Fourth degree and a single zero of -3

Mathematics
1 answer:
Darya [45]3 years ago
3 0

The degree of a polynomial is the highest power of the polynomial.

The polynomial is \mathbf{P(x) = (x + 3)^4}

The degree is given as:

\mathbf{n = 4}

The zero is given as:

\mathbf{x = -3}

Add 3 to both sides

\mathbf{x  + 3= 0}

From the question, we understand that the polynomial has a single zero.

So, the polynomial is:

\mathbf{P(x) = (x + 3)^n}

Substitute 4 for n

\mathbf{P(x) = (x + 3)^4}

Hence, the polynomial is \mathbf{P(x) = (x + 3)^4}

Kazeer [188]

The question is incomplete, the complete question is;

A factory produces 1,250,000 toys each year. The number of toys is expected to increase by about 150% per year. Which model can be used to find the number of toys being produced, n (in millions), in t years?

A. n= 2.5(1.5)/t, t cannot = 0

B. n= 1.5t^2 + 1.25

C. n= 1.5t + 1.25

D. n= 1.25(2.5^t)

Answer:

D. n= 1.25(2.5^t)

Step-by-step explanation:

This is an exponential growth problem. In mathematics, for an exponential growth problem;

P = Po(1 + r)^t

Where;

P= amount at time t

Po =initial amount

r= rate

t= time

In the context of the question we have;

n= 1.25(1 + 150/100)^t

n= 1.25(2.5)^t

Answer:

d

Step-by-step explanation:

Step-by-step explanation:

Using Pythagoras' identity on the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

AB² = 7² + 4² = 49 + 16 = 65 ( take the square root of both sides )

AB = \sqrt{65} → D

El Generico public high school got a new flagpole. But they completely forgot to buy a cord and NO ONE knows how tall the flagpo
Pie
In measurement problems such as these, we can use proportional relationships to determine the length or measure of triangular sides.This works because the two figures are similar. Our proportion is going to have a variable since we do not know the height of one of the flagpoles. It will be set up as such: 

\frac{5}{8} = \frac{x}{32}

We cross multiply, then divide to solve this proportion.

32 x 5 = 160. 

160/8 = 20. 

This means the height of the flagpole is 20 feet high. To fit the height of the flag pole, the cord the school should buy for the flagpole should be 20 feet long.
