Hi there!
Recall the power rule:
Rewrite the function for ease of differentiation:
Use the power rule:
Take the derivative once more:
Rewrite:
Sinx = cosb => x + b = 90 <=> b = 90 - 47 = 43o
Answer:
Step-by-step explanation:
9th square number = 81
5th square number=25
81-25=56
56 is a multiple of 8 as 8 x 7=56
Answer:
1 If the equations do not involve fractions or decimals, and you have a good visual understanding of linear equations, graphing on the coordinate plane is a good option.
2 Whenever one equation is already solved for a variable, substitution will be the quickest and easiest method.
3 Elimination is best used when both equations are in standard form (Ax + By = C). Elimination is also the best method to use if all of the variables have a coefficient other than 1.
Answer:
98 degrees
Step-by-step explanation:
first find angle G
53 + 45 + G = 180
subtract 45 and 53 from both sides
G = 82
angle g is supplementary (add up to 180) to x
x +82 = 180
subtract 82 from both sides
x = 98
