Answer:
D
Step-by-step explanation:
(-i)⁵ can be written as (-i)² * (-i)² * (-i). Since (-i)² is the same as i², this equals -1 * (-1) * (-i) which becomes -i.
No. For it to be in standard form the term with the largest exponent comes first. Standard form would be 6x^2-3x. It is a second degree polynomial because 6x is raised to the 2nd power. It would be a third degree polynomial if the largest degree was raised to the 3rd power.
The formula for finding the area of a circle can be written in many ways. If the radius is given, the formula is A=πr², where A=area, π=22/7 or 3.14, and r is the radius.
If the diameter is given, then the formula is A=1/4πd², where A is the area, π is 22/7 or 3.14 and d is the diameter
Given that the diameter is 46 inches and π=22/7 or approximately 3.14, the formula we can use is A=1/4πd² where A=area, π is 22/7 and d is 46
A=1/4*22/7*46*46
A=16662.57 inches² (It is rounded to nearest hundredth)
Carly's number is 36.5 and Henry's number is 40.5
To mountains took 9 Hrs at x mph where x = No of miles to mountains
No of miles travelled = 9x
From mountains took 4 hours at (x+40) mph
No of miles travelled = 4(x+40)
Therefore 9x=4(x+40) thus 9x=4x+160 thus x=32 = distance Charmaine lives from the mountains
