Type the correct answer in each box. if necessary, use / for the fractions bar(s).

I just took a screenshot of it, but I have no idea how to do this

Marianna [84]

Answer:

84°

Step-by-step explanation:

Solve for n. Note that the angle measurements of a circle will equal 360°. Set all the angles = 360°.

7n + 12 + 13n - 16 + 6n = 360

Combine like terms:

(7n + 13n + 6n) + (12 - 16) = 360

26n - 4 = 360

Isolate the variable, n. Note the equal sign, what you do to one side, you do to the other. First, add 4 to both sides:

26n -4 (+4) = 360 (+4)

26n = 360 + 4

26n = 364

Next, divide 26 from both sides:

(26n)/26 = (364)/26

n = 364/26

n = 14

Next, plug in 14 for n in the angle measurement, 6n:

6n = 6(14) = 84°

Note that these are central angles, which means that the arc's will be the same measurement as the angle's measurement.

arcBC = 84°

84° is your answer.

We probably couldn't go to all the stars because they're too far away. It would take a long time to get there.

Dvinal [7]

Answer:

The correct answer is B. Contain generalizations and contractions.

Step-by-step explanation:

A generalization occurs when a specific idea is applied to a general category, in simple terms it occurs if a person states something always occur because this person saw it once. In this case, generalization occurs as this person affirms all stars are too far away and thus it will take a long time to get to those stars, however not all stars are as far away as this person believes and this does not mean it will take a long time to get there as new technology can be created, thus, this statement is not true and need revision. On the other hand, contractions refers to the process of shortening words by putting them together, this can be seen in "couldn't" ( could + not) and "they're" (they + are), contradictions are not correct as they should not be used in formal language and be avoided, thus, contradictions also need to be revised.

How do you find the height of a parallelogram if you know the base and area?

ludmilkaskok [199]

You divide the area by the base because A = bh, so you would use the algebraic expression (A/B)=H

Question 8 (1 point)

AleksandrR [38]

Answer:

solution is x=3

Step-by-step explanation:

$logx-log3=log(x-2)$

apply log property

log a- log b= log a/b

$logx-log3=log(x-2)\\log (\frac{x}{3} )=log(x-2)$

we have log on both sides

so we remove the log and make the arguments equal

$\frac{x}{3} = x-2$

solve for x, multiply whole equation by 3

$x=3(x-2)\\x=3x-6\\x-3x=-6\\-2x=-6\\x=3$

now plug in 3 for x and check

$logx-log3=log(x-2)\\log3-log3=log(3-2)\\0=0$

solution is x=3

Convert x2 + y2 -4x = 0 to polar form.

Bingel [31]

Answer:

$r(r-4\cos \theta)=0$

Step-by-step explanation:

We are given the following equation:

$x^2 + y^2 -4x = 0$

We have to convert it into polar form.

We put

$x = r \cos \theta\\y = r\sin \theta$

Putting values, we get:

$x^2 + y^2 -4x = 0\\(r\cos \theta)^2 + (r\sin \theta)^2 - 4(r\cos \theta) = 0\\r^2(\cos^2 \theta + \sin^2 \theta) - 4r\cos \theta = 0\\r^2 - 4r\cos \theta = 0\\r(r-4\cos \theta)=0$

is the required polar form.
