Which of the following represents the set of possible rational roots for the polynomial shown below?

andriy [413]

You need to work out the variables of 20 (the last number) first:
1, 2, 4, 5, 10, 20
Lets call these folks "p"
At that point you need to work out the components of the main coefficient (the number before the most astounding force of x):
1
Lets call this person "q"
At that point you need to make all the conceivable divisions you can with:
±p/q
Since q is only 1, we are fortunate, so the conceivable normal roots are:
±1/1,±2/1,±4/1,±5/1.±10/1,±20/1

Find the values of b such that the function has the given maximum value <img src="https://tex.z-dn.net/?f=f%28x%29%20%3D%20-x%5E

Nostrana [21]

Answer:

b = {20, -20}

Step-by-step explanation:

Given function:

f(x) = -x² + bx - 65 with maximum value of 35

To find

The value of b

Solution:

Maximum value is obtained at vertex as a < 0

Vertex coordinate of x is:

x = -b/2a = -b / -2 = 1/2b

Solving for b:

35 = - (1/2b)² + b(1/2b) - 65
- 1/4b² + 1/2b² = 100
1/4b² = 100
b² = 400
b = √400
b = ± 20

valkas [14]

Part (a)

$\frac{1}{10}+\frac{3}{10}=\frac{4}{10}=\boxed{\frac{2}{5}}$

Part (b)

$200\left(\frac{2}{5} \right)=\boxed{80}$

Help please!!! can you show me how to do this??

IrinaK [193]

$\frac{3x - 2}{x^{2} - 2x - 3} - \frac{1}{x - 3} = \frac{3x -2}{(x + 1)(x - 3)} - \frac{1}{x - 3} = \frac{3x - 2}{(x + 1)(x - 3)} - \frac{1(x + 1)}{(x + 1)(x - 3)} = \frac{3x - 2}{(x + 1)(x - 3)} - \frac{x + 1}{(x + 1)(x - 3)} = \frac{2x - 3}{(x + 1)(x - 3)}$

The number of cars sold weekly by a new automobile dealership grows according to a linear growth model. The first week the deale

Sladkaya [172]

Answer:

Recursive Formula, Pₙ=Pₙ₋₁+2

Explicit Formula, Uₙ=4+2n

12 cars

Step-by-step explanation:

In Week 1, the dealer sold six cars, P₀=6

In Week 2, the dealer sold 8 cars, P₁=8

The difference in car sales between the first and second week is 2.

Therefore, for the (n+1)th week, the Recursive Formula is Pₙ=Pₙ₋₁+2

This is an arithmetic progression where the:

First term, a=6

Common difference, d =2

The nth term of an A.P. is given by Uₙ=a+(n-1)d.

The Explicit Formula, Uₙ=6+2(n-1)

=6+2n-2=4+2n

In the fourth week, U₄=4+2(4)=4+8=12

12 cars will be sold in the fourth week
