A poster has a rectangular printed area 100 cm by 140 cm and a blank strip of uniform width around the edges. The perimeter of the poster is 1 2 3 times the perimeter of the printed area. What is the width of the blank strip

Answers

Answer:

90 cm

Step-by-step explanation:

Given that :

Perimeter of a rectangle = 2(Length + Width)

Perimeter of print area = 2(100 + 140) = 480cm

Perimeter of entire poster :

Let uniform width of blank strip = x

x on each of the 4 sides side ;

2(2x + 100 + 2x + 140)

2(4x + 240)

8x + 480

Perimeter of poster = 1 2/3 perimeter of print area

8x + 480 = 5/2(480)

8x + 480 = 1200

8x = 1200 - 480

8x = 720

x =. 720 / 8

x = 90 cm

If the area of a square with side x is equal to the area of a triangle with base x, then find the altitude of the triangle.

Answers

Answer:

[tex]h= 2x[/tex]

Step-by-step explanation:

Given

Square

[tex]Side = x[/tex]

Triangle

[tex]Base = x[/tex]

[tex]Altitude = h[/tex]

Required

Find h, if both shapes have the same area

The area of the square is:

[tex]Area = x * x[/tex]

[tex]Area = x^2[/tex]

The area of the triangle is:

[tex]Area = \frac{1}{2} * Base*Height[/tex]

[tex]Area = \frac{1}{2} * x*h[/tex]

Equate both areas

[tex]x^2 = \frac{1}{2} * x*h[/tex]

Divide both sides by x

[tex]x = \frac{1}{2} *h[/tex]

Multiply both sides by 2

[tex]2*x = \frac{1}{2} *h*2[/tex]

[tex]2x = h[/tex]

[tex]h= 2x[/tex]

x - 2y = 8

how to answer this through elimination or substitution method?​

Answers

Answer:

The solution of the given equations

x = 3 and y =-2.5

Step-by-step explanation:

Step(i):-

  x - 2y = 8 ..(i)

3x = 19 +4y ..(ii)

By using substitution method

substituting  x = 2y +8 in equation (ii)

 ⇒  3( 2y +8) = 19 +4y

⇒   6y +24 = 19 +4y

⇒  6 y - 4y = 19 - 24

⇒   2 y = -5

   [tex]y = \frac{-5}{2} = -2.5[/tex]

Step(ii):-

Substitute 'y' = -2.5 in equation (i) , we get

         x - 2y = 8

   ⇒  x - 2( [tex]\frac{-5}{2}[/tex]) =8

  ⇒  x = 8 -5

      x = 3        

Final answer:-

The solution of the given equations

x = 3 and y =-2.5

A car is purchased for 32,000. The value of the car depreciates by 3% per year.

A. Write an exponential function to model the value of the car after t years?
B. What is the value of the car 6 years after it is purchased?

Answers

Answer:

A) car one is linear because it decreases the same amount every year.  

    car two decreases by the same ratio so it's exponential.  

B) for car one y = -6,000x + 38,000 (y is the value after x years, -6,000 is what it changes by every year, and 38,000 is the amount of year 0)

   for car two y = (44,000) (17/20)x-1 (y is the value after x years, 44,000 is the amount on year 0, and 17/20 is the ratio)

C) after 5 years car one will be 8,000

    after 5 years car two will be about 16,860

If f(x) = x², then f(2 – 3i) equals
A. -5
B. -5 – 12i
C. 13 – 12i
D. 13

Answers

Answer:

A

Step-by-step explanation:

f(2 – 3i) = (2 – 3i)^2

f(2 – 3i) = (2)^2 + (-3i)^2

f(2 – 3i) = 4 + (9)(-1)

f(2 – 3i) = 4 - 9

f(2 – 3i) = -5

These are functions in another function. The result of the function f(2-3i) is -5-12i

Composite functions

These are functions in another function. Given the function shown below;

f(x) =  x²

In order to determine  f(2 – 3i), you will replace as 2 - 3i to have:

f(2 - 3i) = (2 - 3i)²

Expand
f(2 - 3i) = 2² - 12i + 9i²
f(2 - 3i) =4 - 12i - 9
f(2 - 3i) = -5-12i

Hence the result of the function f(2-3i) is -5-12i

Which is a reasonable domain for the function f(x)=10x+8

Answers

Answer:

(-∞,∞)

Step-by-step explanation:

The domain is all possible x values of the function

There are no constraints or holes for this and therefore the domain is all real numbers

function is a relationship between inputs where each input is related to exactly one output.

x values can be ........-5,-4,-3,-2,-1, 0, 1, 2, 3, 4, 5, 6,.........

The reasonable domain for the function f(x) = 10x + 8 is (-∞, ∞).

What is a function?

function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = 10x + 8

We can have any real values of x.

f(-2) = -20 + 8 = -12

f(-1) = -10 + 8 = -2

f(1) = 10 + 8 = 18

f(2) = 20 + 8 = 28

f(3) = 30 + 8 = 28

.

.

.

x values can be ........-5,-4,-3,-2,-1, 0, 1, 2, 3, 4, 5, 6,.........

So,

The domain of the function f(x) = 10x + 8 is -∞ to ∞.

We can write as an interval as,

(-∞, ∞).

Thus,

The reasonable domain for the function f(x) = 10x + 8 is (-∞, ∞).

We are given two points of the scale: 3 and 4. Because the scale is arithmetic, we know that 3.8 must lie on 4/5s of the length between 3 and 4 to the right of 3, which is exactly where point D is.
