Answer:

  59°

Step-by-step explanation:

The law of cosines tells you ...

  h² = f² +g² -2fg·cos(H)

Solving for angle H gives ...

  H = arccos((f² +g² -h²)/(2fg)) = arccos(725/1400) ≈ 58.811°

  ∠H ≈ 59°

Answer:

294cm²

Step-by-step explanation:

Given the formula for surface area expressed as 6L^2

TSA = 6L²

Given that L = 7cm

Substitute

TSA = 6(7)²

TSA = 6 * 49

TSA = 294cm²

Hence the total surface area is  294cm²

Answer:

15,103.05

Step-by-step explanation:

Total amount in the saving account after 5 years in which the  annual interest, compounded continuously, is $15,103.85.

Compound interest is the amount charged on the principal amount and the accumulated interest with a fixed rate of interest for a time period.

The formula for the final amount with the compound interest formula can be given as,

[tex]A=P\times\left(1+\dfrac{r}{100n}\right)^{nt}\\[/tex]

Here, A is the final amount (principal plus interest amount) on the principal amount P of with the rate r of in the time period of t.

$13,000 is deposited into a savings account with an annual interest rate of 3% compounded continuously.

The amount in account after 5 years can be calculated with the above formula as,

[tex]A=13000\times\left(1+\dfrac{3}{12\times100}\right)^{12\times5}\\A=15101.02[/tex]

The total amount in the saving account after 5 years in which the  annual interest, compounded continuously, is $15,103..85.

Answer:

Measurement of AB = 8.6 units (Approx.)

Step-by-step explanation:

Given:

Coordinate of point A = (3 , 9)

Coordinate of point B = (8 , 2)

Find:

Measurement of AB

Computation:

Distance = √(X1 - X2)² + (Y1 - Y2)²

Measurement of AB = √(3 - 8)² + (9 - 2)²

Measurement of AB = √25 + 49

Measurement of AB = √74

Measurement of AB = 8.6 units (Approx.)
