Answer:

  a = 9 meters

Step-by-step explanation:

The perimeter is the sum of the side lengths:

  28 m = a + 2m + a + 8m

  18 m = 2a . . . . . . . . . . . . . . . . subtract 10m, collect terms

  9 m = a . . . . . . . . . . . . . . . divide by 2

What is the multiplicative rate of change of the function
mario62 [17]

Answer: B \frac{2}{3}


Step-by-step explanation:

From the given table

When x changes from 1 to 2 , value of y changes from 6 to 4

The multiplicative rate of change=\frac{4}{6}=\frac{2}{3}

Similarly we can check

When x changes from 2 to 3 , value of y changes from 4 to \frac{8}{3}

The multiplicative rate of change=\frac{\frac{8}{3}}{4}=\frac{2}{3}

When x changes from 3 to 4 , value of y changes from  \frac{8}{3} to  \frac{16}{9}

The multiplicative rate of change=\frac{\frac{16}{9}}{\frac{8}{3}}=\frac{2}{3}

Therefore, the multiplicative rate of exponential function = \frac{2}{3}

Question 3<br> Find the equation of the line joining (-2,4) and (3,7)
otez555 [7]

Answer:

y = (3/5)x+26/5 or 5y = 3x+26

Step-by-step explanation:

Applying,

The equation of a line in two point form

(y₂-y₁)/(x₂-x₁) = (y-y₁)/(x-x₁)............... Equation 1

From the question,

Given: y₂ = 7, y₁ = 4, x₂ = 3, x₁ = -2

Substitute these values into equation 1

(7-4)/[3-(-2)] = (y-4)/(x+2)

3/5 = (y-4)/(x+2)

5(y-4) = 3(x+2)

5y-20 = 3x+6

5y = 3x+6+20

5y = 3x+26

y = (3/5)x+26/5

Hence the equation of the line is y = (3/5)x+26/5 or 5y = 3x+26
