The answer is 25.
Have a good night
We know that
cos²(theta)=0.21
sin²(theta)+cos²<span>(theta)=1
</span>sin²(theta)=1-cos²(theta)------> sin²(theta)=1-(0.21)-----> 0.79
sin(theta)=√0.79
sin(theta)=0.89
the answer is
the value of sin(theta) is 0.89
Answer:equal
Step-by-step explanation:
The probability that a random variable is greater than or equal to z standard deviations from the mean in a standard normal distribution he P(z≤a)+P(z>a)=1, so P(z>a)=1-P(z≤a)=1-.7116=.2884
1st: 5x-20+2x (distribute the 5 to the numbers in the parenthesis) distribution property
2nd: 7x-20 (add like terms aka 5x and 2x) I believe commutative property of addition
Finished!
Answer:
A
Step-by-step explanation:
The area in step one is
a²+b² but that does not equal (a+b)²
