Answer:
Using 3.14 as pi, the answer would be 56.52, and using just pi (as in the input on a calculator) would be 56.54867.
Step-by-step explanation:
The equation for circumference of a circle is C = πd, C representing the circumference and d representing the diameter. Since the equation shows the radius, the equation can also be C = 2πr, since the radius is half of the diameter. Multiply nine by two to get eighteen. 18 times 3.14 = 56.52.
Answer:
SinL = 7/25
CosL = 24/25
TanL = 7/24
Step-by-step explanation:
Find the diagram attached.
Using SOH CAH TOA in trigonometry identity to find the sinL, cosL and TanL
Note that the hypotenuse is the longest side = 25
The opposite will be the side facing the acute angle L
Opposite = 7
Adjacent = 24
For SinL
sinL = Opposite/Hypotenuse {SOH}
SinL = 7/25
For cosL:
CosL = Adjacent/Hypotenuse{CAH}
CosL = 24/25
For tanL:
TanL = Opposite/Adjacent {TOA}
TanL = 7/24
Answer:
Maximum value of the function is 4.
Step-by-step explanation:
Given function of simple harmonic motion is .
Now we need to find about what is the maximum value of .
We know that value of sine function varies from -1 to 1.
that means for any value of t, maximum value of sine function is 1.
Hence maximum value of the function is 4.
B describes an unknown quality.
This is because the number of pages in the book is not defined. For all we know, the book could be 20 or 2000 pages.

Answer:
Here are the answers. Hope this helps you!
Step-by-step explanation:
11/12*9/22 = rational (as the solution is 33/88 which is in p/q form with q not equal to 0 and p and q as integers.)
√5 *8 = 8√5 = irrational
3 + √17 = irrational (sum of a rational and irrational number is always irrational)
√3*√12 = √36 = 6= rational number
π - 2π = -π = irrational (since π is irrational)
-3/8 + 3/5 = -15+24/40 = 9/40 = rational
√6/2 - 1/2 = 1/2*√6 - 1 * 1/2 = 1/2 (√6 - 1) = irrational (in this case difference is irrational and the product is clearly irrational as well).
