what will be the 40th term in the sequence defined by an=-12+4(n-2)

Answers

Answer 1

Answer:

140

Explanation:

an=-12+4(n-2)

an=-12+4([40]-2)

an=-12+4(38)

an=-152-12

an=140

Answer 2

The 40th term in the sequence defined by aₙ= -12+4(n-2) is 140

using AP formula,

aₙ = a + (n - 1)d

where

a = first term

d = common difference

n = number of terms

Therefore,

aₙ = -12 + 4(n-2)

n = 40

a₄₀ = -12 + 4(40 - 2)

a₄₀ = -12 + 4(38)

a₄₀ = -12 + 152

a₄₀ = 140

The 40th term of the sequence is 140.

use an identity to solve the equation on the interval [0,2pi) sin x cos x = -1/4 x=

Answers

Answer:

The solution of the given equation is    x = 105 °∈ ( 0 , 2pi)

Step-by-step explanation:

Step(i):-

Given equation is sin x cos x = -1/4

                           [tex]2(2sinxcosx) = -1[/tex]

we know that trigonometry formula

                             2 sin x  cos x = sin 2x

                            2 ( sin 2 x) = -1

                                sin2x = -1/2

Step(ii):-

                            sin2x =    [tex]\frac{-1}{2} = sin (\pi +\frac{\pi}{6}[/tex]

                 sin2x = sin 210                       2x = 7π/6                       2x = 210°                                x = 105 °The solution of the given equation is    x = 105 °∈ ( 0 , 2pi)

The area of the rectangle flower bed shown is
20.4 square meters. How many meters of edging are needed to go around the flower bed?

Answers

Answer:

I think 5.4

Step-by-step explanation:

Take it and divide by the number of sides

The Perimeter of rectangle is 27.4 m

What is Area of rectangle?

The area of rectangle is product of its length to tis width.

So, Area of rectangle = length  x width

Given:

Area of the flower bed = 20.4 square meters.

length = 12 m

As a rectangle, its area be

A = l x w

20.4 = 12 w

w= 20.4/ 12

w= 1.7

Now, Perimeter of rectangle

= 2( l + w)

= 2( 12+ 1.7)

= 27.4 m

Hence, the Perimeter of rectangle is 27.4 m

The area of a sector of a circle is:

A = π r² Ф/360

A = π (9)² 60/360

A = π 81 * 1/6

I feel it could be AAS since both angles could be alternate interior but it could also be SAS so could someone help please?

Answers

Answer: D) Side-Angle-Side  (SAS)

Check out the diagram below. Note the color coding to see how the angles and sides correspond to the given information. We aren't given RT = RT, but we use the reflexive property in this case. The angles are between the sides so we use SAS.

We don't have enough information to determine anything about the other angles, so we cannot use AAS or ASA. Also, recall that SSA is not a valid congruence theorem. Luckily the angle is between the sides so we don't have to worry about SSA.

IQ test scores are standardized to produce a normal distribution with a mean of = 100 and a standard deviation of = 15. Find the proportion of the population for the following IQ score. For your answer, convert each proportion into a percentage whose value is computed to 2 decimal places. Sketch a distribution to help you visualize the problem. IQ score greater than 135

Answers

Answer:

0.01

Step-by-step explanation:

Using the z score formula

z = (x-μ)/σ,

where x is the raw score = 135

μ is the population mean = 100

σ is the population standard deviation = 15

z = 135 - 100/15

z = 2.33333

P-value from Z-Table:

P(x<135) = 0.99018

P(x>135) = 1 - P(x<135)

P(x > 135) = 1 - 0.99018

= 0.0098153

Approximately to 2 decimal places

= 0.01

Therefore, the proportion of the population for the following IQ score of 135 is 0.01

this is the correct answer i got on my assignment-------

The system of inequalities can model Gabrielle’s situation is x + 2y ≤ 20

and 3x + 2y ≤ 21.

What are inequalities?

The relation between two expressions that are not equal, employing a sign such as not equal to’, >greater than’, or < less than’.

It follows from the task content, that the inequalities which can be used to model Gabrielle's situation be determined.

By setting variables as follows; batches of brownies = x and batches of cookies = y

Brownie:

Sugar = 1 cup

Eggs = 2

x + 2y ≤ 20

Cookie:

Sugar = 3 cups

Eggs = 2

3x + 2y ≤ 21
