Identifying Types Of Angles: Check all relationships between angle 1 and angle 2.

musickatia [10]

#1. Vertical

#2. Adjacent, Complementary

#3. Adjacent, Linear Pair, Supplementary

---A linear pair forms a line, which is equal to 180 degrees

#4. Adjacent

#5. Vertical, Complementary

#6. Vertical, Supplementary

---There is a 90 degree angle within this problem. If one angle is 90 degrees, then they are all 90 degrees, which makes the sum of angle 1 and 2 = 180. So, they are supplementary.

Hope this helps!

7/2x+1/2x = 18+ 9/2x

chubhunter [2.5K]

Answer:

x=-36

Step-by-step explanation:

Add the 7/2x +1/2x to be 8/2x which means that it'll be 4x=18=9/2

then subtract 9/2x on both sides so itll be

$4x=18+\frac{9}{2} x$

-9/2x -9/2x

$-\frac{1}{2} x=18$ because if you do 8/2-9/2 it's -1/2

then multiply the reciprocal to both sides so

$(\frac{2}{-1})(-\frac{1}{2}x)=(\frac{2}{-1})(18)$

which then cancels out -1/2 and makes it

x=-36

The product of the first three terms of a geometric progression is 3375, and their sum is 65. Find the first term of this progre

artcher [175]

Answer:

5 or 45

Step-by-step explanation:

If the first term is "a" and the common ratio is "r", then the first three terms are ...

a, ar, ar²

Their product will be ...

a × ar × ar² = (ar)³ = 3375

ar = ∛3375 = 15

Their sum will be ...

a + ar + ar² = 65 = 15/r + 15 + 15r

Subtracting 15 and multiplying by r/5, we have the quadratic in r:

10r = 3 + 3r²

3r² -10r +3 = 0 . . . . in standard form

(3r -1)(r -3) = 0 . . . . factored

r = 1/3 . . or . . 3 . . . . values of r that make the factors zero

The first term is 15/r = 45 or 5

_____

The first three terms could be 5, 15, 45; or they could be 45, 15, 5.

Which of the following is true regarding the sequence graphed below?

Klio2033 [76]

Answer: The correct option is

(D) The sequence is not arithmetic because the terms do not have a common difference.

Step-by-step explanation: We are given to select the true statement regarding the sequence that is graphed in the figure.

From the graph, we see that some of the points are (1, 1), (2, 4), (3, 9), (4, 16), (5, 25).

That is, if we write the graphed points in terms of a sequence <a(n)>, then we get

$a(1)=1,\\\\a(2)=4,\\\\a(3)=9,\\\\a(4)=16,\\\\a(5)=25.$

The sequence <a(n)> will be arithmetic if the difference between the consecutive terms is equal. That is, the terms should have a common difference.

Now,

$a(2)-a(1)=4-1=3,\\\\a(3)-a(2)=9-4=6,\\\\a(4)-a(3)=16-9=7,\\\\a(5)-a(4)=25-16=9.$

This implies that the terms do not have a common difference and so the graphed function does not represent an arithmetic sequence.

Thus, the sequence is not arithmetic because the terms do not have a common difference.

Option (D) is CORRECT.
