Given:

The functions are:

(1) [tex]h(x)=\sqrt{1-x}[/tex]

(2) [tex]x+y=4[/tex]

(3) [tex]x^2+y^2=16[/tex]

To find:

The domain of given functions.

Solution:

Domain is the set of input and x -values.

Value under the square root must be positive because if the number under square root is negative, then it is a complex or imaginary number.

(1) [tex]h(x)=\sqrt{1-x}[/tex]

The function is defined if

[tex]1-x\geq 0[/tex]

[tex]1\geq x[/tex]

The function is defined for all real values of x which are less than or equal to 1.

Therefore, the domain of the function is (-∞,1].

(2) [tex]x+y=4[/tex]

It is a linear function and linear function is defined for all real values of x.

Therefore, the domain of the function is (-∞,∞).

(3) [tex]x^2+y^2=16[/tex]

It can be written as

[tex]y^2=16-x^2[/tex]

[tex]y=\pm \sqrt{16-x^2}[/tex]

It is defined if

[tex]16-x^2\geq 0[/tex]

[tex]16\geq x^2[/tex]

[tex]4\geq x\geq -4[/tex]

This function defined for all real values of x from -4 to 4.

Therefore, the domain of the function is [-4,4].

The geometric mean of 24 and 45 is equal to 32.86.

Given the following data:

Geometric mean is an average value that is used to indicate the central tendency of a data set containing a group of numbers, especially by determining the product of their values.

Mathematically, geometric mean is given by this formula:

[tex]G=\sqrt[n]{x_1x_2...x_n}[/tex]

Substituting the given parameters into the formula, we have;

[tex]G = \sqrt[2]{24 \times 45} \\\\G = \sqrt{1080}[/tex]

G = 32.86.

Stay safe and have a wonderful afternoon!!!!!

Step-by-step explanation:

Let w be the uniform width of the safety zone.

We have combined area = 10,800ft².

=> Combined area = Length * Width

= (80 + 2w)(50 + 2w)ft².

Therefore (80 + 2w)(50 + 2w) = 10,800.

=> 4,000 + 260w + 4w² = 10,800

=> 4w² + 260w - 6,800 = 0

=> w² + 65w - 1,700 = 0

=> (w - 20)(w + 85) = 0

=> w = 20 or w = -85

(w = -85 is rejected as width must be positive)

Hence the uniform width is 20ft.

Step-by-step explanation:

Answer:

(1)=100

Step-by-step explanation:

5.2 divided by 10= 0.52 then divide by 10 = 0.052

so instead do 5.2 divided by 100=0.052

Answer: 100

Step-by-step explanation:

Since you change the decimal place two times to the right, you divide it by 100.

The equation for the perimeter is 2(2w + 5) = 70, to calculate the width.

The internal angles of a rectangle, which has four sides, are all exactly 90 degrees. At each corner or vertex, the two sides come together at a straight angle. The rectangle differs from a square because its two opposite sides are of equal length.

Given the perimeter of a rectangular flower bed = 70 feet

and the length of  the flowerbed is 5 feet more than the width,

let width be w

length = w + 5

perimeter is given by = P = 2(l + b)

P = 2(w + w + 5)

P = 2(2w + 5)

Hence option C is correct to find the width of the rectangular flowerbed.

Answer:

7  weeks

Step-by-step explanation:

Given data

Alyssa starts with $30 and saves $5 each week

let the number of weeks be x

y= 30+5x----------1

Bill has $16 and saves $7 each

week.

y= 16+7x----------------2

equate 1 and 2

30+5x= 16+7x

30-16= 7x-5x

14= 2x

x= 14/2

x= 7  weeks

Answer: -0.5

Step-by-step explanation:

-3b = 4-2.5

-3b = 1.5

(-3b)/-3 = 1.5/-3

b = -0.5

Answer:

should be - 0.5

Step-by-step explanation:

- 3b + 2.5 = 4

1.Turn the equation around

1. -3b = -2.5 + 4.

1. The reason why you turn the 2.5 into a negative is because you basically doing the oppisite if that makes sence.

2. Add -2.5 + 4

2. -2.5 + 4 = 1.5

2. I just added.

3. Plug 1.5 into the equation. Like so

3. -3b = 1.5

3. I just replaced -2.4 + 4 with the answer

4. Divied -3b = 1.5

4. -3b/-3b = 1.5/-3b = -0.5

4. What you do to one side you have to do to the other so -3b/-3b is 0 or it just is not there anymore next you take -3b and divide it by 1.5 and get - 0.5 BAM.  

5. Plug -0.5 in for b.

5. -3(-0.5) + 2.5 = 4

Answer:

-1.5 = -3/2

-4/5 > -5/4

-3/5 = -6/10

-2/3 < 1/3

Step-by-step explanation:

If you convert -3/2 into a decimal, it equals -1.5

-5/4 is an improper fraction which makes it greater than one, but since it is negative, it is further away from zero making it less than -4/5

-3/5 is the simplified form of -6/10. 3x2= 6 and 5x2=10

1/3 is positive making it greater than any negative
