Let the function be f defined by f (x) = 12 - 5x

Mathematics
1 answer:
marissa [1.9K]3 years ago
7 0

(a) No

f(x) = 12 - 5x

f(0) = 12 - 5(0)

f(x) = 12 - 0

f(x) = 12

Hence,

f(0) is unequal to 0.

(b)

f(x) = 12 - 5x

f( - 1) = 12 - 5( - 1)

f( - 1) = 12 + 5

f( - 1) = 17

(c)

f(x) = 12 - 5x

f(x) = 6

6 = 12 - 5x

6 - 12 =  - 5x

- 6 =  - 5x

6 = 5x

\frac{6}{5}  = x

The water level in a tank can be modeled by the function h(t)=8cos(pi t /7)+11.5, where t is the number of
denis23 [38]

Answer:

NO amount of hour passed between two consecutive times when the water in the tank is at its maximum height

Step-by-step explanation:

Given the water tank level modelled by the function h(t)=8cos(pi t /7)+11.5. At maximum height, the velocity of the water tank is zero

Velocity is the change in distance with respect to time.

V = {d(h(t)}/dt = -8π/7sin(πt/7)

At maximum height, -8π/7sin(πt/7) = 0

-Sin(πt/7) = 0

sin(πt/7) = 0

Taking the arcsin of both sides

arcsin(sin(πt/7)) = arcsin0

πt/7 = 0

t = 0

This shows that NO hour passed between two consecutive times when the water in the tank is at its maximum height
