Hello.
The are answer is 4 or 3
<span>
3^2 = 7(3) - 12
9 = 21 - 12
9 = 9
</span>4^2 = 7(4) - 12
16 = 28 - 12
16 = 16
Have a nice day
Answer:
Domain: 
Range: ![[0,4]](https://tex.z-dn.net/?f=%5B0%2C4%5D)
Step-by-step explanation:
<u>Domain</u>
We can see that the piecewise function starts at x=-2, which is included, and ends at x=1, which isn't included. To represent the x-values that lie in between these two endpoints, you would write
. Brackets show that one endpoint is included while parentheses show that one endpoint isn't included.
<u>Range</u>
Following this logic, the range has its y-values go from 0 to 4 with both endpoints included if you were to trace the function. Thus, your range would be
.
Answer: 4 units
Step-by-step explanation:
The given position function:
, where t≥0.
To determine: Total distance traveled by the particle from 0≤ t ≤ 4.0.
At t=0,

At, t=4,

Total distance traveled by the particle from 0≤ t ≤ 4.0 = |42-38| units
= 4 units
Hence, the distance traveled by the particle from 0≤t≤4.0 is 4 units.
Answer:
'

Step-by-step explanation:
Given


Required (Missing part of the question)
(a) The marble is red. (b) The marble is odd-numbered
Solving (a): Probability of Red.
This is calculated as:




Solving (b): Probability of Odd
Since each marble type is numbered 1 to 38, then half of it are odd.
i.e. 19 odd numbered red marbles and 19 odd numbered blue marbles.
So, the probability of odd is:




Answer:
16
Step-by-step explanation:
3 = p/4 - 1
Move the 1 to the other side:
3 + 1 = p/4
4 = p/4
Multiply 4 on both sides to isolate p:
p = 16
