890×(1+0.187÷12)^(12)−890×(1+0.125÷12)^(12)=63.61....answer
The solution is <span>B. π/12+nπ
</span>proof
sinx cosx = 1/4 is equivalent to 2 <span>sinx cosx = 1/2 or sin2x =1/2
so 2x = arcsin(1/2) = </span>π/6 + 2nπ, so x = π/12+nπ
Given:
Area of rectangle = 
Width of the rectangle is equal to the greatest common monomial factor of 
.
To find:
Length and width of the rectangle.
Solution:
Width of the rectangle is equal to the greatest common monomial factor of is
Now,
So, width of the rectangle is 
.
Area of rectangle is
Taking out GCF, we get
We know that, area of a rectangle is the product of its length and width.
Since, width of the rectangle is , therefore length of the rectangle is 
.
Anthony ran 5.5 miles each day after school
Let x represent the amount of mile he covered at the park after school. Since he ran 1.5 miles each day before school, the total distance covered each day is:
Total distance covered each day = Distance ran before school + Distance ran after school
Total distance covered each day = 1.5 + x
Since he ran for 4 days in a week, hence:
Total distance ran in a week = 4 days × (1.5 + x)
Total distance ran in a week = 4x + 6
But at the end of the week he ran 28 miles, hence:
4x + 6 = 28
4x = 22
x = 5.5 miles
Hence Anthony ran 5.5 miles each day after school
