If the area of the following parallelogram is 135 square feet, what is the length of the base?

a 9 ft
b 27 ft
c 675 ft
d 81 ft

Answers

Answer:

9ft

Step-by-step explanation:

The area is 135ft and the formula for area is length x width.

on the image it shows the height is 5yds and we want feet since that's that the area is in. a yard = 3 feet so its 3 x 5 = 15.

since the formula to find area is multiplication, use division to find a number in the equation. so

135 divided by 15 = 9.

The length of the base is 9ft.

Matilda has been studying exponential functions in her algebra class and has started to notice a pattern.

For some exponential functions, when she plugs in larger and larger numbers, she gets larger and larger numbers. For others, she gets smaller and smaller numbers. And for some, plugging in larger and larger numbers actually gets her closer and closer to one number.

Which of the following exponential functions get closer and closer to one value as you plug-in larger and larger values for x?

Select one:
A. f(x)=(34)^(x)+9
B. f(x)=0.45(1.9)^(x)
C. f(x)=(65)^(x)−6

the population of center city is modeled by exponential function f, where x is the number of years after the year of 2015. the graph of f is shown on the grid. which inequality best represents the range of f in this situation?

Answers

Answer:

the Answer is B) y >= to 250,000

The requried inequality that represents the range of the function shown is f(x) ≥ 250,000.

What is the range?

The range is a key concept in the study of sets and it defines as the set of values that come out to an outcome for a certain mathematical operation.

Here,
As mentioned in the question, the population of the central city is modeled by exponential function f, where x is the number of years after the year of 2015.

As the graph starts from 0 (as the year 2015) and goes to an unknown end implying over the x-axis which is its domain. Corresponding to this, the range starts from 250000 on the y-axis and goes to infinity.

Thus, the requried inequality that represents the range of the function shown is f(x) ≥ 250,000.
