If the sales tax rate is 9.75 % in California, then how much would you pay in Los Angeles for a pair of shoes that cost $39.00?

Answer: a1=6

               An = An-1 - 4

Step-by-step explanation:

N represent what number in the sequence you choose. So in the equation n-1 would be the umber in the equation subtracting 1 then subtracting the difference. The factor you are multiplying by in this sequence is -4. You find the difference by taking any number in the sequence and dividing it by the previous number in the sequence.

Answer:

1 and 1/4 pounds

Step-by-step explanation:

Answer: y = -12

Equation's:

Solve them simultaneously:

4x - 28 = 1.5x - 18

4x - 1.5x = -18 + 28

2.5x = 10

x = 10/2.5 = 4

Now find the value of y:

y = 4x - 28

insert x = 4

y = 4(4) - 28

y = 16 - 28 = -12

Answer:

[tex]y=-12[/tex]

Step-by-step explanation:

Given system of equations:

[tex]\begin{cases}y = 4x - 28\\y = 1.5x - 18\end{cases}[/tex]

Use the method of substitution to solve for x:

[tex]\begin{aligned}y & = y\\\implies 4x-28 & = 1.5x - 18\\4x-1.5x & = -18+28\\2.5x & = 10\\x & = 10 \div 2.5\\x & = 4\end{aligned}[/tex]

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

[tex]\begin{aligned} y & = 4x-28\\\implies y & =4(4)-28\\y & = 16-28\\y & = -12\end{aligned}[/tex]

For this exercise, the graph of a logarithmic function is shown in the image attached below.

A logarithmic function is a type of function that graphically represents the inverse of an exponential function. Mathematically, a standard logarithmic function is written as [tex]y = log_nx[/tex].

In Mathematics, the domain of any logarithmic function is from (x > 0) to infinity (+∞). Thus, its graph moves to the right on the vertical axis and it increases to infinity (+∞) as the value of x increases.

In this scenario, an image of all the graphs wasn't provided, so, I would proceed to add an attachment to illustrate the graph of a logarithmic function.

Note: The graph (u-shaped) shown in the image attached above is that of a parabolic function.

Answer:

[tex]k(2) = 2[/tex]

[tex]k(3) = 0[/tex]

Step-by-step explanation:

Given:

[tex]\begin{cases}k(1)=4\\k(n)=k(n-1)-2\end{cases}[/tex]

The function [tex]k(n)[/tex] tells us that each term is 2 less than the preceding term.

Therefore:

[tex]\implies k(1)=4[/tex]

[tex]\implies k(2)=k(1)-2=4-2=2[/tex]

[tex]\implies k(3)=k(2)-2=2-2=0[/tex]

[tex]\implies k(4)=k(3)-2=0-2=-2[/tex]

[tex]\implies k(5)=k(4)-2=-2-2=-4[/tex]

[tex]\implies k(6)=k(5)-2=-4-2=-6[/tex]

Rearranging the formula to make the preceding term the subject:

[tex]\begin{aligned} k(n) & = k(n-1) - 2\\\implies k(n)+2 & = k(n-1)\\k(n-1) & =k(n)+2\end{aligned}[/tex]

Therefore:

[tex]\implies k(1)=4[/tex]

[tex]\implies k(0)=k(1)+2=4+2=6[/tex]

[tex]\implies k(-1)=k(0)+2=6+2=8[/tex]

The x-intercept and y-intercept of the equation: 3x - y = -9 is -3 and 9 respectively.

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

We have equation:

3x - y = -9

The above equation represents a linear equation;

The equation can be written as:

y = 3x + 9

To find the x-intercept plug y = 0

x = -3

To find the y-intercept plug x = 0

y = 9

Thus, the x-intercept and y-intercept of the equation: 3x - y = -9 is -3 and 9 respectively.

Answer:

Blue Rectangle: 135 mm²

Not sure if you need this but the Total Square: 225 mm²

Step-by-step explanation:

Area of a rectangle: length x width

Area of a triangle: [tex]\frac{1}{2}[/tex] x base x height

First find the area of the blue rectangle.

Length = 15 mm

Width = 9 mm

Area = 135 mm²

Now find the area of the blue triangle:

Base = 6 mm (because the bottom is 15 total and you subtract the 9)

Height = 15 mm

Area = 45 mm²

Ann and Bob's age is 21 years  and 28 years respectively and after 14 years the ratio will be 5:6.

What is Ratio ?

The comparison of one quantity to other is called a ratio and when two ratios are equal they are said to be in proportion.

It is given in the question that

The ratio of Ann's age to bob's age is 3:4

in 7 years time this ratio will be 4:5

their ages now = ?

Let the age of Ann and Bob is x and y

x:y = 3:4

x =(3/4)y

After seven years

(x+7):(y+7) = 4 :5

(x+7)/(y+7) = 4/5

((3/4)y +7)/(y+7) = 4/5

(3y +28)/(y+7) = 16/5

5*(3y+28)= 16(y+7)

15y +140 = 16y+112

y = 140-112

y =28 years

x = 21 years.

After x years suppose the ratio is 5 :6

(21+x)/(28+x) = 5:6

126 +6x = 140 + 5x

x = 14 years.

Therefore after 14 years the ratio will be 5:6.

Answer:

  54 chickens

Step-by-step explanation:

This problem requires you find the area of Thomas's field, then use that area to find the number of chickens he can keep. The irregularly-shaped field can be considered as composed of shapes that you know how to find the area of.

__

There are many ways the area can be divided. One of them is shown in the attachment. That shows the area to be the sum of the areas of a triangle and a trapezoid.

The triangle has a base of 20 m and a height of 7 m, so an area of ...

  A = 1/2bh

  A = 1/2(20 m)(7 m) = 70 m²

The trapezoid has bases of 11 m and 18 m, and a height of 14 m. Its area is ...

  A = 1/2(b1 +b2)h

  A = 1/2(11 m +18 m)(14 m) = 1/2(29 m)(14 m) = 203 m²

The area of the field is the sum of these areas:

  field area = triangle area + trapezoid area

  field area = 70 m² +203 m² = 273 m²

__

Each chicken requires an area of 5 m², so the total area for n chickens is ...

  area for n chickens = 5n . . . . square meters

This area cannot exceed the area of the field, so an inequality can be written:

  area for n chickens ≤ field area

  5n ≤ 273

  n ≤ 54.6 . . . . . . divide by 5

Thomas can keep a maximum of 54 chickens in the field.
