The answer is 10x
Step-by-step explanation:
Answer:
20. 300π m³
21. 457 1/3 π cm³
Step-by-step explanation:
20. r = 10 ÷ 2 = 5
V = 5² × 12 × π = 25 × 12π=300π m³
21. r = 14 ÷ 2 = 7
V = \frac{4}{3} \pi 7x^{3}
V = 457 1/3 π cm³
Answer:
18.84 ft
Step-by-step explanation:
2*3.14*3=18.84 ft
Answer:
(x+6)^2 + y^2 = 1 then isolate y^2 by subtracting (x +6)^2 from both sides, we get
y^2 = 1 - (x + 6)^2
expanding the right side, we now have
y^2 = 1-(x^2 + 12x +36)
y^2 = 1-x^2-12x -36
y^2 = -x^2 -12x - 35 therefore the solution is choice A
Step-by-step explanation:
Answer: Approximately 6573481.358 Hispanic businesses
Step-by-step explanation:
In 2009, the number of Hispanic owned businesses was 1.15 million
In 2013, the number of Hispanic owned businesses was 1.52 million
Since the growth is exponential, we would apply
Tt = ar^t-1
Where Tt is the number of Hispanic owned businesses after t years
a is the number of Hispanic owned businesses in 2009
r is the common ratio or exponential growth rate of the number of Hispanic owned business
at 2013 , t = 5(t= 0 in 2009 to t= 5 in 2013)
1520000 = 1150000 × r^5-1
1520000 / 1150000 = r^4
152/115 = r^4
1.32174 = r^4
Taking 4th root of both sides,
r = 1.07222
We want to determine the number of Hispanic owned business that would be there in 2034. It becomes
T2034 = 1150000 × 1.07222^25
T2034 = 1150000 × 5.7160
T2034 = 6573481.3579901
Approximately 6573481.358 Hispanic businesses
