Line Z, 4y+7x=-6 is transformed by a dilation with a scale factor of 1/2 and centered at the origin. What is the equation of the line after the dilation? Type the equation using whole numbers/fractions (no decimals).

Answers

Answer 1

Answer

y=-7/4x-3/4

Step-by-step explanation:

you need to but the equation in y=mx+b form first

if you take the y and divide all other numbers.

y=-7/4x-3/2

then you already have your slope of -7/4, you don't need to divide by 1/2

you then divide the -3/2 by the 1/2 for your final answer.

A company was able to incite staff from 100 employees to 214 employees. What was the percentage increase in staff

Answers

Answer:

114%

Step-by-step explanation:

A company was able to incite staff from 100 employees to 214 employees. What was the percentage increase in staff?

Percentage Formula is given as:

New value - Old value/Old value × 100%

New value = 214

Old value = 100

Hence:

Percentage increase = 214 - 100/100 × 100

= 114/100 × 100

= 114 %

Therefore, the percentage increase = 114%

Ethan invested $9,500 in an account paying an interest rate of 2 3/4% compounded monthly. Henry invested $9,500 in an account paying an interest rate of 3 3/8% compounded quarterly. After 9 years, how much more money would Henry have in his account than Ethan, to the nearest dollar?

Answers

Answer:

691

Step-by-step explanation:

Henry would have $1,005.94 more than Ethan in his account after 9 years.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

To solve this problem, we can use the formula for compound interest:

[tex]A = P(1 + r/n)^(^n^t^)[/tex]

where A is the amount after t years,

P is the principal

r is the annual interest rate,

n is the number of times the interest is compounded per year, and

t is the time in years.

For Ethan:

P = $9,500, r = 2.75% = 0.0275 (since it is compounded monthly, n = 12), and t = 9

[tex]A = 9,500(1 + 0.0275/12)^(^1^2^\times^9^)[/tex]

= $12,817.84

For Henry:

P = $9,500,

r = 3.375% = 0.03375 (since it is compounded quarterly, n = 4), and

t = 9

[tex]A = 9,500(1 + 0.03375/4)^(^4^\times^9^)[/tex]

= $13,823.78

The difference in the amounts is:

$13,823.78 - $12,817.84 = $1,005.94

Therefore, Henry would have $1,005.94 more than Ethan in his account after 9 years.

show that the equation x^3 + x - 3 has a solution between 1 and 2

Answers

Answer:

see explanation

Step-by-step explanation:

Evaluate the polynomial at x = 1 and x = 2

x = 1 : 1³ + 1 - 3 = 1 + 1 - 3 = - 1

x = 2 : 2³ + 2 - 3 = 8 + 2 - 3 = 7

Then ( 1, - 1 ) → (2, 7 )

Shows the polynomial goes from y = - 1 to y = + 7

The change in sign indicates the graph crosses the x- axis between 1 and 2

Thus indicating a solution between x = 1 and x = 2

Write an equation for the graph below.

Answers

Answer:

y= 25x

Step-by-step explanation:

Answer:

The line can be defined as y = 25x.

Step-by-step explanation:

First we find two points that this falls on. (0, 0) and (200, 8) clearly visible points that it falls on. If we take common factors out of that, we get (1, 25).

With those points, we have the slope of the function. Slope is equal to Δy/Δx, so in this case its 25/1 or just 25

Normally, to define a line, we would take a point on it and use it as reference, defining the line as (y - y1) = s(x - x1). In this case though, because the line intersects point (0, 0), we don't even need to translate it. We can simply say:

y = sx

We already have our slope of 25, so the our line function is:

y = 25x

A scenery is painted on a paper 44cm long and 30cm wide such that there is a margin of 2cm along each of its sides. Find the total area of the margin.

Answers

Answer:

280 cm²

Step-by-step explanation:

The computation of the total area of the margin is shown below:

Given that

Length = 44 cm

Breadth = 30 cm

Area of the cardboard = 44 × 30 cm² = 1,320 cm²

Now

Length of the painting eliminating the margin is

= [44 - (2 + 2)] cm

= 40 cm

And,

Breadth of the painting eliminating the margin is

= 30 - (2+ 2)

= 26 cm

Now

Area of the painting eliminating the margin is

= (40 × 26) cm²

= 1,040 cm²

And, finally the total area of the margin is

= (1,320 - 1,040) cm²

= 280 cm²
