Answer: Like the angles BAC (56°) and BDC has the same arc BC in the circumference, these angles must be congruent, then angle BDC must be equal to 56°.
Answer:
256 is the answer
Step-by-step explanation:
4×4×4×4=256.
When multiplying terms that have the same base (in this case,
) but different exponents, you can add their exponents to make them one term.
In this case, we can add the exponents of
:



A simplified version is
.
Check the picture below.
thus is at 0 = -16t² + 96t +640,

well, clearly it can't be a negative value for the elapsed seconds, so it can't be -4.
