Answer:

<em>Length of x ~ 10.5; Option B</em>

Step-by-step explanation:

1. There are three radii present in this problem. Of that the diamter is supposedly 42.2 units. Given that the radii should be ⇒ 42.2 / 2 ⇒ 21.2 units

2. With that being said the 3rd radii contains parts x and 10.6. By radii congruency, the length of all radii should be the same, so this 3rd radii should = 21.2 units as well. If so, by the Partition Postulate 21.2 = x + 10.6

3. Through algebra let us solve for x:

21.2 = x + 10.6,

x = 21.2 - 10.6,

<em>Answer ~ Length of x: 10.5</em>

Honestly I dont know how to do this just please help me

F(x) = 3x - 2
f(8) = 3(8) - 2
f(8) = 24 - 2
f(8) = 22
f(-5) = 3(-5) - 2
f(-5) = -15 - 2
f(-5) = -17
f(8) - f(-5) = 22 - (-17)
f(8) - f(-5) = 39
Hope this helped! Good luck! :)

Points A, B, and C are collinear. Point B is between A and C. Solve for x if AC = 3x + 3, BC = 3, and AB = 2x + 2.

Ksenya-84 [330]

Answer:

x=2.

Step-by-step explanation:

It is given that points A, B, and C are collinear. Point B is between A and C.

Using segment addition property, we get

$AC=AB+BC$

It is given that AC = 3x + 3, BC = 3, and AB = 2x + 2.

$3x+3=(2x+2)+3$

$3x+3=2x+5$

Isolate variable terms.

$3x-2x=5-3$

$x=2$

Therefore, the value of x is 2.

Noah loves the Half-Tens facts and often uses them to solve multiplication problems. Make up a 2-digit by 3-digit multiplication

Stells [14]

Half Tens is a way of multiplying where we have to find the value of given numbers. First we double any 'one' of the two given numbers and multiply both to get an answer. Then we divide that answer by '2' to get the answer.

Lets take two numbers as 16 and 340

$16\times340=?$

Double the number 16

$32\times340=10880$

Now we will divide this by 2

$\frac{10880}{2}= 5440$

So, if we check $16\times340=?$ , it is 5440.

Similarly if we double the number 340, we get 680

Now, $16\times680=10880$

And 10880/2 = 5440

Hence, in both ways the answer is 5440.

The number of visitors to an art museum increases each year. The function V(t) = N(1 + r)t represents the number of visitors to

IrinaVladis [17]

Answer:

Option A - The number of visitors is multiplied by (1+r) each year

Step-by-step explanation:

Given : The number of visitors to an art museum increases each year. The function $V(t) = N(1 + r)^t$ represents the number of visitors to the museum at year t, where N is the number of visitors in year 0 and r is the rate of increase.

To find : Select the correct statement?

Solution :

We have given an exponential function,

The function $V(t) = N(1 + r)^t$ represents the number of visitors to the museum at year t, where N is the number of visitors in year 0 and r is the rate of increase.

As In year 0,

The initial visitors is $V(t) = N(1 + r)^0=N$
