Exit Ticket: At noon, a tank has a water depth of 9 in. After 3 hours, the depth was 8 inches. At 6pm, the depth was 7 inches. What is the initial value for the function? help will be appreciated.

Answers

Answer:

Step-by-step explanation:

The  straight line equation is:

y = m*x  + b     Where m is the slope of the line and b the intercept with   y-axis, in our case y is the depth of the tank and x (time in lapsus of 3 hours).

The slope m  =  ( y₂ -  y₁ ) / (x₂ - x₁)

We have point  A ( 3 , 8 )  and point  B ( 6 , 7 )

m  = ( 6 - 3 ) / (7 - 8 )  m = -3

We see that  each 3 hours time-depth decreases  1 in.

Then   to find the depth at the beginning of x-axis

At  noon     12   tank was  9 inches, three hours before at 9 in the morning the depth was 10 inches and:

9  in the morning   10

6  in the morning   11

3  in the midnight   12

12 in the night         13

Then 13 is the intercept with y-axis

then the equation is:

h = - 3*x + 13

Note x is time in lapsus  of 3 hours

Step-by-step explanation:

Use basic trigonometry. In this case, use sine.

sin(45) = 18 / x

18 / sin(45) = x

x = 25.4558441227

After you solve this, you will see that 25.5 is close to that.

Laura collects nickels and dimes she has a total of 47 nickels and dimes she calculated the value of the coins and found out she has $4.05 how many nickels and dimes does laura

Answers

Answer:

Number of dimes = 34

Number of nickels = 13

Step-by-step explanation:

Total number of coins = 47

Coins are in the form of nickels and dimes.

Value of a nickel = 5 cents

Value of a dime = 10 cents

Total value of coins = $4.05 or 405 cents

To find:

Number of nickels and dimes?

Solution:

Let number of nickels = [tex]x[/tex]

Money value of nickels = 5[tex]x[/tex]

Let number of dimes = [tex]y[/tex]

Money value of dimes = 10[tex]y[/tex]

Total value of coins = [tex]5x+10y[/tex]

This value is given as equal as 405.

As per question statement, the equations can be written as:

[tex]5x+10y = 405 ..... (1)\\x+ y = 47 ...... (2)[/tex]

Multiplying equation (2) with 5 and subtracting from equation (1):

[tex]10y - 5y = 405 - 235 \\\Rightarrow 5y = 170\\\Rightarrow y = 34[/tex]

Number of dimes = 34

Number of nickels  = 47 - 34 = 13

Answers

Answer:

Step-by-step explanation:

Equation for the linear function has been given as,

y = 26 - 4x

For x = 1,

y = 26 - 4(1)

  = 26 - 4

  = 22

For x = 2,

y = 26 - 4(2)

  = 26 - 8

  = 18

For x = 3,

y = 26 - 4(3)

  = 26 - 12

  = 14

For x = 6,

y = 26 - 4(6)

  = 26 - 24

  = 2

Therefore, table for the function will be,

x               y

1              22  

2              18
