I'm afraid your equation is not correctly set up. You need to identify the longest side of this right triangle; it is x. This is the "hypotenuse." Next, identify the lengths of the legs: they are sqrt(13) and 2sqrt(2).
Here's a refresher on the Pythagorean Theorem:
(hypotenuse)^2 = (leg 1)^2 + (leg 2)^2
Applying this Theorem here, [x]^2 = [2sqrt(2)]^2 + [sqrt(13)\^2
Solve this for x^2, and then take the positive root (only) of your result.
Answer:
about 409.946 Hz
Step-by-step explanation:
The multiplier of frequency is (√(tension multiplier))/(length multiplier), so is ...
(√1.25)/1.2 = (5/12)√5 ≈ 0.931695
So, the longer, tighter string will have the lower frequency of about ...
0.931695×440 Hz ≈ 409.946 Hz
Answer:
9y+3
Step-by-step explanation:
you add all the common numbers and you end up with:
9y^6+3+y^-5
then you put the y^-5 under the other numbers and make it positive so it becomes:
9y^6+3/y^5, then you subtract the exponents of y: 6-5, so that cancels out the y on the bottom making it:
9y+3
Answer:
Total number of tables of first type = 23.
Total number of tables of second type = 7
Step-by-step explanation:
It is given that there are 30 tables in total and there are two types of tables.
Let's call the two seat tables, the first type as x and the second type as y.
∴ x + y = 30 ......(1)
Also a total number of 81 people are seated. Therefore, 2x number of people would be seated on the the first type and 5y on the second type. Hence the equation becomes:
2x + 5y = 81 .....(2)
To solve (1) & (2) Multiply (1) by 2 and subtract, we get:
y = 7
Substituting y = 7 in (1), we get x = 23.
∴ The number of tables of first kind = 23
The number of tables of second kind = 7
