Answer:

Step-by-step explanation:

I am not completely sure.

if x=4 then it would be 12

if x=6 then it would be 18

if x=9 then it would be 27

if x=10 then it would be 30

the side is shorter than 19 but definitely longer than 6. To me, it looks like a little more than double, more of triple and 6 times 3 is 18.

Answer:

$f_{1} :Z \rightarrow Z$ is one to one mapping, it is not onto mapping

Step-by-step explanation:

$f_{1} :Z \rightarrow Z\\ f_{1} (x) = x^{3}$

f₁(x) is one to one mapping

Let $x, y \epsilon Z$

f₁(x) = f₁(y):

x₁³ = y₁³

f₁(x) is not onto mapping

Example: If f₁(x) = 7,

x₁³ = 7

$x_{1} = \sqrt[3]{7}$

x₁ is not an element of Z

$f_{1} :Z \rightarrow Z$ is one to one mapping, it is not onto mapping

Answer:

Step-by-step explanation:

The number of days has gone down by a factor of 15/24. The number of workers is inversely proportional, so must increase by a factor of 24/15 = 8/5.

(5 workers) × (8/5) = 8 workers

8 workers are needed to complete the project in 15 days.
