R = {10; 15; 20}
S = {20; 25}
R U S = {10;15; 20; 25;
The first choice because it’s easier than having to add a bunch of numbers so S=(9)(2)(4)
Answer:
range = x ≤ 10
Step-by-step explanation:
Given in the question the function
f(x)=10-x^2
The range of a function is the complete set of all possible resulting values of the dependent variable F(x) after we have substituted the domain which is the values of x.
domain = set of all integers
range = x ≤ 10
f(x)=10-x²
since any negative value of x will be positive with squared so we will start from 0
f(0) = 10-0² = 10
f(1) = 10 - 1² = 9 = f(-1) = 10 -(-1)²
....and so on.
Answer:
9 gallons
Step-by-step explanation:
Since Khloe used 4 times (4x) as much paint for the kitchen and dining room walls, you can take the amount she used on the living room walls and multiply by 4:
Remember:
sec t=1/cos t
sin²t+cos²t=1 ⇒sin²t=1-cos² t
Therefore:
cos t(sec t- cost)=(cos t* sec t)- cos² t=(cos t * 1/cos t)-cos² t=1-cos²t=sin² t
Answer: cos t(sec t-cos t)=sin² t
