O 5 and 3

O 0 and 5

Answers

Answer:

-3 and -5

Step-by-step explanation:

The zeros are where the line touches the x-axis

From the graph we can see that the line touches those points.

You can also determine it from the equation because the equation is in factored form, which is (x-r1)(x-r2)

Remember that it is minus so although it is +3 and +5 the actual zero is negative!!

-5 and -3 because it’s a parabola so whichever two or more is on the x-axis will be your zeros

1. The nominal rate on Sandra's loan is 7.125%. If the interest is compounded monthly, what rate of

interest is Sandra actually paying? (use the formula)

Answers

Answer:

She is actually paying a rate of 7.36% of interest.

Step-by-step explanation:

The real interest rate, as a decimal, is given by:

[tex]I = (1 + \frac{r}{n})^{n}[/tex]

In which r is the interest rate and n is the number of compoundings during an year.

The nominal rate on Sandra's loan is 7.125%, compounded monthly:

This means that [tex]r = 0.07125, n = 12[/tex]

[tex]I = (1 + \frac{0.07125}{12})^{12} = 1.0736[/tex]

As a percentage: 1.0736*100 = 107.36% - 100% = 7.36%

She is actually paying a rate of 7.36% of interest.

a Quadratic pattern has a second term equal to 1,a third term equal to-6 and a fifth term equal to -14

Quadratic sequences

A sequence is a set of numbers that are connected in some way. In this section we will look at quadratic sequences where the difference between the terms changes.

Quadratic sequences

If the difference between the terms changes, this is called a quadratic sequence.

If you use the formula n2 + n to make a sequence, it means that:

When n = 1 you get 12 + 1 = 2
When n = 2 you get 22 + 2 = 6
When n = 3 you get 32 + 3 = 12
When n = 4 you get 42 + 4 = 20
- giving the sequence 2, 6, 12, 20.

Here, the differences between terms are not constant, but there is still a pattern.

- the first differences increase by 2 each time
- the second increases by 2

When the second difference is constant, you have a quadratic sequence - ie, there is an n2 term.

Learn these rules:
If the second difference is 2, you start with n2.
If the second difference is 4, you start with 2n2.
If the second difference is 6, you start with 3n2.
Another definition for Quadratic sequence

A quadratic sequence is a sequence of numbers in which the second difference between each consecutive term is constant. This called a common second difference.

Wilkins FreemanIn about half an hour Joe Dagget came. She heard his heavy step on the walk and rose and took off her pink and white apron. Under that was still anotherwhite linen with a little cambric edging on the bottom; that was Louisa's company apron. She never wore it without her calico sewing apron over it unless she had a guest. She had barely folded the pink and white one with methodical haste and laid it in a table drawer when the door opened and Joe Dagget entered. He seemed to fill up the whole room. A little yellow canary that had been asleep in his green cage at the south window woke up and fluttered wildly, beating his little yellow wings against the wires. He always did so when Joe Dagget came into the room."Good-evening," said Louisa. She extended her hand with a kind of solemn cordiality."Good-evening, Louisa," returned the man, in a loud voice.She placed a chair for him, and they sat facing each other, with the table between them. . . .Presently, Dagget began fingering the books on the table. There was a square red autograph album and a Young Lady's Gift-Book, which had belonged to Louisa's mother. He took them up one after the other and opened them; then laid them down again, the album on the Gift-Book.Louisa kept eyeing them with mild uneasiness. Finally she rose and changed the position of the books, putting the album underneath. That was the way they had been arranged in the first place.Dagget gave an awkward little laugh. "Now what difference did it make which book was on top?" he said.Louisa looked at him with a deprecating smile. "I always keep them that way," she murmured."You do beat everything," said Dagget, trying to laugh again. His large face was flushed.Adapted from Mary E. Wilkins Freeman's "A New England Nun," 1899.
