The peak wavelength that Earth emits as a blackbody is approximately equal to 9.657 × 10⁻⁶ m.

The Wien's displacement law is a consequence of Planck's radiation law, that states the brightness of a radiative body is a function of wavelength at a given temperature. Wien's displacement law states that peak wavelength is inversely proportional to the temperature (T), in Kelvin. The Wien's displacement law is represented by the following formula:

λ' = b / T

Where:

If we know that b ≈ 2.897 × 10⁻³ m · K and T ≈ 300 K, then the peak wavelength of the Earth is:

λ' = (2.897 × 10⁻³ m · K) / (300 K)

λ' ≈ 9.657 × 10⁻⁶ m

The angles in the picture are calculated and their values are as follows:

Given data

a = 3

b = 3.2

c = 5

using cosine rule for <ABC

b^2 = a^2 + c^2 - 2ac cos B

2ac cos B = a^2 + c^2 - b^2

cos B = (a^2 + c^2 - b^2) / 2ac

cos B = (3^2 + 5^2 - 3.2^2) / 2*3*5

cos B = 23.76/30

B = arc cos (0.792)

B = 37.63 degrees

using sine rule for <BCA

sine B / b = sin C / c

sin 37.63/ 3.2 = sim C / 5

C = arc sin (0.954)

C = 72.55

solving for <CAB

< CAB = 180 - 72.55 - 37.63

The common difference of Uth term is 0

A series of numbers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.

The nth term of the sequence () is given by: If the first term of an arithmetic progression is and the common difference between succeeding members

Formula

a_n=a_1+(n-1)d

a_n = the nth term in the sequence

a_1 = the first term in the sequence

d = the common difference between terms

we gives

a_n=a+(n-1)d

a_11=a+(n-1)d

a_11=a+(11-1)d

a_11=a+10d

a_11=3+10d

10d=-3

d=(-3)/10,  a=3

To find the Uth term of sequence

U_n=a+d(n-1)

U_11=a+d(11-1)

apply the value of a=3,d=(-3)/10

U_11=3+((-3)/10 (11-1) )

U_11=3+((-3)/10 (10) )

U_11=3+(-3)

U_11=0

Therefore, Uth term of arithmetic progression is 0.

Answer:

C The total cost, in dollars, for all binders and notebooks purchased

Step-by-step explanation:

x = the cost of a binder

y =  the cost of a notebook

Mario purchased 4 binders that cost x dollars each and 3 notebooks that cost y dollars each.

4x + 3y = 24

If the given equation represents this situation, which of the following is the best interpretation of 24 in this context?

The total cost, in dollars, for all binders and notebooks purchased.

The inequality that can be used to determine x, the number of outfits Zendaya can purchase  is 329.92 + 65.65x <= 540

The given parameters are:

Budget = $540

New bicycle = $269.88.

4 bicycle reflectors = $10.57 each

Pair of a bike gloves = $17.76.

New biking outfits = $65.65 each.

Let the number of new biking outfits be x

So, we have

New bicycle + 4 * price of bicycle reflectors + Pair of a bike gloves + New biking outfits <= Budget

This gives

269.88 + 4  * 10.57+ 17.76 + 65.65x <= 540

This gives

329.92 + 65.65x <= 540

Solve the inequality

65.65x <= 210.08

Divide by 65.65

x <= 3.2

Hence, the inequality that can be used to determine x, the number of outfits Zendaya can purchase  is 329.92 + 65.65x <= 540

The statements that describe the graph of f(x) are (a) the vertex of f(x) is located at (−3,−1) and (c) there is a y-intercept located at (0,2).

The equation of the function is given as

f(x) = |x + 3| - 1

The above function is an absolute value function.

An absolute value function is represented as

f(x) = a|x - h| + k

Where

Vertex = (h, k)

This means that the vertex of f(x) is located at (−3,−1)

To calculate the y-intercept, we set x = 0

So, we have

f(0) = |0 + 3| - 1

Evaluate

f(0) = 2

This means that there is a y-intercept located at (0,2).

To calculate the x-intercept, we set y = 0

So, we have

|x + 3| - 1 = 0

Evaluate

x = -2

This means that there is a x-intercept located at (-2, 0).

