Answer:
[tex] T = \frac{1}{f}[/tex]
And replacing we got:
[tex] T = \frac{1}{34.5 Hz}= 0.0290 s[/tex]
And then we can conclude that with the conditions given the period of the string would be 0.0290 s
Step-by-step explanation:
For this case we know the frequency associated to the 4 harmonic.
We know that by definition the frequency is the inverse of the period:
[tex] f= \frac{1}{T}[/tex]
If we solve for the period we got:
[tex] T = \frac{1}{f}[/tex]
And replacing we got:
[tex] T = \frac{1}{34.5 Hz}= 0.0290 s[/tex]
And then we can conclude that with the conditions given the period of the string would be 0.0290 s
DVD players are going out of fashion in the modern era. If 400,000 DVD players were sold this year and sales are declining at a rate of 31% per year, how many will be sold 3 years from now?
130,000
131,404
128,000
399,876
Answer:
c
Step-by-step explanation:
Answer:
399,876
Step-by-step explanation:
So, 400,000 DVD sales with a 31% decline means in the first year following, there will be a decline of 124,000 DVDs sold. So we need to take 400,000-124,000 which equals a starting point for your two is 276,000 dvds. Then, add 123,876, which gives you 399,876.

Answer:
I know I'm 10 days late on this, but the answer is 1.5
Step-by-step explanation:
1. Add 3+7+4+2:
[tex]3+7+4+2=16[/tex]
2. Divide it by 4 because we have 4 numbers being added:
[tex]\frac{16}{4} =4[/tex]
3. Subtract 4 from all numbers:
[tex]4-3=1, 7-4=3, 4-4=0,4-2=2[/tex]
4. Add the differences:
[tex]1+3+0+2=6[/tex]
5. Divide again by 4:
[tex]\frac{6}{4} =1.5[/tex]

3|2−x|=−6
can someone answer this question for me?? THNX!!!
Answer: the answer is 4
Step-by-step explanation:
3(2−x)=−6
Step 1: Simplify both sides of the equation.
3(2−x)=−6
(3)(2)+(3)(−x)=−6(Distribute)
6+−3x=−6
−3x+6=−6
Step 2: Subtract 6 from both sides.
−3x+6−6=−6−6
−3x=−12
Step 3: Divide both sides by -3.
−3x
−3
=
−12

Show the Euler-Descartes formula holds for the Great Pyramid of Cheops
Answer:
For the great pyramid of Cheops, V + F = E + 2 gives 5 + 5 = 8 + 2 which proves Euler-Descartes formula
Step-by-step explanation:
The great pyramid of Cheops is a square based pyramid therefore we have;
V + F = E + 2
Where:
V = Vertices
F = Faces
E = Edges
Hence, we have for a square pyramid;
V = 5 vertices (One at the peak, and four at the base edges)
F = 5 faces (The four lateral or side faces and the base)
E = 8 edges ( The four lateral edges and the four base edges)
Hence;
5 + 5 = 8 + 2 which proves Euler-Descartes formula.

Pythagorean Theorem: How many yards will the players have to run?
Answer:
≈ 125.3
Step-by-step explanation:
If we're using the Pythagorean Theorem to solve this, then the formula is:
[tex]a^{2}+ b^{2} =c^{2}[/tex]
So basically, by using this formula, you're finding the length that the soccer players will run diagonally. Plug in the numbers:
[tex]110^2 + 60^2 = c^2[/tex]
12100 + 3600 = [tex]c^2[/tex]
15700 = [tex]c^2[/tex]
Take the square root:
15700 = [tex]c^2[/tex]
[tex]\sqrt{15700} = \sqrt{c^2}[/tex]
125.3 ≈ c

elijah's credit card statement showed these items: Last Balance Payments Finance Rate New Charges $152.58 $45.00 1.5% $213.40 What is Elijah's new balance? $320.98 $322.59 $323.27 $397.51
Answer:
Option A,$320.98 is correct
Step-by-step explanation:
The new balance on Elijah's credit is the sum of the last balance plus new charges minus payments made.
last balance as shown by the statement was $152.58
new charges were $213.40
payment made by Elijah was $45
new balance=$152.58+$213.40-$45=$320.98
The rationale for this is that the new charges on the card account add to previous balance owed by Elijah while the payment of $45 made reduces overall balance.
Answer:
Other answer is incorrect. Elijah's new balance would be $322.59

Answer:
11.3
Step-by-step explanation:
i used the theorem of Pythagoras
Answer:
11.3
Step-by-step explanation:
In a right angled triangle: the square of the hypotenuse is equal to
the sum of the squares of the other two sides.
[tex]8^{2} + 8^{2} = x^{2}[/tex] (x is the hypotenuse)
64 + 64 = [tex]x^{2}[/tex]
[tex]x^{2}[/tex] = 128
=> x = [tex]\sqrt{128}[/tex] = 11.3137085 = 11.3
