The value of function f+g(x) will be -5^x-3x-6 i.e. C.

What is a function?

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and co-domain or range. A function is generally denoted by f(x) where x is the input. The general representation of a function is y = f(x).

There are several types of functions in math. Some important types are:

Injective function or One to one function: When there is mapping for a range for each domain between two sets.

Surjective functions or Onto function: When there is more than one element mapped from domain to range.

Polynomial function: The function which consists of polynomials.

Inverse Functions: The function which can invert another function.

Now,

Given function are f(x)=-5^x-4

anf g(x)=-3x-2

so f+g(x) will be f(x)+g(x)

f+g(x)=-5^x-4-3x-2

=-5^x-3x-6

Hence,

           The value of function f+g(x) will be the polynomial -5^x-3x-6.

Answer:

C on edge 23

Step-by-step explanation:

Roller Coaster B has a top speed of 124.75 ft/s and has a greater top speed.

Roller Coaster A can reach a top speed of 110 ft/s, and Roller Coaster B can reach a top speed of 85 mph.

To compare the top speeds of the two roller coasters, we need to convert the speed of Roller Coaster B from miles per hour (mph) to feet per second (ft/s).

1 mile per hour = 1.46667 feet per second

So, 85 mph = 85 * 1.46667 ft/s = 124.75 ft/s

Since Roller Coaster B has a top speed of 124.75 ft/s and Roller Coaster A has a top speed of 110 ft/s, Roller Coaster B has a greater top speed.

Therefore, Roller Coaster B has a top speed of 124.75 ft/s and has a greater top speed.

The given equation is 2x+y=10.

Clearly, x=3 and y=4 satisfy this equation.

Therefore , x=3 and y=4 is one of the solution of given equation.

To find the area of  a graph and a line, you need to use the integral calculus formula.

Specifically, you will use the definite integral. The definite integral of a function f(x) over an interval [a, b] is given by the formula:

Integral of f(x)dx = F(b) - F(a)

Where F(x) is the antiderivative of f(x). To find the area of a graph, you will first need to find the antiderivative of the function. Then you will substitute the a and b values of the interval into the formula. Finally, subtract F(a) from F(b) to find the area of the graph. To find the area of a line, you will need to use the same formula. However, since the line is a straight line, the antiderivative of the line is simply the equation of the line, so the formula simplifies to:

Integral of f(x)dx = (mx + c)b - (mx + c)a

Where m is the slope of the line, and c is the y-intercept. After plugging in the a and b values of the interval, subtract (mx + c)a from (mx + c)b to find the area of the line.

Answer: 24

Step-by-step explanation:

The two triangles IFE and IHG are similar(AA Similarity).

The ratio of line IH : IF = EF : GH = 5 : 12

Therefore, 1.4x + 3 : 6.1x-6.5 = 5:12

Solve this ratio, and you'll get

16.8x+36 = 30.5x-32.5

13.7x = 68.5

x = 5

X is 5, so using X, we can find the length of HI.

30.5-6.5 = 24

Answer:

Step-by-step explanation:

The prime multiples of 4 are 2*2 or 2^2.

Answer:

Step-by-step explanation:

In a right triangle, the sine of an angle is equal to the length of the side opposite the angle divided by the length of the hypotenuse (the longest side of a right triangle, also called the hypotenuse). Therefore, to find the length of the side opposite angle θ, we can use the following formula:

opposite = sin(θ) * hypotenuse

In this case, we know that θ = 25 degrees and the adjacent side has a length of 3. Since we are dealing with a right triangle, we can use the Pythagorean theorem to find the hypotenuse:

hypotenuse = sqrt(adjacent^2 + opposite^2) = sqrt(3^2 + opposite^2) = sqrt(9 + opposite^2)

So we can substitute that value into the first equation:

opposite = sin(25) * sqrt(9 + opposite^2)

Solving for opposite, we get:

opposite = sin(25) * sqrt(9 + opposite^2)

opposite = 0.4226 * sqrt(9 + opposite^2)

We can calculate the value of sin(25) which is 0.4226.

opposite = 0.4226 * sqrt(9 + opposite^2)

opposite = 0.4226 * sqrt(opposite^2 + 9)

Square both sides of the equation to get:

opposite^2 = (0.4226 * sqrt(opposite^2 + 9))^2

opposite^2 = 0.1799 * opposite^2 + 1.5874

Subtracting 0.1799 * opposite^2 from both sides of the equation gives:

0 = 1.5874

Solving for the opposite, we get:

opposite = sqrt(1.5874)

opposite = 1.259

So the side opposite to the angle of 25 degrees is 1.259 units long, rounding to at least 3 decimal places.

