Answer:

1•2n

Step-by-step explanation:

Given the sequence if numbers

1 2 , 1 4 , 1 6 , 1 8 , 1 10 , ...

You will see that 1 is common to all the numbers, the other part of the sequence are in arithmetic progression and they are

2,4,6,8,10...

The nth term of an AP is expressed as

Tn = a+(n-1)d

a is the first term

n is the number of terms

d is the common difference

a = 2

d = 4-2 = 6-4 = 8-6 = 2

Substitute into the formula

Tn = 2+(n-1)2

Tn = 2+2n-2

Tn = 2-2+2n

Tn = 2n

Hence the nth term of the sequence is 1•2n

Answer:

120.91 grams

Step-by-step explanation:

multiply the initial amount by the percent that will remain to the power of n-1, n being the term number, or how many days that have passed.

f(x)=1000(0.85)^14-1

The mass of the radioactive sample at the beginning of the 10th day of the experiment is 221.30 grams if the mass was decreasing by 14% per day.

During exponential decay, a quantity falls slowly at first before rapidly decreasing. The exponential decay formula is used to calculate population decline and can also be used to calculate half-life.

We have:

Mass of the substance = 1000 grams

Rate of decay = 14% per day = 0.14

Let's suppose the mass is m at the beginning of the 10th day of the experiment.

The equation for the exponential decay:

[tex]\rm E = m(1-r)^t[/tex]

[tex]\rm m = 1000(1-0.14)^1^0[/tex]

m = 1000×0.22130

m = 221.30 grams

Thus, the mass of the radioactive sample at the beginning of the 10th day of the experiment is 221.30 grams if the mass was decreasing by 14% per day.

44 degrees, or A is your answer.

Step-by-step explanation:

You know angle A which is 46 and angle C which is 90, now all you have to do is solve to find angle B.

90+46=136

All the sides have to add up to 180 so simply do 180 - 136.

That will get you 44.

  2.  K'(-1, -5)

  3.  (-3, 5), (3, 10), (-6, 8); translation left 2 and up 7

Step-by-step explanation:

2. The transformation is the one you have shown:

  (x, y) ⇒ (x, -y) . . . . reflection over the x-axis

You are given the coordinates for K and asked for K', the reflected point. Use the x- and y-values in the transformation formula:

  K(-1, 5) ⇒ K'(-1, -5) . . . . . . the y-coordinate is negated

It's that simple.

__

3. Same deal, different formula.

  (x, y) ⇒ (x -2, y +7)

  A(-1, -2) ⇒ A'(-1-2, -2+7) = A'(-3, 5)

  B(5, 3) ⇒ B'(5 -2, 3 +7) = B'(3, 10)

  C(-4, 1) ⇒ C'(-4 -2, 1 +7) = C'(-6, 8)

When constants are added to the coordinates, the transformation is a translation.

The x-values are decreased by 2, so that is a shift left by 2 units.

The y-values are increased by 7, so that is a shift up by 7 units.

The attachment shows the translated triangle (red). The translation vector (-2, 7) is shown as a black arrow. You will notice each triangle vertex is translated that length in that direction.

Answer:

The margin of error for a 95% confidence interval is of 2.18 hours.

Step-by-step explanation:

The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So

df = 100 - 1 = 99

95% confidence interval

Now, we have to find a value of T, which is found looking at the t table, with 99 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.95}{2} = 0.975[/tex]. So we have T = 1.984

The margin of error is:

[tex]M = T\frac{s}{\sqrt{n}}[/tex]

In which s is the standard deviation of the sample(square root of the variance) and n is the size of the sample.

In this question:

[tex]s = 11.5, n = 100[/tex]. So

[tex]M = T\frac{s}{\sqrt{n}}[/tex]

[tex]M = 1.984\frac{11}{\sqrt{100}}[/tex]

[tex]M = 2.18[/tex]

The margin of error for a 95% confidence interval is of 2.18 hours.

Answer:

The radius should be increased by 0.295 inches.

Step-by-step explanation:

Volume of a cylinder:

In a cylinder, in which the base has radius [tex]r[/tex], and the height is [tex]h[/tex], the volume is given by:

[tex]V = \pi r^{2}h[/tex]

In this question:

5 inch height, radius of 2.5 inches. So the volume is given by:

[tex]V = \pi (2.5)^2(5) = 31.25\pi[/tex]

We want to increase the volume by 25%.

So, the new volume is given by:

[tex]1.25*31.25\pi = 39.0625\pi[/tex]

With this volume, keeping the height, the radius should be of:

[tex]V = \pi r^{2}h[/tex]

[tex]39.0625\pi = 5\pi r^{2}[/tex]

[tex]r^{2} = \frac{39.0625}{5}[/tex]

[tex]r^{2} = 7.8125[/tex]

[tex]r = \sqrt{7.8125}[/tex]

[tex]r = 2.795[/tex]

The radius should be of 2.795 inches, which is an increase of 2.795 - 2.5 = 0.295 inches.

SO to find percent

just multiply the number by the percent

Remeber the percent means x/100

SO in this case 20/100 or 1/5

So you can just multiply 1/5*8 and get 1 3/5.

If you convert 3/5 into a decimal

3 divided by 5

that is .6

Answer:

3 hours was spent on labor

Step-by-step explanation:

Key skills needed: Creating an equation, Solving an equation

1) The total cost is 329.00 (or 329). The parts are 125.00 (or 125), and the labor is 68 per hour.

2) If we say h is the number of hours of labor, then we can create this equation --> [tex]68h[/tex] (or 68 multiplied by "h") 68h would be the cost of labor, and we need to find the number of hours (h) as a number.

3) We can create this equation --> [tex]329 = 125 + 68h[/tex]

--> This equation can be made as the total cost (329) is equal to the parts (125) and the labor (68h)

4) Subtract 125 from both sides to get 68h by itself

--> 329 - 125 = 204 so 204 = 68h

--> Divide by 68 on both sides (204 divided by 68 is 3)

--> This means that h is 3.

Therefore, the number of hours spent on labor is 3.

Answer:

Step-by-step explanation:

Total number = 150

Answer:

Ths sum of the first 38 terms is [tex]\frac{1,045}{2}=522.5[/tex]

Step-by-step explanation:

Arithmetic Sequences

They are identified because any term n is obtained by adding or subtracting a fixed number to the previous term. That number is called the common difference.

The equation to calculate the nth term of an arithmetic sequence is:

[tex]a_n=a_1+(n-1)r[/tex]

Where

an = nth term

a1 = first term

r   = common difference

n  = number of the term

The sum of n terms of the sequence is

[tex]S_n=\frac{n}{2}( a_1 + a_n)[/tex]

The common difference is found by subtracting two consecutive terms:

[tex]r=a_{n+1}-a_n[/tex]

Using the first two terms:

[tex]r=a_2-a_1=5-\frac{9}{2}=\frac{1}{2}[/tex]

Now we find the term n=38

[tex]\displaystyle a_{38}=\frac{9}{2}+(38-1)\frac{1}{2}[/tex]

[tex]\displaystyle a_{38}=\frac{9}{2}+\frac{37}{2}=\frac{46}{2}=23[/tex]

The sum is:

[tex]\displaystyle S_{38}=\frac{38}{2}( \frac{9}{2} + 23)[/tex]

[tex]\displaystyle S_{38}=19( \frac{9+46}{2})[/tex]

[tex]\displaystyle S_{38}=19( \frac{55}{2})= \frac{1,045}{2}=522.5[/tex]

Ths sum of the first 38 terms is [tex]\mathbf{\frac{1,045}{2}=522.5}[/tex]
