What is the completely factored form of t4 − 16?

Mathematics
1 answer:
Mashcka [7]3 years ago
7 0

we know that

A difference of squares problem can be factored as follows:

a^{2}-b^{2} =(a+b)(a-b)

in this problem we have

t^{4}-16

Applying difference of squares

t^{4}-16=(t^{2}-4)( t^{2}+4)

the term

(t^{2}-4)=(t+2)(t-2)

substitute

(t^{2}-4)( t^{2}+4)=(t+2)(t-2)( t^{2}+4)

therefore

<u>the answer is</u>

(t+2)(t-2)( t^{2}+4)

For the graph of the function, identify the axis of symmetry, vertex and the formula for the function.
snow_tiger [21]
We know that this is a parabola, as the equation is denoted by the x^2 term.

We can see that the symmetry is seen at the point -0.5, therefore making the axis of symmetry the vertical line -0.5.

The vertex is found in quadrant three. In other words, it will shift by a negative value both horizontally and vertically. The vertex is therefore (-0.5, -0.5).

We can verify this in the equations by using the formula (-b/2a) to find the vertex. The only quadratic equation that satisfies this is -2x^2 + 2x -1.

To sum it up, the answers are:

-2x^2 + 2x - 1.

AoS: x = -0.5

Vertex: (-0.5, -0.5).

Bamboo plants grow rapidly. A bamboo plant is 130 inches tall. Tomorrow it will be 143 inches tall, the next day it will be 156
tensa zangetsu [6.8K]
An arithmetic sequence has a common difference.
143 - 130 = 13
156 - 143 = 13
169 - 156 = 13
The common difference is 13.

a1 = 130
a2 = 130 + 13
a3 = 130 + 2 * 13
a4 = 130 + 3 * 13
...
an = 130 + (n - 1) * 13

an = 130 + 13(n - 1)

an = 130 + 13n - 13

an = 117 + 13n

an = 13n + 117

belka [17]

Answer: Mrs.Buller collects a 500-ml sample of seawater for her chemistry class, and it has 1.94% of chlorine, we have to determine the amount of chlorine in the sample:

\begin{gathered} C=\frac{1.94}{100}\times500=9.7ml \\ C=9.7ml \end{gathered}

Therefore the chlorine content in 500ml of water is 9.7ml.
