Step-by-step explanation:

first : the sum of all angles in a triangle is always 180°.

second : the law of sine

a/sin(A) = b/sin(B) = c/sin(C)

a, b, c are the sides, A, B, C are the the corresponding opposite angles.

therefore,

angle J = 180 - 71 - 46 = 63°

j/sin(J) = k/sin(K)

11/sin(63) = k/sin(46)

k = 11×sin(46)/sin(63) = 8.880673249... m

The solution for the expression ( -8x³) ⁻ ⁴/₃ = 1 / 16x⁴

Given expression is ( -8x³) ⁻ ⁴/₃

= ( -8x³) ⁻ ⁴/₃

It can be written as

We know that 8 = 2³ then

= ((-2x)³) ⁻ ⁴/₃

= ((-2x)³* ⁻ ⁴/₃

On the exponents '3' will be canceled then we get

= (-2x) ⁻ ⁴

We know that x ⁻ ¹ can be written as 1/x, then

= 1/(-2x)⁴

= 1 / 16x⁴

∴  ( -8x³) ⁻ ⁴/₃ = 1 / 16x⁴

Using linear functions, it is found that:

a) The cheaper costs are given as follows:

b) Due to the same cost per game and higher cost for the pair of shoes, bowling alley A will never be cheaper than bowling alley B.

A linear function is modeled by:

y = mx + b

In which:

For this problem, we have that:

Hence the cost functions are given as follows:

The costs are equal when:

A(x) = B(x)

3.75 + 4x = 2.5 + 4.5x

0.5x = 1.25

x = 1.25/0.5

x = 2.5.

Hence the cheaper costs are given as follows:

Alley B has the lower initial cost due to the lower cost for the pair of shoes.

For item b, if we increase the cost per game by $0.50 for alley A, we have that:

A(x) = 4.5x + 3.75.

Hence:

Due to the same cost per game and higher cost for the pair of shoes, bowling alley A will never be cheaper than bowling alley B.

a)The acceleration, in km/h², in the first 15 mins = 200  km/h².

b) The distance between the two cities = 125 km.

c) The average speed during 20 the journey =  62.5  km/hr.

For the given question;

Every horizontal block is 1/8 hour = 7.5 minutes long.

Each vertical block has a speed of 10 km/hr:

The table drawn as per the data given in the table:

Time                    Velocity  km/hr

0 Min  ( 0 hr)   --->         0

15 Min (1/4 hr)   -->       50

45 Min (3/4 hr)  -->      50

60 MIn  ( 1 hr)      -->    100

90 Min  ( 3/2 hr)   --->  100

120 Min ( 2hr)     --->    0

The formula for acceleration:

Part a: Acceleration = final velocity - initial velocity / final time - initial time

Acceleration in the first 15 minutes:  (1/4 hr)  =  (50 - 0)/(1/4 - 0)  

= 50/(1/4)

=200

Thus, acceleration in the first 15 minutes is 200 kmph.

Part b: Distance among two cities:

= (1/2)(0 + 50)(1/4 - 0)  + 50 * (3/4 - 1/4)  + (1/2)(50 + 100)(1 - 3/4)  + 100 * (3/2 - 1) + (1/2)(100 + 0)(2 - 3/2)

=  25/4  + 25 + 75/4   + 50 + 25

= 125

The difference distance for two cities is 125 kilometers.

Part c: Average speed = distance/2

Average Travel Speed = 125/2 = 62.5 km/hr

Therefore,

a: Acceleration in the first 15 minutes = 200  km/h²

b: The distance between two cities is 125 kilometers.

Function composition exists a mathematical procedure where two functions, f and g, exists taken and a function, h = g ⁰ f, exists produced such that h(x) = g(f(x)). The function g is used in this operation on the outcome of applying the function f to x.

Let the function be f(x) = 10x -10

We want to find (f ⁰ f⁻¹)(d)

To differentiate with respect to X, then we get

[tex]F^{-1}[/tex](x) = 10

To find the value of (f ⁰ f⁻¹)(d)

F([tex]f^{-1}[/tex](x)) = F(10)

F([tex]f^{-1}[/tex](x)) = 10x - 10

substituting the values in the above equation, then

F([tex]f^{-1}[/tex](x)) = 10(10) - 10

simplifying the above equation, we get

F([tex]f^{-1}[/tex](x)) = 100 -10

The negative exponent of 1/16 is   2⁻^{4}.

A statement is considered to be an expression if it has a minimum of two numbers or variables as well as at least one mathematical action.

The multiplicative inverse of the base raised to the power opposite to the provided power is the definition of a negative exponent. In plain English, we write the number's reciprocal and solve it just like positive exponents. For instance, (2/3)-2 may be represented as (3/2)2.

1/16 = 16⁻¹  

1/16 = 16⁻¹  = 4⁻²

1/16 = 16⁻¹  = 4⁻² =  (2^2)⁻²  =  2⁻^{4} .

1/16 =   2⁻^{4} .

The correct option is (A) The y-coordinate is -5. If point D(-1, 5) is reflected across the x-axis then the coordinates of D’ are (-1, -5).

Geometry. The x-coordinate remains constant when a point is reflected across the x-axis, but the y-coordinate is assumed to be the additive inverse. Point (x, y) is reflected across the x-axis as (x, -y).

Determine the location of the mirror line before reflecting an object on a coordinate plane. Simply multiply the coordinate of the point by -1 to reflect over the axis. Use the symbols. Simply multiply the coordinate of the point by -1 to reflect over the axis.

Given coordinates of D= (-1, 5)

While reflecting any points across the x-axis with coordinates as (x, y) becomes, (x, -y). i.e sign of y-coordinate changes.

The rule is: (x, y) arrow (x, -y)

If Jodi wants to visit her extended family in Barbados next summer, and the flight costs $450, then she needs to save 50$ each month if she wants to buy the flight in exactly 9 months.

If the flight costs $450, then the amount of money Jodi needs to save each month can be determined by using division.

Division is one of the four basic operations of arithmetic and involves the separation into equal parts.

By dividing the cost of the flight by the number of months, the money Jodi needs to save each month can be calculated.

Considering x to be money Jodi needs to save each month,

x = flight cost / number of months

x = 450 / 9

x = 50
