In the given figure AB parallel to CD then value of x is?
Answer:
x = 45
Step-by-step explanation:
AB // CD,
∠AB0 + ∠COB = 180 {Co interior angles}
75 + ∠COB = 180
∠COB = 180 - 75 = 105
∠DOE =∠COB {Vertically opposite angles}
∠DOE = 105
In ΔDOE,
x + 30 + 105 = 180 {angle sum property of triangle}
x + 135 = 180
x = 180 - 135
x = 45

For the points P and Q, find the distance d(P,Q) of the segment PQ. (3,4) , ( 7,7)
Answer:
[tex]d=5[/tex]
Step-by-step explanation:
Distance Formula: [tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
Simply plug in the 2 coordinates into the distance formula to find distance d:
[tex]d=\sqrt{(7-3)^2+(7-4)^2}[/tex]
[tex]d=\sqrt{(4)^2+(3)^2}[/tex]
[tex]d=\sqrt{16+9}[/tex]
[tex]d=\sqrt{25}[/tex]
[tex]d=5[/tex]

given the following function list the first 4 terms
f (n) = 5 (n + 2)
Answer:
15,20,25,30
Step-by-step explanation:
f (n) = 5 (n + 2)
Let n=1
f (1) = 5 (1 + 2)
= 5(3) = 15
Let n=2
f (2) = 5 (2 + 2)
= 5(4) = 20
Let n=3
f (3) = 5 (3 + 2)
= 5(5) = 25
Let n=4
f (4) = 5 (4 + 2)
= 5(6)=30
Answer:
15, 20, 25, 30
Step-by-step explanation:
To calculate the value of a term, you plug in the term value into the equation, which, in this case, means replacing the n with the term number.
Term 1:
5 (1 + 2)
5 (3)
15
Term 2:
5 (2 + 2)
5 (4)
20
Term 3:
5 (3 + 2)

each term of a sequence is 2 more than the previous term. if the third term is 8 find the first five terms of the sequence
Step-by-step explanation:
T3=8
8=a+2d
where a is first term ,d is common ratio
8=a+2(2)
8=a+4
a=8-4
a=4
first term T1 is 4
T2=a+d
T2=4+2
T2=6
T4=a+3d
T4=4+3(2)
T4=4+6
T4=10
T5=a+4d
T5=2+4(2)
T5=4+8
T5=12

Step-by-step explanation:
1. Multiply all the multiplication problems (should look like this --> 16-7x+12-2-6+9x-4)
2. Calculate the sum or difference (should end up looking like this --> 16-7x+9x) and then into this (16 +2x)
Bringing us to the answer → 16 + 2x!

Mara found the length of time of an investment. The principal of the investment was $4,300, the interest rate was 6.2 percent, and the interest was $2,666. Mara made an error in her work.
I = p r t. 2666 = (4300) (0.062) t. 2666 = (266.6) t. StartFraction 266.6 over 2666 EndFraction = t. 0.1 = t.
well, 6.2% of 4,300 can't be over half. she has made a calculation error, and the real answer is (this is where the mistake was made) 4,300 * 0.062 (not 6.2, because percents are always divided by 100 to make them into a usable number), which is equal to $266.60.
Six less then a number is equal to ten
According to the information we can infer that the number is 16. So, 6 - 16 is 10.
What number does complete the operation correctly?Let's assume the number is represented by 'x'.
According to the given information, six less than a number is equal to ten. This can be expressed as:
x - 6 = 10To find the value of 'x', we can add 6 to both sides of the equation:
x - 6 + 6 = 10 + 6This simplifies to:
x = 16According to the information we can conclude that the number is 16. So, 6 - 16 is 10.

solve for y 5y-28=7(y=2) Simplify your answer as much as possible.
Answer: Y=7
Step-by-step explanation: if you have to find y then it’s
5y-28=7
+28+=+28 adding 28 to both sides to have y by itself -28+28=0 & 28+7=35
5y=35 then you divide by 5 on both sides
So it’s y= 7
