Answer:
2nd option
Step-by-step explanation:
given an exponential function in the form y = a
to find a and b use the coordinate points it passes through
using (0, 4 ) , then
4 = a [ = 1 ] , that is
a = 4 , so
y = 4
using (2, 100 )
100 = 4b² ( divide both sides by 4 )
25 = b² ( take the square root of both sides )
= b , that is
b = 5
then exponential function is
y = 4 .

Answer:
dy/dt = 8
Step-by-step explanation:
y = 2x^3 -4x
dy/dt = 2 * 3x^2 dx/dt -4 dx/dt
dy/dt = 6x^2 dx/dt - 4 dx/dt
substitute dx/dt =4 and x=1
dy/dt = 6 * (1)^2 * 4 - 4(4)
dy/dt = 24-16
dy/dt = 8
Brent estimates that the model's circumference is about 3 times the measure of the circle's diameter, with this, he can estimate the area.
<h3>What is a
circle? </h3>
A circle is the locus of a point, such that the distance from a fixed point (center) is always constant.
The circumference of a circle is given by:
Circumference = π * diameter
