<u>Answer</u>
3.5 hours.
<u>Explanation</u>
The first step is to calculate the constant of proportionality.
t ∝ 1/n
t = k/n Where t = time, K= constant and n = number of people
t = k/n
k =tn
= 5×7 = 35
The equation becomes;
t = 35/n
for n = 10,
t = 35/10
t = 3.5 hours.
Answer:
C. 11
Step-by-step explanation:
This can be rewritten as
23 - 12
This is equal to 11.
Answer:
D. 54m
Step-by-step explanation:
by the side you can see that it is a right triangle with hypotenuse = 15
1/2(b)(h) = 1/2(9)(12) = 54
Answer:
f(x) = 3x²
Step-by-step explanation:
<u>Quadratic Function :- </u>
The function whose highest degree of variable is 2 is called a quadratic function .
- On looking at the given options , we see that the third options satisfies the definition of Quadratic Function . That is,
f(x) = 3x²
<h3>
<u>Hence</u><u> the</u><u> </u><u>third </u><u>option </u><u>is</u><u> </u><u>correct</u><u> </u><u>.</u></h3>
