Answer:

interest: 945, FV: 6345

FV= 323711.4, Interest: 226211.4

25.21 years

Step-by-step explanation:

question 1:

simple interest formula

PV(1+it)

30 months is equal to 30/12 years or 2.5 (so t= 2.5)

5400(1+.07*2.5)= 6345

This is the future value, to find the interst subtract the present value

6345-5400= 945

2.)

future value of continously compounding interst:

PV(e^(it))

97500*e^(.06*20)= 323711.4

finding the interest is the same as the last one

323711.4-97500=226211.4

3.)

same formula

let x= time in years

$30000=7500e^{.055x}\\4=e^{.055x}\\\ln(4)=.055x\\x=25.20535202$

i guess we can round this to 25.21

Heron’s formula: Area = An equilateral triangle has a semiperimeter of 6 meters. What is the area of the triangle? Round to the

nordsb [41]

Answer:

7 m^2

Step-by-step explanation:

$s = \dfrac{a + b + c}{2}$

$A = \sqrt{s(s - a)(s - b)(s - c)}$

$s = 6$

$\dfrac{a + b + c}{2} = 6$

$a = b = c$

$\dfrac{a + a + a}{2} = 6$

$3a = 12$

$a = b = c = 4$

$A = \sqrt{6(6 - 4)(6 - 4)(6 - 4)}$

$A = \sqrt{6(2)^3$

$A = \sqrt{48}$

$A = 6.92820...$

$A = 7~m^2$

Help please!!!!!! And explain ur answer.. I will mark as BRAINLIEST

Temka [501]

Answer:

Nu 4550

Step-by-step explanation:

Commission of 5% only applies to the first 70,000 so

$70,000*\frac{5}{100} = 3500$

That leaves 15,000 left in sales where the 7% commission applies.

$15,000*\frac{7}{100}=1050$

Adding these two together we get a total of

$3500 +1050=Nu4550$

In 2014, the enrollment at Luling High School was 625 students. In 2015, the enrollment grew to 650. By what percentage did the

Inessa05 [86]

Answer:

$\%Increase = 4\%$

Step-by-step explanation:

Given

$Initial\ Population = 625$

$Final\ Population = 650$

Required

Determine the percentage population increase

This is calculated using the following formula:

$\%Increase = \frac{Final - Initial}{Initial} * 100\%$

$\%Increase = \frac{650 - 625}{625} * 100\%$

$\%Increase = \frac{25}{625} * 100\%$

$\%Increase = \frac{25* 100\%}{625}$

$\%Increase = \frac{2500\%}{625}$

$\%Increase = 4\%$

<em>Hence, there is a 4% increment from 2014 to 2015</em>
