It is estimated that the population of the world is increasing at an average rate of 1.09%. The population was about 7,632,819,325 in the year 2018. Use the equation in question 1A to predict the population of the world in 2030 (round to the nearest whole number).

the population of the world in 2030 is 8693273454

Step-by-step explanation:

We would apply the formula for exponential growth which is expressed as

y = b(1 + r)^t

Where

y represents the population, t years after 2018.

t represents the number of years.

b represents the initial population.

r represents rate of growth.

From the information given,

b = 7,632,819,325

r = 1.09% = 1.09/100 = 0.0109

Therefore, the equation that can be used to predict the population of the world after 2018 is

y = 7632819325(1 + 0.0109)^t

y = 7632819325(1.0109)^t

In 2030, t = 2030 - 2018 = 12 years

y = 7632819325(1.0109)^12

y = 8693273454

24

step-by-step explanation:

i assuming that 2 sides are 6 the other 2 sides are 4 cm so 6 times 4 is 24 : )

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47
