Prove axial symmetry?
How would I break number b) here?
Hi! I somehow misplaced my calculator. Before I enter a calculation, it says "Check Calculation" in the bottom right corner. When I try to calculate something, like 4+4, it displays 4+4=0 => Incorrect.
a) 50 liters of seawater weigh 51 kg. Imagine you pour 50 liters of it into a plastic balloon, seal it tightly, and hang it from a rope into the sea. Once it's completely submerged, how much force would you need to pull on the rope to prevent it from sinking? a. 0 Newton b….
Hi, Why is the square root of 1/2 = 1/2 Γ square root of 2? I understand the partial root extraction, but I'm stuck here.

Plutonium-238 has a half-life of 87.74 years. Initially, it contains 400,000 atoms. How do you determine the decay law in the forms π(π‘) = π0 β π π‘ and π(π‘) = π0 β π πβπ‘ for the number of atoms still present as a function of time t (in years)? Would the correct answer be…
Hello everyone, I am writing a math KA on Monday with the topics of derivative and logarithm (see picture) I have the solution for every problem, but I find it extremely difficult to figure out the solution myself when I have the problems in front of me. For example, sometimes I have to plug x…
The symmetry criterion for axial symmetry is f(-x) = f(x) (always think of a parabola as a helpful rule of thumb) and in this specific case the following applies:
ο»Ώο»Ώ
The criterion is therefore met.
Thanks boss!
Aber in der Abgabe der bearbeitung nicht den 1/2 Faktor von der Abbildungsvorschrift vergessen π
Du setzt -x ein fΓΌr x in die Funktionsgleichung (das ist dann f(-x)). Achte dabei auf die Klammern! (-x)^Exponent
Wenn beim weiteren Vereinfachen f(x) herauskommt, hast du gezeigt, dass f(x)=f(-x) ist (hast halt bei f(-x) angefangen)
