Answer:

v²-3 where v equals 5 = 22

h^3÷ 8 where h equals 4 = 8

5(n-4) where n equals 10 = 30

4p ÷ 6 where p equals 12 = 8

6s + 17 where s equals 1/2 = 20

(3+g²) ÷ 6 where g equals 9 = 14

2f+1+6 where f equals 5 and g equals 4 = 15

(15+r) ÷q where r equals 9 and q equals 6 = 4

Step-by-step explanation:

Uhh it's kinda hard to explain but if you need a step-by-step explanation just comment that need one, I'd be happy to help :)

$425 is invested into an account that earns 6% compounded monthly. Find how much the account is worth in 15 years.
Masja [62]

Answer:

Future Balance

$1,044

Step-by-step explanation:

Compound interest is simple- It’s the interest you earn on both your original deposit and on the interest that your money earns. Compound interest allows your savings to grow faster over time.  In an account that pays interest, the earnings are typically added to the original principal at the end of every compounding period. That's often daily or monthly. Each time interest is calculated and added to the account, the larger balance results in more interest earned than before. This is what’s meant by compound interest. Note that high-interest savings accounts earn money faster than accounts with lower yields.

Water whose temperature is at 100∘C is left to cool in a room where the temperature is 60∘C. After 3 minutes, the water temperat
Tju [1.3M]

Answer:

21.68 minutes ≈ 21.7 minutes

Step-by-step explanation:

Given:

T=60+40e^{kt}

Initial temperature

T = 100°C

Final temperature = 60°C

Temperature after (t = 3 minutes) = 90°C

Now,

using the given equation

T=60+40e^{kt}

at T = 90°C and  t = 3 minutes

90=60+40e^{k(3)}

30=40e^{3k}

or

e^{3k}=\frac{3}{4}

taking the natural log both sides, we get

3k = \ln(\frac{3}{4})

or

3k = -0.2876

or

k = -0.09589

Therefore,

substituting k in 1 for time at temperature, T = 65°C

65=60+40e^{( -0.09589)t}

or

5=40e^{( -0.09589)t}

or

e^{( -0.09589)t}=\frac{5}{40}

or

e^{( -0.09589)t}=0.125

taking the natural log both the sides, we get

( -0.09589)t = ln(0.125)

or

( -0.09589)t = -2.0794

or

t = 21.68 minutes ≈ 21.7 minutes
