Answer:
10 2/5 meters long
Step-by-step explanation:
first turn 20 4/5 into an improper fraction (104/4) then multiply that by 1/2 and you get 104/10 but simplify it to 10 2/5
Hope this helps!
(f-g)(x) = x²+6x - (7-x)
(f-g)(x) = x² + 6x - 7 + x
(f-g)(x) = x² + 7x - 7
(f-g)(9) = 9² + 7*9 - 7
(f-g)(9) = 81 + 63 - 7
(f-g)(9) = 137
Two factors of 64 that add up to 12 are 8 and 4.
8 x 8 is 64 so its a factor of 64
16 x 4 is 64 so its a factor of 64
8 + 4 = 12
Answer:
Step-by-step explanation:
Using the slope concept, it is found that the maximum length of the seesaw is of 1.73 meters.
<h3>What is a slope?</h3>
The slope is given by the <u>vertical change divided by the horizontal change</u>, and it's also the tangent of the angle of depression.
In this problem:
- The vertical change is of 1 m.
- The horizontal change is the length l.
Hence:
tan(30º) = 1/l
l = 1/tan(30º)
l = 1.73.
