Answer:
B) y = 9 x has Proportionality Constant = 9
Step-by-step explanation:
Two quantities P and Q are said to be PROPORTIONAL if and only if:
P ∝ Q ⇔ P = k Q ⇔
Here, k = PROPORTIONALITY CONSTANT
Given : k = 9
Now, let us consider the given expressions in which x ∝y
y = 81/3 x
Here,
So, here Proportionality Constant ≠ 9
y = 9 x
Here,
So, here Proportionality Constant = 9
y = 3 x
Here,
So, here Proportionality Constant ≠ 9
y = 1/9 x
Here,
So, here Proportionality Constant ≠ 9
Hence, only y = 9 x has Proportionality Constant = 9
<u>Answer:</u>
- The length of the hypotenuse is 40 mm.
<u>Step-by-step explanation:</u>
<em>We can solve for 'a' using Pythagoras theorem. Let's solve it.</em>
- 10² = 5² + a²
- => 100 = 25 + a²
- => a² = 75
- => a = 8.660
- => a = 8.7
Hence, the length of the hypotenuse is 8.7 m.
Hoped this helped.
