If each edge of a square increased by 50%, by what percentage does the a?rea increase

1 answer:

8 0

Area of any rectangle = L W. Increase them 50% and they become 1.5L and 1.5W. New area is (1.5L)(1.5W) = (1.5 squared)(L W) = 2.25 (original area).

Answer:

49145 years

Step-by-step explanation:

In a certain country the life expectancy for women in 1990 was 45 and in 2000 it was 85?years.

Assuming that life expectancy between 2000 and 2100 increases by the same percentage as it did between 1900 and 2000,what will life expectancy be for women in 2100?

In 10 years, the expectancy increased by 85/45 = 17/9

between 2000 and 2100, it will increas by 10 time 10 years, so expected expectancy is $85*(\frac{85}{45})^{10} = 49145$ years

Use the graph of a translated function below to answer this question

Talja [164]

The graph of the function $y=x^3$ has the point of inflection at the origin. From the diagram you can the that the graph $y=f(x - h) + k$ has the point of inflection at point (-2,-3). So you should translate the graph of the function $y=x^3$ 2 units to the left and 3 units down. This translation is acting on function $y=f(x)$ in the following way:
