Answer:

[tex]\boxed {21}[/tex]

Step-by-step explanation:

Find [tex]g(5)[/tex]:

[tex]g(x) = x^{2} - 4[/tex]

-Apply [tex]5[/tex] for variable [tex]x[/tex] to the equation:

[tex]g(5) = (5)^{2} - 4[/tex]

-Solve the expression:

[tex]g(5) = (5)^{2} - 4[/tex]

[tex]= 25 - 4[/tex]

[tex]= \boxed {21}[/tex]

Therefore, the final answer is [tex]21[/tex].

Answer:

96.512 °F < x < 591.242 °F

Step-by-step explanation:

We are given;

Melting point = 35.84 °C

Boiling point = 310.69 °C

Now, we are given that formula to convert °C to °F is;

°C = (5/9)°F

Thus if the temperature in Fahrenheit is x, then;

Melting point is; 35.84 °C = (5/9)x°F - "32"

x = ((9 × 35.84)/5) + 32

x = 96.512 °F

Similarly, for Boiling point;

Boiling point is;

310.69 °C = (5/9)x°F - "32"

x = ((9 × 310.69)/5) + 32

x = 591.242 °F

Now, we are told that matter is in its liquid form when it is between melting and boiling point.

Thus, range of x in inequality form is;

96.512 °F < x < 591.242 °F

Step-by-step explanation:

Answer:

The coordinates of the focus are [tex]F(x,y) = (-1,0)[/tex] anf the equation of the directrix is [tex]x = 1[/tex], respectively.

Step-by-step explanation:

Let be [tex]y^{2} = -4\cdot x[/tex], which represents a parabola with a horizontal axis of symmetry. To find the location of the focus and to determine the equation of the directrix we must find the distance between focus and vertex ([tex]p[/tex]), dimensionless, a value than can be extracted from the following definition:

[tex](y-k)^{2} = 4\cdot p \cdot (x-h)[/tex] (Eq. 1)

Where:

[tex]x[/tex] - Independent variable, dimensionless.

[tex]y[/tex] - Dependent variable, dimensionless.

[tex]h[/tex], [tex]k[/tex] - Coordinates of the vertex, dimensionless.

By direct comparison, we get the following coincidences:

[tex]h = 0[/tex]

[tex]k = 0[/tex]

[tex]4\cdot p = -4[/tex] (Eq. 2)

From (Eq. 2) we get that distance between focus and vertex is:

[tex]p = -1[/tex]

Which is consistent with the fact parabola has an absolute maximum.

Now, the location of the focus is:

[tex]F(x,y) = (h+p, k)[/tex] (Eq. 3)

If know that [tex]h = 0[/tex], [tex]k = 0[/tex] and [tex]p = -1[/tex], coordinates of the focus is:

[tex]F(x, y) = (0-1, 0)[/tex]

[tex]F(x,y) = (-1,0)[/tex]

And the equation of the directrix is represented by:

[tex]x = -p[/tex] (Eq. 4)

([tex]p = -1[/tex])

[tex]x = 1[/tex]

The coordinates of the focus are [tex]F(x,y) = (-1,0)[/tex] anf the equation of the directrix is [tex]x = 1[/tex], respectively.

Answer:

The general formula for this parabola is y2 = 4px.

Therefore, the value of p is  

✔ –1

.

The coordinates of the focus are  

✔ (–1,0)

.

The equation of the directrix is  

✔ x = 1

The value of the function f(n)=5n+8 for f(4) will be 28.

A function is defined as the expression that set up the relationship between the dependent variable and independent variable.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given function is f(n)=5n+8. The value of the function at equal to 4 will be calculated as below:-

f(n)=5n+8

f(4) = ( 5 x 4 + 8 )

f(4) = 20 + 8

f(4) = 28

Therefore, the value of the function f(n)=5n+8 for f(4) will be 28.

Answer:

A: 180 -45

Step-by-step explanation:

Since it is a straight angle, it will equal 180 degrees. Since 45 is already taken, u would subtract it from 180.

180-45=135

thus, your answer is 180-45
