4 0

Answer:

f(x)=x^2+8x+24

Step-by-step explanation:

The reason that it is the 4th one is because there is an x^2 which indicates a quadratic and it is negative because the quadratic is going down

If f(x) = |x| + 9 and g(x) = –6, which describes the value of (f + g)(x)? a.)(f + g)(x)≥3 for all values of x b.)(f + g)(x) ≤ 3

mamaluj [8]

Answer:

Answer (a)

Step-by-step explanation:

(f + g)(x) would be equal to |x| + 9 - 6, which reduces to |x| + 3.

Since |x| cannot be less than zero, the range of this composite function

(f + g)(x) = |x| + 3 is [3, infinity). That is, the smallest value is 3. This corresponds to Answer (a).

Answer:

a) 235.62 cm³ (nearest hundredth)

b) 2. tripling the height to 9 cm, while the radius remains 5 cm, gives the most volume

Step-by-step explanation:

volume of a cylinder = $2\pi r^2h$ (where r is the radius and h is the height)

Given:

r = 5 cm
h = 3 cm

a) ⇒ volume = $\pi \times 5^2 \times 3=75\pi =235.62$ cm³ (nearest hundredth)

b) Given:

r = 10 cm
h = 3 cm

⇒ volume = $\pi \times 10^2 \times 3=300\pi =942.48$ cm³ (nearest hundredth)

Given:

r = 5 cm
h = 9 cm

⇒ volume = $\pi \times 5^2 \times 9=225\pi =706.86$ cm³ (nearest hundredth)

Therefore, 2) tripling the height to 9 cm, while the radius remains 5 cm, gives the most volume
