Identify the zeros of the polynomial function N(x) = 1/2(x-1)(x+3)

Answers

Answer 1
Answer:

Answer:

x = - 3, x = 1

Step-by-step explanation:

Given

n(x) = (1)/(2) (x - 1)(x + 3)

To obtain the zeros, equate n(x) to zero, that is

(1)/(2) (x - 1)(x + 3) = 0

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x - 1 = 0 ⇒ x = 1

Imagine two lines intersect. How can the properties of linear pairs and vertical angles help to determine the angle measures created by the intersecting lines? Explain.

Answers

Answer:

If you know the measure of one angle in a linear pair, you can find the measure of the other because the sum of the measure of the two angles is 180 degrees. If you know the measure of one angle in a pair of vertical angles, you can find the measure of the other because they are congruent.

In February 2010, the population of the world wasapproximately 6 800 000 000 people.
Another way of writing this number is
a.6.8 × 10^8
b.6.8 × 10^9
c.68 × 10^9
d. 68 × 10^10

Answers

The correct choice is 'B'. The correct exponent is +9. In order to change 6.8 into 6,800,000,000 you have to move the decimal point 9 places in the LARGER direction.

Juan rides his horse with a constant speed of 14 km/h. How far can he travel in 2 1/2 hours?

Answers

The answer would be 35

Answer:

Step-by-step explanation:

Speed v = distance d/time t

v = 14km/h, t = 2 1/2hr = 5/2hrs

: 14 = d/(5/2)

14 = 2d/5

14 × 5 = 2d

d = (14× 5)/2

d = 35km
