By definition of the trig functions,
We have 
, so 
, and 
, so 
.
Just to check: we should have
by the Pythagorean theorem. Indeed,
Answer:
Either way, it gives us the prime factorization for 50 that is 5 x 5 x 2. The prime factorization of 50 can be expressed using exponents as 5^2 x 2.
Step-by-step explanation:
Answer:
Length is 90yards and width is 60yards
Step-by-step explanation:
Perimeter= 2( length+width)
let the width be x
then the length will be 30 + x
300 = 2(30+x+x)
150 = 30 + 2x
120= 2x
x = 120/2
x = 60 yards
length= 30+x
= 30 + 60
= 90yards
Answer:
525,000 N
Step-by-step explanation:
Since Force is mass multiplied by acceleration, you have to create the equation 25000*21 m/s^2.
25000*21 = 525000
She hit the parked car with 525,000 Newtons of force.
3/5 of fifteen is 9 because that's the same as saying (3/5)*15 = (45/5) = 9. Since 3/5 animals are dogs, 2/5 aren't, and 15 - 9 leaves 6 animals that aren't dogs.
