A musical instrument has a pitch of 220 hertz when the wavelength is 3 feet. When the wavelength is 4 feet, the pitch is 165 her

earnstyle [38]

We know that
Inverse Variation is a relationship between two variables in which the product is a constant
so
let
x------> a pitch of a musical instrument
y------> the wavelength
x*y=k

find the value of k

for x=220 hertz y=3 ft
x*y=k
220*3=k
k=660

for x=165 hertz y=4 ft
x*y=k
165*4=660
k=660

the answer part a) is
the type of variation between pitch and wavelength is an inverse variation

part b) What is the pitch when the wavelength is 5 feet?
x=?
y=5 ft
k=660
x*y=k------> solve for x
x=k/y----------> x=660/5-----> x=132 hertz

the answer Part b) is
132 hertz

Each day her goal is to make 4 more baskets than she made thr day before. If she makes 10 baskets the first day and meets her go

irina [24]

Answer:

Janelle will make 62 baskets on 14th day.

Step-by-step explanation:

Given,

Number of goals on 1st day = 10

We need to find the number of goals on 14th day.

Solution,

Since Janelle made 10 goals on 1st day and want to make 4 more basket from the day before.

So we can say that;

$a_1=10$ and $d=4$

And also $n=14$

here $a_1$ = first term

d = common difference

n = number of terms

Now we apply the formula of A.P.

$T_n=a_1+(n-1)d$

now substituting the given values, we get;

$T_{14}=10+(14-1)4\\\\T_{14}=10+13\times 4\\\\T_{14}=10+52 =62$

Hence Janelle will make 62 basket on 14th day.

One of the problems with our current election system is??

12345 [234]

Answer:

Assuming you mean the US election a problem with our electron is the person who wins the most popular vote doesn't always win.

Why is this a problem?

We vote for who we want as a president as it should work, but then the most elected doesn't always become president. Almost like our votes do not matter and is very discouraging.

Hope this helps!
