===================================================

Explanation:

I've highlighted lines m and k in red (see diagram below). We'll ignore the other lines. On those red lines, I've added blue points with their coordinate locations.

Line m has point A = (-3, 5) and B = (-1, -3). Let's use the slope formula to find the slope through these points

m = (y2-y1)/(x2-x1)

m = (-3-5)/(-1-(-3))

m = (-3-5)/(-1+3)

m = -8/2

m = -4

The slope of line AB, aka line m, is -4.

-------------

Line k has points C = (1, 5) and D = (3, -3) on it. We'll use the slope formula to get...

m = (y2-y1)/(x2-x1)

m = (-3-5)/(3-1)

m = -8/2

m = -4

The slope of line CD, aka line k, is -4

---------------

Both lines m and k have the same slope of -4. Therefore, the two lines are parallel. Parallel lines always have the same slope, but different y intercepts. So these lines will never intersect one another.

Answer:

36

Step-by-step explanation:

if we were decreasing it would be 9 but if we are increasing it, it would be 36

just multiply by 2 or divide by 2

Answer:

27

Step-by-step explanation:

increasing by 1 half is like dividing. 4 increased by one half would be 6, because half of four is 2, and you add that on to four. increasing 18 by half, divide 18 by 2, that = 9 then add 9 onto 18. the answer is 27

Answer:

70

Step-by-step explanation:

half of a circle is 180 degrees

180 - 52 = 128

128 - 58 = 70

To check your answer

70 + 58 = 128

128 + 52 = 180

Answer:

Option 1

Step-by-step explanation:

Effective Interest Rate = [ 1 + ( r / m) ]^ mt -  { 1 }

where i = nominal interest rate , n = number of compounding per time period, t = number of time periods

Option 1 : Interest rate 'i' = 2% , Quarterly compounding 'n' = 4 , t = 25 years  

EAR  = [ 1 + 2% / 4 ]^ (4 x 25) - [ 1 ]  = 0.6466 , ie 64.66%

Option 2 :  Interest rate 'i' = 2% , Monthly compounding 'n' = 12 , t = 25 years  

EAR = [ 1 + 1.5% / 12 ] ^ (12 x 25) - [ 1 ] = 0.4546 , ie 45.46%

As option 1 has higher EAR than option 2, former is better than latter

Answer:

Answer:

1.05 * 10⁰

Step-by-step explanation:

Standard form is a way of representing either very large or very small numbers easily.

If a number is to be written in standard form, you have to first write down the number between 1 and 10, then you write × 10(to the power of a number).

Given that the amount of rain that fell near Marie's house is one and five hundredths inches of rain.

Amount of rain = one and five hundredths inches of rain = 1 + 5/100 = 1 + 0.05 = 1.05

Amount of rain in standard form = 1.05 * 10⁰

Answer:

<A = 56degrees

<B = 34degrees

<C = 56degrees

Step-by-step explanation:

From tyhe diagram, the sum of m<C and m<D is 180degrees. Hence;

<C + <D = 180

<C + 124 = 180

<C = 180 - 124

<C = 56degrees

Also;

<B + 90 + <C = 180

<B + 90 + 56 = 180

<B  + 146 = 180

<B = 180 - 146

<B = 34degrees

Similarly;

<A + <B = 90

<A + 34 = 90

<A = 90 - 34

<A = 56degrees

Answer:

3rd option

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the rate of change and c the y- intercept )

Given

2x + 8y = - 4 ( subtract 2x from both sides )

8y = - 2x - 4 ( divide terms by 8 )

y = - [tex]\frac{2}{8}[/tex] x - [tex]\frac{4}{8}[/tex] , that is

y = - [tex]\frac{1}{4}[/tex] x - [tex]\frac{1}{2}[/tex] ← in slope- intercept form

with rate of change m = - [tex]\frac{1}{4}[/tex] and y- intercept c = - [tex]\frac{1}{2}[/tex]

Answer:

See the detailed answers below

Step-by-step explanation:

Given data

Ratio=  1:4:7

combined ratio= 1+4+7= 12

Total amount= $636,000

Apply the part to all method

The first person will take

1/12= x/ 636,000

cross multiply

12x= 636,000*1

x= 636,000/12

x= 53000

The second person will take

4/12= x/ 636,000

cross multiply

12x= 636,000*4

x= 2544000/12

x= 212000

The third person will take

7/12= x/ 636,000

cross multiply

12x= 636,000*7

x= 4452000/12

x= 371000

Answer:

Slop of the line M = -2

Step-by-step explanation:

Given coordinates;

(-1 , 1) , (3 , -7)

Find:

Slop of the line

Computation:

We know that;

x1 = -1

x2 = 3

y1 = 1

y2 = -7

Slop of the line M = Δy / Δx

Slop of the line M = (y2 - y1) / (x2 - x1)

Slop of the line M = (-7 - 1) / [3 - (-1)]

Slop of the line M = (-8) / [3 + 1]

Slop of the line M = (-8) / (4)

Slop of the line M = -2

Answer:

the corect answer for this question is

(4,3-)

Answer:

A

Step-by-step explanation:

the line going horizontal(left to right), is the y line

the line going vertically (up and down), is the x line

now that we know where the x and the y lines are at, now we apply it to the format, (x,y)

where the y and x line meet is the origin (0,0), going left or down make the number a negative. up and right make the number positive

Answer:

$1783.03

Step-by-step explanation:

Annually compounding interest formula:

PV(1+i)ⁿ

1500(1+.025)⁷

1500(1.025)⁷

1783.028631

which rounds to

1783.03

Answer:

$1783.03

Step-by-step explanation:

You use the formula for finding the interest rate.

So 1500(1+.025)^7

Which you put that in a calculator and it comes to out to 1783.0286. Then just round up.

Answer:

2.5

Step-by-step explanation:

273/280 = 97.5%

2.5% are defective

If 280 units of that model are tested, and the manufacturer finds 273 headsets without any defects, There is a 2.5% chance of finding a defective headset.

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

A manufacturer tests a certain number of the headsets that are produced each day.

If 280 units of that model are tested, and the manufacturer finds 273 headsets without any defects,

The chance of finding a non-defective headset

= 273/280

= 97.5%

The chance of finding a defective headset

= 100% - 97.5%

= 2.5% are defective
