Answer:
64:1
It doubles every 10 minutes, so it multiplies by two 6 times in an hour. 1x2x2x2x2x2x2 = 64
Answer:
157 cm^2
Step-by-step explanation:
1) find the radius
radius = side of the square /2 = 10 /2 = 5 cm
2) notice that four semicircles are equals to two circles
3) find the area of the shaded region
A = radius^2 x pi x 2 = 5^2 x pi x 2 = 157 cm^2 (round the nearest whole number)
Step-by-step explanation:
Consider LHS
Apply quotient identies
Multiply the fraction and sine.
Make cos x a fraction with cos x as it denominator.
so
Pythagorean Identity tells us sin squared and cos squared equals 1 so
Apply reciprocal identity.
No, because if they were equal the second equation should be 225/(15x3), not (15/3).
