Answer:
(A) 24 and 66
Step-by-step explanation
Complementary angles add up to 90 degrees
Supplementary angles add up to 180 degrees
(A) 24 + 60 = 90
These 2 angles sum to 90, so therefore they are complementary
(B) 56 + 124 = 180
These 2 angles sum to 180, so they are supplementary, not complementary
(C) 34 + 66 = 100; 34 + 56 = 90
While 34 and 56 sum to 90 degrees, 34 and 66 sum to 100, so this answer does not satisfy the question
(D) 56 + 124 = 180; 66 + 114 = 180
Both of these angle pairs are supplementary, so they do not satisfy the answer to the question
Verify each of the solutions by substituting them back into the original equation <span><span>log<span>(−2a+9)</span>=log<span>(7−4a)</span></span><span>log<span>(-2a+9)</span>=log<span>(7-4a)</span></span></span> and solving. In this case, all solutions were found to be valid.<span>a=−<span>1</span></span>
Answer:
The second term:
c(2) = 30
Step-by-step explanation:
c(n) = c(n - 1) + 10
c(1) =20
c(2) = c(1) + 10 = 20 + 10 = 30
Answer:
= 3.0
Step-by-step explanation:
represents the median of the data set.
From the box plot the median is the horizontal line inside the box and is positioned at 3.0
