Answer:
honestly i think it might be (C)
Step-by-step explanation:
Put this into a scientific calculator
1/3 x pi x 18 squared x 16
Answer:
y = -x + 2
Step-by-step explanation:
Use the point-slope formula y - k = m(x -h):
y - [-1] = -1(x - 3), or
y + 1 = -x + 3, or
y = -x + 2
Question 13: The answer is D
Question 7: The answer is C
Question 14: The answer is B
And the question for the last Pic, the correct graph is B.
Answer:
<h2>m∠ACE = 90°</h2>
Step-by-step explanation:
Figure Interpretation:
m∠CBA + m∠CDE = 180
m∠BCA = (180-m∠CBA)/2
m∠DCE = (180-m∠CDE)/2
=======================
Then
m∠BCA + m∠DCE = (180-m∠CBA)/2 + (180-m∠CDE)/2
= [360-(m∠CBA+m∠CDE)]/2
= [360 - 180]/2
= 90
finally,
m∠ACE= 180 - (m∠BCA + m∠DCE)
= 180 - 90
= 90
