Answer:

I believe a=22

Step-by-step explanation:

a=4+4+4+2+8

a=8+4+2+8

a=12+2+8

a=14+8

a=22

6 + 11 =

Step-by-step explanation:

We have to use the exponent laws to figure this out. When we are multiplying a number with the same bases, we just simply add the exponents. So it would look something like this:

[tex]=11^{8\ +\ -7\ +\ 3}[/tex]

eight plus negative seven equals one, plus three equals four.

So the simplified form will be 11⁴

a = 11

n = 4

Answer:

angle A

Step-by-step explanation:

Therefore angle A has a cosine of 3/5

According to the described situation, we have that:

The decision rule is:

The value of the test statistic is of z = -0.866.

The claim is:

"Forty percent or more of those persons who retired from an industrial job before the age of 60 would return to work if a suitable job were available"

At the null hypothesis, we consider that the claim is false, that is, the proportion is of less than 40%, hence:

[tex]H_0: p < 0.4[/tex]

We have a right-tailed test, as we are testing if a proportion is less/greater than a value. Since we are working with a proportion, the z-distribution is used.

Using a z-distribution calculator, the critical value for a right-tailed test with a significance level of 0.01 is of z = 2.327, hence, the decision rule is:

The test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

In which:

In this problem, the parameters are:

[tex]p = 0.4, n = 200, \overline{p} = \frac{74}{200} = 0.37[/tex]

Hence:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

[tex]z = \frac{0.37 - 0.4}{\sqrt{\frac{0.4(0.6)}{200}}}[/tex]

[tex]z = -0.866[/tex]

The value of the test statistic is of z = -0.866.

Answer:

all of them..

Step-by-step explanation:

-3+2=-1

-12+2=-10

-11+2=-9

-2+2=0

which are all less than 1

Step-by-step explanation:

we need to find the LCM, the least (or lowest) common multiple, of 3 and 4.

that means the smallest number that can be divided by 3 and by 4 without remainder.

and that is simply in our case 3×4 = 12.

so, every 12th day they will walk to the lake "together" (on the same day).

FYI - formality the LCM is found e.g. by prime factorization.

starting with the smallest prime number (2) both numbers are divided by the prime number, if there is no remainder. the quotient is then again divided by the prime number. if there is a remainder, then the next higher prime number is taken for the division.

this goes on until we get a quotient of 1.

the LCM is then the product of the longest streaks of the products of the same prime numbers.

example LCM of 56 and 50

56 ÷ 2 = 28 (0 remainder)

28 ÷ 2 = 14 (0 remainder)

14 ÷ 2 = 7 (0 remainder)

7 ÷ 2 has a remainder, so the next prime number (3)

7 ÷ 3 has a remainder, so the next prime number (5)

7 ÷ 5 has a remainder, so the next prime number (7)

7 ÷ 7 = 1 finished

50 ÷ 2 = 25 (0 remainder)

25 ÷ 2 has a remainder, so the next prime number (3)

25 ÷ 3 has a remainder, so the next prime number (5)

25 ÷ 5 = 5 (0 remainder)

5 ÷ 5 = 1 finished

the longest streaks of prime number products :

2×2×2 = 8

5×5 = 25

7 = 7

the LCM = 8×25×7 = 1400

please consider, this is NOT 56×50 = 2800.

the LCM is not automatically just the product of both numbers. this product is a common multiple, true, but not always the smallest.

in our case here with 3 and 4

3 ÷ 2 has a remainder, so the next prime number (3)

3 ÷ 3 = 1 finished

4 ÷ 2 = 2 (0 remainder)

2 ÷ 2 = 1 finished

the longest prime number product streaks :

2×2 = 4

3 = 3

the LCM = 4×3 = 12

so, in this case the LCM is the direct product of both numbers.

Answer:

The slope is undefined.

Step-by-step explanation:

The slope of a line is its relationship between its change in verticalness and its change in horizontalness. In layman's terms, we call it rise over run. Slope can be useful for many things: to show how steep a line is, to write a line in slope-intercept form (y = mx + b), etc.

Recall that a line only needs two points to be formed. That's why slope matters so much. With lines, we only care about its steepness and its position on the coordinate plane, so slope knocks out one of those criteria.

One way to find slope is to use the definition of slope, the change in verticalness (y) divided by the change in horizontalness (x):

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]

where m is the slope of the line;

and x1, y1, x2, and y2 are coordinates for points (x1, y1) and (x2, y2).

So let's use what we now know to solve the problem.

Since (-5,8) and (-5,9) are two points, they can form a line. So I can say that x1 = -5, y1 = 8, x2 = 5, and y2 = 9. Now, let's plug these numbers into the formula.

[tex]m=\frac{-9-8}{-5-(-5)}[/tex]

[tex]m = \frac{-17}{0}[/tex]

"Wait, what's going on? I thought I can't divide by 0." - You

Yes, exactly. But what we have here is a special case of a line, nothing more. Let me explain.

Lines don't always have a natural number for a slope, like m = 1. There are two special lines that deviate from the norm: horizontal lines and vertical lines.

