Answer:

4x-3y=-6

Step-by-step explanation:

If the population doubles every 42 years then the population will be after 168 years from now, 7,498,000

An exponential function is a mathematical function which we write as a

f(x) = aˣ, where a is constant and x is variable term. The most commonly used exponential function is eˣ , where e is constant having value 2.7182

We can use exponential growth:

If the population doubles every 42 years, the population after t years can be modeled as:

P = 467,500 x 2^(t/42)

where P is the population after t years and 467,500 is the current population.

To find the population 168 years from now, we can plug in t = 168:

P = 467,500 x 2^(168/42)

  = 467,500 x 2⁴

  = 467,500 x 16

  = 7,498,000

So, the population of the city 168 years from now is approximately 7,498,000.

Answer:

x = 4

Step-by-step explanation:

In this equation, x is being cubed to equal 64. When x is being cubed, it means that x is multiplied by itself 3 times to get 64. Thus, we have to find which number to the power of three = 64.

Therefore, x = 4.

Equation: 3√64 = x

In case you needed it

This so happens to be a perfect cube

Cube = A number raised to the power of 3

1 x 1 x 1 = 1

2 x 2 x 2 = 8

3 x 3 x 3 = 27

4 x 4 x 4 = 64

So therefore, x = 4

Step-by-step explanation:

Givens

arc length DF = 30

pi = 3.14

Comment

The problem is that it looks to me like you have marked DF = 30. That's not what is given. What you are given is a part of the circumference is equal to 30.

Solution

The formula you should be using 100/360 * 2 * pi * r You should be solving for r.

30 = 100/360 * 2 * pi * r                 Multiply both sides by 360

30*360 = 100 * 2 * pi * r                Combine left and right

10800 = 200* 3.14 * r

10800 = 628 * r                              Switch Divide both sides by 628

628 * r/ 628 = 10800 / 628

r = 17.197

Answer

Area of the circle = pi*r^2

Area of the circle = 3.14 * 17.197^2

Area of the circle = 928.66 m^2

Answer:

The missing length would be 6

Step-by-step explanation:

Answer:

9

Step-by-step explanation:

Follow the order of operations:

Given expression:  6 ÷ 2(1 + 2)

Carry out the operation inside the parentheses first:

⇒ 6 ÷ 2(3)

⇒ 6 ÷ 2 × 3

Now multiply/divide by going left to right:

⇒ 3 × 3 = 9

Solution:

To solve this problem, we will need to use the "BODMAS".

Solving the expression:

[tex]\bullet \ \ 6 \div 2(1 + 2)[/tex]

First, simplify the expression inside the brackets.

[tex]\bullet \rightarrow 6 \div 2(3) \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ [\ex\text{Bracket addition}][/tex]

Now, 2(3) can also be written as 2 × 3, as 2(3) and 2 × 3 are equivalent.

[tex]\bullet \rightarrow 6 \div 2 \times 3[/tex]

According to the BODMAS, division first.

[tex]\bullet \rightarrow 3 \times 3 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ [\ex\text{Division}][/tex]

According to the BODMAS, multiplication next.

[tex]\bullet \rightarrow \boxed{\bold{9}} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ [\tex\text{Multiplication}][/tex]

Thus, the solution to 6 ÷ 2(1 + 2) is 9.

Answer: X=1 Y=-5

Step-by-step explanation:

−9x+2y+−2y=−19+−2y(Add -2y to both sides)

−9x=−2y−19 (Divide by 9 on both sides)

x= 2/9y+19/9 now Substitute 5(2/9y+19/9)+4y=-15=

46/9+95/9=-15 (simplify both sides)

46/9+95/9+-95/9=-15+-95/9 (Add (-95)/9 to both sides) =

46/9y=-230/9 (now divide both sides by 46/9) than equals

y=-5

for X we plug in -5 like this: X=2/9(-5)+19/9 now just evaluate than simplify both sides which equals: 1

Answer:

The reflection of a horizontal line has the same result as a rotation of 90 degrees clockwise.

Answer: Choice B

270 degree rotation clockwise

=======================================================

Explanation:

Notice that 270+90 = 360

Going 90 degrees in one direction is the same as going 270 degrees in the other direction because the two combine to a full 360 degree rotation.

Check out the image below for an example. In the example, the point P starts at (0,5). Doing either rotation mentioned will get us to (-5,0).

Answer: Evie will be 6 years old in one year.

2 years ago, Evie was 3 years old. Now, she is 5. 4 years after 5 would make her 9. 3*3=9

If  In four years time Evie will be three times older than she was two years ago, then in one year's time Evie will be 6

Two or more expressions with an Equal sign is called as Equation.

Given,

In four years time Evie will be three times older than she was two years ago,

Let the age of Evie be x in one year.

By the given information we formulate a equation.

In four years time means we have to add 4 to the present age, x+4.

three times older than she was two years ago can be written as 3(x-2)

Now,

In four years time Evie will be three times older than she was two years ago

x + 4 = 3(x − 2)

Apply distributive property on RHS side

x+4=3x-6

x-3x=-6-4

-2x=-10

x=5

Therefore in one year's time Evie will be x+1 =6, 6 years old.

3 × 10 = 30

sense 3 is what is being talked about, 3 in the 300 is 100 times and 3 in 30 is 10 times.

100 is 10 times 10

10 × 10 = 100
