Answer:

r + 3 = 2

First, subtract 3 from both sides. / Your problem should look like: r = 2 - 3

Second, simplify 2 - 3 to -1. / Your problem should look like: r = -1

Natalie has $5000 and decides to put her money in the bank in an account that has a 10% interest rate that is compounded continu

Vedmedyk [2.9K]

Answer:

Part 1) Is a exponential growth function

Part 2) $A=5,000(e)^{0.10t}$ or $A=5,000(1.1052)^{t}$

Part 3) $\$6,107.01$

Part 4) $\$13,591.41$

Step-by-step explanation:

Part 1) What type of exponential model is Natalie’s situation?

What type of exponential model is Natalie’s situation?

we know that

The formula to calculate continuously compounded interest is equal to

$A=P(e)^{rt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

e is the mathematical constant number

we have

$P=\$5,000\\r=10\%=0.10$

substitute in the formula above

$A=5,000(e)^{0.10t}$

Applying property of exponents

$A=5,000(1.1052)^{t}$

therefore

Is a exponential growth function, because the base is greater than 1

Part 2) Write the model equation for Natalie’s situation

$A=5,000(e)^{0.10t}$ or $A=5,000(1.1052)^{t}$

see Part 1)

Part 3) How much money will Natalie have after 2 years?

For t=2 years

substitute

$A=5,000(e)^{0.10*2}=\$6,107.01$

Part 4) How much money will Natalie have after 10 years?

For t=10 years

substitute

$A=5,000(e)^{0.10*10}=\$13,591.41$

A craftsman makes a circular table with a radius of 55

Rudik [331]

Answer:

Hey mate here is your answer...

Step-by-step explanation:

smaller circular table to be made

with a diameter only half as big... and diameter of big table is (2*55)= 110cm.... So half diameter of big is (110/2)= 55cm

therefore, diameter of smaller table is 55cm and radius of it's (55/2)= 27.5cm

circumference of circle = 2πr

= 2*3.14*27.5

= 172.7 cm = 27.5cm

hope it helps you ❣️

Which equation shows the point-slope form of the line that passes through (-9, -3) and has a slope of -6?

Snowcat [4.5K]

Answer:

y=-6x-57 is your answer.

Step-by-step explanation:

You will use this equation:

y-y1=m(x-x1). The y1 is -2 and the x1 is -9.

y-(-3)=-6(x-(-9)). You will the distribute the -6 into the x and the -9.

y+3=-6x-54. You will then subtract 3 to both sides.

y=-6x-57 is your answer.
