Find zero of the poylnomial
p(x)=x-4

Answers

Answer 1
Answer: The zero of a polynomial is the value which, when placed as the variable in the equation, makes the equation equal to zero. In this case, we have the equation

p(x) = x - 4

So the zero would be the value that, when put in the place of x, makes it equal to zero. Since all that's being done on the equation is subtracting four, then all we need to do to make the equation equal to zero is to add that 4 back, since

4 - 4 = 0

And our equation would look like this:

p(x) = (4) - 4

The zero of the polynomial p(x) = x - 4 is where x = 4.
Hope that helped! =)
Answer 2
Answer: at p(x) = 0 
x-4=0 
x= 4

If the points show below are collinear, what can you conclude about the lengths AB, BC, and AC? SOMEONE PLEASE ANSWWR THIS WILL GIVE BRAINLIEST!!!!

Answers

Answer:

\sf\nAB+BC=AC

Explanation:

\sf\n\textsf{This is because the lengths of line segments AB, BC and AC are the distances}\n\textsf{between the points A,B and C respectively. And since A, B and C are collinear,}\n\textsf{these distances must add up to the total distance between A and C.}

\textsf{Here is a simple explanation:}\n\rightarrow \textsf{Suppose you are standing at point A and you want to walk on point C. You }\n\textsf{\ \ \ \ can either walk directly to point C (along line segment AC), or you can}\n\textsf{\ \ \ \ first walk to point B and then from point B to point C (along line segments}\n\textsf{\ \ \ \ AB and BC).}

\rightarrow \textsf{The total distance you walk in either case is the same. So, AB+BC=AC.}

As the marketing designer for Burger King, you are given a 4 in by 6 in logo and have been told to create an advertisement with side lengths six times larger. What is the area of your advertisement (in square feet)? [12 inches = 1 ft]A. 6 ft2
B. 36 ft2
C. 72 ft2
D. 3 ft2

Answers

If you enlarge it 6 times, then you get 24in that become 2ft and 36in that become 3ft. If the formula for calculating the area is a times b, then you have to do 2ft x 3ft and you get 6ft2

So the answer is A. 6 ft2

There are 20 cards labeled from 1 to 20 in a bag. A card is randomly selected from the bag.What is the probability of getting an even number or a 1?




9/20

11/20

1/2

3/5

Answers

Answer:

option 2=11/20  is the answer.

Step-by-step explanation:

given that there are 20 cards numbers 1,2... 20.

A card is randomly drawn.

We have to find the probability of drawing either 1 or even card.

P(drawing even card) = no of even cards/total cards = 10/20= 0.5

P(drawing one) = no of 1's/total cards = 1/20 = 0.05

P(drawing both one and even card) = 0 (since impossible)

Hence P(drawing even or one) =0.5+0.05-0

=0.55

= 11/20

Hence option 2 is the answer.

Answer : 11/20

There are 20 cards labeled from 1 to 20 in a bag. A card is randomly selected from the bag.

Total number of outcomes = 20

outcomes of an even number ={2,4,6,8,10,12,14,16,18,20}

So number of outcomes of even number = 10

outcomes of a 1 ={1}

So number of outcomes of a 1 = 1

Number of outcomes of even number and a 1 = 10+1 = 11

Probability ( any event) =number of favorable outcomes divide by total  number of outcomes

Probability (getting an even number or a 1) = (11)/(20)

A tank holding 600 liters of milk is leaking. Each week it loses 60 liters of milk. Let M be the liters of milk remaining in the tank after leaking for t weeks.Is M a linear function or an exponential function?

Why?

Answers

linear, because the tank will eventually be empty. In about 10 weeks

Final answer:

The liters of milk remaining in the tank after leaking for t weeks is represented by an exponential function. An exponential function is a mathematical function in which the independent variable appears as an exponent.

Explanation:

The function that represents the liters of milk remaining in the tank after leaking for t weeks is an exponential function. An exponential function is a mathematical function in which the independent variable appears as an exponent. In this case, the liters of milk lost each week is constant, so the amount of milk remaining in the tank is decreasing exponentially over time.

Formula for exponential decay: M = P * (1 - r)^t, where M is the amount of milk remaining, P is the initial amount of milk, r is the rate of decay, and t is the number of weeks.

In this case, the initial amount of milk, P, is 600 liters and the rate of decay, r, is 60/600 = 0.1 (10%). So the exponential function that represents the liters of milk remaining after t weeks is M = 600 * (1 - 0.1)^t.
