Answer:
126 ft
Step-by-step explanation:
Calculate the area (length x height)
14 x 9 = 126
Step-by-step explanation:
Notice that KM = 0.5BC, KL = 0.5AC
and ML = 0.5AB. Therefore the perimeter of triangle KLM is half of the perimeter of triangle ABC. => 0.5 * 24cm = 12cm.
Each of the 3 purple triangles have perimeters which are 1/4 of the perimeter of triangle ABC. (Their vertices are midpoints of midpoints => 1/2 * 1/2)
Perimeter of 3 small purple triangles
= 3 * [24cm * (1/4)]
= 3 * 6cm = 18cm.
Hence Total perimeter of shaded parts
= 12cm + 18cm = 30cm.
Answer:
a P(x) = Q(x)
b. R(x) = Q(x)
c. R(x) = P(x)
d. Yes
Step-by-step explanation:
This is a statement of logical connectives.
a P(x) = Q(x)
b. R(x) = Q(x)
c. R(x) = P(x)
d. Yes, (c) follows from (a) and (b)
Reasoning:
(c) is equivalent to ∀x ¬ P(x) ∨ Q(x)
Proof:
Follow the tautology (X→Υ) Ξ(¬x∨Υ)
This gives X: R(x) ∧ ¬ P(X)
Answer: Top right corner
This graph shows a curve going through x = -1, x = 0 and x = 4 on the x axis. These are the three roots or x intercepts.
The graph in the bottom right has a root of x = -4, but that's not one of the listed roots in the instructions. So we rule this graph out.
The other two graphs only have two roots, and not three, so we rule them out as well.
The study of proper reasoning or excellent arguments is known as logic. O is taller than two people, M and P.
<h3>What is Logic?</h3>
The study of proper reasoning or excellent arguments is known as logic. It is sometimes described narrowly as the study of deductively valid deductions or logical facts.
M is taller than only P → M > P
O is taller than P and M both → O > M&P
O is smaller than l and n both but not m. → I&N > O > M
N is not the tallest one. I >N
Now, if we sum up all the conditions then we can arrange the 5 people from tallest to shortest as,
I > N > O > M > P
Hence, O is taller than two people M and P.
