Select the correct answer. A sound wave enters a new medium where sound travels faster. How does this affect the frequency and wavelength of the sound? A. The frequency increases and the wavelength decreases. B. The frequency decreases and the wavelength increases. C. The frequency stays the same and the wavelength increases. D. The frequency stays the same and the wavelength decreases. E. Neither the frequency nor the wavelength is affected.

Answers

Answer:

The correct answer is E. Neither the frequency nor the wavelength is affected. Explanation: The wave frequency does not affect the speed of that wave. An increase in frequency of a wave causes a decrease in wavelength while the wave speed remains the constant. The speed of the waves is significantly higher at higher tensions.

The graph models the value of an automobile over a 7 year period of time.
Which equation best represents the relationship between x, the age of the automobile in years, and y, the value of the automobile in dollars​

Answers

Answer:

y=-500x+22,000

Step-by-step explanation:

It's this one because the 22,000 shows the initial value of the automobile and -500x is how much value the automobile loses per year.

Y = mx + c

C = 22,000

But slope is unknown

Y= mx + 22000

Step-by-step explanation:

evaluate -6(7/6)+2(1/3)=

Answers

-6.333333... OR -19/3

In the problem: -6(7/6) + 2(1/3) Let's only worry about the left of the equal sign for now.

-6(7/6) we have to simplify this. So what we do is we multiply -6(7) and leave the denominator the same so -6(7/6) is -7.

Now we simplify the right part of this problem.

2(1/3) just like the 1st time, we have to simplify this. So what we do is we multiply 2 and 1 together and leave the denominator the same. So, 2(1) is 2 and leave the denominator the same so the answer is 2/3

Now add them together.

-7 + 2/3 = 6.333...

A company paid $ 391 for 15 bushes and 8 bonsai trees . They had to purchase 9 more bushes and 5 more bonsai trees for $ 241 . What is the cost of each bush and bonsai tree ? the boxes below .

Answers

Answer:

Cost of one bush = x = $9

Cost of one bonsai tree = y = $32

Step-by-step explanation:

Let Cost of one bush = x

Cost of one bonsai tree = y

From the expression: A company paid $ 391 for 15 bushes and 8 bonsai trees

We made equation: [tex]15x+8y=391[/tex]

and From the expression: They had to purchase 9 more bushes and 5 more bonsai trees for $ 241 , we made equation: [tex]9x+5y=241[/tex]

Solving both equations simultaneously we can find value of x and y

Let:

[tex]15x+8y=391--eq(1)\\9x+5y=241--eq(2)[/tex]

We will use elimination method to solve these equations.

Multiply eq(1) by 5 and eq(2) by 8 and subtract

[tex]75x+49y=1955\\72x+40y=1928\\- \ \ \ - \ \ \ \ \ \ \ -\\--------\\3x=27\\x=\frac{27}{3}\\x=9[/tex]

So, value of x=9

Now finding value of y by putting value of x in equation 1

[tex]15x+8y=391\\Put \ x=9\\15(9)+8y=391\\135+8y=391\\8y=391-135\\8y=256\\y=\frac{256}{8}\\y=32[/tex]

So, value of y=32

Cost of one bush = x = $9

Cost of one bonsai tree = y = $32
