Step-by-step explanation:

The values of the unknown variables a,b,c,d,e and f is 8, 7, -3, 6, 1, and 2 respectively.

The code is 2 ( 7 + 6 ) + 8 ( 1 - ( - 3 ) ).

1.given that

[tex] x^4 . x^a = {x}^{12}[/tex]

we know the formula

[tex] a^m . a^n = {a}^{m+n}[/tex]

so, [tex] {x}^{(4+a)} = {x}^{12}[/tex]

if bases are equal then Powers will be equals.

then 4 + a = 12

a = 12 - 4

a = 8.

2. given that.

[tex] (y^b)/(y^5)= y^2[/tex]

we know the formula

[tex] a^m/a^n = {a}^{(m-n)}[/tex]

so, [tex] {y}^{(b-5)} = y^2[/tex]

when bases are equal then Powers will be equal.

b - 5 = 2

b = 2 + 5

b = 7

3.given that

[tex] 3^c = (1)/(27)[/tex]

so, [tex] 3^c = ( 1/3)^3 [/tex]

[tex] 3^c = {( 3/1)}^{-3} [/tex]

if bases are equal then Powers will be equals.

then c = -3.

4.given that

[tex] (m^3)^2 = m^d[/tex]

we know the formula

[tex] (a^m)^n = {a}^{m.n}[/tex]

[tex] m^6 = m^d[/tex]

if bases are equal then Powers will be equals.

then d = 6

5. given that

[tex] 7^0 = e[/tex]

e = 1

6. given that

[tex] {4}^{(-2) }. {4}^{9}. {4}^{(-5)} = 4^f[/tex]

we know the formula

[tex] a^m . a^n = {a}^{(m+n)}[/tex]

so, [tex] {4}^{(-2+9-5)} = 4^f[/tex]

if bases are equal then Powers will be equals.

then -7+9 = f

f = 2.

Hence, the values of the unknown variables a,b,c,d,e and f is 8, 7, -3, 6, 1, and 2 respectively.

The code is

f ( b + d ) + a ( e - c )

I don't know if the last one is correct

Step-by-step explanation:

the line is perpendicular to

y = 2x.

and it goes through the point (1, 2).

the point-slope form looks like

y - y1 = a(x - x1)

"a"being the slope, and (x1, y1) being a point on the line.

the slope-intercept form is

y = ax + b

"a" is again the slope, "b" is the y-intercept (the y value when x = 0).

as you can see, we need the slope of the new line in both cases.

then we will start with the point-slope form, and transform it into the slope-intercept form.

the slope of a line is generally the ratio (y coordinate change / x coordinate change) when going from one point on the line to another.

it is always the factor of x.

we can see it is 2 for the original line. that means 2/1.

a perpendicular slope is turning the x and y values upside down, and is flipping the sign.

so, in our case it is

-1/2

so, starting with the new slope and the point to create the point-slope form :

y - 2 = -1/2 × (x - 1)

and from there we transform into the slope-intercept form :

2y - 4 = -x + 1

2y = -x + 5

y = (-x + 5)/2 = -1/2 x + 5/2 = -1/2 × (x - 5)

all of the expressions in the last line are valid forms to write it.

Answer:

Step-by-step explanation:

Point slope form y-y₁ = m(x-x₁)

-5 - (-6) = m(9 - 1)

1 = m(8)

1/8 = m

y= 1/8x + b

-6 = 1/8(1) + b

b = -6.125

y = 1/8x -6.125

By solving inequality  [tex]x[/tex] ∈ [tex][-2,3)[/tex]

What is inequality?

A declaration of the relation in terms of greater, greater than or equal to, smaller, or less than or equal to between two numbers or algebraic expressions is known as inequality.

[tex]4\leq 3x+10 < 19[/tex]

Rearranging the above equation

[tex]\left \{ {{4\leq 3x+10} \atop {3x+10} < 19} \right.[/tex]

Subtracting 10 from the above equation

[tex]\left \{ {{4-10\leq 3x+10-10} \atop {3x+10-10 < 19-10}} \right[/tex]

[tex]\left \{ {{-6\leq 3x} \atop {3x < 9}} \right.[/tex]

Dividing the above equation by 3

[tex]\left \{ {{\frac{-6}{3}\leq \frac{3x}{3} } \atop {\frac{3x}{3} < \frac{3}{3} }} \right.[/tex]

[tex]\left \{ {{-2\leq x} \atop {x < 3}} \right[/tex]

The amount of the 1167 rupees he have to pay every month according to the interest rate.

According to the statement

We have to find that the monthly repayments.

So, For this purpose, we know that the

Interest rate is the annual rate that is charged for borrowing , expressed as a single percentage number that represents the actual yearly cost of funds over the term of a loan.

From the given information:

A couple buys furniture for R50 000. They put down a cash deposit of 20% and pay off the balance using a higher purchase agreement, over 4years. The institution charges interest of 10% p.a and monthly Insurance fee of R75.00.

