Eight subtracted from the product of 4 and a number is less than 26. Translate the sentence into an inequality

The square of the expression 1/2 is given as the numeric value in the terms of the 0.7071.

The value that a number yields when multiplied by itself is known as the square root of the number. The square root is denoted by the radical sign. For example, 16 minus 4 is 16. The root symbol or radicals is another name for the radical symbol. If an integer is a perfect square, we can quickly determine its square root.

square root of the 1/2 = √1/2

We can use this rule for radicals to write the expression.

√a/b = √a/√b

So, by multiplying by the right form of 1, we may rationalise the denominator or, in other words, remove the radical from the denominator:

√1/2 x √2/√2

√2/2

1.4142/2

0.7071

So the square of the 1/2 is 0.7071.

The probability that exactly 12 of the 15 adult smartphone users use their smartphones in meetings or classes is approximately 0.0040 (rounded to four decimal places).

We can solve this problem using the binomial probability formula:

[tex]P(X = k) = (n choose k) * p^k * (1 - p)^(n - k)[/tex]

where:

P(X = k) is the probability of exactly k successes (using smartphones in meetings or classes)

n is the total number of trials (in this case, 15 adult smartphone users)

k is the number of successes (in this case, 12 adults using their smartphones in meetings or classes)

p is the probability of a success on a single trial (in this case, 0.44)

(1 - p) is the probability of a failure on a single trial (in this case, 0.56)

Using this formula, we can plug in the values and calculate:

[tex]P(X = 12) = (15 choose 12) * 0.44^12 * 0.56^(15-12)[/tex]

[tex]= 455 * 0.0001473577 * 0.215872256[/tex]

The polynomial f(x) of degree 4 that has the following zeros 3 (multiplicity 2), -2, 0 is f(x) = (x-3)^2 * (x+2) * (x-0).

To find the polynomial f(x), we can use the fact that the zeros of a polynomial are the values of x that make the polynomial equal to zero. In other words, if a polynomial f(x) has zeros at x=a, x=b, and x=c, then f(x) = (x-a) * (x-b) * (x-c).

In this case, we have zeros at x=3 (with multiplicity 2), x=-2, and x=0. This means that our polynomial will have factors of (x-3)^2, (x+2), and (x-0).

Multiplying these factors together gives us the polynomial f(x) = (x-3)^2 * (x+2) * (x-0), which simplifies to f(x) = (x^2 - 6x + 9) * (x+2) * x. Expanding this expression gives us the polynomial f(x) = x^4 - 4x^3 - 3x^2 + 12x.

Therefore, the polynomial f(x) of degree 4 that has the following zeros 3 (multiplicity 2), -2, 0 is f(x) = x^4 - 4x^3 - 3x^2 + 12x.

The length of 175 metres and width of 87.5 metres will maximise the area 15312.5 square metres.

We have been given that Farmer Ed has 350 metres of fencing and wants to enclose a rectangle mat plot that borders on a river. Farmer Ed does not fence the side along the river.  

First of all we will make a relevant figure to represent the perimeter of fencing for 3 sides as shown in the attachment.

Since Ed will not fence the side along the river, fencing is needed for 3 sides and the perimeter of the fencing would be x + x + y = 2x + y.

Now we will equate perimeter with 350 as: 2x + y = 350

y=350-2x

We know that the area of the rectangle is width times length.

A = X•Y

Upon substituting the value of y in area equation, we will get:

A = x•(350-2x)

A(x) = 350x -2x²

Now we will find derivative of area function as:

A'(x) = d(350- 2)/dx

A'(x) = 350-4x

Now we will equate derivative with 0 and solve for x as:

0 = 350-4

4x = 350

x = 350/4 - 87.5

Upon substituting x = 87.5 in equation y = 350-2x, we will get:

y = 350 - 2x

 = 350 - 2(87.5)

 = 350-175

y = 175

Therefore, the length of 175 metres and width of 87.5 metres will maximise the area.

on substituting x = 87.5 in area function, we will get:

A(87.5) = 350(87.5)-2(87.5)²

A(87.5) = 30625-2(7656.25)

A(87.5) = 30625-15312.5

A(87.5)= 15312.5

Therefore, the largest possible area enclosed would be 15312.5 square metres.

The vertex form of the quadratic equation g is:

g(x) = 25*(x - 4)²

We start with the parent quadratic function:

f(x) = x²

We know that first we apply a translation of 4 units to the right, so we will get:

g(x) = f(x - 4)

And then we compress it horizontally by a factor of 5, then we can write:

g(x) =f( 5(x - 4))

Replacing the actual function we will get:

g(x) = ( 5*(x - 4))²

Distributing the exponent we will get:

g(x) = 5² *(x - 4)²

g(x) = 25*(x - 4)²

Step-by-step explanation:

all pairs of corresponding sides have the same scale factor.

so, we only need to find one to know it for all.

a)

we know 2 corresponding sides : 6 and 12.

that means

12 × s = 6

s = 6/12 = 1/2

b)

x = 5 × s = 5 × 1/2 = 2.5 = 2 1/2

y = 13 × s = 13 × 1/2 = 6.5 = 6 1/2

c)

to be right-angled triangles they need to fulfill the Pythagoras criteria :

c² = a² + b²

c is the Hypotenuse (the side opposite of the 90° angle).

a and b are the legs.

so, for the larger triangle we have

13² = 12² + 5²

169 = 144 + 25 = 169

correct. it is right-angled.

for the smaller triangle :

6.5² = 6² + 2.5²

If she is working at a constant rate, 12 rows had been completed before Elena started working.

