Explanation:

Start at -1 on the x axis number line. Then move vertically until reaching the function curve. You should arrive at (-1,2). This tells us that g(-1) = 2. In other words, the input x = -1 leads to the output y = 2.

Follow similar steps to find that g(1) = -2

Therefore, g(-1)+g(1) = 2 + (-2) = 0

For the given graph:

And yes, it is a function.

For a given function y = f(x), the domain is the set of the inputs (possible values of x) and the range is the set of outputs (possible values of y).

To identify the domain we need to look at the x-axis (the horizontal one)

We can see in the left side that the first value is -2, whith a closed circle, meaning that the value belongs to the domain.

The right side is x = 0, with a open circle, which means that it does not belong to the domain.

Then the domain is D: [-2, 0)

Similarly, by looking at the y-axis (vertical axis) we can find the range which is:

R: [0, 2)

Finally, how to know if this is a function?

There is something called the "vertical line test". This test says that if you can't draw a vertical line that intersects the graph in two points or more, then it is a function.

And the graph clearly meets that test, so it is a function.

Answer:

  -8.8x +5

Step-by-step explanation:

You want to simplify the expression -0.8x+40-8x-35.

The expression is simplified by combining like terms. Like terms have the same (set of) variables.

  -0.8x +40 -8x -35

  = -0.8x -8x +40 -35 . . . . . . group like terms

  = (-0.8 -8)x +(40 -35)

The length of the hypotenuse is given by the function h(x) = √[x² + (10/x)²]

An equation is an expression that shows the relationship between two or more numbers and variables.

The area of the right triangle is 5 in², the length of the leg is x, hence:

Area = (1/2) * base * height

5 = (1/2) * x * height

height = 10/x

hypotenuse = √[(leg)² + (height)²]

h(x) = √[x² + (10/x)²]

The length of the hypotenuse is given by the function h(x) = √[x² + (10/x)²]

The required answer for the given equation is d = 1/2, ±√14.

The division is one of the four basic mathematical operations, the other three being addition, subtraction, and multiplication.

Now the given equation is,

420 ÷ d = 30d = 15

Now if,

30d = 15

Then divide both the side by 30 we get,

30d/30 = 15/30

Solving we get,

d = 1/2

this is the required value of d

Now if,

420 ÷ d = 30d

So simplifying it we get,

420/d = 30d

multiplying both the side by d we get,

d*420/d = 30d*d

Solving we get,

30d^2 = 420

Dividing both the side by 30 we get,

30d^2/30 = 420/30

Solving we get,

d^2 = 14

Taking square root both the side we get,

√d^2 = √14

Solving we get,

d = ±√14
this is the required value of d.

Thus, the required answer for the given equation is d = 1/2, ±√14.

Answer: 17 strings

Step-by-step explanation:

let the number of strings be a

let the number of beads on each string be b

a − b = 10 (first equation)
a × b = 119 (second equation)

From the first equation:

a = 10 + b

substitute first equation into second equation
b × (10 + b) = 119
10b + b² − 119 = 0
b = 7 or b = -17     reject -17

The function that models the path of the second kick is y = -0.02(x - 0.30)^2 + 24

Quadratic equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k

The function that models the path of the first kick is given as

y = -0.02(x - 0.30)^2 + 18

A quadratic function is represented as

y = a(x - h)^2 + k

Where

Vertex = (h, k)

In this case, the interpretation of the vertex is

Vertex = (Horizontal distance, Maximum height)

Using the above as a guide, we have

Vertex = (30, 18)

This means that

Horizontal distance = 30

Maximum height = 18

For the second ball, we have

This means that

Horizontal distance = 30

Maximum height = 18 + 6

Evaluate

Horizontal distance = 30

Maximum height = 24

So, the function that models the path of the second kick is y = -0.02(x - 0.30)^2 + 24

Hence, the function that models the path of the second kick is y = -0.02(x - 0.30)^2 + 24

The solution of the given linear equation is (103.16 + 4x).

The given equation is;

= 9(3.2)² + 4x - 11

For finding (3.2)² = 3.2×3.2

(3.2)² = 10.24

Put the value in equation;

= 9×10.24  + 4x - 11

Multiply 9×10.24 = 92.16

Put the value;

= 92.16 + 4x + 11

Now, add the constant value

= (92.16 + 11) + 4x

= 103.16 + 4x

As, 4x is a variable part, it will not get added to the constant 103.16.
