Answer:

Step-by-step explanation:

7.

y= -2x+2

8.

y= -x-3

9.

y= 2/3 x + 1

10.

I'd put a point on (0, 15) , (1, 30), (2, 45) and etc....

Use a ruler to connect these points and use it to draw a straight line that hits all these points.

Good luck

A school is arranging a field trip to the zoo. The school spends 635.66 dollars on passes for 34 students and 3 teachers. The sc
Nataly [62]

Answer:

Step-by-step explanation:

Let the students price = x

Let the teacher's price = y

34x + 3y = 635

34y = 299.54

y = 299.54 / 34

y = 8.81

The only way to do this is to assume that students and teachers are charged the same amount for admission. But the question should say so.

So x = y

37x = 635.66

x = 635.66 / 37

x = 17.18

So the total spent per student was

8.81 + 17.18 = 25.99

You can peel 48 potatoes in 10 minutes. How long will it take you to peel 100 potatoes?
dybincka [34]

Answer:

About 20.8 minutes

Step-by-step explanation:

TO solve this just think of it as a ratio. The number of potatoes goes on top and the time goes on bottom.

48

__

10

That is what the first one would look like. In the second one we know the number of potatoes but we are trying to find the time (x).

100

___

 x

Take these two ratios and set them equal to each other.

\frac{48}{10} =\frac{100}{x}      Next you cross multiply (take 48 times x and 100 times 10).

48x=1000    Now divide by 48 and you have your answer.

About 20.8 minutes

A spring with a spring constant k of 100 pounds per foot is loaded with 1-pound weight and brought to equilibrium. It is then st
shutvik [7]

Answer:

Equation of movement y(t)

y(t)=sin(10t-\pi/2)

Amplitude: 1 inch

Period: 0.628 seconds

Step-by-step explanation:

If there is no friction, the amplitude will be the length it was streched from the equilibrium. In this case, this value is 1 inch

A=1\,inch

The period depends on the mass and the spring constant.

The formula for the period is:

T=\frac{1}{f} =\frac{2/pi}{\omega} =2\pi\sqrt{\frac{m}{k}}=2\pi\sqrt{\frac{1}{100}}=2\pi*0.1=0.628\, s

The model y(t) for the movement of the mass-spring system is

y(t)=A\cdot sin(\omega t +\phi)\\\\A=1\\\\\omega=\sqrt{k/m} =\sqrt{100/1}=10\\\\y(0)=Asin(\phi)=-A\\\\ \phi=arcsin(-1)=-1.571=-\pi/2\\\\\\y(t)=sin(10t-\pi/2)
