The first five terms of the sequence are 27, 22, 17, 12, and 7.

To find the first five terms of the sequence given by a₁=27 and d=-5,

we can use the formula for the nth term of an arithmetic sequence:

\(a_n=a_1+(n-1)d\)

Substituting the given values, we have:

\(a_n=27+(n-1)(-5)\)

Now, we can calculate the first five terms of the sequence by substituting the values of n from 1 to 5:

\(a_1=27+(1-1)(-5)=27\)

\(a_1=27+(2-1)(-5)=22\)

\(a_1=27+(3-1)(-5)=17\)

\(a_1=27+(4-1)(-5)=12\)

\(a_1=27+(5-1)(-5)=7\)

Therefore, the first five terms of the sequence are 27, 22, 17, 12, and 7.

Answer:

Step-by-step explanation:

1. sin 30 = x/16

   x= 16 sin 30

   x = 8

2. cos 60 = 22/x

   x = 22/cos 60

   x = 44

3. tan 45 = x/19

  x = 19 tan 45

   x= 19

4. tan 16 = x/13

   x = 13 tan 16

   x= 3.73

5. sin 54 = x/45

  x = 45 sin 54

  x= 36.41

6. sin 35 = z/23

 z =   23 sin 35

  z = 13.19

Answer:

  all real numbers

Step-by-step explanation:

Basically, you look for any values of x for which the function is not defined. There are none. So, the domain is "all real numbers."

__

The function is the product of a polynomial (x) and an exponential function (e^x). Each of those kinds of functions has a domain of "all real numbers". Multiplication is also defined for all real numbers, so there is nothing about this product that would restrict the domain.

The expression 400 + 0.1s represents her total weekly earnings.

An expression is written in the form of variables and constants separated by the operation of addition and subtraction. There are many types of expressions some of them are algebraic expression, trigonometric expression, logarithmic expressions, and many more.

Given Tasha earns $400 per week plus a commission of 10% on her weekly sales.

She also saves one-fourth of her earnings.

Assuming the amount she makes on sales is s.

∴ The expression that represents her total weekly earnings is,

Answer:

y = -4x + -3

Step-by-step explanation:

We know the slope-intercept form is y = mx + b, and m is the slope of the line, and b is the y-intercept. To find the slope, we need to divide the difference of the y coordinates by the difference of the x coordinates. We already have the slope listed there which is very helpful, so now all we need to do is find the y-intercept (where the line goes through the y axis). If we count the lines on the y axis starting from the origin and going downwards, we see that the line passes through at (0,-3), so the y-intercept is -3. Now we replace the variables with the correct numbers, and the answer would be y = -4x + -3. I hope this helped!! :]

Step-by-step explanation:

Put it in the calculator

the equation of the horizontal line passing through (-3, 4) is y = 4.

The equation of a horizontal line is of the form y = c, where c represents the y-coordinate of any point on the line. In this case, we are given that the line passes through the point (-3, 4). Since the line is horizontal, the y-coordinate remains constant for all points on the line.

Therefore, the equation of the horizontal line passing through (-3, 4) is y = 4. This means that no matter what x-value we choose, the y-value will always be 4.

In other words, all the points on this line will have a y-coordinate of 4.

Write the equation of the horizontal line that passes through (-3, 4).

The equation for the horizontal line that passes through a given point is y = b.

A horizontal line is a straight line that is parallel to the x-axis. The equation of a horizontal line is of the form y = c, where c is a constant. Since the line is horizontal, the value of y remains constant for all values of x. Therefore, the equation of a horizontal line passing through a given point (a, b) is y = b.

When the above is simplified using Boolean Algebra, we have F = x' + y' + w'xy.

We can simplify  the Boolean function F = xy'z' + xy'z+ w'xy +   w'x'y' + w'xy using the following Boolean Algebra rules.

Absorption - x + xy = x

Commutativity -  xy = yx

Associativity - x(yz) = (xy)z

Distributivity - x(y + z) = xy + xz

Using the above , we   have

F = xy'z' + xy'z+ w'xy + w'x'y' +   w'xy

= xy'(z + z') + w'xy(x + x')

= xy' +  w'xy

= (x' + y)(x' + y')  + w'xy

= x' + y' + w'xy

This means that the simplified expression is F = x' + y' + w'xy.

To determine the eligibility of each individual, their individual scores would need to be known and compared to the Mensa requirement.

a. The minimum Wechsler IQ test score that satisfies the Mensa requirement is approximately 130.

b. The probability that the mean score of 4 randomly selected adults on the Wechsler IQ test is at least 131 can be calculated using the Central Limit Theorem. Since the sample size is relatively large (n = 4), we can approximate the sampling distribution of the mean as normal.

Using the mean (μ = 100), standard deviation (σ = 15), and sample size (n = 4), we can calculate the z-score for a mean score of 131:

z = (131 - 100) / (15 / √4) = 4.20

Using the z-table or a statistical software, we can find the probability associated with a z-score of 4.20. This probability corresponds to the area under the normal curve to the right of the z-score.

c. We cannot conclusively determine that all 4 subjects are eligible for Mensa based solely on their mean score of 132, as the individual scores are lost. The mean score provides information about the group's performance on average, but it doesn't reveal the distribution or variation within the group. It's possible that some individuals in the group scored significantly higher or lower than the mean, affecting the eligibility of all 4 subjects.

Sum of interior angles is 180°:

Correct choice is B

let two integers be x and y

A.T.Q

x+y= -3

or, x= -3-y(i)

and xy= -18

or,(-3-y)y= -18[by(i)]

or,- -3y-y²= -18

or,-y²= -18+3

or, -y²= -15

or, y²=15

therefore y=✓15

from (i)

x= -3-✓15

y=√15

Answer:

Step-by-step explanation:

1. First, let's find the factors of -18

2. Next, we have to find which of the factors add up to -3.

3. Great! Now that we found the factors that result in a product of -18 and a sum of -3, the factors are 3 and -6.

The greatest integer in the new set is, 20.

What is mean, median and mode?

Adding the numbers together and dividing the result by the total number of numbers in the list yields the arithmetic mean. An average is most frequently used to refer to this. The middle value in a list that is arranged from smallest to greatest is called the median. The value that appears the most frequently on the list is the mode.

The given integers are, 6, 7, 8, 8, 11.

Mean = \(\frac{6 +7+8+8+11}{5} =\frac{40}{5} =8\)

Median = 8,

Mode = 8

Four integers are added to a group of integers data increases by 2 each.

Therefore, mode = 10.

In group of integers 10 must be 3 times, therefore Let fourth integer = x

Group of integers = 6, 7, 8, 8, 10, 10, 10, 11 and x.

Therefore, the new mean is, 10

Mean = \(\frac{6+7+8+8+10+10+10+11+x}{9} = 10\)

\(\frac{70+x}{9} = 10\\ 70+x=90\\x=90-70\\x=20\)

Therefore, 20 is the greatest integer in the new set.
