Can Anybody Tell Me Whats Going On Here?

Answers

Answer 1

Step-by-step explanation:

We are given a theta degree measure of sin in a specific interval. We are asked to find half of that degree measure.

The interval it ask us to find it in is between 2 pi and 5 pi over 2.

That is 360 degrees to 450 degrees. If you use reference angles, that is between the 0 degrees and 90 degrees. So that means our measure is going to be in the 1st quadrant.

Replace x with theta

[tex] \sin( \frac{x}{2} ) = + - \sqrt{ \frac{1 - \cos(x) }{2} } [/tex]

We dont know cos x but we can use the pythagorean trig theorem to find cos x.

[tex] \sin {}^{2} (x) + \cos {}^{2} (x) = 1[/tex]

[tex] \sin {}^{2} ( \frac{4}{5} ) + \cos {}^{2} (x) = 1[/tex]

[tex] \frac{16}{25} + \cos {}^{2} (x) = 1[/tex]

[tex] \cos {}^{2} (x) = 1 - \frac{16}{25} [/tex]

[tex] \cos {}^{2} (x) = \frac{9}{25} [/tex]

[tex] \cos(x) = \frac{3}{5} [/tex]

Cosine in 1st quadrant is positive so 3/5 is cos x.

Replace 3/5 for cos x.

[tex] + - \sqrt{ \frac{1 - \frac{3}{5} }{2} } [/tex]

[tex] + - \sqrt{ \frac{2}{10} } [/tex]

The answer is

[tex] + - \sqrt{ \frac{2}{10} } [/tex]

A sequence is given by the function an = 4an-1 . If a1= 3, what is the value of a6 ?

Answers

Answer:

3072

Step-by-step explanation:

a1 = 3

an = 4 an-1

so a2 = 4 (a1) = 4*3 = 12

a3 = 4 a2 = 4(12) = 48

a4 = 4*a3 =4*48 =192

a5 =4a4 = 4*192 =768

a6 =4*a5 =4*768 = 3072

What is the relationship between factoring and distribution?

Answers

Answer:

UwU

Step-by-step explanation:

Use the distributive property to factor a monomial out of a polynomial. Factors are numbers that multiply together to produce another number. For example, 2 and 10 are factors of 20, as are 4 and 5 and 1 and 20. Factoring is the process of breaking a number down into its multiplicative factors.

Answer: Factoring is the opposite of using the distributive property to multiply. If you had: 7(3x + 8), you would distribute the 7 and multiply it both both terms. Factoring reverses that process.

To stich a shirt, 2m 15cm cloth is needed. Out of 40m cloth,how many shirts can be stiched and how many will remain?

Answers

Answer:

18 shirts can be made and 130 cm of clothes will remain unstitched.

Step-by-step explanation:

Given that,

Total length of the cloth = 40 m = 4000 cm

Amount needed to stitch a shirt = 2m 15cm = 215 cm

Now dividing 4000 by 215 to get the number of shirts that can be stitched and no. of shirts remain. After dividing, we get quotient as 18 and remainder as 130.

So, 18 shirts can be made and 130 cm of clothes will remain unstitched.

A performing arts group has 23 members and adds 2 members per
month. Write an equation in slope-intercept form to represent the number
of members y in x months.

Answers

y=2x+23

2x is the for the number of people added every month and 23 is for the number you start with

The equation in slope-intercept form to represent the number of members y in x months is : y = 2x + 23

What is the equation?

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

In slope-intercept form, an equation of a line is represented as y = mx + b, where m is the slope (or rate of change) and b is the y-intercept (or the point at which the line crosses the y-axis).

Let's represent x is the number of months and y is the number of members.

The number of members y in x months is a linear function of the number of months, with a slope of 2 (the number of members added per month) and a y-intercept of 23 (the number of members at the beginning).

Thus, the equation in slope-intercept form to represent the number of members y in x months is : y = 2x + 23

Barrett is comparing the membership fees for two museums.The art museum charges a one-time fee of $8.25 plus $2.25 per month. The science museum charges a one-time fee of $10.75 plus $3.50 per month. How much does Barrett save after m months by joining the art museum instead of the science museum?

Answers

Answer:

$2.50+$1.25 times M

Step-by-step explanation:

$10.75-$8.25=$2.50

$3.50-$2.25=$1.25

$2.50+$1.25=$3.75

As only one-time fee, we cancel out it, then only add on the per-month fee, which is $1.25 every month.

CARL BUYS 4 ONT PINT CARTONS OF MILK. HE BUYS LESS JUICE THAN MILK. WHICH COULD BE THE AMOUNT OF JUICE.

Answers

Answer:

0 pints ≤ J ≤ 4 pints

Where J is the amount of juice that Carl bought.

Step-by-step explanation:

Here we need to learn how to use the inequality symbols.

Let's define each one of them:

A < B   (A is strictly smaller than B)

A > B  (A is strictly greater than B)

A ≤ B (A is smaller than or equal to B)

A ≥ B  (A is greater than or equal to B)

A ≠ B  (A is different than B)

Ok, in this case, we know that Carl buys 4 one-pint cartons of milk.

Then the total amount of mil that he buys is 4 times one pint, this is:

4*1 pint = 4 pints

He has 4 pints of milk.

And we know that he buys less juice than milk, then if J represents the amount of juice that he bought, we need to have:

J < 4 pints

This means that the amount of juice that he bought is smaller than the quantity of milk that he bought (4 pints)

If we want to be more correct, we should write:

0 pints ≤ J ≤ 4 pints

Here we say that J needs to be a positive number (we can't buy a negative quantity of juice)

Finding a GPA is just like finding an average, you add up all of the different outcomes and divide it by the total amount of outcomes and you will get the average. You also need to know how many points each letter grade is worth. It is normally A=4.0 B=3.0 C=2.0 D=1.0 and F=0. In this case here is what you will add,

3+4+3+2=12
