The product of the given expressions is 2x squared + 7x minus 4.

Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.

Given expressions are 2x - 1 and x + 4.

We have to multiply both the expressions.

(2x - 1) (x + 4) = (2x . x) + (-1 . x) + (2x . 4) + (-1 . 4)

                      = 2x² - x + 8x - 4

Adding the like terms together,

The bearing of point X from point Z is 280°

To find the bearing of point X from point Z, we need to use the principle of alternate angles in each point and sum of angles of a triangle

The triangle formed is as follows

angle x = 100 - 65 = 35

angle y = (180 - 140) + 65 = 105

angle z = 180 - angle y + angle x = 180 - 35 + 105 = 40

The bearing of point X from point Z,

= 360 - angle z - alternate angle from y

= 360 - 40 - 40

The best first step to begin to simplify the equation -2(x + 3) = -10​ is:

Dividing both sides of the equation by -2 to get x + 3 = 5

As per the given data, the equation is given by -2(x + 3) = -10

We have to determine the best first step in solving the equation:

-2(x + 3) = -10​

Firstly we start by distributing -2 in the bracket (x + 3)

-2x - 6 = -10

Or

-2(x + 3) = -10​

Also if we divide both sides of the equation by -2, we get

x + 3 = 5

Now, we can easily solve the equation.

Hence, the first best step to begin to simplify the equation -2(x + 3) = -10​ is:

Distributing -2 in the bracket (x+3)

We get -2x -6 = -10

Or Dividing both sides of the equation by -2

The height of his kite on this blustery day if an angle of elevation is 40°, 64.3 meter

An angle is a mathematical term, which we can define, when two straight lines or rays meet at a common endpoint. The common point is called the vertex of an angle. The word angle comes from a Latin word named ‘angulus,’.

Interior angles:- The inner angle made by the intersection of two polygonal sides.

Exterior angles:- The outer angle made by the intersection of two polygonal sides.

Given that,

Edward is flying a kite on a beautiful sunny day at the beach,

An angle of elevation of 40°

kite string let out = 100 meter

The height of his kite = ?

Suppose, height  = h

if we consider horizontal distance of kite from the Edward and Vertical distance from the Edward

It will form a right angle triangle

Now, we can use sine formula in the right angle triangle,

α =  40°

L  = 100 meter

h  = ?

It is known that,

sinα  = height/hypotenuse  

sin40° =  h/100

Step-by-step explanation:

Answer:

0.00000016

Step-by-step explanation:

Raise 0.02 to the power of 4.

0.000000256.

The expression (0.02)^4 represents the fourth power of 0.02. In mathematical terms, "^" symbol is used to indicate exponentiation, so (0.02)^4 is equal to 0.02 multiplied by itself 4 times.

To calculate this expression, we can multiply 0.02 by itself 4 times:

0.02 * 0.02 * 0.02 * 0.02 = (0.02)^4 = 0.000000256

So, the result of (0.02)^4 is approximately equal to 0.000000256.

The probability that a randomly selected person from the city will be a woman is 17,000 / 190,000, or approximately 0.089.

1. Calculate the total number of women: 17,000

2. Calculate the total population of the city: 190,000

3. Divide the number of women by the total population: 17,000 / 190,000

4. The probability is approximately 0.089

The probability that a randomly selected person from the city will be a woman is 17,000 / 190,000, or approximately 0.089.

The probability that a randomly selected person from the city of Akron, Ohio will be a woman is 0.089. This means that out of every 100 people, approximately 8.9 of them will be female.

In this question, we will use the addition rule of the probability to calculate the required probability. The probability is a positive quantity from zero to one inclusively. The negative probability of an event does not exist

This is for independent events

P(A U B): This is A or B or both:

P(A n B): This is A and B.

P(A U B) = P(A) + P(B) - P(A n B)

P( A n B) = P(A) x P(B)

Hence:

A or B but not both:

P(A U B) = P(A) + P(B) - P(A n B) - P(A n B) = P(A) + P(B) - 2 x P(A n B)

A. The circular base of the bucket is larger.

B. The bale has a larger volume.

A. The circular base of the bucket has a larger area than the rectangular base of the bale.

The formula for the area of a circle is π * r^2, where r is the radius. The diameter of the bucket is 3 feet, so the radius is 3/2 feet. The area of the circular base is therefore π * (3/2)^2 = 7.07 square feet.

The rectangular base of the bale has length 2 feet and width 3 feet, so its area is 2 * 3 = 6 square feet.

Since 7.07 > 6, the circular base of the bucket is larger.

B. The bale has a larger volume than the bucket.

The formula for the volume of a rectangular prism is l * w * h, where l is the length, w is the width, and h is the height. The bale has length 2 feet, width 3 feet, and height 5 feet, so its volume is 2 * 3 * 5 = 30 cubic feet.

The formula for the volume of a cylinder is π * r^2 * h, where r is the radius and h is the height. The radius of the bucket is 3/2 feet and the height is 5 feet, so the volume of the bucket is π * (3/2)^2 * 5 = 22.36 cubic feet.

In Mathematics, the point-slope form of a straight line can be calculated by using this mathematical expression:

y - y₁ = m(x - x₁) or y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

Where:

Next, we would determine the linear equation representing the line of f(x) which passes through the points (0, 4) and (4, 0) by using the point-slope form as follows:

y - y₁ = (y₂ - y₁)/(x₂ - x₁)(x - x₁)

The probability of winning the game depends on the type of opponent. If the opponent is of type 1, the probability of winning is 0.3; type 2, 0.4; and type 3, 0.5.

The probability of winning the game depends on the type of opponent. There are three types of opponents: type 1, type 2, and type 3. Against type 1 opponents, the probability of winning is 0.3. Against type 2 opponents, the probability of winning is 0.4. Against type 3 opponents, the probability of winning is 0.5. As the opponent is chosen randomly, the probability of winning is the average of all three probabilities. This means that the probability of winning the game is 0.4. To calculate this, we first add the probabilities of winning against each type of opponent: 0.3 + 0.4 + 0.5 = 1.2. We then divide this result by the number of opponent types (3): 1.2/3 = 0.4. This means that the probability of winning the game is 0.4.
