Answer:

the third option, lengths of opposite sides are equal.

Step-by-step explanation:

for edg users I just took the test.

The absolute value function can be expressed as a piecewise function. The correct absolute value function that represents the given graph is f(x) = |x + 2| - 1. The vertex of the graph is (-2, -1) and the line of symmetry is x = 2.

a) Rewrite the function as a piecewise function: The absolute value function can be expressed as a piecewise function by considering the different intervals where the expression inside the absolute value changes its sign. In this case, the function may be written as:
[tex]f(x) = \begin{cases} -(x + 2) - 1, & \text{if } x \leq -2 \\ (x + 2) - 1, & \text{if } x > -2 \end{cases}[/tex]

b) Which of the following absolute value functions represents the graph: To determine which of the given options matches the graph, we compare the expressions inside the absolute values with the piecewise function from part (a). In this case, the correct match is f(x) = |x + 2| - 1.

c) Describe the relationship between the absolute value function and the vertex of the graph: The vertex of the absolute value function f(x) = |x + h| + k is (-h, k). In this case, the vertex is (-2, -1). This means that the graph has been shifted two units to the left and one unit down.

d) What is the line of symmetry of the graph: The line of symmetry for an absolute value function of the form f(x) = |x + h| + k is the vertical line x = -h. In this case, the line of symmetry is x = -(-2) = 2. The graph is symmetric with respect to the line x = 2.

Answer:

105.2 ft²

Step-by-step explanation:

The diameter of the base of the cone is 6 ft which means its radius is:

r = d / 2 = 6 / 2 = 3 ft

Its height, h, is 7.6 ft.

The surface area of a cone is given as:

A = pi * r(r + √(h² + r²))

Therefore:

A = pi * 3(3 + √(7.6² + 3²))

A = pi * 3(3 + √(57.76 + 9))

A = pi * 3(3 + √(66.76))

A = 9.42(3 + 8.17)

A = 9.42 * 11.17 = 105.2214 ft²

Approximating to the nearest 10th, the surface area of the cone is 105.2 ft².

Answer:

Length = 14 inches

Width = 3 inches

Step-by-step explanation:

length * width = area

(x + 8 ) (x - 3) = 42

Use FOIL method

x*x  - x*3 + 8*x - 8*3 = 42

x² -3x + 8x - 24 = 42

x² + 5x - 24 - 42 = 0

x² + 5x - 66 = 0

Sum = 5

Product  = 66

Factors = 11 , (-6)

x²  + 5x -66 = 0

x² + 11x - 6x - 6*11 =0

x(x + 11) - 6(x + 11) = 0

(x + 11) (x -6) = 0

x + 11 is ignored because length and width will not have negative value.

x - 6 = 0

x = 6

Length = x + 8 = 6 + 8 = 14 inches

Width = x - 3 = 6 - 3 = 3 inches

Answer: amplitude = 6.5

Step-by-step explanation:

The amplitude of a function is the maximum displacement from the from a fixed point or from the origin.

From the graph, you take the initial position of the object from the broken red line which is equal to 3.3 at the Y axis.

The peak or the maximum value = 9.8

Amplitude = 9.8 - 3.3 = 6.5

The maximum displacement is at Y axis

Answer: (6, -1)

Step-by-step explanation:

Given that point (3,1) satisfies the function f(×).  From the equation

g(x)=-2f(x/2)+1

x/2 = 3

x = 6

Substitute the 1 for f(x/2)

g(x) = -2(1)+1

g(x) = -2 + 1 = -1

The point that would satisfy g(x)=-2f(x/2)+1 is (6, -1)

Answer:

[tex] \sigma^2 = 3^2 \frac{10-1}{10}= 8.10[/tex]

Step-by-step explanation:

For this case we have a sample of n =10 and we have the following statistics:

[tex]\bar X = 37.3 , s= 3[/tex]

And we want to estimate the population variance. We need to remember that the population variance is given by this formula:

[tex]\sigma^2 =\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n}[/tex]

And the sample variance is given by:

[tex] s^2 =\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}[/tex]

And we can find a formula for the population variance in terms of the sample deviation like this:

[tex] \sigma^2 = s^2 \frac{n-1}{n}[/tex]

And replacing we got:

[tex] \sigma^2 = 3^2 \frac{10-1}{10}= 8.10[/tex]

Answer:

Let us say the domain in the first case, has the numbers. And the co-domain has the students, .

Now for a relation to be a function, the input should have exactly one output, which is true in this case because each number is associated (picked up by) with only one student.

The second condition is that no element in the domain should be left without an output. This is taken care by the equal number of students and the cards. 25 cards and 25 students. And they pick exactly one card. So all the cards get picked.

Note that this function is one-one and onto in the sense that each input has different outputs and no element in the co domain is left without an image in the domain. Since this is an one-one onto function inverse should exist. If the inverse exists, then the domain and co domain can be interchanged. i.e., Students become the domain and the cards co-domain, exactly like Mario claimed. So, both are correct!

form triangle

In order for the points to form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side. In this case, 5 + 6 = 11 > 2, 5 + 2 = 7 > 6, and 6 + 2 = 8 > 5. Therefore, the points form a triangle.

Answer:

No.

Step-by-step explanation:

For area you will multiply 12x12=144.

For the perimeter you will add 12+12=24

I hope this helps!

Answer:

Angle A

Step-by-step explanation:

Angle A is the opposite angle to the longest side of the triangle.

Because the angle is larger, the side opposite of it should be long enough to connect to the two other sides.

Step-by-step explanation:

The given value is 8.03 X 10^-8, which is already in scientific notation. None of the provided alternatives exactly match the given value. The closest number to the given value is 9.71 X 10^-8.

The given value is 8.03 X 10^-8. This is already in scientific notation, where a number is represented as a decimal number between 1.0 and 10.0, multiplied by a power of 10. Therefore, it is equivalent to itself. If you would look for the equivalent among the options you have, none of them would match exactly the given value. The number that comes closest to your value from those given is 9.71 X 10^-8, but remember, these two are not exactly the same.
