Answer:
[tex]\frac{T^{2} g}{4\pi ^{2} } =L[/tex]
Step-by-step explanation:
Hey there,
[tex]T=2\pi \sqrt{\frac{L}{g} }\\\frac{T}{2\pi } =\frac{2\pi \sqrt{\frac{L}{g} } }{2\pi } \\\frac{T}{2\pi } =\sqrt{\frac{L}{g} } \\(\frac{T}{2\pi }) ^{2} =\frac{L}{g} \\\frac{T^{2} }{4\pi ^{2} } =\frac{L}{g} \\[/tex]
Use cross multiplication
[tex]T^{2} g=4\pi ^{2} L\\\frac{T^{2} g}{4\pi ^{2} } =\frac{4\pi ^{2} L}{4\pi ^{2} } \\\\\frac{T^{2} g}{4\pi ^{2} } =L[/tex]

Answer:
41.53333
Step-by-step explanation:
The answer is a decimal, and not a whole number because 623 is not divisable by 15. But if we we're to round 41.53 by the nearest tenth, your new rounded number would be: 42.

What is the solution for the system of equations 2x+3y=9y=x+8
Answers
The solution of the system of equations 2x+3y=9 and y=x+8 is x = -3 and y = 5.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that the two equations are 2x + 3y = 9 and y = x + 8. The value of x and y is calculated as:-
2x + 3y = 9
y = x + 8
Solve the equations as;-
2x + 3y = 9
-2x + 2y = +16
___________
5y = 25
y = 5
y = x + 8
x = 8 - 5
x = 3
Therefore, the solution of the system of equations 2x+3y=9 and y=x+8 is x = -3 and y = 5.

Look at the two equations: ( look at picture is you don't understand)
-3x + 6 = 21
-3x + 6 < 21
Which statement best describes the process used to solve the equations?
A.) In both cases, subtract 6 from both sides, but reverse the inequality sign when doing that for the inequality.
B.) In both cases, divide by -3 on both sides, but reverse the inequality sign when doing that for the inequality.
C.) The process is exactly the same for solving the equation and solving the inequality.
D.)The process for solving the equation is entirely different from solving the inequality.
Answers
Answer:
I believe it's A) "In both cases, subtract 6 from both sides, but reverse the inequality sign when doing that for the inequality."
Step-by-step explanation:
I say this because that's essentially the first step when solving both an equation and inequality.
(In case you were wondering, the next step would be to divide -3 on both sides, in order to get x by its self.)
Hope this helps :)

Step-by-step explanation:
The law of cosines can be used to find the missing side.
l² = m² +n² -2mn·cos(L)
l² = 8² +2.8² -2(8)(2.8)cos(103°) ≈ 81.9178

A family has two cars. The first car has a fuel efficiency of 35 miles per gallon of gas and the second has a fuel efficiency of 25 miles per gallon of gas. During
one particular week, the two cars went a combined total of 1925 miles, for a total gas consumption of 65 gallons. How many gallons were consumed by each of
the two cars that week?
Answers
Let x = gallons consumed by car 1
Let y = gallons consumed by car 2
We set up our equations:
35x+40y = 1850 eq1
x+y = 50 eq2
Substituting eq 2 into eq 1,
35x+40(50-x) = 1850
35x+2000-40x = 1850
-5x+2000 = 1850
-5x = -150
x = 30
Substitute value of x into eq 2.
x+y = 50
30+y = 50
y = 20
Car 1 consumes 30 gallons of gas.
Car 2 consumes 20 gallons of gas.

What are the rate of change and the initial amount? Explain what the rate of change and the initial amount mean for this particular situation.

Answers
Answer:
1) 5/1 is the slope, and 10 is the y intercept.
2) Inital amount is the y intercept, and 10 is the rate of change.
3) Should be easy from there! Just graph (0,10), and go up 5, right 1, and repeat.
Step-by-step explanation:
This is in slope intercept form! Where 5 is the slope, and 10 is the y intercept. The rate of change is another way of saying slope, and the inital amount is your starting value, or y intercept.
Find the inequality represented by the graph in the picture below
Answers
Answer:
[tex]y \geq2x - 5[/tex]
Step-by-step explanation:
First off, we can tell that the line has a positive slope because it's going upwards to the right. To find the slope of the line exactly, we will start at the first given point and count the units until we get to the next point.
(Remember that slope is written as rise/run.)
So the slope is 2/1 or just 2.
Next, we can tell that the y-intercept is -5, because that's where the line crosses the y-axis.
Additionally, since the line is solid, the inequality sign will either be the "greater than or equal to" sign, or the "lesser than or equal to" sign. In order to tell which one to use, we will look at the shaded area. Since the shaded area is above the line, y will be "greater than or equal to" the line.
So to put it together: The line written in slope-intercept form, is
[tex]y \geq2x - 5[/tex]
Hope this helps you :)
