Answer:600

Step-by-step explanation:

The 6 is in the hundreds place, so you in order to round it you would look at the 4. Since 4 is a a number less than 5 you round down. That would mean 600 instead of 700.

Answer: 600

Step-by-step explanation: To round 649 to the nearest hundred, we first find the digit in the rounding place which in this case is the 6 in the hundreds place.

To decide whether to round up or down, we look at the digit to the right of the 6 which is 4.

According to the rules of rounding, if the digit to the right of the rounding place is less than 5, we round down.

So in this problem, since 4 is less than 5, we round down.

This means that the 6 in the hundreds place stays the same and all digits to the right if 6 become 0.

So 649 rounded to the nearest hundred is 600.

Read the poem.

The Courage That My Mother Had  

by Edna St. Vincent Millay.

The courage that my mother had

Went with her, and is with her still:

Rock from New England quarried;

Now granite in a granite hill.

The golden brooch my mother wore

She left behind for me to wear;

I have no thing I treasure more:

Yet, it is something I could spare.

Oh, if instead she’d left to me

The thing she took into the grave!—

That courage like a rock, which she

Has no more need of, and I have.

In "The Courage That My Mother Had," what is the meaning of the line Now granite in a granite hill?  

The speaker wants to be more like her mother.

The speaker's mother has passed away.

The speaker's mother has turned to stone.

The speaker is visiting her mother's home.

How many distinct positive integer-valued solutions exist to the equation (x2 - 7x + 11)(x2 - 13x + 42) = 1
Anna35 [415]

Answer:

The given equation has TWO positive integer valued solutions, {6, 7}

Step-by-step explanation:

Here we are given two trinomial factors, each of which needs to be set equal to zero and in each case the resulting quadratic equation solved.

(x^2 - 7x + 11) has the coefficients {1, -7, 11}, and so the discriminant of this quadratic is b^2 - 4(a)(c), or 49 - 4(11), or 5.

Because this discriminant is positive, we know immediately that this quadratic has two real, unequal roots involving √5 (NO integer roots).

Next we focus on (x^2 - 13x + 42).  The discriminant is b^2 - 4(a)(c), or

169 - 168, or 1.  Again we see that there are two real, unequal roots:

      +13 ± √1                  +13 ± 1

x = ---------------  or  x = -------------

             2                            2

OR x = 14/2 = 7 (integer) or x = 12/2 = 6 (integer).

The given equation has TWO positive integer valued solutions, {6, 7}
