Gnoma [55]

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

Write a quadratic function with zeros -1 and 5.

Shalnov [3]

Answer:

$x^2+4x-5$

Step-by-step explanation:

Zeros of a quadratic equation are -1 and 5.

Sum of zeros = -1 + 5 = 4

Product of zeros = (-1)(5) = -5

The quadratic equation will be :

$x^2+(\text{sum of zeros})x+\text{product of zeros}\\\\=x^2+4x-5$

So, the required quadratic equation is $x^2+4x-5$ .
