Answer:
(5x + 7y)² = 25x² + 70xy + 49y²
Step-by-step explanation:
(5x + 7y)² = 25x² + 70xy + 49y²
Because,
(5x + b)² = (5x)² + 2(5x)(b) + b²
2(5x)(b) = 70xy
b = 7y
b² = (7y)² = 49y²
Answer:
1st term = 14
2nd term = 29
3rd term = 44
Step-by-step explanation:
1st term = 3 x (5 x 1) - 1
= 3 x 5 - 1
= 15 - 1 = 14
2nd term = 3 x (5 x 2) - 1
= 3 x 10 - 1
=30 - 1 = 29
3rd term = 3 x (5 x 3) -1
= 3 x 15 - 1
= 45 - 1 = 44
Answer:
Example: Find the radian measure of the angles −70° and 120°.
Solution: To find the radian measure of −70° we multiply −70 by the conversion factor /180. We get
Similarly, for 120° we obtain
Note that when we write an angle as a fractional amount of , for example 2/3 times we write the result either as the numerator times divided by the denominator or as the fraction times . So the two values
are equivalent ways of writing the same number. You will see both methods used in the text and in the exercises.
Example: Find the degree measure of /12.
Solution: The conversion factor for going from radians to degrees is 180/. We get
and so the radian measure of /12 is 15°.
