In the figure above, circles A and B are tangent to each other and to the large circle. If the radius of circle A

Ne4ueva [31]

Answer:

The answer to your question is A = 200.96 u²

Step-by-step explanation:

Data

Radius A = 6

Radius B = 2

π = 3.14

Area = ?

Formula

Area = πr²

Process

1.- Calculate the radius of the large circle

Radius = radius of circle A + radius of circle B

Radius = 6 + 2

Radius = 8

2.- Substitute in the formula

Area = (3.14)(8)²

Area = 3.14(64)

Area = 200.96 u²

-8(-5+4x)=104 sssssssssssssssssssssssssssssssssssssssss

astra-53 [7]

Answer:

what is the meaning of 'sssssssssssssssssssssssss'

the answer is x=2

first work out -8(-5+4x) u will get 40+32x

40+32x=104 then group the like terms together.

it will become 32x=104-40. =32x=64

then divide both sides by 32 ur final answer is

x =2

d1i1m1o1n [39]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Average number of arrivals = 6 per hour

Service rate = 3 every 15 minutes

Service rate is given by

$\mu=\dfrac{60\times 3}{15}=12$

So, the average number of customers in the system is given by

$\dfrac{\mu}{\mu-\lambda}\\\\=\dfrac{6}{12-6}\\\\=\dfrac{6}{6}\\\\=1$

Hence, Option 'c' is correct.

Please do the agree or disagree part and justification

Jlenok [28]

Answer:

<em>We disagree with Zach and Delia and agree with Alicia</em>

Step-by-step explanation:

The domain of a function is the set of values of the independent variable that the function can take according to given rules or restrictions.

The range is the set of values the dependent variable can take for every possible value of the domain.

The graph shows a continuous line representing the values of the function. We must take a careful look to the values of x (horizontal axis) where the function exists. It can be done by drawing an imaginary vertical line passing through the value of x. If that line touches the graph of the function, it belongs to the domain. It's clear that every value of x between -5 and 3 (both inclusive because there are solid dots in the extremes) belong to the domain:

Domain: $-5\leq x \leq 3$

The range is obtained in a similar way as the domain, but the imaginary lines must be horizontal. That gives us the values of y range from -7 to 5 both inclusive:

Range:

$-7\leq y \leq 5$

Thus we disagree with Zach and Delia and agree with Alicia
