Answer:

4 lbs per day

Step-by-step explanation:

Take the final weight and subtract the starting weight

65-5 = 60

Divide by the number of days

60/15 = 4

The average rate of change is 4 lbs per day

Christian just lit a new candle and then let it burn all the way down to nothing. The length of the candle remaining unburned, i

AVprozaik [17]

Given:

The length of the candle remaining unburned, in inches, can be modeled by the equation

$L=6-t$

where, t represents the number of hours since the candle was lit.

To find:

The slope and its interpretation in the context of the problem.

Solution:

Slope intercept form of a linear function is

$y=mx+b$

where, m is slope and b is y-intercept or initial value.

We have,

$L=6-t$

It can be written as

$L=6+(-1)t$

The coefficient of t is -1. So, using slope intercept form the slope of this equation is -1.

Here, -1 means length of the candle remaining unburned is decreasing at the rate of 1 inch per hour.

The check-cashing store also makes one-month add-on interest loans at 7.8 percent discount interest per week. Thus if you borrow

masya89 [10]

Answer:

APR = 416%

EAR = 5370.60%

Step-by-step explanation:

Given:

Interest rate = 7.8% per week

Now,

In an year there are total 52 weeks

thus,

The APR (Annual percentage rate) = Interest rate × Total weeks in an year

APR = 8% × 52

APR = 416%

and, EAR ( Effective Annual Rate ) = ( 1 + r )ⁿ - 1

Here,

r is the interest rate per week

n is the total weeks in an year

thus,

EAR ( Effective Annual Rate ) = ( 1 + 8% )⁵² - 1

= ( 1 + 0.08 )⁵² - 1

= 53.7060

53.7060 × 100% = 5370.60%

Which complex number has a distance of V17 from the origin on the complex plane?

Nataly_w [17]

Answer:

$4-i$

Step-by-step explanation:

Use the formula for the distance of a complex number from the origin on the complex plane.

$\sqrt{a^2+b^2}$

$a+bi$

$4-i$

$\sqrt{4^2-i^2}$

$\sqrt{4^2+(-1)^2}=\sqrt{16+1}=\sqrt{17}$

The complex number that has a distance of $\sqrt{17}$ is $4-i$ .
