Answer:
6 miles all together in them 8 days
Step-by-step explanation:
3/4 times 8
So her trainer travels 20miles(using the Pythagoras theorem) while she travels 12+16=36 so the answer is 36-20=16
The Empire State Building, the Sears Tower, the Canadian National Tower - each of these structures was the tallest in the world at the time they were (Option D) built.
<h3>What is sentence correction?</h3>
Sentence correction or sentence improvement is a type of grammatical practice where a sentence is given with a word or a phrase that requires grammatical changes or improvement.
Now,
- Here, we are talking about each of the mentioned structures.
- By grammar, everything used for them must be singular.
- But as mentioned in the sentence in part D, the plurals "they were" are used, which is the faulty part of the sentence.
Hence, Option D is the correct part that needs correction; the correction would be: "it was built."

Answer:
See below.
Step-by-step explanation:
1. x = e^(x/y) Taking logs:
log x = x/y
x = y log x
Differentiating:
1 = dy/dx log x + y * 1/x
dy/dx log x = (1 - y/x)
dy/dx = (1 - y/x) / log x
dy/dx = ((x - y)/ x) / log x
dy/dx = (x - y) / x log x)
2. y^x = e ^(y - x)
Taking logs:
x log y = y - x --------------(A)
y = x + x logy --------------(B)
dy/dx = 1 + x * 1/y * dy/dx + 1*logy
dy/dx - dy/dx * x/y = 1 + log y
dy/dx ( (x - y) y)) = 1 + log y
dy/dx = y(1 + log y) / (y - x)
Using (A) and (B) :-
dy/dx = x(1 + logy)(1 + logy) / x logy The x's cancel, so:
dy/dx = (1 + logy)^2 / log y

Answer:
C. 15
Step-by-step explanation:
A straight line equals 180°.
The angles are:
(6x + 10) +
(6x - 10)
+10 and -10, cancel each other out.
Now we are left with:
(6x) +
(6x)
6 + 6 = 12, so we have 12x
180° ÷ 12 = 15°
