how do you know of an exponential fuction is reflected across the x-axis?​

Answers

Answer:

Step-by-step explanation:

A reflection over the x-axis changes all the y-values. The reflection is modeled as -f(x)

For example:

[tex]\sqrt{x}[/tex] would look like --[tex]\sqrt{x}[/tex] .

If the negative sign is outside of the bracket ( what it's called sorry), then it is a reflection over the x-axis

However if the negative sign was inside the bracket: [tex]\sqrt{-x}[/tex] then this would be a reflection over the y axis.

Hope this helps!

find value of X in cos(3x-30°)=sin(7x+50°)​

Answers

Answer:

7

Step-by-step explanation:

Given the expression

cos(3x-30°)=sin(7x+50°)

In trigonometry cosx = sin(90-x)

Hence

Cos(3x-30) = sin(90-(3x-30))

Cos (3x-30) = sin(90-3x+30)

Cos (3x-30) = sin(120-3x)

Substitute into the expression above

Sin(120-3x) = sin(7x+50)

120-3x = 7x+50

Collect like terms

-3x-7x = 50-120

-10x = -70.

x = 70/10

x = 7

Hence the value of x is 7

Answers

Answer:

482895ft^2

Step-by-step explanation:

Given data

Width= 657ft

Length= 735ft

We know that area A

A= Length* Width

A=657*735

A= 482895ft^2

Hence the area is 482895ft^2

Find the value of x. Write your answer in simplest form.

Answers

Answer:

x = 9

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + x² = (9[tex]\sqrt{2}[/tex] )²

2x² = 162 ( divide both sides by 2 )

x² = 81 ( take the square root of both sides )

x = [tex]\sqrt{81}[/tex] = 9

louise decided to purchase a new mountain bike when he saw the sporting good store was offering 20% off their bike. what is the total cost of the mountain bike if the originally price at $249 and louise must pay 7.5% sales tax

Answers

$215.13




First off $249 x 20% = $49.8 so, $249- 49.8 = 199.2 ( the price after deducting the discount), 199.2 x 8% = 15.93 (this is the price of the tax), and 199.2 + 15.93 = $215.13 ( this is the price after the discount and with taxes) :D

The amount of time a certain brand of light bulb lasts is normally distributed with a mean of 1200 hours and a standard deviation of 35 hours. Using the empirical rule, determine what interval of hours represents the lifespan of the middle 68% of light bulbs.

Answers

Answer:

(1165, 1235) (hours)

Step-by-step explanation:

The "middle 68%" of a set of normally distributed data is that data that lies within ONE standard deviation of the mean:

(1200 - 35, 1200 + 35), or

(1165, 1235) (hours)

This is an application of the Empirical Rule.

The interval of hours represents the lifespan of the middle 68% of light bulbs is (1165, 1235) (hours).

What is the standard deviation?

It is a measurement of statistical data dispersion. The degree to which the value varies is known as dispersion.

With a mean of 1200 hours and a standard variation of 35 hours, the length of time a certain brand of light bulb lasts is typically distributed.

The data that is within one standard deviation of the mean is referred to as the "middle 68 percent" of a collection of normally distributed data:

The interval of hours represents the lifespan of the middle 68% of light bulbs is found as;

(1200 - 35)=1165

( 1200 + 35)=1235

(1165, 1235) (hours)

Hence,the interval of hours represents the lifespan of the middle 68% of light bulbs is (1165, 1235) (hours).

[tex]y = 28 \sin(\frac{\pi}{6} - \frac{2\pi}{3}) + 49[/tex]

Step by Step Explanation

Given

See attachment for table

Required

Determine the sinusoidal function

The sinusoidal function is represented as:

[tex]y = A \sin(Bx + C) + D[/tex]

Where

[tex]|A| = Amplitude[/tex]

And it is calculated as:

[tex]A = \frac{1}{2}[Highest - Least][/tex]

From the table:

Highest = 77 and Least = 21

So:

[tex]A = \frac{1}{2}[77 - 21][/tex]

[tex]A = \frac{1}{2}[56][/tex]

[tex]A = 28[/tex]

B is calculated as:

[tex]Period = \frac{2\pi}{B}[/tex]

The period is 12 i.e. 12 months

So:

[tex]\frac{2\pi}{B} = 12[/tex]

[tex]B = \frac{2\pi}{12}[/tex]

[tex]B = \frac{\pi}{6}[/tex]

C is calculated as:

[tex]\frac{C}{B} = -4[/tex]

[tex]C = -4 * B[/tex]

[tex]C = -4 * \frac{\pi}{6}[/tex]

[tex]C = -2 * \frac{\pi}{3}[/tex]

[tex]C = -\frac{2\pi}{3}[/tex]

Lastly, D is calculated as:

[tex]D = Least + A[/tex]

So:

[tex]D =21 + 28[/tex]

[tex]D=49[/tex]

So, the function is:

[tex]y = A \sin(Bx + C) + D[/tex]

[tex]y = 28 \sin(\frac{\pi}{6} - \frac{2\pi}{3}) + 49[/tex]

Answer:

y=28 sin (pi/6 t - 7pi/6)+49

Ms. Smith and Mr. Roberts are running a race. Ms. Smith runs 8, 305 feet. Mr. Roberts runs 2 miles. How many feet further does Mr. Roberts run? (Reminder: 1 mile = 5,280 feet)

Answers

Answer:

Mr. Roberts runs 2,255 more feet then Ms. Smith.

Step-by-step explanation:

So I took 5,280 + 5,280 = 10,560 so now I can just take Ms. Smith's 8,305 and subtract it from 10,560 which gave me 2,255 so Mr. Roberts runs 2,255 more feet then Ms. Smith.

anyone know this?????

Answers

Answer:

(- 2, 1 ) and (1, 4 )

Step-by-step explanation:

Given the 2 equations

y = - x² + 5 → (1)

- x + y = 3 → (2)

Rearrange (2) expressing y in terms of x by adding x to both sides

y = x + 3 → (3)

Substitute y = x + 3 into (1)

x + 3 = - x² + 5 ( subtract - x² + 5 from both sides )

x² + x - 2 = 0 ← in standard form

(x + 2)(x - 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 2 = 0 ⇒ x = - 2

x - 1 = 0 ⇒ x = 1

Substitute these values into (3) for corresponding values of y

x = - 2 : y = - 2 + 3 = 1 ⇒ (- 2, 1 )

x = 1 : y = 1 + 3 = 4 ⇒ (1, 4 )
