Answer:
3.5
Step-by-step explanation:
5.25 x 100/1.5 x 100 = 525/150 = 105/30 = 21/6 = 7/2 = 3.5
Explanation;
To solve an exponential Equation with different bases we need to the following steps;
1. Isolate the exponential part of the equation. If there are two exponential parts put one on each side of the equation.
2^x=3^x+1
2. Introduce logarithm of each side of the equation;
log 2^x = log 3^x+1
3. Then apply power property to rewrite the exponent.
x log 2= (x+1)log 3
4. Then Solve for the variable ;
x log 2 = log 3 + x log 3
x log 2 - x log 3 = log 3
x (log 2 - log 3) = log 3
and x = log 3 / (log 3 - log 2)
Answer:
They are skew lines.
Step-by-step explanation:
Which statement is true about lines a and b?
They are parallel lines.
They are perpendicular lines.
They are skew lines.
They will intersect.
As they both are in different directions they are skew lines .
Skew lines are not parallel neither they .They are also not co planar i.e they lie in different planes.
We have two plane Q and R . We have two line a and b on the different planes Q and R. Both planes are parallel but the lines a and b are in different directions. Therefore they are skew lines . They do not intersect and are also not parallel neither co planar.
