What is a factor of each term of the polynomial?. (3d2 – 10d).

Answers

Answer:

d(3d-10) is the factor term of given polynomial.

Step-by-step explanation:

We have been given an expression:

3d^2-10d

We will take the common term out of the given expression  which is d

Hence, we get:

d(3d-10)

We have been asked the factor term of the polynomial:

Therefore, the factor term of the polynomial is:d(3d-10)



(3d^2 - 10d) = d(3d - 10).

You are 12-15 seconds from an intersection. What should you search for in this range?

Answers

When you are 12-15 seconds away from an intersection while driving, you should search for the following:

1. Traffic lights: Look for traffic lights at the intersection and determine their current state (red, yellow, or green).

2. Hazardous situations: Scan for any potential hazards such as pedestrians, bicycles, or motorcycles approaching or crossing the intersection.

3. Vehicles: Check for any vehicles approaching the intersection, especially those that may turn or change lanes unexpectedly.

4. Road signs and markings: Pay attention to any signs or road markings that may affect your intended path or require you to take specific actions.

5. Road conditions: Observe the road conditions, looking for anything that may affect your ability to safely navigate the intersection, such as wet or icy surfaces.

By actively searching for these elements, you can anticipate potential dangers, make informed decisions, and react in a timely manner to ensure a safe passage through the intersection.

Step-by-step explanation:

An object launched vertically from a point that is 37.5 feet above ground level with an initial velocity of 48.6 feet per second can be represented by the equation h=−16t^2+48.6t+37.5, where h is the height of the object and t is the time after the object is launched. How long does it take the object to hit the ground?

Answers

Answer: 3.675 seconds

Step-by-step explanation:

Hi, when the object hits the ground, h=0:

h=−16t^2+48.6t+37.5

0=−16t^2+48.6t+37.5

We have to apply the quadratic formula:  

For: ax2+ bx + c  

x =[ -b ± √b²-4ac] /2a  

Replacing with the values given:  

a=-16 ; b=48.6; c=37.5

x =[ -(48.6) ± √(-48.6)²-4(-16)37.5] /2(-16)  

x = [ -48.6 ± √ 4,761.96] /-32

x = [ -48.6 ± 69] /-32

Positive:  

x = [ -48.6 + 69] /-32 = -0.6375

Negative:  

x = [ -48.6 - 69] /-32 = 3.675 seconds (seconds can't be negative)

Feel free to ask for more if needed or if you did not understand something.