To determine the number of rows that were completed before Elena started working, we need to find the equation of the line that represents the relationship between the number of rows completed and the time taken.

We can use the two given points (14, 19) and (20, 22) to find the slope of the line:

slope = (change in rows) / (change in time) = (22 - 19) / (20 - 14) = 3 / 6 = 1/2

Next, we can use the slope and one of the points to find the y-intercept of the line using the point-slope form of a line:

y - 19 = (1/2)(x - 14)

y - 19 = (1/2)x - 7

y = (1/2)x + 12

Now that we have the equation of the line, we can use it to find the number of rows completed when x (time) is equal to 0, which represents the point when Elena started working:

y = (1/2)(0) + 12 = 12

You want the measures of angles d° and e° in the given figure.

Usually, geometry problems tell you not to assume anything that isn't marked or stated regarding the figure. In order to answer this question, we need to assume ...

The base angles in an isosceles triangle are congruent. That means each of them is the complement of half the vertex angle.

  ∠D = 90° -1/2∠A = 90° -8°/2 = 86°

The segments CD and BE are parallel, so angle E is the supplement of angle D:

  ∠E = 180° -86° = 94°

The angle measures are d° = 86° and e° = 94°.

__

Additional comment

This is not a "word problem." All of the relations necessary for answering the question are shown in the diagram, not stated in words. (The question is necessarily written in words—for any problem.)

If b is a base angle and v is the vertex angle of an isosceles triangle, then the sum of angles is ...

  b + b + v = 180°

  2b = 180° -v . . . . . . subtract v

  b = 90° -v/2 . . . . . . divide by 2

Effectively, the altitude of an isosceles triangle bisects the vertex angle and creates two congruent right triangles. The acute angles in that triangle are the original base angle and half the vertex angle. They are complementary.

The net force acting on each ball can be ranked from largest to smallest as Fd>Fb>Fc=Fa, with Fd being the largest  number of force due to its the highest mass and Fa being the smallest force due to its lowest mass.

The net force acting on each ball is equal to the product of its mass and acceleration due to gravity (F=ma). Since all of the balls have the same acceleration due to gravity, the magnitude of the net force on each ball can be determined by its mass. Therefore, the net force acting on each ball can be ranked from largest number to smallest as follows: Fd>Fb>Fc=Fa.

The new average salary of the people on the bus is $84,44,96,111.11  and the median salary will not change and will remain same.

Given, we know that average salary of the 9 people on the bus is $65,000.

Formula for Average = sum of salary of all people/ the number of people.

Let us say average salary of first 8 people is 'S'. Given, salary of the 9th guy on the bus is $120,000 Now, we can write it like this :

⇒$65,000  = (S + $120,000)/9

⇒585,000 = S + $120,000

⇒S = $465,000

Therefore, average salary of 8 people is $465,000 after the 9th guy gets off. Now Bill Gates enters the bus with a salary of $7,600,000,000. New average salary :

⇒ (S + $7,600,000,000) / 9

⇒$84,44,96,111.11

Median will not change since, The median of a set of numbers is the number in the middle when you list them in order. For example, the median of {1, 3, 6, 9, 13} is 6. If you replace the highest number with a different number, the median will not change. In this example, {1, 3, 6, 9, 100} still has a median of 6.

Step-by-step explanation:

A function to represent the total charges for your hotel and car rental is Option C.

In mathematics, a function is a relation between two sets of values, where each input value from the first set (called the domain) corresponds to exactly one output value in the second set (called the range). The output value of a function is determined by its input value and any relevant rules or formulas.

Formally, a function can be defined as follows: Let X and Y be two non-empty sets. A function f from X to Y is a rule or formula that assigns to each element x in X a unique element y in Y, denoted by f(x), such that for any two elements x1 and x2 in X, if x1 = x2, then f(x1) = f(x2). The set X is called the domain of the function, and the set Y is called the codomain or range of the function.

Functions can be represented graphically, algebraically, or in tabular form. The graph of a function shows how the output value of the function varies with the input value, and can be used to visualize the behavior of the function. The algebraic representation of a function can be given by a formula or equation that expresses the output value in terms of the input value. A tabular representation of a function shows the input-output pairs in a table.

Functions are used in many areas of mathematics, science, engineering, and economics to model and describe relationships between variables. They are also used in practical applications, such as in computer programming, where they are used to define algorithms and data structures.

The total charges for the hotel and car rental can be found by adding the charges for the hotel and the car rental. Therefore, the function that represents the total charges can be found by adding the two given functions:

p(x) = 135x + (45 + 79x)

p(x) = 135x + 45 + 79x

p(x) = 214x + 45

Therefore, the function that represents the total charges for the hotel and car rental is p(x) = 214x + 45.
