Use the fact that the bacteria is doubling every five minutes. What fraction of the bottle was full at 11:20am?

Answer:

0

Using scientific notation, considering that Thailand has the larger population, the power of 10 that should be on the label is of 7.

A number in scientific notation is given by:

[tex]a \times 10^b[/tex]

In this b is the power of 10 and the base a is in the following interval:

[tex]a \in [1, 10)[/tex].

In this problem, considering that both Thailand and Peru population's have exponent 7, and Panama's population is of [tex]4 \times 10^6 = 0.4 \times 10^7[/tex], the power of 10 that should be on the label is of 7.

Answer:

Step-by-step explanation:

Answer:

Area: 10.7521 cm

Circumference: 11.62389 cm

________________________________________________________

Area, A, will equal the formula of [tex]\pi r^2[/tex], so we must find the value and split that up. Diameter, d is equal to 2r. Let's solve.

[tex]A = \pi r^2[/tex]

[tex]d = 2r[/tex]

Now, make an equation combining like terms.

[tex]A = \frac{1}{4} \pi d^2[/tex]

This equation means to multiply those terms together. Since the diameter is 3.7, d is 3.7

[tex]\frac{1}{4} * \pi * 3.7 = 10.8(estimate)~cm[/tex]

Let's move on to circumference. On we go!

________________________________________________________

With circumference, it is very similar to what you just did to find area(A). You must again, set up these terms and make an equation out of them. C(circumference) is going to be equal to [tex]\pi r[/tex], notice how it does not say squared([tex]^2[/tex]) at the end now.

[tex]C = \pi r[/tex]

And diameter, you guessed it, will be 2r.

[tex]d = 2r[/tex]

Now, combine the like terms into an equation.

[tex]C = \pi d[/tex] pi times diameter(3.7)

[tex]\pi * d(3.7) = 11.6~cm[/tex]

Now that the problem is done, we move on to review.

________________________________________________________

We learned how to solve for circumference and area using diameter.

Answer:

Step-by-step explanation:

A=l x w

You would set the formula up like this:

A = (x - 5)(x - 6)

To solve this you would distribute. Starting at the x in (x - 5), you multiply it by the x in the second pair of parentheses, giving you x^2. Then, multiply the first x by -6, which gives you -6x. Once you've multiplied that first x by everything in the second set of parentheses, you move on to the second term, -5. You now multiply -5 by x, giving you -5x. And lastly, multiply -5 by -6, giving you positive 30(two negatives make a positive).

At this point you have:

A = x^2 - 6x - 5x + 30

The next step is to add like terms, the only ones here being -6x and -5x, which gives you -11x:

A = x^2 - 11x + 30

Being your final answer

I hope this helps you :)

Answer:

[tex]-13x-23[/tex]

Step-by-step explanation:

Given sequence:  [tex]x-9, -x-11, -3x-13[/tex]

Therefore,

General form of an arithmetic sequence: [tex]a_n=a+(n-1)d[/tex]

(where a is the first term and d is the common difference)

To find the common difference, subtract a term from the next term:

[tex]\begin{aligned}d & =a_2-a_1\\ & =(-x-11)-(x-9)\\ & = -x-11-x+9\\ & = -2x-2\end{aligned}[/tex]

Therefore,

[tex]a_n & =(x-9)+(n-1)(-2x-2)[/tex]

To find the 6th term, input n = 6 into the equation:

[tex]\begin{aligned}\implies a_6 & =(x-9)+(6-1)(-2x-2)\\ & = (x-9)+7(-2x-2)\\ & = x-9-14x-14\\ & = -13x-23\end{aligned}[/tex]

Answer:

Answer:

y = x/2 +9/2

Step-by-step explanation:

Answer:

y = x/2 +9/2

Step-by-step explanation:

y = -2x - 6.

The equation of the line perpendicular to the above equation has a slope 1/2

The equation of a slope is

y2-y1/x2-x1 = 1/2

To form an equation of the line we chose a point that lies on the graph which is perpendicular to y = -2x - 6 and an arbitrary point (x,y)

A point is given us already and that point is (3, 6).

Tie all together to compute the slope we have;

y-6/x-3 = 1/2

2(y-6) = x-3

2y-12= x-3

2y = x-3+12

2y= x+9

Dividing through by 2 we have

y = x/2 +9/2

y = x/2 + 4.5

$ 1349.746624

Step-by-step explanation:

The volume of a cylinder

The formula for calculating the volume of a cylinder is expressed as:

V=πr²h

where:

r is the radius

h is the height

Given the following parameters

r = d/2 = 1.5/2 = 0.75ft

h = 30ft

Get the volume of the cylinder

V=π(0.75)²(30)

V= 53.0144...ft³

If the wod costs $25.46 per cubic foot, hence the cost of the wood will be 53.0144*25.46 = $ 1349.746624

Answer:

129

Step-by-step explanation:

180-51= 129

129 is corresponding with x

and corresponding angles are equal

so 129 is the answer

Answer:129

Step-by-step explanation:

Because of the rule of alternate exterior angles the angle to the right of angle X would also be 51 and since we know a straight line is 180 degrees we will subtract the angle we know from 180 and you get 129 as your answer.
