Answer:

No of these answers has a slope of  [tex]\frac{-3}{5}[/tex] . My guess is B becasue its close to [tex]\frac{-3}{5}[/tex] unless the 5 is supposed to be negative

(4, 0), (-2, 10)   [tex]\frac{10 - 0 }{-2 - 4 }= \frac{10}{6}[/tex] you have to simplfy, the answer will be [tex]\frac{5}{3}[/tex]

(10, -2), (0, 4)  [tex]\frac{4 - -2 }{0- 10 }= \frac{6}{-10}[/tex] you have to simplfy, the answer will be [tex]\frac{3}{-5}[/tex]

 (4, 2), (10, 4)  [tex]\frac{4 - 2 }{10 - 4 }= \frac{2}{6}[/tex] you have to simplfy, the answer will be [tex]\frac{1}{3}[/tex]

What is the radius of the circle?

The radius of the circler is defined as the distance from the centre of the circle to the outermost surface of the circle. The diameter of the circle is the distance between the two points on the surface of a circle passing through the centre of the circle.

Given that the diameter of the circle is 28 millimetres. the radius of the circle is calculated as,

Radius = Diameter / 2

Radius = 24 / 2

Radius = 12 millimetres

Therefore, the radius of the button will be 14 millimetres.

The sum of a geometric series is given by ...

  Sn = a1·(r^n -1)/(r -1)

Here, the first term is 24000, and the growth factor r is 1+4% = 1.04. The sum is then ...

  S5 = 24000·(1.04^5 -1)/(1.04 -1) ≈ 129992

The total earned over 5 years was $129,992.

Write an exponential function to describe the given sequence of numbers, assuming that the first number in the sequence corresponds to x = 0.
5.30, 180, 1080, 6480...

Answers

Answer:

[tex]y = 5(6) {}^{x} [/tex]

Step-by-step explanation:

A exponential function is represented by

[tex]y = ab {}^{x} [/tex]

where a is the vertical stretch and b is the base and x is the nth

power of x

Since the first number corresponds with zero, that means our y intercept is the first number.

This means when x=0 , y=5 so let find the value of 5.

[tex]5 = ab {}^{0} [/tex]

b to the 0th power equal 1 so

[tex]5 = a \times 1[/tex]

[tex]a = 5[/tex]

Our equation is for now

[tex]y = 5b {}^{x} [/tex]

Now let plug in 1,30

[tex]30 = 5b {}^{1} [/tex]

Divide 5 by both sides

[tex]6 = b {}^{1} [/tex]

Anything to the 1st power is itself so b equal 6.

So our equation is

[tex]y = 5(6) {}^{x} [/tex]

5) 3(x - 9) = 3x - 27. So, 5) also dosn't apply.

Step-by-step explanation:

1) 9(x - 3) = 9x - 27. So, 1) applies.

2) 3(3x - 9) = 9x - 27. So, 2) applies.

3) x(9x - 3) = 9[tex]x^{2}[/tex] - 3x. So, 3) dosn't apply.

4) 3(3x - 7) = 9x - 21. S0, 4) dosn't apply.

5) 3(x - 9) = 3x - 27. So, 5) also dosn't apply.

The expressions that are equivalent to 9x - 27 are:

9(x - 3)

3(3x - 9)

To determine which expressions are equivalent to 9x - 27, let's simplify each of the given options:

9(x - 3):

Expanding the expression, we get 9x - 27.

This expression is equivalent to 9x - 27.

3(3x - 9):

Expanding the expression, we get 9x - 27.

This expression is equivalent to 9x - 27.

x(9x - 3):

Expanding the expression, we get 9x² - 3x.

This expression is NOT equivalent to 9x - 27.

3(3x - 7):

Expanding the expression, we get 9x - 21.

This expression is NOT equivalent to 9x - 27.

3(x - 9):

Expanding the expression, we get 3x - 27.

This expression is NOT equivalent to 9x - 27.

Therefore, the expressions that are equivalent to 9x - 27 are:

9(x - 3)

3(3x - 9)

The ABC Book Club charges a $40 monthly fee, plus $2 per book read in that month. The Easy Book Club charges a 35$ monthly fee, plus 3$ per book read in that month. For each club, how many books must be read in 1 month for the total charges from each club to be equal.

Answers

The expression for the cost of the ABC Book Club is 2x + 40. The expression for the cost of the Easy Book Club is 3x + 35. To find when the total charge for both book clubs is equal, the two expressions must equal each other. (x = the number of books read)

2x + 40 = 3x + 35

Subtract 35 from both sides.

2x + 5 = 3x

Subtract 2x from both sides.

5 = x

So, the total charge for each club is equal when 5 books are read.

Find the area of the shape below giving your answer to 1 decimal place.

Answers

Answer:

198.5 cm²

Step-by-step explanation:

From the figure above we can treat the two semi circles as 1 circle.

Now, the diameter is 10 cm

Thus;

Radius; r = 10/2

r = 5cm

Now, formula for area of a circle is;

A = πr²

Thus;

Area of 2 semi circles = Area of 1 circle = π × 5²

A_circle = 78.54 ≈ 78.5 cm²

When we take out the 2 semi circles, what we have left is a rectangle.

Now, the length of the rectangle will be;

Length; L = 22 - 5 - 5 = 12 cm

*This is because the radius of the semi circle is 5 and distance from the edge of the 22 cm length to the centre of the semi circle is 5 cm

Thus, area of rectangle is given by;

A_rect = LW

W in the image is 10 cm

Thus;

A_rect = 12 × 10

Total area of shape is;

A_total = 120 + 78.5

A_total = 198.5 cm²

What is the slope of a line that passes through the origin and the point (6, 3)

Step-by-step explanation:

Formula for getting slope using 2 points...

(y2 - y1) / (x2 - x1)

= (3 - 0) / (6 - 0)

= 3 / 6

= 1/2

So...

Slope is 1/2

Hope this helps :)

Let me know if there are any mistakes!!

Answer:  The slope is   1/2

Step-by-step explanation:

When a line passes through the origin the equation of the line will be represented in the form    y= kx   where k is the slope.

To to find k you will need to divide both sides by x.

y = kx

y/x = kx/x

  k = y/x  

This means that to find k, you will need to divide the y coordinate of the point by the x coordinate.  

  k = 3/6

K = 1/2
