Answer:
86 million
Step-by-step explanation:
Where F is future population, P is present population and n is period in years, R is rate of growth in percentage
Taking period between 1993 to 1996 as 3 years, we can get the rate of population growth rate
Getting cube root of both RHS and LHS
1+R/100=1.018185791
R/100=0.018185791
R=1.818579071%
Between 1993 and 2003 is 10 years hence n=10
F= 86 million
The answer is option B - 10 strips
Explanation:
Given is :
The total length of fabric given is = 5 yards
Maria divides this fabric in yards strips each.
So, total number of strips made are =
In yards, strips made = 1
In 1 yard, strips made = 2
In 5 yards, strips made are =
Hence, total strips are 10.
the distance from the origin is 5, so
sqrt(x²+y²)=5
x²+y²=25
substitue y=x²
y+y²=25
y²+y-25=0
solve using calculator or the formula
to get
y =( -1+sqrt(1+4*25))/2
or y = (-1-sqrt(1+4*25))/2
the second solution is rejected because a square cannot be negative
the value of x is the positive or negative (sqrt... or -sqrt...) or y
It's going to be going up. That means the answer is b.
Hope this helped☺☺
