jolli1 [7]
Use the attached formula.
exp = [log (total / principal) / n*years]
where "n" is compounding periods per year
exp = [log (7,194.66 / 2,978.41) / (365*21)
exp = log ( <span> <span> <span> 2.4156042989 </span> </span> </span> ) / 7,665
exp = log ( <span> <span> 2.4156042989 </span> </span> ) / 7,665
exp = 0.38302579382 / 7,665
exp = <span> <span> <span> 0.00004997074935681670 </span> </span> </span>

rate = (10^exp -1)* n
rate = (10^<span>0.00004997074935681670 -1) * n
</span>rate = <span><span>(1.0001150685 </span> -1) * 365
</span>rate = <span>(.0001150685) * 365</span>
rate = <span> <span> <span> 0.0420000025 </span> </span> </span>
rate = <span>4.20000025 %
rate = 4.2 %

Yes, it's just that easy.  LOL

Assuming the conditions regarding the motion represented in the graph remain the same, determine the acceleration of the object
vovikov84 [41]

(a)

We can see that

this is a straight line

and this is the graph of velocity

we know that

acceleration is the derivative of velocity

so, slope of curve of velocity is acceleration

so, we will find slope of this line

We can select any two points

(0,4) and (5,7)

we can use slope formula

m=\frac{y_2-y_1}{x_2-x_1}

now, we can plug points

m=\frac{7-4}{5-0}

m=0.6

we know that slope of line is always constant irrespective of any value of t

so, acceleration will always be same irrespective of any value of t

so, we will get acceleration

a(t)=0.6m/s^2............Answer

(b)

we can see that acceleration is constant

and we know that

derivative of constant is always 0

so, instantaneous rate of acceleration at t=10s is 0........Answer

Find the difference in the volume and total area of a cylinder with both a radius and height of 1. R = 1, h = 1 The number of sq
Vikentia [17]

Answer:

The difference in the volume of cylinder and total surface area of cylinder =.

The number of sq units of total area exceeds the number of cu.units in the volume .

Step-by-step explanation:

Given radius of cylinder =1 unit

Height of cylinder= 1 unit

We know that  formula of volume of cylinder =

Where r= Radius of  the cylinder

           h= Height of the cylinder

By using this formula  we can  find the volume of cylinder

volume of cylinder = =

By using this formula we can find total surface area of cylinder

Total surface area of cylinder =  sq units .

Difference between volume of  cylinder and total surface  area of cylinde= =

Total surface area of cylinder  - volume of cylinder=

Total surface area of cylinder =  + volume of cylinder

Hence, the number of sq units of total surface area exceed the number of cu.units in the volume by .