The slope-intercept form of the line equation 2x+ y = 10 is y = -2x + 10

There are three type of the equation of line:

- slope-intercept form.

The equation of line is: y = mx + b

Where:

m = slope

b = y-intercept

- point-slope form

The equation of line is: y - y₁ = m(x - x₁)

Where:

m = slope

(x₁,y₁)  = a point on the line

- standard form
Ax + By + C = 0

Where A, B, C are constant

The given equation is: 2x+ y = 10

we will convert it into  slope-intercept form  y = mx + b

Subtract both sides by 2x:

2x+ y -2x = 10 -2x

y = -2x + 10

Hence, the slope-intercept form is y = -2x + 10

Strong negative correlation is 0.89. While the size of the number (0.89) suggests a strong link, the negative (-) symbol before the number implies it is negative.

Correlation coefficients demonstrate how strongly two independent variables, x and y, are connected linearly.

A linear correlation coefficient greater than zero indicates a relationship that is favorable.

A value less than zero denotes a bad relationship. To summarize, when x and y have values of 0, there is no link between them.

A statistic that describes how closely two variables' movements are related to one another is the correlation coefficient (r2).

The most widely used correlation coefficient is the Pearson product-moment correlation, which is used to detect if two variables are linearly related.

This correlation value, however, might not always be an accurate predictor of reliance in a non-linear link.

Answer:

Biblical metaphors are literary devices that can be found throughout the Bible. A biblical metaphor is a figure of speech that exists in or is otherwise connected to the Christian Bible.

It is apparent that the Bible uses metaphors a lot in its terminology (e.g., hands, eyes, feet of God, etc.). Both history and metaphor are included in the Bible.

The biblical account of creation is a complex and contested topic. Some Christians believe that the story of creation is literally true, while others believe that it is a metaphor. There are arguments to be made for both sides of this issue.

Those who believe that the biblical account of creation is literal point to the fact that the Bible is the word of God, and that God cannot lie. They also point to the fact that the scientific evidence does not support the idea of evolution.

Those who believe that the biblical account of creation is metaphorical point to the fact that the Bible is a book of poetry, and that poetry often uses metaphors and symbolism. They also point to the fact that the scientific evidence does support the idea of evolution.

In conclusion, there is no easy answer to the question of whether or not the biblical account of creation is literal or metaphorical. Christians must decide for themselves what they believe. However, it is important to note that both sides of this issue have valid arguments.

In terms of Christian teachings, it is important to remember that the Bible is a complex and multifaceted text. It contains a variety of genres, including poetry, history, prophecy, and law. As such, it is not always easy to interpret the Bible literally. In some cases, it may be more helpful to view the Bible as a metaphor or allegory. This is especially true when the Bible is talking about things that are beyond our understanding, such as the creation of the universe.

Ultimately, it is up to each individual Christian to decide how they interpret the Bible. However, it is important to remember that the Bible is a sacred text, and that it should be treated with respect.

If the slope of the line is 1/10 then it means for every ten units of horizontal distance crosses there is unit change of vertical distance.

We know that the slope of a line is nothing but the change in y coordinate with respect to the change in x coordinate.

It describes the steepness of a line.

Also,  if a line makes an angle θ with the positive direction of the x-axis, then the slope of the line will be tangent of angle θ

m = tan θ

Here we have been given a slope 1/10

Let m = 1/10

From definition of slope of line,

m = tan θ

1/10 = tan θ

θ = arctan(1/10)

θ = arctan(0.1)

θ = 5.71°

Answer:

x = 3 and y = 0     or  (3, 0)

Step-by-step explanation:

First, you use the first equation to find what y equals.

3x + y = 9

y = 9 - 3x

Next, you plug in y to the second equation.

2x - y = 6

2x - (9 - 3x) = 6

2x - 9 + 3x = 6

5x - 9 = 6

5x = 15

x = 3

Then, you plug in x in the first equation.

3x + y = 9

3(3) + y = 9

9 + y = 9

y = 0
