Answer:
2nd option
Step-by-step explanation:
The 2 angles are corresponding and are congruent , so
3x + 27 = 129 ( subtract 27 from both sides )
3x = 102 ( divide both sides by 3 )
x = 34
Answer:
50 students play indoors
300 students play outdoors
Step-by-step explanation:
Divide the total number of students by 7 to find the number of them who play indoor.
350 / 7 = 50
Multiply 50 by 6 since 50 is just 1/7 and 6/7 is just multiplying that value by 6.
50 * 6 = 300
Best of Luck!
It’s B.29 I hope this helps and you have a great day:)
<h3>Answer: approximately 63.43 degrees</h3>
=========================================
Work Shown:
Locate the intersection points
f(x) = g(x)
x^2 + 2x + 1 = 1
x^2 + 2x = 1-1
x^2 + 2x = 0
x(x+2) = 0
x = 0 or x+2 = 0
x = 0 or x = -2
---------------------
Compute the derivative
f(x) = x^2 + 2x + 1
f ' (x) = 2x + 2
Then plug in each solution x value we found earlier
f ' (0) = 2(0) + 2 = 2
The slope of the tangent line at the intersection point (0,1) is m = 2
The tangent line is y = 2x+1
The angle between the lines y = 1 and y = 2x+1 is arctan(2) = 63.43 degrees approximately
---------------------
Plug x = -2 into the derivative function
f ' (x) = 2x+2
f ' (-2) = 2(-2)+2
f ' (-2) = -2
The slope of the tangent line at (-2,1) is m = -2
The tangent line here is y = -2x-3
The angle between the lines y = 1 and y = -2x-3 is also 63.43 through similar reasoning as before.
