Hi there!
We can begin by multiplying by its conjugate:
Simplify using the identity:
Take the square root of the expression:
Multiply again by the conjugate to get a SINGLE term in the denominator:
Simplify:
Use the above trig identity one more:
Cancel out sinA:
Split the fraction into two:
Recall:
Simplify:
Rewritten:
15w^9 - 10w^7 + 12w - 7
Leading coefficient: 15
Degree of the polynomial: 9
We know that area of the square is 141 square feet. Therefore, we can figure out the dimension of square using formula for area as shown below:
We know that fencing is used along the sides of the square. Therefore, amount of fencing required will be equal to perimeter of square.
Hence, we can write:
Upon rounding to nearest foot, we get the amount of fencing required as 48 feet.
390 centimeters because u get centimetres out of meters u multiply by 100
To go from exponential to logarithmic, you can use
(exponential) =>
(logarithmic). With your specific equation, this would make
=>
, with that being your logarithmic form.
