Describe the transformation from y= x + 4 to y= .5x + 4 Group of answer choices compresses stretches shifts right 4 shifts left 4

Answers

Answer 1

Answer:

This type of transformation is a horizontal stretch.

Step-by-step explanation:

Given

[tex]y = x + 4[/tex]

[tex]y = .5x + 4[/tex]

Required

Determine the type of transformation

The first function can be expressed as:

[tex]f(x) = x + 4[/tex]

While the second function is:

[tex]g(x) = f(0.5x)[/tex]

Solving f(0.5x), we have to substitute 0.5x for x in [tex]f(x) = x + 4[/tex]

[tex]f(0.5x) = 0.5x + 4[/tex]

So:

The second function is:

[tex]g(x) = 0.5x + 4[/tex]

This type of transformation is a horizontal stretch.

i.e. f(x) stretched to g(x)

Round to the nearest tenth.

Answers

Answer:

1. 23.8

2. 7.7

Step-by-step explanation:

for the first blank

use sin because x is opposite and 25 is hypotenuse

set up an equation:

sin(72)= (x/25)

multiply both sides by 25:

25(sin(72))= (x/25)25

25(sin(72))= x

multiply 25 by sin(72):

23.8 = x

for the second blank

use cos because x is adjacent and 25 us hypotenuse

set up an equation:

cos(72)= (x/25)

multiply both sides by 25:

25(cos(72))= (x/25)25

25(cos(72))= x

multiply 25 by cos(72):

7.7= x

Use the Pythagorean theorem to obtain the function​ D(x) for the length of the diagonal of a double square of width x.

Answers

Answer:

[tex]D(x)= x\sqrt{2}[/tex]

Step-by-step explanation:

Given

[tex]Side = x[/tex]

Required

Represent the diagonal as a function

Using Pythagoras theorem, the diagonal is:

[tex]D^2= Side^2 + Side^2[/tex]

Substitute x for Side

[tex]D^2= x^2 + x^2[/tex]

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

Take the square root of both sides

[tex]D= \sqrt{2x^2[/tex]

Split

[tex]D= \sqrt{2} * \sqrt{x^2[/tex]

[tex]D= \sqrt{2} * x[/tex]

[tex]D= x\sqrt{2}[/tex]

Express as a function.

[tex]D(x)= x\sqrt{2}[/tex]

Given that, Danah is planting a second strawberry patch and wants it to have an area of exactly 1 square meter.

How to find the area of a second strawberry patch?

To find the area of each different shape strawberry patch, you have to find out which options have an area of 1 square meter.

Area of rectangle formula=Length×Breadth.

From option A:

Area= 1/2 × 3/2=3/4 =0.75 square meters

From option B:

Area= 2/3 × 3/2 =1 square meters

From option C:

Area= 4/5 × 5/4 =1 square meters

From option D:

Area= 2/3 × 6/4=2/2 =1 square meters

Therefore, options B, C and D have an area of 1 square meter and their length is greater than 1 meter and the width is less than 1 meter.
