first, these are the points on our line:

• (-2, 10) • (4, -8)

what we need at this moment is the gradient (slope) of the line.

remember, there's a little formula that will help us find the gradient:

[tex]\large\text{$\displaystyle\frac{y_2-y_1}{x_2-x_1}$}[/tex]

our values are:

• (-2, 10) and (4, -8)

after substituting the values into the above formula, we obtain

[tex]\large\text{$\displaystyle\frac{-8-10}{4-(-2)}$}[/tex]

after simplifying, we obtain

[tex]\large\text{$\displaystyle\frac{-18}{4+2}$}[/tex]

simplifying more,

[tex]\large\text{$\displaystyle\frac{-18}{6}$}[/tex]

dividing,

[tex]\large\text{$-3$}[/tex]

but that's only part of our problem. we need to find the equation, and we have the gradient only.

let's use the first point in our equation

• (-2, 10)

m is the gradient.

this is what we obtain after substituting the values

[tex]\large\text{$y-10=-3(x-(-2)$}[/tex]

simplifying

[tex]\large\text{$y-10=-3(x+2)$}[/tex]

simplifying more

[tex]\large\text{$y-10=-3x-6$}[/tex]

moving 10 to the right side

[tex]\large\text{$y=-3x-6+10$}[/tex]

and finally

The question is a bit obscure. The best choice I think, would be A. F(x) could equal something like y = x - 3. When y = 0, x = 3 or put the other way, when x = 3 y= 0.

Answer:

91/20 or 4 11/20

Step-by-step explanation:

First, convert the 2 amounts into improper fractions

Red: 21 4/5 = 114/5

Purple: 18 1/4 = 73/4

Then, using cross multiplication, you can give them the same denominator

Red: 114/5 = 456/20

Purple: 73/4 = 365/20

Then just subtract the numerators and keep the denominator

456/20 - 365/20 = 91/20

So your answer is

91/20 or 4 11/20

Answer:

26 cm

Step-by-step explanation:

Formula for Perimeter

Solving (given Perimeter is 84 cm and width is 16 cm)

Answer:

L= 26cm

Step-by-step explanation:

Perimeter= 2(l x w)

Perimeter= 84cm

Width= 16cm

Length=?

84= 2l + 32

2l = 84-32

2l= 52

L= 52/2

L= 26cm

The sum of the first 14 terms of the finite geometric series 0.5+ (-1) +2+... is -2730.5

The series is given as:

0.5+ (-1) +2+...

The above series is a geometric series, with the following parameters:

The sum of the first 14 terms is calculated using:

[tex]S_n= a *(1 - r^n) \div (1 - r)[/tex]

So, we have:

[tex]S_{14}= 0.5 *(1 - (-2)^{14}) \div (1 + 2)[/tex]

Evaluate

[tex]S_{14}= -2730.5[/tex]

Answer:

h(x) = x³ + 4x² - 49x - 196

Step-by-step explanation:

h(x) = (x² - 49)(x + 4) <== distribute

h(x) = x²(x) - 49(x) + x²(4) - 49(4)

h(x) = x³ - 49x + 4x² - 196 <== rewrite in standard form (descending degrees)

Answer:

569 millimetres because 290 +36 ml is 569

To solve this problem, we have to find the area of the semi circles and the area of the rectangle and add them up together.

The area of the field is equal to 8719.36m^2

Let us start by finding the area of the rectangle.

Data;

Area of a rectangle is given as

[tex]a = length * width \\a = 86 * 64\\a = 5504m^2\\[/tex]

The area of the rectangle is 5504m^2

Area of the semicircle

The formula of a semi circle is given as

[tex]A = \frac{1}{2} \pi r^2[/tex]

But since we have two semi circles here, we can simply multiply it by two and the formula becomes

[tex]A = 2 * \frac{1}{2} \pi r^2\\A = \pi r^2[/tex]

But in the question, we have the diameter of the semi circle as the length of the rectangle.

[tex]radius = \frac{diameter}{2} \\radius = \frac{64}{2} \\radius = 32m[/tex]

The radius of the semicircle is 32m

Area of the semicircle is

[tex]A = \pi r^2\\A = 3.14 * 32^2\\A = 3215.36m^2[/tex]

The area of the field is

[tex]area of field = 3215.36 + 5504\\area = 8719.36m^2[/tex]

The area of the field is equal to 8719.36m^2

Answer: Choice A

40.61 square meters

==========================================================

Explanation:

The area of a full circle is

A = pi*r^2

meaning half of it (aka semicircle) will have this area

A = 0.5*pi*r^2

The diameter of the semicircle is 5.4 meters, which divides in half to get the radius of r = 2.7

The semicircle has an area of...

A = 0.5*pi*r^2

A = 0.5*3.14*(2.7)^2

A = 11.4453

which is approximate since pi = 3.14 is approximate.

Now compute the area of the triangle

area = base*height/2 = 5.4*10.8/2 = 29.16

Then add those sub-areas to get the grand total area.

semicircleArea + triangleArea = 11.4453+29.16 = 40.6053

That rounds to 40.61 which shows why choice A is the answer.

Answer:

28 as a fraction would be written as 56/2.

Step-by-step explanation:

The fraction can be written as 7/25.

Explanation:

Given Input Value = 28%

Place the Percentage Value at the top over 100. = 28/100

The given fraction is 28/100.

On reducing the fraction, we get the exact form 28/100. = 7/25

The exact form of the fraction is 7 /25.
