What does it mean to square a negative number

Andrej [43]

Answer:

This is because to square a number just means to multiply it by itself. For example, (-2) squared is (-2)(-2) = 4. Note that this is positive because when you multiply two negative numbers you get a positive result.

A cylinder has a volume of 540 cm cubed. if the height of the cylidner is 15 cm, find the radius.

Tamiku [17]

You should always remember that a cylinder consists of circles that are all over each other to form the height of the cylinder.
So the volume of the cylinder= the area of the surface circle* the height.
$V=540=\pi r^2*h= \pi r^2*15$
Then,
$r^2= \frac{540}{15 \pi }$
So, $r= \sqrt{\frac{540}{15 \pi }}$
radius is approximately 3.4cm

3. A car starts from rest and accelerates uniformly over a time of 6.21 seconds

Klio2033 [76]

We have,

t = 6.21 s

s = 111 m

u = 0 m/s

To determine: "a" of the particle.

We know,

s = ut + ½ at²

⇒ s = ½ at²

⇒ a = 2s/t²

⇒ a = [2(111 m)]/(6.21 s)²

⇒ a = (222 m)/(38.5641 s²)

⇒ a ≈ 5.75 m/s²

1250 randomly chosen individuals from a certain population are tested for the presence of the HIV virus, and 20 are found to be

Harrizon [31]

Answer:

0.016

Step-by-step explanation:

To find the probability we have to Divide the number of events by the total number of possible outcomes. This will result in the probability of the single event.

Therefore, the formula of probability is

$P(v) = \frac{no of events}{total possible outcomes}\\$

In the given case,

$P(v) = \frac{20}{1250}\\ P(v) = 0.016$

Which is our required answer.
