Anybody know how to do this?

Answer:

C!

Step-by-step explanation:

So, it's actually very simple!

If you don't know, the domain of a function is the set of x-values that make the equation true. The range, which we are trying to find, is the set of f(x), or y values that are possible.

Now, notice how in the graph, y-values don't go below 1. So there is our limit. There is nothing else limiting the y-values the other way, so its basically a single equality.

y=1 is included in the function, of course, as it goes on y=1.

So, it's [tex]y\geq 1[/tex]

Hope this helps!

Answer:

x = 3 and x = 3

Step-by-step explanation:

The given equation is

2x² - 12x + 18 = 0

Divide both sides by 2:

x² - 6x + 9 = 0

We need two numbers that will add up to -6 and their product is 9.

The two numbers are -3 and -3.

=> x² - 3x - 3x + 9 = 0

x(x - 3) - 3(x - 3) = 0

(x - 3)(x - 3) = 0

x = 3 and x = 3

Answer:

Value of Number = 8

Step-by-step explanation:

Consider the equation below;

[tex]If x - " A Number " -\\( 2 * x ) - 5 = x + 3,\\[/tex]

Now using this equation let us solve for x;

[tex]( 2 * x ) - 5 = x + 3 - Take ( 2 * x ) - 2x,\\2x - 5 = x + 3 - Add 5 on Either Side,\\2x = x + 8 - Subtract x From Either Side,\\\\x = 8, ( Solution )\\\\Conclusion ; x = 8[/tex]

Knowing this, we can say;

[tex]Value of Number = 8,\\if x - Value of Number ( Given ),\\\\Solution ; Value of Number = 8[/tex]

The value of unknown number x will be 8.

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

We have been given a statement as;

"five less than 2 times a number is equal to the sum of the number and 3"

Let the unknown number be x.

So, from the given statement,

2x- 5 = x + 3

Subtract x on both sides;

2x- 5 = x + 3

2x- 5 -x = x + 3 - x

x - 5 = 3

Add 5 on both sides;

x - 5 = 3

x = 8

Therefore, the value of unknown number x will be 8.

Step-by-step explanation:

Answer:

The ans from the bottom left

cos2(θ) + sin2(θ) = 1

sec(θ) = 1/cos(θ)

cot(θ) = cos(x)/sin(θ)

sin(θ) = -3/4

cos2(θ) + sin2(θ) = 1

cos2(θ) = 1 - sin2(θ)

cos2(θ) = 1 - 9/16 = 7/16

cos(θ) = ±√(7/16) = √7/16  (cosine is positive in Q IV)

sec(θ) = 1/cos(θ) = 4/√7

cot(θ) = cos(θ)/sin(θ) = (4/√7)/(-3/4) = -16√7/21

The exact values of secθ = 4/√7 and cotθ = -16√7/21

Trigonometric functions defined as the functions which show the relationship between angle and sides of a right-angled triangle.

Given that,

sinθ = -3/4

∵sin²(θ) +cos²(θ) = 1

∴cos²(θ) = 1 - sin²(θ)

cos(θ) = √(1 - sin²(θ))

cos²(θ) = √(1 - 9/16 )

cos(θ) = ±√(7/16) = √7/4  (cosine is positive in quadrant IV )

sec(θ) = 1/cos(θ) = 4/√7

∵cot(θ) = cos(θ)/sin(θ)

∴cot(θ)= (4/√7)/(-3/4)

cot(θ) = -16√7/21

The exact values of secθ = 4/√7 and cotθ = -16√7/21

Answer:

The Answer is: B= about 1.44mm^3

Step-by-step explanation:

hope I could help you out :)

The volume of bubble is 1.44 cubic mm.

Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.

The operator that perform arithmetic operation are called arithmetic operators .

Operators which let do basic mathematical calculation

+ Addition operation : Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation : Subtracts right hand operand from left hand operand.

for example 4 -2 = 2

* Multiplication operation : Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation : Divides left hand operand by right hand operand

Given data as :

Radius of the Bubble (r) = 0.7 mm

Volume of the bubble is given by the formula

[tex]r =\sqrt[3]{\dfrac{3v}{4\pi} }[/tex]

Taking cube on both sides

r³ = 3v/4π

Rearrange the equation,

v = 4πr³/3

Substitute the value of r in the above equation,

v = 4π(0.7)³/3

Substitute the value of π = 3.14

v = 4(3.14)(0.343)/3

v = 4.3/3

v = 1.44

Hence, the volume of bubble is 1.44 cubic mm.

1000 seconds

Step-by-step explanation:

You can start by finding the unit rate for each of them to lay down a tile. That is, how many tiles they can lay down in one second. Ralph can lay one down in 1/5 of a second, while Bob takes 1/4. 1/5+1/4=4/20+5/20=9/20 of a tile per second. Dividing 450 by 9/20, you get 1000 seconds. Hope this helps!

Answer:

A. y = -14

Step-by-step explanation:

Subtract 9 from its self and from 23 in order to isolate -y

-y + 9 = 23

- 9 -9

0 14

-y is now Isolated.

-y = 14

Generally, when you have a letter representing a number by itself such as -y, it is indicated that therecis always a 1, example -y = -1y, x = 1x, however 3y does not equal 13y or 31y. 3y already has a number in front of it so therefore, there is no need to include the number 1 in front of y.

Because -y is the same as -1y, that is a multiplation representation. -y is the same as -1 x y so the next step is to isolate y from -1. In order to do that, you will need to divide -1 by 1 and 14 by 1. (Remember, (-) (-) = + and (-) (+) = - and (+) (+) = +.)

-y = 14

-1 -1

y = -14

Answer:

Compare two fractions with different numerators and different denominators (e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as 1/2). Recognize that comparisons are valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions (e.g., by using a visual fraction model).

Answer:

84ft

Step-by-step explanation:

w = 2/3(L)

if 280 feet of fencing can enclose the garden,therefore the perimeter is 280 feet

perimeter = 2L + 2W

but W=2/3(L)

therefore, perimeter = 2L + 2(2/3L)

P= 2L + 4/3(L)

P= 10/3(L)

but P= 280

therefore 280= 10/3(L)

L = (3×280)÷10

L= 84 feet
