Question 11

Mathematics
1 answer:
True [87]3 years ago
8 0

Answer:

about $2546.88

Step-by-step explanation:

You would multiply 15x20 to find the area, which is 300 sq ft. Then, you would find the cost per square foot by dividing 2275/300 which is 7.58 rounded to the nearest hundredth. Now that you have the cost per square foot, you find the area of 12x28 which is 336. Then, you just multiply 336(7.58) which is equal to $2546.88

Use the fact that the world population was 2,560 million in 1950 and 3,040 million in 1960 to model the population of the world
Serga [27]

Answer:

The relative growth rate is 18.75%.

Step-by-step explanation:

If the world population was 2.560 million in 1950 and 3.040 million in 1960, it means that there was a growth of 480 million people in 10 years. Thus, it is a growth of 18.75%, according to the following calculation:

2,560 = 100

480 = X

(480 x 100) / 2,560 = X

48,000 / 2,560 = X

18.75 = X

Therefore, if this growth rate were to be maintained, in subsequent years the world population would evolve as follows:

1970: 3,040 x 1.1875 = 3,610 million inhabitants

1980: 3,610 x 1.1875 = 4,286 million inhabitants

1990: 4,286.8 x 1.1875 = 5,090 million inhabitants

In Lesson 3.05 we discussed comparing the key features of two functions given in different forms. Given the functions below:
vladimir1956 [14]

Answer:


Step-by-step explanation:

a) Compare the y-intercepts of f(x) and g(x). Use complete sentences.

The  functions f(x) and g(x) are different, the y-intercepts  for each function is y-intercepts (0,-1/3) for f(x)= 1/x-3 and y-intercepts  (0,0) for g(x) as shown on the graph.



b) Compare the vertical asymptotes of f(x) and g(x). Use complete sentences.

The  functions f(x) and g(x) have different Vertical Asymptotes, f(x)= 1/x-3 Vertical Asymptotes is x = 3 while g(x) as shown on the graph Vertical Asymptotes is   x = 4. Both functions do have Horizontal Asymptotes that are the same y = 0

\begin{cases} x=-5\implies &x+5=0\\ x=3\implies &x-3=0 \end{cases}\qquad \implies \underline{a(x+5)(x-3)~~ = ~~\stackrel{0}{y}} \\\\\\ \stackrel{\textit{we also know that}}{P(0)=-30}\implies \begin{cases} x=0\\ y=-30 \end{cases}\implies a(0+5)(0-3)~~ = ~~-30 \\\\\\ a(5)(-3)=-30\implies -15a=-30\implies a=\cfrac{-30}{-15}\implies \boxed{a=2} \\\\[-0.35em] ~\dotfill\\\\ 2(x+5)(x-3)=y\implies 2(\stackrel{F~O~I~L}{x^2+2x-15})=y\implies \underline{2x^2+4x-30=y}
