Answer:
The surface area is
Step-by-step explanation:
we know that
The surface area of the square pyramid is equal to
where
b is the length side of the square base
h is the height of the lateral triangular face
we have
Applying Pythagoras Theorem find the value of h
substitute in the formula
Answer:
(12 ÷ 4) × (18 ÷ 6)
Step-by-step explanation:
(12 ÷ 4) × (18 ÷ 6)
If we solve this or simply this, we would get 9 as our result.
Let's solve and see. Mind you, we've used each of the given numbers just once in the expression.
Thus:
(12 ÷ 4) × (18 ÷ 6)
Solve the parentheses first
3 × 3 = 9.
Therefore,
(12 ÷ 4) × (18 ÷ 6) = 9
Question 1
Let the scale factor be k.
Then, we have the mapping
This implies that:
We equate any corresponding component find the value of the scale factor k.
6k=2
Hence the scale factor is
Question 2:
The midpoint of any two points can be calculated using the formula;
We want to find the midpoint of (-8, 5) and (2, -2).
The midpoint is:
4 + 5(x - 7)²
4 + 5(8 - 7)²
4 + 5(1)²
4 + 5(1)
4 + 5
9
