Answer:

  1.  value is 0; x-3 is a factor . . . . . . . . . . . . . .third choice

  2.  evaluates at x = -1; remainder is -11 . . . . first choice

Step-by-step explanation:

Dividing f(x) by (x -a) gives ...

  f(x)/(x -a) = g(x) +r/(x -a) . . . . some quotient and a remainder r

If we multiply this expression by (x -a), we see ...

  f(x) = (x -a)g(x) +r

so

  f(a) = (a -a)g(a) +r . . . . . evaluate the above equation at x=a

  f(a) = 0 +r

  f(a) = r . . . . . . . . . a statement of the remainder theorem

If r=0, then x-a is a factor of f(x) = (x-a)g(x).

___

1. We have "a" = 3, and f(3) = 0. Therefore (x-3) is a factor.

__

2. We have "a" = -1, and f(-1) = -11. Therefore the remainder from division by (x+1) is -11.

Consumer Math TestYou borrow $13,000 to buy a car. You borrow the money for 4 years and the interest rate is 2.5%. How much inte
enot [183]

Answer:

You will pay $1,300 in interest.

The final price of the car is of $14,300

Step-by-step explanation:

Simple interest formula:

I=P\ast r\ast t

In which:

I is the interest

P is the principal(initial value of the investment, amount borrowed,...)

r is the interest rate, as a decimal

t is the time, in years.

In this question:

Borrow $13,000, so P = 13000

4 years, so t = 4

Interest rate of 2.5%, so r = 0.025

I=13000\ast0.025\ast4=1300

You will pay $1,300 in interest.

Final price of the car:

Principal plus interest.

T=P+I=13000+1300=14300

The final price of the car is of $14,300

What shows the correct substitution of the values a,b, and c from the equation 0=-3x^2-2x+6
Arlecino [84]

When dealing with a quadratic equation, you usually assign the following name to the coefficients of the variables:

ax^2+bx+c=0

So, a is the coefficient of x^2, b is the coefficient of x and c is the constant term.

In your case, the coefficient of x^2 is -3, so a=-3

The coefficient of x is -2, so b = -2

The constant term is 6, so c = 6

We know for the problem that the performer earned $120 at a performance where 8 people attend. We also know that he u<span>ses 43% of the money earned to pay the costs involved in putting on each performance, so we need to find the 43% of $120. To do that, we are going to divide 43% by 100%, and then multiply it by $120:
</span>\frac{43}{100}*120=51.6
Now we know that the performer uses $51.6 of $120 to pay the costs involved in putting on each performance. The only thing left to find his profits is subtract $51.6 from $120:
120-51.6=68.4

We can conclude that the performer makes a profit of $68.4 when 8 people attend his performance.
