What is the factorization of 2x + 5x + 3?

Answers

Answer:

(2x+3)(x+1)

Step-by-step explanation:

A P E X

The factorization of the polynomial 2x² + 5x + 3 is (2x + 3)(x + 1).

What is Polynomial?

Polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables

To factorize 2x² + 5x + 3, we need to find two binomials in the form of (ax + b) and (cx + d) such that their product equals the given expression.

Firstly Multiply the coefficient of the first term (2) by the constant term (3) to get 6.

The two factors of 6 that add up to the coefficient of the middle term (5). In this case, the factors are 2 and 3.

Now Rewrite the middle term using the two factors found in the previous step. We have:

2x² + 2x + 3x + 3

We can factorize the first two terms by taking out 2x as a common factor and the last two terms by taking out 3 as a common factor. We get:

2x(x + 1) + 3(x + 1)

(2x + 3)(x + 1)

Therefore, the factorization of 2x² + 5x + 3 is (2x + 3)(x + 1).

a second sheet of paper is half as long and half as wide as the one described in part a. by what factor is its area less than the area found in part a?

Answers

The area of the second paper sheet of paper is 1/4 less than the other area

Information about the problem:

Sheet of paper figure = rectangleLength = 1/2* L₁Width = 1/2 * W₁

The formula and procedure to solve this geometry exercise is:

A(rectangle) = length * width

A(rectangle) = 1/2 L₁ * 1/2 W₁

A(rectangle) = 1/4 (L₁*W₁)

Hence, the factor of the second sheet of paper less than the first area is 1/4

What is the area?

Is the measure of the space occupied by a body bounded by an environment called perimeter, the same is expressed in units of squared side. Example: ft^2, m^2

Graph the function f(x) = x3 – 10x2 + 28x – 24 Then, write a
written description of the graph that includes all key characteristics below.
- Type of polynomial function and degree
- Domain & Range
- End behavior
- Intervals of Increasing/Decreasing
- Intervals of Positive/Negative
- Turning points (including whether it's a relative max or relative min)
- Zeros and their multiplicity (and the effect of the multiplicity on the graph)

Answers

- Cubic Function | 3-degree

- Domain & Range | Domain and Range both are all set of Real Numbers.

- End Behavior | When x approaches positive infinity, f(x) approaches positive infinity as well. When x approaches negative infinity, f(x) approaches negative infinity too.

- Intervals of Increasing/Decreasing | Increases at (-∞, 2) U (6,∞) and Decreases at (2,14/3) aka 2 < x < 14/3

- Intervals of Positive/Negative

Positive when x > 6 or (6,+∞)

Negative when 2 < x < 6 and x < 2 or (2,6) U (-∞,2)

- Turning Points are (2,0) and (14/3, -256/27)

- Zeros and Multiplicity | Factoring the polynomial as we get (x-2)(x-2)(x-6). Therefore, the zeros are multiplication of 2 and 6.

Multiplicity will affect the graph for x-axis. When the multiplicity kicks in, the graph will turn either decreasing on increasing on x-axis immediately.

Also I was plotting the graph so It might take too long.

At the shorter waterfall, water falls uninterrupted for 1552 feet before entering the river below. The height h above the river in feet of water going over the edge of the waterfall is modeled by h\left(t\right)=-16t^2+1552h(t)=−16t^2+1552, where is the time in seconds after the initial fall. Estimate the time it takes for the water to reach the river. Round your answer to the nearest tenth.

Answers

Answer:

9.9s

Step-by-step explanation:

First note that the river is on the ground level. The height of the river at the ground level is 0

Given the the height h above the river in feet of water going over the edge of the waterfall is modeled by h(t)=-16t^2+1552

When h = 0

0 = -16t^2+1552

16t^2 = 1552

t² = 1552/16

t² = 97

t = √97

t = 9.9secs

Hence the time it takes is 9.9secs to the nearest tenth
