What are the solutions to the equation and check for extraneous solutions: 16=(x-2)^2/3

GuDViN [60]

Answer:

we have x = -62 or x = 66

Step-by-step explanation:

16=(x-2)^2/3

I would take square root first

4 = (x - 2)^ (1/3)

or -4 = (x - 2)^(1/3)

.....

4^3 = x - 2

64 = x - 2

x = 66

or -4 ^3 = x - 2

-64 = x - 2

x = -62

we have x = -62 or x = 66

Mr. I does a job in x hours while Mr. L can do it in y hours. How much of the job could they do together if they were to work fo

dimulka [17.4K]

Answer: Work done by both of them in k hours is

$\frac{k(x+y)}{xy}$

Explanation:

Since we have given that

Number of hours Mr. I does a job = x hours

Number of hours Mr. L does a job = y hours

Work done by Mr. I is given by

$\frac{1}{x}$

Work done by Mr. L is given by

$\frac{1}{y}$

Work done if they do together is given by

$\frac{1}{x}+\frac{1}{y}\\\\=\frac{x+y}{xy}$

Work done if they work together for k hours is given by

$\frac{x+y}{xy}\times k\\\\=\frac{k(x+y)}{xy}$

Hence, work done by both of them in k hours is

$\frac{k(x+y)}{xy}$

The ground temperature at an airport is 16 °C. The temperature decreases by 5.6 °C for every increase of 1 kilometer above the g

love history [14]

0 km = 16

1km = 16 - 5,6 = 10,4

2km = 10,4 - 5,6 = 4,8

3km = 4,8 - 5,6 = -0,8

4km = -0,8 - 5,6 = -6,4

5km = -6,4 - 5,6 = -12
