Answer:

Third turn point = 21 points

Step-by-step explanation:

Given:

First turn point = 12

Second turn point = 15

Find;

Third turn point

Computation:

First turn point = 12

Assume;

Point for outer circle = a

Point for inner circle = b

So,

3a = 12

Point for outer circle = 4 point

Second turn point = 15

So,

2a + b = 15

2(4) + b = 15

Point for inner circle = 7

Third turn point = 3 x 7

Third turn point = 21 points

Farmer Jack needs 1,800 square feet of garden space to have enough corn for a year. His garden space is currently 10 5?6 feet by
sergey [27]

Answer:

1,605\ ft^{2}

Step-by-step explanation:

step 1

Find the area of the garden space

First convert mixed number to an improper fraction

10\frac{5}{6}\ ft=\frac{10*6+5}{6}=\frac{65}{6}\ ft

A=\frac{65}{6}*18=195\ ft^{2}

step 2

Find how much more land Farmer Jack needs to plant the rest of his corn

1,800\ ft^{2}-195\ ft^{2}=1,605\ ft^{2}

Rate of change of rational functions
densk [106]

Answer:

0.635

Step-by-step explanation:

rate~of~change = \dfrac{f(x_2) - f(x1)}{x_2 - x_1}

rate~of~change = \dfrac{f(x_2) - f(x1)}{x_2 - x_1}

x_1 = 0       x_2 = 0.3

f(x) = \dfrac{-7x^3}{x^4 - 1}

f(x_1) = f(0) = \dfrac{-7(0)^3}{(0)^4 - 1}

f(x_1) = \dfrac{0}{-1} = 0

f(x_2) = f(0.3) = \dfrac{-7(0.3)^3}{(0.3)^4 - 1}

f(x_2) = \dfrac{-0.189}{-0.9919} = 0.190543

rate~of~change = \dfrac{0.190543 - 0}{0.3 - 0} = 0.635
