Answer:

12) Line segment AB

m_{AB} = \frac{7-4}{10-4}= \frac{1}{2}

13) Line segment CD

m_{CD} = \frac{6-11}{15-13}=-\frac{5}{2}

14) Line segment EF

m_{EF} = \frac{7-11}{4-3}= -4

15) Line segment GH

m_{GH} = \frac{5-2}{8-6}= \frac{3}{2}

16) Line segment IJ

m_{IJ} = \frac{0-(-6)}{0-4}=-\frac{3}{2}

17) Line segment KL

m_{KL} = \frac{-2-(-3)}{5-(-2)} = \frac{1}{7}

18) Line segment MN

m_{MN} = \frac{5-5}{3-(-4)} = 0

19) Line segment OP

m_{OP} = \frac{4-(-2)}{13-13} = \frac{1}{0}

20) Line segment QR

m_{QR} = \frac{7-11}{-2-(-7)} = -\frac{4}{5}

21) Line segment ST

m_{ST} = \frac{-2-(-3)}{10-9} = 1

Step-by-step explanation:

Coordinates are now described: A(x,y) = (4,4), B(x,y) = (10, 7), I(x,y) = (-6, 4), J(x,y) = (0,0), Q(x,y) = (-7,11), R(x,y) = (-2,7), C(x,y) = (13,11), D(x,y) = (15, 6), K(x,y) = (-2, -3), L(x,y) = (5,-2), S(x,y) = (9,-3), T(x,y) = (10, -2), E(x,y) = (3, 11), F(x,y) = (4,7), M(x,y) = (-4,5), N(x,y) = (3, 5), G(x,y) = (6,2), H(x,y) = (8,5), O(x,y) = (13,-2), P(x,y) = (13,4)

The slope of each line segment is calculated by applying definition of secant line:

12) Line segment AB

m_{AB} = \frac{7-4}{10-4}= \frac{1}{2}

13) Line segment CD

m_{CD} = \frac{6-11}{15-13}=-\frac{5}{2}

14) Line segment EF

m_{EF} = \frac{7-11}{4-3}= -4

15) Line segment GH

m_{GH} = \frac{5-2}{8-6}= \frac{3}{2}

16) Line segment IJ

m_{IJ} = \frac{0-(-6)}{0-4}=-\frac{3}{2}

17) Line segment KL

m_{KL} = \frac{-2-(-3)}{5-(-2)} = \frac{1}{7}

18) Line segment MN

m_{MN} = \frac{5-5}{3-(-4)} = 0

19) Line segment OP

m_{OP} = \frac{4-(-2)}{13-13} = \frac{1}{0}

20) Line segment QR

m_{QR} = \frac{7-11}{-2-(-7)} = -\frac{4}{5}

21) Line segment ST

m_{ST} = \frac{-2-(-3)}{10-9} = 1

Which point is not on the graph of the equation y=10+x
SCORPION-xisa [38]

Answer:

C

Step-by-step explanation:

Check all points:

A: x=0, y=10, then from the equality 10=10+0 follows that A lies on the line.

B: x=3, y=13, then from the equality 13=10+3 follows that B lies on the line.

C: x=8, y=2, then from the inequality 2=10+8 follows that C doesn't lie on the line.

D: x=5, y=15, then from the equality 15=10+5 follows that D lies on the line.

A town has 5000 people in year t = 0. Calculate how long it takes for the population P to double once, twice, and three times, a
UNO [17]

Answer:

Step-by-step explanation:

At the time t = 0, population of the town = 5000

Rate of population increase = 500 per year

Therefore, the equation that will represent the population will be

P_{t}=P_{0}+500t

Where P_{t} = Population after t years

P_{0}= Initial population

t = Time in years

a). For double once the population will be 500×2 = 10000

By plugging in the values in the equation,

10000 = 5000 + 500t

500t = 10000 - 5000

500t = 5000

t = \frac{5000}{500}

t = 10 years

For Double twice,

Population will be = 10000×2 = 20000

Now we plug in the values in the equation again

20000 = 5000 + 500t

500t = 20000 - 5000

500t = 15000

t = \frac{15000}{500}

t = 30 years

For double thrice,

Population of the town = 20000×2 = 40000

Now we plug in the values in the equation,

40000 = 5000 + 500t

500t = 40000 - 5000

500t = 35000

t = \frac{35000}{500}

t = 70 years

b). If the population growth is 5%.

Then the growth will be exponential represented by

T_{n}=T_{0}(1+\frac{r}{100})^{t}

T_{n} = Population after t years

T_{0} = Initial population

t = time in years

For double once,

Population after t years = 10000

10000=5000(1+\frac{5}{100})^{t}

(1.05)^{t}=\frac{10000}{5000}

(1.05)^{t}=2

Take log on both the sides

log(1.05)^{t}=log2

tlog(1.05) = log2

t = \frac{log2}{log1.05}

t = 14.20 years

For double twice,

Population after t years = 20000

20000=5000(1+\frac{5}{100})^{t}

(1.05)^{t}=\frac{20000}{5000}

(1.05)^{t}=4

Take log on both the sides

log(1.05)^{t}=log4

tlog(1.05) = log4

t = \frac{log4}{log1.05}

t = 28.413 years

For double thrice

Population after t years = 40000

40000=5000(1+\frac{5}{100})^{t}

(1.05)^{t}=\frac{40000}{5000}

(1.05)^{t}=8

Take log on both the sides

log(1.05)^{t}=log8

tlog(1.05) = log8

t = \frac{log8}{log1.05}

t = 42.620 years
