Question

1.
The height of a ball when it is thrown into the air is shown by equation h = −16t2 + 20t + 3, where h is the height of the ball and t is time in seconds since the ball was released.
2.
A salesperson’s monthly earnings are shown by the equation e = 1200 + 0.04s, where e represents the salesperson’s monthly earnings and s is her monthly sales.3.
The amount of a 500 g sample of a radioactive substance that remains over time is given by the equation , where d is the number of days since the sample weight was 500 g.

Answer 3

Is each situation a linear or a nonlinear model?

Answer 4

h = −16t² + 20t + 3
is a quadratic (so non-linear) equation

Answer 5

k do you know the others? and #3 doesnt have anything so dont worry about it

Answer 6

2.
e = 1200 + 0.04s
is a linear equation

x² refers to quadratic
s -> linear

Answer 7

do you know #4?

Answer 8

i think its linear!!!:D

Answer 9

Mikaela’s distance from home as she drives at a constant rate is b

again, unless it is somewhere explained how to derive the equation, this question os badly posed, but
d = distance
speed = b is constant
t = time

d = b*t

is linear

Answer 10

eq 3 should be
\[M = 500 e^{⁻\lambda d}\]

Answer 11

it is non-linear
