Answer:

[tex]\text{c. }r>0[/tex]

Step-by-step explanation:

Define a positive number by all real numbers greater than, but not including, zero.

The inequality that represents this is [tex]\boxed{\text{c. }r>0}[/tex]

*Note: The sign [tex]\geq[/tex] represents including the value following it. However, we do not want to include zero in our set, hence [tex]r>0[/tex]

Answer:

r > 0

Step-by-step explanation:

a. r≤ 0            the equation is represented as r value is equal to zero or less than zero. So r can be zero or negative since its saying less than zero.

b. r≥ 0            the equation is represented as r value is greater than but equal to zero. So r can be zero and nonpositive.

c. r> 0            the equation is represented as r value greater than 0 which makes the answer positive.

d. r≤ ∞           the equation is represented as r value is equal to all positive integers but all negative integers.

e. r< ∞           the equation is represented as r value is all negative numbers since the inequality sign is less than

Answer:

[tex]\rm Slope = -1[/tex]

Step-by-step explanation:

Given :-

And we need to find out the gradient of the line. parallel to the given line .The gradient of the line is the " slope " of the line. The given equation is in slope Intercept Form , which is ,

Slope intercept form :-

[tex]\rm\implies y = mx + c [/tex]

On comparing it to slope Intercept Form , we have ,

[tex]\implies \rm Slope (m) = (-1)[/tex]

And the slope of the line , parallel to a line is same as that of the given line. Therefore they will have same gradient.

[tex]\implies \boxed{\rm Slope_{(||\ line)} (m) = (-1)}[/tex]

Hence the gradient of the line is (-1) .

Answer: 2/3πx³

Step-by-step explanation:

Let the radius of the cone be represented by x.

Since the height of the cone is twice the radius of its base, the height will be: = 2x

Volume of a cone = 1/3πr²h

where,

r = x

h = 2x

Volume of a cone = 1/3πr²h

= 1/3 × π × x² × 2x

= 1/3 × π × x² × 2x

= 1/3 × π × 2x³

= 2/3πx³

Therefore, the correct answer is 2/3πx³.

This System of Quadratic equation is intersects at zero place.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The quadratic equation is,

- x² + x + 6 = 2x + 8

Now,

The quadratic equation is;

- x² + x + 6 = 2x + 8

x² + 2x - x + 8 - 6 = 0

x² + x + 2 = 0

So, The solution of the quadratic equation is solve as;

x = - 1 ± √1² - 4 × 1 × 2 / 2 × 1

x = -1 ± √1 - 8 / 2

x = - 1 ± √-7 / 2

x = - 1 ± √7i / 2

Clearly, It has no real solution do, it cannot cut at any point.

Therefore,

This System of Quadratic equation is intersects at zero place.

S(-8,-3), T(0, -3), and U(-7, -8)

Step-by-step explanation:

for all of the coordinates, you would subtract 8 from their X-values, and subtract 13 from their Y-values.

By finding a common factor, we can rewrite the expression as:

54 + 72 = 18*(3 + 4)

The distributive property says that we can write:

C*(A + B) = C*A + C*B

In this case, we want to rewrite the expression:

54 + 72

So the first thing we need to find is a common factor between these two numbers.

We can rewrite these as:

54 = 2*3*3*3

72 = 2*2*2*3*3

The maximum common factor between these two nmbers is:

2*3*3 = 18

Then we can rewrite:

54 = 18*3

72 = 18*4

Then we can rewrite the expression as:

54 + 72 = 18*3 + 18*4 = 18*(3 + 4)

Answer:

[tex]f(g(5)) = 0[/tex]

Step-by-step explanation:

Given

[tex]f(x) = x+ 2[/tex]

[tex]g(x) = x^2 - 27[/tex]

Required

[tex]f(g(5))[/tex]

First, calculate [tex]f(g(x))[/tex]

We have:

[tex]f(x) = x+ 2[/tex]

Substitute [tex]g(x)[/tex] for x

[tex]f(g(x)) = g(x) + 2[/tex]

Substitute [tex]g(x) = x^2 - 27[/tex]

[tex]f(g(x)) = x^2 -27+ 2[/tex]

[tex]f(g(x)) = x^2 -25[/tex]

Substitute 5 for x

[tex]f(g(5)) = 5^2 -25[/tex]

[tex]f(g(5)) = 25 -25[/tex]

[tex]f(g(5)) = 0[/tex]

Step-by-step explanation:

Comparing the maple tree and the pine tree growth information, the tree that grows faster is the pine tree.

A mathematical function called an exponential function is employed frequently in everyday life. It is mostly used to compute investments, model populations, determine exponential decay or exponential growth, and so on.

Exponential function is a type of function of the form: f(x) = a(b)^x. It is made up of  3 main parts

a = the starting or initial value

b = the base function

x = the exponents

Considering the given problem,  b for maple is given as 1.5 and we calculate for pine using the data in the table. the equation is derived as follows

f(x) = a(b)ˣ

12 = a(b)¹

24 = a(b)²

dividing 24 = a(b)² by 12 = a(b)¹

b = 2

hence for pine tree the b is 2 which is greater than 1.5

Let the amount Tom does = x

Then Larissa’s time would be 3x( 3 times the amount of Tom)

And Neal would also be 3x

The total of the 3 is 84 hours so as an equation you have:

X + 3x + 3x = 84

Combine like terms

7x = 84

Divide both sides by 7

X = 84/7

X = 12 hours

Tom = x, so Tom exercised for 12 hours.

The domain of the function whose graph shown in diagram is x ≤ 1.

The range of values that we are permitted to enter into our function is known as the domain of a function. The x values for a function like f make up this set (x). A function's range is the collection of values it can take as input.

Consider the function y = f(x), which has the independent variable x and the dependent variable y. A value for x is said to be in the domain of a function f if it successfully allows the production of a single value y using another value for x.

The domain of the function whose graph shown in diagram is x ≤ 1 as the value of x is less than 1.
