Illusion [34]

Answer:

Given the following exponential function, identify whether the change represents growth or decay, and determine the percentage r
GREYUIT [131]

Answer:

  • Decay
  • Decrease rate is 8%

Step-by-step explanation:

<u>Given function:</u>

  • y = 490(0.92)^x

The base of the exponent is 0.92. This represents a decay as 0.92 is less than 1. It would be a growth function is the base was greater than 1.

<u>The rate of decrease is </u>

  • 0.92 times

<u>Percent decrease is </u>

  • (1 - 0.92)*100% = 8%

klasskru [66]

Answer: 85/12 fewer bushels per acre

Step-by-step explanation:

Hi, to answer this question we have to write an expression with the information given and solve it:

We simply have to divide the total loss (21 1/4) by the number of acres (3):

Mathematically speaking:

21 1/4 ÷3 = (21(4) +1)/4 ÷3 = 85/4 ÷ 3= 85/12 fewer bushels per acre

Need help with these two questions linear relations.
wel

Answer:

b. y = -7x + 4

   1.    y = -7(-5)+ 4 = 35+4= 39

   2. -24= -7x + 4

    -28 = -7x

       4 = x

    3. y = -7(0)+4= 4

    4. 0 = -7x+4

        -4= -7x

         4/7 = x

c. 3y - 5x = 15

 1. 3y - 5(6)

    3y-30=15

    3y=45

      y = 15

   2. 3(-10)-5x=15

        -30-5x=15

         -5x = 45

            x = -9

    3. 3y-5(0)=15

        3y=15

         y=5

    4. 3(0)-5x=15

         0-5x=15

          -5x=15

           x=-3
