Answer:
C.
Step-by-step explanation:
Even if it is a piecewise function, we don't really need to approach it that way. Since both of the given equations have a slope, our only viable option is C because it is the only graph that shows the 2 slopes. All the other graphs show 1 slope and a 0 slope (horizontal line) so C. is our best choice.
Statement: ALL square roots are irrational numbers.
Irrational is defined as a non-terminating real number.
✓4 = 2
2 is a terminating real number.
Therefore, 2 is rational.
The square root of 4 results in 2.
Therefore the square root of 4 results in a rational number.
Hence not all square roots result in irrational numbers.

Answer:
$8.65×10^3
Step-by-step explanation:
The amount the West raised is the difference between the total and the sum of the other amounts raised. It is convenient to use a multiplier of 10^4 for each of the numbers, so the number for South can be rewritten as 0.675×10^4.
West = 5.38×10^4 -1.46×10^4 -2.38×10^4 -0.675×10^4
= (5.38 -1.46 -2.38 -0.675)×10^4
= 0.865×10^4 = 8.65×10^3
West raised $8.65×10^3.

Answer: Jessica is correct
==================================================
Explanation:
- Antonio is not correct because 3 cubed is not 9. Instead, it's 3^3 = 27. Note that 3^3 = 3*3*3 = 27. Another example would be 4^3 = 4*4*4 = 64. The good news is that he has the correct starting expression because the r^3+9 portion is the sum of r cubed and 9, then we double it.
- Jessica is correct. She has the correct starting expression and has evaluated 3^3 correctly. Also, the final answer 72 is correct as well.
- Maria doesn't have the correct starting expression.
- The same goes for Mark. His starting expression isn't correct.
What is the relationship between v(t), x(t), and a(t)? I assume that v(t) is a velocity and x(t) is distance traveled in relation to v(t) and a(t) is the acceleration in relation to v(t). So . . .
x(t) =
∫v(t)dt
= ∫(8t + 25)dt = 4
+ C
a(t) = d/dt(v(t)) = d/dt(8t+25) = 8
