Answer:

Last option: increasing: -2 < x < 0 and x> 3/2;

decreasing: x < -2 and 0 < x < 3/2

Step-by-step explanation:

The function given is an absolute cubic function. (Pictured below).

We can determine from the graph that the equation increases over the interval:

increasing: -2 < x < 0 and x> 3/2;

decreasing: x < -2 and 0 < x < 3/2

Answer:  d) increasing from -2 to 0 and 3/2 to ∞

                     decreasing from -∞ to -2 and 0 to 3/2

<u>Step-by-step explanation:</u>

Graph the equation.  Then follow the path of the curve from left to right.  If you are going down, then it is decreasing. If you are going up, then it is increasing.

See image below. Blue represents decreasing. Red is increasing.

Note: If you are unable to graph the equation, then find the zeros of the equation, choose test points between the zeros, and plug them into the equation. If the test point is negative, then it is decreasing. If the test point is positive, then it is increasing.

The height (ft) of an object is launched into the air given by the function h(t)=-6t^2+120t+17 where t is the time in seconds.
garri49 [273]

Answer:

Object will reach the max height in 10 seconds.

Max. height is 1817.

It will hit the ground in 20 seconds.

Step-by-step explanation:

In order to find the x value which makes the function take its greatest value, you need to take the derivative of the function and equalize the result to 0.

h'(t)=-12t+120=0

t=10

The object will reach its maximum height in 10 seconds.

h(10) (maximum height) = 6.10.10+120.10+17= 600+1200+17=1817

Considering this is a parabola, time in total is two times more than the time passed until reaching the max. height.

10 points plz help me
lord [1]

Answer:

First drawing - answer is:  D: DG, FG and DE

Second drawing - answer is:  π (pi)

Third drawing - answer is:  70° ( If you mean on measure of central angle which is corresponing to the arc CB)

Fourth drawing - answer is: y=55° ( If you mean that the value of angle ∠AOB=70° )

Step-by-step explanation:

For the second drawing

arc AB = (r · π / 180) · α = (3 · π/180) · 60 = (180 · π) / 180 = π

For the third drawing

∠CAB is peripheral angle of the central angle ∠CFB.

∠CFB= 2·∠CAB= 2· 35° = 70°

Good luck!!!

What is the weight of an object whose mass is 16.4 kg?
MrRissso [65]
The answer is 161.70 N.

EXPLANATION

To change from mass to weight multiply by gravity (9.8 m/s^2) 

Fw = m * 9.8 m/s^2 
Fw = 16.5 kg * 9.8 m/s^2 = 161.70 N.
