Answer:
3F
Step-by-step explanation:
Force = k * x
so k = force/distance = F/2
if you were to duplicate the distance 2 times more, the F must also do so so that it's proportional
so F*2 = 2F but since it says additional 4cm, you will need to add the initial one and this one so that it's 6cm in total.
2F + F = 3F
Answer:
C
Step-by-step explanation:
Axis of symmetry is the x value of the vertex
the x value of the vertex, in form
y=ax^2+bx+c is -b/(2a)
so
y=-5x^2-10x-15
a=-5
b=-10
x value of vertex is -(-10)/(2*-5)=10/-10=-1
x=-1 is axis of symmetry
2 angle A and B are Complementary means that the sum of their measures is 90°.
2 angle A and B are Supplementary means that the sum of their measures is 180°.
Thus, if the measure of angle A is x:
the measure of the supplement is 180°-x
the measure of the complement is 90°-x
"The measure of a supplement of an angle is 40 more than two times the measure of the complement of the angle. "
let the measure of the angle be x, then we have:
180°-x=40°+2(90°-x)
180°-x=40°+180°-2x
2x-x=40°
x=40°
Answer: 40°
