Use the boundedness theorem to determine whether the polynomial function satisfies the given condition. The polynomial f(x) = x4
7nadin3 [17]

Answer:

So f(x) has no real greater than 8. Step - by - step explanation is shown in the attachment.

Step-by-step explanation:

Let f ( x) be a polynomial with real coefficients and with a positive lending coefficient.

If f(x) is divided by x-c and

a) if c>0 and all number in the bottom row of the synthetic division are non negative , then f(x) has no zero greater than c.

b ) if c<0 and the number in the bottom row of the synthetic division alternate in sign  then f (x) has no zero less than c

As shown in the figure

Since the number in the bottom row of the synthetic division alternate in sign

So f(x) has no real greater than 8

Please help ASAP really need this
Aleonysh [2.5K]

Answer:

21.79 + c \leq 25

Joshua can spend up to 3.21 on a card.

Step-by-step explanation:

21.79 + c \leq 25 is the correct equation because Joshua is spending 21.79 on flowers, a certain amount on the card, and the maximum he can spend is 25. That is why you use the less than or equal to sign.

To solve, first subtract 21.79 from both sides to get: c \leq 3.21. This means that Joshua can spend up to 3.21 on a card.

Hope it helps!

Find the volume of the compound shape.​
jeyben [28]
<h3>Given:</h3>
  • Hemisphere ×2 or sphere
  • Cylinder
<h3>Solution:</h3><h3>Volume of the sphere:</h3>

v =  \frac{4}{3}  \pi {r}^{3}

v =  \frac{4}{3}  \times \pi \times  {2}^{3}

v = 33.51 \:  {m}^{3}

<h3>Volume of the cylinder:</h3>

v = \pi {r}^{2} h

v = \pi \times  {2}^{2}  \times 6

v = 75.40 \:  {m}^{3}

<h3>Total volume:</h3>

v = 75.40 + 33.51

v = 108.91 \:  {m}^{3}

<u>Hence</u><u>,</u><u> </u><u>the</u><u> </u><u>volume</u><u> </u><u>of</u><u> </u><u>the</u><u> </u><u>given</u><u> </u><u>compound</u><u> </u><u>shape</u><u> </u><u>is</u><u> </u><u>108.91</u><u> </u><u>cubic</u><u> </u><u>meters</u><u>.</u>