Hence, the statements that describe the graph of f(x) are (a) the vertex of f(x) is located at (−3,−1) and (c) there is a y-intercept located at (0,2).

Because the number behind the 7 was a 1 and not 5 or more, you could not round the 7 up, so it stayed the same.

The value of r² is 0.8673.

Given that x and y are two variables as listed below

We have to find r² the coefficient of determination

x         y         xy          x²        y²

3        2          6           9          4

10      20      200       100      400

------------------------------------------

29     37       289       199      481

Mean x = ( 29 / 5 )

Var X= ( 199 / 5 ) - 29 =10.8,

Mean Y = 7.4, Var Y = ( 481/5 ) - 37 = 96.2 - 37 = 59.2

Now,

r = { n(∑xy ) - (∑x)(∑y) } / √ { n( ∑x²) - (∑x )² ) × [ n(∑y²) - (∑y)² ] }

r = { 5 × 289 - 29 × 37 } / √ { ( 5 ( 199 ) - (29)² ) × [ 5( 481 - ( 37 )² ] }

r = { 1445 - 1073 } / √ { ( 995 - 841 ) × [ 2405 - 1369 ] }

r = 372 / √ { ( 154 ) × [ 1036 ] }

Jeremiah finished 3/4 of his timed math quiz. Of those he attempted, he correctly answered 5/9. What fractional part of the quiz did he get correct?

Answer:

x = -1

y = -2

Step-by-step explanation:

We are given the following equations:

[tex]y = -2x - 4[/tex]

[tex]y = 3x + 1[/tex]

As we can see, the expressions [tex]{-2x - 4}[/tex] and [tex]3x + 1[/tex] are both equal to [tex]y[/tex]. Therefore, we can equate them:

[tex]-2x - 4 = 3x + 1[/tex]

Now we can solve for [tex]x[/tex] by making [tex]x[/tex] the subject of the equation:

⇒ [tex]-2x - 4 -3x = 3x + 1 - 3x[/tex]      [Subtracting [tex]3x[/tex] from both sides]

⇒ [tex]-5x - 4 = 1[/tex]

⇒ [tex]-5x - 4 + 4 = 1 + 4[/tex]                 [Adding 4 to both sides of equation]

⇒ [tex]-5x = 5[/tex]

⇒ [tex]\frac{-5}{-5}x = \frac{5}{-5}[/tex]                                     [Dividing both sides by -5]

⇒ [tex]x = \bf -1[/tex]

Now that we know the value of [tex]x[/tex], we can calculate the value of [tex]y[/tex] by replacing the [tex]x[/tex] with -1 in any of the equations for  [tex]y[/tex] given above:

[tex]y = 3x + 1[/tex]

⇒ [tex]y = 3(-1) + 1[/tex]

⇒ [tex]y = -3 + 1[/tex]

⇒ [tex]y = \bf -2[/tex]

Therefore, the solution to the system of equations is : x = -1, y = -2.

Answer:

x = -1

y = -2

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}y = -2x - 4\\y= 3x + 1\end{cases}[/tex]

Use the method of substitution to solve for x:

[tex]\begin{aligned}& \textsf{Substitute}: & 3x+1 & = -2x-4\\& \textsf{Add $2x$ to both sides}: & 3x+1+2x & = -2x-4+2x\\& \textsf{Combine like terms}: & 5x+1 & = -4\\& \textsf{Subtract $1$ from both sides}: & 5x+1 -1& = -4-1\\& \textsf{Simplify}: & 5x & = -5\\& \textsf{Divide both sides by $5$}: & \dfrac{5x}{5} & = \dfrac{-5}{5}\\& \textsf{Simplify}: & x & = -1\end{aligned}[/tex]

Substitute the found value of x into one of the equations and solve for y:

[tex]\begin{aligned}& \textsf{Equation}: & y& = 3x+1\\& \textsf{Substitute in $x=-1$}: & y & = 3(-1)+1\\& \textsf{Multiply the numbers}: \quad & y & = -3+1\\& \textsf{Simplify}: & y & = -2\\\end{aligned}[/tex]
