Answer:
Step-by-step explanation:
The altitude falls in the middle of the line.
So, the point at which it falls in the bottom line is the midpoint, so the length of the blue triangle would be 6/2 = 3
So, the blue triangle has length of 3 and height of H and hypotenuse of 10.
Now, we will use Pythagorean Theorem to solve for H. The theorem is:
Leg^2 + Another Leg^2 = Hypotenuse^2
We know one leg of the triangle is 3 and another leg is H and hypotenuse is 10, so we substitute and solve:
This is the exact answer for H
Answer:
Reflect the graph of f across the y-axis and then reflect across the x-axis.
Step-by-step explanation:
Reflection rules:
Reflection over x -axis:(x,y)→(x,-y)
Reflection over y-axis : (x,y)→(-x,y)
Graph:
We are given that the graph of f into the graph of g.
and
Reflect over y axis.
Reflected graph
Reflect the obtained graph over x axis
So, Option B is true
Hence Reflect the graph of f across the y-axis and then reflect across the x-axis.
The teacher probably wants you to multiply cause area refers to that
Answer:
Step-by-step explanation:
Given that
S(x) stand for "x is smart".
Y(x) stand for "y is young".
C(x) stand for "x is a CS Major"
1) All CS majors are smart : C(x) ⇒ S(x)
2) Some CS majors are smart and not young.: There exists a∈C(x) such that a ∉ Y(x)
3) No young college students are CS majors.: ~Y(s)⇒CS(x)
