x^2+y^2=25 find the distance of point (x,y) from origin​

Answer:

C and D

Step-by-step explanation:

D is the exact same.

For C this is already proven but you can test this by choosing any number for K (4) and multiply it by 1/2. You get 2 which is the same as 4/2.

The expression which is equivalent to the expression, K/2 is; Choice D: k/2.

According to the question;

Among the choices; Choice D: k/2 is the exact same as the expression K/2.

However, Choice C if written as (1/2)k is equivalent to k/2 as they both mean half of k.

where P=monthly payments, i= interest rate n=period

Given ;

P= $250   n=9months and i=6%(0.04) per year, find savings balance?

Answer:

Option B is correct

Step-by-step explanation:

The graph represent  the negative correlation.

In negative correlation there is inverse relationship between two variables. If value of one variable is increasing then the value of other variable is decreasing.

As seen from the graph when the value of x is increasing the value of variable y is decreasing

So, Option B negative correlation is correct.

Answer:

Step-by-step explanation:

To find a significant figure you just count how many numbers are before and after the decimal place but if the first number is zero then it does not count.

Final answer:

The values with 3 significant figures are A. 10.1 and D. 129, as non-zero numbers are always significant, and there are no leading, captive, or trailing zeros to consider in these cases.

Explanation:

The values that have 3 significant figures are:

A. 10.1

D. 129

In A, all the digits are significant because they are all non-zero numbers. In D, similarly, all digits are significant since non-zero numbers are always counted as significant figures.

For the options not chosen:

B. 100.05 has 5 significant figures because zeros between non-zero numbers are significant and so are the ending non-zero numbers.

C. 120 may be seen as having 2 or 3 significant figures depending on whether the zero is considered significant; additional context such as writing the number in scientific notation or a decimal point (120.) is needed to clarify its significance.

Answer:

(3x - 4)(8x - 3)

Step-by-step explanation:

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 24 × 12 and sum = - 41

The required factors are - 32 and - 9

Use these factors to split the x- term

24x² - 32x - 9x + 12 ( factor the first/second and third/fourth terms )

= 8x(3x - 4) - 3(3x - 4) ← factor out (3x - 4) from each term

= (3x - 4)(8x - 3) ← in factored form

Answer:

300 ft-lbs

Step-by-step explanation:

For work like this,

Just multiply 100 times 3.

You always just multiply the two numbers

Example:

Calculate the work done.

A crane lifts 5,000 newtons to the top of a roof which is 6 meters high.

3,000 ft-lbs

30,000 Nm

5,000 Nm

300 Nm

5,000 x 6 = 30,00

it can also be done like this

5 x 6 = 30

+ 00 = 30,00

The work done is 300 ft-lbs, the correct option is D.

The multiplication of the magnitude of displacement d and the component of the force that is in the direction of displacement is called work done.

Work done is positive when the energy leaves the system. Here, the system is making an effort on the surroundings.

A tractor pulls a heavy log with a force of 100 pounds.

The log moves 3 feet.

The work done is given by;

[tex]\rm Work \ done=Force \times Displacement\\\\Work \ done= 100 \times 3 \\\\Work \ done=300\ ft-lbs[/tex]

Hence, the work done is 300 ft-lbs, the correct option is D.

Surface Area of Cuboid:

A cuboid has 6  rectangular faces, the surface area of the whole cuboid is the sum of 6 rectangular surface areas of cuboid.

surface area = l x b + b x h + h x l + l x b + b x h + h x l

Surface area of cuboid = 2 x ((l x b) + (b x h) + (h x l))

When the length of each side is cut in half so, l, b and h decreases by 2.

l =  [tex]\frac{l}{2}[/tex] = [tex]\frac{11}{2}[/tex] = 5.5cm

b = [tex]\frac{b}{2}[/tex] = [tex]\frac{10}{2}[/tex] = 5cm

h = [tex]\frac{h}{2}[/tex] = [tex]\frac{12}{2}[/tex] = 6cm

First you want to find the area of the driveway. The easiest way to do this is to separate the rectangles. The area of the small rectangle will be 6 because 2x3=6, the area of the large rectangle will be 216 because 18x12=216. Then you will add the two areas back together, 216+6=222. Using the formula volume=baseXheight you will do 222x15 to get 3,330 cubic meters (because height and depth work the same)

The volume of the driveway is calculated by multiplying the area of the driveway by the thickness. The volume will be in cubic meters if all measurements are in meters. For accurate calculation, more specific dimensions are needed beyond just perimeter and thickness.

To help calculate the volume of the concrete used in the driveway, you'll need the perimeter and the thickness of the driveway. The perimeter being stated as 64m doesn't give us enough detail because to calculate the volume of a prism (which the driveway essentially is), we need the area of the base (in this case the area of the driveway's surface), not just the perimeter.

However, if we assume that the driveway is of a standard shape like a rectangle and you also have the structural width, you could calculate the area and then the volume. Here's a generic explanation:

1. If you have a rectangular drive, area would be calculated as length * width.

2. You then calculate volume by multiplying the area by the thickness of the driveway. That is, Volume = area * thickness.

Note: This will give you the volume in cubic meters provided all measurements were in meters.

For us to compute this for your driveway, we'd need more dimensions in addition to the 15m thickness and 64m perimeter.

Answer:

The distance between the police station and the fire station is 4 miles

Step-by-step explanation:

* Lets study the situation in the problem to solve it

- In the city there are three places, library , police station and fire station

- The distance between the library and the police station is 3 miles

  less than twice the distance between the police station and the

  fire station

- The distance between the library and the police station is 5 miles

* Lets change all of these situation to equations

# Let the distance between the library and the police station is x

# Let the distance between the police station and the fire station is y

∵ The distance between the library and the police station (x) is 3 miles

  less than twice the distance between the police station and the

  fire station (y)

∴ x = 2y - 3

∵ The distance between the library and the police station is (x) 5 miles

∴ x = 5

- Substitute the value of x in the equation above

∵ x = 2y - 3

∵ x = 5

∴ 5 = 2y - 3 ⇒ add 3 to both sides

∴ 8 = 2y ⇒ divide both sides by 2

∴ 4 = y

∵ y is the distance between the police station and the fire station

∴ The police station is 4 miles apart from the fire station

* The distance between the police station and the fire station is 4 miles

what about this picture/function/expression?

well, we have 3 points over the y-coordinate, but but but, every point has the same x-coordinate, whatever that might be, and so they form a vertical line.

does this straight vertical line pass the vertical line test? nope.

other way to see it is, a function has no x-repeats, the x-coordinate for every point must not be repeated, in this case it is the same for all, so it repeats thrice, so is not a function, just a relation.

Answer:

It turns out that all three altitudes always intersect at the same point - the so-called orthocenter of the triangle. The orthocenter is not always inside the triangle. If the triangle is obtuse, it will be outside. To make this happen the altitude lines have to be extended so they cross.

To solve this you must use a proportion like so...

[tex]\frac{part}{whole} = \frac{part}{whole}[/tex]

60 is a percent and percents are always taken out of the 100. This means that one proportion will have 60 as the part and 100 as the whole

We want to know out of what number is 12 60%. This means 12 is the part and the unknown (let's make this x) is the whole

[tex]\frac{12}{x} =\frac{60}{100}[/tex]

Now you must cross multiply

12*100 = 60*x

1200 = 60x

To isolate x divide 60 to both sides

1200/60 = 60x/60

20 = x

This means that 60% of 20 is 12
