Answer: x-intercept
<u>Step-by-step explanation:</u>
NOTES
1) Parabolic motion is represented by the equation:
h(t) = -9.8t² + vt + h (in meters per second²), v is velocity
or
h(t) = -32t² + vt + h (in feet per second²), v is velocity
2) The x-axis is time (in seconds) & the y-axis is height (in meters or feet).
Since you want to know what time the object hit the ground, h = 0
Therefore, you are looking for the zero of the equation, which is on the x-axis, thus is the x-intercept.
The answer is 25n because force= mass times acceleration
Answer:
B
Step-by-step explanation:
To find the y-intercept, plug in x=0 in the original equation. (You want to find what y is when x=0)
2x + 3y = -12
2(0) + 3y = -12 (Plug in x=0)
3y = -12 (2*0=0, so you can ignore that part)
y = -4 (Divide both sides by 3)
This narrows down our choices to either A or B.
To find the x-intercept, plug in y=0 into the original equation. (You want to find what x is when y=0)
2x + 3y = -12
2x + 3(0) = -12 (Plug in y=0)
2x = -12 (3*0=0, so you can ignore that part)
x = -6 (Divide both sides by 2)
If our x intercept is -6 and our y intercept is -4, that makes our answer B.
Answer:
3
Step-by-step explanation:
Add up the exponents of the variables
5xyz = 1+1+1 = 3
The degree is 3
Answer:
C
Step-by-step explanation:
- The domain is all the x numbers for each point
- So -5,-4,0,2,4
