Learning Task 3: In your answer sheet, write the letter of the correct answe

miss Akunina [59]

Answer:

a.) May or may not a polynomial function ( depends on c)

b.) Not a polynomial function.

c.) Not a polynomial function.

d.) It is a polynomial function.

Step-by-step explanation:

A polynomial function is of the form - $a_{n}x^{n} + a_{n-1} x^{n-1} + a_{n-2} x^{n-2} + .....+ a_{1}x + a_{0}$

where n is positive integer and n $\neq$ 0

a.)

P(x) = 2x³ + 32 - 4x + 4c

It may or may not a polynomial function because we did not know about the constant c.

b.)

H(x) = 4 $x^{\frac{1}{2} }$ - 3x⁴

It is not a polynomial function because $\frac{1}{2}$ is not integer.

c.)

G(x) = 2 $x^{-3}$ + 5

It is not a polynomial function because -5 is not a positive integer.

d.)

F(x) = 2x³ - 5x + 33x²

It is a polynomial function.

At the movie theater, childs admission is $6.10. Adult admission is $9.40. On Tuesday four times as many adult tickets as child

Harlamova29_29 [7]

Answer:

The number of children's tickets sold was 27

Step-by-step explanation:

Let

x ----> the number of children's tickets sold

y ----> the number of adult's tickets sold

we know that

$6.10x+9.40y=1,179.90$ ----> equation A

$y=4x$ ----> equation B

Solve the system by substitution

Substitute equation B in equation A

$6.10x+9.40(4x)=1,179.90$

solve for x

$6.10x+37.6x=1,179.90$

$43.7x=1,179.90$

$x=27$

therefore

The number of children's tickets sold was 27

Line PQ passes through the points P(-5,-13) and Q(5,17) what is the equation of line PQ in standard form

PSYCHO15rus [73]

Answer:

$3x - y = - 2$

Step-by-step explanation:

The given line PQ passes through the points P(-5,-13) and Q(5,17) .

Find the slope using the formula:

$m = \frac{y_2-y_1}{x_2-x_1}$

Plug in the points to get:

$m = \frac{17 - - 13}{5 - - 5}$

$m = \frac{30}{10}$

$m = 3$

Use the point-slope formula :

$y-y_1 = m(x - x_1)$

Substitute the point (5,17)

$y - 17 = 3(x - 5)$

Expand:

$y - 17 = 3x - 15$

The standard form is when the equation is put in the form

$ax + by = c$

Regroup the terms to get:

$3x - y = - 17 + 15$

The standard form is

$3x - y = - 2$