Horizontal lines have a slope of zero. This is because they change in x, but not in y. So y appears as 0 in the formula: 0/x = 0. That's why horizontal lines have a slope of zero. They are usually written as y = C where C is some constant.

Vertical lines have an undefined slope. We're dealing with this type of line for our problem. They change in y, but not in x. So x appears as 0 in the formula: y/0 = undefined. We simply cannot divide by zero. That's why vertical lines have undefined slopes. They are usually written as x = C where C is some constant.

So there you go. (-5, 8) and (-5, -9) form a vertical line that has an undefined slope. And if you really want to know the equation for this line, it's x = -5.

Answer:

$654.32 (to the nearest cent)

Step-by-step explanation:

Compound interest is based on the principal amount and the interest that accumulates on it in every period.

Monthly Compound Interest formula:

[tex]CI = P(1 + (\frac{r}{n} ))^{nt} - P[/tex]

where:

P = principal amount

r = annual interest rate (as a decimal)

n = frequency or number of times the interest is compounded annually

t = overall tenure in years

So for this problem:

P = 500

r = 9 ÷ 100 = 0.09

n = 12

t = 3

Therefore,  

Compound Interest = [tex]P(1 + (\frac{r}{n} ))^{nt} - P[/tex]

                                = 500 x (1 + (0.09/12))^(12 x 3) - 500

                                = 500 x (1.0075)^36 - 500

                                = 154.3226855

So the value of the $500 investment = principal amount + compound interest

= 500 + 154.3226855

= $654.32 (to the nearest cent)

Step-by-step explanation:

1. sin 21 = x/12

x = 12*.35=4.2

2. cos 56 = 10/x

x = 10/cos 56 = 11.72

3. tan 32 = x/7

x = 7*tan32 = 4.6

4. tan 35 = 5/x

x = 5/tan 35 =10.55

5. tan 61 = 3/x

x = 3/tan 61 = .8

Check the picture below.

so by graphing those two, we get that little section in gray as you see there, now, x = 6  is a vertical line, so we'll have to put the equations in y-terms and this is a washer, so we'll use the washer method.

[tex]y=4x\implies \cfrac{y}{4}=x\qquad \qquad y=2\sqrt{x}\implies \cfrac{y^2}{4}=x~\hfill \begin{cases} \cfrac{y}{4}=x\\\\ \cfrac{y^2}{4}=x \end{cases}[/tex]

the way I get the radii is by using the "area under the curve" way, namely, I use it to get R² once and again to get r² and using each time the axis of rotation as one of my functions, in this case the axis of rotation will be f(x), and to get R² will use the "farthest from the axis of rotation" radius, and for r² the "closest to the axis of rotation".

[tex]\stackrel{R}{\stackrel{f(x)}{6}-\stackrel{g(x)}{\cfrac{y^2}{4}}}\qquad \qquad \stackrel{r}{\stackrel{f(x)}{6}-\stackrel{g(x)}{\cfrac{y}{4}}}~\hfill \stackrel{R^2}{\left( 6-\cfrac{y^2}{4} \right)^2}-\stackrel{r^2}{\left( 6-\cfrac{y}{4} \right)^2} \\\\\\ \stackrel{\textit{doing a binomial expansion and simplification}}{3y-3y^2-\cfrac{y^2}{16}+\cfrac{y^4}{16}}[/tex]

now, both lines if do an equation on where they meet or where one equals the other, we'd get the values for y = 0 and y = 1, not surprisingly in the picture.

[tex]\displaystyle\pi \int_0^1\left( 3y-3y^2-\cfrac{y^2}{16}+\cfrac{y^4}{16} \right)dy\implies \pi \left( \left. \cfrac{3y^2}{2} \right]_0^1-\left. y^3\cfrac{}{} \right]_0^1-\left. \cfrac{y^3}{48}\right]_0^1+\left. \cfrac{y^5}{80} \right]_0^1 \right) \\\\[-0.35em] ~\dotfill\\\\ ~\hfill \cfrac{59\pi }{120}~\hfill[/tex]

What is the trigonometric ratio?

Trigonometric ratios are the ratios of a right triangle's sides. The sine (sin), cosine (cos), and tangent (tan) are three often used trigonometric ratios. There are other trigonometric ratios which are reciprocals of these ratios.

Trigonometric ratios can be computed either using the provided acute angle or by calculating the ratios of the right-angled triangle's sides.

1. Trigonometric function:

 cos (π) = -1

2. Inverse function :

 π = arccos( -1 )  

We can see that the inverse function of "cos" is "arccos" and viceversa

Hey there mate :)

As per question, AB + BC = AC are the sides of a triangle.

=> AB + BC = AC

( AC is hypotenuse and AB and BC are remaining two sides )

=> (x + 16) + (4x + 11) = 77

(These are the given values of each side such as [x+16]=AB ; BC=[4x+11] and AC=77)

=> 5x = 77 - 27

=> 5x = 50

=> x = 50/5

=> x = 10

( Now these above steps are the continuing solving processes of given values)

=> AB = x + 16

(Previously we got value x and now substitute its value)

=> AB = 10 + 16

=> AB = 26

(Now these are the remaining solving processes)
