Answer:

P(x) = -0.4 $x^{3}$ + 100 $x^{2}$ - 300 $x$ + 500

Step-by-step explanation:

C(x) = 600 $x^{2}$ + 300 $x$

R(x) = -0.4 $x^{3}$ + 700 $x^{2}$ - 600 $x$ + 500

P(x) = R(x) - C(x)

(-0.4 $x^{3}$ + 700 $x^{2}$ - 600 $x$ + 500) - (600 $x^{2}$ + 300 $x$ )

= -0.4 $x^{3}$ + 100 $x^{2}$ - 300 $x$ + 500

This should be the answer.

Answer:

c. y = -35*x + 105

Step-by-step explanation:

Lo que demos hacer es calcular los puntos cuando x = 0 y cuando x = 3, es decir el inicio y el fin del recorrido.

Cuando x es igual 0, y = 105, por lo tanto, la función sería:

y = A*x + 105

Cuando x = 3, y = 0, por lo tanto:

0 = 3*A + 105

resolvemos para A:

3*A = -105

A = -105/3

A = -35

Por lo tanto la función es:

y = -35*x + 105

es decir, la opción c.

Aya = a1 + (n - 1)d

Alenkasestr [34]

Answer:

The 26th term of an arithmetic sequence is:

$a_{26}=67$

Hence, option A is true.

Step-by-step explanation:

Given

a₁ = -33

d = 4

An arithmetic sequence has a constant difference 'd' and is defined by

$a_n=a_1+\left(n-1\right)d$

substituting a₁ = -33 and d = 4 in the nth term of the sequence

$a_n=-33+\left(n-1\right)4$

$\:a_n=-33+4n-4$

$a_n=4n-37$

Thus, the nth term of the sequence is:

$a_n=4n-37$

now substituting n = 26 in the nth term to determine the 26th term of the sequence

$a_n=4n-37$

$a_{26}=4\left(26\right)-37$

$a_{26}=104-37$

$a_{26}=67$

Therefore, the 26th term of an arithmetic sequence is:

$a_{26}=67$

Hence, option A is true.
