Find the arc length of the semicircle.

mafiozo [28]

The arc length of the semicircle is 15.7

<h3>Calculating Arc length </h3>

From the question, we are to determine the arc length of the semicircle

Arc length can be determined by using the formula,

Arc length = θ/360° × 2πr

Where θ is the angle subtended by the arc

and r is the radius of the circle

In the given diagram,

θ = 180°

and r = 10/2

r = 5

Thus,

The arc length of the semicircle = 180°/360° ×2×3.14×5

The arc length of the semicircle = 1/2×2×3.14×5

The arc length of the semicircle = 15.7

Hence, the arc length of the semicircle is 15.7

If f(x) = x² + 1 for what x value is f(x) = 2?

MaRussiya [10]

Answer:

x = ±1

Step-by-step explanation:

Step 1: Define variables

f(x) = x² + 1

f(x) = 2

Step 2: Substitute

2 = x² + 1

Step 3: Solve for <em>x</em>

0 = x² - 1

0 = (x - 1)(x + 1)

x - 1 = 0

x = 1

x + 1 = 0

x = -1

∴ x = ±1

On a recent day 8 euros were worth 9 dollars and 24 euros were worth 24 dollars write an equation of the form y = kx

slavikrds [6]

<h3><u>Question:</u></h3>

On a recent day, 8 euros were worth $9 and 24 euros were worth $27. Write an equation of the form y = kx to show the relationship between the number of euros and the value in dollars.

<h3><u>Answer:</u></h3>

y = 1.125x is the equation to show the relationship between the number of euros and the value in dollars.

<h3><u>Solution:</u></h3>

Given that On a recent day 8 euros were worth 9 dollars and 24 euros were worth 24 dollars

Let "y" be the value in dollars

Let "x" be the number of euros

We have to write a equation in form of y = kx

<em><u>8 euros were worth 9 dollars</u></em>

"k" is found as follows:

$k = \frac{\text{value in dollars}}{\text{number of dollars}}$

$k = \frac{9}{8}$

Therefore, equation of y = kx is given as:

$y = \frac{9}{8}x$

$y = 1.125x$

To check the equation, use the another given value

24 euros were worth $27

$y = 1.125 \times 24\\\\y = 27$

Hence the equation y = 1.125x is correct
