The maximum height that the pendulum can reach will be 45 meters.
<h3>How to calculate the height?</h3>
It should be noted that the total energy at A should be equal to the total energy at B.
Therefore, this will be calculated thus:
1/2(14)² + 10(35) = 1/2(0)² + mgH
98 + 350 = 10H
448 = 10H
H = 448/10
H = 44.8 meters
H = 45 meters approximately

Answer:
53
Step-by-step explanation:
If cba is 37 degrees then dbe has to be 53 degrees. The bottom and top angle are obtuse so they are out of the question
Answer: " \frac{1}{4} gal /hr ; or, write as: " 0.25 gal/hr. " .
_______________
Step-by-step explanation:
_______________
This is a "unit rate" problem;
that is: we want to solve for a particular quantity per [single] unit.
_______________
→ in this case, per single "hour" ;
_______________
So we convert:
_______________
" 2 gal per 8 hours" ; to the correct number of:
_?_ gal per [single] hr.
_______________
{<u>Note</u>: "gal" refers to: "gallon(s)" ;
"hr" refers to: "hour(s)" .}.
_______________
→ " ![\frac{2 gal}{ 8 hr} = [\frac{2}{8}]](https://tex.z-dn.net/?f=%5Cfrac%7B2%20gal%7D%7B%208%20hr%7D%20%3D%20%5B%5Cfrac%7B2%7D%7B8%7D%5D)
gal / hr. " ;
_______________
→ " { 
[2÷2] / [8÷2] = 1/4 ;
_______________
So, the answer is:
→ " 
" ;
_______________
or: write as decimal:
→ " 
= (1 ÷ 4) = 0.25 " ;
_______________
write the answer as:
_______________
→ " 0.25 gal/hr. "
_______________
Or, when we had:
→ "2/8" gal/hr ;
_______________
Use calculator:
→ " 
= "2 ÷ 8" ;
= " 0.25 gal/ hr.
_______________
So: The correct answer is:
_______________
" \frac{1}{4} gal /hr ; or, write as: " 0.25 gal/hr. " ;
_______________

Answer:
45hours
Step-by-step explanation:
Given
Mary month earnings to be R(x)=13x+155
Josies monthly earning is given as Q(x)=9x+335
If Josie and Mary work to earn the same salary, then R(x) = Q(x)
13x+155 = 9x+335
subtract 155 from both sides
13x+155-155 = 9x+335-155
13x = 9x+180
subtract 9x from both sides
13x-9x = 9x+180-9x
4x = 180
x = 180/4
x = 45
Since x equals the number of hours worked by Josie and Mary, this means that Josie and Mary must work for 45hours to earn the same salary
Answer:
In general, the slope intercept form assumes the formula: y = mx + b.
m is the slope (lesson on slope ) mnemonic : 'm' means 'move'
b is the y -intercept ( lesson on the y-intercept ) mnemonic : 'b' means where the line begins.
Step-by-step explanation:
