Is Nakafa really free?

Yes. Core content and 1 complete Tryout are free. Pro is required to start another Tryout set or repeat one, use premium Nina models, and get 3,000 AI credits each month. Basic learning materials stay free of paywalls.

What AI models can I use?

Everyone can use Nakafa Lite and Nakafa Pro. Credits decide how much you can use each model.

What subjects and grades do you cover?

We cover K-12 through university. Mathematics, Physics, Chemistry, Biology, Computer Science, and more. From elementary basics to advanced university courses.

Yes. We do not sell your data. AI conversations are processed securely. You can delete your chat history anytime. We are privacy-first by design.

Can schools use Nakafa?

Absolutely. We offer custom solutions for classrooms and institutions. Contact founder for LMS integration, student management, and custom branding.

How does Nakafa ensure content accuracy?

All content is created by qualified contributors and reviewed by the community. Our source-available approach means anyone can inspect materials and propose improvements. Practice exercises include explanations so you learn from mistakes, not just scores.

Given the operation $\triangle(a, b) = ka + \frac{b}{m}$ where $k$ and $m$ are positive integers. If $\triangle(2, 4) = 8$ and $\triangle(3, 5) = 11$ , then the value of $\triangle(5, 9)$ is ....

If you are still unsure, Nina already knows which part you mean

For the operation $\triangle(a,b)=ka+\frac{b}{m}$ , we know $\triangle(2,4)=8$ and $\triangle(3,5)=11$ . How do I find $\triangle(5,9)$ ?

Subtract the first equation from the second:

$k+\frac{1}{m}=3$

Because $k$ and $m$ are positive integers, $\frac{1}{m}$ can only be an integer when $m=1$ . That makes $k=2$ .

Put both values into the final operation:

$\triangle(5,9)=5(2)+\frac{9}{1}=19$

So $\triangle(5,9)=19$ .

Motion becomes easier to understand when you can see it for yourself

Horizontal component: $v_{0x}=20\text{ m/s}$
Vertical component: $v_{0y}=34.6\text{ m/s}$
Peak time: $t=3.5\text{ s}$
Flight time: $T=6.9\text{ s}$
Range: $R=138.6\text{ m}$
Velocity at two seconds: $\vec{v}=\langle 20, 14.6\rangle\text{ m/s}$
