Answer:

(x+1)(x+30)

Step-by-step explanation:

Area is equal to length * Width so you have to find what two expressions multiplied together equal the quadratics equation.

There are several ways to do this, but i would recommend factoring the expression. To do so, find factors of the third term that when added, equal the second term.

In this scenario

X^2 + 31x + 30

find factors of 30:

1,30

2,15

3,10

5,6

In this scenario it is clear that 1 and 30 are the two factors that equal 31

the final answer would be written as

(x+1)(x+30)

and when these two terms are multiplied out together you get your initial area

A rock is dropped off a 500-foot cliff. After 1 second the rock is traveling 32 feet per second then after 4 seconds the rock st

kozerog [31]

Answer:

A. The equation describing the relationship between speed and time is:

s = 32t

Ordered pairs of the form (speed, time) are:

(32, 1)

(64, 2)

(96, 3)

(128, 4)

B.

Using s = 32t, we have:

s = 32 * 5 = 160 feet per second

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Height of the cliff = 500 feet

Speed after one second = 32 feet per second

Speed after four seconds = 128 feet per second

2. Assume the relationship between time, t, and speed, s, is linear and write an equation describing the relationship. Use ordered pairs of the form (speed, time)

The equation describing the relationship between speed and time is:

s = 32t

Ordered pairs of the form (speed, time) are:

(32, 1)

(64, 2)

(96, 3)

(128, 4)

3. Use the equation to determine the speed of the rock 5 seconds after is dropped.

s = 32t

s = 32 * 5 = 160 feet per second

A bag holds 11 beads. 7 are red, the rest are white. Two beads are taken at random from the bag. What is the probability that on

babunello [35]

Answer:

The probability of the first draw is 100%, because the bead will be either red or white. For the second draw, a different color must be drawn.

So, if draw 1 is white, then the probability of draw 2 being red is 7/10. and if the first draw is red, then the probability of draw two being white is 5/10.
