What is 7.8×10^5 hours in days?

Answer:

[tex] -3x^{4} + 3{x}^{3} + 8{x}^{2}- 2x - 5[/tex]

Step-by-step explanation:

To avoid confusion, distribute the negative amongst all terms in the second set of parentheses.

I hope this helps you out alot, and as always, I am joyous to assist anyone at any time.

Based on the calculations, the solution to the expression is [tex]-3x^4+3x^3+8x^2-2x-5[/tex]

The distributive property of multiplication states that when the sum of two (2) or more addends are multiplied by a given numerical value or factor, the same output would be produced as when each addend is multiplied respectively by the numerical value or factor, and the products are added together.

Based on the information provided above, we have this expression:

[tex](-2x^4-2x^3+8x^2+2)-(x^4-5x^3+2x+7)[/tex]

By applying the distributive property of multiplication to the given expression, we would open the parentheses by distributing the negative sign as follows:

[tex]-2x^4-2x^3+8x^2+2-x^4+5x^3-2x-7\\\\-3x^4+3x^3+8x^2-2x-5[/tex]

Enter your answer, in standard form, in the box.

-9x-6y=15

9x-10y=145

Find y first by eliminating the x.

Add the two equations together.

-9x+9x-6y+-10y=15+145

-6y+-10y=15+145

-6y-10y=160

-16y=160

divide both sides by -16 to get +y

-16y/-16=160/-16

y=-10

Use the substitution method to find x

-9x-6y=15

-9x-6(-10)=15

Do the bracket first

-9x+60=15

Move +60 to the other side. Sign changes from +60 to -60.

-9x+60-60=15-60

-9x=-45

Divide both sides by -9

-9x/-9=-45/-9

x=5

The most accurate summary of nationalism in the Middle East during the 1920s is option c: Broken Western promises and conflicting nationalist goals set the nations of the former Ottoman Empire on the path to conflict.

After World War I, the Middle East experienced a surge in nationalist aspirations as the Ottoman Empire collapsed. However, the promises of self-determination made by Western powers, particularly through the Sykes-Picot Agreement and the Balfour Declaration, were largely unfulfilled.

This led to widespread discontent and conflicting nationalist goals, creating tensions and setting the stage for regional conflicts. Additionally, the imposition of artificial borders and the interference of Western powers further fueled nationalist sentiments, contributing to a turbulent period of political, social, and economic unrest in the Middle East during the 1920s.

The failure of Western promises and the clash of nationalist ambitions indeed played a pivotal role in shaping the trajectory of the region.

Answer: If A Point, Ray, Line Segment, or Plane intersects a segment at its midpoint, then it Bisects the segment.

Step-by-step explanation: A segment, ray, line, or plane that is perpendicular to a segment at its midpoint is called a perpendicular bisector. If a point is on the perpendicular bisector of a segment, then it is equidistant from the endpoints of the segment. Point is equidistant from two points if its distance from each point is the same.

The wrong choice can be defined as follows

Therefore, the "Bisects" is the correct choice.

Step-by-step explanation: To find the range of the data set shown here, let’s first go over what range is. The range of a data set is the difference between the greatest number and the least number.

To find the range of the data set shown here, we will need to subtract the least number from the greatest number.

Least number = 2

Greatest number = 15

Greatest number - least number = range

15 - 2 = range

13 = range

Therefore, the range of the data set shown here is 13.

Answer:

15 and 21

Step-by-step explanation:

Given the n th term formula

T = 2n + 5

To find the 5 th and 8 th terms substitute n = 5 and n = 8 into the formula

[tex]T_{5}[/tex] = (2 × 5) + 5 = 10 + 5 = 15

[tex]T_{8}[/tex] = (2 × 8) + 5 = 16 + 5 = 21

Given:

Tn = 2n+5

Substituting the value inside the formula we get,

2(5) + 5 => 10 + 5 => 15

   2.  The Eighth term, i.e., n=8

Substituting the value inside the formula we get,

2(8) + 5 => 16 + 5 => 21

The expression to show how many hours Kyle practices is 2.5t, where t equals the number of hours Grant practices.

If Kyle practices 2.5 times as many hours as Grant does, and we let t represent the number of hours Grant practices, then the expression to show how many hours Kyle practices would simply be 2.5t. This is because we are given the ratio of Kyle's practice time to Grant's practice time, which we can use to express Kyle's practice time in terms of Grant's.

Answer:

depending on the national/ regional legal provisions in favour of the tax contributor where either the work is provided/ the computer was aquired/ placed, repaired/ the repair company has declared fiscal residency the cost ( in hours) could be determined by 0.07 ( 40h)

Final answer:

The expression 0.07(40h) in the equation represents the amount of tax Deborah has to pay. 0.07 stands for the 7% tax rate applied to the cost of repair, which is denoted by 40h.

Explanation:

The student has asked to identify the part of the expression in 0.07(4 0h) + 4 0h, which represents the tax Deborah has to pay for her computer repairs, where h represents the number of hours it takes to repair the computer. In this expression, the tax component is given by 0.07(40h).

The 0.07 represents the 7% tax rate on the cost of repair. The cost of repair, before tax, is represented by the term 40h. When you multiply 40h by 0.07, you are calculating 7% of the repair cost which equates to the tax amount.

The problem:

If h(x)=-7x and h(x)=63, the what is the value of x?

Step-by-step explanation:

h(x)=-7x

You are asked to find x such that h(x)=63.

So you are solving:

h(x)=63 for x:

-7x=63

Divide both sides by -7:

x=63/-7

Simplify:

x=-9

Let's check:

h(x)=-7x

h(-9)=-7(-9)

h(-9)=63

So -9 is the answer.

The value of x in the equation y = 9 + 3x for a given y value can be found by rearranging the equation to x = (y - 9) / 3, and substituting the desired y value.

The subject of this question is determining the value of x in the equation y = 9 + 3x. In this equation, the b term is 9 and the m term is 3, representing the y-intercept and the slope respectively. To find the value of 'x' that gives a specific 'y' value, one must rearrange the equation to solve for 'x': x = (y - 9) / 3. For example, if we wanted the y value to be 15, we would substitute into the equation and find that x = (15 - 9) / 3 = 2

Answer:

-6/5

Step-by-step explanation:

solution;

let,the number be x,

product of twice of x and six = the difference

difference of eleven times x and 6/5

or, (2x×6)=(11×x)-(6/5)

or, 12x = 11x - 6/5

or, 12x - 11x = -6/5

therefore,x =-6/5

Therefore, the number required is (-6/5) whose product of twice a number and six is the same as the difference of eleven times the number and 6/5 .

Answer:the ball is released when t = 0

The ball is 5.2 feet above the ground when it is released

The ball is 5.2 feet in height from the ground and it will hit the ground after 2 seconds.

A certain kind of relationship called a function binds inputs to essentially one output.

The machine will only accept specified inputs, described as the function's domain, and will potentially produce one output for each input.

In other words, the function is a relationship between variables, and the nature of the relationship defines the function for example y = sinx and y = x +6 like that.

Given the function has height with time t

f(x)=-16t² + 32t + 5.2

At the time of release, the value of time t will be 0

So, t = 0

f(x) = 0 + 0 + 5.2 ⇒ f(x) = 5.2 feet

So height is 5.2 feet

Now,

The time taken to cover this height will be

5.2 = 16t² + 32t + 5.2

16t² + 32t = 0

16t(t + 2) = 0

t = 0 and -2

Since if some height exists then time can never be 0 and time also does not exist in negative so consider 2.

Hence "The ball is 5.2 feet in height from the ground and it will hit the ground after 2 seconds.
