Answer:

(x - 5)² + (y + 3)² = 16

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

here (h, k) = (5, - 3) and r = 4, thus

(x - 5)² + (y - (- 3))² = 4², that is

(x - 5)² + (y + 3)² = 16 ← equation of circle

Question 3, help please!

The answer is not defined.

Explanation:

The given matrix is $\left[\begin{array}{cc}{2} & {4} \\ {1} & {-6}\end{array}\right]+\left[\begin{array}{c}{1} \\ {0}\end{array}\right]$

The matrix $\left[\begin{array}{cc}{2} & {4} \\ {1} & {-6}\end{array}\right]$ has dimensions $2\times 2$

This means that the matrix has 2 rows and 2 columns.

Also, the matrix $\left[\begin{array}{l}{1} \\ {0}\end{array}\right]$ has dimensions $2\times1$

This means that the matrix has 2 rows and 1 column.

Since, the matrices can be added only if they have the same dimensions.

In other words, to add the matrices, the two matrices must have the same number of rows and same number of columns.

Since, the dimensions of the two matrices are not equal, the addition of these two matrices is not possible.

Hence, the addition of these two matrices is not defined.

1. Gross pay= monthly salary+commission

Commission = 9652*0.03 = 289.56

Gross pay = 2985+289.50 = $3274.56

2. The FICA withholding amount for the employee is 7.65% of gross income wherein 6.2% is for Social Security and 1.45% is for Medicare.

So, FICA tax = $\frac{7.65}{100}*2190= 167.535$

3. Total earnings of Carol = 642.20+115.34+62.75 = $820.29

So, her hourly wage = $\frac{820.29}{37} =22.17$

Hence, Carol's hourly wage is = $22.17
