Answer: here
Step-by-step explanation:riangles QST and RST are similar. Therefore, the following is true:
q s
--- = ---- This results in 10q=rs.
r 10
Also, since RST is a right triangle, 4^2 + s^2 = q^2.
Since QST is also a right triangle, s^2 + 10^2 = r^2.
4 s
Also: ---- = ----- which leads to s^2 = 40
s 10
Because of this, 4^2 + s^2 = q^2 becomes 16 + 40 = 56 = q^2
Then q = sqrt(56) = sqrt(4)*sqrt(14) = 2*sqrt(14) (answer)

They are both equal to each other
The answer is C. Use the quadratic formula to solve it and you should be just fine!
Remember that the domain is all possible x values of a function. In the case of sine and cosine functions, they go up and down (like waves), but go on forever. Therefore, the domain is all real numbers.
Correct Answer: B, All Real Numbers

Answer:
see below
Step-by-step explanation:
defining variables:
since you are trying to find t shirt cost and jeans cost, your variables would be
the cost of the t shirt and the cost of jeans, denoted by any variable you want.
I'll use x and y since they are the most common variables (x = shirt y = jeans)
Equation
4 shirts + 5 jeans = 160 dollars
4x + 5y = 160 (the cost of 4 shirts + the cost of 5 jeans is $160)
the cost of 2 shirts + 6 jeans = $150
2x + 6y = 150
