Answer: 60° angle construction

Step-by-step explanation:

The geometric construction shown is on a 60 degree angle construction with a compass and straightedge or ruler. The pattern followed is that of making an equilateral triangle. Note that each three interior angles of an equilateral triangle is 60°. Using one of those angles we can get the desired angle in the following steps:

1. Draw a line segment which will become one side of the angle. The exact length is not that important. Label this line AB. A will be the angle's vertex.

2. Set the compasses on A; set its width to any convenient expansion

3. Draw an arc across AB and up over above the point A.

4. Without changing the compasses' width (expansion), move the compasses to the point where the arc crosses AB, and make an arc that crosses the first one.

5. Draw a line from A, through the intersection of the two arcs.

6. Done. The angle CAB has a measure of 60°

N(t) = 100,000e−(t − 10)2/8

mafiozo [28]

The approximation of the slope of the graph at t = 10 days using this secant lines are 11750 and -11750, respectively.

<h3>How to determine the slope of the secant lines?</h3>

<u>(a) t = 10 days and a day earlier</u>

This means that:

t = 10 and t = 9

The function is given as:

$N(t) = 100000e^{\frac{-(t - 10)^2}{8}}$

Calculate N(10)

$N(10) = 100000e^{\frac{-(10 - 10)^2}{8}}$

Evaluate

N(10) = 100000

Next, calculate N(9)

$N(9) = 100000e^{\frac{-(9 - 10)^2}{8}}$

Evaluate

N(9) = 88249.6902585

The slope is then calculated using"

$m = \frac{N(10) - N(9)}{10 - 9}$

This gives

$m = \frac{100000 - 88249.6902585}{10 - 9}$

Evaluate

m = 11750.3097415

Approximate

m = 11750

<u>(b) t = 10 days and a day later</u>

This means that:

t = 10 and t = 100

The function is given as:

$N(t) = 100000e^{\frac{-(t - 10)^2}{8}}$

In (a), we have:

N(10) = 100000

Next, calculate N(11)

$N(9) = 100000e^{\frac{-(11 - 10)^2}{8}}$

Evaluate

N(11) = 88249.6902585

The slope is then calculated using:

$m = \frac{N(11) - N(10)}{11 - 10}$

This gives

$m = \frac{88249.6902585 - 100000}{11 - 10}$

Evaluate

m = -11750.3097415

Approximate

m = -11750

Hence, the approximation of the slope of the graph at t = 10 days using this secant lines are 11750 and -11750, respectively.

I need help on this help help I’ll give out some money

frozen [14]

<h3>a) Never</h3>

{All angles of a rectangle are right}

<h3>b) Always</h3>

{all sides of a rhombus are the same, 4×13=52}

<h3>c) Always</h3>

{oposite angles of a paralleogram are congruent}

<h3>d) Never</h3>

{parallel sides has the same slope}

<h3>e) Always</h3>

{square has all sides of the same length, so it is rhombus}

<h3>f) Sometimes</h3>

{Only if it has angles of 90°}

Mira has breakfast at a restaurant. She leaves a 20% tip of $1.80

Sedaia [141]

Let x be the price of the breakfast.

We know that 20 percent of x is 1.80

Let's write this as a mathematical equation

0.2 x = 1.8

Let's divide both sides by 0.2 to isolate the x

x = 1.8 / 0.2

= 9

The price of the breakfast was $9.

Have an awesome day! :)
