(5h3−8h)+(−2h3−h2−2h)

Answers

Answer 1

(5h^3 − 8h) + (−2h^3 − h^2 − 2h)
= 5h^3 - 8h - 2h^3 - h^2 - 2h
= 3h^3 - h^2 - 10h

Answer 2

(5h^3-8h)+(-2h^3-h^2-2h)

First, you would distribute into parentheses but there is nothing

5h^3-8h-2h^3-h^2-2h

Now, separate all into common terms

(5h^3-2h^3)(h^2)(-8h-2h)

Now simplify

3h^3h^2-10h

1. AB = 7 units

2.AB= (-0.5, 2)
CD= (-4,-2.5)
EF=(2.5,-3)
3.AB=0
CD=undefined
EF=-4/3

Answer:

1) AB=7 CD=3 EF=[tex]3\sqrt{5}[/tex] 2) [tex]M_{AB}=\frac{-1}{2},2[/tex] [tex] \\ M_{EF} =(\frac{5}{2}-3)[/tex] \\ [tex] \\ M_{EF} =(\frac{5}{2}-3)[/tex] 3) AB not inclined CD not inclined EF 6/5

Step-by-step explanation:

1) We can use the Distance Formula to answer the 1st. question.

But in the first case AB I'd rather doing it intuitively because it is a straight line parallel to the x-axis

A(-4,2) and B(3,2)

In this segment, also parallel we can calculate the length as |-4|+|3|=7 since both have the same y coordinate.

Using the Distance formula to check it:

[tex]D=\sqrt{(3--4)^{2}+(2-2)^{2}}\\D=\sqrt{49}\\D=7[/tex]

C(-4,-1) D(-4,-4)

Similar to the first one but this time with different y coordinates.

The length will be calculated by subtracting the absolute values for y:

|-4|-|-1|=4-1 = 3

Using the Distance formula to check it:

[tex]D=\sqrt{(-4--1)^{2}+(-4--4)^{2}}\\D=\sqrt{9}\\D=3[/tex]

E (1,-1) F(4,-5)

In this case there's no straight line.

So right to the Distance Formula:

[tex]D=\sqrt{(-5-1)^{2}+(4-1)^{2}}\\ D=\sqrt{36+9}\\D=\sqrt{45}\\D=3\sqrt{5}[/tex]

2) To find the Midpoints we need to calculate the Mean of these two points.

A(-4,2) and B(3,2)

[tex]M_{AB} =\frac{-4+3}{2},\frac{2+2}{2}\\M_{AB}=\frac{-1}{2},2[/tex]

C(-4,-1) D(-4,-4)

[tex]M_{CD} =\frac{-4-4}{2} ,\frac{-1-4}{2} \\M_{CD} =(0,\frac{-5}{2})[/tex]

E (1,-1) F(4,-5)

[tex]M_{EF} =\frac{4+1}{2} ,\frac{-1-5}{2} \\ M_{EF} =(\frac{5}{2}-3)[/tex]

3) To find the Slope let's calculate the quotient of a difference between y-coordinates over x-coordinates of two given points.

[tex]m_{AB}=\frac{2-2}{3--4}=\frac{0}{7}=0[/tex]

AB is not inclined.

C(-4,-1) D(-4,-4)

[tex]m_{CD}=\frac{-4--1}{-4--4}=\frac{-3}{-4+4}=\frac{-3}{0}[/tex]

Not Defined for all Real Set of Numbers

The line CD is not inclined.

E(1,-1) F(4,-5)

[tex]m_{EF}=\frac{-5-1}{4--1}=\frac{6}{5}[/tex]

The line EF has a slope of 6/5

The length of a side of an equilateral triangle is 12. find the length of the altitude

Answers

Final answer:

To calculate the altitude of an equilateral triangle with side length 12, divide the side by 2 and multiply by [tex]$\sqrt{3}$[/tex] giving an altitude of approximately 10.3923 units.

Explanation:

To find the length of the altitude of an equilateral triangle with a side length of 12, you can use the Pythagorean theorem. The altitude of the equilateral triangle creates two 30-60-90 right triangles. The altitude is the longer leg in this case, and the side of the triangle is the hypotenuse. In a 30-60-90 triangle, the longer leg (altitude) is [tex]$\sqrt{3}$[/tex]times the shorter leg (half of the side of the triangle).

First, divide the side of 12 into two to get the shorter leg of the right triangle, which is 6. Then, multiply 6 by $\sqrt{3}$ to find the length of the altitude. This results in:

[tex]$6 \times \sqrt{3} = 6\sqrt{3} \approx 10.3923$[/tex]

Therefore, the altitude of the equilateral triangle is approximately 10.3923 units long.

A student earned 37 out of 50 points on the last test. What percent correct did the student earn?

Answers

percent = part / whole * 100

% correct = 37/50 * 100 = 74%

The answer is: " 74% " .
_____________________
% = percent = parts per 100 = x/ 100 ;

37/50 = x/100 ;

Looking at the denominators;

50 * (what value?) = 100 ?

