Answer:
Step-by-step explanation:
The 9 in 95 tells us how many tens are in the number 95.417; the 5 tells us how many ones, and the 4 how many tenths. And so on.
Thus,
95.417 = 9*10^1 + 5*10^0 + 4*10^(-1) + 1*10^(-2) + 7*10^(-3)
is 95.417 in expanded form, with each digit multiplying a power of 10.
Answer:
A
Step-by-step explanation:
Check the solution by substituting x = 
into the left side of the equation
2sin²x - sinx - 1
= 2sin²( ) - sin ( ) - 1
= 2(1)² - 1 - 1
= 2 - 1 - 1
= 0
= right side
is therefore a solution to the equation
Answer:
13.73 sq mm
Step-by-step explanation:
Area of Square - Area of Circle = Area of Shaded Region
if radius of circle is 4 then diameter is 8
the diameter is the same as the length of each side of the square
so area of square = 8² or 64
Area of Circle = 16π
64 - 16π ≈ 13.73
One way in which to approach this problem would be to treat it as an equation of ratios and to cross multiply:
<span>[(4x + 15) / 5x)] = 1/2 could be written as:
4x + 15 1
----------- = ---
5x 2
Then 8x + 30 = 5x
3x = -30, and so x = -10 (answer). Be certain to check this answer through substitution!
