Answer:

60.6

Step-by-step explanation:

The rectangle is 12*4. You have the radius of the semicircle, so you multiply that by 2 to get 4 for the diameter, then getting the width of the rectangle.

After that, do pi * r^2. This will be pi*4. You'll get 12.6.

After multiplying 12*4, 48, you add 12.6 and 48, and get 60.6

write and solve a real world problem in which you need to find the initial value of the function. Then explain how you solved th
Mama L [17]

you are planting roses

you started at 12 noon

at 3pm, you have 80 roses left

at 6pm, you have 20 roses left

if you planted roses at a constant rate, how many roses did you start with?

so we can find the slope of this linear function as (20roses-80roses)/(6pm-3pm)=60roses/3hrs=-20roses/hr

your quantity goes down by 20 roses per hour (you plant 20 per hour)

r=-20t+?

find ?, the number of roses when t=0

at 3pm yo have 80 roses

80=-20(3)+?

80=-60+?

140=?

you had 140 roses intiailly




if you wanted an exponenntial

the town polpulationn grows at an exponential rate

the town was founded in 2000

in 2010, the town's population was 1000

in 2015, the town's populationw as 2000

find intial polpulation


exponential can be modeled by y=ab^t where y=population, t=time and b and a are constants (a=initial population)

we are given that after 10 years (2010), y=102400

after 15 years, (2015), y=3276800

so

102400=ab^{10} and 3276800=ab^{15}

divide the 2nd by the first equation, remembering our exponential properties like \frac{x^a}{x^b}=x^{a-b}

32=b^{5}

take 5th root of both sides

b=2

subsitute back

102400=ab^{10}

102400=a(2)^{10}

102400=1024a

100=a

the intial population is 100 people

Step-by-step explanation:

A perfect number is one whose divisors total the number itself. Only 51 perfect numbers are known at this time. The first five are ...

  6, 28, 496, 8128, 33550336

The fourth perfect number is 8128. Its divisors (excluding the number itself) are ...

Which is true about the completely simplified difference of the polynomials a3b 9a2b2 − 4ab5 and a3b − 3a2b2 ab5?.
PtichkaEL [24]

The simplified difference of the polynomials (a³b+9a²b²-4ab⁵) and (a³b-3a²b²+ab⁵) is (12a²b²-5ab⁵).

<h3>What are Like terms?</h3>

Like terms are those terms that are having the same variables, also the variables are of the same order as well.

for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.

Let's simplify the two of the given polynomials, therefore, find the difference between the two given polynomials.

a^3b+9a^2b^2 - 4ab^5 - (a^3b - 3a^2b^2+ab^5)\\\\= a^3b+9a^2b^2 - 4ab^5 - a^3b + 3a^2b^2-ab^5\\\\\text{Bring Like terms together}\\\\=a^3b - a^3b+9a^2b^2+3a^2b^2 -4ab^5-ab^5\\\\= 12a^2b^2-5ab^5

Hence, the simplified difference of the polynomials (a³b+9a²b²-4ab⁵) and (a³b-3a²b²+ab⁵) is (12a²b²-5ab⁵).
