The equation of the car is given by the equation,
x(t) = 2.31 + 4.90t² - 0.10t⁶
If we are going to differentiate the equation in terms of x, we get the value for velocity.
dx/dt = 9.8t - 0.6t⁵
Calculate for the value of t when dx/dt = 0.
dx/dt = 0 = (9.8 - 0.6t⁴)(t)
The values of t from the equation is approximately equal to 0 and 2.
If we substitute these values to the equation for displacement,
(0) , x = 2.31 + 4.90(0²) - 0.1(0⁶) = 2.31
(2) , x = 2.31 + 4.90(2²) - 0.1(2⁶) = 15.51
Thus, the positions at the instants where velocity is zero are 2.31 and 15.51 meters.

Answer:
This is because animals do not need to store as much water as plants.
Explanation:
Animals generally have smaller vacuoles than plants. Plants have large vacuoles that can occupy a large portion of their cell (up to 30 percent). The major function of the vacuole is to store water and maintain cell turgidity and pressure against the cell wall.
Animals on the other hand do not have a rigid cell wall, rather, they have a flexible cell membrane. As a result of this, they do not need to store water in vacuoles.
Answer:
In chemistry, a nonmetal (or non-metal) is a chemical element that mostly lacks the characteristics of a metal. Physically, a nonmetal tends to have a relatively low melting point, boiling point, and density. ... Metalloids such as boron, silicon, and germanium are sometimes counted as nonmetals
