Scientific notation is used to write really large numbers, or really small numbers using less digits. For example:

1. Earth's distance from the sun 150,000,000 kilometers. We can rewrite this in scientific notation as 1.5 x $10^{8}$

2. The length of a skin cell is 0.00003 meters. We can rewrite this in scientific notation as 3.0 x $10^{-5}$

3. The world population is about 7,000,000,000. We can rewrite this in scientific notation as 7 x $10^{9}$

a(t)=(t−k)(t−3)(t−6)(t+3) is a polynomial function of t, where k is a constant. Given that a(2)=0 , what is the absolute value o

tiny-mole [99]

First, we need to define k because it is a missing zero;

Knowing that a(2)=0;

a(t)=(t-k)(t-3)(t-6)(t+3)
a(2)=(2-k)(2-3)(2-6)(2+3)=0
(2-k)(-1)(-4)(5)=0
(2-k)(20)=0
(2-k)=0/20
2-k=0
2=k

Therefore, the final equation is a(t)=(t-2)(t-3)(3-6)(t+3) with the zeros being (2, 3, 6, -3)

Hope I helped :)

The path of a breaching ocra whale can be modeled by the function k(x) = x^2 - 2x - 8, where x is the time elapsed in seconds un

____ [38]

Answer:

The time duration of the ocra whale spends under water is 4 seconds

Step-by-step explanation:

The equation that model the path of the ocra whale is presented as follows;

k(x) = x² - 2·x - 8

Where;

x = The time elapsed in seconds under water

k(x) = The height in feet below water

Therefore, the point where the ocra whale enters the water, k(x) = 0

At the point of submerging below the water surface, we have;

k(x) = 0 = x² - 2·x - 8

Factorizing the quadratic equation gives;

0 = x² - 2·x - 8 = (x - 4)·(x + 2)

Therefore, when k(x) = 0, either;

(x - 4) = 0, which gives, x = 4

(x + 2) = 0, which gives, x = -2

Given that 'x' represent the time, the time elapsed while the whale is under water, x = 4 seconds
