Answers

Answer 1

The shaded region has a surface area of 7π.

What is area?

The size of a region on a surface is measured in area. Surface area refers to the area of an open surface or the border of a three-dimensional object, whereas area of a plane region or plane area refers to the area of a form or planar lamina. The total space occupied by a flat (2-D) surface or the form of an item is defined as its area. Draw a square on a sheet of paper using a pencil. It is a two-dimensional figure. The area of the form on the paper is referred to as its Area. Consider your square to be made up of smaller unit squares.

Here,

find the area of the circle with radius =3 cm,

then subtract the areas of the two circles with radius 1 cm

pir^2 = the area of a circle with radius = r

=pi(3)^2 -pi(1)^2 - pi(1)^2

= 9pi -pi-pi

= 9π-2π

= 7π

The area of shaded region is 7π.

Correct steps given below:

Ian missed the step 3 above.

He wrongly added 91 to both sides instead of subtracting, this resulted in wrong solution.

Answer:

See below.

Step-by-step explanation:

The mistake Ian made was incorrectly distributing -(-91).  When multiplying two negative numbers the result is always positive:  [tex]-a \cdot -b=-a(-b)=ab[/tex].

This error meant he added 91 to both sides of the equation in Step 3 of his calculation, when he should subtract 91 from both sides.

Na fazenda Santa Elisa onde a principal atividade a criação de gado cada hectare deve ser ocupado por 20 bois quantos bois podem ser criados no terreno de 70000 m²

Answers

Answer:

140 bois

Step-by-step explanation:

Observe que:

1 hectare = 10000m²

Na Fazenda Santa Elisa, principal atividade da pecuária, cada hectare deve ser ocupado por 20 bois

Isso significa:

10000m² = 20 bois

O número de bois que podem ser criados no local de 70000 m² é calculado como:

10000m² = 20 bois

70000m² = x

Multiplicação cruzada

10000m² × x = 70000m² × 20 bois

x = 70000m² × 20 bois / 10000m²

x = 140 bois

Portanto, 140 bois podem ser criados em um terreno com 70000m².

What are the approximate solutions of 4x2 3 − 12x to the nearest hundredth?

Answers

The approximate solutions are -0.28 and -2.28.

Now, According to the question:

Given, the equation is 4x^2 + 3 = -12x

We have to find the approximate solutions to the equation.

Using quadratic formula,

[tex]x = \frac{-b±\sqrt{b^2-4ac} }{2a}[/tex]

The equation can be written as 4x^2 + 12x + 3 = 0.

Here, a = 4, b = 12, c = 3

x = [tex]\frac{-12±\sqrt{12^2-4(4)(3)} }{2(4)}[/tex]

x = [tex]\frac{-12±\sqrt{144-48} }{8}[/tex]

x = [tex]\frac{-12±\sqrt{96} }{8}[/tex]

x = [tex]\frac{-12±9.8}{8}[/tex]

Now, x = [tex]\frac{-12+9.8}{8} =\frac{-2.2}{8}[/tex] = -0.275

x = [tex]\frac{-12-9.8}{8} =\frac{-21.8}{8}[/tex] = -2.275

Therefore, the approximate solutions are -0.28 and -2.28.

Consider rigid-body physics in a higher or lower dimension than three. How many coordinates are required to specify the location and orientation of a rigid body:If the space is two-dimensional?a. 2b. 3c. 4d. 5

Answers

In two-dimensional space, only two coordinates are required to specify the location and orientation of a rigid body.

In two-dimensional space, a rigid body can only move in two directions (up/down and left/right) and rotate around a single axis. As a result, only two coordinates are needed to specify the location and orientation of a rigid body in two-dimensional space. The two coordinates needed to specify the rigid body's position are the x-coordinate and y-coordinate, which define the position of the body in the plane. The orientation of the rigid body can be determined by determining the angle between the x-axis and the body's orientation, which is referred to as the angle of rotation. The combination of these two coordinates (position and rotation) specify the full state of the rigid body in two-dimensional space.

