diameter of the circle) from AC to find the length of the straight line.

94.34 - 15 = 79.34

Next, find the circumference of the circle

C = πd

C = 15π

They are only walking around 1/2 of the circle so divide it by 2.

(1/2)C = (15/2)π

          ≈ 23.56

Add the straight line (79.34) and the half circumference (23.56) to find the total distance traveled.

79.34 + 23.56 = 102.9

Miss Stevens drove through a total of 36 intersections on her way home from work last week at four of every 16 intersections Mis
Nostrana [21]

Answer:

8 intersections

Step-by-step explanation:

Miss Stevens drove through a total of 36 intersections on her way home from work last week.

At four of every 16 intersections Miss Stevens had to stop for a red light before she could drive through .

This is calculated as:

36 intersections ÷ 16 intersections

= 2 4/16

= 2 1/4

At four of every 16 intersections Miss Stevens had to stop for a red light before she could drive through .

4 of every 16 intersections = stop for a red light

Hence:

16/4 = 4 intersections

Hence: 4 intersections = 1 stop for a read

The number of intersections that Miss Stevens had to stop for a red light is:

2 × 4 intersections = 8 intersections

1. y = log x
Nuetrik [128]

Answer:

Domain {x : x  > 1}

Range {y : y ∈ R}

Vertical asymptote x = 0

x-intercept (1, 0)

End behavior consistent

Graph attached down

Step-by-step explanation:

Let us study the equation:

∵ y = log(x)

→ It is a logarithmic function, so no negative values for x

∴ Its domain is {x : x  > 1}

∴ Its range is {y : y ∈ R}, where R is the set of the real numbers

→ An asymptote is a line that a curve approaches, but never touches

∵ x can not be zero

∴ It has a vertical asymptote whose equation is x = 0

→ x-intercept means values of x at y = 0, y-intercept means

   values of y at x = 0

∵ x can not be zero

∴ There is no y-intercept

∵ y can be zero

∴ The x-intercept is (1, 0)

→ The end behavior of the parent function is consistent.

   As x approaches infinity, the y-values slowly get larger,

   approaching infinity

∵ y = log(x) is a parent function

∴ The end behavior is consistent

→ The graph is attached down
