The equation of the line will be given as y = -4x - (- 17/ 4).

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

Given that:-

The equation of the line will be given as:-

y  -  y₁ = m ( x  -  x₁)

slope m will be calculated as:-

[tex]m =\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{1+1}{\dfrac{-3}{4}+\dfrac{1}{4}}=-4[/tex]

The equation will be:-

y  -  (1/4)  =  -4( x +  1 )

y  = -4x  -  (17/4)

Therefore the equation of the line will be given as y = -4x - (- 17/ 4).

The area of a square is the square of its side. The area of the square is 2.2477 units².

The area of a square is the square of its side. It is given by the formula,

Area of the square = a²

Given the circumference of the circle is 9.42 units. Therefore, the radius of the circle can be written as,

Circumference of the circle = 2πr

[tex]\rm9.42\ units= 2\pi r\\\\r = \dfrac{9.42}{2\pi}\ units[/tex]

Now, as the side of the square is equal to the radius of the circle, therefore, the area of the circle will be equal to,

Area of the circle = a² = r²

[tex]\rm \text{Area of the circle }= (\dfrac{9.42}{2\pi})^2[/tex]

                            [tex]\rm = \times \dfrac{9.42}{2\pi} \times \dfrac{9.42}{2\pi}\\\\ = 2.2477\ units^2[/tex]

Hence, the area of the square is 2.2477 units².

Answer:

Approximately [tex]215[/tex] square units.

Step-by-step explanation:

The area of this figure is equal to:

[tex]\begin{aligned}& \text{Area of figure} \\ =\; & \text{Area of square} \\ &+ \text{Area of circle} \\ &- \text{Area of overlap}\end{aligned}[/tex].

The area of the square is [tex]8^{2} = 64[/tex] square units.

The area of the circle of radius [tex]r = 8[/tex] is [tex]\pi\, r^{2} = 8^{2}\, \pi = 64\, \pi[/tex] square units.

Refer to the diagram attached. In this figure, the overlap between the square and the circle is a sector of radius [tex]r= 8[/tex]. The angle of this sector is [tex]90^{\circ}[/tex]- same as the measure of the interior angle of the square.

The area of this sector would then be:

[tex]\begin{aligned} & \pi\, r^{2} \times \frac{90^{\circ}}{360^{\circ}} = 16\, \pi \end{aligned}[/tex].

Therefore, the area of the figure would be:

[tex]\begin{aligned}& \text{Area of figure} \\ =\; & \text{Area of square} \\ &+ \text{Area of circle} \\ &- \text{Area of overlap} \\ =\; & 64 + 64\, \pi - 16\, \pi \\ \approx\; & 215 \end{aligned}[/tex].

Hypotenuse H we need

Apply Pythagorean theorem

Answer:

6.5 miles far from the bank.

Step-by-step explanation:

→ AC = 3.9 miles (perpendicular)

→ BC = 5.2 miles (base)

→ AB = x (hypotenuse)

By using Pythagoras theorem the length of AB will be,

→ (Hypotenuse)²=(Perpendicular)²+(Base)²

→ AB² = AC² + BC²

→ AB² = (3.9)² + (5.2)²

→ AB² = 15.21 + 27.04

→ AB = √(42.25)

→ [ AB = 6.5 ]

Hence, friend's house is 6.5 miles away.

Step-by-step explanation:

An improper fraction is a fraction that's top number (numerator) is bigger than the bottom number (denominator)

Answer:

10/3

Step-by-step explanation:

Improper fractions are fractions where there is a larger number in the numerator than there is in the denominator. The numerator is the number on the top of the fraction, and the denominator is on the bottom. 10 is on top and it is greater than 3, so it is an improper fraction. Improper fractions can also be simplified. 10/3 can be simplified to 3 1/3.

Step-by-step explanation:

Answer:

d= 6

Step-by-step explanation:

radius r = 2.9921129301276 cm

diameter d = 5.9842258602553 cm

circumference C = 18.8 cm

area A = 28.1258615432 cm2

Diameter of circle is 6cm, if the circumference is 18.8 cm

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

The circumference of a circle is the measure of the boundary or the length of the complete arc of a circle.

The formula to find circumference is

C=2pi r

Given circumference is 18.8 cm, we need to find diameter.

To find diameter first we need to find radius

18.8=2×3.142×r

18.8=6.284r

Divide both sides by 6.284

r=2.99

We know that Diameter is two times of radius

d=2r

d=2×2.99

d=5.98=6

Hence diameter of circle is 6cm, if the circumference is 18.8 cm

Answer:

80 × 30 = 2,400

Step-by-step explanation:

We can easily round 79 up to 80 and round 31 down to 30. This would make our expression 80 × 30, which is much easier to compute. We just take 8 × 3 (which is 24) and add two zeros onto the end of the number. This yields us an answer of 2,400 which is very close to the actual multiplication of 79 × 31 which is 2,449 (only 49 more than our estimation).
