Answer:

The periodic interest rate would be 4.3 %.

Step-by-step explanation:

Given,

The annual rate = 8.6%,

Thus, the periodic rate = \frac{\text{Annual rate}}{\text{Number of periods}}

Here, the period is semiannually,

∵ number of semiannual = 2,

Thus, the number of periods = 2,

Hence, the periodic rate = \frac{8.6\%}{2}

= 4.3%

Explain how you would round 33 and 89 to estimate their sum
Shalnov [3]
If I'm understanding the question correctly, this is how I would estimate the sum.

I would round each number to the nearest tens place.

33 would be rounded down to 30.

89 would be rounded up to 90.

Then I would do 90+30.

A line has a slope of -5 and passes through the point (2, 2). An equation for this line is
nalin [4]

Answer:

The equation of the  line has a slope of -5 and passes through the point (2, 2) is  y = -5x + 12 .

Option (D) is correct.

Step-by-step explanation

The equation of the line

y = mx + c

where m is the slope and c is the y - intercept .

As given

A line has a slope of -5 and passes through the point (2, 2).

The slope of the line is -5.

m = -5

Put in the equation of the line

y = -5x + c

Put x = 2 and y = 2

2 = -5 × 2  + c

2 = - 10  + c

2 + 10 = c

12 = c

Put the value of c in the y = -5x + c

y = -5x + 12

Therefore the equation of the  line has a slope of -5 and passes through the point (2, 2) is  y = -5x + 12 .

Option (D) is correct.