Then

A couple buys furniture =  50,000

cash deposit of 20% = 20% of 50,000

cash deposit = 20/100*50,000

cash deposit = 0.2*50,000

cash deposit = 10000

Left money on which company put interest of 10% =50000 - 10,000

Left money on which company put interest of 10% = 40,000

Then

interest amount per year = 10% of  40,000

interest amount per year = 10/100*40,000

interest amount per year = 0.1*40,000

interest amount per year = 4000

It means interest paid by the customer in 4 years = 4000*4

It means interest paid by the customer in 4 years = 16000

Then

Total money he pays with interest rate in 4 years = 16000 +40,000

Total money he pays with interest rate = 56000

Then

The money he have to pay every month in 4 years = 56000/48

The money he have to pay every month in 4 years = 1167.

So, The amount of the 1167 rupees he have to pay every month according to the interest rate.

Answer: K=6 is correct

Step-by-step explanation:

If you substitute 6 for k and then multiply -7 the answer equals correctly!

The answers are given below:-

a) The exponential function is: [tex]y(t) = 500e^{-0.0117593}[/tex]

b) The rule is: [tex]y(t) = y(0)(\dfrac{358}{500})^{\frac{t}{8}[/tex]

c) The half-life of the element is of 16.599 days.

The mathematical expression  [tex]f(x) = e^x[/tex] denotes the exponential function. The phrase typically refers to the positive-valued function of a real variable, unless otherwise specified.

Following t days, the substance's amount's exponential function is given by:

[tex]y(t) = y(0)e^{-kt}[/tex]

For this problem, we have that:

y(0) = 500, y(8) = 358.

Hence we can solve for k as follows:

[tex]y(t) = y(0)e^{-kt}[/tex]

[tex]358=500e^{-8k}[/tex]

[tex]e^{-8k}=\dfrac{358}{500}[/tex]

[tex]lne^-8k}=ln0.716[/tex]

-8k = ln(0.716)

k = -ln(0.716)/8

k = 0.041759389.

Hence:

[tex]y(t) = 500e^{-0.0117593}[/tex]

For item b, 358/500 of the material is what is left over after each 8-day period, therefore f(t) = t/8, and the rule is as follows:

[tex]y(t) = y(0)(\dfrac{358}{500})^{\frac{t}{8}[/tex]

For item c, using the rule from item a, we have to find t for which y(t) = 0.5y(0), hence:

[tex]y(t) = y(0)e^{-0.0117593}[/tex]

[tex]0.5y(0)=y(0)e^{-0.0117593[/tex]

[tex]e^{-0.0117593}=0.5[/tex]

[tex]lne^{-0.0117593}=ln0.5[/tex]

-0.041759389t = ln(0.5)

t = -ln(0.5)/0.041759389

t = 16.599.

The half-life of the element is of 16.599 days.

The height of the tank is h = 216/s^2, the surface area is s^2 + 864/s and the value of s is ∛432

The given parameters are

Volume = 216

Base length = s

Height = h

The base shape is a square.

So, we have

Volume = s^2h

This gives

216 = s^2h

Divide through by s^2

h = 216/s^2

Hence, the height of the tank is h = 216/s^2

This is calculated as

A = s^2 + 4sh

So, we have

A = s^2 + 4 * s * 216/s^2

Evaluate

A = s^2 + 4 * s * 216/s^2

This gives

A = s^2 + 864/s

Here, we have

A = s^2 + 864/s

Differentiate

A' = 2s - 864/s^2

Set to 0

2s - 864/s^2 = 0

Divide through by s

2 - 864/s^3 = 0

So, we have

864/s^3 = 2

This gives

2s^3 = 864

Divide by 2

s^3 = 432

Take the cube root

s = ∛432

Hence, the value of s is ∛432

option B. g(x)=-2, x<-2, option D. g(x)=-2x+6, x>1 and option E. g(x)=x/2+1 represent a piece of the function in given graph.

The graph of a function is a collection of all ordered pairs of the relation. These are usually represented as points in a Cartesian coordinate system. It is a relationship between an independent variable and a dependent variable. The graph of a function f is the set of all points in the plane of the form (x, f(x)). We could also define the graph of f to be the graph of the equation y = f(x).

Reasons are given below:

In first option that is g(x)=-2x, -2<x<0, we can see a negative sign which indicates that the graph should be downward (negative slope). Also, g(x)=-2x has no y-intercept therefore g(x)=-2x, -2<x<0 does not represent a piece of the function in given graph.

In second option that is g(x)=-2, x<-2, we can see a negative sign and no y-intercept which indicates that it is a horizontal line parallel to x-axis. Also given that x is less than -2, therefore the line should move away from y-axis to the left where lies more negative values. The given data matches the slope given in third quadrant. Hence, it represents a piece of function in given graph.

In third option that g(x)=x-2, -2<x<1, we can see that the function indicates that it has y-intercept at y=-2 and a slope of value 1(positive) which means it should move in upward direction and must cut y-axis at y=-2. The given data does not match with the graph given. Hence, it does not represent a piece of function in the given graph.

In fourth option that is g(x)=-2x+6, x>1, we can see negative sign therefore it should be downward and +6 indicates that it is  with y-intercept too. Hence the given data matches with the graph given and therefore it represents a piece of the function in the given graph.

In fifth option that is g(x)=x/2+1, -2<x<1. As we can see, x lies between -2 and 1, to understand let us assume x=2 then x/2=2/2=1. Therefore, the slope can start at x=1 and extend till -2. Hence, it represents a piece of the function in the given graph.

Therefore, Functions g(x)=-2, x<-2, g(x)=-2x+6, x>1 and g(x)=x/2+1 represent a piece of the function in the given graph.
