Answer: 6 × 4^x

Step-by-step explanation:

From the question, we are told that scientists released 6 rabbits into a new habitat in year 0 and that each year, there were four times as many rabbits as the year before.

The number of rabbits there after x years will be:

= 6 × 4^x

For example, let us say we want to calculate the number of rabbits after 2 years.

= 6 × 4^x

= 6 × 4²

= 6 × 16

= 96 rabbits

I would say Acute. The angle is definitely less than a right angle. Reflex angles are angles more than 180 degrees, but less than 360 degrees.

Answer:

12 hat/scarf outfits

Step-by-step explanation:

If a snowman has 3 old felt hats and 4 scarves from which to choose, how many different hat/scarf outfits can he wear?

We solve this question using the fundamental counting principle.

This states that:

When we have two events, a and bthe number of ways both events can happen is a × b

From the above question, our two events is

a = 3 old felt hats

b = 4 scarves

Hence, the different hat/scarf outfits can he wear is given as

3 × 4 = 12 hat/scarf outfits

Answer:

- 2 feets

Step-by-step explanation:

Given that sea star can be found at an ocean depth of 2 feets ;

An ocean depth of 2 feets can be represented as :

Sea level - depth = 0 - 2 = - 2 feets

Hence, it can be concluded that sea star lives in the ocean

Answer: Rhombus

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

Explanation:

The tickmarks show that all four sides are the same length. Therefore, this figure is a rhombus. It is not a square because the angle would need to be 90 degrees. We can say it is a non-square rhombus, or a rhombus that isn't a square. It is also not a rectangle either because all rectangles have each angle at 90 degrees.

Answer:

18

Step-by-step explanation:

area of the square-->12

area of the triangle--->6

area of the square + area of the triangle = area of the trapezoid

12+6=area of the trapezoid

18 = area of the trapezoid

_____

The graph shows the solutions to f(x) = 0, where f(x) = √(4x²) -√(x²) -6.

Step-by-step explanation:

d=(3/4)-(1/4)=(5/4)-(3/4)=(7/4)-(5/4)=1/2

then it is an arithmetic sequence

by using this equation :

a(n) = a1 +(n-1)d

and we have : a1=(1/4),  d=(1/2)

So:

Explicit formula: a(n) = (1/4) +(n-1)*(1/2)

Answer:

Where's the graph kid sir?

Step-by-step explanation:

Answer:

The y-intercept on a sloped line is where the line crosses the y-axis. Taking a look at your graph, Find a point where the line crosses the y-axis.

Understanding:

This can be easily solved by using the distance formula which is

[tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} }\\[/tex]

[tex]d:[/tex] distance

[tex](x_{1},y_{1}):[/tex] coordinates of the first point, in our case it is [tex](1,-5)[/tex]

[tex](x_{2},y_{2}):[/tex] coordinates of the second point, [tex](4,-1)[/tex]

Solution:

[tex]d=\sqrt{[(4)-(1)]^{2}+[(-1)-(-5)]^2}\\=\sqrt{(3)^2+(4)^2}\\= \sqrt{9+16} \\=\sqrt{25}\\= 5[/tex]

The distance between the two points is 5.

Answer:

try -14!

Step-by-step explanation:

4x+188=6x+216

x=-14

Answer:

x = -14

Step-by-step explanation:

To start since the angles are congruent then they must be equal to each other, so we start by setting them equal to each other. The equation will be 4x + 188 = 6x + 216

Next we solve for x, subtracting 188 and 6x from each side. The new equation will be

-2x = 28

Then divide both sides by negative 2 to get x = -14.

Answer:

4.6%

Step-by-step explanation:

Cost of item __ sales tax

10 ___________0.46

50 __________ 2.30

5 ___________ 0.23

To obtain the sales tax % :

Sales tax % * cost of item = amount of sales tax

Let sales tax % = x

Using any of the rows in the table :

x * 10 = 0.46

x = 0.46 / 10

x = 0.046

x = (0.046) * 100% = 4.6%

When you catch up, the distance traveled is the same

Distance = rate x time

r = uncle's rate

30 min = 30/60 hr = uncle's time

25 min = 25/60 hr =  your time

Uncle's distance = Your distance

(r)(30/60) = (r + 10)(25/60)

(r)(1/2) = (r + 10)(5/12)

r/2 = 5r/12 + 50/12  

6r = 5r + 50

r = 50  

Uncle's rate = 50 mph

Your rate = 50 + 10 = 60 mph

Answer:

The answer is A. 48.7

Step-by-step explanation:

The approximate circumference of the circle is,

⇒ C = 48.7 cm

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

We have to given that;

A circle is shown in image.

And, Diameter of circle = 15.5 cm

Since, WE know that;

Circumference of circle is,

C = πd

Where, d is diameter of circle

Hence, The approximate circumference of the circle is,

⇒ C = 3.14 × 15.5

⇒ C = 48.7 cm

Thus, the circumference of the circle is,

⇒ C = 48.7 cm

Answer: THE PINK ONE (-2+6)

Step-by-step explanation:  WE DID THIS IN MATH SO I KNOW. IT'S THE PINK ONE! (-2+6)

Answer:

Step-by-step explanation:

Part A.

Expression [tex](100)^{\frac{1}{2}}[/tex] = 10

Because 100 = [tex](10)^{2}[/tex] and [tex][(10)^2]^{\frac{1}{2}}=10^1=10[/tex]

[Since, [tex](a^{2})^{\frac{1}{2}}=a^{2\times \frac{1}{2}}=a^1[/tex]]

Part B.

When simplified, the answer is RATIONAL.

[Since, 10 can be written as [tex]\frac{10}{1}[/tex]]

Answer:

A. 136 stars

B. 340 stars

Answer:

At 10 pm he counted 136 stars and at 12 pm he counted 340

Step-by-step explanation:

for 10 pm:

68 x 2

for 12 pm:

68 x 5

Solution :

Given :

n = 200, p = 80% = 0.8, q = 1 - p = 0.2

[tex]$\mu = np$[/tex]

  [tex]$= 200 \times 0.8 = 160$[/tex]

[tex]$\sigma= \sqrt{npq}$[/tex]

[tex]$\sigma= \sqrt{200 \times 0.8 \times 0.2}$[/tex]

   = 5.6569

a). x = 169.5

∴ [tex]$z = \frac{x- \mu}{\sigma}$[/tex]

  [tex]$z = \frac{169.5- 160}{5.6569}$[/tex]

     = 1.6794

[tex]$P(x \geq 170) = P(z>1.6794) = 0.0465$[/tex]

Therefore, probability that the stolen goods were not recovered in 170 robberies or more is = 0.0465

b). x= 149.5

   [tex]$z = \frac{x- \mu}{\sigma}$[/tex]

   [tex]$z = \frac{149.5- 160}{5.6569} = -1.8561$[/tex]

[tex]$P(x \geq 150) = P(z>-1.8561) = 0.9683$[/tex]

Therefore the probability that the stolen goods were not recovered in the 150 or in more robberies is = 0.9683