→ 100 ÷ 50 = 2 ;

So; 50 * 2 = 100 ;

So; 37/50 = (37*2) / (50*2) = 74/100 = 74 % .

B.–5 and –1
C.–1 and 4
D.0 and 4

Answers

C -1 and 4 i just did the test on this

Answer

C.–1 and 4

Explanation

Solving the equations y = –x² + 4x and y = x – 4

–x² + 4x = x – 4

x² - 4x + x = 4

x² - 3x = 4

x² - 3x + (3/2)² = 4 + (3/2)²

(x - 3/2)² = 4 + 9/4

= 6.25

x - 3/2 = √6.25 or x - 3/2 = -√6.25

x = 2.5 + 1.5 x = -2.5 + 1.5

= 4 = -1

A patchwork blanket is made up of 10 identical squares.Liam has made 14 squares,Raj has made 12 squares and Gemma has made 15 squares.How many patchwork blankets have they made between them ?

they will make 4 blankets, because when you add the patchwork squares they have made 41 patchwork squares, so 41 divided by 10 is 4, with one left over

They can make one each so in total three blankets because each one can only make one. This is because they all make patches and assuming that they all make them identical in their own piles then they would only be able to make 3 with some left over from each

Answers

Hi!

So I'll show you how to divide the polynomial step-by-step

First you want to write this out like any long division problem.

After that you need to see what times x is x^2?

x*x is x^2 so you want to write x over -6x, you have to make sure that you write it over the same degree term.

Now you multiply both x and 2 (which came from the x +2) by x (which was what you wrote in your first part of the quotient)

Then you subtract what you got from multiplying the x and 2 by x (you should have gotten -8x)

Now you want to bring down the next term in the dividend.

So you want to see what times x is -8x? (This should be -8)

Now you write -8 in the quotient. Now your quotient should be x-8.

After that, you want to multiply x+2 by the -8 and subtract again. (you should get -4)

Since you've filled in the last space in your quotient you have a remainder of -4. Remember to write the remainder as a fraction, -4/x+2

Hope this helped! Let me know if you still have any questions!

The value of the decimal number 4.624 to the nearest 10 places is 4.6

What is rounding off the numbers?

When a number is rounded off, its value is maintained but is brought closer to the next number, simplifying the number. For entire numbers as well as decimals at different places of hundreds, tens, tenths, etc., it is done.

A number can be rounded off to its lower value if the number after the decimal is between 0 and 4. The number will be rounded off to its higher value if the number after it is between 5 and 9.

Given decimal number is 4.624. The rounding off is:-

4.624 = 4.6 at 10 places

Therefore, the value of the decimal number 4.624 to the nearest 10 places is 4.6

What do you do if you're looking for least common multiple and all your numbers are prime?

Answers

It’s important to remember the distinction between “greatest common factor” and “least common multiple.” A factor of a particular number is a bit like a multiplicative LEGO piece that makes it up; they’re the numbers that other natural numbers can be broken down into by division. A multiple is the opposite; a number and the number that it’s multiplied by (say, 8 x 5) *become factors* of a new number (40, in this case).

When we talk about finding the “least common multiple” of a set of numbers, what we’re asking is this: if you list out multiples of each number, what’s the *first* number in those lists they all have in common? For instance, if we wanted to find the least common multiple between 3 and 5, we could list out their multiples:

3, 6, 9, 12, 15, 18, 21
5, 10, 15, 20, 25, 30

15 is the first multiple that appears in both lists, so the least common multiple of 3 and 5 is 15.

Problem page a light bulb consumes 2400 watt-hours per day. how many watt-hours does it consume in 3 days and 6 hours?

Answers

Calculate for 3 days: 2,400 x 3 = 7,200

Calculate 1 day per hour: 2,400 ÷ 24 = 100
Calculate for 6 hours: 100 x 6 = 600

7,200 + 600 = 7,800 watt-hours

Final answer:

The light bulb consumes 7800 watt-hours in 3 days and 6 hours, calculated by summing the daily consumption over three days and additional energy consumed in 6 hours.

Explanation:

To calculate the energy consumption in watt-hours, we first understand that the light bulb consumes 2400 watt-hours in one day. To find out how much it consumes in 3 days and 6 hours, we multiply the daily consumption by the number of days and then add the consumption for the additional 6 hours:

Energy consumed in 3 days = 2400 watt-hours/day imes 3 days = 7200 watt-hours

Energy consumed in 6 hours = (2400 watt-hours/day) / (24 hours/day) imes 6 hours = 600 watt-hours

Adding these two amounts gives us the total energy consumption in the specified time:

Total energy consumption = 7200 watt-hours + 600 watt-hours = 7800 watt-hours

Therefore, the light bulb consumes 7800 watt-hours in 3 days and 6 hours.