The distance between a 16 feet long chord and the center of a circle is 15 feet. Compute the diameter of the circle

Answers

The diameter of the circle is 30 feet

To compute the diameter of the circle, we can use the Pythagorean Theorem. The Pythagorean Theorem states that in a right triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

In this case, the hypotenuse is the diameter of the circle, and the other two sides are the radius and the distance between the chord and the center of the circle.

So, we can write the equation:

diameter^2 = radius^2 + (distance between chord and center)^2

We know the radius is half the diameter, so we can substitute that in:

diameter^2 = (diameter/2)^2 + (15)^2

And we can solve for the diameter:

diameter^2 = diameter^2/4 + 225

diameter^2 = diameter^2/4 + 225

4diameter^2 = diameter^2 + 900

3diameter^2 = 900

diameter^2 = 900/3

diameter = sqrt(900/3)

So the diameter of the circle is 30 feet.

Alternate angles are angles that occur on opposite sides of the transversal line.

I have 2 standard, 6-sided dice; one is brown, and the other is black. I roll them both. What is the probability that the sum of the numbers that I roll is less than 4?

Answers

Answer:

1/36

Step-by-step explanation:

Since you have two six-sided die, you have 2 sets of 1-6.

Set 1: 1,2,3,4,5,6

Set 2: 1,2,3,4,5,6

Now, we need to find out how many items in the sets add up to equal a sum less than 4.

1 + 1 = 2

2 + 1 = 3

We can roll a 1 and a 1 with a 1/6 chance each.

We can also roll a 1 and a 2 with a 1/6 chance as well.

So, to get the final probability, we would multiply the two fraction together.

1/6 x 1/6 = 1/36

There is a 1/36 chance that the sum of the numbers you roll will be less than 4.

How do you solve 2x 3y =- 6?

Answers

We can solve this equation using the distributive property. First, we will use the distributive property to multiply the 3y by 2.

What is distributive property?

The distributive property is a mathematical rule that allows you to multiply a single number by a group of numbers by multiplying the single number by each number in the group individually. This rule can be expressed in two ways. The first way is a(b + c) = ab + ac. The second way is a(b - c) = ab - ac.

This will give us 2x * 3y = 2(3y). Then, we will subtract 6 from both sides of the equation, which gives us 2x * 3y - 6 = 2(3y) - 6. We can then divide both sides of the equation by 6, which gives us 2x * 3y / 6 = 2(3y) / 6. Finally, we can divide both sides of the equation by 3y, which gives us 2x = -2. Therefore, the solution to 2x 3y = -6 is 2x = -2.

The areas of the squares adjacent to two sides of a right triangle are shown below.

What is the area of the square adjacent to the third side of the triangle?

Answers

Answer:

11 units^2

Step-by-step explanation:

We know that the area of a square is the side squared, so we can use the inverse of this formula to say the side of a square is the square root of the the area. This gives us√33 and √44 as the side lengths of the red and green squares respectively. Next, we use the pythagorean theorem to find the other side of the white right triangle, which is also a side of the blue square. So:

(√44)^2 - (√33)^2 = side^2

44 - 33 = side

side^2 = 11

side = √11

To find the area of a square, you just square the side, so we get (√11)^2 which is just 11 units^2.

What is seed?

In botany, a seed is an undeveloped plant embryo and food reserve encased in a protective outer covering. In a broader sense, "seed" refers to anything that can be sown, such as seed and husk or tuber.

Seeds are formed when a ripened ovule is fertilised by pollen-derived sperm, resulting in a zygote. The embryo develops from the zygote within a seed, forming a seed coat around the ovule and growing to a certain size within the mother plant before growth stops.

The formation of seeds is a stage in the reproduction of seed plants (spermatophytes). Other plants, such as ferns, mosses, and liverworts, lack seeds and must reproduce exclusively through water.
