Round each number to the specified place

1 answer:

3 0

If the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up (+1).

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down (no change).

$207,689\approx210,000\\\\507,378\approx1,000,000\\\\3,422,087\approx3,422,000\\\\19,499,890\approx19,000000$

Answer:

+ 10 and + 7

Step-by-step explanation:

Given

2x² + 7x + 5

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.

product = 2 × 5 = + 10 and sum = + 7

Consider functions f and g

alexdok [17]

Answer:

Step-by-step explanation:

$f(x) = \dfrac{x - 16}{x^2 + 6x - 40}$

$g(x) = \dfrac{1}{x + 10}$

$f(x) + g(x) = \dfrac{x - 16}{x^2 + 6x - 40} + \dfrac{1}{x + 10}$

$f(x) + g(x) = \dfrac{x - 16}{x^2 + 6x - 40} + \dfrac{(x - 4)}{(x + 10)(x - 4)}$

$f(x) + g(x) = \dfrac{x - 16 + x - 4}{x^2 + 6x - 40}$

$f(x) + g(x) = \dfrac{2x - 20}{x^2 + 6x - 40}$

any triangle may be rotated and translated so that one vertex is at the origin and another vertex is on the positive x-axis. Wha

Aloiza [94]

Since line segment DE is a midline of the triangle joining the midpoints of sides AB and AC, thus by the triangle midsegment theorem, line segment DE is parallel to side BC and is half the length of line segment BC.

The triangle mid-segment theorem states that the mid-segment of a triangle, which joins the midpoints of two sides of a triangle, is parallel to the third side of the triangle and half the length of that third side of the triangle.

Therefore, the relationship between the length of DE and the length of BC is that the length of DE is half the length of BC.
