Answer:

domain is x = 3

Thus domain means that for every fruit cup costs $3

Range is f(20) = 60

Step-by-step explanation:

We are given;

Total students for the fruit cup party = 18

Total teachers for the fruit cup party = 2

Cost of each fruit cup =$ 3

Delivery charge = $ 10

Now, the total number of people attending the party = Total number of students + Total number of teachers

Thus;

Total number of people attending party = 18 + 2 = 20

Since cost of each fruit cup is $3.

Thus, for 20 fruit cups, the function is;

f(x) = 20x where x is cost of each fruit cup.

It means the cost of 20 fruit cups = $3 × 20 = $60

Thus, domain is x = 3

Thus domain means that for every fruit cup costs $3

Range is f(20) = 60

Answer:  yours is correct

Step-by-step explanation:

Since P = -2 and D = 5,

P - D = -2 - 5 = -7

P + D = -2 + 5 = 3

D - P = 5 - -2 = 7

this makes P - D the smallest, and D - P the largest

Answer:

[tex]\dfrac{\sqrt3}{4}[/tex]

Step-by-step explanation:

The given expression is :

[tex]x=\dfrac{3}{4\sqrt{3} }[/tex]

Multiplying both numerator and denominator by [tex]\sqrt{3}[/tex],

[tex]x=\dfrac{3}{4\sqrt{3} }\times \dfrac{\sqrt{3} }{\sqrt{3} }\\\\=\dfrac{3\sqrt3}{4\times 3}\\\\=\dfrac{\sqrt3}{4}[/tex]

So, the rationalized form of the given expression is [tex]\dfrac{\sqrt3}{4}[/tex]

Answer: 7 feet

Step-by-step explanation:

1 foot = 12 inches

7 * 12 = 84

7 feet = 84 inches

84 inches are more than 81 inches

Answer:

7 feet is greater

Step-by-step explanation:

you can change feet to inches. one foot is the same as 12 inches. so 7 feet = 84 inches. so 84 > 81 so 7 feet is greater

Answer:

9) we get value of x: [tex]\mathbf{x=-4+\sqrt{42}\:i, x=-4-\sqrt{42}\:i}[/tex]

Option C is correct.

10) The difference is [tex]2k^3+3k-1[/tex]

Option A is correct.

Step-by-step explanation:

9) We need to solve:

[tex]x^2+8x+58=0[/tex]

Solving using quadratic formula: [tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

We have a=1, b=8 and c=58

Putting values and finding value of x

[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\x=\frac{-8\pm\sqrt{(8)^2-4(1)(58)}}{2(1)}\\x=\frac{-8\pm\sqrt{64-232}}{2}\\x=\frac{-8\pm\sqrt{-168}}{2}\\We\:know\sqrt{-1}=i \\x=\frac{-8\pm2\sqrt{42}\:i}{2}\\x=\frac{2(-4\pm\sqrt{42}\:i)}{2}\\x=\frac{2(-4+\sqrt{42}\:i)}{2}, x=\frac{2(-4-\sqrt{42}\:i)}{2}\\x=-4+\sqrt{42}\:i, x=-4-\sqrt{42}\:i[/tex]

So, we get value of x: [tex]\mathbf{x=-4+\sqrt{42}\:i, x=-4-\sqrt{42}\:i}[/tex]

Option C is correct.

10) [tex](5-2k^3-5k)-(-4k^2+6-8k)[/tex]

Combining like terms and subtracting:

[tex](5-2k^3-5k)-(-4k^3+6-8k)\\=5-2k^3-5k+4k^3-6+8k\\=-2k^3+4k^3-5k+8k+5-6\\=2k^3+3k-1[/tex]

The difference is [tex]2k^3+3k-1[/tex]

Option A is correct.

Answer:

y = -x + 8

Step-by-step explanation:

The equation can be written as;

y = mx + b

where b is the y-intercept

From the diagram , b= 8

y = mx + 8

To get m, substitute (8,0 ) into the equation

0 = 8x + 8

x = -8/8

x = -1

So the full equation is;

y = -x + 8

Answer:

4 * 14 = 56

Step-by-step explanation:

56/2 = 28

28/2 = 14

14/2 = 7

7/7 = 1

56 = 2 * 2 * 2 * 7

56 = (2 * 2) * (2 * 7)

56 = 4 * 14

Answer:

7.6158 feet

Step-by-step explanation:

The rise and run form the shorter sides of a right triangle with the hypotenuse as the surface (see figure)

Hypotenuse (surface length) is given by the Pythagorean formula

[tex]c = \sqrt{a^2 + b^2}[/tex] where c is the hypotenuse and a, b the shorter sides

Here
[tex]\sf c = \sqrt{7^2 + 3^2} = \sqrt{49 + 9} = \sqrt{58} = 7.6158\;feet[/tex]

Step-by-step explanation:

The perimeter of this figure, to the nearest unit, is 37.9 units and the area of this figure, to the nearest square unit is 153.54 square units.

It is defined as a two-dimensional geometry that has four sides and four vertices. The sides of the square are equal in length. It is a regular quadrilateral.

We have a figure shown in the picture made with squares and circles.

To find the perimeter of the figure.

First, calculate the circumference of the circle portion.

The circumference of the 1/4 circle = (1/4)2πr

The radius of the circle r = 5 units

The circumference of the 1/4 circle = (1/4)2π(5)

The circumference of the 1/4 circle = 7.85 units

The perimeter of the figure = 10 + 5 +7.85 + 5 + 10

The perimeter of the figure = 37.85 units ≈ 37.9 units

The area of the figure = area of the square - an area of the square(5×5) +

area of the 1/4 circle

The area of the figure = 10×10 - 5×5 + π(5)²

The area of the figure = 100 - 25 + 78.53

The area of the figure = 153.54 square units

Thus, the perimeter of this figure, to the nearest unit is 37.9 units and  the area of this figure, to the nearest square unit is 153.54 square units.

We need to know about inequality to solve this problem. The solution of the inequality is x>-4/3.

Inequality represents the comparison between two unequal expressions. Two expressions can be related to each other as greater than, less than,greater than or equal to or less than or equal to. While solving inequality we always have to keep in mind the change of sign and corresponding change of the comparison. Here in the question we have an inequality of the variable x, we have to get a solution for x by solving this inequality.

6x+4>-3x-8

6x+3x>-8-4

9x>-12

x>-4/3

Therefore the solution set that we get from the inequality 6x+4>-3x-8 is x>-4/3.

Answer:

its c

Step-by-step explanation:

Our denominators are 40 and 4. What we need to do is find the lowest common denominator of the two numbers. This is the smallest number that can be divided by both 40 and 4. In this case, the lowest common denominator is 40.

If we multiply the first denominator (40) by 1 we will get 40. If we multiply the second denominator (4) by 10 we will also get 40. We also need to multiply the numerators above the line by the same amounts so that the fraction values are correct:

33 x 1

40 x 1

3 x 10

4 x 10

This is what 33/40 and 3/4 looks like with the same denominator:

33

40

&  

30

40

Now that these fractions have been converted to have the same denominator, we can clearly see by looking at the numerators that 33 is greater than 30 which also means that 33/40 is greater than 3/4.
