Answer:
<em>Centimeters of crystal ( in real life ) = 0.5 cm</em>
Step-by-step explanation:
Let us plan out our steps, and solve for each:
1. Given the information, let us create a proportionality as such:
24 = 1 ⇒ x - <em>crystal size in real life</em>
12 x
3. Now let us cross multiply, and solve through simple algebra:
12 = 24 * x,
<em>x = 0.5 centimeters of the crystal in real life</em>
The expression is equal to:
So:
Answer: A = -27
B = 8
x = 3
y = 3
z = 9
Use the Pythagorus theorem
h^2=p^2+b^2
Here p and b are given
So, h= root under 18^2-7^2
h= 5 root under 11 or 16.58
(x-4)(x-5)
x² -4x -5x + 20
x² -9x + 20
Answer:
The answer is -33
Step-by-step explanation:
f(x) = 2x + 9; f(x) = -21
= 2(-21) + 9
= -42 + 9
f(x) = - 33
Thus, The answer is -33
