6x^3+13x^2+16 is the result.
Answer:
x = 4
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = 
, then using the upper 45°
sin45° = 
= 
= ( cross- multiply )
x = 4

Answer y= 16/99
Explanation:
the initial statement is
y ∝ 1/x
To convert to an equation multiply by k the constant of variation
⇒ y = k × 1/x = k/x
To find k use the given condition y = 15 when x = 5
y = k/ x
⇒ k = y*x = 8 * 2 =16
equation is
¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯
y = 16/ x
when
x = 99
then
y = 16/99
Y = 16/99
The answer is B because 7 does not evenly fit into 71 so the first box is 10 and the second box is .14285714285714or is simplified.143 or .14
To find the perimeter of a triangle, you need to find the length of each side and add all of them to find the perimeter. To find the distance between two points you use the distance formula with d as the distance between two coordinates, (x1,y1) and (x2,y2). , Hope this helps.
