Answer:

Option D is correct.

$\overline{BC} = 122$ units

Step-by-step explanation:

Using Pythagoras theorem:

$\text{Hypotenuse side}^2 = \text{Opposite side}^2+ \text{Adjacent side}^2$

As per the given right angle triangle ABC diagram:

In triangle ABC; we have

Hypotenuse side = BC

Opposite side = AB = 22 units

Adjacent side =AC= 120 units

Apply the Pythagoras theorem on rt angle triangle ABC we have;

$\text{BC}^2 = 22^2+120^2$

⇒ $\text{BC}^2 = 484+14400 = 14884$

⇒ $\tet{BC} = \sqrt{14884}=122$ units

Therefore, the length of side BC is, 122 units

AB²+AC²=BC²
120²+22²=BC²
14884=BC²
BC=122

Find the radius of the circle whose equation is x^2 + y^2 = 4.

KATRIN_1 [288]

Answer:

Radius of the given circle is r = 2.

Step-by-step explanation:

Given equation of the circle is $x^2 + y^2 = 4$ .

Now we need to find the radius of the given circle $x^2 + y^2 = 4$ .

To find that let's compare with the formula of the circle with is $x^2 + y^2 = r^2$ , where r is the radius.

We get $r^2 = 4$

take square root of both sides.

$r=2$

Hence radius of the given circle is r = 2.

1. The equation y=x^2-9x+20 models the roller coasters path over time. The variable y represents height (in feet) above or below

azamat

Answer:

1) the factored form is y= ( x-5 ) ( x+4 )

2) the vertex is (4.5, -0.25)

3) the y intercept is when x equals 0 so it is at (0,20)

4) it opens upward and the vertex is (4.5, -0.25) the x intercepts are (4,0) and (5,0) and the y intercept is (0,20)

a. it dips between 4 seconds and 5 seconds so the x intercepts are (4,0) and (5,0)

b. it is taken at the vertex aka the lowest point so the height is -0.25

Ignoring leap days, the days of the year can be numbered 1 to 365. Assume that birthdays are equally likely to fall on any day o

faust18 [17]

Answer:

Follows are the solution to the given question:

Step-by-step explanation:

They can count the days of the year 1 to 365. The random project consists of drawing a sample of n objects from D where elements are n people's birth in a group but instead, D = {1,....365}. And then there's the issue.

$S=365^n$

This because the list of future birthdays of n people was its test point; therefore m points will be in the sequence so each point contains 365 distinct outcomes. The probability function P for \Omega is that any event is likely to happen in 365 days.

$P(x)=\frac{1}{365^{n}}$

if x is between 1 and 365 as well as the occurrence is just all similarly possible

In point i:

That somebody mentions their birthday throughout the party

Guess I was born on day b. Therefore the consequence of "x is in A" is "b is now in the series of x," which is to say, b = bk for some amount k approximately 1 and n.

In point ii:

Any 2 persons share the same birthday at this party". A result x is in B" means which "two of entries in x are same." This means that perhaps the outcome x is in B if or only if bj = bk is in B of two numbers j, and k of 1, of two. , no, n.

In point iii:

Many three students share the same birthday with both the party. The consequence is x at the level of C only when bj = bk = bl at three (different) indices, j, k, l, 1. , no, n.
