Answer:
1: The one vertical from 104° is 104°
2:The one near the corner is 20°
3: The two angles right next to 104° are 76°
Step-by-step explanation:
1: Vertical angle are always equal to each other.
2: All sides of the triangle must equal 180° in all. If you add 56° + 104° it equals 160°. Now subtract 180° - 160°. You get 20°.
3: All straight angles equal 180° in all. So, if you subtract 180° from 104° you will get 76°. And again, these two angles are vertical so they will both be 76°.

Answers
Answer: 8 1/4 miles
Step-by-step explanation:
I think your question isn't well written and should be:
Nathan jogged 2 1/4 miles on Monday. On Wednesday, he jogged 3 1/3 miles and on Friday, he jogged 2 2/3 miles. How far did Nathan jog altogether?
This will be:
= 2 1/4 + 3 1/3 + 2 2/3
= 2 3/12 + 3 4/12 + 2 8/12
= 7 15/12
= 7 + 1 3/12
= 8 3/12
= 8 1/4 miles

Rewrite with only sin x and cos x.
sin 3x - cos x
Answers
Answer:
sin (3 x) - cos (x)=
= sin (2x + x) - cos (x)=
= sin 2x * cos x + cos 2 x * sin x - cos x = ( using additional formulas )
= 2 sin x cos² x + ( cos² x - sin² x ) sin x - cos x =
= 2 sin x cos² x + ( 1 - sin² x - sin² x ) sin x - cos x =
= 2 sin x cos² x + ( 1 - 2 sin² x ) sin x - cos x =
= 2 sin x cos² x + sin x - 2 sin³ x - cos x

Jade spent ⅓ of her math homework time working on word problems. What fraction of an hour did she spend working on word problems?
Answers
Answer:
If total maths hw time = 90 minutes, time spent on word problems = 1/2 hour
Step-by-step explanation:
Let the time available for maths homework be = 90 minutes. It is equal to 1.5 hour (as 1 hour = 60 minutes, 0.5 hour = 30 minutes).
1/3rd of maths homework time, ie 1/3rd of 90 minutes = 30 minutes, is used in doing word problems. These 30 minutes correspond to half (1/2 or 0.5) of an hour, as 1 hour = 30 minutes.

A line that is parallel to the line y=3x-8 and passes through the point (-1,6)
The equation of the parallel line is...
Answers
Answer:
y = 3x + 9
Step-by-step explanation:
If the line is parallel, that means it will have the same slope. So, the line will also have a slope of 3.
Using y = mx + b, plug in the slope and given point, and solve for b:
y = mx + b
6 = 3(-1) + b
6 = -3 + b
9 = b
Plug in the slope and b into y = mx + b
y = 3x + 9
So, the equation of the parallel line is y = 3x + 9

5. 44
6. 53
7. 62
8. 71
9. 80
Answer:
answers are below
Step-by-step explanation:
i don't know if you need an explicit or recursive rule so i'll include them both.
Given Info:
Sequence: 8, 17, 26,...
f(1) = 8
Find the common difference (d)
17 - 8 = 9
26 - 17 = 9
=> Common difference (d) = 9
Explicit rule: f(n) = f(1) + d(n-1)
=> f(n) = 8 + 9(n-1)
Recursive rule: f(n) = f(n-1) + d
=> f(n) = f(n-1) + 9
FINAL ANSWERS:
The explicit rule is: f(n) = 8 + 9(n-1)
The recursive rule is: f(1) = 8; f(n) = f(n-1) + 9
hope this helps and is right :)
