Answer:  The required value of the expression at x = 0 is 7.

Step-by-step explanation:  We are given to evaluate the following expression for x = 0.

g(x)=7+(-4x^2)~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)

To evaluate, we must substitute x = 0 in the given expression.

So, putting x = 0 in equation (i), we get

g(x)\\\\=7+(-4x^2)\\\\=7-4x^2\\\\=7-4\times 0^2\\\\=7-0\\\\=7.

Thus, the required value of the expression at x = 0 is 7.

4 students is what percentage of 20 students?2 doctors is _____% of 25 doctors.
Ray Of Light [21]

In both cases, we can use a rule of three.

<h2>First part</h2>\begin{gathered} 20\text{ students}\rightarrow100\text{\%} \\ 4\text{ students}\rightarrow x \\ x=\frac{4\text{ students}\cdot100\text{\%}}{20\text{ students}} \\ x=\frac{4\cdot100\text{\%}}{20} \\ x=\frac{400\text{\%}}{20} \\ x=20\text{\%} \end{gathered}

Therefore, 4 students correspond to 20% of 20 students in total.

<h2>Second part</h2>\begin{gathered} 25\text{ doctors}\rightarrow100\text{\%} \\ 2\text{ doctors}\rightarrow x \\ x=\frac{2\text{ doctors}\cdot100\text{\%}}{25\text{ doctors}} \\ x=\frac{2\cdot100\text{\%}}{25} \\ x=\frac{200\text{\%}}{25} \\ x=8\text{\%} \end{gathered}

Therefore, 2 doctors correspond to 8% of 25 doctors in total.
