3 0

Answer:

B

Step-by-step explanation:

circle equation is :

(x - a) ^{2}  + (y - b) ^{2}  = r^{2}

With (a) being the x coordinate of the centre and (b) being the y coordinate of the centre, r is the radius;

make sure to square the radius when using it in this formula

Evaluate the quantity 3 squared times 3 to the power of negative 5 end quantity over 5 to the power of negative two.
chubhunter [2.5K]

The value of the expression given as  [3² * 3⁻⁵]/[5⁻²] is 25/27

<h3>How to evaluate the expression?</h3>

The expression is given as:

3 squared times 3 to the power of negative 5 end quantity over 5 to the power of negative two

Rewrite properly as:

[3² * 3⁻⁵]/[5⁻²]

Apply the negative exponent law of indices

So, we have

[3² * 3⁻⁵]/[5⁻²] = [5²]/[3⁻² * 3⁵]

Apply the exponent law of indices

[3² * 3⁻⁵]/[5⁻²] = [5²]/[3³]

This gives

[3² * 3⁻⁵]/[5⁻²] = 25/27

Hence, the value of the expression given as  [3² * 3⁻⁵]/[5⁻²] is 25/27

Ket [755]

(A). A working spouse could affect all three variables. (C).People might be very satisfied with their career as long as the income is high.

(E). One-way commute times may be long because affordable housing is distant from the job.

Step-by-step explanation:

a. People may have a career following their passion, but have a low income or a long commute.

sometimes people can get jobs based on their passion but might still have low income and a long commute.

b. A working spouse could affect all three variables.

Yea a working spouse considers the income rate, job satisfaction and commute time involved in a job because it can affect their daily lives.

c. People might be very satisfied with their career as long as the income is high.

Most people are more satisfied with their career when the income rate is high.

d. One-way commute times may be long because affordable housing is distant from the job.

Income rate affects the choice of accommodation and housing.
