Answer:
[-4,5]
Step-by-step explanation:
you look on the starting point and the ending point of the y-axis ( you always start with the smallest value)
Data: (Cylinder)
h (height) = 8 cm
r (radius) = 5 cm
Adopting:

V (volume) = ?
Solving:(<span>Cylinder volume)
</span>




<span>Note: Now, let's find the volume of a hemisphere.
</span>
Data: (hemisphere volume)
V (volume) = ?
r (radius) = 5 cm
Adopting:

If: We know that the volume of a sphere is

, but we have a hemisphere, so the formula will be half the volume of the hemisphere

Formula: (<span>Volume of the hemisphere)
</span>

Solving:





<span>Now, to find the total volume of the figure, add the values: (cylinder volume + hemisphere volume)
</span>
Volume of the figure = cylinder volume + hemisphere volume
Volume of the figure = 628 cm³ + 261.6 cm³
Answer:
Let's simplify step-by-step.
0.8x+19−0.7x
=0.8x+19+−0.7x
Combine Like Terms:
=0.8x+19+−0.7x
=(0.8x+−0.7x)+(19)
=0.1x+19
Answer:
=0.1x+19

Answer:
- 2 complex roots
- 2 positive real roots
- 0 negative real roots
Step-by-step explanation:
The signs of the terms are + - - +. There are two sign changes, so 0 or 2 positive real roots.
Negating the signs of the odd-degree terms, the signs are + + + +. There are no sign changes, so 0 negative real roots.
For x=0, the value of the quartic is +3. For x=1, the value is -3, so we know there are 2 positive real roots, one of which lies in the interval (0, 1).
The 4th-degree polynomial equation must have 4 roots, so the other two must be complex.
- 2 complex roots
- 2 positive real roots
- 0 negative real roots
