Answer:
2nd
Step-by-step explanation:
The blocks from the bottom up are: 123. Each column has one 1 one 2 and one 3. So only 2 can be the right answer.
I'm not that familiar with these problems, check my answer just in case.
Domain is the numbers you can use
see we have rom x<-3 and x≥-3
therefor it is all real numbers for the domain
domain=all real numbers
and the range is the output
for all numbers less than -3, we have x+4, so -10+3=-7, so it extends infinetely in negative direction
and for x^2+6, you start with -3 which ends with (-3)^2+6=9+6=13, after that it gets bigger
so therefor the range is
from -∞ to -7, not including -7 and from 13 to positive infinity
in interval notation
(-∞,-7)U[13,∞)
domain=all real number
range=(-∞,-7)U[13,∞) or all real numbers except all numbers c, such that -7≤c<13
Answer: Line DE is the adjacent while line EF is the opposite.
Step-by-step explanation: This is a right angled triangle and the reference angle has been marked at point D. If you drew a line from that angle it would touch the triangle at line line EF. It’s facing the reference angle and that’s why it’s called the “opposite.”
The line that lies between the reference angle and the right angle is called the adjacent and that’s line DE in this triangle. The hypotenuse has already been identified for you, and that’s the line that’s opposite the right angle (it’s always the longest side).
**Please note that the opposite and adjacent ALWAYS depends on where the reference angle is positioned.
Answer:
x = 3
Step-by-step explanation:
The external angle of a triangle is equal to the sum of the 2 opposite interior angles
∠ QRT is an external angle, thus
∠ QRT = ∠ RTS + ∠ RST, substitute values
45x = 25x + 57 + x
45x = 26x + 57 ( subtract 26x from both sides )
19x = 57 ( divide both sides by 19 )
x = 3
