Answer:
D. (5,3)
Step-by-step explanation:
The solution is (x,y). so in this case, you find the point where both arrows meet.
on the x-axis, which is positive right 5, and positive 3 up, on the y-axis
16 times the quantity of numbers, in this case 5, which = 80, then subtract each number, 80-20-20-19-13=8. X should = 8
Its not a function because there are two ages that are the same.
3x^2+12x+15=0
Then divide by 3 to get the x by itself.
x^2+4x+5=0
Factor to (x+5) (x-1) and solve for the two values of x.
Step-by-step explanation:
The ladder forms a triangle with the wall and ground.
The side of the triangle opposite of the 60° angle is 4 feet.
To find the length of the ladder (the hypotenuse), use sine.
sine = opposite / hypotenuse
sin 60° = 4 / L
L = 4 / sin 60°
L = 4 / (√3 / 2)
L = 8 / √3
L = 8√3 / 3
L ≈ 4.619 feet
To find the distance from the wall, use tangent.
tangent = opposite / adjacent
tan 60° = 4 / x
x = 4 / tan 60°
x = 4 / √3
x = 4√3 / 3
x ≈ 2.309 feet
