Answer:

Option B

A factor is x-1

Step-by-step explanation:

To find the factors of the polynomial, we will have to look for the roots of the polynomial.

Whenever a polynomial is plotted on a graph, it is important to note that the root of the polynomial refers to the points where the line cuts the x-axis.

From our curve given in the question, the roots of the polynomial are:

x = 1 and x = 6

Let us consider the first root

x = 1

from this, we can get x-1 =0

We will have to take only this as our answer because we are looking for only one of the factors.

Hence, a factor is x-1 and also our correct answer.

What is quotient and remainder

butalik [34]

Hi there, a quotient is the answer of a division problem. For example, 2÷2=1, 1 is the quotient. A remainder is a number that is left over in a division problem. For example, 7÷2=3 R1, R1 is remainder of 1.

A television game show has 12 doors, of which the contestant must pick 3. Behind 3 of the doors are expensive cars, and behind

almond37 [142]

The probability that the contestant wins at least one car is 3/5.

<h3>What is the probability?</h3>

Probability refers to a possibility that deals with the occurrence of random events.

The probability of all the events occurring need to be 1.

For 1 car, we consider two possible outcomes:

P(1 car) = 2/6 x 4/5 + 4/6 x 2/5

P(1 car) = 8/15

For no car in either door

P(no car) = 4/6 x 3/5

P(no car) = 2/5

The probability that the contestant wins at least one car is the sum of the probability of one car and the probability of two cars:

P(2 cars) = 2/6 x 1/5

= 1/15

P(1 car) + P(2 cars) = 8/15 + 1/15

= 3/5

A farmer is tracking the number of soybeans his land is yielding each year. He finds that the function f(x) = −x2 + 20x + 100 mo

labwork [276]

Answer:

The farmer should expect to LOSE 10 pounds of soybeans per acre per year

Step-by-step explanation:

f(x)=-x^2 + 20x + 100

just find how many soybeans his land will yield (per acre) after 10 and 20 years:

After 10: 200 pounds of soybeans/acre

After 20: 100 pounds of soybeans/acre

Because 10 years have passed and they lost 100 pounds of soybean production per acre, the farmer should expect to lose 10 pounds of soybeans per acre per year (-10 pounds of soybeans per acre/year)

Brandon is playing hide-and-seek with Katy and Tony. Katy is hiding 63 feet south of Brandon, and Tony is hiding due east of Kat

sergij07 [2.7K]

Answer:

60 feets

Step-by-step explanation:

Given that :

Using Pythagoras rule :

Hypotenus = sqrt(Adjacent^2 + opposite^2)

From the attached picture :

x² = 87^2 - 63^2

x^2 = 7569 - 3969

X^2 = 3600

Take the square root of both sides :

X = sqrt(3600)

X = 60 feets

Hence, Katy and Tony are 60 feets apart
