Mary has been offered two jobs.Job a has a starting salary of 36,000 and a raise of 1500 every year.Job B has a starting salary

zhannawk [14.2K]

Answer:

Number of year Mary’s salary be the same at both = 7 year

Equal salary amount = 46,500

Step-by-step explanation:

Given:

Starting salary in job A = 36,000

Gain per year in job A = 1,500

Starting salary in job B = 29,000

Gain per year in job B = 2,500

Find:

Number of year Mary’s salary be the same at both = ?

Equal salary amount = ?

Computation:

Assume : in x year salary from job A is equal to salary from job B

Salary from job A in x year = 36,000 + 1,500 x .........Eq1

Salary from job B in x year = 29,000 + 2,500 x .........Eq2

From Eq1 and Eq2

36,000 + 1,500 x = 29,000 + 2,500 x

7,000 = 1,000 x

x = 7 Year

Number of year Mary’s salary be the same at both = 7 year

From Eq1....

Equal salary amount = 36,000 + 1,500(7)

Equal salary amount = 36,000 + 10,500

Equal salary amount = 46,500

An ellipse has a center at the origin, a vertex along the major axis at (0, 17), and a focus at (0, −8).

MAVERICK [17]

Answer:

The last one.

Step-by-step explanation:

The standard form equation of an ellipse with foci on the y-axis is ...

y²/a² +x²/b² = 1

where "a" and "b" are the lengths of the semi-major and semi-minor axes, respectively. If "c" is the distance from the center to the focus, then this relation also holds:

b² +c² = a²

For this ellipse ...

b² + 8² = 17²

289 -64 = b² = 225 . . . . . subtract 8²

b = 15 . . . . . . . . . . . . . . . . . take the square root

The equation of the ellipse is then ...

y²/17² +x²/15² = 1
