Answer:
1 and 0
Step-by-step explanation:
sin( 
) = 1, hence
sin³( ) = 1³ = 1
cos( ) = 0, hence
cos³ ( ) = 0³ = 0
Answer:
Step-by-step explanation:
To obtain the result of a fractions multiplication we need to multiply both numerators and the divide by the multiplication of the denomitators. In general, given a,b,c,d real numbers with b and d not zero, we have that
Substituting a,b,c and d for 8,15,2 and 13 we obtain that

Answer:
After 1.87 seconds the skateboarder is 8 ft from the bottom of the hill.
Step-by-step explanation:
The quadratic function d = –2*x² + 15 models a skateboarder’s distance, in feet, from the bottom of a hill x seconds after the skateboarder starts moving down the hill.
You want to know after how many seconds the skater is 8 feet from the bottom of the hill. That is, with the distance being 8 feet, you want to calculate the time t. Replacing in the expression d by the value of 8 feet:
8=–2*x² + 15
Solving:
8-15 = -2*x²
-7= -2*x²
(-7)÷(-2)= x²
3.5= x²
√3.5=x
1.87= x

Answer:
What is the value of x
Step-by-step explanation:
X<25 true or false ? This says x is less than 25
100<4x
Divide each side by 4
100/4 <4x/4
25<x
This says x is greater than 25
-3x>-75
Divide each side by -3, remembering to flip the inequality
-3x/-3 < -75/-3
x < 25
x is less than 25
10>35-x
Add x to each side
10+x >35-x+x
10+x>35
Subtract 10 from each side
10-10+x>35-10
x>25
x is greater than 25
