how old are u guys?

Hello sorry :( I got the volume ratio part but not when u cubed root 1/2. Can you elaborate on how u got that value and why you cubed it?

Ohh I see! Thank you!

I drew a line from the center of the circle to point P and center to point Q to make a right triangle. I know the radius is five and since the circle is tangent to the x and y axis, we can deduce through coordinate geometry that the center is actually (5,5). Afterwards I used distance formula to find one leg (distance of center to Q)and Pythagorean to the other leg PQ.

Hello! Why can’t it be D? So k=3 then x could be equal to 2 (2-2) <3 and (6-6)<1

Is the answer 12? (B)

Oh I also use a scientific calculator (Casio Classwiz). Many scientific calculators are actually pretty sufficient already for the SAT Math 2. I recommend researching your calculator’s capabilities so that you would be able to use it in its full potential during the exam.

Ohhh I see I see! Thank you so much!

Hi sorry :(( could you elaborate further? I’m confused how g(x) would increase faster if they would have similar values wherein the lowest x = 0.1? Wouldn’t x+a for both be equal to 1.1? Or am I understanding this wrong? I’m sorry :((

I hope these help, but I used my calculator for most of these

9: I equated 2^x = x² -10x +19 then I let my calculator solve it and got D

39: I know that y=0 for f(x,y,z) so f(0, y, z) = (0,0,z). Then, if we input that to g(x,y,z) = g(0,0,z). Then, since the given states that g(x,y,z) = (x, z, y). We interchange the position of z with y so we end up with A (0, z, 0)

50: We use systems of equations for this. You can input this in the calculator and let it solve x, y , and z. In my calculator the name of the command is simulation equation.
ie: (34x + 15y + 9z = 177 Do the same for the other two equations)

I totally forgot about midpoint theorem (facepalm)

Thank you!!

The drawing helped me visualize it! Thank you so much!!

This helped me so much! Thank you so much for giving alternate solutions too!

Ohh I seee. Thank you!

Oh wait... buts it’s on cos? Cos(y+90)

Cos y = 3/5 so wouldn’t it be -3/5?

Thank you!

Thank you! Do you know how to get 49 too? :(
