The population of a rural town is 250 people. It is expected that the population of the town will double every decade. Which function represents p(d), the population
after d decades?

a. p(d) = 2^d + 250
b. p(d) = 2(250)^d
c. p(d) = 250(2)^d
d. p(d) = 2d + 250

Answer:

12

Step-by-step explanation:

18*2=36, 60-36=24, 24/2=12

The width of the room if the length is 18m is 1.66m.

We have given that,

Perimeter=60 and length=18m

P=2(l+w)

Where the l is the length and

W is the width

Perimeter=60 and length=18m.

Use this value in the formula of perimeter

60=2(18×W)

Divide both sides by 2

30=18w

isolate the w

Therefore, divide both sides by 18.

30/18=w

W=1.66m

Therefore the width of the room if the length is 18m is 1.66m.

No, Tony is not correct. Solving the inequality tells us that x is greater than or equal to 37.5 . Since the class must wash a whole number of cars, they need to wash at least 38 cars.

Step-by-step explanation:

This is the sample response

(I just took the assignment lol)

Answer:

The solution to the inequality is x Greater-than-or-equal-to 37.5.

For this situation, only whole number solutions make sense.

Tony needs to round up to 38.

Step-by-step explanation:

Step-by-step explanation:

Use the formula for compound interest

f/p: f =p(1+i)^n

p = 3300

i =8% = 0.08

n = 9 years

A = p(1+r)^t

A = 3300(1+0.08)⁹

A = 3300× 1.99

A= 6596.71 dollar ~ 6597 dollar.

Answer:

80 meters

Step-by-step explanation:

Length of rectangular field = x

Width of rectangular field = 50

Meters of Fencing required = perimeter of rectangle = 260 m

Perimeter of a rectangle = 2(length + width)

260 = 2(x + 50)

260 = 2x + 100

260 - 100 = 2x

160 = 2x

x = 160 / 2

x = 80 meters

The total length

To get the total length (actual length), multiply the scale ratio by the scale distance;

Answer:

The center of the circle is at the coordinate: (1,6)

Explaination:

To find the answer all you need to do is add the x values together and divide by two and add the y values together and divide by two:

[tex]\frac{5-3}{2} =1[/tex] (x-values)

[tex]\frac{5+7}{2} =6[/tex]  (y-values)

Therfore the center is at point (1,6)

Answer:

(1, 6 )

Step-by-step explanation:

The centre of the circle is at the midpoint of the diameter

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )

Here (x₁, y₁ ) = (- 3, 5) and (x₂, y₂ ) = (5, 7) , then

midpoint = ( [tex]\frac{-3+5}{2}[/tex], [tex]\frac{5+7}{2}[/tex] ) = ([tex]\frac{2}{2}[/tex], [tex]\frac{12}{2}[/tex] ) = (1, 6 )

The centre of the circle is (1, 6 )

Ans: Function is a special type of relation. Function is the refinement of relation.

In other words , if no two different ordered pairs have the same first component , then it is a function.

Answer:

third side is 2√33

Step-by-step explanation:

Hi there!

We need to find the third side (hypotenuse, or the side opposite to the right angle) of the triangle, and we're given the measures of the 2 other sides (legs, or the sides make up the right angle)

To find the hypotenuse, we can use Pythagorean theorem, which is given as:

a²+b²=c², where a and b are the legs, and c is the hypotenuse

as stated above, we know that the legs are 7 and √83

substitute them as a and b into the theorem

remember that (√x)²=(√x)(√x)=x

7²+(√83)²=c²

raise all numbers (multiply 7 by itself and multiply √83 by itself)

49+83=c²

add 49 and 83 together

132=c²

take the square root of both sides

√132=c

the question asks for simplest radical form, written as x√y, where x is the square root of a perfect square, and y is what's left after the prefect square is pulled out. For example, 2√3 is √12 (12 is 4*3, and 4 is a perfect square. Recall that √xy is equal to √x*√y. Taking the square root of 4 gives us 2, while taking the square root 3 gives us √3. Multiplying them together makes the number 2√3)

132 is divisible by 4 (the last two digits makes 32, which is divisible by 4). 132/4=33

so 132 is 4*33

pull out 4 from under the radical, take the square root of it, and leave √33 as is

the simplified radical form is 2√33

So the third side is 2√33

Hope this helps!

Answer: A) Linear

Step-by-step explanation: When we look at the table, we see that when x increases from -3 to 4 (change of +7), y increases from -3 to 1 (change of +4). When we increase x by 7 again to 11, we see that y again increases by 4. Since the function is increasing a constant rate (which is 4/7), we know that the function is linear.
