Answer:

Perimeter: 61.41 units

Area: 136.68 units squared

Step-by-step explanation:

Circle Formulas

Circumference = 2πr

Area = πr^2

Perimeter

add all sides and 1/4 of the circumference of that circle

10 + 10 + 5 + 5 + 2π5

10 + 10 + 5 + 5 + 31.41

61.41

Area

How much space that shape takes up

10 x 10 x 3/4 = 75

π5^2 = 246.74

246.74 x 1/4 = 61.68

61.68 + 75 = 136.68

Cassandra is creating an animated short film, and she needs 35 frames per second of film. He already has at least 200 frames.

scZoUnD [109]

Answer: C) f ≥ 35s - 200

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

She needs 35 frames (f) per second (s) ( we have to multiply the number of frames by the number of seconds) f ≥ 35s

She has already 200 frames (since we already have, we can subtract that to the needed frames per second)

f ≥35s -200

Feel free to ask for more if needed or if you did not understand something.

The exponential equation of the model is A(t) = 2583 * 0.88^t and the multiplier means that the number of new cases in a week is 88% of the previous week

<h3>The function that models the data</h3>

The given parameters are:

New, A(t) = 2000

Rate, r = 12%

The function is represented as:

A(t) = A * (1 - r)^t

So, we have:

2000 = A * (1 - 12%)^t

This gives

2000 = A * (0.88)^t

2 weeks ago implies that;

t = 2

So, we have:

2000 = A * 0.88^2

Evaluate

2000 = A * 0.7744

Divide by 0.7744

A = 2583

Substitute A = 2583 in A(t) = A * 0.88^t

A(t) = 2583 * 0.88^t

Hence, the exponential equation of the model is A(t) = 2583 * 0.88^t

<h3>The interpretation of the multiplier</h3>

In this case, the multiplier is 88% or 0.88

This means that the number of new cases in a week is 88% of the previous week

In order to join a flying club,there is a $200 annual fee and $20 a month fee to maintain the flying club runaway.Write an equat

Fudgin [204]

Answer:

The equation modelling the situation is $T=200+20m$ .

After <u>10 months</u> the cost would be $400.

Step-by-step explanation:

Given:

Annual Fee of flying club = $200

Monthly fee = $20

We need to write an equation for total cost.

Solution:

Let the number of months be denoted 'm'

Let Total cost be denoted by 'T'

Now we can say that:

Total cost is equal to sum of Annual Fee of flying club plus Monthly fee multiplied by number of months.

framing in equation form we get;

$T=200+20m$

Hence The equation modelling the situation is $T=200+20m$ .

Now given:

We need to find the number of months when total cost will be $400

So we will substitute T= 400 in above equation.

$200+20m=400$

Subtracting both side by 200 we get;

$200+20m-200=400-200\\\\20m=200$

Dividing both side by 20 we get;

$\frac{20m}{20}=\frac{200}{20}\\\\m=10 \ months$

Hence After <u>10 months</u> the cost would be $400.
