What is the annual compound interest rate for an investment account modeled by the function y=12⋅1.18t ?
NikAS [45]

Answer:

The interest rate for the given investment is 18%.

Step-by-step explanation:

We are given that,

The function representing the investment model is, y=12(1.18)^t.

It is required to find the interest rate for the investment.

Since, the function can be re-written as,

y=12(1.18)^t

i.e. y=12(1+0.18)^t

So, on comparing with the formula for compound interest i.e. A=P(1+r)^t, where 'r' is the interest rate.

We have that,

The interest rate for the given investment is 0.18 i.e. 18%.

Find the coordinates of the midpoint M of the segment with the given endpoints. Then find the distance between the two points. R
Mrac [35]

Answer:

Midpoint (-2,4)

distance nearest tenth = 8.9

The approximate distance = 9

Step-by-step explanation:

Formulas

PQ midpoint = (x2 + x1)/2, (y2 + y1)/2

distance d = sqrt( (x2 - x1)^2 + (y2 - y1)^2 )

Givens

x2 = -4

x1 = 0

y2 = 1

y1 = 7

Solution

M(PQ) = (-4+0)/2, (1 + 7)/2

M(PQ) = -2, 4

The midpoint is -2,4

The distance = sqrt( (4 - 0)^2 + (1 + 7)^2 )

The distance = sqrt(16 + 64)

The distance = sqrt(80)

The distance = 4√5           exactly

The distance = 8.94    

The distance = 8.9            To the nearest tenth

Question 2

The distance is rounded to the nearest whole number which is 9.

Most people can walk about 3750 feet in 15 minutes what is the unit rate in feet per minute for this walking pace
Debora [2.8K]

Based on the calculations, the unit rate in feet per minute for this walking pace is equal to 250 feet per minute.

<h3>How to calculate the unit rate?</h3>

A unit rate refers to a measurement of a quantity which is calculated as a ratio of one parameter to another.

This ultimately implies that, we would divide the distance covered in feet by the time taken to cover this distance as follows:

Unit rate = distance/time

Unit rate = 3750/15

Unit rate = 250 feet per minute.
