Answer:
A.
The y-intercept of m is less than the y-intercept of n.
Step-by-step explanation:
y-intercept of a function:
The y-intercept of a function is the value of y when
Function n represents a cubic function that passes through the points (-1,0) and (0,2).
When , and thus, the y-intercept is y = 2.
Function m:
When , and thus, the y-intercept is y = -6, which is a smaller number than 2, so the y-intercept of m is less than the y-intercept of n, and the correct answer is given by option A.
Since the population of Guatemala follows an exponential
growth, therefore the equation describing the population over time should be in
the form:
p = p0 (1 + r)^t
where,
p = is the population at specified time t
p0 = is the initial population (measured starting year
2000) = 12.7 m
r = the growth rate
t = time in years
A. Calculating for the growth rate r when p = 30 and t =
20:
30 = 12.7 (1 + r)^20
1 + r = (30 / 12.7)^(1/20)
r = (30 / 12.7)^(1/20) – 1
r = 0.0440
So the equation is:
p = p0 (1.0440)^t
B. Calculating for the growth rate r when p = 30 and t =
125:
30 = 12.7 (1 + r)^125
1 + r = (30 / 12.7)^(1/125)
r = (30 / 12.7)^(1/125) – 1
r = 0.0069
So the equation is:
p = p0 (1.0069)^t
Answer:40,503
14,256 was the money that got taken away and 26,247 is how much she had left so in total if you add you’ll get 40,503.
The formula:
A = bh + L (s1 + s2 + s3)
A: area
b: base
h: height
L: length
s1: side 1 (cross-sectional area)
s2: side 2 (cross-sectional area)
s3: side 3 (cross-sectional area)
Here’s an example (see attached image)
A = (4 x 6) + (12 x [7 + 7 + 4])
A = (24) + (12 x 18)
A = 24 + 216
A = 240cm^2
