If the cosine is 1/2, and the angle is acute, then the angle is 60 degrees. Using the rules for a 30-60-90 right triangle, hyp=2 times the short leg. So 7/2= 3.5.
The solution to 4 superscript log subscript 4 baseline (x 8) baseline = 4 squared for the variable <em>x </em>is 8.
<h3>What is the exponent of log rule?</h3>
The exponent of the log rule says that the raising a logarithm with a number to its base is equal to the number.
For example, let <em>k</em> is the number and <em>a </em>is the base. Thus,

The logarithmic equation given in the problem is,

Compare the equation with the expression of exponent of log rule, we get,

Thus, the solution to 4 superscript log subscript 4 baseline (x 8) baseline = 4 squared for the variable <em>x </em>is 8.

Answer:
<u>No</u>
Step-by-step explanation:
3/5 or 3 ÷ 5 = 0.60
6/7 or 6 ÷ 7 = about 0.8571
these two numbers/decimals are obviously not the same, making them inequivalent
Answer:
y=8-x→y+x=8
2x²+xy=-16→x²+xy=-x²-16
→x(x+y)=-x²-16→8x=-x²-16→x²+8x+16=0
→(x+4)²=0→x=-4→y=12
