Equation with angles can some please answer

Gelneren [198K]

Answer:

Step-by-step explanation:

Parallel lines. A & B are corresponding angles and corresponding angles are equal.

∠A = ∠B

8x - 8 = 5x + 25

Add 8 to both sides

8x - 8 + 8 = 5x + 25 + 8

8x = 5x + 33

Subtract 5x from both sides

8x - 5x = 5x +33 - 5x

3x = 33

Divide both sides by 3

3x/3 = 33/3

x = 11

∠B = 5x + 25 = 5*11 + 25 = 55 +25 = 80

∠B = 80°

Use math notation to describe the following sequence: <br> 1, -1, 1, -1,...

Veseljchak [2.6K]

Answer:

The math notation to the given sequence is $a_n=(-1)^{n+1}$ for n=1,2,3,... is verified and it is true

Step-by-step explanation:

Given sequence is 1,-1,1,-1,...

Let $a_1=-1,a_2=1,a_3=-1,a_4=-1,...$

To find the math notation for the given sequence :

$a_n=(-1)^{n+1}$ for n=1,2,3,... verify that it is true or not

Put n=1 in the above equation we get

$a_1=(-1)^{1+1}$

$=(-1)^2$

Therefore $a_1=1$

Put n=2 in the $a_n=(-1)^{n+1}$ equation we get

$a_2=(-1)^{2+1}$

$=(-1)^3$

Therefore $a_2=-1$

Put n=3 in the $a_n=(-1)^{n+1}$ equation we get

$a_3=(-1)^{3+1}$

$=(-1)^4$

Therefore $a_3=1$

and so on

Therefore the math notation to the given sequence is $a_n=(-1)^{n+1}$ for n=1,2,3,... is verified and it is true

A model predicts the profit, p of a company as p(x) = x3 – 3x2 – 16x + 48, where p is in thousands of dollars and x is number of

zavuch27 [327]

The first step is to determine the zeros of p(x).
From the Remainder Theorem,
p(a) = 0 => (x-a) is a factor of p(x), and x=a is a zero of p(x).

Try x=3:
p(3) = 3^3 - 3*3^2 - 16*3 + 48 = 27 - 27 - 48 + 48 = 0
Therefore x=3 is a zero, and (x-3) is a factor of p(x).

Perform long division.
x² - 16
-------------------------------------
x-3 | x³ - 3x² - 16x + 48
x³ - 3x²
-----------------------------------
- 16x + 48
- 16x + 48

Note that x² - 6 = (x+4)(x-4).

Therefore the complete factorization of p(x) is
p(x) = (x-3)(x+4)(x-4)

To determine when p(x) is negative, we shall test between the zeros of p(x)
