Answer:

50π cm²

Step-by-step explanation:

In this case we have that the area of the boomerang has been the area of the largest semicircle minus the area of the smaller semicircles.

We know that the radius is half the diameter:

r = d / 2 = 20/2

r = 10

Now we have to:

Alargest = π · r²

Alargest = π · (10 cm) ²

Alargest = 100π cm²

Asmaller = π · r²

Asmaller = π · (5 cm) ²

Asmaller = 25π cm²

Finally, the boomerang area has been:

Aboomerang = 100π cm² - 2 · (25π cm²)

Aboomerang = 50π cm²

The club's total number of members will grow exponentially each month. She uses the given expression to model the number of club

mihalych1998 [28]

Answer:

1.8 represents the initial number of the club members in hundreds.

Step-by-step explanation:

* Lets revise the exponential grows

- If a quantity grows by a fixed percent at regular intervals,

the pattern can be depicted by this function.

- The function of the exponential growth is:

y = a(1 + r)^x

# a = initial value (the amount before measuring growth)

# r = growth rate (most often represented as a percentage and

expressed as a decimal)

# x = number of time intervals that have passed

* Now Lets study the problem to solve it

- The club's total number of members will grow exponentially

each month

- The expression to model the number of club members, in

hundreds, after advertising for t months is

1.8(1.02)^12t

* Lets compare between this model and the function above

# a = 1.8 ⇒ initial number of members in hundreds

# r = 1.02 - 1 = 0.02 ⇒ growth rate

# x = 12t ⇒ number of time intervals

* 1.8 represents the initial number of the club members in hundreds.

Help fast!! What is the exact volume of the cylinder? 36 324 54 18 in

xxMikexx [17]

Answer:

V = 54 pi in ^3

Step-by-step explanation:

The volume of a cylinder is given by

V = pi r^2 h where r is the radius and h is the height

V = pi (3)^2 * 6

V = pi (9) *6

V = 54 pi in ^3

If 3t=5t-8 evaluate -4t+5

Sergio [31]

3t = 5t - 8

-2t = -8

t = 4

Now put that into -4t + 5:

-4t + 5

-4(4) + 5

-16 + 5

-11

2 1 point The point, (-3, 7), is on the line y = -3x+7. True O False

sladkih [1.3K]

Step-by-step explanation:

in order to know if the the point is on the line plug in the x coordinate to check if it gives you the y coordinate as an output.
If you plug in the x coordinate and it gives you the given y coordinate then the point is on the given line
Now let us plug in the value of x=-3
$y = - 3( - 3) + 7 \\ y = - 9 + 7 \\ y = - 2$
now if you check plugging in the given x coordinate it does not give you the given y coordinate but -2
therefore the point(-3,7) is not in the line but (-3,-2) is the point in the line.
