Answer:
dont know what the expressions are but imma just guess its doing scientific notation, 8.73 x 10^-11
Step-by-step explanation:
Area of square = 24cm²
⇒ Length = √24
Find the diagonal of half the square:
a² + b² = c²
c² = (0.5√24)² + (√24)²
c² = 6 + 24
c² = 30
c = √30
The diagonal of half of the square is the radius of the circle.
⇒ radius = √30
Area of the semicircle = 1/2πr² = 1/2π(√30)² =15π
Answer: 15π²
Answer:
It should be 261 degrees.

Step-by-step explanation:
We have a sum of money ($6000) compounded daily at an annual interest rate of 8.5% for 6 years.
If the interest is compound daily, and we take a m=365 days a year (or 365 subperiods m), the daily nominal interest rate is:

Then, we can express the final valueo of $6000 compounded daily at an annual interest rate of 8.5% for 6 years as:

Answer:
The method used is substitution method
x = 2, y = -6
Step-by-step explanation:
Given the simultaneous equation
Y = −3x ..... 1
4x + y = 2 ... 2
Substitute equation 1 into 2
4x + (-3x) = 2
4x - 3x = 2
x = 2
Get y:
y = -3x
y = -3(2)
y = -6
<em>Hence the value of (x, y) is (2, -6)</em>
