Answer:
At x = 7 and x= 1
Step-by-step explanation:
Set each equation equal to 0 and solve.
x - 7 = 0
x = 7
x-1 =0
x = 1
The sum of the first n terms in a geometric sequence given the first term (a1) and the common ratio (r) is calculated through the equation,
<span>Sn </span>= (<span><span><span>a1</span>(1−<span>r^n</span>) / (</span><span>1−r)
Substituting the known terms,
Sn = (20)(1 - (1/4)^4)) / (1 - 1/4)
Sn = 26.5625
Thus, the sum of the first four terms is 26.5625. </span></span>
Since you have two angles that measure 45 degrees. Those 2 equal 90 degrees altogether. Since a triangle measures 180 degrees, you take 180-90 because you already have 2 angles and are trying to find the last one. Then this makes the last angle 90 degrees.
Answer:
Correct answers:
A. An angle that measures 
radians also measures 
C. An angle that measures 
also measures 
radians
Step-by-step explanation:
Recall the formula to transform radians to degrees and vice-versa:
Therefore we can investigate each of the statements, and find that when we have a radians angle, then its degree formula becomes:
also when an angle measures , its radian measure is:
The other relationships are not true as per the conversion formulas
Answer:
A and B are correct
