The distance between Pittsburgh and Cleveland is 200 miles
<u>Solution:</u>
Given that,
Plane travels from Pittsburgh to Cleveland in 2 hours
Average speed of plane = 100 miles per hour
<em><u>To find:</u></em> Distance between these two cities
<em><u>The relation between speed distance and time is given as:</u></em>

On rearranging the above formula, we get

Distance between these two cities = 

Thus both the cities are 200 miles apart
-12-(-8)
=-12+8
=-4
Double negative is the same as positive, so the two negatives cancel out to a plus sign.
Answer:
1
Step-by-step explanation:
SinA+sin²A= 1
sinA=1-sin²A
sinA=cos²A
cos²A= sinA
Now,
Cos²A+cos⁴A=cos²A+(cos²A)²
Replace cos²Awith sinA
= sinA+sin²A
=1
cos²A + cos⁴A=1
