Boxes      0        2        5

Ratio expresses the relationship between two or more numbers. It is the number of times that one value is contained within other value(s).

The ratio of snakes to frogs can be determined by counting the number of snakes and frogs.

Number of snakes = 4

Number of frogs = 8

The ratio of snakes to frogs - 4 : 8 = 1 : 2

The ratio of frogs to animals = number of frogs : number of animals = 8 : 12 = 2 : 3.

Number of snakes if 3 more are added = 4 + 3 = 7

Ratio of snakes to frogs - 1 : 2  

Number of frogs that would keep the ratio constant = 7 x 2 = 14

Number of frogs that should be added = 14 - 8 = 6

The domain of the function is [ - 6 , ∞ ]

A radical function is the one provided.

It should be noted that a radical function can only be specified for values that will result in the radicand being larger than or equal to zero.

As a result, either the radicand of the provided function must be larger than or equal to zero, or:

Thus we can write it as

x + 6 ≥ 0

subtract 6 from both LHS and RHS

x + 6 - 6 ≥ 0 - 6

x ≥ - 6

A. The data modeling the relation is an exponential function.

B. The function is: y = 2^x.

C. The rate of change from x = 2 to x = 4 is of 4.

The definition of an exponential function is presented as follows:

[tex]y = ab^x[/tex]

In which the variables of the function are listed as follows:

From this data-set, when x increases by one, y is multiplied by 2, hence the rate of change is:

b = 2.

When x is increased by n, the rate of change is:

b^n = 2^n.

Hence, when x is increased by 2, from 2 to 4, in item c, the rate of change is:

2² = 4.

When x = 1, the output is the output at x = 0 multiplied by 2, hence the coefficient a of the function is given as follows:

Answer:272

Step-by-step explanation:

The length of the square for the 2.25 inches King's height will be 0.75. The correct option is A.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that, a chessboard is made using the ratio of square length to the king's height, 1.5 inches to 4.5 inches. If a chessboard is made with a king's height of 2.25 inches.

The square length will be calculated as,

Square length / Kings Height = 1.5 / 4.5

Square length = (King's height x 1.5 ) / 4.5

Square length = ( 1.5 x 2.25 ) / 4.5

Square length = 0.75 inches

Therefore, the length of the square for the 2.25 inches King's height will be 0.75. The correct option is A.

when x=-3, 11x+6 = -33+6=-27,

2x+28x+48= 30x+48=-90+48=-42

Answer:

I got 28, -27, 108, and -42. See explanation for the answer for which problems

Step-by-step explanation:

11x + 6 = ?

2x + 28x + 48 = ?

x = 2 and x = -3

Let's start with the first equation

Using x = 2

11(2) + 6 = ?

22 + 6 = 28

Using x = -3

11(-3) + 6 =?

-33 + 6 = -27

Second equation

Using x = 2

2(2) + 28(2) + 48 = ?

4 + 56 + 48 = 108

Using x = -3

2(-3) + 28(-3) + 48 = ?

The expression that equals semantics -1 D is - 2x² + x + 15.

One or more terms in an algebraic expression each include variables and constants. These expressions utilize separators like +, -, and that are symbols or operations. An algebraic statement with variables and constants is a quadratic trinomial. It is written as ax² + bx + c, where a, b, and c are real non-zero values and x is the variable. The leading coefficient "a," linear coefficient "b," and additive constant "c" all refer to the same constant.

The given trinomial is D = 2x² - x - 15

Multiply both sides by -1 to find -1D

-1D = -( 2x² - x - 15) = 0

-1 D = - 2x² + x + 15

Step-by-step explanation:

the answer is 3/2 because you take the slope by using the equation y/x. I did this problem by starting prop the point (0,-6). I then counted for how many points I went up, how many did I go to the right or left. If it went to the right it’s positive, to the left it is negative. In this case it went to the right 2 times every time it went up 3. Meaning 3/2

a) The mistake that mara made in step 3 is that; she didn't apply the basic rule of logarithm which should have given the expression log 3^x = x log 3

b) The mistake that mara made in step 4 is that; you must eradicate the log at the same time and as such it should be x log 3 = 3log 3

c) The mistake she made throughout is not applying the basic rule of logarithm.

She is trying to solve the exponential function 7 x 3^x = 189 with the following steps;

Step 1. 7 x 3^x = 189

Step; 2. 3^x = 27; This step is correct because she got it by using division property of equality to divide both sides by 7.

Step 3; log^3 (^3) = log^27; This step is incorrect because from basic rules of logarithm, we know that; log 3^x = x log 3

Step 4. xlog^33=9; This is incorrect because you cannot remove the log on one side of the equation without doing the same on the second side. Thus, what she she should have had here is;

x log 3 = 3log 3

Step 5. x * 1 = 9; This is wrong because dividing both sides by log 4 gives; x = 3

The expression will be; part (a) (f o g)(-2) = 2 and part (b) (g o f)(-2) = -95

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Given the functions as;

f(x)=4x-2

g(x)=5-x^2

We need to find (f o g)(-2)

So, first, we will find the function (f o g)(x) as follows:

[tex]\begin{gathered} \mleft(f\circ g\mright)(x)=f\lbrack g(x)\rbrack=4(5-x^2)-2 \\ (f\circ g)(x)=20-4x^2-2 \\ (f\circ g)(x)=18-4x^2 \end{gathered}[/tex]

Now, substitute with x = -2 then we get;

[tex](f\circ g)(-2)=18-4\cdot(-2)^2=18-4\cdot4=18-16=2[/tex]

Thus, the answer to the part is (a) (f o g)(-2) = 2

b) (g o f)(-2)

We need to find (g o f)(x) as follows:

[tex](g\circ f)(x)=g\lbrack f(x)\rbrack=5-(4x-2)^2[/tex]

Now Substitute with x = -2, then we get;

[tex]\begin{gathered} (g\circ f)(-2)=5-(4\cdot-2-2)^2 \\ =5-(-8-2)^2 \\ =5-(-10)^2 \\ =5-100 \\ =-95 \end{gathered}[/tex]

The probability of rolling a number that is less than 3 is P = 1/2.

A standard six-sided die has the following outcomes:

{1, 2, 3, 4, 5, 6}

The outcomes that are less than or equal to 3 are:

{1, 2, 3}

Assuming all the outcomes have the same probability, the probability of rolling a number less than or equal to 3 on a standard six-sided die will be equal to the quotient between the number of outcomes that meet the condition and the total number of outcomes.

A number line is a representation of a graduated straight line in elementary mathematics that serves as a visual representation of the real numbers. It is assumed that every point on a number line corresponds to a real number, and that vice versa.

Research has revealed that number lines are crucial because they foster sound mental number sense and arithmetic procedures.

They assist in providing a mental approach for addition and subtraction. Number lines are crucial, we can all agree on that.

Number lines are significant because they depict numbers as they appear in daily life.
